Board of Director's Report 2025

1. OVERVIEW

Teleste is an international technology group whose products and solutions make it possible to build a networked and secure digital society. The company's solutions enable broadband and television services, secure safety in public places and support the smooth use of public transport.

The Company develops its business in line with its strategy within selected technology and market areas. This is implemented through the design and delivery of digital technology solutions that support customers' core business operations. The Company provides hardware and software products as well as value-added services. The development of these solutions requires significant investment in research and development across all areas of operation. The Company seeks to reduce the environmental impact of its operations.

In 2025, geopolitical and trade policy tensions continued to intensify, creating further uncertainty and change in the operating environment. Many international companies were required to rapidly adapt their operating models in order to navigate frequently changing rules and decisions and to mitigate, for example, the financial and operational impacts of tariffs and exchange rate fluctuations. Tensions in Eastern Europe, the Arctic region, the Middle East, and the China-Taiwan region continued to be reflected in the macroeconomic environment.

Despite the changes in the operating environment, Teleste increased its net sales, particularly in the North American market, and significantly improved its profitability in both business segments. Due to agility in operating models, the trade-policy impacts related to tariffs remained limited, although the company was not entirely immune to the impacts of exchange rates. The company's cash flow remained consistently positive throughout the period.

Overall, the company continued to make steady progress during financial year 2025 towards its long-term strategic growth targets for 2030.

In the Broadband Networks business segment, the demand for broadband technology returned to growth in 2025, driven by network infrastructure investments particularly in North America.

The company expanded its North American customer base to 20 operator customers, and the relative share of net sales represented by 'North America and the rest of the world' increased to 31% from the previous financial period's level of 16%. This trend is expected to continue in the coming years as the overall market grows. In order to improve its operating model and working capital requirements, the company started to ramp up factory production in Mexico in the latter half of 2025. Customer consolidation in the North American network market is driving changes in the operating environment. The Company actively monitors these developments, anticipates their effects and responds as needed.

In Europe, customer investments were at a moderate level in 2025 due to the higher interest rate levels in the early part of the year and general economic uncertainty. In the medium term, the demand for broadband services and the European network equipment market are expected to remain flat or grow moderately, due to competition among network operators to provide reliable high-speed broadband connections to households and companies. Teleste is the market leader in its industry in Europe, and the company intends to further increase its market share.

In the Public Safety and Mobility business segment, the market for public transport information and security systems continued to grow steadily in 2025. The company's customer base expanded amongst both rolling stock manufacturers and public transport operators. Growth was also achieved in the maintenance and service business, which generated a stable revenue stream alongside new projects. Investments in software development, artificial intelligence and cyber security increased, and the trend is expected to continue in 2026.

Urban development, the increasing use of sustainable public transport solutions and the integration of digital systems into daily life provide a strong and long-term foundation for the growth of public transport information solutions. At the same time, ensuring the security of critical infrastructure with smart digital technology creates new growth opportunities in the market. The operating environment has developed in a more favorable and predictable direction, offering steady growth. Teleste's strong position supports solid business growth and sustainable development.

3. NET SALES AND PROFITABILITY

The formulas for any alternative performance measures are presented in section 19 of the Report of the Board of Directors.

The net sales of the Group amounted to EUR 138.6 (132.5) million, representing a 4.6% increase, with growth in both segments. The net sales of the Broadband Networks segment totaled EUR 82.8 (78.2) million, representing an increase of EUR 4.6 million (5.8%). The growth was driven by increased volumes of intelligent amplifiers to the North American market, offsetting the strong European deliveries recorded in the first quarter of the comparison period. The net sales of the Public Safety and Mobility segment totaled EUR 55.9 (54.3) million, growing 1.6 million (2.9%) from the comparison period. Performance varied across business areas, which partly compensated each other.

In terms of the geographical distribution of net sales, the share of "North America and other countries" increased to 25.2% (15.2%), which was particularly due to significant growth in the North American market for the Broadband Networks segment, and the Public Safety and Mobility segment's strategic proj

1-12/2025 1-12/2024 Change %
Net Sales 138.6 132.5 4.6 %
Adjusted EBITDA 12.1 9.3 29.1 %
Adjusted EBIT 7.1 4.2 69.7 %
Orders received 138.2 124.9 10.7 %
Order backlog 114.5 115.0 -0.4 %
Average personnel 633 673 -5.9 %

ect deliveries to North America and Middle East. Finland accounted for 7.9% (8.7%) of net sales, the Other Nordic countries for 9.3% (9.2%), and Other Europe for 57.6% (66.9%).

The Group's adjusted EBITDA was EUR 12.1 (9.3) million, representing an increase of EUR 2.7 million, or 29.1%. The Group's adjusted EBITDA margin was 8.7% (7.0%), representing a year-on-year increase of 1.6 percentage points. Group's material and manufacturing costs were 46.3% (49.9%) of net sales. The improvement of 3.6 percentage points was due to different product and market mix, higher share of service and software revenue, savings in material expenses, and improvements in production efficiency. Personnel expenses increased by 10.8% and amounted to EUR 45.4 (41.0) million. In the comparison period, the Company's temporary layoffs reduced personnel expenses, while investments in the North American business increased during the reporting period.

The Group's EBITDA was EUR 11.8 (6.4) million, representing an increase of EUR 5.3 million. The adjusted items in the comparison period were related to restructuring costs and strategic development projects. The EBITDA margin was 8.5% (4.9%).

The Group's adjusted operating profit was EUR 7.1 (4.2) million, and the adjusted operating profit margin was 5.1% (3.2%).

Operating profit grew significantly and was EUR 6.8 (-5.4) million, representing 4.9%

(-4.1%) of net sales. The increase in operating profit was partly due to the EUR 2.9 million restructuring costs and the non-recurring R&D impairment of EUR 6.7 million reported as adjustment items in the comparison period.

The Group's net financial expenses were EUR -3.8 (-1.7) million, representing an increase of EUR 2.1 million. The increase was mainly due to unrealized foreign exchange losses of approximately EUR 0.9 million, realized foreign exchange losses of EUR 0.5 million, negative changes in foreign exchange and interest rate hedges amounting to EUR 0.4 million, the effective financial expense impact of refinancing arrangement fees and higher interest expenses totaling EUR 0.3 million. Additionally, in accordance with the company's hedge accounting policy, the fair value of USD currency hedges recognized in other comprehensive income increased by EUR 0.1 million during the period.

Direct taxes for the reporting period amounted to EUR -0.4 (1.0) million. Driven by strengthening profitability and an improved outlook, the Group companies have recognized previously unrecorded deferred tax assets of EUR 0.3 million in their financial results. The deferred tax in the comparison period was due to the reversal of the tax liability for the write-down of capitalised R&D expenses.

The Group result for the review period was EUR 2.6 (-6.1) million. Earnings per share was EUR 0.15 (-0.32).

5. PERSONNEL

The Group employed 633 (673) people on average in January-December 2025. At the end of December, the Group employed 630 (630) people, of whom 28% (31%) worked abroad. At the end of the financial period 2024, the Group employed 630 people. The company has specified the reporting of employees during 2025 and, therefore, the previously reported number of employees at the end of the financial period 2024, 619, has been

restated to correspond to the reporting practice applied in the current financial period.

During January-December, personnel expenses increased by 10.8% year-on-year to EUR 45.4 (41.0) million. During the comparison period, the company's temporary layoffs lowered the personnel expenses, while investments in the North American business increased during the reporting period.

To incentivize its personnel, the Company has a bonus program in place. The short-term compensation of senior management consists of base salary, fringe benefits, and an annual bonus, determined primarily based on the development of the Group's and business segments' revenue and profitability. In addition, the Company operates share-based incentive plans for its key employees.

6. FINANCING AND CAPITAL STRUCTURE

At the end of the period under review, the Group's interest-bearing debt stood at EUR 28.7 (34.2) million, with short-term loans from banks representing EUR 6.2 (8.2) million of that amount. Interest-bearing liabilities associated with leases capitalized in accordance with IFRS 16 amounted to EUR 4.2 (4.5) million, of which EUR 1.4 (1.4) million were short-term liabilities. The Group's cash and cash equivalents amounted to EUR 9.1 (8.8) million. At the end of December 2025, the amount of unused binding credit facilities was EUR 16.0 (14.0) million.

The Group's total assets at the end of the period under review stood at EUR 122.7 (121.2) million, and own equity amounted to

EUR 57.9 (54.8) million. The Group's equity ratio was 47.6% (45.4%) and the net gearing ratio was 33.9% (46.3%).

In the third quarter of 2024, the company signed a syndicated refinancing arrangement that includes a repayable loan, credit limits and a non-binding guarantee limit. All financing agreements include financial covenants regarding the minimum equity ratio, the maximum net debt to adjusted EBITDA ratio and the minimum liquidity. The company met all of its financial covenants. Enterprise mortgages totaling EUR 68.9 million are used as collateral for the financing agreements.

At the end of the review period, the company's financing agreements included:

  • A EUR 26.0 million repayable loan maturing in August 2027, the principal of which was EUR 21.5 million on December 31, 2025. The loan is amortized four times a year in installments of EUR 0.8 million.
  • A EUR 15.0 million binding Revolving Credit Facility (RCF) maturing in August 2027, of which EUR 3.0 million was in use on December 31, 2025.
  • A EUR 4.0 million binding credit limit, valid until August 2027. On December 31, 2025, EUR 4.0 million of the credit limit was unused.
  • A EUR 8.0 million non-binding bank guarantee limit
  • The financing agreement includes two conditional one-year extension options, of which it was agreed that the first option would be used during the reporting period.

7. SEGMENT RESULT

In 2025, the company had two reportable business segments for financial reporting: Broadband Networks and Public Safety and Mobility. The Group's common functions are treated outside segment reporting.

The figures presented in this "Segment result" section for the reportable business segments are based on the figures reported to the company's management for the purpose of assessing the result and allocating resources. The segments' results are presented as Adjusted EBITDA and Adjusted EBIT. The adjusted EBITDA and adjusted EBIT figures do not take into account items affecting the comparability of the operational performance between reporting periods. Such items include, for instance, profit or loss from the divestiture or closing down of operations, profit or loss from the reorganization of operations, impairment losses, expenses related to significant strategic changes or other extraordinary income or expense related to the operations, amongst other things. More information on the Group's operating and reporting structure and the reconciliation of segment figures with Teleste Group's figures is provided in the notes to the consolidated financial statements under "Segment reporting".

BROADBAND NETWORKS

The net sales of the Broadband Networks segment totaled EUR 82.8 (78.2) million, representing a year-on-year increase of EUR 4.6 million (5.8%). Deliveries of 1.8 GHz DOCSIS 4.0-compliant intelligent amplifiers to North America increased significantly. The comparison period included significant deliveries to

Shares and shareholders

the European market during the first quarter. The revenue share of "North America and other countries" increased to 31.1% (16.0%), primarily due to the increased delivery volumes to North America. Finland accounted for 9.3% (9.8%) of net sales, Other Nordic countries for 6.7% (9.8%), and Other Europe for 53.4% (64.4%).

The Broadband Networks segment's adjusted EBITDA was EUR 10.9 (8.9) million, representing an increase of EUR 2.0 million. The increase in EBITDA was driven by higher net sales, material and production costs savings, as well as improved product and market mix. The company has continued to accelerate its investments aimed at strengthening its market position in North America. In addition, in the comparison period, other expenses and personnel expenses were lower due to temporary cost-saving actions. The adjusted EBITDA margin was 13.2% (11.4%).

The adjusted operating profit of the Broadband Networks segment was EUR 8.3 (6.3) million, representing an increase of EUR 2.0 million. The adjusted operating profit margin was 10.1% (8.0%).

PUBLIC SAFETY AND MOBILITY

The net sales of the Public Safety and Mobility segment increased 2.9%, totaling EUR 55.9 (54.3) million. Performance varied among the different business areas within the segment. Deliveries to public transport operators have been particularly strong compared to the reference period. The Video security business developed favorably, particularly in North America and Middle East. Net sales in the Services business exceeded the level of the comparison period. The net sales from deliveries to the rolling stock manufacturers remained below the reference period, as customers postponed deliveries to a later schedule than initially anticipated.

The revenue share of "North America and other countries" increased to 16.6% (14.1%) due to larger project deliveries to strategic customers, especially in video security. Finland accounted for 5.7% (6.1%) of net sales, the Other Nordic countries for 13.2% (8.3%), and Other Europe for 64.5% (71.6%). The decrease in Other Europe's contribution was primarily due to lower deliveries to train manufacturers according to normal project timing fluctuations.

Full-year profitability improved considerably in the Public Safety and Mobility -segment, due to lower material and production service costs, as well as a more favorable project mix compared to the comparison period. The increase in personnel expenses was offset by a decrease in other fixed costs. This was driven by successful recruitment efforts, which enabled some previously outsourced tasks to be handled in-house.

The adjusted operating profit was EUR 3.4 (2.0) million, representing an increase of EUR 1.4 million. The increase in profit was a result of the abovementioned profit levers as well as lower amortizations compared to the comparison period. The adjusted operating profit margin increased to 6.0% (3.7%).

8. GROUP STRUCTURE

The parent company has a branch office in the Netherlands and subsidiaries in 11 countries outside Finland.

9. INTANGIBLE ASSETS

The company's intellectual property rights are safeguarded through the confidentiality of device designs and software source codes, their secure storage, as well as selected patents and patent applications. In the Broadband Networks business, the company follows a North America-centric IPR strategy, as a result of which Teleste has received 32 patents for cable TV network devices and 9 applications are pending. The inventions relate to the features of smart network devices that enable automatic functions and the optimisation of energy consumption. In the Public Safety and Mobility business, the company follows an IPR strategy focused on public transport solutions, which has resulted in Teleste receiving 35 patents. Patents have been used to protect innovations concerning the transfer and management of video security data in public transport. The company also ensures that its products do not infringe on other intellectual property rights by keeping contracts up to date, providing staff training, and regularly monitoring competitors' patents. The company also has legal expenses insurance.

10. THE MOST SIGNIFICANT BUSINESS RISKS

Teleste's business is exposed to risks that may arise from changes in the business environment or the company's operational activities. The risk factors described below may have an adverse effect on the company's business operations or financial position. However, other risks that the company is currently not aware of, or which are currently not estimated to be significant, may also become significant in the future.

The Board of Directors reviews essential business risks and their management quarterly and whenever necessary. Risk management constitutes an integral part of the strategic and operational activities of the business areas. Risks are reported to the Audit Committee and the Board of Directors on a regular basis.

10.1. STRATEGIC RISKS

In 2025, the global geopolitical situation changed significantly, which has also made Teleste's operating environment more unpredictable.

Changes in the operating environment may have material impacts on the availability, prices and usability of various materials and components, or the global supply chains in a more general sense, for example. There may also be impacts on the growth or development of the company's various target markets.

The company must actively anticipate potential changes in the operating environment and markets and prepare for them through a variety of measures. Technological transitions, such as telecommunications operators' migration to next-generation technologies, may significantly change the competitive positions of the current suppliers and attract new competitors to the market. Intensifying competition may also lead to increased price pressure, which could impact the profitability of the business.

The right technology choices, product development investments, incorporating new technologies into the business and their timing are key to success. Product development involves calculated risks. If those risks materialize, the return on product development investments may diminish. Especially in the Broadband Networks business, product development decisions are often made without customer commitments, which is typical for the industry. This risk may be mitigated by attempting to negotiate customer commitments or shared risk-taking agreements.

New technology standards may include alternative technology variants for different features, which may increase product development investments and the associated risk for technology providers. As commercial products enter the market, operators may change their technology choices from one standard variant to another. This could result in a scenario where not all product development investments align with the projected market size.

Strategic choices related to the new technology chosen by the company and, for example, the use of artificial intelligence, may prove incorrect, or their implementation may be too slow or insufficient in relation to the competitive situation, which may weaken the company's competitiveness in the long term.

Expanding business operations to new markets often involves risks. The company's expansion into the North American broadband market has progressed well, but if changes in the market were to occur, they could have an impact on the achievement of the company's longer-term strategic goals.

The largest key customers represent a significant share of the net sales of each customer segment. Potential changes in procurement strategy or supplier selection by customers may lead to a contraction of business volumes and weakening profitability.

Consolidation among customers or competitors may occur in the company's operating industries, which could alter the market dynamics and affect Teleste's competitive position and, consequently, its success in the market. Charter Communications and Cox Communications announced a merger in 2025. In connection with the merger, prior to the finalization of the transaction, the parties may optimize or postpone their investments, which may temporarily weaken the market. Consolidation among operators may also accelerate the need for corresponding moves among technology suppliers.

In addition to the level of market demand, the competitiveness of the company's product and service offering is a key factor with regard to growth and profitability. Failure to anticipate or respond to changes in customer requirements, competitors' offerings or changes in business models may lead to a deterioration of the company's competitiveness.

Economic cycles and, in particular, fluctuations in the level of investment activity among broadband network operators and public transport operators affect the demand for the company's products and services. Potentially changing inflation environments, interest rate levels and market subsidies by various governments may also affect the company's customers' financing, profitability, ability to make investments and, consequently, the demand for the company's products and services.

Negative impacts on the company's brand and reputation may affect its business and financial performance. Potential reputational damage could arise due to significant problems related to deliveries, products or service quality, or a cyber security incident, for example.

10.2. OPERATIONAL RISKS

The import tariffs imposed by the US administration starting from April 2025, along with other broader trade policy measures, occasionally changing customs regulations, potential counter-tariffs, export restrictions and other trade barriers may have an impact on the company's business and profitability. In addition, potential restrictions and tariffs on exports from the supplier countries in the company's subcontracting chain may complicate supply chains and affect the availability and price of materials. The company strives to prepare for various scenarios and mitigate the impacts through proactive measures but, in an operating environment that is in a constant state of flux, it may not be possible to avoid or compensate for all impacts.

Globally growing investments in data centers and new technologies increase the demand for semiconductors. This may limit the availability of the components required by the company, as some of the components compete for the same production capacity. This can occasionally lead to uncertain or limited availability of materials and components, which may result in additional costs.

Customers' investment levels and order volumes vary significantly between different periods due to, for example, optimization of the customers' own inventories and transitions of technology generations. Predicting volume fluctuations and preparing for them is often difficult, which can lead to inaccurate assessments of the company's production capacity and its timely adjustment to meet customer demand at any given moment, taking into account the needs of different market areas.

Comprehensive system and project delivery pricing, planning and resourcing are partly based on estimates and therefore include risks during execution. Projects may be large in size and take place over several years, setting high demands for the project execution and management and involve technical, legal and financial risks. Some of the Public Safety and Mobility business unit's projects in the public transport segment are partially fixed-price projects or subject to limited price increases due to the nature of the industry, which means they may involve a margin risk when costs increase. Project delays may lead to contractual penalties or other sanctions.

Shares and shareholders

Various technologies are used in Teleste's products and solutions, and the intellectual property rights associated with the application of these technologies can be interpreted in different ways by different parties. Such difficulties of interpretation may lead to investigations or court proceedings.

Customers have very demanding requirements for the performance of products, their durability in challenging conditions and their compatibility with other components of integrated systems. Regardless of careful planning and quality assurance, complex products and solutions may fail in the customer's operational environment and lead to repair obligations.

Several information systems are critical to the development, manufacture and supply of products to customers. The maintenance of information systems and deployment of new systems involve risks that may affect the ability to deliver products and services.

Competent employees with the necessary qualifications and skills play a key role in the achievement of the company's objectives. The development of personnel competence, employee engagement and recruitment involves risks that influence how competitiveness is maintained and developed.

Labor market actions may occasionally affect the company's ability to operate. Labor action in production or export logistics, for example, may interrupt deliveries to customers. Cost and personnel reductions implemented by the company from time to time can cause uncertainty amongst personnel and may lead to employee turnover, which complicates the company's operations.

The company strives to prepare for different scenarios and limit the impacts through proactive measures. However, in a constantly changing operating environment, it may not be possible to anticipate, avoid or fully compensate for all impacts.

10.3. RISKS RELATED TO UNEXPECTED EVENTS AND SECURITY

Physical damage caused by accidents (such as fire), extreme weather events, natural disasters, terrorism or other exceptional circumstances may disrupt the availability of raw materials or components, or interrupt the company's own manufacturing operations.

A potential new pandemic or mutations could lead to new and more extensive restrictions and uncertainty in the global market economy, causing impacts which are difficult to predict.

Information systems may be subject to external cyber security threats. The company aims to protect itself against such threats by means of technical solutions and by increasing the security competence of the personnel. Increased geopolitical tensions have increased the likelihood of cyber attacks. Such attacks can cause local and global disruptions that have an adverse impact on the activities of the company or its customers or suppliers.

The company may also be targeted by illegal activities and attempted fraud, which could have a significant effect on the financial result. The Group strives to minimize these risks by continuing to develop good governance practices and increasing the security competence of its personnel.

Data leaks involving sensitive employee or customer data may lead to reputational damage or significant financial repercussions. A data leak could be caused by, for example, cyber crime, ransomware, data theft, fraud, misconduct or inadvertent mistakes by our employees.

10.4. FINANCIAL RISKS

As the company expands into new markets, currency risk may increase, particularly with regard to the US dollar. The risk is partly offset by raw material and component purchases denominated in the US dollar and the Chinese renminbi, as well as the geographical diversification of production. Exchange rate fluctuations may affect the company's net sales, product costs and profit. The most significant exposures are related to the US dollar and the Chinese renminbi relative to the euro. Short-term currency risks are managed by means of forward exchange contracts and options.

The risk of obsolete inventories may increase due to higher safety stock levels and occasional disruptions in the availability of materials. The increase in working capital may reduce the financial reserves available to the company. Problems with the availability of raw materials and components may complicate manufacturing operations and cause delays in deliveries, leading to increased working capital and a higher liquidity risk for the company.

Although the company's financial position is stable and its debt has decreased, the company may face the need to increase its debt financing for various reasons. It is difficult to predict the costs and availability of potential new debt financing in advance.

Potential changes in interest rates could have an effect on the company's financial expenses to the extent that interest-bearing liabilities have not been hedged.

The company may be exposed to risks related to its customers' liquidity and payment behavior, which may affect the company's cash flow or lead to credit losses. Significant changes in the financial or tax regulations of different countries, or changes in the interpretation of such regulations, may also have an impact on Teleste's financial performance, liquidity or cash flow.

More detailed information on financial risks is published in the notes to the financial statements 2025.

11. LEGAL PROCEEDINGS AND JUDICIAL PROCEDURES

In 2023, Teleste's subsidiary in Germany has filed a claim for damages related to a project which the customer terminated without a valid reason in Teleste's opinion. The deliveries of the terminated project included passenger information systems to a group of local public transport operators. The claim proceedings are still ongoing. Teleste estimates that the legal proceedings will not have any significant financial impact on the Group's operations.

At the end of the period under review, there were no other legal proceedings or judicial procedures pending that would have had any essential significance to the Group's operations.

According to the authorization, the Board of Directors may acquire 1,200,000 of the company's own shares otherwise than in proportion to the holdings of the shareholders with unrestricted equity through trading on the regulated market organized by Nasdaq Helsinki Ltd at the market price at the time of the purchase.

The share purchase authorization is valid for eighteen (18) months from the date of the resolution of the Annual General Meeting. The authorization overrides any previous authorizations to purchase the company's own shares.

The new shares may be issued and the company's own shares held by the company may be conveyed either against payment or for free. New shares may be issued and the company's own shares held by the company may be conveyed to the company's shareholders in proportion to their current shareholdings in the company, or by waiving the shareholder's pre-emption right, through a directed share issue if the company has a weighty financial reason to do so. The new shares may also be issued in a free share issue to the company itself.

The authorizations are valid for eighteen (18) months from the resolution of the Annual General Meeting. The authorizations override any previous authorizations to decide on issuances of new shares and on granting stock option rights or other special rights entitling to shares.

16. OPERATING ENVIRONMENT IN 2025

BROADBAND NETWORKS

Demand for broadband technology returned to growth in 2025. Growth has been driven by intensified competition among network operators to provide fast, reliable broadband connectivity to households and businesses using multiple access technologies, even as operators' own revenues have remained under pressure.

DOCSIS 4.0 -based intelligent access network technologies enable highly competitive internet services by combining fiber and cable technologies within the same network architecture. At the same time, the importance of software-driven intelligence, telemetry and remote management capabilities has increased significantly, supporting more reliable broadband services while reducing network build and maintenance costs.

Investments in DOCSIS 4.0 technology began in North America during 2024. In Europe, investments started during 2025 in parts of the market. The North American cable market is significantly larger than the European market.

In May 2025, Charter Communications and Cox Communications announced a proposed merger. Once completed, the transaction would create the largest fixed broadband and pay-TV operator in North America. The transaction is subject to customary regulatory approvals and is expected to close by mid-2026. The planned merger has temporarily impacted network investment activity by our customer (the

Shares and shareholders

selling party) from the second half of 2025 onward, as pre-closing investments have been optimized during the process.

U.S. import tariffs and shifting trade policies continue to create uncertainty in the market. However, it is not expected to materially impact customers' investment plans or the longer-term growth of the North American network market.

Teleste's DOCSIS 4.0 technology delivery volumes increased significantly during 2025. North America's share of Teleste's revenue rose to 30% in 2025, and we expect this share to continue increasing in 2026. At year-end 2025, the Company served more than 20 network operator customers in North America. We initiated production ramp-up activities in Mexico during the third quarter of 2025, and the first products are expected to be manufactured at the Mexico facility during the first quarter of 2026.

PUBLIC SAFETY AND MOBILITY

Urbanization, the expansion of sustainable public transportation solutions, and the integration of digital systems into everyday life are creating a strong long-term growth foundation for passenger information solutions. At the same time, ensuring the security of critical infrastructure through intelligent digital technologies is opening up new growth opportunities in the market.

The operating environment has become more favorable and predictable, supporting steady growth. The business typically consists of end-to-end projects that include development, delivery and lifecycle support phases. Publicly funded projects are inherently cost-conscious, which places high requirements on suppliers in terms of efficiency and competitiveness.

The importance of real-time software solutions has continued to increase. Passenger information systems are becoming

more intelligent, and software capabilities have become a key differentiator.

Solutions and services aimed at improving the passenger experience are increasingly influencing customer decision-making. In parallel, lifecycle management of systems, ensuring cybersecurity, service and maintenance, and building long-term partnerships around these capabilities are becoming increasingly important parts of the business.

The market is seeing growing demand for intelligent, interoperable solutions that enhance the security of public and critical infrastructure. Alongside traditional video surveillance solutions, real-time mobile surveillance systems —both mobile and stationary —have emerged, together with integrated situational awareness platforms that enable unified management and analysis of video and other data streams.

