Årsredovisning 2025
Year 2025 Stora Enso’s development in 2025 was characterised by financial improvement, strategic asset management, organisational transformation, and a continued focus on operational excellence. Despite market volatility and subdued demand, the Group’s proactive measures and structural changes strengthened its competitiveness and resilience in an evolving global environment. The operating environment remained exceptionally challenging in 2025. Market uncertainty was amplified by geopolitical tensions and supply chain disruptions, undermining consumer confidence and dampening demand across several business areas. Fluctuating demand, overcapacity, instability in the pulp market, and weakness in the construction sector exerted pressure on the entire industry. Wood prices continued to rise and remained high throughout the year, increasing cost pressures, particularly in Finland and Sweden. This situation reinforced the need to adjust operations, enhance efficiency, and safeguard long-term competitiveness. Despite the challenging market conditions, Stora Enso continued to strengthen profitability and secure cash flow. Net debt to EBITDA ratio improved to approximately 2.8x at the end of 2025, reflecting effective working capital management and targeted asset arrangements. The value creation programme also progressed as planned. By year-end, its cumulative impact on results was significant, providing a solid foundation for further improvements in profitability. Main strategic actions Throughout 2025, Stora Enso pursued systematic efforts across the Group to improve profitability, cash flow, and cost competitiveness through initiatives in sourcing, operational efficiency, commercial excellence, working capital management, and fixed cost optimisation. The new consumer board line at the Oulu site in Finland started operations in the beginning of 2025. The flexible converted line with an annual capacity of 750,000 tonnes produces folding box board (FBB) and coated unbleached kraft (CUK) for frozen, chilled and dry food, as well as beverage multi-packaging, primarily for customers in Europe and North America. The EUR 1 billion investment further strengthens the Group’s strategic focus on renewable packaging materials. The acquisition of the Finnish sawmill company Junnikkala Oy was finalised in May. It secures a cost-efficient wood supply to Stora Enso’s packaging board site in Oulu, and supports the Group’s wood products business with new production assets. In September, Stora Enso finalised the divestment of 12.4% of its Swedish forest holdings at an enterprise value of EUR 900 million, in line with the accounting fair value of the divested forest assets. In November, Stora Enso’s Board of Directors approved a plan to separate Stora Enso’s Swedish forest assets into a new publicly-listed company in 2027, creating Europe’s largest listed pure play forest company. Also in November, Stora Enso initiated a strategic review of its Central European sawmills and building solutions operations. The review covers seven sawmills in Austria, Czechia, Poland, and Lithuania, and further processing units with three cross-laminated-timber (CLT) mills. While the business holds a strong position in an attractive market, it does not create synergies for Stora Enso’s renewable packaging operations.

Demand in Europe remained stagnant. Macroeconomic and geopolitical uncertainties limited growth potential. The global cartonboard market remained oversupplied due to heavily increased capacity, especially in China. Global containerboard demand increased 2% in 2025. In Europe, conversions of former graphic paper mills to recycled testliner increased capacity and kept market oversupplied. European publication paper demand declined 9% in 2025, driven by structural demand erosion and macroeconomic uncertainty. As result of weaker demand, market remained oversupplied despite of some capacity closures. European corrugated packaging demand grew 2% in 2025, led by Central and Eastern Europe, especially Poland. E-commerce and retail sales supported growth, while stable inflation and low unemployment provided a favourable backdrop. However, overcapacity remains a challenge. Global demand for chemical market pulp increased 2.3% in 2025. Demand for hardwood pulp increased 3.2%, whereas growth in softwood pulp demand was modest at 0.7%. The global chemical market pulp capacity remained flat in 2025. Hardwood market pulp capacity increased by 1.6% as new capacity was ramping up in South America. Softwood capacity continued to decline by 2.1% due to capacity closures. Unbleached kraft pulp (UKP) capacity increased slightly by 0.9%. The overall shipment-to-capacity balance stood at 90%, nearly 2 percent points up from 2024. Global pulp inventories were considered balanced in 2025. Softwood pulp inventories have remained elevated throughout the year despite capacity curtailments. Hardwood pulp inventories were balanced most of the year thanks to capacity curtailments and grade conversions. Global softwood markets stabilised in 2025 after a weak 2024, with modest year-on-year demand growth of around 1–2% driven mainly by North America and early signs of recovery in Europe. Asia remained mixed, with China below previous peak levels but providing a stable baseline for global trade, while Oceania stayed steady at a small scale. Raw material availability (sawlogs) improved modestly in many regions as harvesting and forest access normalised, but supply tightness persists in selected markets (like Central Europe) and keeping pressure on input costs despite recovering demand.

