‌Letter to Shareholders

STATEMENT FROM THE CHAIRMAN AND THE CEO

Dear Shareholders

The 2025 financial year was an important step forward for Ascom. We strengthened our operational performance, sharpened our customer focus, and advanced the strategic realignment that is laying the groundwork for sustainable and profitable growth. While challenges remain, our progress shows that we are moving in the right direction. Ascom generated net revenue of CHF 292.1 million, representing growth of 3.8% at constant currencies (2024: CHF 286.7 million) and of 1.9% at actual currencies. This positive development was supported by continued demand for digital healthcare solutions. Operational excellence was also

reflected in improved profitability:

Profitability increased and was driven by cost discipline, process improvements, organizational alignments, and consistent execution.

  • EBITDA rose to CHF 34.3 million (achieving an EBITDA margin of 11.7%)

  • Group profit reached CHF 15.1 million

  • Net cash position of CHF 29.6 million (2024: CHF 18.6 million), and an equity ratio of 40.0% (2024: 39.2%).

Based on its 2025 performance, Ascom remains on a solid financial footing. The strong balance sheet enables continued investment in the technological advancement of our portfolio and market development.

The Board of Directors is proposing a dividend of CHF 0.20 per share to the Annual General Meeting 2026. In addition, the Company is continuing the share buyback program as initiated in May 2025. Ascom bought back 2,158,199 shares as of 27 February 2026 for a total amount of CHF

8.7 million. The share buyback program will be continued in 2026.

Leaner, synergistic, and customer-focused organization

In early 2025, Ascom completed a substantial organizational redesign. The previous six regions were organized into three: North, South, and USA & Canada. Global functions were aligned to be

more synergistic and closer to the regions. These changes enhanced cooperation, improved the speed and quality of our project execution, and strengthened our ability to respond to customer needs with greater clarity and efficiency.

Innovation focus across all segments

Ascom also advanced its innovation agenda. We continued to made progress in integrating our various software product lines into a single platform and software stack. Platform convergence will simplify our offering in all three segments, acute care, long-term care, and enterprise, and improve our operational efficiency. Additionally, it creates significant customer value by improving the user experience, simplifying processes, and reducing costs.

He shaped Ascom with his expertise and strong strategic guidance.

‌Performance Report 2025

IMPROVED PROFITABILITY

In 2025, Ascom delivered a solid operational performance marked by renewed revenue growth, improved profitability, and continued progress in the transformation of its solutions and services portfolio.

Revenue development shows broad-based growth across all regions

Ascom's business developments in 2025 demonstrated solid strategic execution and continued investment in its healthcare communication and workflow-optimization portfolio. Ascom generated net revenue of CHF 292.1 million for fiscal year 2025, an increase from CHF 286.7 million in 2024, reflecting growth of 3.8% at constant currencies and 1.9% at actual currencies. Revenue growth was supported by stronger regional execution, stabilizing demand in mature markets, and ongoing traction in healthcare digitalization projects.

Regionally, performance varied but showed a positive development in all three of Ascom's regions. Region USA & Canada delivered the strongest performance with revenue growth of 7.3% at constant currencies, supported by one exceptionally large order delivered in December. Region South grew by 4.5% at constant currencies, driven by strong performance in Germany, Italy, and Central and Eastern Europe. Region North increased net revenue by 1.5% at constant currencies, supported by the key markets Norway and Sweden, showing steady market demand and long-term customer engagements. These results highlight robust market conditions and Ascom's ability to execute digitalization projects across diverse healthcare environments.

By market segment, the Healthcare sector continued to dominate Ascom's revenue base, accounting for 66% of total revenue (2024: 67%). The Enterprise segment represented 28% (2024: 28%), while the OEM business accounted for 6% (2024: 5%) of total revenue. The strong healthcare contribution underscores the Group's strategic focus on mission-critical clinical communication and workflow enhancement solutions. The Service business accounted for 34% (2024: 36%) while the software business increased to 14% (2024: 13%). Revenue from recurring business remained unchanged at about 27% (2024: 27%). Overall, revenue by regions and segments remained well balanced.