During 2025, Teleste expanded its customer base across both rolling stock manufacturers and public transport operators. Service and maintenance business is generating an increasing stream of recurring revenue alongside new project deliveries. Investments in software development, artificial intelligence and cybersecurity increased, and this trend is expected to continue in 2026.

The markets for passenger information and security solutions in public transport and critical infrastructure offer attractive opportunities, and Teleste's strong position supports sustainable growth and continued development.

17. PROPOSAL OF THE BOARD OF DIRECTORS ON THE USE OF THE PROFIT SHOWN ON THE BALANCE SHEET

The Board of Directors proposes to the Annual General Meeting that a total dividend of up to EUR 0.08 (0.03) per outstanding share will

be distributed from the distributable funds for the financial year ended 31 December 2025. In addition, the Board proposes that the dividend will be paid in two instalments, the first during the third quarter of 2026 and the second at the latest during the first quarter of 2027.

18. OUTLOOK FOR THE YEAR 2026

Teleste estimates that Net sales for 2026 will be in the range of 140 to 160 million euros and adjusted Operating profit in the range of 7 to 10 million euros. Profit is expected to be weighted toward the second half of the year. Material changes in the operating environment, including geopolitical tensions, changes in trade policies, and the development of the US dollar exchange rate can create uncertainty for parts of the business.

19. EVENTS AFTER THE REVIEW PERIOD

On January 12, 2026, the Company announced the proposals of the Shareholders' Nomination Board to the Annual General Meeting. The Company's Board of Directors will convene the Annual General Meeting separately.

On January 20, 2026, the Company announced a four-year framework agreement with Infrabel, a Belgian state-owned company, for the delivery of station displays to the Belgian railways.

On January 29, 2026, the Company announced that it had signed a multi-year framework agreement with France's national railway operator (SNCF) for the delivery of station displays to the French railways.

Teleste maintains project-specific and event-specific insider lists as necessary. Project-specific insider lists include the persons who work for Teleste under an employment contract or other agreement and receive insider information concerning an individual project, as well as any other persons to whom Teleste discloses insider information concerning an individual project. 'Project' refers to an identifiable arrangement or set of procedures which is being prepared at Teleste in strict confidence and which, when disclosed, could materially affect the value of Teleste's financial instrument. The CEO evaluates each case to determine whether a set of procedures or an arrangement is considered as a project.

Persons discharging managerial responsibilities at Teleste with the obligation to notify are the Board members, the CEO, the CFO, the SVP in charge of the Broadband Networks

business unit and the SVP in charge of the Public Safety and Mobility business unit. They and persons closely associated with them shall notify Teleste and the Finnish Financial Supervisory Authority of any transactions they conduct in Teleste's financial instruments, which Teleste discloses in the form of separate stock exchange releases. It is recommended for persons discharging managerial responsibilities at Teleste to time their trading activities involving financial instruments issued by Teleste in such a manner that as accurate as possible information affecting the value of the share is available in the market.

The persons discharging managerial responsibilities at Teleste are not permitted, on their own account or on behalf of others, directly or indirectly, to trade in financial instruments issued by Teleste during the "closed window" period, that is, for thirty (30) days prior to the publication of an interim report and financial statement release. Teleste has expanded the closed window to also apply to persons participating in the preparation of interim reports and/or financial statement releases and persons who, due to the nature of their responsibilities, have access to the content of the reports prior to their publication. Such persons are subject to the same closed window of thirty (30) days.

Teleste's insider administration supervises compliance with the insider guidelines and maintains insider lists as well as a list of persons discharging managerial responsibilities and persons closely associated with them. Teleste's Senior Legal Counsel is in charge of insider issues.

Teleste has a whistleblowing channel that provides Teleste's employees and third parties with the opportunity to report concerns of potential misconduct in Teleste's business operations or other functions related to the company. The whistleblowing channel can also be used for reporting suspected violations of the rules and regulations concerning the financial markets.

Related party transactions, internal control, risk management and internal auditing

Related party transactions

Teleste assesses and monitors related party transactions in accordance with the Finnish Corporate Governance Code and Teleste's internal guidelines. Teleste strives to ensure that any conflicts of interest are taken into account in the decision-making process. The main rule is that all related party transactions always relate to Teleste's normal business, are in line with the company's purpose and are conducted on normal commercial terms. The Board of Directors decides on related party transactions that are not conducted in the ordinary course of business or are not implemented under arm's-length terms.

Teleste's legal department is responsible for the identification of related parties and maintains up-to-date records of related parties for the purpose of identifying related party transactions. Information on related party transactions is provided in the notes of the financial statements.

Internal control

Teleste's internal control is designed to support the implementation of the strategy and to ensure the achievement of the specified goals, compliance with the regulations as well as the reliability and accuracy of financial reporting. Internal control is based on Teleste's values and corporate culture, as well as Group- and operational-level structures and processes that support each other. The management of the Group and the business units are responsible for internal control as part of their normal managerial duties, while the Board evaluates and monitors the effectiveness of internal control. In each of the two business units, the management of the business unit, supported by Teleste's centralized business controller function, is responsible for compliance with the principles of internal control on all levels of the units.

Risk management

Teleste's risk management policy defines the objective of risk management as the achievement of strategic objectives. The principles and objectives of the Group's risk management are subject to approval by Teleste's Board of Directors. Risk management aims to ensure the achievement of business goals, so that any material risks affecting business operations and posing a threat to the achievement of goals are identified and continuously monitored and evaluated. The company has risk management methods in place to prevent the materialization of risks. In addition, insurance is used to cover financial risks and other risks that are reasonably insurable. Regular, cost-efficient evaluation and management of risks are emphasized in Teleste's risk management policy. Risk management supports the business operations and generates added value that promotes decision-making and goal-setting by the management in charge of business operations. Monthly reporting constitutes part of the internal control and risk management system. In particular, it is used for the monitoring of the development of orders received, order backlog, deliveries, net sales, profitability, trade receivables, working capital and cash flow and, consequently, the development of Teleste Group's performance. The Board of Directors reviews essential business risks and their management quarterly and whenever necessary. Risk management constitutes an integral part of the strategic and operational activities of the business units and Group functions. Risks are reported to the Board on a regular basis.

Teleste's risk management system covers the following risk categories: strategic risks, operational risks, financial risks and hazard risks. For each identified risk, the Leadership Team confirms a risk owner who is responsible for risk assessment, selecting the risk management strategy, planning risk management actions and assigning responsibilities for them, and risk monitoring.

Internal auditing

Internal auditing includes evaluating the efficiency of processes related to risk management, supervision, management, administration and selected functions, as well as making proposals for their improvement. Internal auditing functions under the authority of the Board's Audit Committee. The CEO or a director appointed by the CEO is responsible for the implementation of the auditing, and the expertise of bodies external to the auditing unit is used where needed. In addition, internal auditing may carry out special tasks assigned by the Audit Committee. Internal auditing covers all the organizational levels. Internal auditing also coordinates priorities together with the external auditor.

Key features of the internal control and risk management systems related to the financial reporting process

The internal control and risk management of the financial reporting process are based on the general principles of internal control and risk management described above as well as the auditor's recommendations concerning best practices related to reporting processes and the control environment. The CFO is responsible for the systems of internal control and risk management related to the financial reporting process.

The internal control of the financial reporting process is established by describing the reporting process and specifying the control points on the basis of a risk assessment. The controls cover the entire reporting process from accounting by subsidiaries to monthly, quarterly and annual reporting. Controls are built into reporting systems, or controls may involve balancing, inspections carried out by the management, or specified procedures or policies. The CFO is responsible for ensuring that there is a designated person responsible for the implementation and efficiency of each control. The Group Accounting Manual specifies the standards for financial reporting. Financial reports to be published are reviewed by the Leadership Team, the Audit Committee and the Board of Directors prior to their publication.

The auditor elected by Teleste's Annual General Meeting audits the consolidated financial statements and parent company financial statements and reviews the stock exchange releases issued on interim reports and the financial statements. The Group's largest subsidiaries conduct a local audit.

Sustainability Report

Corporate responsibility is an important part of the company's operations and the product and service offering. The company's products and services promote safety, security, environmentally friendly and efficient public transport as well as energy-efficient digital communications solutions.

The company's management has assessed the materiality of different aspects of corporate responsibility with respect to the company's stakeholders and business operations. By taking all facets of corporate responsibility into consideration, the company wants to ensure that its responsibility-related measures enable a sustainable future for the generations to come. At the same time, the company responds to the expectations of customers, investors and other stakeholders, and ensures its position as an attractive employer.

The Corporate Sustainability Reporting Directive (CSRD) is the European Union's regulatory framework created to improve and standardize corporate sustainability reporting. It entered into effect starting from the financial period 2024. In March 2025, Teleste Corporation published its first sustainability report in accordance with European Sustainability Reporting Standards (ESRS) under the Corporate Sustainability Reporting Directive (CSRD) and in compliance with the provisions of chapter 7 of the Finnish Accounting Act, on the financial period 2024.

The Omnibus package, which was under consideration by the EU at the time of publication of the financial statements, includes amendments to several directives, including the Corporate Sustainability Reporting Directive (CSRD). The company will monitor legislative developments, assess their impacts and make decisions regarding the form of its sustainability and taxonomy reporting once the changes have been confirmed.

In addition to sustainability reporting, the impact of the company's sustainability efforts has been monitored by means of the international EcoVadis sustainability assessment for several years now. Teleste has achieved a Gold Medal in the assessment, which is only awarded to the top 5% of the audited companies. In the EcoVadis assessment, companies are benchmarked against other companies, which means that maintaining the Gold Medal rating requires continuous development and progress. In 2024, the company made a commitment to the Science Based Targets initiative (SBTi) to achieve a clear path towards the emissions targets stipulated by the Paris Agreement. The process of obtaining approval for Teleste's SBTi targets is under way. In 2023, the company also made a commitment to the UN Sustainable Development Goals and the UN Global Compact, which is based on the SDGs and is the world's largest corporate responsibility initiative. Together, EcoVadis, the UN Global Compact and the EU's reporting obligations support the continuous development of sustainability efforts.

In the next section, we present our sustainability report for the financial period 2025, as in the previous year. The report contains verified information on the company's material sustainability themes.

BASIS FOR PREPARATION

GENERAL BASIS FOR PREPARATION OF THE SUSTAINABILITY STATEMENT (BP-1)

Teleste Corporation and its subsidiaries form a group ("Teleste", "the Group", "the company") consisting of two business segments: Broadband Networks and Public Safety and Mobility. The business segments have been incorporated as subsidiaries that are 100% owned by Teleste Corporation. The parent company also has Group functions that support the operations of the business units by providing various administrative and other services.

The sustainability report has been prepared on a consolidated basis. The scope of the report is consistent with the scope of the consolidated financial statements of Teleste Corporation. The report has been prepared in accordance with the provisions of chapter 7 of the Finnish Accounting Act. The report describes the impacts, risks and opportunities related to Teleste's own operations and value chain. The value chain is described in more detail in the section "Strategy, business model and value chain" (SBM-1). No material information has been omitted from the sustainability report on the basis of the information corresponding to intellectual property, know-how or the results of innovation.¹

The reported sustainability aspects and indicators are based on Teleste's double materiality assessment, which was first conducted in the financial year 2024 and subsequently updated during the financial year 2025. The material reporting requirements from the perspective of the company's operations, products and stakeholders have been selected on the basis of the materiality assessment. The material impacts, risks and opportunities and aspects to be reported, which were determined on the basis of the double materiality assessment, were approved by the company's Board of Directors on 4 November 2025. This consolidated sustainability report is Teleste's second sustainability report in accordance with the ESRS.²

The reporting period is consistent with the financial reporting period. For this report, the financial year is 1 January 2025-31 December 2025.³ The materiality assessment and its results are discussed in more detail in the section "Description of the processes to identify and assess material impacts, risks and opportunities" (IRO-1).

DISCLOSURES IN RELATION TO SPECIFIC CIRCUMSTANCES (BP-2)

During the period under review, there were no circumstances exceptional for the business that would have had a significant effect on the content of the company's sustainability reporting.⁴

Time horizons

The time horizons defined in the ESRS are, as a rule, used in the report. Short-term refers to the reporting period, medium-term refers to the period from the end of the reporting period up to five years, and long-term refers to a time horizon of more than five years. Teleste deviates from these definitions in the climate risk assessment and resilience analysis, for which the time horizons were defined as follows: in the short-term time horizon, the risk was estimated to be realized by 2026, in the medium-term time horizon by 2030, and in the long-term time horizon by 2050. For climate risks, the decision was made to keep the time horizons consistent with the time horizons used in Teleste's climate targets.⁵

The report includes all ESRS standards identified as material in the double materiality assessment: ESRS 2, E1, E5, S1 and G1. Transitional provisions have been applied on a standard-specific basis for data points that are subject to transitional provisions. Transitional provisions have been applied in the following sections:

  • ESRS 2: SBM-1 40 b,c and SBM-3 48e
  • ESRS E1: E1-9
  • ESRS E5: E5-6
  • ESRS S1: S1-11, S1-15⁶

Value chain estimation, sources of estimation and outcome uncertainty

Teleste's reporting mainly includes metrics related to the company's own operations. However, the company's emissions calculation and related metrics in section E1 and the share of recycled aluminum in Teleste's products in section 2 also contain information related to the value chain. As is typical, the scope 3 emission category, which describes the emissions of the value chain, includes estimates in particular. Supplier-specific emissions data and factors have been used in the calculation of transport emissions whenever they are available, thus aiming for the most

accurate possible calculation result. The company partly utilizes obtained emissions data and calculations based on metric ton-kilometers, which include assumptions and uncertainties. These are described in section E1 in the paragraph "Metrics and targets (E1-4)". There are also uncertainties associated with determining the proportion of recycled aluminum, and these are described in more detail in section E5 in the paragraph "Resources inflows, including resource use (E5-4)". Teleste aims to continuously improve the accuracy and reliability of the data. The company has not reported any quantitative metrics or monetary amounts that are subject to a high level of measurement uncertainty. $^{8}$

Changes in preparation or presentation of sustainability information

Two new material sustainability risks were identified in the double materiality assessment. The risks are related to cyber security and the topic of corruption and bribery. These risks are reported in the section "Business conduct" (ESRS G1). Teleste's scope 1 emissions calculations have been updated to include fuel consumption data, which was missing from the previous calculations. This affects the figures presented in section E1 of the report in paragraphs "Energy consumption and mix" (E1-5) and "Gross Scopes 1, 2, 3 and Total GHG emissions" (E1-6). The scope 1 calculations have also been supplemented with regard to refrigerants, which is also reflected in a minor change in the outcomes related to the company's emission reduction targets in the section "Metrics and targets" (E1-4). The changes to the comparison data have not been verified.

Reporting errors in prior periods

A minor correction has been made to the weight of secondary reused or recycled components, secondary intermediary products and secondary materials (kg and %) presented in Table 15 in section E5-4 for the financial year 2024. This is due to the recycling rate applied for packaging material in the NET business, which was reported as 80% in 2024, when the actual share of recycled packaging material was 21%. However, the correction did not have a significant effect on the percentage of secondary reused or recycled components, secondary intermediary products and secondary materials presented in Table 15. The changes to the comparison data have not been verified. $^{9}$

GOVERNANCE

THE ROLE OF THE ADMINISTRATIVE, MANAGEMENT AND SUPERVISORY BODIES (GOV-1)

The Board of Directors that convened after Teleste's AGM on 23 April 2025 decided on the following Audit Committee composition: Mirel Leino-Haltia (Chair), Jussi Himanen and Vesa Korpimies. Effective from 23 April 2025, the Personnel and Remuneration Committee has consisted of Kai Telanne (Chair), Timo Luukkainen and Anni Ronkainen.

On 31 December 2025, the Group's Leadership Team consisted of eight members including the CEO, to whom the members of the Leadership Team report. Esa Harju, Ulf Andersson, Pasi Järvenpää, Linda Kallas, Mervi Kerkelä-Hiltunen, Esa Korolainen, Valerian Sand and Tuomas Vanne were members of the Leadership Team for the entire financial year. All members of the Leadership Team, with the exception of the CEO, are employed by the company. The gender distribution of the Leadership Team (ratio of female to male members) was 0.33. $^{12}$

The governance bodies responsible for the administration and operations of Teleste Corporation are the Annual General Meeting, the Board of Directors and the CEO, assisted by the Shareholders' Nomination Board, the Board of Directors' Audit Committee and Personnel and Remuneration Committee, and the Leadership Team, which is led by the CEO. The governance policies are defined in the rules of procedure of each governance body. $^{13}$

Sustainability-related topics are addressed in accordance with Teleste's sustainability management model. Traditionally, sustainability efforts have been focused on the management of risks and impacts. Following the double materiality assessment, opportunities will also be incorporated into the process. In 2025, the assessment of sustainability-related risks and opportunities was integrated more closely into the Group-level process for managing risks and opportunities. $^{14}$

Teleste's sustainability management model:

Board of Directors

Teleste's Board of Directors is the highest decision-making body in strategic matters related to sustainability. The Board of Directors confirms the material sustainability themes and approves the key policies and strategy, as well as the company's double materiality assessment and sustainability report. $^{15}$

The Audit Committee of the Board of Directors is responsible for monitoring and evaluating the company's sustainability reporting. The Personnel and Remuneration Committee discusses and prepares matters related to the remuneration of the company's management (CEO and Leadership Team), including sustainability-related targets as part of the management's remuneration. The Board of Directors and the Leadership Team have access to the expertise of sustainability experts employed by the company. $^{16}$

CEO and Leadership Team

The CEO is responsible for the Group's implementation of the sustainability targets confirmed by the Board of Directors. The CEO reports to the Board of Directors on material sustainability-related impacts, risks and opportunities. The CEO and the Group's Leadership Team addresses the Group's sustainability-related impacts, risks and opportunities, oversees the company's sustainability efforts and provides the necessary resources for sustainability efforts.

Vice President, Strategy, Communications & Sustainability is a member of the Leadership Team and is in charge of the company's sustainability efforts and the sustainability and quality team. Progress towards sustainability targets is monitored by both the Leadership Team and the sustainability steering group.¹⁷

Sustainability steering group

The sustainability steering group acts as a preparatory body for the decision-making of the Leadership Team. It includes representatives from the Leadership Team and the sustainability and quality team, as well as the Senior Legal Counsel.¹⁸

Sustainability and quality team

The sustainability and quality team coordinates Teleste's sustainability efforts. The team works together with a network comprised of representatives of various functions and business units. The business units and Group functions are responsible for the implementation of sustainability efforts and ensuring that the company meets all of its commitments.¹⁹

The material impacts, risks and opportunities being focused on the themes of climate and circular economy has been taken into account in the allocation of resources to sustainability functions. Actions and expertise related to own workforce and social responsibility have been concentrated in the HR department. Governance-related expertise is concentrated in the legal department. The HR department maintains a competence matrix, which is presented to the executive management on a regular basis. Competence related to sustainability is addressed, based on the executive management's report, as part of operational processes related to competence, which are also subject to approval by the governance bodies.²⁰

INFORMATION PROVIDED TO AND SUSTAINABILITY MATTERS ADDRESSED BY THE UNDERTAKING'S ADMINISTRATIVE, MANAGEMENT AND SUPERVISORY BODIES (GOV-2)

Sustainability topics, including actions and targets related to the minimization of impacts, are addressed by several different functions in accordance with the sustainability management model. Teleste's environmental and climate targets are an integral part of the company's ISO14001-certified environmental management system, the targets of which are monitored by the Leadership Team in annual management reviews.

As a rule, the sustainability steering group meets monthly. The steering group addresses current measures and targets related to both sustainability and quality, and sets guidelines for practical sustainability efforts.

Sustainability matters, including targets, impacts, risks and opportunities, are regular items on the Leadership Team's agenda.

The due diligence process involves many different functions. The process is not addressed as a separate set of measures — instead, the different parts of the process are addressed as necessary as part of the measures taken by each function.

The sustainability steering group acts as a preparatory body for the administrative, management and supervisory bodies in sustainability matters. Targets and actions related to social responsibility are primarily addressed as part of HR matters. In connection with the double materiality assessment, information was provided to the administrative and supervisory bodies on both the assessment process itself and the material impacts, risks and opportunities identified on the basis of the process. In accordance with their roles, the executive management presents sustainability-related matters to the Audit Committee, which issues its recommendations before approval by the Board of Directors. Sustainability matters are on the agenda of the Board of Directors at least annually.

Although sustainability has already been on the agenda of the management and the sustainability steering group previously, the company deemed it necessary to clarify the management model. A clearer description of the sustainability management model was created in 2024. The management model describes the responsibilities and division of duties of different organizations and working groups with regard to sustainability matters. Top management, i.e. the Board of Directors, approves the most important sustainability targets and the sustainability report.

In 2025, sustainability — especially changes in EU legislation and the double materiality assessment — were also on the agenda of the Board of Directors and the Audit Committee. Measures related to structuring the company's sustainability efforts are continuing, and the goal is to embed sustainability even more systematically into the company's existing operating practices and guidelines. This is supported by the company's organizational structure, where sustainability and quality are part of the same organization at the Group level.

Teleste's previous sustainability impact assessment process was based on a materiality assessment that is simpler than the double materiality assessment, and the sustainability priorities have been defined on the basis of the double materiality assessment. Sustainability, including ethical operating practices, has been taken into account in the background work for the strategy. The sustainability steering group participates in determining sustainability targets and priorities.

The management of sustainability-related risks and opportunities was integrated into the Group-level risk and opportunity management process in connection with the development of the risk and opportunity process. The Group-level risk and opportunity management process provides inputs for the strategy process.

In the Leadership Team, the Senior Vice President, Strategy, Communications & Sustainability is in charge of sustainability. In accordance with her role, she brings the sustainability perspective to the Leadership Team's work.

The following sustainability-related topics, among others, were addressed in the meetings of the Leadership Team during the financial year 2025:

  • Updates to Group policies
  • Employee well-being and development
  • Occupational safety
  • Sustainability reporting
  • Double materiality assessment process and its outcomes
  • Environmental and climate targets, SBTi commitment²¹

INTEGRATION OF SUSTAINABILITY-RELATED PERFORMANCE IN INCENTIVE SCHEMES (GOV-3)

Teleste has two types of incentive schemes in place: a long-term incentive scheme and a short-term incentive scheme. The metrics of both schemes consist of both financial and operational metrics. The targets established for the Leadership Team's variable remuneration components include a sustainability-related metric. The company uses the results of the external EcoVadis sustainability assessment as a metric. The assessment takes into account climate- and human rights-related matters, for example. The metric assesses the sustainability and social responsibility of companies based on four key themes: Environment, Labor and Human Rights, Ethics, and Sustainable Procurement.

From the EcoVadis rating used as a metric, it is not possible to separately distinguish Teleste's performance relating to the company's climate targets. The EcoVadis assessment process helps Teleste manage ESG risk and compliance, achieve its sustainability targets and make a broad impact by steering the improvement of the sustainability performance of the company and its value chain.[22]

The conditions of Teleste's incentive schemes concerning the variable remuneration component for the company's personnel, including the management, are approved by the Board of Directors. Sustainability-related metrics have not been incorporated into the remuneration of the company's Board of Directors or other governance bodies. The company's Remuneration Policy and related guidelines do not include a separate requirement for the company's personnel (including

the Leadership Team) or the administrative, management and supervisory bodies regarding the integration of sustainability metrics in the company's various incentive schemes.[23]

RISK MANAGEMENT AND INTERNAL CONTROLS OVER SUSTAINABILITY REPORTING (GOV-5)

Teleste has a robust risk management policy and process for the Group. The sustainability-related risks identified as material in the double materiality assessment and the management of sustainability risks were integrated into Teleste Group's risk management process in 2025. Sustainability-related

risk management and the development of internal control processes will continue in the coming years.

Risk management is an integral part of decision-making, management and day-to-day operations in Teleste's business units and Group functions (OLS, R&D, IT, finance and control, HR, legal). Risk management is applied at the strategic, operational, business program and project levels. Sustainability-related risk management has been integrated into the Group's approach.

Risk owners determine the risk management method as part of risk assessment. The risk management methods are as follows:

  • Risk avoidance, which is aimed at the elimination of the risk or the company's withdrawal from, or non-participation in, the risk. This also includes the avoidance of actions that could cause the risk in question.
  • Risk mitigation, which is aimed at optimizing or mitigating the risk. Risk mitigation means reducing the severity or probability of loss.
  • Risk sharing, which is aimed at transferring, externalizing or insuring against the risk.
  • Risk acceptance or retention, which means accepting the loss or benefit arising from the realization of the risk.

When the chosen risk management method is risk mitigation or risk sharing, the risk owner designates a person responsible for the risk management actions. The owner of the risk management actions plans the appropriate measures to achieve an acceptable balance between the impact of the potential risk and business objectives. The risk owner must integrate the risk management measures into the relevant business processes and evaluate the effectiveness of the actions in question.

Teleste's risk management policy and process also apply to sustainability risks. The owner of risk management actions is responsible for the implementation and monitoring of the risk management actions.

The Chief Financial Officer (CFO) is responsible for preparing risk reviews and reporting key risks to Teleste's Audit Committee and Teleste's Board of Directors twice a year, in accordance with the annual schedule of the Audit Committee and the Board of Directors. Sustainability risks are included in risk reviews.²⁵

Business model and value chain

Teleste is an international technology company that offers products and services related to broadband networks, video security and passenger information solutions. The company's value chain covers activities from the upstream value chain to the downstream value chain and includes both the company's own operations and key supplier and customer relationships.

In the upstream value chain, Teleste purchases components, parts and services from suppliers. These include electronic components and transport, among other things. The company works closely with its suppliers to ensure product quality, availability and sustainable operating practices.

Teleste's own operations cover product development, the procurement of components, manufacturing, testing and deliveries to customers. Manufacturing takes place mainly in Finland, where the products are assembled and tested. These activities play a key role in the company's value creation and ensuring customer satisfaction.

The downstream value chain includes product delivery, installation, after-sales services, maintenance and product end-of-life management. Teleste also offers installation and maintenance services to its customers.

Customers benefit from Teleste's innovative and reliable solutions that improve the performance and reliability of telecommunications networks, the smoothness of public transport and the security of society. Investors expect stable financial performance and dividend distribution. Other stakeholders value Teleste's responsible business and commitment to sustainability. Teleste controls a significant part of its value chain internally, which improves efficiency and customer satisfaction.

The double materiality assessment covered the impacts, risks and opportunities of the entire value chain and business operations. The impacts, risks or opportunities related to Teleste's own operations were not disaggregated by business unit. The identified material impacts, risks and opportunities are mainly related to Teleste's entire business. The impacts related to the in-use energy consumption of products are particularly evident in the downstream value chain.³⁰

INTERESTS AND VIEWS OF STAKEHOLDERS (SBM-2)

Teleste engages in regular interaction with key stakeholders and develops its operations based on stakeholder feedback. The views of stakeholders were utilized in the materiality assessment carried out in 2024, on the basis of which Teleste confirmed the sustainability themes that are material to the company's operations. The themes constitute the focal points of Teleste's sustainability efforts. The materiality assessment is discussed in more detail in the section Material sustainability-related impacts, risks and opportunities.