Our year 2025 Our strategy Our people Governance Shareholders Report of the Board of Directors Sustainability Statement Financial Statements Appendices ≡ U n a u d i t e d 50 ===== SIDA 51 ===== Financial results – Group Group sales increased 3% year-on-year to EUR 9,326 (9,049) million, supported by higher deliveries in all segments, partially impacted by the Finnish political strike in 2024. The structural changes had a positive impact as the Junnikkala acquisition and the consumer board line ramp-up in Oulu increased sales. Adjusted EBIT was EUR 528 (598) million, and the adjusted EBIT margin was 5.7%. Adjusted EBIT decreased mainly due to the ramp-up of the Oulu consumer board line. Higher sales prices and lower fixed costs were offset by increased wood costs. Earnings per share was EUR 0.88 (-0.17) and earnings per share excluding fair valuations was EUR 0.41 (-0.56). The IFRS operating result was EUR 942 (93) million. The IFRS operating result includes a positive net effect of EUR 401 (positive 421) million from biological asset valuation from subsidiaries and joint operations. The positive impact comes mainly from the increase in fair valuation in Stora Enso owned forests in Sweden, mostly driven by increases in estimated long-term wood prices. There is also a positive net effect of EUR 89 (positive 52) million from Stora Enso’s share of net result of associated companies. The positive impact comes mainly from Finnish forests operational result, through Stora Enso’s 41% investment in Tornator. A storm in the end of December negatively affected a portion of the Swedish forest assets. Estimated damages of EUR 29 million were booked as reduction in biological assets, adversely impacting the IFRS result. The full extent of the damage and potential insurance compensation is still being assessed. Tangible and intangible asset (including goodwill) impairments amounted to EUR 26 (746) million. The items affecting comparability (IAC) had an adverse impact of EUR 19 (870) million on IFRS operating result. The main IACs in 2025 relate to the disposal of Swedish forest assets, restructuring costs related to various units and forest related damages. The IACs in 2024 mainly relate to the impairments in Packaging Materials, Packaging Solutions and Wood Products segments as well as restructuring related costs. Fair valuations and non-operational items (FV) had a positive net impact on the IFRS operating result of EUR 434 (364) million. The main IAC and FV items are presented in the chapter Alternative Performance Measures. Net financial expenses at EUR 159 (211) million were EUR 52 million lower than a year ago. Net interest expenses, at EUR 153 million, increased by EUR 27 million. The net interest expense increase was mainly due to a significant reduction in interest income from deposits and cash equivalents, driven by lower average interest rates and cash balances during the year. Although interest expenses on loans decreased due to lower average borrowings, the reduction did not fully offset the decline in interest income. Other net financial expenses, at EUR 26 million, were EUR 38 million lower, mainly due to reversal of EUR 25 million impairment related to the sale of Russia operations. The net foreign exchange impact in respect of cash equivalents, interest-bearing assets and liabilities and related foreign-currency hedges amounted to a gain of EUR 20 (loss of EUR 20) million, mainly due to revaluation of foreign currency net debt in subsidiaries located in China. The net tax totalled EUR -97 (-65) million, equivalent to an effective tax rate of 12.4% (-55.4%), as described in more detail in note 2.6 Income taxes. The loss attributable to non-controlling interests was EUR 9 (EUR 48) million, leaving a profit of EUR 695 (loss of EUR 136) million attributable to Company shareholders. Adjusted return on capital employed was 3.8% (4.3%). The Group capital employed was EUR 13,830 million on 31 December 2025, an increase of EUR 134 million, due to investment projects, mainly the consumer board investment at the Oulu site, increase of the fair valuation of forest and energy assets, acquisition of Junnikkala sawmills, partly offset by the disposal of part of the Swedish forests.

Cash flow from operations had a positive impact from a decrease in working capital of EUR 51 (283) million and cash flow after investing activities benefited from lower fixed assets outflows related to Oulu as compared to 2024. Payments related to previously recognised provisions were EUR 39 (100) million.

The decrease in net interest-bearing liabilities was mainly driven by the sale of the 12.4% share of the Group’s Swedish forest assets at the end of the third quarter. Cash and cash equivalents net of bank overdrafts decreased to EUR 1,206 (1,993) million. The net debt/equity ratio at 31 December 2025 decreased to 0.29 (0.37). The ratio of net debt to the last 12 months’ adjusted EBITDA decreased to 2.8 (3.0) due to lower net interest-bearing liabilities. The average interest rate on borrowings for the full year 2025 decreased to 3.8% (4.1%) with a run-rate of 4.0% as per the end of the fourth quarter.

Stora Enso had in total EUR 800 million committed undrawn credit facilities as per 31 December 2025. The changes in the fair value of forest land, net of deferred taxes, which are recognised in other comprehensive income (OCI) decreased the equity by EUR 307 million (decreased by EUR 223 million), mainly due to increase in the discount rate. The changes in the fair valuation of equity investments fair valued through other comprehensive income increased equity by EUR 298 (decreased by EUR 203) million. The increase is mainly due to a higher fair valuation of the Group’s shareholding in Pohjolan Voima Oy (PVO), explained especially by higher electricity price forecasts. The changes in the fair valuation of cash flow hedges fair valued through other comprehensive income increased equity by EUR 67 million, mainly driven by stronger SEK and weaker USD. At the end of the year, the ratings for Stora Enso’s rated bonds were as follows: Rating agency Long/short-term rating Valid from Fitch Ratings BBB- (stable) 17 July 2025 Moody’s Baa3 (stable) / P-3 21 November 2024 Our year 2025 Our strategy Our people Governance Shareholders Report of the Board of Directors Sustainability Statement Financial Statements Appendices ≡ U n a u d i t e d 52 ===== SIDA 53 ===== Financial results – Segments Packaging Materials Packaging Materials is a global leader and expert partner in circular packaging providing premium packaging boards, made from virgin and recycled fiber.

Our year 2025 Our strategy Our people Governance Shareholders Report of the Board of Directors Sustainability Statement Financial Statements Appendices ≡ U n a u d i t e d 54 ===== SIDA 55 ===== Capital expenditure Additions to fixed and biological assets including internal costs capitalised in 2025 totalled EUR 746 (1,090) million. The total amount includes additions in biological assets of EUR 69 (81) million. Following the EUR 1 billion investment to convert the remaining idle paper machine to consumer board production, the new line at the Oulu site in Finland started production in the beginning of 2025. The new, flexible line supports the Group’s growth strategy in renewable packaging by providing new capacity for growing packaging segments. The targeted end-use segments are food and beverage packaging, especially frozen and chilled, as well as dry and fast food, mainly in Europe and North America. The line is expected to reach full capacity, 750,000 tonnes annually, during 2027. The EUR 30 million Heinola boiler and fuel handling modification, announced in February 2023, was taken in use during the second half of 2025. The EUR 42 million investment in improvements to fluff pulp production at the Skutskär site in Sweden was completed in the first half of 2025. The ramp-up of the new corrugated packaging site in De Lier in the Netherlands is ongoing and is expected to be completed in 2026. The EUR 30 million upgrade and expansion of the Ostrołęka corrugated plant in Poland is ongoing and is expected to be completed in 2026. Innovation, research and development Stora Enso’s growth focus is on the development of sustainable and resource-efficient packaging applications to replace fossil-based materials, innovative