Incoming orders and backlog support continued momentum

Ascom recorded incoming orders of CHF 311.1 million in 2025, compared to CHF 307.4 million in the previous year. Growth of 3.2% at constant currencies and 1.2% at actual currencies confirms healthy market demand and reflects Ascom's strengthened customer relationships, particularly in regions showing stable tender activity. Region North emerged as the top performer in order intake, bolstered by double-digit growth at constant currencies in Norway and Sweden.

At year's end, the order backlog stood at CHF 310.7 million (31.12.2024: CHF 301.5 million), representing more than one year of revenue coverage and providing a good basis for continued growth into 2026.

Profitability significantly improved, driven by operational progress

Ascom's profitability improved significantly, with gross profit reaching CHF 140.8 million (2024: 133.3 million) and the gross margin rising to 48.2% (2024: 46.5%). EBITDA increased to CHF 34.3 million (2024: CHF 21.3 million), resulting in an EBITDA margin of 11.7% (2024: 7.4%). The improvement was driven by higher revenue, diligent cost discipline, organizational alignments, and further efficiency gains in project execution.

The impact of these drivers was predominantly concentrated in the second half of the year, resulting in a substantial increase in profitability compared to the first half-year of 2025.

With stable costs for depreciation and amortization, EBIT increased accordingly and reached CHF

20.3 million (2024: CHF 7.6 million). As a result, group profit rose significantly to CHF 15.1 million (2024: CHF 3.7 million), also benefiting from the absence of negative tax effects compared to the previous year. Earnings per share increased to CHF 0.43 (2024: CHF 0.10).

Solid financial position supports continued investment

Operating cash flow increased to CHF 32.6 million (2024: CHF 20.0 million), reflecting improved profitability and more efficient working capital management. Cash flow from investing activities was CHF -10.8 million (2024: CHF -15.5 million), following lower capital expenditure after completion of the office building refurbishment in Sweden, but continued focus on investments in product innovation, digital platforms, and solutions. Cash flow from financing activities was CHF -10.4 million (2024: CHF -10.8 million), reflecting the dividend distribution in April 2025 and the ongoing share buyback program launched in May 2025.

Ascom maintained a strong balance sheet, enabling the Group to continue investing in its technology roadmap and market development initiatives. At 31 December 2025, total assets amounted to CHF

199.6 million (31.12.2024: CHF 189.9 million), while cash and cash equivalents increased to CHF 29.6 million (31.12.2024: CHF 18.6 million). Ascom had no outstanding borrowings as of 31 December 2025, resulting in a net cash position of CHF 29.6 million (31.12.2024: CHF 18.6 million) at 31 December 2025, underlining Ascom's strong financial flexibility.

Shareholders' equity rose to CHF 79.9 million (31.12.2024: CHF 74.4 million), representing an improved equity ratio of 40.0% (31.12.2024: 39.2%).

Continued strategic momentum and strengthened foundations for 2026

Throughout 2025, Ascom continued advancing its long-term strategy to become a leading provider of end-to-end critical communication and workflow orchestration solutions. The Group further expanded its software capabilities, enhanced interoperability across its portfolio, and strengthened customer support and service offerings.

The improved financial performance demonstrates that Ascom is executing its strategy effectively and is better positioned to capture the growing demand for digital transformation in healthcare. With a strong order backlog, enhanced profitability, and disciplined financial management, Ascom enters 2026 with confidence and a solid operational foundation.

GROWTH

In 2025, Ascom reported a net revenue of CHF 292.1 million, which is an increase of around 3.8% at constant currencies compared to 2024. The EBITDA margin was of 11.7% (2024: 7.4%).