The purpose of stakeholder engagement is to communicate Teleste's strategy, business, targets, products and services to stakeholders and, at the same time, obtain information about the stakeholders' thoughts and wishes concerning Teleste's operations. The feedback is reviewed as part of the normal work of the Leadership Team, and the company aims to take stakeholder perspectives into account as quickly as possible in day-to-day operations.

that lead to larger, strategy-level changes are used as inputs in the strategy process.

Teleste's most significant stakeholders are customers, shareholders and investors, suppliers and the company's personnel. The perspectives and wishes of stakeholders are surveyed in various ways. With regard to investors and shareholders, the most important communication channels are external investor reporting, the separate investor pages on the company's website, the Annual General Meeting and various investor meetings. With the exception of public reports, all of the aforementioned communication channels are bi-directional. They provide stakeholder representatives with the opportunity to express their opinions and ask questions. Some of the aforementioned communication channels also serve as communication channels for customers. Information on customer wishes, ideas and requirements is obtained through various events and customer meetings.

The opinions of the personnel are listened to as part of day-to-day operations and supervisory work. The annual Success and Growth Discussions also provide a good opportunity to take the employees' opinions into consideration. Teleste also conducts regular pulse surveys among the personnel. The employees also have the opportunity to comment on the assessment of risks and opportunities.

Cooperation with suppliers mainly takes place in supplier meetings. Information is obtained from suppliers on, for example, new solutions that the product development and procurement organization can use in the design of existing and new products and the procurement of related materials.

Based on the stakeholder interviews and surveys conducted as part of the materiality assessment process, Teleste's most significant environmental impacts are related to energy consumption and the energy efficiency of products. The recyclability of materials was also highlighted as a key issue. With regard to social responsibility, the well-being of Teleste's employees was considered important and material also from the perspective of attracting and retaining talent. The positive impacts of the community from a broader perspective include, for example, improving remote work opportunities and supporting public transport and security. With regard to governance practices, the Nordic management style was highlighted as a positive aspect. The recent improvement in the Supplier Code of Conduct was recognized as a positive development. Information security was also mentioned, and improving documentation was highlighted as a development area.[31]

Among the stakeholders, the importance of sustainability has been highlighted by customers in particular. To respond to this wish, Teleste has developed its sustainability-related practices and sought to integrate sustainability into the processes of all organizations. The materiality analysis provided Teleste with good tools for developing its sustainability efforts. The company aims to integrate sustainability even more closely into its strategy. The company expects that increasing sustainability measures to change the stakeholder's sustainability perception of Teleste in the medium term.

Teleste's sustainability management model is described in more detail in the paragraph "The role of the administrative, management and supervisory bodies (GOV-1)". The views of stakeholders are highlighted in accordance with the management model and as described above, as part of the normal work of the Leadership Team. The views of the company's key stakeholders were surveyed as part of the double materiality assessment carried out in 2024. The key perspectives obtained from stakeholders served as inputs for the strategy work.[32]

MATERIAL SUSTAINABILITY-RELATED IMPACTS, RISKS AND OPPORTUNITIES (SBM-3)

Material sustainability-related impacts, risks and opportunities have been determined by means of a double materiality assessment. The aim was to identify and assess the impacts, risks and opportunities that may be of relevance to the implementation of the company's strategy in the short and long term, while simultaneously identifying and assessing the impacts of the company's business activities on society and the environment. Teleste's first double materiality assessment was carried out in 2024. The assessment was updated in 2025.

The most material impacts, risks and opportunities are described in the tables below for each ESRS standard. They are also discussed under each individual topic-specific standard. This report focuses on the topics covered by the ESRS. When the double materiality assessment was updated in 2025, information security was identified as a new material sustainability risk. Information security is an entity-specific topic that is addressed in section ESRS G1, Governance and corporate culture.[33]

The negative impacts related to climate change and the circular economy described above are related to carbon dioxide emissions and the consumption of materials. They are typical of the manufacturing industry. The positive impacts related to climate change and the circular economy, in turn, are directly linked to Teleste's operations and strategy. With regard to Teleste's own workforce, the positive impacts and the identified negative impact are related to Teleste's operating model and strategy. The positive impacts related to governance are related to Teleste's operating model and strategy. All of the impacts identified as material have been assessed over the medium term.

The identified material impacts are mainly related to Teleste's own operations and operating model. However, the impacts related to climate change and the circular economy also include impacts related to the value chain, such as emissions caused by the in-use energy consumption of products, and energy-efficient products. The governance-related impacts extend not only to Teleste's own operations but also to the value chain through business relationships.[35]

The company's most material risks and opportunities were also determined on the basis of the materiality assessment. The material risks and opportunities are described in the tables below for each ESRS standard. All of the opportunities identified as significant in the double materiality assessment are linked to climate change, while the identified material risks relate to climate change, circular economy, own workforce and governance.

The risks identified as material in relation to climate change were analyzed in more detail in the resilience analysis. In connection with this, the risks were grouped into larger sets to improve understandability. The results of the resilience analysis are described in more detail in section E1 Climate change. With regard to many risks, the impacts on Teleste's business and the measures to prepare for the risk are quite similar in practice.³⁶

All impacts identified as material are estimated to occur over a period of 1–5 years.³⁷ The time horizon of the risks is described in table 2.

Table 3 describes the physical and transition opportunities related to climate change. No material opportunities were identified under the other ESRS topics.

The material sustainability impacts and risks are largely taken into account in the company's sustainability efforts, the background factors of the strategy, the business model and decision-making. Teleste's sustainability efforts are the subject of continuous development and, in the future, the company will pay increasing attention to the management of sustainability-related opportunities in particular. Teleste has no significant sustainability-related risks that would currently affect the next annual financial reporting.

Sustainability-related risks and opportunities are taken into account in the Group-level risk and opportunity management process. Teleste's strategy and business model are adapted as necessary to mitigate risks and take advantage of opportunities. The risk and opportunity management process provides inputs for strategy work.

The resilience of the strategy and business model with regard to the climate-related risks described above has been analyzed in connection with the climate resilience analysis. The results of the analysis are described in table 8 "Resilience analysis". Based on the analysis, Teleste's strategic measures, technological innovation capacity, strong in-house product development, manufacturing expertise and cooperation with suppliers increase resilience to risks caused by climate change. The company has not carried out a detailed analysis with regard to other risks, impacts and opportunities. The company did not identify any separate significant financial effects related to material risks and opportunities during the reporting period.

The double materiality assessment was reviewed and updated in 2025. Teleste's external stakeholders were not engaged in the process of updating the assessment, as stakeholders were previously engaged in the process when conducting the 2024 assessment, and there had been no significant changes in operations.

Slight changes were made to impacts, risks and opportunities in the review. With regard to the impacts, the changes were not significant. Instead, they were corrections to the impact descriptions. The number of impacts remained unchanged. Two new risks were added to the list of material risks. The risks are related to cyber security and the topic of corruption and bribery. These topics are reported in section ESRS G1 Governance and corporate culture. Changes were also made to material opportunities. Compared to the previous reporting period, the number of opportunities decreased from five to three.

The results of the 2025 double materiality assessment have been reviewed and approved in accordance with Teleste's sustainability management model.40

IMPACT, RISK AND OPPORTUNITY MANAGEMENT

DESCRIPTION OF THE PROCESSES TO IDENTIFY AND ASSESS MATERIAL IMPACTS, RISKS AND OPPORTUNITIES (IRO-1)

Teleste has an established and regularly repeated Group-wide risk management process, which is supplemented by an ESRS-compliant double materiality assessment. A double materiality assessment of sustainability has been utilized in assessing the themes and impacts that guide Teleste's sustainability efforts.

In 2024, Teleste conducted a materiality assessment in accordance with the ESRS, based on which the key impacts, risks and

opportunities related to the company's business were assessed, particularly from the perspective of sustainability. The aim was to identify and assess the impacts, risks and opportunities that may be of relevance to the implementation of the company's strategy in the short and long term, while simultaneously identifying and assessing the impacts of the company's business activities on society and the environment. The company's previous risk management process was primarily focused on identifying and assessing risks, threats and opportunities that are relevant to the implementation of the company's strategy or maintaining the company's value. The double materiality assessment adds to the established risk management process the company's impacts on society and the environment, as well as the risks and opportunities associated with them.[41]

The process of determining material impacts began with a background analysis. The purpose was to generate a long list of

potential impacts on people and the environment in Teleste's context. The background analysis took into account Teleste's business objectives, values, impacts relevant to the industry and reporting requirements. The long list of impacts included a total of 125 impacts that were grouped into 21 ESG themes (short list) to facilitate the determination of materiality.

The next step was to decide which stakeholders to include in the assessment. In the materiality assessment, the most significant stakeholders were defined as suppliers, customers, shareholders and investors, as well as the company's own personnel. As the company's Board of Directors also includes shareholders, the Board of Directors represented the perspective of investors and shareholders in the materiality assessment.

Priorities were assigned to the impacts on people and the environment on a scale of 1-5 by both stakeholder representatives and Teleste's personnel. This score represented the significance of each impact. The overall score for impact materiality also consisted of scope (on a scale of 1-5), irremediability (on a scale of 1-5) and likelihood (on a scale of 0-1, where 1=100%).

Impact materiality was assessed on the basis of the total of the four scores or high significance. For the total score, the materiality threshold was defined as 3. Impacts with a significance score of 4 or higher were also defined as material.

In connection with the assessment of material impacts, the aim was to take impacts on people and the environment into account as broadly as possible by engaging different stakeholders in the assessment.

In the background analysis behind the long list of impacts, efforts were made to take the entire industry's impacts into consideration. The value chain perspective was taken into account by engaging both suppliers and customers in the process. The stakeholder perspective was taken into account by interviewing representatives of external stakeholders. The company's own personnel also participated extensively in the materiality assessment. Representatives of external stakeholders assessed the materiality of the impacts. External experts were used in the materiality assessment.

Impact materiality was assessed on the basis of the significance, scope, irremediability and likelihood of the impacts. For negative impacts, the assessment also took into account the irremediable character of the impact: if the total score for an impact did not exceed the materiality threshold but its irremediable character was assessed as high, it was identified as a material impact. The impacts were divided into actual and potential impacts. For potential impacts, the likelihood of the impact was also determined. No particular functions or business relationships with an elevated risk of adverse impacts were separately identified or taken into account in connection with the process. All of the actual and potential impacts that exceed the materiality threshold are material.[42]

The assessment of material risks and opportunities also began with the preparation of a long list of potential sustainability-related risks and opportunities. The list was prepared on the basis of Teleste's risk analysis and supplemented by opportunities and other risks in a workshop. The list included a total of 150 risks and opportunities, covering all 10 ESRS standards and certain company-specific topics.

The scale and likelihood of the risks and opportunities were assessed by project managers. The assessment included the following perspectives: scale: Impact on the company's development, financial position, financial performance, cash flows, access to financing or capital costs in the short, medium or long term. The scale was estimated in millions of euros. Likelihood: How likely is it that the risk or opportunity will materialize. Likelihood was assessed on a scale of 0-1, where 1=100% likelihood of materialization.

The analysis of risks and opportunities was based on the same background material as the assessment of impacts. For example, with regard to climate risks, the link between impacts and risks and opportunities is clear.

A risk or opportunity was considered material if its scale exceeded EUR 1.35 million or if the total impact and likelihood score was 1 or higher (on a scale of 0-3).

The materiality assessment focused particularly on assessing sustainability-related risks. Drawing the line between sustainability-related risks and other risks was challenging in some respects. When the risks were analyzed in more detail, it became apparent that it was difficult to justify the link between climate change and changes in exchange rates, which were defined as a material risk, for example. In connection with the reporting on the year 2024, it was also observed that the link between the impacts and the risks and opportunities should be taken into consideration in more detail in connection with the double materiality assessment.

As the double materiality assessment on which the sustainability reporting is based was carried out as a separate process, its results are not fully comparable with the company's previous materiality or risk assessments. The company considers sustainability-related risks to be of equal value to other risks. However, with regard to the reporting on 2024, the low comparability of the results of different analyses did not make it possible to apply the same process to taking all of the company's risks into account in financial and sustainability reporting. This was taken into consideration in the development of the risk and opportunity assessment process in 2025. In accordance with the current practice, sustainability-related risks and opportunities are assessed and addressed as part of the Group-level process for managing risks and opportunities.[43]

The material impacts, risks and opportunities were analyzed in a workshop led by an external expert. Members of Teleste's materiality assessment project team participated in the workshop. The project team also included members of Teleste's Leadership Team. The materiality thresholds were defined in the workshop. The final report on the materiality assessment and the material aspects of sustainability were also approved by the company's Board of Directors.[44]

The risks and opportunities identified as material in the double materiality assessment are included in the Group's register of risks and opportunities. The sustainability-related risks and opportunities identified as part of the Group-level risk and impact management process serve as inputs to the double materiality assessment process.[45]

The company considers its sustainability-related risks to be equal in value to other risks, and takes sustainability-related risks and opportunities into account as part of the process for assessing risks and opportunities.⁴⁶

The materiality assessment is based on a background analysis. The background analysis took into account Teleste's business objectives, values, impacts relevant to the industry and reporting requirements. The background material for the assessment of risks and opportunities also included a climate risk analysis, among other things.⁴⁷

Based on the significant (material) impacts, Teleste identified the reporting requirements that its sustainability report should cover. The topic-specific reporting standards relevant to Teleste are as follows:

  1. ESRS E1, climate change
  2. ESRS E5, resource use and circular economy
  3. ESRS S1, own workforce
  4. ESRS G1, governance and corporate culture

Teleste's sustainability strategy and targets are also described in accordance with ESRS 2.

The aspects to be reported on were defined as part of the double materiality assessment project. The ESRS requirements were taken into account in determining the material impacts, risks and opportunities. The standards to be reported on were determined on the basis of the aspects identified in the double materiality assessment.⁴⁸

The background analysis for the materiality assessment process aimed to comprehensively take into account the potential impacts, risks and opportunities in Teleste's context. Aspects related to pollution, water and marine resources, and biodiversity and ecosystems were also represented in the materiality assessment's short list covering 21 ESG themes, based on which the representatives of stakeholders determined Teleste's most material themes. Impacts, risks and opportunities related to environmental pollution, water use and wastewater in the context of Teleste's own operations are managed as part of the Group's environmental management system.

Teleste has assessed, at a high level, the actual and potential impacts on biodiversity and ecosystems in the vicinity of its sites by applying the Key Biodiversity Areas criteria. No separate assessment has been conducted for the value chain. According to the Key Biodiversity Areas criteria, Teleste's sites are not located in or near biodiversity-sensitive areas. Teleste's production facilities or offices are not subject to environmental permits. With regard to the production facilities or other sites, the company has not identified any need to implement mitigating measures related to biodiversity.

Aside from the materiality assessment, no separate consultations of stakeholders or affected communities have been organized.⁴⁹

Description of the processes to identify and assess material climate-related impacts, risks and opportunities (E1. IRO-1)

Teleste has identified and assessed climate change-related impacts, risks and opportunities in its materiality assessment. Climate change and its effects were identified as a material impact. The materiality assessment is discussed in more detail at the beginning of this section.⁵⁰

Teleste had previously identified and assessed climate change-related risks and opportunities in a climate risk analysis conducted in 2023. In connection with the climate risk analysis, Teleste sought to systematically identify potential risks and business opportunities related to climate change. Of these, the potential risks and business opportunities that are the most significant to the company's operations were identified. These identified risks and opportunities served as input for the 2024 double materiality assessment, in which risks were also considered more broadly from the perspective of stakeholder relations. The assessment covered the identification of physical and transition risks related to climate change, as well as an assessment of the magnitude and likelihood of each risk.

The company utilized the TCFD recommendations and IPCC scenarios in the assessment of the climate risk exposure of its assets and operations. The assessment covered the most significant sites and operations.⁵¹ Two scenarios were used in the risk assessment: the first scenario assumes that global temperatures will rise by 1.5–2°C, and the second scenario assumes that global temperatures will rise by more than 4°C by 2100 (based on RCP 2.6 and IPCC 2022 SSP1-2.6 and RCP 8.5 and IPCC 2022 SSP5-8.5).

In the scenario that is based on a temperature rise of less than 2°C, the assumptions are that the demand for GHG emission-reducing products and services will grow and regulation will increase, requiring the development of the transparency of the chain of production, for example. Also in this scenario, carbon tariffs, the EU's Carbon Border Adjustment Mechanism (CBAM) and other regulations related to carbon pricing and emissions trading are projected to have an impact on the business environment. In the under 2°C scenario, the worst physical risks would be avoided and exposure to the adverse impacts of these risks is lower in Northern Europe than elsewhere. Nevertheless, the scenario would entail an increase in physical risks, such as storms, tornadoes, floods and forest fires. However, the number of geographical regions where living and working conditions become impossible or productivity falls significantly due to the temperature is low in the under 2°C scenario.

In the over 4°C scenario, it is assumed that the business environment will become more unpredictable or unstable. With regard to technologies, adaptation is expected to require investments and the development of products and services that promote adaptation. Market risks and availability problems for basic commodities and raw materials are possible. In addition, in this scenario, the loss of peace and free movement is possible, as are waves of climate refugees. Physical risks would increase and potentially cause not only direct harm to assets and people, but also indirect losses due to factors such as disruptions in logistics and procurement, interruptions in business operations, repair costs and costs arising from adaptation. On some continents, the changes could lead to loss of life, health or productivity.⁵²

The 1.5–2°C scenario is particularly useful in the identification and assessment of transition risks, while the over 4°C scenario provides a better foundation with regard to physical risks.⁵³

The assessment took into account the potential physical and transition impacts of climate change in Teleste's markets, as well as impacts on suppliers and customers in the value chain close to Teleste. The location of Teleste's production facilities was taken into consideration in the scenario analysis, particularly with regard to the likely impacts of physical climate risks. The analysis also took into account the geographical location of significant customers and suppliers in order to assess the risk posed by a potential sea level rise, for example.54

Risks were identified in the short, medium and long term. The climate risk assessment covers an assessment of the threats posed by climate change to Teleste's assets and business operations in the short, medium and long term.55 The time horizon was defined as follows: in the short-term time horizon, the risk was estimated to be realized by 2026, in the medium-term time horizon by 2030, and in the long-term time horizon by 2050.56 The same principles were also applied in the identification of transition risks and the assessment of exposure.57

The assessment of physical risks and hazards covers extreme weather phenomena, sea level rise and long-term impacts of climate change. In the short term, the hazards posed by the sudden impacts of weather phenomena, such as floods and storms, were taken into account. In the long term, the assessment focused on permanent changes and hazards, such as sea level rise and a permanent rise in temperatures. With regard to transition risks, the impacts

of tightening regulation on the company's competitiveness have been taken into account, for example. Scenario-based analysis provides a foundation for risk prioritization and the planning of adaptation strategies.58 The use of scenarios ensures that the assessment covers the risks in potential serious developments, which supports strategic decision-making and the planning of adaptation measures.59 Experts from different parts of the organization were engaged in the risk assessment. Consequently, Teleste is of the view that the scenarios applied cover the company's likely risks and uncertainties.60 Climate risks are part of the risk assessment process managed by the CFO. The climate scenarios used are not in conflict with the critical climate-related assumptions used in the financial statements.61

The analysis of climate risks and opportunities assessed the impacts on business operations caused by hazards, transition events or physical risks related to climate change. Impacts on strategy and business operations were examined in more detail in connection with the resilience analysis. Climate risks and their management are discussed in more detail in section E1 Climate change, in the table "Resilience analysis".62

Teleste's business supports the green transition because, among other things, it promotes the use of public transport and provides energy-efficient network solutions. The company has not identified assets or business activities that are incompatible with or need significant efforts to be compatible with a transition to a climate-neutral economy. Some of Teleste's business activities promote the environmental objectives related to climate change mitigation and adaptation as defined in the EU Taxonomy. These business activities are described in more detail in the following section: Disclosures pursuant to Article 8 of Regulation (EU) 2020/852 (Taxonomy Regulation).63

2. Environmental Information

EU TAXONOMY

DISCLOSURES PURSUANT TO ARTICLE 8 OF REGULATION (EU) 2020/852 (TAXONOMY REGULATION)

The taxonomy is a classification system for the financial market based on Regulation (EU) 2020/852, valid from the beginning of 2022, listing economic activities that are sustainable with respect to the climate and the environment. The goal of the taxonomy is to reorient capital flows towards sustainable investments so that the EU can achieve the ambitious emission reduction targets it has set for itself. The taxonomy defines six key environmental objectives against which the company's various business activities are assessed. The environmental objectives are: (1) climate change mitigation, (2) climate change adaptation, (3) the sustainable use and protection of water and marine resources, (4) the transition to a circular economy, (5) pollution prevention and control, and (6) the protection and restoration of biodiversity and ecosystems.

The technical screening criteria determine whether a given economic activity contributes substantially to the achievement of the environmental objectives in question, in which case the activity can be classified as sustainable. In addition to considering the fulfillment of the technical screening criteria, it is necessary to ensure that the activity in question does no significant harm to any of the other five environmental objectives and that the activity is aligned with the UN Guiding Principles on Business and Human Rights and the OECD guidelines. The reporting obligation includes reporting the percentage share of taxonomy-eligible and taxonomy-aligned turnover, capital expenditure (CapEx) or operating expenditure (OpEx).

Taxonomy-eligible activities

Teleste's business is partly within the scope of the EU Taxonomy Regulation, i.e. taxonomy-eligible. Screening criteria concerning climate change mitigation or the transition to a circular economy can be applied to Teleste's activities. The taxonomy items 6.14 "Infrastructure for rail transport" and 6.15 "Infrastructure enabling low-carbon road transport and public transport", which are related to climate change mitigation and long-distance passenger rail transport, can be applied to the business activities of the Public Safety and Mobility unit. Among the criteria that concern contributing to the transition to a circular economy, item 4.1 Provision of IT/OT data-driven solutions, under the information and communication section can be applied to part of the business activities of Teleste's Broadband Networks unit.

The company has no activities related to the production of nuclear power or fossil energy, chemicals production, controversial weapons or tobacco products.^[64]^

Taxonomy reporting

For the financial year 2025, Teleste reports taxonomy-eligible and taxonomy-aligned business activities in relation to all six environmental objectives. Proportions of turnover, capital expenditure and operating expenditure are reported for the business activities.

Screening process for taxonomy-eligible and taxonomy-aligned activities

Teleste has assessed its taxonomy eligibility and taxonomy alignment for the financial year 2025. The process included the identification of taxonomy-eligible activities, the assessment of the technical screening criteria and Do No Significant Harm criteria for each environmental objective for all relevant activities, and the assessment of the minimum social safeguards at the company level.

The taxonomy-eligible and taxonomy-aligned share of turnover was assessed for each of the company's businesses.

Teleste has already previously reported taxonomy-aligned business activities that contribute to climate change mitigation. Teleste's taxonomy-aligned activities within the scope of categories 6.14 and 6.15 include, among other things, the company's public transport information solutions for rail transport and video security solutions for public transport applications. For these functions, only external sales are included in the reported turnover. In addition, part of the business activities of Teleste's Broadband Networks segment is taxonomy-eligible according to category 4.1 of the criteria concerning contribution to the transition to a circular economy. These activities include maintenance and repair activities and remote network monitoring solutions, among other activities.

Reporting principles

Turnover

Teleste applies the same IFRS accounting principles as in the consolidated financial statements when calculating the turnover KPI. The total turnover used in calculating the KPI corresponds to the net sales figure presented in the consolidated financial statements. The accounting principles concerning net sales are presented in note 2.2 to the consolidated financial statements.

The taxonomy-eligible and taxonomy-aligned share of turnover was assessed for each of the company's businesses. Only external sales are included in the reported turnover.

Capital expenditure and operating expenditure

The share of capital expenditure and the share of operating expenditure related to economic activities that are considered to be environmentally sustainable are reported at the company level on a cost center basis, avoiding double counting under and between the KPIs. Examples of such activities include research and development projects.

DESCRIPTION OF THE PROCESS TO IDENTIFY AND ASSESS MATERIAL CLIMATE-RELATED IMPACTS, RISKS AND OPPORTUNITIES

Teleste has identified and assessed climate change-related impacts, risks and opportunities in the double materiality assessment. Climate change and its effects were identified as a material impact. A description of the processes to identify and assess material impacts, risks and opportunities is provided in the section "Impact, risk and opportunity management" in the paragraph "Description of the process to identify and assess material impacts, risks and opportunities (IRO-1)".67

MATERIAL IMPACTS, RISKS AND OPPORTUNITIES AND THEIR INTERACTION WITH STRATEGY AND BUSINESS MODEL (E1 SBM-3)

Teleste conducted a resilience analysis in 2024, in which the resilience of the company's business was assessed in relation to the climate risks identified in 2023. The resilience analysis takes into account Teleste's own operations and the impacts of climate change on suppliers and customers. The analysis does not include impacts further out in the upstream or downstream value chain. Consequently, risks related to the procurement of raw materials required in the production of components were not examined, for example. All of the physical risks and transition risks identified as material were reviewed in the resilience analysis. To improve understandability, the risks were grouped, and the most significant of these groups are presented in this report. The results are described in table 8 Resilience analysis.68

A critical assumption made in the assessment is that the transition to a lower-carbon and more climate-resilient economy will lead to increased regulation and a more unstable business environment. Another assumption is that the need for, and significance of, energy-efficient solutions and stable network connections will grow. The uncertainties in the resilience analysis include changes in regulation and markets, the speed of technological development, the unpredictability of the impacts of climate change, and supply chain vulnerabilities.69

With regard to many risks, the impacts on Teleste's business and the measures to prepare for the risk were quite similar in practice. The resilience analysis was carried out in cooperation with the organization's various experts to ensure a diverse and comprehensive view. Estimates of the financial effects of the risks, as determined in connection with the climate risk and materiality assessment, were utilized in the analysis. The process began with the identification of the potential impacts of each risk on Teleste's business in different time horizons (based on RCP 2.6 and IPCC 2022 SSP1-2.6 and RCP 8.5 and IPCC 2022 SSP5-8.5).70 In the resilience analysis, the same time horizons were applied as in the climate risk assessment.71

The next step was to describe the company's preparatory measures for managing the impacts of the risk and the effect of the preparations in the event of the risk materializing were assessed. That was followed by an assessment of the extent to which Teleste's business model and strategy take at-risk assets and business activities into account. Based on this, Teleste's resilience

to the risks in question was assessed. The company's mitigation measures were taken into account in analyzing resilience. Risks and resilience are described in the table Resilience analysis. Teleste's strategy takes into account the prevailing megatrends, such as climate change, which supports adaptation to changes.72

TRANSITION PLAN (E1-1)

Teleste has not yet prepared a separate transition plan. The plan will be drawn up and approved in 2027 at the latest.73

POLICIES (E1-2)

Teleste's environmental policy is focused on reducing the company's environmental footprint and promoting positive environmental impacts. In its policy, the company commits to reducing the consumption of resources, the generation of waste and GHG emissions. The key focus areas include product design, energy consumption and the reduction of GHG emissions, the sourcing of materials, waste management and increasing employee awareness.