biomaterials for high-end applications, and sustainable wooden-based materials and components that store carbon and improve the energy efficiency of buildings. Stora Enso engages with young and growing companies that are developing technology and solutions aligned with the Company’s core and growth areas, using a venture client approach. The Group’s Innovation and R&D team works closely with strategic partner universities, research institutes, and excellence centres to tackle key scientific questions related to renewable materials. Stora Enso engages in multiple research programmes along the value chain, from forests to products and circular material flows. Stora Enso’s total spend on innovation, research, and development in 2025 was EUR 69 (78) million, equivalent to 0.7% (1.0%) of total sales. Research and development work is fundamental to staying relevant and competitive in relation to customers. In 2025, Stora Enso employed approximately 310 people in research and development. The product innovations and development of services is guided and financed by the business areas. Intellectual property (IP) is an important tool to support Stora Enso’s development of innovative products and processes while safeguarding the Group’s intellectual assets. In 2025, Stora Enso continued to strengthen its patent portfolio by applying for patents for 62 new innovations, primarily in the Biomaterials and Packaging Materials segments. Within biomaterials, the focus was on patents for sustainable battery materials, biobinders, biofoam, and circular chemicals, while the packaging materials patents were mainly related to barriers, board technology, and circular packaging. Stora Enso’s patent portfolio now amounts to over 3,100 applications and granted patents. Employees On 31 December 2025, there were 18,515 (18,558) full-time employees in the Group. The average number of employees in 2025 was 18,877, which is 356 less than a year before. Although the total number of personnel decreased slightly, the acquisition of Junnikkala and the start-up of the new consumer board line at the Oulu site had an increasing effect on personnel. At the end of 2025, the Group’s top four countries in respect to the number of employees were Finland, Sweden, China, and Poland. Nature-related financial disclosures (TNFD) The Taskforce on Nature-related Financial Disclosures (TNFD) is a science- based initiative supported globally by national governments, businesses, and financial institutions. It provides a framework for risk management and disclosure to identify, assess, respond to, and disclose nature-related issues. The TNFD recommendations align with the global policy goals outlined in the Kunming-Montreal Global Biodiversity Framework and are structured around four pillars: Governance, Strategy, Risk & Impact Management, and Metrics & Targets. Stora Enso became a TNFD Early Adopter in 2024 and published its first TNFD-aligned report for the financial year 2024. The Group’s reporting according to the European Sustainability Reporting Standards comprises nature-related disclosures, which are in line with the TNFD recommendations. It is recognised that the nature-related disclosures will evolve as international reporting frameworks continue to develop and more data becomes available. Stora Enso utilise the LEAP (Locate, Evaluate, Assess, and Prepare) framework in the nature-related management and reporting to demonstrate how the Group addresses nature-related impacts, risks, and dependencies. This approach is complemented by in-depth analyses of individual mills within their respective management systems. Stora Enso’s ambition is to establish, maintain, and develop practises and ways of working across its value chain that contribute to positive outcomes in nature. This approach aims to enhance the valuation of nature, while mitigating environmental impacts and preserving biodiversity. In 2025, the Group started developing an approach for biodiversity action plans for prioritised production units. The TNFD index table is available at storaenso.com/annual report. The index provides further references to relevant sections in the Group’s Annual Report. This includes the Sustainability Statement prepared in accordance with the European Sustainability Reporting Standards. Our year 2025 Our strategy Our people Governance Shareholders Report of the Board of Directors Sustainability Statement Financial Statements Appendices ≡ U n a u d i t e d 55 ===== SIDA 56 ===== Risk management Approach to risk management Stora Enso operates globally in the renewable materials industry, serving diverse markets with products and solutions that replace fossil-based materials. These markets are competitive and subject to economic, regulatory, and environmental changes. We define risk as any event or condition that could adversely affect the achievement of our organisational values, strategic or operational objectives. Risks may arise from threats, uncertainties, or missed opportunities related to current or future activities. Stora Enso applies and established Enterprise Risk Management (ERM) Framework to systematically identify, analyse, assess and report risks across strategic, operational, financial and compliance areas. This framework support consistent risk management practices throughout the Group and ensures that risks are managed appropriately. Risk governance The Group Risk Policy, approved by the Board of Directors, establishes Stora Enso’s overarching approach to governance and risk management. It is consistent with the COSO (Committee of Sponsoring Organizations) framework and aligned with ISO 31000 principles. The Board retains ultimate responsibility for the Group’s risk management process and, primarily through Group policies, determines the appropriate and acceptable level of risk. The Financial and Audit Committee assists the Board in monitoring the adequacy and effectiveness of the risk management framework, with particular focus on the management and reporting of financial risks. The Sustainability and Ethics Committee assists the Board in overseeing the management and reporting of sustainability and business ethics risks. The Head of Enterprise Risk Management, reporting to the Executive Vice President, Strategy and Sustainability,is accountable for the design, development, and top-down implementation of the Group risk management framework. Each Business Area and Group Function Head, together with their respective management teams, is responsible for executing the risk management process and ensuring that the framework and related guidelines are effectively cascaded throughout the organisation. Robust risk governance supports Stora Enso’s sustainability objectives and contributes to long-term value creation by ensuring effective oversight, accountability, and proactive management of risks across the Group. Risk management process Risk management is integrated into decision-making and business planning processes. As part of the annual strategy process, each business area and Group function conducts a baseline risk assessment aligned with its key objectives. Guidance on the risk management process is provided in the Enterprise Risk Management (ERM) framework. Business areas and functions identify potential risk events and sources, including changes in internal and external context, underlying causes, and potential impacts. Stora Enso’s risk framework defines the overall risk universe, supporting consistent risk identification, consolidation, and terminology. Risk analysis focuses on understanding risks to inform evaluation and prioritisation. Risks are assessed based on impact and likelihood, often using specific scenarios. Existing risk controls and mitigations are considered to determine the residual risk level. Impact scales cover financial, safety, compliance, and reputational aspects, using both quantitative and qualitative measures. Risk treatment involves selecting appropriate actions, such as avoiding, mitigating, transferring, or accepting risks. For risks exceeding tolerance levels, additional mitigation measures are defined, including responsibilities, timelines, and follow-up actions. After the annual baseline assessment, prioritised and emerging risks, along with related risk treatments, are reviewed during business area meetings twice a year. Despite