Revenue development in constant currencies showed an increase in all three regions. The best performance was achieved in the Region USA & Canada, with a revenue growth of 7.3%. The performance of this region was supported by one very large order, delivered in December, which contributed to growth and profitability. Region South grew by 4.5%, especially in Germany, Italy, and Central and Eastern Europe. Region North increased the net revenue by 1.5%, compared to 2024, driven by the key markets Norway and Sweden.

The market segments we operate in remain compelling and benefit from strong secular growth trends.

In the Healthcare Market, we continue to focus on strengthening our position across the different care pathways in a hospital (such as intensive care units, general wards, operating rooms, emergency departments, rehabilitation centers), as well as in long-term care homes and home care. Given the ageing population, the increase in chronic diseases, and the continued shortage of care personnel, Ascom's solutions are a good fit to enable better delivery of care, bridging the last mile through critical communication and collaboration solutions, automation of workflows, and digitalization of care. Here, we improve operational efficiency in hospitals and care homes and create value for our customers, providing better outcomes for both patients and care personnel at lower cost.

Ascom's differentiated solutions range from software solutions for MDI (Medical Device Integration), alarm management and alarm orchestration, clinical surveillance, and PDMS (Patient Data Management System) to mobility devices and nurse call systems, which provide alarming, monitoring, and sensoring capabilities in addition to communication.

In the Enterprise Market, Ascom brings significant value to its customers with mobility solutions and software propositions designed to improve workflow efficiency and workplace safety, alarm management, and communication and collaboration between workers. As such, we enable better and more efficient working conditions and keep workers safe in their respective environments.

In 2025, we continued our portfolio transformation including integrated solutions, which can be deployed on-site and via the cloud. Cloud-based solutions see fast-increasing adoption in enterprise, and long-term care. They open new market opportunities for Ascom as they allow us to address more successfully new or more price-sensitive market segments not addressed before.

STRATEGY EXECUTION & INNOVATION

Platform integration and simplification

In 2025, Ascom continued to make progress in integrating our various software product lines into a single platform and software stack. Platform convergence will simplify our offering in all three segments, Acute Care, Long-Term Care and Enterprise, and improve our operational efficiency. More importantly, it creates significant value for customers by improving the user experience, simplifying processes, reducing costs, and enabling better measurement of the improvements our solutions deliver to customers. The solutions are centered around eight core capabilities integrated into an easy-to-deploy and easy-to-configure platform, providing tangible customer value and further building on Ascom's significant market share globally.

  1. Alarm management, a core capability for any healthcare setting, where innovation around silent alarming and alarm filtering helps fight alarm fatigue for staff and overall better recovery conditions for patients

  2. Workflow management, driving action by care and support staff, where clinical and operational workflows can continuously be improved and enriched by information obtained from an increasing set of sensor networks

  3. Surveillance, where near-real-time patient information obtained from medtech equipment and (wearable) sensors is provided in the hands of the (mobile) care staff

  4. Decision systems, where usage of Artificial Intelligence (AI), heuristics, and Machine Learning techniques augment and support the detection of patient deterioration and proactive alarming or reactive alarm filtering

  5. Communication & collaboration, helping staff to communicate in real time and work in teams around patients while providing continuity over shift changes

  6. Analytics and reporting, providing actionable insights on process KPIs and providing detailed reports for operational and compliance purposes

  7. Patient Data Management (PDMS), where digitization of capturing information around patients reduces human error, frees up time from caregivers, and allows for richer information in Electronic Medical Records (EMR)

  8. Asset tracking of patients and workers, devices and care staff, assisting in automated workflows and providing insights that allow for better utilization of assets in healthcare institutions and enterprises.