The company has identified that its largest climate impacts arise in the value chain and the use of the products manufactured by the company. In the double materiality assessment, the identified impacts related to climate and energy included the GHG emissions arising from the company's own operations and the entire value chain. In addition, energy consumption related to the company's own operations and logistics was identified as an impact that is related to the generation of emissions. In its environmental policy, Teleste is committed to the

continuous improvement of its operations and processes in order to reduce energy consumption and emissions. The company uses renewable energy at its factories to the extent that it is possible. These principles support the reduction of negative impacts related to energy consumption and the adoption of renewable energy.

In order to manage its emissions, Teleste calculates emissions annually in accordance with the GHG Protocol. Remote work and remote maintenance are favored in order to reduce work-related travel and emissions from maintenance-related traffic. Good production planning and the optimization and consolidation of deliveries to the extent that it is possible aims to reduce emissions arising from transport. Land and sea transport are favored over air transport, and solutions based on renewable fuels are used where possible. Together, all of these policies support the reduction of emissions and, consequently, the mitigation of climate change.

Reducing the carbon footprint of products by means of energy-efficient solutions was identified as an impact in the materiality analysis. Approximately 90% of Teleste's carbon footprint is caused by emissions generated during the use of products. Use-phase emissions are determined on the basis of the products' energy consumption, average service life and location-based emission factors for electricity. Product energy consumption therefore has a significant impact on the carbon footprint.

Product design aims to reduce the products' energy consumption and improve their energy efficiency. Policies related to product design are aimed at not only reducing neg-

ative emission impacts but also increasing positive impacts by introducing energy-efficient devices to the market. Energy-efficient solutions and products, as well as new innovative technologies, enable more sustainable and low-carbon infrastructure and the green transition, which supports climate change adaptation. They also mitigate climate change by reducing the carbon footprint of both customers and the company itself.

Policies concerning product design are described in more detail in the report section Resource use and circular economy (ESRS E5). One of the objectives of product design is to develop the reliability of products, for example. Reliable data communications connections reduce the need for travel, while up-to-date passenger information increases the attractiveness of public transport, for instance.

These mitigate emissions, but they simultaneously support climate change adaptation. Product development also aims at designing products for maintenance, and the company opts for remote maintenance when possible. In the materiality assessment, the reputational benefit and competitive advantage of leadership with regard to climate change was identified as an opportunity, and product development innovations support this.74

Sustainability risks have been integrated into the company's broader risk management process, which is guided by Teleste's risk management policy. The same policies are also applied to the climate risks identified as material. The process is described in more detail in the section "Description of the processes to identify and assess material impacts, risks and opportunities (IRO-1)". Policies related to component risk are described in the section "Policies (E5-1)".

The policies apply to all of the company's employees, subcontractors and stakeholders at all of Teleste's operating locations globally. The policy is publicly available on the company's website. The policy applies to product design, energy consumption, materials procurement, waste management and the company's value chain, including transport and distribution. No separate exceptions are mentioned. The aim of the environmental policy is to address the most significant environmental impacts, particularly those that arise in the company's value chain and the use of products. Teleste's management is responsible for the realization of the principles laid down in the environmental policy. The Leadership Team monitors compliance with the policy, sets environmental targets and regularly monitors progress. Teleste complies with the environmental principles of the UN Global Compact initiative and ensures that its operations comply with environmental legislation and regulations.75

The policy also takes into account the views of key stakeholders through the materiality assessment. The company ensures that its environmental targets and practices are aligned with stakeholder expectations and global sustainability trends. In addition, Teleste's Supplier Code of Conduct aims to engage the company's suppliers' commitment to monitoring their GHG emissions and setting emission reduction targets that support the Paris Agreement. This supports the promotion and implementation of sustainable practices throughout the value chain.76

MEASURES (E1-3)

Teleste's measures for managing the climate-related risks identified in the double materiality assessment are described at the beginning of section E1, in Table 8 "Resilience analysis".

In the NET service business in Finland, Teleste's focus moving forward will be on network operation and design. As a result, the company has phased out the vehicles related to the business in question. This has a positive impact on the company's scope 1 emissions. Key measures to reduce scope 2 emissions include reducing energy consumption and switching to renewable energy sources where possible. During the reporting period, Teleste purchased zero-emission electricity for its offices in Littoinen and Tampere in Finland, as well as in Hanover in Germany and Birmingham in the United Kingdom. Roof renovation was carried out at the manufacturing plant in Littoinen in 2023, which makes it possible to install solar panels on the roof in the future. In addition, various energy-saving and energy efficiency measures were successfully continued in Littoinen. The energy-saving measures helped to reduce district heating consumption by approximately 6% when compared to 2024, although it should be noted that the winter in Finland was mild. Electricity consumption decreased by approximately 2%. The outcome was influenced by the high utilization rate of charging points for electric cars. In addition, the factory operated on three shifts for part of the year under review, which was not the case in 2024. The measures taken reduced the emissions of the Littoinen site by 17 tCO2eq, as the electricity consumed was 100% CO2-free.

To reduce scope 3 emissions arising from transportation, Teleste favors sea and land transport over air freight. In addition, the company strives to reduce transportation-related emissions by consolidating shipments and using renewable fuels in transport operations where possible. With regard to road freight, the use of biofuel was expanded to include not only domestic transport but also part of international transport. In the latter part of the reporting period, SMF (sustainable marine fuel) was also introduced in deliveries to the United States. In addition, Teleste has increased the use of partial SAF (sustainable aviation fuel). Combined, these measures reduced transport emissions by 25 tCO2eq (the effect of SMF has not been taken into account).

The measures are planned to be implemented in the medium term so that the targets set for 2026 and 2030 can be achieved. The outcomes for 2025 in relation to the targets are shown in the table Emission reduction targets.77 During the reporting period, the company increased the accuracy of its emissions calculations and improved their coverage. Comprehensive emissions data was also calculated for the base year 2022 and the year 2024. In addition, as a measure related to the mitigation of emissions, Teleste has worked on science-based emission reduction targets.

Product design aims to reduce the energy consumption of products and improve their energy efficiency. The company favors recycled materials in its procurement activities, which not only promotes the circular economy but also reduces the climate impact of procurement. The use of recycled aluminum is discussed in more detail in section ESRS E5,

paragraph "Metrics and targets (E5-3)" and the company's use of materials in a broader sense is discussed in paragraph "Resource inflows, including resource use (E5-4)". All of the measures related to the climate and the reduction of emissions support the company's strategic goal of being an ESG leader in its industry. The company actively monitors the global situation, legislative developments and megatrends in sustainability in order to also manage the other key opportunities identified in the materiality assessment.78

As part of the ISO 14001-compliant environmental management system, the company carries out annual assessments of environmental aspects and environmental risks and continuously develops its operations based on them, among other things. Energy-saving at properties and improving energy efficiency, the procurement of renewable energy, using renewable fuels in logistics and other measures aimed at reducing emissions reduce the climate impacts caused by the company's operations.79 The company has included the management of climate action as part of its business, and the expenses have therefore not been disaggregated from other expenses. Consequently, the magnitude of separate financial resources allocated to individual measures is not significant. Teleste considers that the current resources are sufficient to implement the planned measures in the short term. The action plan for the reporting period did not require separate operating or capital expenditure classified as significant. The company has not planned to increase the operating or capital expenditure related to the measures for the next reporting period. The company has also not created a medium

or long-term capital investment plan related to climate and energy measures.80

Teleste's key decarbonization levers include the use of renewable energy, reducing the emissions of the logistics chain, the circular economy and sustainable use of materials, taking energy efficiency into account in product design, employee training and promoting the environmental awareness of employees.81 In addition, the company is working on a calculation of the impacts of its measures on emissions as part of setting science-based climate targets. Engaging supplier and customer commitment to setting science-based climate targets has been identified as one significant lever in connection with this. The calculation will serve as the basis for the company's transition plan.82

The resources and investments allocated to the measures must be proportionate to the size of the business and the financial situation. The allocation of resources is also influenced by the customers' willingness to pay, which determines how much investment can be allocated to sustainable and emission-reducing measures. Without sufficient financial resources and market support, it is challenging to achieve long-term environmental targets, but the company is committed to ensuring that climate change mitigation is part of its sustainable business model.83 As not all of Teleste's business activities are taxonomy-eligible, the indicators presented in the taxonomy tables at the beginning of section 2 "Environmental information" only apply to taxonomy-eligible business activities. The same principles have been applied in compiling the figures, but they are not consistent due to the different scope of assessment.84

Progress towards targets

Reducing scope 1 emissions from the 2022 level

Direct scope 1 emissions were close to the 2024 level, and the company has maintained its the short-term target level. Fuel consumption in the service business was lower than previously, which means that most of these emissions consist of refrigerant refills.

Reduction of scope 2 emissions (market-based) from the 2022 level

Indirect emissions arising from purchased energy decreased from the 2022 level, and the short-term target was also achieved with regard to scope 2 emissions. The outcome is partly influenced by the boundary applied to the target. The target only covers sites with 10 or more workers.

Reducing scope 3 transport emissions, relative to metric tons transported, from the 2022 level

Transport emissions relative to metric tons transported increased slightly from the previous level. In sea shipping, the continued situation in the Red Sea extended transport times and increased the total mileage and fuel consumption of sea shipping. In addition, for reasons related to risk management and with regard to deliveries to the United States, Teleste had to rely on air freight more than planned in order to adhere to customer schedules.86

The climate-related sustainability targets set by Teleste are to reduce scope 1 emissions by 40% by 2026 and by 100% by 2030 from a 2022 base year. The scope 2 (market-based) emission reduction target is 20% by 2026 and 50% by 2030. These targets are absolute reduction targets and

are presented in Table 9 Emission reduction targets. In addition, for scope 3 transport-related emissions, the target is to reduce emissions in relation to metric tons transported by 10% by 2026 and by 20% by 2030. This target is relative and expressed in terms of transport-related emissions relative to the mass transported. The unit is tCO2eq per metric ton transported. With regard to the opportunities identified as material in the double materiality assessment, the company has a strategic target of being an ESG leader in its industry, but no separate metrics have been defined for this target. The company also has not set any metrics or official targets concerning the energy consumption or efficiency of products. The company has not set official sustainability targets for managing the climate-related risks presented in Table 8 "Resilience analysis".

Teleste's science-based emission reduction targets were approved at a meeting of the Leadership Team in January 2026. The targets have yet to be validated by the SBTi. For this reason, the targets have not yet been published, and they do not influence the reporting or target setting for 2025. The company did not deem it appropriate to make changes to its existing targets before the targets are officially approved by the SBTi.

The assumption behind the company's emission reduction targets is that improving energy efficiency and switching to renewable energy and fuels are key means of reducing scope 1 and 2 emissions. For this reason, the monitoring of emissions from Teleste's own operations (scope 1 and 2) is considered to be an illustrative metric for the management of emissions from the company's own operations. With regard to scope 3 emissions, the assumption behind the relative emission reduction target for transport operations is that the optimization of the logistics chain, the deployment of low-emission transport solutions and the use of alternative fuels are effective ways of reducing transport-related emissions. Consequently, transport-related emissions in relation to metric tons transported is considered to be an illustrative metric for the climate impacts of logistics.[87]

The environmental targets are set on the basis of the key environmental aspects and the results of the materiality assessment. The materiality assessment also takes into account the views of stakeholders, such as customers, but stakeholders have not been involved in setting the targets. After identifying the environmental impact, the available data for describing the impact was determined. This was followed by defining a suitable metric and a target level for it. Development is monitored continuously and the results are reviewed regularly by the Leadership Team.[88] The targets are stated in the environmental policy and the operating principles defined in the policy support the achievement of the targets.[89] In 2023, Teleste's emissions calculation was expanded to cover the most significant scope 3 emissions for 2022. At the time, this served as the basis for updating the emission reduction targets. When the targets were revised, the base year was also updated. The GHG Protocol and the IPCC's publications based on climate science were also utilized in defining the targets. The Paris Agreement and the related goals were also among the background factors in setting the targets. The company's

climate targets support the EU's 2050 climate neutrality target, the Fit for 55 package and national emission reduction targets. In terms of their ambition, the current scope 1 and 2 targets are aligned with the 1.5°C goal of the Paris Agreement but, in terms of coverage, the current targets do not meet the SBTi criteria. The targets promote the transition to a low-carbon economy, particularly through the target of reducing logistics emissions. Teleste is committed to setting science-based emission reduction targets by October 2026.[90]

The scope 1 and 2 emission reduction targets set by the company cover its operations in Finland and those locations abroad where the number of internal employees is 10 or higher. The scope 1 reduction target takes into account the fuel consumption of company-owned vehicles used in the service business, as well as refrigerant leaks. This means that the target does not include full benefit cars provided to personnel, for example. The emission reduction target concerning scope 3 transport operations covers transports departing from and arriving in Finland, as well as also transports arriving at and departing from the warehouse in Belgium. The transported products are under Teleste's ownership and consist of PBI products purchased from subcontractors and contract manufacturers.[91]

Teleste improved the coverage of emissions calculations during 2025, and emissions in accordance with the ESRS for the base year 2022 and for 2024 and 2025 are presented in the table "GHG emissions by emission class and category" in section E1-6. The calculation of emissions in accordance with the ESRS includes all scope 1 and scope

2 emissions, as well as the scope 3 emission classes identified as material, which account for over 95% of total emissions. The calculation is carried out annually in accordance with the GHG Protocol.

The calculation boundary and assumptions in accordance with Teleste's reduction targets are not fully consistent with the requirements of the ESRS. Consequently, there are two different scope 1 and 2 figures in the report. The transport emission data used in calculating the outcome for the emission reduction target for scope 3 transport also deviates slightly from the figures presented in Table 12 "GHG emissions by emission class and category". However, the target related to transport covers more than 95% of total transport emissions. The scope 2 emission reduction target covers more than 90% of scope 2 emissions calculated in accordance with the ESRS, and the coverage for scope 1 is nearly 70%. Consistency has been taken into account in the setting of science-based emission reduction targets, and the boundary will be adjusted to align with the ESRS and the SBTi criteria starting from 2026.[92]

Teleste assesses the suitability of the base year in connection with the calculation and, in accordance with the GHG Protocol, updates the base year if the operations change significantly. The 2022 base year for the target covers the activities included in the target.[93] The metrics have not been verified by an external party other than the company's sustainability reporting assurance provider.[94] No changes have been made to the basis of preparation of the metrics illustrating the targets during the specified time horizon. However, for scope 1, the figures disclosed

in the previous reporting period have been supplemented with regard to refrigerants.95 Climate scenarios were also utilized as background material in setting science-based emission reduction targets. That was not the case for the current targets. However, different potential developments have been examined in connection with the climate risk assessment and resilience analysis.96

For scope 2 emissions, for sites for which consumption data on heating is not available, the emissions have been estimated on the basis of the number of personnel. As is typical, estimates and generalisations have also been made in the calculation of scope 3 emissions in particular. Supplier-specific emissions data and factors have been used in the calculation of emissions whenever they are available, thus aiming for the most accurate possible calculation result. The aim is to continuously improve the accuracy of the data. Category 4 "Upstream transportation" includes supplier-specific emission data to the extent such data is available. Otherwise, the calculation is based on metric ton kilometers. The utilization rate of transport equipment is not taken into account in category 9.97

ENERGY CONSUMPTION AND MIX (E1-5)

The energy consumption figures include the fuel consumption of vehicles under the company's control, including vehicles used by employees who have a full benefit car, as well as energy consumption related to electricity and heating from all of Teleste's sites. The reported energy consumption figures are therefore consistent with the scope 1 and 2 emission figures presented in the paragraph "Gross Scopes 1, 2, 3 and Total GHG emis

sions (E1-6)". These calculations differ from Teleste's emission reduction targets presented in paragraph "Metrics and targets (E1-4)" in the sense that they also include very small sites. For the smallest sites, consumption data has been estimated on the basis of the number of personnel. For units where the source of energy is unknown, it is assumed that 60% of the energy is from fossil sources and 40% is from renewable sources. However, this assumption only applies to a very small proportion of energy consumption, as more than 95% of the energy purchased comes from known sources. If the form of heating is not known, the assumption is that it is district heating. The roof of the Forssa site is equipped with solar panels. The energy generated by the solar panels is used for Teleste's functions. The figures presented in the previous reporting period have been restated to include the fuel consumption of cars, which was missing from the previous year's calculations. This also affects the 2024 energy intensity figure, which is presented in Table 11 "Energy intensity per net sales".

Teleste's NET business segment focuses on the manufacture of electronic components, which is classified by the European Union as a high climate impact sector. Energy intensity has been calculated by dividing the total energy consumption of the sites representing the NET business (5,312 MWh) by the net sales of the business segment in question, which is based on the Broadband Networks segment's net sales as presented in section "Segment reporting" in the notes to the consolidated financial statements 2025. The net sales figure is consistent with IFRS reporting. Properties and the energy

GROSS SCOPES 1, 2, 3 AND TOTAL GHG EMISSIONS (E1-6)

Teleste uses the GHG Protocol as the basis for calculating emissions. Teleste has defined the organizational boundaries using an approach that is based on operational control. In the calculation of emissions, Teleste has used the most accurate data available, and emission factors that are as descriptive as possible. Scope 1 emissions are based on fuel consumption data and, for refrigerants, refrigerant refills as invoiced in connection with maintenance. The calculation of refrigerant emissions is based on the global warming potential (GWP) values published by the IPCC, which are based on the IPCC's AR5 report. The fuel classifications of Statistics Finland and DEFRA (UK Department for Environment, Food and Rural Affairs) have been used in the calculation of fuel emissions data.

Scope 2 emissions have been calculated primarily on the basis of measured consumption data, but there are also units for which accurate consumption data is not available. For those units, estimates based on the size and number of personnel of the units have been used. These scope 2 emissions figures also include smaller units that are not within the boundary used for the company's emissions target. Their consumption has also been estimated based on the best available data, as mentioned above. Supplier-specific emission factors have been used in the calculation of market-based scope 2 emissions to the extent that they have been available. Emissions have been calculated as carbon

dioxide equivalents so that other significant greenhouse gases are taken into account in addition to carbon dioxide. Where necessary, location-based emission factors have been used. The sources used in the calculation of location-based emissions are the reports and databases of the EEA (European Energy Agency), IRENA (International Renewable Energy Agency) and Our World in Data. Part of the location-based emission factors are CO2 emission factors, for which the other GHG emissions (CH4 and N2O) have been calculated separately using DEFRA factors. Part of the factors used are CO2-equivalent factors, which means that they also take into account the climate impacts of other GHGs.

Teleste's scope 3 emissions cover all emissions categories that are material to the company. The calculation includes categories 1, 2, 4, 5, 6, 7, 9, 11 and 12. Emission categories 8, 10, 13, 14 and 15 have been excluded from the calculations on the following grounds:

  • Category 8 "Upstream leased assets" is included in scope 1 and 2 calculations
  • Category 10 "Processing of sold products" - Teleste only delivers finished products.
  • Category 13 "Downstream leased assets" - no such assets have been identified
  • Category 14 "Franchises" - no franchising activities
  • Category 15 "Investments" - no investments

As is typical, estimates have also been used, particularly in calculating scope 3 emissions.

Category 1 emissions have been calculated mainly on a material and mass basis, based on primary data from the ERP system. Estimates have been utilized with regard to material breakdowns. The emission factors applied by the company include, among others, DEFRA's material-specific factors and life-cycle emission data published in several industry studies and by international institutions. Emissions from services have been calculated using a spend-based method, with EXIOBASE factors primarily utilized in the calculation. The same procedure has also been applied with regard to category 2 "Capital goods", where the calculation is carried out either on a material- and mass-based method or a spend-based method, depending on the capital goods purchased.

Category 3 includes indirect emissions related to the company's fuel and energy consumption reported in scopes 1 and 2, i.e. well-to-tank (WTT) emissions from production and processing, as well as electricity transmission and distribution losses. Fingrid's data on electricity network losses and DEFRA's emission factors, among other sources, have been utilized in the calculations.

Category 4 "Upstream transportation" includes supplier-specific emission data to the extent such data is available. Otherwise, the calculation is based on metric ton kilometers. The calculation is carried out according to the well-to-wheel (WTW) principle using DEFRA factors.

Emissions from the treatment of waste generated by Teleste's own operations are partially obtained as complete emissions reports from the partner responsible for waste management. The emissions are partly

calculated on the basis of the waste data obtained and the waste treatment method, using factors from DEFRA and the United States Environmental Protection Agency (EPA). Measurement-based waste data is available for the Littoinen, Forssa and Tampere sites in Finland, representing a significant majority of the waste generated. The waste volumes for other sites are very low and have been estimated on the basis of the number of personnel. The waste data used in the calculation of emissions is therefore consistent with the waste figures reported in section E5-6. Wastewater emissions have been calculated on the assumption that the amount of wastewater generated is equal to the amount of water consumed. Water consumption data is only available for the largest sites in Finland. The wastewater amounts for other sites have been estimated on the basis of the number of personnel.

Data concerning air travel in category 6 "Business travel" has been collected from Teleste's travel booking system, and DEFRA factors have been used in the calculation. Emissions generated by business travel by employees other than those working in Finland have been extrapolated on the basis of the number of senior salaried employees. The company takes the RF (radiative forcing) impact into account in the calculations so that the climate impacts that occur in the upper atmosphere are also taken into account. In addition, Teleste utilizes data on reimbursed kilometres in the calculations, again applying DEFRA factors and WTW principles.

For 2022 and 2024, the emissions from employee commuting in category 7 are based on an estimate that covers Teleste's personnel

in Finland. The emissions have been extrapolated on the basis of the number of personnel to also cover Teleste's units outside Finland. The emission data for 2025 is based on a commuting survey conducted among the personnel during the reporting year. DEFRA factors are used as emission factors in the calculation, and the company calculates emissions in accordance with the WTW principle.

In category 9, the calculation is carried out using the WTW principle in accordance with the metric ton-kilometer method, utilizing DEFRA factors. The utilization rate of transport equipment is not taken into account in the calculation. Average distances have been applied to make the calculation clearer.

Emissions from the use of sold products in category 11 constitute the company's most significant source of emissions. Emissions have been calculated by product category based on the number of products sold during the reporting year, their average annual energy consumption and their estimated service life. The products of Teleste's NET business are assumed to be in continuous use, while the products of the PSM business are assumed to be in use most of the day, almost every day of the year. In the calculations, the lifetime of products is assumed to be 10 years as a rule, but a lifetime as long as 20 years has been applied in several product categories. The national emission factors for electricity in the most significant target countries have been used as emission factors.

In calculating the emissions for category 12 "End-of-life treatment of sold products", Teleste has utilized technical product data to estimate the amounts of materials used. As Teleste's products are designed to be easy to

dismantle, it is assumed that the materials are primarily directed to recycling after use. Emission factors from DEFRA and the EPA have been primarily used in the calculation.[101]

The electricity purchased by Teleste for its sites located in Tampere in Finland, Hanover in Germany and Birmingham in the United Kingdom has been certified as 100% renewable with guarantees of origin. The electricity used at the Littoinen site is certified 100% CO2-free electricity. Energy with guarantees of origin accounts for 50% [102] of the total consumption of purchased energy. The following have been taken into account as biogenic emissions: emissions from biomass used in the production of district heating, which amounted to 13 tCO2eq in 2025, and, for Finland, the biogenic emissions arising from the diesel distribution obligation for vehicles in scope 1, which amounted to 0.49 tCO2eq in 2025. No biogenic emissions are reported for purchased electricity. According to the assumption made by the company, if the origin of renewable electricity is unknown, the electricity in question is not considered to originate from biomass. The assumption is based on the fact that biomass is typically not the dominant energy source in electricity production. It has not been possible to account for biogenic emissions generated in the value chain due to the available data and emission factors.[103]

The company only reports scope 1, scope 2 and scope 3 emissions from the consolidated accounting group (the parent and subsidiaries), as the company does not have investees, such as associates, joint ventures or other units that are not fully consolidated. In the scope 3 calculation, data is also

collected from the value chain. Of the emissions caused by upstream transport, 82% are based on primary data obtained from transport companies. Of the emissions caused by waste generated in operations, the proportion of emissions based on primary data obtained from waste management partners is 7%. For category 12 "End-of-life treatment of sold products", the proportion is 5%. In total, 1% of scope 3 emissions were based on primary data obtained from suppliers or other value chain partners in 2025.[104] There are no significant differences between the reporting periods of Teleste and its value chain participants.[105] There have been no changes in the definition of the company and its upstream and downstream value chain that would affect the comparability of GHG emissions between the current and previous reporting period. Teleste observed that the scope 1 calculation reported for 2024 was missing part of refrigerants and part of fuels, such as the fuel consumption of vehicles used under an unlimited car benefit. The calculation has been updated accordingly in this report, also with regard to 2022 and 2024.[106]

Table 13 *GHG intensity per net revenue shows Teleste's GHG intensity, both location-based and market-based. The GHG intensity has been calculated by dividing Teleste's location-based total emissions, 113,322 tCO2eq, and market-based total emissions, 113,162 tCO2eq, by the net sales shown in the consolidated financial statements for 2025. The net sales figure is consistent with IFRS reporting.[108]

POLICIES (ES-1)

The purpose of Teleste's environmental policy is to define operating principles for minimizing negative environmental impacts and increasing positive environmental impacts. The policy is approved at the Leadership Team level, and it applies to all of Teleste's employees, contractors and stakeholders at all Teleste sites, and it is publicly available.¹¹⁰ Teleste trains its employees to ensure that everyone is familiar with the policy and understands their responsibility for putting it into action.¹¹¹

Teleste is committed to supporting sustainable development and adheres to the principles of the UN Global Compact corporate responsibility initiative. The company is committed to sustainable procurement and production practices that reduce environmental impacts and promote the circular economy. Aside from GHG emissions, Teleste's most important environmental aspects are resource use and waste generation. The operating principles defined in Teleste's environmental policy cover all key areas, which are product design, energy consumption, GHG emissions, materials management and waste management.