these measures, some risks remain beyond management’s control. Therefore, Stora Enso cannot guarantee that such risks, if they occur, will not have a material adverse effect on the company’s business, financial position, operating profit, or ability to meet financial obligations. Risk management process Monitor and review Establish the context Communicate and consult Risk assessment Identify Analyse Evaluate Treat risks Our year 2025 Our strategy Our people Governance Shareholders Report of the Board of Directors Sustainability Statement Financial Statements Appendices ≡ U n a u d i t e d 56 ===== SIDA 57 ===== Main risks Reputation Negative impacts on reputation often reflects the combined effects of various types of risks and may result from incidents or non-compliant behaviour by employees, contractors, suppliers or other business partners. This includes failures to comply with norms, laws and regulations, or policy documents. Damage to Stora Enso’s reputation and brand could lead to a loss of investor and customer confidence, resulting in higher cost of capital and decreased revenues. Policies such as the Stora Enso Code and Supplier Code of Conduct ensure that the Board has oversight. Continuous and mandatory training sessions for employees and, occasionally for, suppliers guarantee that the policies are being implemented, and audits are conducted to monitor that Stora Enso’s requirements are met. Stora Enso has established a Speak Up Hotline, through which employees and any third party globally can anonymously report potential non-compliance cases. All reported cases are subject to an established investigation and reporting process, with proven cases leading to actions. Stora Enso continuously engages with its stakeholders to enhance relationships, to respond to developing needs, and inform its strategy. Stakeholder engagement, internal and external, is key to building and fostering a strong corporate reputation. It ensures good communication flows and solid collaborative alliances. Consistently delivering high quality, compliant products and services is the foundation of Stora Enso’s brand reputation. Stora Enso provides visibility into its sustainability roadmap, deliver on its key commitments and comply with the evolving regulatory framework through stringent processes. Finally, the Group ensures strong community outreach and involvement in the areas where is has operations. Strategic risks Macroeconomy, geopolitics, and currency rates Changes in global economic conditions, such as sharp market corrections and foreign exchange volatility, could have a negative and material impact on Stora Enso’s profit, cash flows and financial position. Stora Enso is exposed to several financial market risks, which the Group is responsible for managing under policies approved by the Board of Directors. The objective is to achieve cost-effective funding for Group companies and manage financial risks by using financial instruments to reduce earnings volatility. The main exposures for the Group, besides currency risk, are interest rate risk, liquidity risk, refinancing risk, commodity price risk and credit risk. Financial risks are discussed in detail in note 5.1 Financial risk management. Stora Enso has a diversified portfolio of businesses which mitigates exposure to any one country or product segment. The external environment is continuously monitored and planning assumptions take into account important near- to medium-term and long-term drivers and risks related to key macro-economic factors. Compliance with the Board-approved risk appetite is closely monitored and cash flow and liquidity are actively managed. Stora Enso hedges 15–60% of the highly probable 12-month net foreign exchange flows in main currency pairs. Currency translation risk is reduced by funding assets, whenever economically possible, in the same currency as the asset. The business areas regularly monitor their order flows and other leading indicators, where available, so they can respond quickly to a deterioration in trading conditions. In the event of a significant deterioration in general economic condition and in main leading economic indicators, the Group has the ability to implement cost reduction measures to offset the impact on margins from a decline in sales. Despite the volatility in the macroeconomy, global megatrends drive the demand for renewable materials supporting Stora Enso’s growth and value creation. A diverse business portfolio and geographical presence, competitive strength and resilient balance sheet reduce the Group’s risk exposures. Climate change – physical impacts Long-term (25–30 years) changes in precipitation patterns, periods of drought, storms, more frequent extreme weather events and higher average temperatures, could cause damage to operations, forests and tree plantations. Such developments may increase the risk of forest fires, insect outbreaks, wind damages and other climate-related impacts affecting forests asset values and regional wood prices. Milder winters could also impact on the harvesting and transport of wood, as well as related costs in northern regions. More frequent extreme weather events also increase the risk of disruptions in the production, logistics and supply of raw materials and energy. Physical risks are largely subject to risk transfer and therefore covered by Stora Enso’s property and business interruption insurance programmes. With regards to forest and plantation assets, Stora Enso benefits from strategic resilience through geographical diversification within its asset portfolio. Diligent plantation planning ensures the avoidance of frost sensitive areas, and R&D programmes are applied to increase tolerance to extreme temperatures. Stora Enso maintains a diversity of forest types and structures and enforces diversification in wood sourcing. Wood harvesting in soft soils involves the implementation of best practices guidelines. Nordic forests in Finland and Sweden could also benefit from increased heat summation and longer growing seasons, leading to accelerated forest growth with a direct positive impact on the value of Stora Enso’s own forest assets and an indirect impact related to market wood availability and costs. Biodiversity loss Stora Enso’s forestry and industrial operations have an impact on biodiversity. At the same time, Stora Enso’s business depends on raw material inputs from natural capital, such as wood and fresh water. Biodiversity is essential for maintaining the stability of ecosystem processes in changing environments. Biodiversity loss can negatively impact the value of Stora Enso’s forest assets and acceptability of wood as a raw material. Read more in the TNFD chapter. Stora Enso is committed to achieving a net positive impact on biodiversity in its own forests and plantations through active biodiversity management. Biodiversity management is an integral part of all Stora Enso’s forest and plantation management practices. Operations are supported by new technologies and digitalisation, as well as continuous research and innovation. For example, Stora Enso’s forest units have established special programmes focusing on biodiversity management. In addition, Stora Enso uses tools, such as wood traceability and forest certification, and engages in collaboration with various stakeholders to protect ecosystems and safeguard natural resources. Sustainable forest management maintains forest health and vitality. Active biodiversity management and conservation in Stora Enso’s forest operations, such as spatially optimising the volume of deadwood and protection of key habitats, contribute to a positive biodiversity impact. Healthy and biodiverse forests improve resilience against external calamities and a changing climate. Competition and market demand The packaging, pulp, paper, and wood products industries are mature, capital-intensive and highly competitive. Stora Enso’s principal competitors include several large international forest products companies and numerous regional and more specialised competitors. Customer demand is influenced by general economic conditions and inventory levels, which in turn affect product price levels. Product prices, which tend to be cyclical, are affected by capacity utilisation, which decreases in times of economic slowdowns. Price changes differ between products