Ascom's solutions address key customer needs, such as

  • addressing the shortage of staff

  • moving from reactive to proactive care and workflows, driving better patient outcomes while reducing burden on care staff

  • scaling up hospital and enterprise systems to leverage economies of skill and scale

  • increasing efficiency and effectiveness of workflows, leveraging a growing set of sensors (IOT) & real-time locating systems (RTLS)

Customer value of the Ascom Core Platform:

  • Highly scalable

While all three segments, Acute Care, Long-Term Care and Enterprise, rely on mission-critical communication, real-time information flows, and increasingly sensor-based insights, each market follows a different pace of digitalization and requires specialized capabilities to maximize customer value.

In Acute Care, healthcare systems worldwide continue to evolve toward a seamless combination of alarm tracking and clinical surveillance, enriched by AI-driven decision support and actionable workflow insights. Hospitals increasingly operate at scale and require efficient, secure toolchains that can introduce new functionality rapidly and share configurations across multiple sites.

The Long-Term Care market is rapidly adopting sensor-based surveillance, resident activity monitoring, and AI-supported decision systems, delivered in a pay-as-you-use SaaS model that requires minimal on-site IT expertise.

Care provision is increasingly shifting to resident homes, where family members and professional caregivers rely on easy-to-deploy digital tools. Ascom continued advancing a cloud-native Long-Term Care platform that integrates Ofelia and Smart Sense, ensuring stronger differentiation from major competitors in this expanding segment.

Combined with Ascom's nurse call systems and mobility solutions, Ascom becomes a referencepro-vider of healthcare systems of insights and actions.

The Enterprise market is undergoing a clear shift toward sensor-based surveillance, IoT (Internet of Things)-, Artificial Intelligence (AI)-, Machine Learning (ML)-enabled decision systems, and automated workflows, allowing organizations to improve staff efficiency, operational uptime, and asset utilization. Critical communication and personal safety remain core needs-particularly in industries such as manufacturing floors, secure establishments, blue light services, and lone worker environments.

Ascom's Enterprise portfolio combines mobility solutions (Paging, DECT, WiFi, Cellular/5G), RTLS, third-party sensor integration and cloud-delivered SaaS capabilities, all built on the same highly scalable and reliable platform used in healthcare.

To remain the partner of choice for enterprises transitioning to private 5G environments and modern communication architectures, Ascom continues to expand its offer with industry-specific features and cross-technology transmission capabilities. Upselling SaaS services-ranging from alarm management to location-based worker protection-plays an increasingly important role across small, medium, and large enterprises.

Starting in 2024, Ascom witnessed further growth, particularly in Long-Term Care and Enterprise customers buying its platform solutions under a SaaS (Software as a Service) subscription model.

The SaaS Staff Safety (Software as a Service) provides a comprehensive, reliable, and secure solution for employees to raise alarms quickly-manually or automatically- while ensuring swift and accurate responses, also detecting potential safety issues that could occur with employees in lone worker situations. The transition from traditional on-premises installation to a cloud-based model delivers significant operational and economic value to customers. It offers better flexibility, scalability, and cost-efficiency, lowering upfront investment while allowing customers to more easily respond to the organization's needs as they change.

In 2025, this journey continued by enabling increased functionality as SaaS and extending the offer to large customers.

Driving further Innovation with AI

Since 2023, Ascom has been working on the next-generation alarming and alarm orchestration platform, leveraging contextual patient data and Artificial Intelligence (AI) for more informed decision-making, reduction of alarm overload, and better patient care.

Ascom is a partner of the "Smart and Silent ICU" research project awarded by the EU Innovative Health Initiative (IHI) to investigate the clinical benefits of networked medical technology and the connection of AI modules. The focus of the research project is to reduce the burden of alarm overloads and improve data evaluation in healthcare with AI applications.

In 2025, Ascom, B. Braun, and Dräger launched the silent ICU (Intensive Care Unit) solution out of this project, demonstrating the future for ICU care areas to hospitals worldwide.

Ascom continued its participation in this project, installing its cloud-native healthcare platform at the University Medical Center (UMC) Utrecht to develop and clinically validate algorithms for the detection and prediction of adverse health outcomes and specific syndromes based on individualized and contextual patient data.