The company improves resource efficiency and promotes the circular economy by continuously extending the life-cycle of its products by developing their reliability, durability and serviceability.¹¹² In addition, the company strives to continuously increase the use of recycled materials in its products and packaging. Teleste procures materials from ethical and responsible sources. The guidelines for sustainable sourcing and the Supplier Code of Conduct support a sustainable supply chain. The aim of the Supplier Code of Conduct is to

set standards for the industry, and it includes requirements for the supply chain in the areas of human rights, decent work, health, safety, ethics and the environment.¹¹³

Teleste actively seeks opportunities to promote the circular economy in its operations. The company uses resources efficiently and reduces the amount of waste generated. Sales and manufacturing forecasting reduces the amount of rejected material. All waste generated in operations is sorted appropriately, and the target is to increase the recycling rate of waste to 80% by 2030. The disposal of waste is avoided.¹¹⁴ The cardboard, plastic and metals used in products and packaging are recyclable. Teleste also favors recycled materials in its procurement. The target is to increase the share of recycled aluminum in products to 96% by 2030.¹¹⁵ The targets have also been defined in the policy and they are presented in more detail in section E5, paragraph "Metrics and targets (E5.3)".¹¹⁶

The policy also takes into account the views of key stakeholders through the materiality assessment. The company ensures that its environmental targets and practices are aligned with stakeholder expectations and global sustainability trends.¹¹⁷

In order to manage the component availability risk, which is identified as a material risk in the materiality assessment, the company has defined a policy that covers a careful evaluation process for new supplier selection, continuous monitoring and classification of supplier performance, and comprehensive contractual arrangements. In addition, the company conducts regular business reviews with key suppliers to ensure the quality of cooperation and reacts quickly to any deviations.

The company also actively monitors the life-cycle of components, the financial solidity of key suppliers and changes in their ownership structure, and keeps abreast of industry news and regulatory changes, which ensures proactive and sustainable risk management.¹¹⁸

MEASURES (ES-2)

The scope of application of the key measures covers the entire product life-cycle, from product design and materials procurement to disposal, with the aim of promoting sustainable resource use and the principles of a circular economy. Impacts related to product development identified in the double materiality assessment include promoting the circular economy by producing easily recyclable and repairable products, and reducing adverse environmental impacts through products with long life-cycles. To promote these impacts, Teleste conducts an environmental review of all new product families to assess the choices of materials, serviceability and upgradability, for example. This is an established practice and part of the company's product development process. Extending the life-cycle of products and choosing environmentally friendly materials can significantly reduce adverse environmental impacts and promote the circular economy. In addition, the serviceability and repairability of products reduce unnecessary consumption of resources and emissions caused by new production.

Key actions from a procurement perspective include increasing the use of recycled materials, favoring recyclable packaging, reducing the use of water and resources in the supply chain, and requiring suppliers to comply with strict environmental requirements.¹¹⁹ To reduce the environmental impacts of procurement, the company requires its suppliers to comply with environmental standards through audits, assessments and surveys. Potential deficiencies are addressed by drawing up a plan for remedy together with the supplier. These actions ensure compliance with requirements concerning the climate, the use of natural resources and the treatment of waste, provide structured solutions to address identified deficiencies, and promote sustainable improvements in the supply chain.¹²⁰

In order to manage the environmental impact of raw material consumption and the impact of the recycling rate of materials, the company allocated increased resources to sustainable procurement, as planned. The supplier sustainability survey was also repeated, as planned, during the reporting period. The survey is planned to be carried out at two-year intervals. The previous survey was carried out in 2023. The survey provides the company with more detailed information resource use among its suppliers. The company also aims to influence potential shortcomings and the progress of remedies in connection with supplier business reviews, for example. The measures taken during the reporting period do not directly contribute to the target of increasing the share of recycled aluminum in Teleste's products.

Waste generation is one of the impacts identified in the double materiality assessment. All waste generated in Teleste's operations is sorted carefully and the aim is to minimize the amount of waste in all operations. The disposal of waste is avoided. To reduce this impact, the company organizes

sorting training for the personnel whenever necessary. The most recent sorting training was held in 2023. In addition, as part of orientation training, new employees complete an online course on the subject of the environment, which covers the content of Teleste's environmental policy, so that everyone understands their responsibilities with regard to environmental protection. Teleste is a member of a producer responsibility organization for electrical and electronic equipment and packaging materials, which ensures that the recycling and appropriate treatment of these materials is carried out in accordance with applicable legal requirements.[121]

In the materiality assessment, component supply disruptions due to geopolitical threats were identified as a material risk from the perspective of resources and the circular economy. To manage component availability risk, the company conducts supplier risk assessments. In addition, an established process for new supplier evaluation and selection is applied. The product life-cycle is evaluated in regular reviews focused on the life-cycle of active

products. The availability of any critical materials used in the products is also examined in connection with the review. Teleste regularly seeks alternative components to manage country risk. The measures support the policies related to these impacts and risks.[122]

The company has included the management of resource use and circular economy as part of its business, and the expenses have therefore not been disaggregated from other expenses. Consequently, the magnitude of separate financial resources allocated to individual measures is not significant. Teleste considers that the current resources are sufficient to implement the planned measures in the short term. The action plan for the reporting period did not require separate operating or capital expenditure classified as significant. The company has not planned to increase the operating or capital expenditure related to the measures for the next reporting period. The company has also not created a medium- or long-term capital investment plan related to resource use and circular economy measures.[123]

METRICS AND TARGETS (E5-3)

Progress towards targets

Increasing the share of recycled aluminum in Teleste's products

The share of recycled aluminum in Teleste's products was close to the 2024 level. The company continues to work with suppliers to ensure greater transparency and assurance of the use of recycled aluminum.

Increasing the waste recycling rate

The waste recycling rate has increased slightly from the 2024 level, exceeding the short-term target set by the company.[124]

The company's target is to increase the recycling rate for waste generated in its own operations to 75% by 2025 and to 80% by 2030. Another target is to increase the share of recycled aluminum in Teleste's products to 94% by 2025 and to 96% by 2030. The company does not have official sustainability targets concerning the management of other impacts, risks or opportunities identified as material in the double materiality assessment.[125]

Teleste sets environmental targets on the basis of the most important environmental aspects and the results of the materiality assessment. The materiality assessment also takes into account the views of stakeholders, such as customers, but stakeholders have not been involved in setting the targets themselves. After identifying the environmental impact, the available data for describing the impact was determined. This was followed by defining a suitable metric and a target level for it. The Leadership Team monitors the results regularly.

Most of the waste generated by Teleste's operations is recyclable. Based on this, it is assumed that the waste recycling rate is a descriptive metric for the environmental impacts of waste. With regard to recycled aluminum, the assumption behind the metric is that aluminum has a significant environmental impact, and that this impact can be reduced by favoring the use of recycled aluminum. The share of recycled aluminum is therefore assumed to effectively reflect the environmental impact of the materials used in products.[126]

The targets are stated in the environmental policy and the operating principles defined in the policy support the achievement of the targets.[127] Both of the sustainability targets set are absolute.[128] The targets reduce the use of virgin raw materials and promote the continued circulation of materials. Thus, they support the principles of a circular economy, which aims to maximize the recycling and reuse of materials. Increasing the recycling rate of waste reduces the incineration and disposal of waste, which reduces the burden on the environment. In addition, the use of recycled aluminum in products reduces the need for mining and promotes adherence to the waste hierarchy. Both of the targets support increasing the use of recycled materials. The target related to aluminum supports it directly in the company's own operations, while the target to increase the recycling rate of waste supports it in the future by promoting the availability of recycled materials. Both of the sustainability targets belong to level 3 "recycling" of the waste hierarchy.[129] The targets are not required by legislation, but they sup

port, for example, the realization of the EU's recycling requirements for corporate waste. The company has not applied science-based frameworks, such as Science-Based Targets for Nature (SBTN), in setting the targets. Instead, the targets are based on scientific sources and expert recommendations, such as publications by the Ellen MacArthur Foundation. The target for the share of recycled aluminum is based on industry best practices and market requirements, where the regulatory framework, such as the effects of the CBAM Regulation on aluminum, is also one factor to consider.[130]

The waste recycling rate is monitored at the company's Finnish sites in Littoinen, Forssa and Tampere. Other sites do not generate significant amounts of waste. The target of increasing the waste recycling rate covers waste generated by the operations of these units. It therefore includes not only waste generated in production but also waste generated in the office. The methods and assumptions concerning the calculation of recycled aluminum are described in paragraph "Resource inflows, including resource use (E5-4)". The target of increasing the share of recycled aluminum in Teleste's products covers products both in the NET and the PSM business.[131] No changes have been made to the basis for preparation of the metrics over the specified time horizon.[132] The metrics have not been verified by an external party other than the company's sustainability reporting assurance provider.[133] The target of increasing the waste recycling rate is related to waste generated in the company's operations and, thus, resource outflows. The target of increasing the share of recycled aluminum

is related to purchased materials and, thus, resource inflows.

The company also monitors the number of suppliers who have made a commitment to the Supplier Code of Conduct, but no formal target has been set for this. The assumption behind the metric is that the more suppliers commit to sustainable practices, the more sustainable the company's supply chain becomes. Another assumption is that suppliers also require their subcontractors to comply with ethical principles. In 2025, 96% of the company's key suppliers have confirmed that they comply with Teleste's Supplier Code of Conduct. The company has also not set an official target or metric regarding the procurement of renewable raw materials.[134]

RESOURCES INFLOWS, INCLUDING RESOURCE USE (E5-4)

Material flows consist of finished products (amplifiers, workstations, servers and related products, tools, adapters, circuit boards, auxiliary materials) and raw materials used in production (semiconductor and passive components, mechanical parts, modules, packaging materials and electromechanical parts). The upstream value chain for their production mainly involves the following materials: metals (aluminium, copper, zinc, steel, brass, nickel), plastics, composites and other technical materials (glass fibre and resins, ceramics, quartz glass), chemical materials and solders and other materials (silicon, tools and adapters). Fixed assets used in the company's own operations include measuring devices, circuit analysers, circuit board cleaning equipment and various jigs. Water is not used in the manufacture of the company's own products. In

the upstream value chain, water is used in the production of raw materials, for example in connection with the production processes of circuit boards and components. The company does have precise visibility to the fixed assets used in the upstream value chain.[135]

The material weights of the components received in 2025 are obtained from ERP and product management systems. The predefined weight of each component is recorded in the system, which enables the calculation of the total weight of received components based on the quantities received during the year. In the design phase, material weights are verified either by direct measurements or by using information provided by the manufacturers, and they are recorded in the system. Components are classified into main categories and the material composition of each main category is documented.

The recycling rate of aluminum is based on data received from suppliers, on the basis of which the overall recycling rate has been calculated as 85%. The proportion of recycled aluminum used in the products is determined according to data reported by the suppliers.

For the NET business, the recycling rate applied for packaging material is 21%, which is based on the part number-specific information provided by the supplier. For pallets, purchased pallets are taken into account. For the NET business, pallets purchased in Finland and Belgium have been taken into account, and they are all 100% secondary use pallets at the time of purchase. Pallets received in connection with materials orders are reused in connection with customer deliveries. For orders of materials in the PSM business, recycled Euro pallets are used, in addition to which glass is delivered in wooden crates that are

not recycled. Euro pallets are 100% secondary use pallets when purchased. Customer deliveries are made partly using customer-specific pallets, which are purchased new, and partly using pallets received in connection with materials orders. Compared to the 2024 report, the weight of secondary reused or recycled components, secondary intermediary products and secondary materials shown in the table has been restated to correspond to the actual weight and recycling rate.

In the calculation of the total weight of materials, a distinction is made between technical and biological materials. All of the purchased products used in manufacturing are therefore included in technical materials. Technical materials include other materials except packaging materials (cardboard packaging) and wooden pallets, which are included in biological materials.^[137]^

For biological materials, the purchased pallets comply with the ISPM 15 standard. There is no certification system in place for packaging materials. Bio-based packaging is used according to the cascading principle so that its primary purpose is to package products. Once packaging is handed over to a customer, the materials are assumed to be directed to appropriate recycling. Wooden pallets usually circulate several times before they are taken out of use.^[138]^

Mass is calculated on the basis of the amount of incoming raw materials. The quantities of incoming materials are obtained directly from the ERP system, which ensures that double counting does not occur. A separate assessment has been made regarding pallets, as their weight and quantity are not directly monitored through the ERP system.^[139]^

OUTFLOWS RELATED TO PRODUCTS AND SERVICES (ES-5)

The most important products and materials that are outflows of the company's production process

Key products from the perspective of the use of materials in the NET business are telecom network products, such as broadband amplifiers and optical nodes. In the PSM business, the key products are displays in rail passenger cars and at stations, as well as other infotainment products installed on train, tram and metro systems. The products manufactured by Teleste are electronic devices consisting mainly of circuit boards containing electronic components, display panels, internal cables, power supplies, software, housings and other mechanical structures. Teleste's environmental policy sets the following targets for product design, for example:

  • The target is to extend the product life-cycle by improving the reliability, durability and serviceability of products.
  • Modular solutions support backward compatibility in product upgrades, thereby preventing unnecessary scrapping from customer systems.
  • Ease of dismantling and recyclability are taken into account in the early stages of design.

A checklist of adverse impacts is used in product creation projects. Teleste's end products cannot be remanufactured. They are designed to be dismantled as easily as possible into mono-materials. The devices are highly modular and support software updates that extend the product life-cycle. All

Table 16 Mean-Time-Between-Failures (MTBF) and mean target value for PSM product categories

Product category Calculated MTBF value Mean target MTBF
Display products 155,000 h 120,000 h
Audio system products 450,000 h 200,000 h
Other infotainment products 200,000 h 80,000 h

of the products are intended for professional use, which involves high requirements concerning quality and functionality. Maximizing the life-cycle of products is given significant attention in product design. There are hardly any side streams in the manufacture of the products. Teleste's products are manufactured to order, which means that the end products do not generate scrap material. All products go into production use, or are used as reserve equipment, by the customer.^[140]^

The expected durability of the products in relation to the industry average for each product group

The NET business manufactures telecom network products. For most of the products, the normal operating environment is an outdoor environment, which means that the temperature conditions in different geographical areas have a significant impact on the expected lifespan. No information is available on the average durability of products in the industry. At Teleste, the theoretical lifespan of PSM products is calculated using standard methods used in the electronics industry.

In the PSM business, especially for electronics products used in public transport, the MTBF (Mean-Time-Between-Failures) value is typically calculated according to the environmental conditions and operating hours of the customer project. Target values are typically also set for the products by the customer. As information is not generally available on the average durability of products in the industry, the average target values can be used as a benchmark. The table 16 shows the calculated MTBF values (as averages) and the average target values for the PSM product categories.^[141]^

Repairability of products

Part of the product creation process is an environmental review that takes the repairability of the product into consideration. Both businesses have their own versions of the checklist. Teleste's products have their own maintenance and spare parts service, which is available for at least seven years after official notification that the product will no longer be manufactured. The products are primarily designed to be openable, the parts are interchangeable, the products are highly modular and the software is upgradable. The target of serviceability is also documented in Teleste's environmental policy. There is no established classification system for the repairability of public transport and telecom equipment intended for professional use.

For repairable products in the PSM business, proactive maintenance measures are specified as needed, if necessary for ensuring the life-cycle of the product. Calculated on a mass basis, 50% of the products of Teleste's NET and PSM businesses were designed to be repairable.¹⁴²

Quantities of recyclable materials in products

In the NET business, amplifiers and optical nodes with die-cast housings are products that are relevant in terms of the manufactured quantities and mass. The housings are primarily made of recycled aluminum. In the PSM business, the thin metal housings of displays and other infotainment products used on trains and at stations are relevant products in terms of the manufactured quantities and mass. The thin metal used in the housings is partly made from recycled material. Correspondingly, the recyclable materials in the products mentioned above include all mechanical metal parts, cables and PCB materials. As a rule, the components of the products can be separated into mono-materials.

At the customer's request, PSM products are subject to a recyclability analysis, in which the amount of recyclable materials is determined by means of calculation. The calculation can be performed according to different standards (ISO 22628, ISO 21106, UNI-LCA-001). The calculation takes into account different material categories in accordance with the standards and generally all electronic components (circuit boards and display panels) are classified under electronics. For example, the recyclability figures extracted from the recyclability analysis of one TFT display product and one infotainment product according to different standards are provided in table 17. PSM products are similar electronic devices, so the example products can be considered to be representative of the entire PSM product portfolio.

The proportions of recyclable materials of products in the NET business in the calendar year 2025 have been calculated in accordance with the IEC/TR 62635 standard. Product examples representing high-volume products are provided in table 18.

The products of the NET business are similar electronic devices, so the example products can be considered to be representative of the entire NET product portfolio.¹⁴³

Waste streams

The waste generated by Teleste's operations is primarily non-hazardous waste. Very small amounts of hazardous waste are generated, and they are primarily recyclable.¹⁴⁴ The most significant proportion of the waste generated consists of packaging materials that are recycled. In addition, waste types typical of the industry, such as various types of metal, cable, electrical and electronic waste, are generated to some extent.¹⁴⁵

Most of the waste generated by Teleste's operations is cardboard and paperboard. In addition, clean untreated wood, which practically means pallets, and plastic make up the majority of packaging waste. Other materials present in waste include combustible waste that ends up in energy waste, aluminum and steel waste, electrical and electronic waste, cable waste, and recyclable paper and confidential paper waste.

The hazardous waste generated by the company's operations mainly consists of organic solid waste and aerosol waste.¹⁴⁶ The company's operations do not generate any radioactive waste.¹⁴⁷ At the company's sites in Littoinen, Forssa and Tampere, waste volumes are obtained from the waste management partners, which means that they are based on measurements. For the other units, waste volumes have been estimated on the basis of the best available data. The units for which waste volumes have been estimated are relatively small offices, which means that they do not generate significant amounts of waste. The waste volumes of small sites were estimated on the basis of the number of personnel. In the calculation, it was assumed that these sites generate small amounts of energy fraction and, in addition, waste fractions classified as recycled waste. The estimated data accounts for less than 5% of the total waste volume. Waste is monitored in the company's own waste accounting. The waste data in the tables covers the entire organization's waste, and the boundary therefore differs from the boundary applied in Teleste's sustainability target concerning the waste recycling rate.¹⁴⁸

MATERIAL IMPACTS, RISKS AND OPPORTUNITIES AND THEIR INTERACTION WITH STRATEGY AND BUSINESS MODEL (ESRS 2, SBM-3)

The impacts, risks and opportunities related to the company's own workforce (value chain: own operations) concern working conditions, equal treatment and equal opportunities. The policies, measures, metrics and targets presented in this section apply to all of the company's own personnel. Teleste has not identified any groups among its own personnel that would be particularly vulnerable to negative impacts.

  • Teleste's adheres to the principle of paying its personnel wages in accordance with the law and the applicable collective agreement. In addition, the company's compensation processes ensure equal pay for equal work, taking country-specific differences into account. Teleste is committed to promoting adequate and equal pay, as well as training and skills development, in all of its operating countries, thereby improving the well-being of its employees. The company monitors the wage development and wage level of its personnel, using human resources management processes to ensure that the minimum salary levels are exceeded in the various countries. In addition, Teleste's personnel mainly work in countries that have strict labor legislation and active supervision by the authorities. Some countries also have collective agreements in force, which, together with labor legislation, ensure employees' rights concerning pay. Teleste measures the ratio of the CEO's pay to the average pay of the employees and has set a target for it. The company also uses human resources management processes to ensure that these principles are complied with, and the company reacts to them as necessary.[152]

  • The company adheres to management principles that support work-life balance. Teleste offers its employees flexible working time arrangements, such as flexible working hours, remote work opportunities, parental leave and childcare opportunities, which helps to achieve a balance between work and private life. Teleste measures the employees' satisfaction with management through personnel surveys and develops its supervisors by means of coaching and training. Working time arrangements comply with country-specific labor legislation and any potentially applicable collective agreements, which help to ensure flexibility. In addition, Teleste's personnel-related operating procedures and policies aim to enable the reconciliation of work and free time. The corporate culture is measured in a personnel survey, and targets have been set for it. Management is also measured in the personnel survey, but no numerical target has been set for it.[153]

  • Teleste invests in the well-being of its employees in many different ways, ensuring good working conditions and health-related support measures. These support measures include, for example, comprehensive occupational health care and insurance policies that take country-specific differences into account. The company also supports the maintenance and development of mental and physical well-being by providing employee benefits that support this. A performance and development review is held annually with each employee, and well-being is one of the topics addressed. Corrective measures are established with regard to well-being as necessary. Teleste measures well-being and engagement, and clear targets have been set for these.[154]

  • The company's principles include equality and diversity. These topics are addressed in personnel training, including orientation training for new employees. The company's operating procedures and policies support the realization of these principles in recruitment and the monitoring of pay equality, for example. This creates an inclusive work community and improves the employer image. The company has also set a diversity target for the composition of the Board of Directors, the achievement of which is monitored.

As part of annually updated strategy, a human resources strategy is also drawn up, and it takes the company's personnel into consideration. The human resources strategy is the responsibility of the Senior Vice President, People and Culture, who is part of the Leadership Team. The company's business model and changes thereto take the personnel and human rights into account. The Senior Vice

President, People and Culture, is responsible for ensuring that these matters are taken into consideration as part of the development of the business model.^[155]^

Teleste's sustainability with regard to its own workforce is guided by the local legislation, collective agreements, the company's values, the human resources strategy and the company's personnel-related policies and operating procedures. Teleste's Code of Conduct is the highest-level policy guiding these matters. Teleste's operations are also guided by the Leadership Principles and the Culture Vision. These principles apply to everyone working at Teleste, regardless of the form of employment.

Teleste's various forms of employment include employees and non-employees, such as self-employed people and temporary agency workers. These workers can be either full-time or part-time, and the relationship may be either valid indefinitely or fixed-term.^[156]^

Teleste complies with local labor legislation and any collective agreements, which mitigates negative impacts and promotes positive impacts on Teleste's employees. In addition, 100% of the company's personnel are registered in the human resources management system, which reduces the risk of legal non-compliance with regard to the terms of employment or wages.

The People & Culture team conducts regular audits of personnel information systems and processes to ensure that they operate correctly. These operating practices are documented in operating procedures and policies, which are the subject of training for supervisors, for example. Teleste's personnel are also provided with extensive opportunities to report deviations.^[167]^

Teleste treats all employees with respect, fairness and equality. The company does not tolerate any form of racism or discrimination. The company's principle is that no one should be discriminated against due to age, origin, nationality, language, religion, conviction or opinion, political activity, trade union activity, family relationships, health status, disability, sexual orientation or other reason.^[168]^ Diversity and inclusion are the foundation of Teleste's way of working and thinking. Teleste's way of working means respecting all people and oneself. When they join the company, all Teleste employees complete onboarding training that covers diversity and inclusion, among other topics.^[169]^ Through various policies, operating procedures and processes, Teleste is comprehensively committed to ensuring that employees are not subject to negative impacts.^[170]^

Teleste has drawn up operating procedures titled "Equal and Fair Treatment SOP" and "Diversity & Inclusion SOP" to prevent discriminatory behavior and harassment in the company. The operating procedures also address the treatment of persons in vulnerable situations. In addition, the Recruitment SOP emphasizes a clear recruitment process that ensures equal opportunities for candidates to be employed at Teleste regardless of their background. These topics are covered

in orientation training and supervisor training, for example. The personnel also have the opportunity to raise concerns through various channels (including the whistleblowing channel and the personnel survey).^[171]^

Teleste adheres to the Teleste Group Health and Safety Policy. Any incidents related to occupational accidents are reported and corrective measures are taken based on them. The company also has in place processes that promote occupational safety, such as safety inspections and risk assessments, which are mentioned in the policy.^[172]^

Teleste engages in diverse dialogue with its employees. The company conducts a personnel survey twice a year and consults employees via the Employee Sounding Board forum.

PROCESSES FOR ENGAGING WITH OWN WORKERS AND WORKERS' REPRESENTATIVES ABOUT IMPACTS (S1-2)

Teleste's personnel is one of the company's most important assets. For this reason, Teleste has created a comprehensive system for decision-making, cooperation and communication between the company and its personnel. For example, the employee representative forum (Johtajisto) provides an opportunity for employee representatives to participate in decision-making with the company's management. These forums discuss topics such as management, culture, well-being, equality and pay (ESRS2 S1-RO1)^[174]^ . Teleste regularly collects feedback from its personnel and, at the same time, surveys development ideas that could have a positive impact on the personnel. Employee representatives are also met with on a regular basis through the following forums, among others: legally stipulated employer-employee cooperation (Finland), Employee Sounding Board (global), Johtajisto employee representative forum (global). Cooperation is carried out on a regular basis in accordance with an annual meeting planning calendar. Cooperation with employee representatives is carried out by the People & Culture department, and the company's Senior Vice President, People and Culture, participates in the cooperation, as does the CEO from time to time. In selecting the representatives for the Employee Sounding Board, the aim is for the forum to have as diverse a group of participants as possible. The members of other forums are selected by the personnel. The rate of engagement is assessed by means of the response rate of the personnel survey. Separate targets have been set for the response rate as part of the annual report.^[175]^

Teleste's personnel are not organized according to the European Works Council (EWC), Societas Europaea (SE) Works Council or Societas Cooperativa Europaea (SCE) Works Council models.^[176]^

Teleste measures the impact of its measures through the personnel survey process. The personnel survey is conducted using a system acquired for that purpose, which ensures the anonymity of the participants. Summaries of the survey results are published

for the personnel, and the summaries also specify measures to be taken. The personnel survey measures the following topics: 1) corporate culture, 2) leadership, 3) well-being and commitment. Employees also have the opportunity to give open feedback in the survey. The surveys are processed on a team-specific basis, at the Leadership Team level and with employee representatives. Teleste also monitors the development of sickness-related absences and the occupational accident frequency, and implements development measures based on them. An annual performance and development review is held with all Teleste employees to evaluate the planned and implemented measures. The company also addresses the personnel survey, myPulse results, the development of sickness-related absences and occupational accident statistics in various employee forums (including statutory employer-employee cooperation and the Johtajisto employee representative forum).^[177]^

tacting the company's People & Culture team or employee representatives. They can also use the whistleblowing channel. Employees can raise concerns through supervisors or employee representatives or by giving feedback in connection with personnel surveys, for example. The results of the personnel survey and the action plans drawn up on the basis of the results are submitted to the People & Culture team for analysis. They are used to prepare a summary that is presented to the Leadership Team for decision-making.[178]

The personnel survey response rate among Teleste's employees is fairly high, which is indicative of trust in this feedback channel.[179]

Reported concerns are only handled by the People & Culture team, which strives to protect the whistleblower's identity to the greatest possible extent in investigating the matter. Employees can also choose to use the anonymous whistleblowing channel.[180]

TAKING ACTION ON MATERIAL IMPACTS ON OWN WORKFORCE, AND APPROACHES TO MITIGATING MATERIAL RISKS AND PURSUING MATERIAL OPPORTUNITIES RELATED TO OWN WORKFORCE, AND EFFECTIVENESS OF THOSE ACTIONS (S1-4)

Through various policies, operating procedures and processes, Teleste is comprehensively committed to ensuring that employees are not subject to negative impacts due to working for the company.[181]

The key priorities of Teleste's human resources strategy are: 1) competence development, 2) good leadership, 3) a positive employee experience and 4) high-quality human resources management processes. Developing these areas is believed to increase

employee well-being and promote business growth. Measures that increase well-being help reduce the risk of losing key resources due to a deterioration of work-life balance.