and geographic regions. See Table 1 for the operating profit sensitivity to a +/- 10% change in either price or volume for different segments. The ability to respond to changes in product demand and consumer preferences and to develop new products on a competitive and economic basis requires innovation, continuous capacity management, and structural development. Risks related to factors such as demand, price, competition, and customers are regularly monitored by each business area and unit as a routine part of business management. These risks are also continuously monitored and evaluated at the Group level to gain a perspective on Stora Enso’s total asset portfolio and overall long-term profitability potential. Stora Enso, one of the largest private forest owners in the world, also benefits from a strategic renewable resource base. The Group’s expertise in wood and wood-based renewable materials is focused on responding to changing customer and consumer preferences, driven by climate change. Products based on renewable materials with a low carbon footprint help customers and society at large to reduce CO2 emissions by providing an alternative to solutions based on fossil fuels or other non- renewable materials. Risk Description Mitigation Opportunity Our year 2025 Our strategy Our people Governance Shareholders Report of the Board of Directors Sustainability Statement Financial Statements Appendices ≡ U n a u d i t e d 57 ===== SIDA 58 ===== Regulatory changes Stora Enso’s businesses may be affected by political or regulatory developments in any of the countries or jurisdictions where it operates, including changes to forest, biodiversity, environmental, fiscal, tax, or other regulatory regimes. Potential impacts include higher costs and capital expenditures to meet new requirements, expropriation of assets, imposition of royalties or other industry-specific taxes, and requirements for local ownership or value- added processing. Active monitoring of regulatory and political developments in the countries where Stora Enso operates as well as participation in policy development primarily through industry associations and other partnership programmes are important risk mitigation measures related regulatory changes. Regulatory changes can also present significant opportunities by driving market growth for sustainable products and creating competitive advantage through resource efficiency and renewability. Strategic investments To succeed in implementing its strategy, Stora Enso must understand the needs of its customers and find the best way to serve them with the right offering and the right production asset portfolio. Failure to complete strategic projects in accordance with the agreed schedule, budget or specifications can, therefore, have serious impacts on Stora Enso’s financial performance. Significant, unforeseen changes in costs or an inability to sell the envisaged volumes or achieve planned price levels may prevent Stora Enso from achieving its business goals. Risks are mitigated through thorough and detailed pre-feasibility and feasibility studies which are prepared for each large investment. Investment guidelines stipulate the process, governance, risk assessment, management and monitoring procedures for strategic projects, including climate related risk factors. The guidelines also require the calculation of potential cost and income for CO2 emissions as part of the investment proposal, Environmental and Social Impact Assessments (ESIAs) are conducted for all new projects that could cause significant adverse effects in local communities. Post completion audits are carried out for all significant investments. Replacing fossil-based materials by innovating and developing new products and services based on wood and other renewable materials. Mergers, acquisitions, and divestments Failure to realise the expected benefits from the acquisition of a company or asset can have serious financial impacts on Stora Enso. The Group may also find itself liable for past acts or omissions of the acquired business, without any adequate right of redress. Failure to achieve expected values from the sales of assets or deliveries beyond the expected receipt of funds may also impact Stora Enso’s financial position. Divestments or business restructuring may involve additional costs due to historical and unaccounted liabilities as well as reputational impacts. Rigorous M&A guidelines, including due diligence procedures are applied to the evaluation and execution of all acquisitions. Structured governance and policies, such as the policy for responsible right-sizing, are followed when making restructuring decisions. A strong balance sheet and cash flow enable value enhancing M&A, when the timing and opportunity are right. Operational risks Personal safety – employees and wider workforce Failure to maintain high levels of safety management can result in harm to Stora Enso’s employees and contractors, as well as to communities near our operations and the environment. Impacts in addition to physical injury, health effects and environmental damage could include liability to employees or third parties, damage to reputation, or an inability to attract and retain skilled employees. Government authorities could also enforce the closure of our operations on a temporary basis. Personnel safety and security can never be compromised. Therefore, Stora Enso must be aware of potential safety risks and provide adequate guidelines to people for managing risks related to, for example, travelling, working, and living in countries with security or crime concerns. Stora Enso’s goal is to provide an accident-free workplace. Encouraging a Group-wide safety culture means that everyone is responsible for making every workday healthy and safe – from top management throughout the Group. The approach to safety extends to contractors, suppliers, and on-site visitors. Everyone is encouraged to share feedback and suggest ideas for further improving safety. Additionally, safety is promoted among contractors and suppliers through a dedicated e-learning. The Group also emphasises the importance of safety by asking suppliers to provide information on their safety performance in the tendering process. Stora Enso’s Health and Safety Policy defines the objectives for safety management, as well as the governance model for managing health and safety topics in practice and integrating them into annual planning and reporting. Achieving strong health and safety performance can enhance Stora Enso’s employer brand, as well as improve engagement, efficiency and productivity. Physical assets Stora Enso’s production facilities carry inherent risks of equipment failure or off-spec operations, which can lead to poor product quality, unplanned downtime, lower output, and higher costs. Such issues may affect delivery commitments and business objectives. Risks can arise from design deficiencies, operational failures, or practices, and also include hazards such as fire and explosions. The most significant exposures are in integrated pulp and board production and related energy generation. Protecting production assets and ensuring business continuity are top priorities for Stora Enso. The Group uses structured methods to identify, measure, and control process risks, working with insurance providers and loss prevention experts. Annual technical inspections, risk improvement programmes, and cost-benefit analyses are supported by internal reporting and assessment tools. Property loss prevention guidelines, fire and machinery risk assessments, and targeted programmes help reduce exposure. Planned maintenance stoppages are essential for equipment reliability and safety. Preventive maintenance programmes and spare part criticality analyses are utilised to secure the high availability and efficiency of key machinery. Product safety Some of Stora Enso’s products are used for packaging liquids and food consumer products, where any defects could affect health or packaging functionality, leading to costly product recalls. Wood products are used in construction, potentially exposing Stora Enso to product liability related to failures in structural design, product selection or installation. Failure to ensure product safety could result in recalls involving significant costs including compensation for customers’ indirect expenses, and reputational damage. Mills producing food and drink contact products have established certified hygiene management systems based on risk and hazard analysis. To ensure product safety, Stora Enso actively participates in CEPI (Confederation of European Paper Industry) working groups on chemical and product safety. In addition, Stora Enso mills have certified ISO quality management systems. Contractual liability limitation and insurance protection further mitigate Stora Enso’s risk exposure. Stora Enso recognises the opportunity of differentiation and value creation through superior product quality and the highest level of product conformity. Risk Description Mitigation Opportunity Our year 2025 Our strategy Our people Governance Shareholders Report of the Board of Directors Sustainability Statement Financial Statements Appendices ≡ U n a u d i t e d 58 ===== SIDA 59 ===== People and capabilities Competition for personnel is intense and Stora Enso may, in the long term, not be successful in attracting or retaining qualified personnel. The loss of key employees, the inability to attract new or adequately trained employees, or a delay in hiring key personnel could seriously harm Stora Enso’s business and impede reaching the Group’s strategic objectives. Labour market disruptions and strikes, especially in times of restructuring and redundancies due to divestments and mill closures or during labour market negotiations, could also have adverse material effects on Stora Enso’s business, financial position and profitability. Stora Enso manages the risks and loss of key talents through a combination of different actions. Some of the activities aim towards making the Stora Enso employer brand better known both internally and externally, globalising some of the remuneration practices and intensifying the efforts to identify and develop talents. Finally, the Group actively focuses on talent and management assessments, including succession planning for key positions. The majority of employees are represented by labour unions under several collective agreements in different countries where Stora Enso operates, thus relations with unions are of high importance to manage labour disruption risks. Stora Enso recognises that skilled and dedicated employees are essential for success. Engaged, high-performing individuals drive the implementation of transformation strategy and contribute to commercial success. Sourcing Increasing input costs or challenges in availability of materials, goods and services may adversely affect Stora Enso’s profitability. Securing access to reliable, low-cost supplies and proactively managing costs and productivity are key priorities. Reliance on external energy suppliers also makes Stora Enso susceptible to fluctuations in energy market prices. Additionally, the supply chain faces heightened risks of disruption due to cyber incidents, political instability, and other factors related to global trade. See Table 2 for Stora Enso’s major cost items. In many areas Stora Enso depends on suppliers and their ability to deliver products or services on time and at required quality. Key inputs include fiber, chemicals, energy, and machinery and equipment for capital investment projects. Increased demand for carbon neutral primary and secondary biomass fuels may drive up energy costs. Critical services, such as transport and outsourced business support, are also essential. For some of these inputs, reliance on a limited number of suppliers poses a risk. Input cost volatility is closely monitored at the business unit, business area and Group levels, and a consistent long-term energy risk management approach is applied. Price and supply risks are mitigated through increased in-house generation, shareholding in competitive power assets such as PVO/TVO, physical long-term contracts, and financial derivatives. Stora Enso hedges price risks in raw material and end-product markets and supports the development of financial hedging mechanisms. A wide range of suppliers is utilised and monitored to avoid situations that might jeopardise continued production, business transactions, or development projects. Suppliers and subcontractors are required to comply with Stora Enso’s sustainability standards, as they form part of the Group’s value chain. These sustainability requirements, along with audit schemes encompass raw materials, and other goods and services procured. Suppliers are assessed for risks related to environmental, social and business practices using an internal risk assessment tool. Supplier Code of Conduct audits are conducted for high-risk suppliers, and findings from these audits are followed-up. If mitigation is not possible, supplier contracts may be terminated. Stora Enso also has the opportunity to add value and drive innovation globally by building strong, measurable relationships with top suppliers, enforcing harmonised sourcing processes to enhance capabilities, improve tender quality, reduce costs, and nurture sustainable suppliers. Information technology, security, and digitalisation Stora Enso is dependent on IT systems for both internal and external communications and for the day-to-day management of its operations. Information systems, personnel, and facilities are subject to cyber security risks, such as ransomware. In addition, the accidental disclosure of confidential information due to a failure to follow information handling guidelines, as a result of an accident or criminal act, may result in financial damage, penalties, disrupted or delayed launch of new business lines or ventures, loss of customer and market confidence, loss of research secrets, breach of data privacy regulations, and other business-critical information. The management of risks is actively pursued in the Information Risk Management System, and best practice change management and project methodologies are applied. We actively work to prevent cybercrime. Several security controls have been implemented to strengthen the protection of confidential information and to ensure compliance with international regulations. Opportunities may arise from efficient operations, performance optimisation, innovative product offerings. New customer services through digitisation also present potential benefits. Additionally, sophisticated IT systems, as well as new technologies offering significant potential for higher level of process optimisation and automatisation. These improvements can generate new business and enhance value propositions for customers and consumers. Ethics and compliance Stora Enso operates in a highly regulated business area and is therefore exposed to risks related to breaches of applicable laws and regulations, including those related to capital markets regulation, company and tax laws, customs, the environment, human rights, and safety. This also covers areas addressed by policies such as the Stora Enso Code and Business Practice Policy, including fraud, anti-trust, corruption, conflict of interests, and other forms of misconduct. Breaches may lead to high compliance and remediation costs, including prosecution costs, fines, penalties, and contractual, financial, and reputational damage. Stora Enso’s Ethics and Compliance Programme, which includes policy setting, promoting values, training, knowledge sharing and grievance mechanisms, is continuously updated and developed. Other compliance mechanisms include Stora Enso Group’s internal control system and Internal Audit assurance, as well as the Supplier Code of Conduct in supplier contracts, risk assessments, trainings and audits. In response to capital markets regulations, Stora Enso’s Disclosure Policy emphasises the importance of transparency, credibility, responsibility, proactivity and interaction. Environmental risks are minimised through environmental management systems and environmental due diligence for acquisitions and divestments, and indemnification agreements where effective and appropriate remediation projects are required. Special remediation projects related to discontinued activities and mill closures are executed based on risk assessments. Focusing on ethics in a wider sense, rather than merely complying with laws and regulations, promotes a value-driven and more successful business, fosters accountability, and enhances corporate reputation.