We are very proud to be at the forefront of this state-of-the-art project and breakthrough innovation.

AI will provide significant potential to increase our own and our customers' operational efficiency.

OPERATIONAL EFFICIENCY

In April 2025, Ascom realigned and restructured its organization to achieve continued progress on productivity and efficiency. A comprehensive implementation plan was pursued in the second half of the year, delivering tangible benefits to our operations and to our customers. Efforts to automate and simplify installation processes further contributed to operational efficiency, time savings, and reduced complexity across our projects.

Cost efficiency will remain a key focus for Ascom in the years to come, as we further benefit from the streamlined organization. For example, the introduction of the Global Operations unit allows us to consistently implement best-practice processes in project implementation and customer care across the regions, thereby reducing complexity, enhancing customer experience, and lowering cost.

PEOPLE, CULTURE & SUSTAINABILITY

Our people are the cornerstone of our success. In 2025, we continued fostering a culture of performance, empowerment, accountability, and collaboration, and focused on employee engagement. We also invested further in talent development to prepare future-ready leaders and to ensure effective succession planning, with new learning tools for all employees and leadership development programs.

Our employee engagement initiatives aligned personal growth with organizational goals, reinforcing our "One Ascom" culture.

Sustainability as a Strategic Enabler

At Ascom, sustainability is integral to our business strategy and our value proposition to customers, employees, and investors. We are committed to environmental stewardship and to social and ethical responsibility across our operations, with the explicit goal of creating added value for our customers while helping them meet their own sustainability objectives. Additionally, we strive to assist our customers and partners in achieving their own sustainability objectives.

Our sustainability program is overseen at the highest management level, ensuring ESG (Environment, Social, Governance) priorities are embedded in strategic decision-making and execution.

In 2025, we registered with the Science-Based Targets initiative (SBTi). A milestone that anchors our decarbonization journey to globally recognized climate science and sets a clear path toward validation and reduction targets. With this, we are initiating the process that will lead to target validation by the end of 2027.

In 2025, we introduced new repair standards for all DECT/VoWiFi handsets and pagers. This change reduced overall cover exchanges by 25%, delivering significant material savings in high-volume markets. Further, we implemented the EU energy label for Myco 4, aligning with newly introduced eco-design regulations. We will continue focusing on the development of the eco-design roadmap, preparing for the Digital Product Passport for batteries expected in 2027.

Talent management and DEIB (Diversity, Equity, Inclusion, and Belonging) are key materiality topics of Ascom, with strategic focus. In 2025, we made significant progress in our retention of talent and our leadership program. The Executive Committee launched the Ascom Leadership Exchange (ALE) program, including forty employees of different management levels, strengthening exchange and collaboration. In 2026, we will define clear career paths for critical roles, strengthen our employee value proposition, and implement a transparent talent management to attract and retain top talent. We will continue enhancing leadership competencies and revitalize our New Joiners Program (as referenced in 2025 actions), maintaining focus on diversity, equity, inclusion, and belonging (DEIB) to progress toward 30% female leaders by 2030 and sustaining high retention.

To reinforce stakeholder trust, we are proud that our efforts on ESG have been recognized by different external rating agencies. EcoVadis, but also Inrate and Ethifinance, valuated our efforts with improved ratings.

Our ESG agenda is designed to create customer value and strengthen competitiveness. Product eco-design improve success in tenders, repairability reduces material use and lifecycle cost, and transparent reporting builds investor confidence. By aligning ESG with enterprise priorities, we ensure sustainability is a key enabling platform for growth and resilience. In 2025, Ascom made significant progress toward becoming a more sustainable and responsible company.

More information can be found in the Sustainability Report (page 17 ff).

Strategic Ambitions regarding Sustainability

Our materiality driven framework focuses on five ambitions:

  1. Climate neutral operations based on SBT (Science-Based Targets) reduction plan -achieving full carbon neutrality by 2040 and net zero by 2050.