Teleste's comprehensive occupational health care, comprehensive benefits that promote well-being at work and flexible working time arrangements improve well-being at work. In addition, the company's Nordic management style has been recognized as respecting the well-being of employees. Cooperation with employee representatives in various forums (Employee Sounding Board, statutory employer-employee cooperation forum, Johtajisto employee representative forum) and the Wellbeing and Engagement SOP, for their part, ensure that the well-being of the personnel is looked after.[182] Key projects have included training on Teleste's leadership principles and improving the corporate culture. Due to cost-saving measures, limited progress has been made on these. The performance and development review process supports dialogue between the employee and the supervisor.[183]

In 2025, to mitigate the identified negative impacts and promote the positive impacts, Teleste has offered its employees leadership and supervisor training, organized personnel surveys, carried out compensation reviews and invested in wellbeing at work, and the company will continue these measures in 2026.[184]

Teleste measures the impact of its measures through the personnel survey process. The personnel survey measures the following topics: 1) corporate culture, 2) leadership, 3) well-being and commitment. Employees also have the opportunity to give open feedback in the survey. In 2025, in addition to an extensive MyPulse survey for all of the personnel,

the company also conducted a more concise eNPS survey. The surveys are processed on a team-specific basis, at the Leadership Team level and with employee representatives. Teleste also monitors the development of sickness-related absences and the occupational accident frequency, and implements development measures based on them. An annual performance and development review is held with all Teleste employees to evaluate the planned and implemented measures. The company also addresses the results of the personnel survey, the development of sickness-related absences and occupational accident statistics in various employee forums (including statutory employer-employee cooperation and the Johtajisto employee representative forum).[185]

The company does not perceive any negative impacts on the personnel from the green transition, such as the closure of a manufacturing plant due to emissions-related reasons.[186]

TARGETS RELATED TO MANAGING MATERIAL NEGATIVE IMPACTS, ADVANCING POSITIVE IMPACTS, AND MANAGING MATERIAL RISKS AND OPPORTUNITIES (S1-5)

Teleste's key targets related to its own workforce are the engagement rate, improving the health rate and developing the corporate culture. Employee representatives have not been directly involved in setting the targets, but the company engages in active dialogue with them about the status of the targets and plans corrective measures. The status of these targets is discussed in Teleste's cooperation forums (statutory employer-employee cooperation, Employee Sounding Board and the Johtajisto employee representative forum). The achievement of the targets and related measures are discussed in various employee forums. In addition, the results of the personnel survey are discussed extensively in cooperation forums.[187]

CHARACTERISTICS OF THE UNDERTAKING'S EMPLOYEES (S1-6)

Key figures on the personnel are reported on the basis of data obtained from the personnel information system. The company's People & Culture team, the local HR unit and supervisors are responsible for keeping the information up-to-date. The key figures are reported in person-years at the end of the reporting period (31 December 2025) and as averages for the year. A person-year (FTE) describes an employee's work input relative to full-time hours. It is calculated by comparing an employee's contractual working hours with the company's normal full-time working hours. The figures include the entire Teleste Group's internal employees, but they do not include external workers or persons on long absences entered in the HR system. Employee turnover is calculated by comparing the number of employees who left the company during the year with the average number of person-years. Employee turnover covers all reasons for the termination of employment, and it is calculated by comparing the total FTE figure for employment relationships terminated during the reporting period with the FTE figure for the average number of employees during the reporting period. The monthly and annual averages are calculated by distributing the employees' working hours evenly over each calendar day during the period in question. The figures on remuneration are based on employees in an active employment relationship on 31 December 2025. The reported figures are consistent with the logic applied in the company's financial reporting.¹⁹⁰ The metrics related to the company's own workforce have not been verified by an external party other than the company's sustainability reporting assurance provider.¹⁹¹ Teleste's Group Leadership Team constitutes the senior executive management.¹⁹²

The targets related to own workforce apply only to Teleste's own personnel. Stakeholder representatives have not been involved in setting the targets. In setting the targets, efforts have been made to take account of the international policies and standards that are mentioned in the company's global human resources policy.¹⁹³

REMUNERATION METRICS (PAY GAP AND TOTAL REMUNERATION) (S1-16)

The total monthly salary of employees who were in an employment relationship with the company on 31 December 2025 was used to determine the pay gap. The pay gap was calculated by deducting the average gross monthly salary of women from the average gross monthly salary of men, and dividing that figure by the average monthly salary of men. The figure obtained was then converted into a percentage figure. The total remuneration ratio was calculated by dividing the salary of the highest paid individual in the company by the average annual total remuneration for all employees. The average annual total remuneration of employees was calculated by dividing the total personnel expenses for the reporting year by the average number of personnel during the year.

The topic of corruption and bribery is included in sustainability matters in accordance with the ESRS. Information security is a material sustainability theme for Teleste that is not covered by the ESRS and is reported on a voluntary basis. The materiality assessment is discussed in more detail in the following paragraph: Description of the processes to identify and assess material impacts, risks and opportunities (IRO-1).[212]

Business conduct policies and corporate culture (G1-1) (MDR-P, MDR-A)

The sustainability of Teleste's business conduct is guided by Teleste's Code of Conduct, which the company has further specified in its internal policies and guidelines. In accordance with these, the company is committed to complying with all applicable national and international laws and regulations and requires its suppliers and business partners to do the same. Teleste's Code of Conduct summarizes the principles of sustainable business conduct, such as honest and transparent business, anti-corruption, product quality and safety, human rights, the environment and whistleblowing. Teleste has been a member of the UN Global Compact network since 2023, and Teleste is committed to its policies and goals, which are aimed at sustainable development from the perspectives of the economy, human well-being and the environment.[213]

Teleste's governance structure supports sustainable business and a culture of doing the right thing at all levels. Responsibility for sustainable business conduct thus extends from the company's Board of Directors down to every employee. The members of Teleste's Leadership Team and the persons reporting to the members of the Leadership Team are responsible for ensuring that the company's policies are communicated appropriately and that their content is complied with. The company strives to ensure adherence to the culture of doing the right thing by providing training and online courses for the personnel, among

other things.²¹⁴ All of Teleste's personnel are required to complete online training on the Code of Conduct at the start of their employment and whenever the content is updated²¹⁵. In addition, Teleste aims to organize training especially for those individuals in the purchasing and sales organizations, for example, who are at the greatest risk of encountering situations involving corruption and bribery²¹⁶.

Together with its personnel, Teleste has defined the company's target culture, which is referred to as the Culture Vision. The personnel participate in various training activities concerning the corporate culture. Teleste's Leadership Team reviews the state of the company's corporate culture twice a year, in connection with addressing the other results of the personnel survey. In addition, the company's Board of Directors reviews the results of the personnel survey annually. The reviews focus on the development of the different components of Teleste's corporate culture and the necessary measures that may be initiated as necessary. As a technology company, Teleste considers innovation and job satisfaction to be particularly important, which is why resources in the human resources management function are allocated to analyzing these matters. Twice a year, the People & Culture team publishes an internal report that is aimed at the personnel and discusses the development of the corporate culture. Teleste's management aims to incorporate the key components of the corporate culture in its other communications, and the People & Culture team plans training activities aimed at promoting the corporate culture. Teleste's personnel have the opportunity to foster and develop the corporate culture by responding

to the personnel survey and giving feedback on the current situation.²¹⁷

Teleste's employees and other stakeholders are encouraged to raise concerns about potential misconduct in Teleste's business or other functions related to the company. Teleste's employees can always contact their supervisor or a member of Teleste's Leadership Team in case of suspected misconduct. In addition, the whistleblowing channel ensures that whistleblowers can raise concerns anonymously. The whistleblowing channel is available to the company's employees and external stakeholders on Teleste's website.²¹⁸

The company is committed to investigating all whistleblower reports that are made in good faith and protecting the privacy of the whistleblower. The whistleblower is not at risk of losing their job and will not face any other consequences if they report a genuine suspicion. In potential criminal cases, the whistleblower's identity may need to be disclosed in connection with legal proceedings.²¹⁹

Teleste's Ethics & Compliance function investigates suspected misconduct reported by business units or Group functions. The Ethics & Compliance function reports significant suspicions of misconduct or violations to the Audit Committee of the Board of Directors. Only the members of the whistleblowing team, who are designated by the Ethics & Compliance and have received training from the company's legal department, have access to reports received through the whistleblowing channel. Their actions are logged and all of their actions are confidential. The whistleblowing team may request other persons to participate in the investigation process if that is necessary for investigating the matter.

Such persons only have access to information that is relevant to the investigation and are also subject to confidentiality. Persons who are the subject of the suspected misconduct or who have connections to the case never participate in the investigation. Depending on the case, the results of the investigation process are reported to the company's CEO or the Chairman of the Audit Committee, and they decide on what actions will be taken to remedy the situation. The whistleblower is also informed of the results of the investigation, taking into account, however, the protection of the privacy of the persons who are the subject of the report and other matters related to confidentiality.²²⁰

PREVENTION AND DETECTION OF CORRUPTION AND BRIBERY (G1-3)

Teleste is committed to the UN Global Compact initiative and has confirmed its principles and approach towards corruption and bribery in the company's Code of Conduct. In addition to complying with the Code of Conduct, each employee of the company is required to adhere to the anti-corruption policy approved by the company's Board of Directors. The

anti-corruption policy includes the prohibition of corruption and bribery, as well as anti-corruption principles regarding gifts, hospitality and the avoidance of conflicts of interest. The content of the anti-corruption policy is also communicated to Teleste's customers, suppliers and other stakeholders. Suspected incidents of corruption and bribery are investigated and the results are reported in accordance with the policies described above in the section "Business conduct policies and corporate culture".²²¹

In 2025, Teleste updated its Code of Conduct and the related online training. The online training on the Code of Conduct covers 100% of the activities that are at the highest risk of exposure to corruption and bribery. In addition, the members of Teleste's Leadership Team have received training on the content of the anti-corruption policy by the policy owner. The members of Teleste's Leadership Team and the persons reporting to the members of the Leadership Team are responsible for ensuring that the company's policies, including the anti-corruption policy, are communicated appropriately and that their content is complied with.²²²

INCIDENTS OF CORRUPTION OR BRIBERY (G1-4)

There were no confirmed incidents of corruption or bribery in 2025. For this reason, it has not been necessary to implement measures to address violations of anti-corruption and anti-bribery procedures and norms.²²⁴

METRICS AND TARGETS (MDR-T)

The target of Teleste's culture development effort is to build a consistent and strong organizational culture for the company. The company is of the view that a strong culture will promote employee engagement, enhance well-being at work and encourage innovation. Ultimately, the company believes that strong culture that is present in all of the work it does will also be reflected in customer relationships by strengthening them and leading to even stronger performance.²²⁵

The realization of the corporate culture is measured every six months as part of the company's personnel survey, and a sustainability target has been set for it. The target related to corporate culture is described in more detail in the section "Targets related to managing material negative impacts, advancing positive impacts, and managing material risks and opportunities" (S1-S). The company assesses the effectiveness of the online training on the Code of Conduct on the basis of the completion rate of the training. The target was for all of the company's personnel to complete the new online training course on the Code of Conduct in 2025. The company does not have metrics or official sustainability targets concerning the management of other governance-related impacts, risks or opportunities identified as material in the materiality assessment.²²⁶

INFORMATION SECURITY

Teleste respects privacy and is committed to protecting the privacy, confidentiality and information security of both the company's and its stakeholders' data. In connection with the double materiality assessment carried out in 2025, information security and, in particular, the risk of a cyber attack were identified as a new material theme. A successful cyber attack could lead to internal or external data leaks or business disruptions.

Information security is an entity-specific sustainability theme, but the assessment of the related impacts, risks and opportunities has been carried out as part of the company's double materiality assessment, which is described in more detail in the section "Impact, risk and opportunity management".

Policies

Information security has been extensively taken into account in Teleste's policies and operating guidelines. Information security and data protection are an integral part of Teleste's Code of Conduct and security policy. The company also has separate information security instructions. Information security requirements have also been incorporated into Teleste's Supplier Code of Conduct. The security policy, information security guidelines and Supplier Code of Conduct are approved at the Leadership Team level. Teleste's Code of Conduct is approved by Teleste's Board of Directors.

The key objective of the security policy is to enable the appropriate protection of Teleste's and customers' assets. The policy covers the following areas of security:

  1. security management and administration,
  2. the safety of the personnel,
  3. physical security and the security of facilities, and
  4. information and cyber security.

The security policy and the security management system cover all Teleste Group companies and all countries in which Teleste operates.

The information security guidelines include Teleste's official instructions, procedures and requirements, the purpose of which is to enable the appropriate protection of data and information systems. The guidelines establish a framework for the secure and appropriate use of data and IT resources and allocate responsibilities to the right parties. The guidelines also take into account data integrity and data classification perspectives.

Teleste's Code of Conduct contains the main principles concerning information security. The Supplier Code of Conduct imposes information security-related requirements on suppliers.

Measures

Teleste has processes, practices, software and hardware in place to ensure the secure, appropriate and correct handling of confidential information and personal data. The company has an effective cyber security system that protects information systems and networks from information security threats.

In the fall of 2025, the company started a certification process for its ISO 27001-compliant information security system. ISO 27001 is an internationally recognized information security standard that provides a systematic approach to information security management. A team of experts has been assembled for the development project of the certified system, consisting of representatives from both of Teleste's business units, the information management function and the quality and sustainability team. The information security system will be integrated into Teleste's existing processes and certified quality management system.

Teleste's personnel are provided with regular training on matters related to information security and data protection. Online training courses on information security and cyber security are mandatory for all employees.

Security, including information security, is part of Teleste's Group-level risk management system.

Metrics and targets

Teleste started a certification process for its ISO 27001-compliant information security system in the latter part of 2025. Teleste's target is to achieve certification for its ISO 27001-compliant information security management system during 2026. More detailed Group-level targets and metrics related to information security will be established as part of the development project related to the certification of the system.²²⁷

Notes to the Consolidated Financial Statements

1. ACCOUNTING PRINCIPLES FOR THE CONSOLIDATED FINANCIAL STATEMENTS

COMPANY PROFILE

Teleste Corporation (the "Company") is a Finnish public limited liability company organised under the laws of Finland and domiciled in Turku in Finland. Its registered address is Telestenkatu 1, 20660 Littoinen. Founded in 1954 Teleste is a technology company running business activities, with a focus on the product solutions for video service platforms and video surveillance applications for broadband subscriber networks, as well as comprehensive service solutions, such as network construction, renewal and maintenance, maintenance and design services. The parent company of Teleste Group, Teleste Corporation, has permanent establishment in Netherlands and a subsidiaries in twelve countries outside Finland. Teleste Corporation has been listed on the Helsinki Stock Exchange since 1999. A copy of the consolidated financial statements can be obtained either from Teleste's website www.teleste.com or from the parent company's head office, the address of which is mentioned above.

STATEMENT OF COMPLIANCE

These financial statements have been prepared in accordance with International Financial Reporting Standards (IFRSs) in force as at 31 December 2025. International financial reporting standards, referred to in the Finnish Accounting Act and in ordinances issued based on the provisions of this Act, refer to the standards and their interpretations adopted in accordance with the procedure laid down in regulation (EC) No 1606/2002 of the EU. The notes to the consolidated financial statements also include additional information in accordance with the Finnish accounting and company legislation.

The Finnish version of the financial statements are prepared and published in such a way that they meet the requirements of the ESEF RTS. ESEF financial statements are published in XHTML format in accordance with ESEF RTS. The ESEF financial statements have certified by an audit company PricewaterhouseCoopers.

Teleste Group has changed its consolidated financial statement preparation principles in 2025. The effects of external exchange rates not under hedge accounting are recorded in financial items, regardless of which item the exchange rate difference originates from. The figures for the financial year 2024 have been adjusted to correspond to the preparation principles of 2025. Otherwise, the consolidated financial statements have been prepared according to the same principles as in 2024. The IFRS standards or their amendments that came into effect in 2025 have not had an impact on the company's financial statements for 2025.

BASIS OF PREPARATION

The consolidated financial statements are presented in thousands of euro (TEUR) and have been prepared under the historical cost convention, unless otherwise stated in the accounting principles.

USE OF ESTIMATES

The preparation of financial statements in conformity with IFRSs requires management to make estimates and assumptions that affect the contents of the financial statements as well as use judgement when applying accounting principles. The estimates and assumptions are based on the management's current best knowledge reflecting historical experience and other reasonable assumptions. Actual results may differ from these estimates. Accounting estimates mainly relate to activated development costs, goodwill, obsolete inventories, credit losses, deferred taxes and warranty provisions. The chapter "Accounting policies requiring management's judgement and key sources of estimation uncertainty" discusses judgements made by management and those financial statement items on which judgements have a significant effect.

SUBSIDIARIES

Subsidiaries include all such companies (including structured entities) in which the group has control. The group has control over a company when it is exposed to or has rights to variable returns from its involvement with the company and has the ability to affect those returns through its power over the company's activities. Subsidiaries are consolidated in the group's financial statements in full from the date the group obtains control. Consolidation is terminated when control ceases.

ASSOCIATES

At the end of the reporting period the Group had no investments in associates.

Report of the Board of Directors

Group

Parent company

Shares and shareholders

JOINT VENTURES

At the end of the reporting period the Group had no joint ventures

PRINCIPLES OF CONSOLIDATION

Acquisitions of companies are accounted for by using the purchase method. All intercompany income and expenses, receivables, liabilities and unrealised profits arising from intercompany transactions, as well as distribution of profits within the Group are eliminated as part of the consolidation process. The allocation of the profit for the period attributable to equity holders of the parent company and non-controlling interest is presented on the face of the income statement and the non-controlling interest is also disclosed in the statement of comprehensive income. Non-controlling interests are disclosed separately under consolidated total equity.

SEGMENT REPORTING

Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision maker. At Teleste Corporation, the Board of Directors of the parent company acts as the chief operating decision maker.

FINANCIAL STATEMENTS OF FOREIGN SUBSIDIARIES

The functional currency of the parent company is euro and the consolidated financial statements are presented in euro. The functional currency is the currency that best reflects the economic substance of the underlying events and circumstances relevant to that entity. In preparing the consolidated financial statements income statements and cash flows of those foreign subsidiaries whose functional and presentation currency are not the euro, are translated into euro at the average exchange rate during the financial period. Their balance sheets are translated at the closing rate at the balance sheet date.

All translation differences arising from consolidation of foreign shareholdings are recognised as a separate item in the comprehensive income. If an interest in a foreign entity is disposed of all, or part of, that entity, related cumulative translation differences deferred in equity are recognised in the income statement as part of the gain or loss on sale.

FOREIGN CURRENCY TRANSACTIONS

Transactions in foreign currencies are translated at the rates of exchange prevailing on the dates of the transactions. At the end of the accounting period, foreign currency monetary balances are translated at the closing rate at the balance sheet date. Non-monetary items stated at fair value in a foreign currency are translated at foreign exchange rates ruling at the dates the fair value was determined. Other non-monetary items are translated using the exchange rate at the date of the transaction. Gains and losses resulting from transactions in foreign currencies and translation of monetary items are recognised in the income statement. Foreign exchange gains and losses on trade payables are adjusted to re operating expenses. Other foreign exchange gains and losses are presented as financial income and expenses.

PROPERTY, PLANT AND EQUIPMENT

Items of property, plant and equipment are stated at historical cost less cumulative depreciation and any impairment losses. Where parts of an item of property, plant and equipment have different useful lives, they are accounted for as separate items of property, plant and equipment. Interest costs which are directly attributable to the acquisition, construction or manufacturing of an asset that meets the determined criteria, in which case they are capitalized as part of the cost of that asset. Ordinary maintenance, repairs and renewals are expensed during the financial period in which they are incurred. In Teleste there are no such significant inspection or maintenance costs that should be capitalised. The Group recognises in the carrying amount of an item of property, plant and equipment the subsequent costs when that cost is incurred if it is probable that future economic benefits in excess of the originally assessed standard of performance of the existing asset will flow to the Group and the cost of the item can be measured reliably. Such renewals and repairs are depreciated on a systematic basis over the remaining useful life of the related asset. Gains and losses on sales and disposals are calculated as a difference between the received proceeds and the carrying amount and are included in other operating income and expenses, respectively.

Depreciation is charged to the income statement on a straight-line basis over the estimated useful lives of each part of an item of property, plant and equipment. Expected useful lives and residual values of non-current assets are reassessed at each balance sheet date and where they differ from previous estimates, depreciation periods are changed accordingly. The estimated useful lives are as follows:

  • Buildings 25–33 years
  • Machinery and equipment 3–5 years
  • Computers 0–3 years
  • Software 3 years
  • Land is not depreciated.

LEASES

Teleste has applied IFRS 16 Leases from 1 January 2019.

GROUP AS LESSEE

Assets leased by Teleste that are not subject to exception available in IFRS 16 are recognized in the balance sheet at the inception of the lease as a non-current asset and a lease liability. The property, plant and equipment is amortized over the lease term and any impairment losses are recognized. Lease liabilities are included in the Group's current and non-current financial liabilities. Lease costs arising from leases are divided into interest expense and lease repayment. Repayment of a lease liability is recognized in the cash flow statement in the cash flow from financing activities.

Lease terms are negotiated on case by case basis and are subject of wide variety of terms. Lease agreements do not contain any other covenants besides the lease subjects security interest.

Teleste applies the exception available allowed by the standard for short-term leases and leases of low value assets.

INTANGIBLE ASSETS

An intangible asset is recognised only when it is probable that future economic benefits that are attributable to the asset will flow to the Group and if the cost of the asset can be measured reliably. All other expenditure is expensed as incurred.

Goodwill

Goodwill represents the Group's share of the difference between the acquisition cost and the fair value of identifiable assets, liabilities, and contingent liabilities acquired, as mea

sured at the acquisition date. Goodwill is allocated to the cash-generating units that benefit from the acquisition. Goodwill is measured at original cost less any accumulated impairment losses. Goodwill (and other intangible assets with indefinite useful lives) are not amortized but are assessed annually for possible impairment through impairment tests.

Research and development costs

Research and development costs are expensed as they are incurred, except for certain development costs, which are capitalised when IFRS criteria are met. Significant future product platforms for which the potential demand and future cash flows can be estimated with sufficient degree of accuracy have been capitalised as intangible assets. Amortisation of such capitalised development projects is commenced after the completion of the subprojects related to the product platform concerned. They are amortised on a systematic basis over their expected useful life, which is from three to five years.

Other intangible assets

Other intangible assets of the Group mainly consist of intangible assets created from business acquisitions.

Those intangible assets which have estimated useful lives are depreciated on a straight-line basis over their known or estimated useful lives. The estimated useful lives are as follows:

  • Customer relationships 2-4 years
  • Trademarks 5-10 years
  • Technology 3-5 years

NON-CURRENT ASSETS HELD FOR SALE AND DISCONTINUED OPERATIONS

A non-current asset (or disposal group) is classified as held for sale when its carrying amount will be recovered principally through a sale transaction rather than through continuing use. It is measured at the lower of carrying amount and fair value less costs to sell. Such assets and associated liabilities are presented separately in the balance sheet. Assets held for sale are not depreciated (or amortised) after the classification as held for sale.

A discontinued operation is a component of the Group's business that represents a separate major line of business or a geographical area of operations or is a subsidiary acquired exclusively with a view to resale. The result of discontinued operations is presented separately on the face of the consolidated income statement.

IMPAIRMENT

The carrying amounts of assets are assessed for potential impairment at each balance sheet date and whenever there is any indication that an asset may be impaired. For the purposes of assessing impairment, assets are grouped at the cash generating unit level, which is the lowest level for which there are separately identifiable, mainly independent, cash inflows and outflows. Goodwill, unfinished intangible assets and intangible assets with indefinite useful lives, if any, are in all cases tested annually. All goodwill items of the Group have been allocated to cash generating units. If there is an indication of an impairment, the Group estimates the recoverable amount of the asset or cash generating unit. When the recoverable amount of the asset or cash generating unit is lower than the carrying amount, the difference is immediately recognised as

an impairment loss in the income statement. If the impairment loss is to be allocated for a cash-generating unit, it is allocated first by writing down any goodwill and then on pro rata basis to other assets of the unit.

The recoverable amount is the higher of an asset's or cash generating unit's fair value less costs to sell or value in use. Teleste has applied value in use in its calculations in which case the estimated future net cash flows expected to be derived from the asset or cash generating unit are discounted to their present value. Expenditures to improve assets' performance, investments or future restructurings are excluded from the cash flow estimates.

An impairment loss relating to property, plant and equipment and other intangible assets excluding goodwill is reversed if there is an indication that the impairment loss may no longer exist and there has been a positive change in the estimates used to determine the recoverable amount of an asset or cash generating unit. An impairment loss is only reversed to the extent that the asset's carrying amount does not exceed the carrying amount that would have been determined, net of depreciation or amortisation, had no impairment loss been recognised for the asset in prior years. However, an impairment loss in respect of goodwill is never reversed.

INVENTORIES

Inventories are stated at the lower of cost or net realisable value. Cost is assigned by using the first-in, first-out (FIFO) method. Net realisable value is the estimated selling price in the ordinary course of business, less the estimated costs of completion and the estimated costs necessary to make the sale. The cost of inventories comprises all direct

costs incurred in acquiring the inventories and bringing them to their existing location and condition. In the case of manufactured inventories and work in progress, cost includes an appropriate share of overheads based on normal operating capacity.

FINANCIAL ASSETS AND LIABILITIES

Rahoitusvarat

Financial assets are classified according to the assets and the assets' contractual cash flow characteristics as follows:

  • assets measured at amortised cost
  • assets measured at fair value through other comprehensive income and
  • assets measured at fair value through income statement.

The classification is made on the basis of the objective of the contractual cash flows of the investment or by applying the fair value option at the time of the original acquisition.

Purchases and sales of financial assets are recognised on the transaction date, which is the date on which the Group commits to purchasing or selling the financial instrument. At initial recognition, the Group measures financial assets at fair value. If the asset is not an asset measured at fair value through income statement, transaction costs caused directly by the asset are added to or deducted from the asset. Transaction costs are included in the original carrying amount of financial assets in the case of items not measured at fair value through income statement. Financial assets measured at fair value through income statement are recognised on the balance sheet at initial recognition, and transaction costs are recognised through income statement.