Governance Stora Enso complies with the Finnish Corporate Governance Code 2025 issued by the Securities Market Association. The Code is available at cgfinland.fi. Stora Enso also complies with the Swedish Corporate Governance Code, with the exception of the deviations listed in Appendix 1 of the Corporate Governance report. The deviations are due to differences between Swedish and Finnish legislation, governance code rules and practices, and in these cases Stora Enso follows the practice in its domicile. The Swedish Code is issued by the Swedish Corporate Governance Board and is available at corporategovernanceboard.se. Our year 2025 Our strategy Our people Governance Shareholders Report of the Board of Directors Sustainability Statement Financial Statements Appendices ≡ U n a u d i t e d 61 ===== SIDA 62 ===== Related party transactions Stora Enso’s Guideline for Related Party transactions addresses the principles and processes for related party transactions in Stora Enso Group, including decision-making, identifying related party transactions, reporting and monitoring of related party transactions. Any transaction undertaken with a related party, which is not undertaken on market terms or which does not form part of the Company’s ordinary course of business shall be reported to the Financial and Audit Committee and approved by the Board of Directors. Furthermore, Board members and members of the Group Leadership Team are subject to additional transparency requirements to ensure proper review of transactions involving them, their close family or a related entity. For more details on related party transactions, see the Financial Statement, note 6.3 and the Parent company financial statements note 26. Legal proceedings Contingent liabilities Stora Enso has undertaken significant restructuring actions in recent years which have included the divestment of companies, sale of assets and mill closures. These transactions include a risk of possible environmental or other obligations the existence of which would be confirmed only by the occurrence or non-occurrence of one or more uncertain future events not wholly within the control of the Group. A provision has been recognised for obligations for which the related amount can be estimated reliably and for which the related future cost is considered to be at least probable. Stora Enso is party to legal proceedings that arise in the ordinary course of business and which primarily involve claims arising out of commercial law. The management does not consider that liabilities related to such proceedings before insurance recoveries, if any, are likely to be material to the Group’s financial condition or results of operations. Veracel On 11 July 2008, Stora Enso announced that a federal judge in Brazil had issued a decision claiming that the permits issued by the State of Bahia for the operations of Stora Enso’s joint operations company Veracel were not valid. Veracel disputed the decision and filed an appeal against it. On 10 July 2025, Veracel’s appeal was upheld by the Federal Court, and the regularity of all the environmental licensing of the project was recognised, and the fine of BRL 20 (EUR 3) million was annulled. The decision was not appealed to the Higher Courts, and the ruling is final. Changes in the Group management Niclas Rosenlew started as CFO and a member of the Group Leadership Team on 13 January 2025. As of 1 January 2026, he assumed additional responsibilities and represents the Communications and Brand organisations in the Group Leadership Team.

Outlook Short-term outlook • Markets remain challenging, with low consumer confidence. Geopolitical volatility results in decreased predictability. • Packaging and pulp market demand is expected to remain stable at low levels. • The ramp-up of the new consumer board production line at the Oulu site in Finland continues. The EBIT headwind is expected to gradually decrease as we improve the technical performance of the production line. In Q1, we expect a negative impact of EUR 15–30 million on adjusted EBIT. • The divestment of 175,000 hectares of forest assets in Sweden, completed in 2025, will result in a reduction of annual adjusted EBIT of approximately EUR 20 million, with an estimated quarterly effect of approximately EUR 5 million. • The operating income from emission rights in 2025 were about EUR 72 million, distributed evenly throughout the year. For 2026, the income from the sale of emission rights is projected to decrease to EUR 10–20 million. This decline results from changes in the EU ETS (Emissions Trading S c h e m e ) r u l e s : s e v e r a l s i t e s w i l l l o s e t h e i r f r e e C O ₂ a l l o w a n c e a l l o c a t i o n s from 2026 onward, as their emissions are now more than 95% biogenic, demonstrating the success of long-term emission-reduction initiatives. • In the first quarter of 2026 we will introduce a revised reporting structure, as presented in the CMD in November 2025. The packaging business areas will be consolidated into Consumer Packaging and Integrated Packaging segments. In addition, we will report Biomaterials and Other.

These numbers are net of hedges and assuming no changes occur other than a single currency exchange rate movement in an exposure currency. Short-term risks The geopolitical unrest could have an adverse impact on the Group. Potential trade tariffs, retaliatory measures, conflict-related risks to people, operations, trade credit, cyber security, supply, and demand, could also affect the Group negatively. The risk of a prolonged global economic downturn and recession, sudden interest rate changes, currency fluctuations, trade union and political strike actions, and logistical chain disruptions could all adversely affect the Group’s profits, cash flow and financial position, as well as access to material, flow of goods and transport. Macroeconomic and geopolitical disruption may increase costs, add complexity, and lower short-term visibility, which could further impact market demand, prices, profit margins, and volumes of the Group’s products. New capacity and volume entering the market might distort demand, volumes, inventories and pricing. Moreover, forced capacity cuts might further impact on profitability. There is a risk of continued price volatility for raw materials such as wood, chemicals, other components and energy in Europe. The continued tight wood market, especially in the Nordics, could cause increased costs, limit harvesting and cause disruptions such as delays and/or lack of wood supply to the Group’s production sites. Regulatory or similar initiatives might challenge the Group’s strategy, growth and operations. Other risks and uncertainties include, but are not limited to; general industry conditions, unanticipated expenditures related to the cost of compliance with existing and new environmental and other governmental regulations, and related to actual or potential litigation; material process disruption at Stora Enso’s manufacturing facilities with operational or environmental impacts; risks inherent in conducting business through joint ventures; and other factors. Proposal for the distribution of dividend Stora Enso Oyj’s Annual General Meeting (AGM) will be held on Tuesday 24 March 2026 at 16:00 EET at Finlandia Hall in Helsinki, Finland. More information is available at storaenso.com/agm. The parent company distributable shareholders’ equity on 31 December 2025 amounted to EUR 1,496,703,545.00 including the profit for the period of EUR 251,991,875.65. The Board of Directors proposes to the AGM that a dividend of EUR 0.25 per share be distributed on the basis of the balance sheet adopted for the year 2025. This would correspond to EUR 197,154,996.75 in aggregate for all currently registered 788,619,987 shares, which would leave EUR 1,299,548,548.25 in distributable shareholders’ equity. The Board of Directors proposes that the dividend be paid in two instalments. The first dividend instalment, EUR 