KSB leads in digital care through innovations like integrating Ascom Myco 4 smartphones, which send medical alerts directly to nurses' mobile devices for continuous patient monitoring, using Innovative technology for the "hospital of the future."

The customized patient call system is built into the Trifact's bed terminal, keeping medical calls separate from hotel services and delivering them straight to staff. The installation emphasized smooth integration and real user benefit, resulting in fewer unqualified calls, improved processes, and greater patient satisfaction.

Ascom's custom platform upgrades have boosted efficiency and quality, supporting the hos-pital's vision for the future.

This solution earned nominations for the Digital Economy Awards 2025, and KSB won the European Healthcare Design Award 2025 for its new facility.

STATEMENT FROM THE CHAIRMAN AND THE CEO

Dear shareholders, customers, employees, and partners,

Ascom's solutions support patients, caregivers, and professionals in critical environments. This responsibility shapes how we operate. We view environmental stewardship, social responsibility, and strong governance as important parts of our longterm resilience and competitiveness. ESG remains a strategic priority: it strengthens customer trust, improves product durability, supports operational efficiency, and prepares us for evolving regulatory requirements.

The Board of Directors confirms the materiality topic assessment of our ESG priorities and ambitions. Our ambition is steady, our commitment firm, and our approach grounded in realism and transparency. The 2025 Sustainability Report, including the TCFD Report (Task Force on Ci-mate-related Financial Disclosures), was prepared in line with Swiss regulations and the GRI standard (Global Reporting Initiative).

Progress in 2025

In 2025, we enhanced the accuracy and maturity of our sustainability work. A more structured data collection tool helped us improve the quality and reliability of our environmental data. Independent ratings from EcoVadis, Inrate, and Ethifinance reflect our improvement and offer guidance for further progress.

We also completed our registration with the Science-Based Targets initiative (SBTi) and are now preparing for the validation phase.

We continued to optimize the environmental performance of our products. Updated repair standards for DECT and VoWiFi devices reduced material use and extended product lifecycles. We also implemented new European energy labeling requirements to align our portfolio with upcoming regulations. Product-related emissions remain our largest footprint contributor.

Despite these measures, our preliminary Scope 1-3 emissions increased due to higher production volumes and a rise in inbound air freight driven by volatile demand and supply chain disruptions. These developments highlight the need to strengthen supply chain planning and collaborate closely with partners to reduce emissions.

We also advanced our social and governance initiatives, including improvements to onboarding, training, and leadership development-key elements of a strong, engaged organizational culture.

Journey ahead

Our priorities for 2026 remain clear: deliver customer value, strengthen operational excellence, and deepen our sustainability efforts. We will continue developing cloud-based and energy-efficient solutions, integrating circular design principles and working closely with suppliers to improve joint environmental performance.

Preparing for SBTi-validation in 2027 will be a key focus in 2026.

As regulatory expectations rise, comprehensive product-related environmental data will become increasingly important. We are preparing for new frameworks such as the European ecodesign regulation and the Digital Product Passport, which will influence procurement, design, and customer requirements.

We will further strengthen leadership competencies and expand development opportunities to support a collaborative and inclusive culture. In parallel, we will monitor regulatory developments in the EU and Switzerland. Although Ascom currently falls outside the European Corporate Sustainability Reporting Directive (CSRD), adjustments of the Swiss framework are to be expected.

‌SUSTAINABILITY AS A STRATEGIC DRIVER

Ascom understands sustainability as an opportunity for growth, innovation, and long-term value creation. The Company acts on the conviction that sustainable practices deliver real benefits for customers, employees, and shareholders. The Board of Directors oversees the Corporate Sustainability Strategy, sets goals, and reviews progress. The Audit Committee nominated Dr. Monika Krüsi as main contact on the board for ESG-related activities.