Financial assets measured at amortised cost

Financial assets measured at amortised cost include financial assets that according to the business model are to be held until maturity in order to collect contractual cash flows. The cash flows of these items consist fully of capital and interest related to the remaining capital.

After initial measurement, the value of these financial assets is measured at amortised cost using the effective interest rate method less any impairment. The Group recognises the loss allowance on expected credit loss for an asset measured at amortised cost. Expected credit losses are presented under the income statement item impairment of financial assets. Losses due to impairment are taken to the income statement.

The Group's financial assets measured at amortised cost include trade receivables and other receivables that are non-derivative financial assets. The carrying amount of current trade and other receivables is considered to equal their fair value. Trade and other receivables are presented on the balance sheet as current assets if they are expected to be realised within 12 months of the end of the reporting period.

For trade receivables, the so-called simplified approach according to IFRS 9 is used to estimate expected credit losses, whereby credit losses are recognized for the entire duration of the receivable. Impairments are based on the expected credit loss model. To determine expected credit losses, trade receivables are grouped by age category. Trade receivables do not contain a significant financing component. Credit losses recognized as expenses in the income statement are included in other operating expenses. Expected credit losses are assessed based on historical data on previous credit losses and an estimate of future outlooks.

Financial assets measured at fair value through other comprehensive income

The Group's financial assets measured at fair value through other comprehensive income consist of investments in non listed shares.

Profit or loss on items measured at fair value through other comprehensive income is recognised in other comprehensive income. Changes in fair value are not reclassified through profit and loss. Dividends are presented in profit and loss.

Financial assets measured at fair value through profit or loss

Other financial assets are measured at fair value through profit or loss. Financial assets held for trading purposes have mainly been acquired to obtain a gain in the short or long term, and they are shown in non-current or current financial assets. The Group's financial assets measured at fair value through profit or loss consist of shares and derivatives where hedge accounting is not applied.

Gains and losses arising from a change in fair value, realised or unrealised, are recognised through profit or loss. If investments do not have quoted prices, the Group applies different methods of valuation to them. Unquoted shares are valued at the lower of acquisition cost and probable transfer price.

Cash and cash equivalents

Cash and cash equivalents consist of cash on hand, demand deposits in banks, and other short-term, highly liquid investments that are readily convertible to known amounts of cash and which are subject to an insignificant risk of changes in value. Items classified as cash and cash equivalents have a maturity of no more than three months from the date of acquisition. Overdraft accounts are included in either short-term or long-term financial liabilities according to their maturity.

Recognition of final credit loss

Group uses the IFRS 9 simplified for expected credit loss related to trade receivables. In the simplified approach, the recognised amount of credit losses covers all the credit losses expected during the validity period.

Credit losses are determined using a provision matrix in which trade receivables are grouped based on their aging.

Credit loss raters are based on payment profiles from 48 months before 31 December 2020 and any final credit losses during that period. Calculated credit loss rates are adjusted to take into account the current situation. All trade receivables overdue 360 days or more are recognized as credit loss. Financial assets are written of the balance sheet as final credit losses.

Derecognition of financial assets

Financial assets are derecognised from the balance sheet when the Group's contractual right to the cash flows has expired or has been transferred to another party, or when the risks and rewards of ownership have to a significant degree been transferred outside the Group.

Financial liabilities

Financial liabilities have been classified according to IFRS 9 into the following categories:

  • financial liabilities measured at amortised cost
  • financial liabilities measured at fair value through income statement.

Financial liabilities are initially recognised at fair value. Excluding financial liabilities measured at fair value through profit or loss, financial liabilities are later measured at amortised cost using the effective interest rate method. Transaction costs are included in the initial carrying amount of financial liabilities measured at amortised cost. Transaction costs related to financial liabilities measured at fair value through profit or loss are recognised as expense.

The Group's financial liabilities consist of leasing and bank loan liabilities.

On the Group balance sheet, financial liabilities may be included in both non-current and current liabilities. Financial liabilities are classified as current if they mature in less than 12 months and the Group does not have an unconditional right to defer payment for at least 12 months from the end of the reporting period.

Derecognition of financial liabilities

Financial liabilities are derecognised from the balance sheet when the liability has ceased to exist, that is, an obligation specified in the contract has been fulfilled or cancelled, or it has expired.

Treasury shares

Teleste Corporation's own shares acquired by the Group, including directly attributable costs, are presented as a deduction from total equity in the consolidated financial statements. Purchases or subsequent sales of treasury shares are presented as changes in equity.

Dividends

The dividend proposed by the Board of Directors is not recognised until approved by a general meeting of shareholders.

Provisions

A provision is recognised in the balance sheet when the Group has a present legal or constructive obligation as a result of a past event, a reliable estimate can be made of the amount of the obligation and it is probable that an outflow of economic benefits will be required to settle the obligation. The amount recognised as a provision is the best estimate of the expenditure required to settle the present obligation at the balance sheet date. If the effect of the time value of money on the amount of a provision is material, a provision is discounted. Provisions can arise from warranties, onerous contracts and restructurings. A warranty provision is recognised when the underlying products are sold. The provision is based on historical warranty data and an estimate. A reimbursement from a third party related to a provision is recognised as a receivable only when the reimbursement is virtually certain.

A provision for restructuring is recognised when the Group has a detailed and formal restructuring plan, and the restructuring has either commenced or has been announced publicly to those it concerns. The plan identifies at least the following: the business concerned, the principal locations affected, the location, function, and approximate number of employees who will be compensated for terminating their services, the expenditures that will be undertaken and when the plan will be implemented. Future operating costs are not provided for.

Revenue recognition and net sales

Revenue is recognised at a point in time or over time. The performance obligations is typically satisfied when goods are delivered and services are performed. Revenue from the sale of goods is recognised in the income statement when all significant risks and rewards of ownership have been transferred to the buyer, which normally takes place when a commodity is delivered. Revenue from services is recognised when the service has been performed. Typical payment term to customer is 30 to 90 days from invoicing data. Payment term over 12 months doesn't exist. Teleste is granting normal warrants in this business for its products. Defects in Teleste products caused by design, bad material or manufacturing are repaired or replaced by new products. There is no sale with a right of return. Costs of obtaining customer contract are capitalized when they exist. Revenue recognition process does not include any substantive discretionary items.

Revenue from contract assets is recognised by applying the cost-to-cost method of accounting as the measurement basis. Revenue and profits are recognised after considering the ratio of cumulative costs incurred to estimated total costs to complete each contract (the stage of completion). Recognition of profit requires the outcome of a construction contract be estimated reliably. If this is not the case, revenue is recognised only to the extent of contract costs incurred that it is probable will be recoverable; and contract costs are expensed in the period in which they are incurred. In the event that the Group can be held as the main contractor of a construction contract, various product expenses including raw materials and labour costs will be accounted for in the calculation of the stage of completion. Possible changes in the expected total expenses of a construction contract are expensed as incurred. The expected loss is charged to the income statement immediately.

If costs incurred together with recognised profits exceed the amount billed, the difference is included in the balance sheet item "trade and other receivables". When costs incurred together with recognised profits are lower than the amount billed, the difference is shown under "trade and other payables".

Net sales include revenue from services rendered and goods sold, adjusted for discounts granted, sales-related taxes and effects of the translation differences.

Other operating income

Other operating income comprises income not generated from primary activities, such as gains from disposal of assets.

Government grants

Government grants that compensate the Group for expenses incurred are recognised as revenue in the income statement on a systematic basis in the same periods in which the expenses are incurred. Grants that compensate the Group for the cost of an asset are recognised by deducting the grant from the carrying amount of the asset.

Employee benefits

Pension arrangements

Pension plans are classified as either defined contribution plans or defined benefit plans. The plans the Group has currently are classified as defined contribution plans. Contributions to defined contribution pension plans are recognised as an expense in the income statement in the year to which they relate. The statutory pension plans of Finnish subsidiaries in the Group are funded through pension insurance. Subsidiaries outside Finland have various pension schemes in accordance with local requirements and practices.

Share-based payments

Groups long term incentive plans share-based payments are measured at their fair values using the Monte Carlo pricing model at the grant date and are recognised as an employee expense during the vesting period with a corresponding increase in equity.

Operating profit

Operating profit is not defined under IAS 1 Presentation of Financial Statements. In Teleste it is defined as a net amount that is comprised of the following items:

net sales

  • other operating income
  • raw material and consumables used adjusted for changes in inventories of finished goods and work in progress
  • employee benefits expense
  • depreciation and amortisation expense and impairment losses
  • other operating expense
    = operating profit / loss

All other items not mentioned above are presented under the operating profit. Exchange rate differences relating to sales and purchases are treated as adjustments to these items. All other exchange rate differences are included in financial income and expenses.

Borrowing costs

Borrowing costs are generally expensed in the period in which they are incurred, except if they are directly attributable to the construction of an asset that meets the determined criteria, in which case they are capitalized as part of the cost of that asset.

Interest and dividend income

Interest income is recognised using the effective interest method. Dividend income is recognised when the right to the dividend has established.

Derivative instruments

Derivatives are initially recognized at fair value on the date a derivative contract is entered into and are subsequently measured at fair value at the end of each reporting period. The accounting for changes in fair value depends on whether the derivative is designated as a hedging instrument and the nature of the item it hedges.

If hedge accounting is not applied to the derivative, changes in fair value through profit or loss are recognized in the income statement to adjust the corresponding expense item.

At the inception of the hedge, the financial relationships between the hedging instruments and the hedged items and whether changes in the cash flows of the hedging instruments are expected to offset the changes in the cash flows of the hedged items, are documented. In addition, the objectives of risk management and the strategies according to which hedging measures are taken are documented.

When a non-financial asset (such as inventories) is subsequently recognized as a hedged item, both the unrecognized hedge gains and losses and the time or forward points not recognized in profit or loss are included in the asset's original acquisition cost. These amounts are finally recognized in profit or loss when the hedged item affects profit or loss.

When a hedging instrument expires or the instrument is sold or terminated, or when the hedge no longer meets the criteria for hedge accounting, the gain or loss currently recognized in equity and the unrecognized hedging expense remain in equity until the expected transaction takes place and as a result, a non-financial asset, such as inventories, is recognized. If the forecast transaction is no longer expected to occur, the cumulative gain or loss recognized in equity and the hedging costs are transferred immediately to profit or loss.

Income taxes

The income taxes in the consolidated income statement consist of current tax and the change in the deferred tax assets and liabilities. Current tax includes taxes of the Group companies calculated on the taxable profit for the period determined in accordance with local tax rules, as well as the tax adjustments related to previous years. Deferred tax relating to items charged or credited directly to comprehensive income is itself charged or credited directly to comprehensive income and equity.

Deferred tax assets and liabilities are provided in the consolidated financial statements using the balance sheet liability method, providing for all temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. The main temporary differences arise from the treatment of development costs, the depreciation difference on property, plant and equipment and effects of consolidation and eliminations. Deferred taxes are not provided for impairment of goodwill, which is not deductible for tax purposes, nor for undistributed profits of subsidiaries to the extent that it is probable that the temporary difference will not reverse in the foreseeable future. Deferred tax liabilities are recognised at their full amounts in the balance sheet, and deferred tax assets are recognised at estimated realisable amounts. The enacted or substantially enacted tax rate at the balance sheet date is used as the tax rate.

Accounting policies requiring management's judgement and key sources of estimation uncertainty

Management's assessment of capitalized development expenditures, goodwill, obsolete inventory, credit losses, deferred taxes, and warranty provisions is based on accepted accounting models and case-specific judgment. Case-specific judgment has utilized the best available information at the time of preparing the financial statements.

The cash flow-based value in use of goodwill is determined as part of a cash-generating unit by calculating the estimated future discounted net cash flows from the cash-generating unit. The budget and long-term plans approved by management form the basis for the forecasted cash flows. The key uncertainties in the value-in-use calculations are the forecasts used. Detailed information on goodwill testing is provided in Note 10.

Inventory valuation using the FIFO method at the lower of cost or net realizable value is based on either specific consumption-based accounting or, alternatively, age-based accounting which can also reflect management's view of market conditions. The uncertainties primarily relate to changes in the market conditions of products, as the potential market for individual products is often limited. The inventory provision is presented in Note 14.

Expected credit losses are assessed based on historical data on past credit losses and an assessment of future prospects. The uncertainties relate to customers' payment behavior and financial situation. Historically, the Group has not experienced significant credit losses, and a portion of trade receivables are secured by credit insurance or receivables financing. The breakdown of the credit loss provision for trade receivables is presented in Note 15.

In terms of deferred taxes, management's judgment is mainly applied to the recognition of deferred tax assets from tax losses. The recognition of deferred tax assets considers the respective company's forecasts, history, potential changes in cost structure, the amount of accrued losses, and their expiration period. Tax loss carryforwards recognized as deferred tax assets are presented in Note 13.

The Group's warranty provision is based on the average warranty period granted for its products and historical experience with defective products. The amounts of the warranty provision are disclosed in Note 19.

By the time of the disclosure of the consolidated financial statements, Teleste has not received any information on significant uncertainties or key future assumptions regarding the estimates as of the balance sheet date that would pose a significant risk of material changes in the carrying amounts of assets and liabilities within the next period.

Adoption of new and amended standards and interpretations applicable in future financial years

Teleste has not yet adopted the following new and amended standards and interpretations already issued by the IASB. The Group will adopt them as of the effective date or, if the date is other than the first day of the financial year, from the beginning of the subsequent financial year.

The Group has not adopted the published new accounting standards, changes to accounting standards, and interpretations that are not mandatory for the financial years ending on December 31, 2025.

Teleste has started investigations into the effects of IFRS 18, which will be applied starting in 2027, on the presentation of the company's financial statements. Although the adoption of the standard is likely to have a significant impact on the presentation of the financial statements, according to the investigation, the standard will not have a material effect on the key figures reported by the company, such as operating profit, net result for the financial year, or operational cash flow.

Regarding other changes, the Group does not expect the standards, changes, or interpretations that will come into force in future financial years to have a significant impact on the entity in the current or future financial years, nor on foreseeable future transactions.

Segment Reporting

Teleste reports its key financial figures starting from January 1, 2024, according to the new segment structure. The operational segments are Broadband Networks and Public Safety and Mobility. The group's reportable segments correspond to the group's operational segments. The group's shared functions are treated outside of segment reporting.

These presented segments are based on the group's internal organizational structure and internal financial reporting.

BUSINESS SEGMENTS

The Broadband Networks segment focuses on subscriber network products for fixed telecommunications networks, with the most significant customer base consisting of telecommunications operators. Customers can also include companies integrating larger entities and resellers that utilize Teleste's products in their overall deliveries.

The unit's main market area is Europe, but growth is particularly sought in North America. The unit develops, designs, and manufactures a large portion of its products in-house. Its R&D units operate in Finland and Belgium, and own production mainly takes place in Finland. The product range also includes products developed by third parties that complement Teleste's offerings.

The most significant customer base for the Public Safety and Mobility segment consists of train manufacturers and public sector organizations, such as public transport operators and authorities. The customer base also includes companies and integrators integrating larger entities that utilize Teleste's solutions in their overall deliveries.

The unit's main market area is Europe, but it also operates in North America and the Middle East. The unit designs, develops, and manufactures a large portion of its products in-house. Its R&D units operate in Finland and Poland, with own production mainly taking place in Finland. The product portfolio also includes products developed by third parties that complement Teleste's offerings.

ITEMS NOT ALLOCATED TO SEGMENTS

Items not allocated to segments include items related to group management, items treated as adjustments, and post-operating profit items of the group.

SEGMENT REPORTING

Since the sales between segments are minimal, the reported figures of the segments are the group's external figures from which internal transactions are eliminated.

The Board uses the adjusted operating result to evaluate the results of the reportable segments. The assets and liabilities of the segments are not reported separately.

Teleste Corporation has begun reporting two separate segments as of January 1, 2024. The reportable segments have been defined as Broadband Networks and Public Safety and Mobility business areas. The reportable segments will also constitute cash-generating units from the beginning of 2024.

Group has received grants of 0.4 million euros in Finland for development costs in year 2025 (0.4 million euros in year 2024). Of these grants, 0.0 million euros (0.0 million euros in year 2024) has been booked as deduction of activated development costs. Development grants have clause which states that may be retracted if the conditions on which the grants have been permitted, have changed.

For the purposes of impairment testing goodwill items of the Group have been allocated to the segments, each of which represents a separate cash-generating unit. The aggregate goodwill amount totalled 30.1 million euro at 31 December 2025 (30.1 million euro at 31 December 2024). Goodwill has been allocated to the following cash-generating unit:

million euros
Broadband Networks 16.8
Public Safety and Mobility 13.3

In goodwill impairment testing, the recoverable amount of cash-generating units is defined based on the value in use. The cash flow forecasts used in the testing are based on the strategies and business plans approved by the management. The calculations have been prepared for 5 years.

KEY ASSUMPTIONS

Forecasted Revenue Growth

The cash flow forecast for the first year is based on the 2026 budget according to the business plan. From 2027 onwards, cash flows are based on the long-term financial plan consistent with the strategy for the years 2027 and 2028. The revenue growth forecast for 2029 and 2030 is based on a conservative management estimate.

The average revenue growth used in the calculations is 22.7% for Broadband Networks and 7% for Public Safety and Mobility. Management's views on cash flows and growth estimates contain uncertainties as industry changes are difficult to predict.

Terminal Growth

The terminal value of the cash-generating unit in impairment calculations has been calculated with a terminal value growth rate of 1.5%.

Discount Rate

The discount rate used in the calculations is 8.8%.

The table below shows the recoverable amount of each cash-generating unit exceeding book value.

Impairment test
Meur 2025 2024
Broadband Networks 73.9 14.3
Public Safety and Mobility 26.0 20.2

The following tables show the key assumptions per unit and the percentage point change in the discount rate, resulting in the recoverable amount being equal to the carrying amount of the net assets of the cash-generating unit.

Revenue growth, change (percentage points)

LTI 2022 consists of three programs starting annually, with the following main elements: investing in Teleste shares as a prerequisite for participation, a fixed number of additional shares awarded after a three-year waiting period based on the above-mentioned share investment, and a performance-based share reward program with a three-year performance period. Additionally, as part of LTI 2022, a retention share reward program was established to be used for compensation in situations deemed necessary by the Board, for example, to retain key personnel, attract new key personnel, or other special situations decided by the Board.

The fixed matching share plan based on share investment includes the participant's investment in Teleste shares and the awarding of additional shares as a long-term share incentive reward. After a three-year waiting period, the key personnel will receive one additional share free of charge for every two shares invested.

The performance matching plan includes a three-year earning period. Any share rewards will be granted if the performance criteria set by the Board are achieved. The performance criteria applied to the performance-based share reward program in the programs starting in 2022, 2023, and 2024 are the total shareholder return (TSR) and the company's cumulative adjusted operating profit (EBIT). Participation in the program by individual key personnel requires the aforementioned investment in Teleste shares.

Under the 2022-2024 program, which ended in April 2025, the gross number of shares awarded was 14,663 shares and 0 performance-based additional shares. A total net amount of 14,264 shares was transferred to eligible key personnel in a directed share issue on March 31, 2025.

Under the 2023-2025 matching share plan, the gross amount of share rewards to be paid is a total of 21,660 shares, and for the performance-based share reward program a maximum of 292,656 shares. The Board approved 34 key personnel as eligible participants in the programs starting in 2023. At the end of 2025, a total of 27 key personnel have been approved as eligible participants in the program.

Under the 2024-2026 matching share plan, the gross amount of share rewards to be paid is a total of 24,850 shares, and for the performance-based share reward program a maximum of 438,921 shares. The Board approved 38 key personnel as eligible participants in the programs starting in 2024. At the end of 2025, a total of 34 key personnel have been approved as eligible participants in the program.

The company's management approved 45 key personnel as eligible to participate in the 2024-2026 retention program.

On June 25, 2025, Teleste Corporation transferred a total of 38,532 own shares held by the company free of charge in a directed share issue to key personnel under the 2024-2026 retention share reward program.

At the end of 2025, a total of 1 key personnel have been approved as eligible participants in the program. The remaining gross number of share rewards to be paid under the 2024-2026 retention program is 10,000 shares.

Share-Based Incentive Programme 2025

On February 10, 2025, Teleste's Board of Directors decided to establish a new long-term share-based incentive programme ("LTI 2025") to be offered to the company's key personnel.

The aim of the LTI 2025 program is to align the objectives and interests of key personnel with those of Teleste's shareholders through long-term share ownership, thereby increasing the company's value over the long term and promoting a performance-driven culture at Teleste. The intention is also to commit key personnel to the company and provide them with competitive, performance-based compensation.

LTI 2025 consists of three annually commencing programs with the following main elements: investing in Teleste shares as a prerequisite for participation, a fixed number of additional shares granted after a three-year waiting period based on the aforementioned share investment, and a performance-based share reward program with a three-year performance period. In addition, as part of LTI 2025, a retention share reward program was established, intended to be used in situations deemed necessary by the Board of Directors and the CEO, such as retaining key personnel, attracting new key personnel, or other special circumstances.

The matching share plan based on share investment includes the participant's investment in Teleste shares and the granting of additional shares as long-term share incentive compensation in return for the share investment. After a three-year waiting period, key personnel receive an additional share free of charge for each share they have invested.

The performance matching plan includes a three-year earning period. Possible share rewards will be granted if the performance criteria set by the Board of Directors are met. The performance criteria applied to the performance-based share reward program in the programs commencing in 2025, 2026, and 2027 are the total shareholder return (TSR) and the company's cumulative earnings per share (EPS). Participation in the program by an individual key personnel requires the aforementioned investment in Teleste shares.

The total gross number of share rewards to be paid under the matching share plan for 2025-2027 is 92,169 shares, and under the performance-based share reward program is up to 657,756 shares. The Board of Directors approved 38 key personnel as eligible to participate in the programs commencing in 2025. At the end of 2025, a total of 36 key personnel have been approved as eligible to participate in the program.

The company's management approved 2 key personnel as eligible to participate in the retention program commencing in 2025-2027. At the end of 2025, a total of 1 key personnel have been approved as eligible to participate in the program. The gross number of share rewards to be paid under the retention program for 2025-2027 is 30,000 shares.

Shares and shareholders

in 2022 and 2025. Under these programs, three-year earning periods starting annually have been launched. The share-based incentive programs valid during the 2025 financial year covered the earning periods 2023-2025, 2024-2026, and 2025-2027.

Each earning period requires an investment in Teleste shares for the duration of the three-year earning period.

In the LTI 2022 program, after the earning period, a key employee will receive one (1) additional share free of charge for every two (2) shares invested in the program. In addition, the programs offer the opportunity to earn performance-based additional shares as a reward based on the total shareholder return (TSR) of Teleste's share and the company's operating profit during the program period.

In the LTI 2025 program, after the earning period, a key employee will receive one (1) additional share free of charge for each share invested in the program. In addition, the programs offer the opportunity to earn performance-based additional shares as a reward based on the total shareholder return (TSR) of Teleste's share and the company's cumulative earnings per share (EPS) during the program period.

A potential share-based reward is paid at the end of the program, partly in shares and partly in cash.

The cash portion of the reward is intended to cover the taxes and tax-like payments arising from the reward for the individual.

Continued employment throughout the program period is a prerequisite for receiving the reward.

If the employment ends during the program, the individual will generally lose the right to the reward.

During the financial year, fixed additional shares earned under the 2022-2024 program and shares according to the commitment program were paid.

No performance-based shares were earned under the 2022-2024 earning period.

The main terms and conditions of the programs are presented in the table below.

Warranty provisions

The Group provides an average 30-month warranty for certain products. If defects are detected during the warranty period, products will be repaired at the Group's expense, or the customer will be given a corresponding new product. The amount of the warranty provision is based on past experience with defective products and an estimate of related expenses.

Other provisions

Other provisions include provisions for project revenue losses, pension provisions, and other provisions of minor value.

21. INCOME TAX PAYABLE FOR THE PERIOD

At the end of the accounting year, a tax receivable of EUR 1 174 thousand and a tax liability of EUR 72 thousand were recorded in respect of the income of the accounting year (as of December 31, 2024, the tax receivable was EUR 1 019 thousand and the tax liability was EUR 139 thousand).

22. FAIR VALUES OF FINANCIAL ASSETS AND LIABILITIES

Derivative instruments

Teleste uses currency forward contracts to hedge against transaction risks in foreign currencies.

The company applies hedge accounting to USD-denominated forecasted purchases. Changes in the fair values of instruments used for USD hedges are recorded through other comprehensive income. More information is provided in the Financial Risk Descriptions section of the notes. At the closing date, the fair value of currency hedges subject to hedge accounting was approximately EUR 38 thousand (EUR -54 thousand), consisting entirely of the time value of derivatives.

Changes in the fair values of other currency forward contracts used for hedging purposes are fully recognized in the income statement. The fair value of these currency forwards was EUR 19 thousand in 2025 (EUR 29 thousand) and has been recorded in financial items. Teleste's currency forwards are all Level 2.

Equity instruments and shares, measured at fair value through other comprehensive income

Equity instruments and shares, measured at fair value through other comprehensive income, consist of shares in unlisted companies and are classified as Level 3. The company's balance sheet includes insignificant investments in unlisted shares, which are valued at cost or at a lower value based on management's estimated fair value. The fair value of these investments has not been reliably determinable, and the estimate varies significantly, or the probabilities of different estimates within a range cannot be reasonably determined, making it difficult to use the fair value for measurement.

Trade payables and other liabilities or receivables

For trade payables and other receivables, except those based on derivative instruments, equals their fair value as the discounting is not significant, considering the short maturity of these items.

Financial Risk Management

The objective of the Group's financial risk management is to identify, evaluate and hedge financial risks to reduce the impacts of price fluctuations in financial markets and of other factors on earnings, balance sheet and cash flows as well as to guarantee cost-efficient funding for the Group at all times.

The Board has approved financial risk management guidelines and the allocation of responsibilities defined in the Group risk management policy and related operating policies

covering specific areas. The Board oversees the Group's risk management framework. The Group's administration is responsible for the coordination and control of the Group's total financial risk position and external hedging transactions with banks in the name of the parent company. Teleste is risk averse in its treasury activities. The identification of the exposure is a common task of the business units and the Group administration.

MARKET RISK

Market risk includes three types of risk: currency risk, price risk and fair value interest rate risk. Fluctuations of foreign exchange rates, market prices or market interest rates may cause a change in the value of a financial instrument. These changes may have an effect on the consolidated earnings, balance sheet and cash flows.

CURRENCY RISK

TRANSACTION RISK

Foreign exchange exposures of the Group's units arise from receivables and accounts payables denominated in foreign currency, sales and purchase contracts and from forecast sales and purchases. Major part of the Group's sales is in Euro. The most significant non-euro sales currencies are US dollar (19 per cent), UK pound sterling (6 per cent), PLN (8 per cent), and Swedish and Norwegian crowns (3 per cent). Significant part of expenses, 55 per cent, arise in Euro, in US dollar 36 per cent and in CNY 8 per cent. The hedging decisions are based on the expected net cash flow for the following six months.

In principle Teleste hedges forecast and probable cash flows. The Group uses forward exchange contracts and forward options.

According to the Group's currency risk management policy all material currency risks are hedged at least six months ahead and the Group's transaction position shall at all times be hedged 70-100 % by currency. The level of hedges is monitored on a monthly basis.

At the year-end 2025 the fair value of currency derivatives amounted to 13.5 million euro (31. Dec 2024: 10.7 million euro).

The Group has decided to apply hedge accounting to derivatives in USD-denominated purchases. The objective of hedge accounting is to eliminate the effect of changes in USD exchange rates on the Group's purchases in accordance with the Group's Currency and Interest rate Risk Policy.

The hedging is considered a cash flow hedge and the hedge covers the share of USD purchases made in accordance with the

Group's policy, the so called layered approach.

In hedging relationships, only the spot portion of forward contracts is defined as a hedging instrument. The spot portion is determined based on the relevant spot market rates. The difference between the contractual forward rate and the spot market rate is defined as forward points. It is discounted if it is material.

Changes in the interest rate portion of the forward exchange contracts and the time value of options related to the hedged item are recorded in the hedging expense reserve.

No items related to forward exchange contracts and options were transferred from the cash flow hedge fund to profit or loss during the financial year.

The effectiveness of the hedge is determined at the inception of the hedging relationship. Forward-looking performance evaluations are performed on a regular basis to ensure that there is an economic relationship between the hedged item and the hedging instrument. Credit risk has no material effect on the value of the hedging instrument. The hedged item and the hedging instruments have the same nominal value. A change in the USD exchange rate has the same but opposite effect on the value, so the hedging ratio is always 1:1.

Inefficiency may arise if the timing or amount of the anticipated purchase changes materially.

Hedge accounting has significantly reduced the impact of USD exchange rate fluctuations on the company's 2024 and 2025 financial year results.

Currency risk is also managed through, among others, operational planning, pricing and offer terms. Reprising interval varies between 3 and 24 months.

TRANSLATION RISK

Since the Group's currency risk exposure regarding net investments in foreign operations is relatively low, the equity position, i.e. differences in the calculatory euro values of these amounts (translation risk) is not actively hedged. At 31 December 2025 the total non-euro-denominated equity of the Group's foreign subsidiaries amounted to 4.2 million euro (31 Dec. 2024: 5.5 million euro).

INTEREST RATE RISK

Teleste's interest rate risk mainly comprises cash flow interest rate risk that arises from the interest-bearing liabilities. The Group can have floating or fixed interest loans and use interest swap contracts to achieve financial objectives. At the end of the reporting period 24.5 (30.2) million euros have short-term interest as a reference rate with the interest period less than one year. At the end of 2025, the loans have been hedged with an interest rate swap agreement up to EUR 20.5 (8.8) million euros.

The company has two interest rate swap agreements, of which one is subject to hedge accounting.

All Group loans are denominated in Euro. In 2025, the average interest rate of the loan portfolio was 4.54 per cent. All right-of-use agreements are fixed-rate. The Group does not hedge the risk position resulting from the fair value interest rate risk as the position is small. The average balances of the variable rate loans realized during the period have been used in calculating the sensitivity analysis required by IFRS 7. At the closing date 31 December 2025, the effect on variable rate interest-bearing liabilities on profit before taxes would have been +- 245 thousand euro had the interest rate increased or decreased by 1 percentage point.

CREDIT RISK

The Group's accounts receivables are dispersed to a number of customers worldwide. Thus the primary responsibility for commercial credit risks lies with the Group's geographical areas. Commercial credit risks are managed in accordance with the Group's credit policy and are reduced for example with collaterals. Some accounts receivables are covered by a credit insurance. Credit risks are approved and monitored by the Group management team.

The credit risk related to financial instruments, i.e. counterparty risk is managed in the Group administration. Counterparty risk realises if a counterparty is unable to meet its obligations. In order to minimise counterparty risks, Teleste seeks to limit the counterparties, such as banks and other financial institutions, to those which have good credit rating. Liquid funds are invested in liquid instruments with low credit risk, e.g. in short-term bank deposits and commercial papers.

All receivables are without collaterals. There are no significant concentrations of risk with respect to the receivables of the Group.

LIQUIDITY RISK

Liquidity risk is monitored through Group's cash flow forecasts. The Group seeks to reduce liquidity risk through sufficient cash reserves and credit facility arrangements as well as with balanced maturity profile of loans. Efficient cash and liquidity management also reduces liquidity risk. At the year-end 2025 the Group's cash reserves totaled 9.1 (8.8) million euros and its interest-bearing net debt 28.7 (34.2) million euros. The Group administration raises the Group's interest-bearing

debt centrally. At 31 December 2025 Teleste had committed and available credit facilities as well as other agreed and undrawn loans amounting to 16.0 (14.0) million euros.

During the third quarter in 2024, the company entered into a syndicated refinancing arrangement consisting of a term loan, credit limits and a non-binding guarantee limit. Teleste Corporation has credit limits and credit agreements with a total value of EUR 53.0 (53.0) million. All financing agreements include financial covenants regarding the leverage ratio, net debt and adjusted EBITDA, as well as a minimum liquidity level. The financing agreements are secured by corporate mortgages totaling EUR 68.9 million, pledges of subsidiary shares totaling EUR 32.0 million and pledges of internal bonds totaling EUR 39.3 million. The financing agreement includes a conditional two one-year extension option. During the third quarter of 2025, the company agreed to utilise the first option.

Teleste Corporation is the parent company of the Teleste Group. Business ID of Teleste Corporation is 1102267-8 with registered office in Turku. The company registered address is Telestenkatu 1 20660 Littoinen.

COMPARABILITY

During the 2024 financial year, the company completed two intra group business transfers through which its operational business—including properties, production, and most personnel—was transferred to subsidiaries of the group.

FOREIGN CURRENCY TRANSACTIONS

Transactions in foreign currencies are recorded at the rates of exchange prevailing on the date of the transaction. At the end of the accounting period, unsettled foreign currency balances are translated into the accounting currency at the closing rate on the balance sheet date. Foreign exchange gains and losses on trade accounts receivable and payable are adjusted to revenues and operating expenses, respectively. Other foreign exchange gains and losses are recorded as financial income and expenses.

DERIVATIVES

The company has currency forward exchange agreements. Exchange agreements are designed to eliminate the effect of currency exposures on the company performance and financial standing. The interest swap agreements are taken for specicig long term floating interest loans to eliminate the interest risk.

Derivative contracts are presented in accordance with AA 5:2§, so that the negative fair values of the hedges outside the IFRS hedge calculation are recorded as an expense and as a mandatory provision. The hedges within the scope of hedge accounting are presented as off-balance sheet liabilities in the notes. More extensive notes are presented in the Group consolidated financial statement.

Company's corporate hedging policy is to cover all material currency risks at least six months ahead. The effect on company performance of the exchange rate agreements is recorded on their exercise day.

VALUATION OF FIXED ASSETS

The balance sheet values for fixed assets are stated as historical cost, less the accumulated depreciation and amortisation. Depreciation and amortisation is calculated on straight-line basis over the expected useful lives of the assets. Estimated useful lives for various assets are:

Intangible assets 3 years
Goodwill 8 years
Other capitalised expenditure 3 years
Buildings 25 to 33 years

Machinery 3 to 5 years
Computers 0 to 3 years

Write-downs on permanent impairment of the assets are recorded when it becomes evident that the carrying amount is not recoverable. Companies acquired or established during the financial period are included in the subsidiary shares as of date of acquisition or formation. Companies disposed of in the financial period have been included in the subsidiary shares up to the date of disposal. Long-term investments and receivables include financial assets, which are intended to be held for over one year.

LEASED ASSETS

Purchases made under operating leases and capital leases are entered into income statement as renting expenses.

CASH

Cash and cash equivalents include cash in hand and in bank.

REVENUE RECOGNITION

Revenue is adjusted for discounts, indirect taxes associated with sales, and exchange differences from the conversion of foreign-currency trade receivables. Revenue is recognized when the service or product is delivered.

From the beginning of the 2025 financial year, the company has reported administrative service charges as part of revenue (previously included in other operating income). Due to the 2024 business transfers, the company's operations primarily consist of administrative functions.

RESEARCH AND DEVELOPMENT

R&D expenses are recorded as revenue expenditure.

RECOGNITION OF GRANTS RECEIVED

Grants received are recognized as other operating income to the extent that the related project generates eligible costs in accordance with the grant decision and terms. The company also considers any required self-financing share. Grant-related repayment liabilities are disclosed in the notes under contingent liabilities.

PENSION ARRANGEMENTS

The statutory pension liabilities of Finnish companies are funded through pension insurance.

Auditor's Report

To the Annual General Meeting of Teleste Oyj

REPORT ON THE AUDIT OF THE FINANCIAL STATEMENTS

OPINION

In our opinion

  • the consolidated financial statements give a true and fair view of the group's financial position, financial performance and cash flows in accordance with IFRS Accounting Standards as adopted by the EU
  • the financial statements give a true and fair view of the parent company's financial performance and financial position in accordance with the laws and regulations governing the preparation of financial statements in Finland and comply with statutory requirements.

Our opinion is consistent with the additional report to the Audit Committee.

What we have audited

We have audited the financial statements of Teleste Oyj (business identity code 1102267-8) for the year ended 31 December 2025. The financial statements comprise:

  • the consolidated balance sheet, statement of comprehensive income, statement of changes in equity, statement of cash flows and notes, which include material accounting policy information and other explanatory information
  • the parent company's balance sheet, income statement, cash flow statement and notes.

BASIS FOR OPINION

We conducted our audit in accordance with good auditing practice in Finland. Our responsibilities under good auditing practice are further described in the Auditor's Responsibilities for the Audit of the Financial Statements section of our report.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Independence

We are independent of the parent company and of the group companies in accordance with the ethical requirements that are applicable in Finland and are relevant to our audit, and we have fulfilled our other ethical responsibilities in accordance with these requirements.

To the best of our knowledge and belief, the non-audit services that we have provided to the parent company and group companies are in accordance with the applicable law and regulations in Finland and we have not provided non-audit services that are prohibited under Article 5(1) of Regulation (EU) No 537/2014. The non-audit services that we have provided are disclosed in note 5 to the Financial Statements.

OUR AUDIT APPROACH

Overview

Materiality
  • Overall group materiality: EUR 1 380 000, which represents approximately 1% of net sales
Audit Scope
  • Our audit procedures covered all countries and group locations significant to the Group, with emphasis on the most prominent locations in Finland and USA.
Key Audit matters
  • Valuation of goodwill
  • Valuation of inventory
  • Capitalization of R&D costs

As part of designing our audit, we determined materiality and assessed the risks of material misstatement in the financial statements. In particular, we considered where management made subjective judgements; for example, in respect of significant accounting estimates that involved making assumptions and considering future events that are inherently uncertain.

Materiality

The scope of our audit was influenced by our application of materiality. An audit is designed to obtain reasonable assurance whether the financial statements are free from material misstatement. Misstatements may arise due to fraud or error. They are considered material if individually or in aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of the financial statements.

Based on our professional judgement, we determined certain quantitative thresholds for materiality, including the overall group materiality for the consolidated financial statements as set out in the table below. These, together with qualitative considerations, helped us to determine the scope of our audit and the nature, timing and extent of our audit procedures and to evaluate the effect of misstatements on the financial statements as a whole.


Financial statements 2025

Report of the Board of Directors

Group

Parent company

Shares and shareholders

Overall group materiality EUR 1,380,000 (previous year EUR 1,300,000)
How we determined it Approximately 1 % of net sales
Rationale for the materiality benchmark applied The group’s profitability has been volatile during the last years due to revised strategy, strategy related divestments and investments in product development. Therefore, we chose revenue as the benchmark because, in our view, it is the benchmark against which the performance of the Group is commonly measured by users and is a generally accepted benchmark. We chose 1.0% which is within the range of acceptable quantitative materiality thresholds in auditing standards.

How we tailored our group audit scope

We tailored the scope of our audit, taking into account the structure of the Teleste Group, the accounting processes and controls, and the industry in which the group operates.

Our audit procedures covered all significant components of the group. The audit of the consolidated financial statements was focused on the most significant locations in Finland, where we performed an audit based on the size of the companies and the characteristics of the risks. Additionally, we performed audit of one or more financial statement line items in USA. In other group companies we have performed analytical audit procedures to mitigate the risk of material misstatements in the consolidated financial statements.

Key Audit Matters

Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the financial statements of the current period. These matters were addressed in the context of our audit of the financial statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters.

As in all of our audits, we also addressed the risk of management override of internal controls, including among other matters consideration of whether there was evidence of bias that represented a risk of material misstatement due to fraud.

| KEY AUDIT MATTER IN
THE AUDIT OF THE GROUP | HOW OUR AUDIT ADDRESSED
THE KEY AUDIT MATTER |
| --- | --- |
| VALUATION OF GOODWILL | |
| Refer to accounting principles for the consolidated financial statements and to note 10 in the consolidated financial statements.

Goodwill is one of the most significant balance sheet items and amounted to EUR 30,1 million at the balance sheet date. The determination and whether an impairment charge is required involves significant management judgement, including identifying on which cash generating unit level the goodwill is tested and estimating the future performance of the business and the discount rate applied to these future cash flows.

Due to materiality and judgment associated we have considered valuation of goodwill as key audit matter in the audit of the Group. | Our audit focused on assessing the appropriateness of management’s judgment and estimates used in the goodwill impairment analysis through the following procedures:

We tested the methodology applied in the value in use calculation by comparing it to the requirements of IAS 36, Impairment of Assets, and we tested the mathematical accuracy of calculation.

We evaluated the process by which the future cash flow forecasts are drawn up, including comparing them to the latest Board approved targets and long-term plans.

We tested the key underlying assumptions for the cash flow forecasts, including sales and profitability forecasts, discount rate used and the implied growth rates beyond the forecasted period.

We compared the current year actual results included in the prior year impairment model to consider whether forecasts included assumptions that, with hindsight, had been optimistic.

We tested whether the sensitivity analysis performed by the management around key assumptions of the cash flow forecast are appropriate by considering the likelihood of the movements of these key assumptions. |

KEY AUDIT MATTER IN THE AUDIT OF THE GROUP HOW OUR AUDIT ADDRESSED THE KEY AUDIT MATTER
VALUATION OF INVENTORY
Refer to accounting principles for the consolidated financial statements and to note 14 in the consolidated financial statements. Inventory is one of the most significant balance sheet items and amounted to EUR 26,9 million at the balance sheet date. Inventories are valued at the lower of cost or net realisable value. Costs are measured with FIFO method. Net realisable value is the estimated selling price in the ordinary course of business, less sales cost and costs needed to finish the production of the goods. The cost of inventories includes all direct costs incurred in acquiring the inventories and bringing them to their existing location and condition. In the case of manufactured inventories and work in progress, costs include share of overheads based on normal operating capacity. Impairment due to obsolescence is considered when assessing the valuation of inventories. Obsolescence provision is based on the best estimate at the balance sheet date and required judgement from management. Valuation of inventory is a key audit matter due to the size of the balance and because inventory valuation includes management judgement. We assessed the compliance of the groups accounting policies in comparison to IAS 2 – Inventories and performed control testing and test of details to valuation and existence of the inventories. We tested a sample of inventory items to third party purchase invoices. We also tested management’s calculations on the absorption of relative share of indirect production overheads. We attended stock takings in selected inventory locations to obtain audit evidence regarding existence and condition of the inventory. During the stock takes we assessed the appropriateness of the stock takes and performed independent test counts. We compared the value of selected finished goods inventory items to the sales prices. We assessed the principles related to the determination of the obsolescence provision and the adequacy of the obsolescence provisions recorded.
KEY AUDIT MATTER IN THE AUDIT OF THE GROUP HOW OUR AUDIT ADDRESSED THE KEY AUDIT MATTER
--- ---
CAPITALIZATION OF R&D COSTS
Refer to accounting principles for the consolidated financial statements and to note 10 in the consolidated financial statements. Groups’s capitalized development amounted to EUR 11,2 million in the financial statements. Capitalization of R&D costs requires use of judgment as capitalization requires estimating technical and economic feasibility of the product developed. In addition, there is judgement involved in assessing recoverability of capitalized R&D costs as future cash flows generated by these intangible assets needs to be estimated. Due to materiality and judgment associated with capitalization of R&D costs, we have considered capitalization of R&D as key audit matter in the audit of the Group. We assessed appropriateness of the company’s R&D capitalization policy in comparison to IAS 3B – Intangible Assets. We evaluated the design and appropriateness of the process relating to R&D capitalization. We assessed whether capitalization criteria for R&D projects are met. We tested a sample of invoices and personnel related costs capitalized during the year. We evaluated the relevant assumptions used in the impairment testing of intangible assets, focusing on the reasonableness of the forecasted economic information.
We have no key audit matters to report with respect to our audit of the parent company financial statements.
There are no significant risks of material misstatement referred to in Article 10(2c) of Regulation (EU) No 537/2014 with respect to the consolidated financial statements or the parent company financial statements.

Responsibilities of the Board of Directors and the Managing Director for the Financial Statements

The Board of Directors and the Managing Director are responsible for the preparation of consolidated financial statements that give a true and fair view in accordance with IFRS Accounting Standards as adopted by the EU, and of financial statements that give a true and fair view in accordance with the laws and regulations governing the preparation of financial statements in Finland and comply with statutory requirements. The Board of Directors and the Managing Director are also responsible for such internal control as they determine is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the financial statements, the Board of Directors and the Managing Director are responsible for assessing the parent company's and the group's ability to continue as a going concern, disclosing, as applicable, matters relating to going concern and using the going concern basis of accounting. The financial statements are prepared using the going concern basis of accounting unless there is an intention to liquidate the parent company or the group or to cease operations, or there is no realistic alternative but to do so.

Auditor's Responsibilities for the Audit of the Financial Statements

Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor's report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with good auditing practice will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements.

As part of an audit in accordance with good auditing practice, we exercise professional judgment and maintain professional skepticism throughout the audit. We also:

  • Identify and assess the risks of material misstatement of the financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.
  • Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the parent company's or the group's internal control.
  • Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by management.
  • Conclude on the appropriateness of the Board of Directors' and the Managing Director's use of the going concern basis of accounting and based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the parent company's or the group's ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor's report to the related disclosures in the financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor's report. However, future events or conditions may cause the parent company or the group to cease to continue as a going concern.
  • Evaluate the overall presentation, structure and content of the financial statements, including the disclosures, and whether the financial statements represent the underlying transactions and events so that the financial statements give a true and fair view.
  • Plan and perform the group audit to obtain sufficient appropriate audit evidence regarding the financial information of the entities or business units within the group as a basis for forming an opinion on the group financial statements. We are responsible for the direction, supervision and review of the audit work performed for purposes of the group audit. We remain solely responsible for our audit opinion.

We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit.

We also provide those charged with governance with a statement that we have complied with relevant ethical requirements regarding independence, and communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, related safeguards.

From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of the financial statements of the current period and are therefore the key audit matters. We describe these matters in our auditor's report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.

Our responsibility is to, in accordance with Chapter 7, Section 8 of the Securities Markets Act, provide assurance on the financial statements that have been prepared in accordance with the Commission's regulatory technical standard. We express an opinion on whether the consolidated financial statements that are included in the ESEF financial statements have been tagged, in all material respects, in accordance with the requirements of Article 4 of the Commission's regulatory technical standard.

Our responsibility is to indicate in our opinion to what extent the assurance has been provided. We conducted a reasonable assurance engagement in accordance with International Standard on Assurance Engagements (ISAE) 3000 (Revised).

The engagement includes procedures to obtain evidence on:

  • whether the primary financial statements in the consolidated financial statements that are included in the ESEF financial statements have been tagged, in all material respects, with iXBRL tags in accordance with the requirements of Article 4 of the Commission's regulatory technical standard and
  • whether the notes and company's identification data in the consolidated financial statements that are included in the ESEF financial statements have been tagged, in all material respects, with iXBRL tags in accordance with the requirements of Article 4 of the Commission's regulatory technical standard and
  • whether there is consistency between the ESEF financial statements and the audited financial statements.

The nature, timing and extent of the selected procedures depend on the auditor's judgment. This includes an assessment of the risk of a material deviation due to fraud or error from the requirements of the Commission's regulatory technical standard.

We believe that the evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

OPINION

Our opinion pursuant to Chapter 7, Section 8 of the Securities Markets Act is that the primary financial statements, notes and company's identification data in the consolidated financial statements that are included in the ESEF financial statements of Teleste 743700CJRQRU0007GN59-2025-12-31-0-fi.zip for the financial year 1.1.-31.12.2025 have been tagged, in all material respects, in accordance with the requirements of the Commission's regulatory technical standard.

Assurance Report on the Sustainability Report

To the Annual General Meeting of Teleste Oyj

We have performed a limited assurance engagement on the group sustainability report of Teleste Oyj (business identity code 1102267-8) that is referred to in Chapter 7 of the Accounting Act and that is included in the report of the Board of Directors for the reporting period 1.1. – 31.12.2025.

OPINION

Based on the procedures we have performed and the evidence we have obtained, nothing has come to our attention that causes us to believe that the group sustainability report does not comply, in all material respects, with

  1. the requirements laid down in Chapter 7 of the Accounting Act and the sustainability reporting standards (ESRS), and
  2. the requirements laid down in Article 8 of the Regulation (EU) 2020/852 of the European Parliament and of the Council on the establishment of a framework to facilitate sustainable investment, and amending Regulation (EU) 2019/2088 (EU Taxonomy).

Point 1 above also contains the process in which Teleste Oyj has identified the information for reporting in accordance with the sustainability reporting standards (double materiality assessment).

Our opinion does not cover the tagging of the group sustainability report with digital XBRL sustainability tags in accordance with Chapter 7, Section 22, Subsection 1(2), of the Accounting Act, because sustainability reporting companies have not had the possibility to comply with that requirement in the absence of requirements for the tagging of sustainability information in the ESEF regulation or other European Union legislation.

BASIS FOR OPINION

We performed the assurance of the group sustainability report as a limited assurance engagement in compliance with good assurance practice in Finland and with the International Standard on Assurance Engagements (ISAE) 3000 (Revised) Assurance Engagements Other than Audits or Reviews of Historical Financial Information.

Our responsibilities under this standard are further described in the Responsibilities of the Authorized Group Sustainability Auditor section of our report.

We believe that the evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

AUTHORIZED GROUP SUSTAINABILITY AUDITOR'S INDEPENDENCE AND QUALITY MANAGEMENT

We are independent of the parent company and of the group companies in accordance with the ethical requirements that are applicable in Finland and are relevant to our engagement, and we have fulfilled our other ethical responsibilities in accordance with these requirements.

The authorized group sustainability auditor applies International Standard on Quality Management ISQM 1, which requires the authorized sustainability audit firm to design, implement and operate a system of quality management including policies or procedures regarding compliance with ethical requirements, professional standards and applicable legal and regulatory requirements.

RESPONSIBILITIES OF THE BOARD OF DIRECTORS AND THE MANAGING DIRECTOR

The Board of Directors and the Managing Director of Teleste Oyj are responsible for:

  • the group sustainability report and for its preparation and presentation in accordance with the provisions of Chapter 7 of the Accounting Act, including the process that has been defined in the sustainability reporting standards and in which the information for reporting in accordance with the sustainability reporting standards has been identified,
  • the compliance of the group sustainability report with the requirements laid down in Article 8 of the Regulation (EU) 2020/852 of the European Parliament and of the Council on the establishment of a framework to facilitate sustainable investment, and amending Regulation (EU) 2019/2088, and for
  • such internal control as the Board of Directors and the Managing Director determine is necessary to enable the preparation of a group sustainability report that is free from material misstatement, whether due to fraud or error.

INHERENT LIMITATIONS IN THE PREPARATION OF A SUSTAINABILITY REPORT

Preparing the consolidated sustainability report requires the company to perform a materiality assessment to identify the relevant reportable matters. This process involves significant management judgement and choices. Sustainability reporting is also inherently characterised using estimates and assumptions as well as measurement and evaluation uncertainties.

In particular, the determination of greenhouse gas emissions involves inherent uncertainty, as the scientific information used to establish emission factors and to combine emissions from different gases is incomplete.

In addition, when reporting forward looking information in accordance with the ESRS standards, management is required to make assumptions about possible future events, disclose any planned actions related to such events, and prepare the forward looking information based on those assumptions. The actual outcomes will likely differ, as forecasted events often do not unfold as expected.

RESPONSIBILITIES OF THE AUTHORIZED GROUP SUSTAINABILITY AUDITOR

Our responsibility is to perform an assurance engagement to obtain limited assurance about whether the group sustainability report is free from material misstatement, whether due to fraud or error, and to issue a limited assurance report that includes our opinion. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the decisions of users taken on the basis of the group sustainability report.

Compliance with the International Standard on Assurance Engagements (ISAE) 3000

(Revised) requires that we exercise professional judgment and maintain professional skepticism throughout the engagement. We also:

  • Identify and assess the risks of material misstatement of the group sustainability report, whether due to fraud or error, and obtain an understanding of internal control relevant to the engagement in order to design assurance procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the parent company's or the group's internal control.
  • Design and perform assurance procedures responsive to those risks to obtain evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.

DESCRIPTION OF THE PROCEDURES THAT HAVE BEEN PERFORMED

The procedures performed in a limited assurance engagement vary in nature and timing from, and are less in extent than for, a reasonable assurance engagement. The nature, timing and extent of assurance procedures selected depend on professional judgment, including the assessment of risks of material misstatement, whether due to fraud or error. Consequently, the level of assurance obtained in a limited assurance engagement is substantially lower than the assurance that would have been obtained had a reasonable assurance engagement been performed.

Our procedures included for ex. the following:

  • We interviewed the company's management and the persons responsible at group level for collecting and reporting the information included in the consolidated sustainability report, in order to obtain an understanding of the key processes, controls and information systems related to the collection and consolidation of sustainability data.
  • We reviewed the company's internal guidelines and policies relevant to the information presented in the consolidated sustainability report.
  • We reviewed, to the extent applicable, the background documentation and materials prepared by the company and assessed whether they support the information included in the consolidated sustainability report.
  • We conducted a site visit at a selected location.
  • We assessed whether the consolidated sustainability report, in all material respects, meets the ESRS requirements related to material sustainability matters.
  • Regarding EU Taxonomy disclosures, we obtained an understanding of the process by which the company has identified taxonomy eligible and taxonomy aligned economic activities, and we assessed the compliance of the related disclosures with the applicable regulations.