The Materiality Matrix: Thirteen material topics

The Materiality Matrix evaluates both our impact on sustainable development and the relevance of these factors to Ascom's corporate success. The Matrix shapes our strategic focus on four key pillars: Planet, Product, People, and Governance. Each priority within these pillars is evaluated for its dual sig-nificance-to both shareholders and the broader world-ensuring that Ascom's initiatives deliver meaningful results. The matrix identifies thirteen material topics highlighting the areas where Ascom believes the Company can achieve the greatest impact on environmental, social, and economic aspects through our business activities. Ascom's Materiality Matrix is approved by the Board of Directors.

Ascom recognizes that materiality analysis and the resulting matrix are not static. Changes in legislation, evolving market dynamics, and shifting requirements of employees, customers, and other stakeholders can influence the dimensions of our focus.

Measures & Ambitions

Ascom views sustainability not as an obligation but as a catalyst for innovation, resilience, and long-term value creation. The Company has set clear climate ambitions: achieving carbon neutrality by 2040 and reaching net zero emissions by 2050, using 2024 as the base year. This ambition and commitment has been defined by the Ascom Board of Directors.

Progress 2025

In 2025, Ascom continued to focus on improving data quality, enhancing transparency, and establishing a robust methodology. Key efforts included refining environmental data collection. The reporting period spanned from 1 August 2024 to 31 July 2025. End of July 2025, Ascom employed 1,423 FTEs.

In 2025, total CO₂e emissions rose by 8%, from 18,441 tCO₂e in 2024 to 19,922 tCO₂e in 2025, resulting in an emissions intensity of 14.00 tCO₂e per employee. All emissions relevant sites were included, and at least 95% of Scope 1 and 2 emissions were captured. Overall, the three largest emission sourc-es-Purchased Goods & Services, Business Travel, and Transport-accounted for 88% of all emissions. The increase was mainly driven by higher volumes of purchased goods, especially smartphones, which affected the GHG Balance Sheet in different categories: Scope 3.1 due to the higher volume of purchased good, Scope 3.4 upstream transportation between the manufacturer's site in Asia and the warehouse in Sweden, due to a higher volume of purchased goods. Since the categories "use phase of sold products" and "end-of-life treatment of sold products" are modeled based on the quantity of purchased goods, the corresponding emissions also increased. Emissions from the "end-of-life treatment of sold products" rose by 20%, while the "use phase of sold products" saw a more modest increase of 7%. The smaller increase in the latter category can be attributed to the fact that the electricity used for

these products is now less emission intensive compared to the base year.

The second main reason for the increase of emissions is improved data quality. The Company launched in 2025 a new data collection tool, in which all collected regional data on energy consumption for buildings, heating, downstream transportation, fleet, and business travel were collected and analyzed. The tool enabled better validation of data sources and in some cases, let to more detailed data compared to 2024. This was for instance the case for heating emissions.

Other categories showed normal fluctuations, such as business travel and refrigerants. Commuting emissions shifted in line with fluctuations of the number of employees, and electricity emissions decreased due to reduced surface area and due to the sourcing of more renewable energy compared to the base year. Heating emissions, however, increased because the improved data quality revealed that a particular region used more emission-intensive heating than was recorded in the base year. However, this change was not substantial enough to warrant a recalculation of the base year. Capital goods emissions remained lower than in the 2024 base year, which had included a major office renovation in Gothenburg.

Outlook

Ascom's three hotspots, responsible for 88% of all emissions, are purchased goods & services, business travel and transports. Looking ahead, Ascom will mainly focus on efficient measures in circular product design and sustainable supply chain. The Company will continue improving environmental data quality and begin implementing concrete regional reduction measures. The Company has registered with the Science-Based Targets initiative (SBTi) and will focus in 2026 on preparing for the validation process planned for 2027 and aligning the Company's decarbonization roadmap with its SBTi commitments.