0.13 per share, is proposed to be paid to shareholders who on the record date of the first dividend instalment, 26 March 2026, are registered in the shareholders’ register maintained by Euroclear Finland Oy or in the separate register of shareholders maintained by Euroclear Sweden AB for Euroclear Sweden registered shares. The Board of Directors proposes to the AGM that the first instalment of the dividend be paid on or about 8 April 2026. The second dividend instalment, EUR 0.12 per share, is proposed to be paid to shareholders who on the record date of the second dividend instalment on 25 September 2026 are registered in the shareholders’ register Our year 2025 Our strategy Our people Governance Shareholders Report of the Board of Directors Sustainability Statement Financial Statements Appendices ≡ U n a u d i t e d 63 ===== SIDA 64 ===== maintained by Euroclear Finland Oy or in the separate register of shareholders maintained by Euroclear Sweden AB for Euroclear Sweden registered shares. The Board of Directors proposes that the second dividend instalment would be paid on or about 2 October 2026. Dividends payable to Euroclear Sweden registered shares will be forwarded by Euroclear Sweden AB and paid in Swedish crowns. Dividends payable to ADR holders will be forwarded by Citibank N.A. and paid in US dollars. Stora Enso’s policy is to distribute 50% of earnings per share (EPS) excluding fair valuation over the cycle. In 2025, EPS excluding fair valuation was EUR 0.41. Events after the reporting period New reporting structure Stora Enso implemented a new financial reporting structure effective 1 January 2026, aligning with the Group’s enhanced focus on renewable materials and packaging. The new reporting segments are: • Consumer Packaging (comprising the Cartonboard and the Foodservice and Liquid Board business areas) • Integrated Packaging (comprising the Containerboard and the Packaging Solutions business areas) • Biomaterials • Other (including the Wood and Energy business area and the Group’s administration) The Swedish forest assets and the Central European sawmilling and building solutions operations (currently under strategic review) will be reported under the segment Other. New financial targets To drive stronger performance and sharpen its focus on packaging, the Group has updated its financial targets to reflect its new strategy. Targets over the business cycle • Adjusted EBIT margin: >10% • Revenue growth: >4% • Payout ratio: >50% • Net debt to adjusted EBITDA ratio: <1x Our year 2025 Our strategy Our people Governance Shareholders Report of the Board of Directors Sustainability Statement Financial Statements Appendices ≡ U n a u d i t e d 64 ===== SIDA 65 ===== Alternative performance measures According to the European Securities and Markets Authority (ESMA) Guidelines, an alternative performance measure is understood as a financial measure of historical or future financial performance, financial position, or cash flows, not defined under IFRS. Used together with the IFRS measures, alternative performance measures provide meaningful supplemental information to the management, investors, analysts and other parties with regards to the financial development of the business operations. Operating result (IFRS) Net result for the period excluding income tax and net financial items (finance costs). Used in combination with below measures to determine the profitability of the Group. Adjusted EBIT Operating result (IFRS) excluding items affecting comparability (IAC) and fair valuations and non-operational items (FV) of the line-by-line consolidated entities and Stora Enso’s share of operating result excluding IAC and FV of its associated companies. The Group’s key non-IFRS performance metric, which is used to evaluate the performance of operating segments and, in combination with below ratios, to steer allocation of resources to them. Adjusted EBITDA Operating result (IFRS) excluding silviculture costs and damage to forests, fixed asset depreciation and impairment, IACs and FV. The definition includes the respective items of subsidiaries, joint arrangements and associated companies. Used by management to analyse the business and, from time- to-time, for short term and long-term target setting. Adjusted return on capital employed (ROCE), LTM3 (%) Adjusted EBIT3 x 100 Capital employed1 Used for long-term Group financial targets setting. Adjusted return on operating capital (ROOC), LTM3 (%) Adjusted EBIT3 x 100 Operating capital 1 Used for long-term divisional financial targets setting. Return on equity, ROE, LTM3 (%) Net result for the period x 100 Total equity1 A measure of the profitability in relation to equity. Net debt Interest-bearing liabilities – interest-bearing assets, marked with “I” in the statement of financial position. Used for long-term Group financial targets setting. Net debt/equity ratio Net debt Equity2 Used for long-term Group financial targets setting. Net debt/last 12 months’ adjusted EBITDA ratio Net debt LTM adjusted EBITDA Used for long-term Group financial targets setting. Earnings per share (EPS) excluding FV Net result for the period excluding fair valuations and non-operational items after tax divided by the weighted average number of shares Stora Enso's dividend policy is to distribute 50% of earnings per share (EPS) excluding fair valuation over the cycle. Operating capital and capital employed Operating capital is comprised of items marked with “O” in the statement of financial position. Capital employed = Operating capital – Net tax liabilities. Net tax liabilities are marked with "T" in the statement of financial position. Used for long-term Group financial targets setting. Items affecting comparability (IAC) The most common IAC are significant capital gains and losses, impairments or impairment reversals, disposal gains and losses relating to Group companies, provisions for planned restructurings, environmental provisions, changes in depreciation due to restructuring and penalties. In order for qualifying cases to be considered as items affecting comparability, a materiality threshold will be applied of at least EUR 4 million for Packaging Materials, EUR 2 million for Biomaterials, and EUR 1 million for the rest of the divisions including segment Other. Represent certain significant items, identified by the management, considered not indicative of the operating business performance due to their nature and/or frequency. Fair valuations and non-operational items (FV) Fair valuations and non-operational items include non-cash income and expenses related to CO2 emission rights and liabilities, non-operational fair valuation changes of biological assets, adjustments for differences between fair value and acquisition cost of forest assets upon disposal and the Group’s share of income tax and net financial items of associated companies. Non-operational fair value changes of biological assets reflect changes made to valuation assumptions and parameters. The adjustments for differences between fair value and acquisition cost of forest assets upon disposal are a result of the fact that the cumulative non-operational fair valuation changes of disposed forest assets were included in previous periods in IFRS operating result (biological assets) and other comprehensive income (forest land) and are included in adjusted EBIT only at the disposal date (for non-strategic forest assets disposals). Represent adjustments for certain items considered by the management less relevant for understanding operating business performance. These adjustments result in differences in the recognition and measurement principles applicable under IFRS. Operational fair value change of biological assets Operational fair value changes of biological assets contain all other fair value changes (see above about non-operational fair value changes of biological assets), mainly due to inflation and differences in actual harvesting levels compared to the harvesting plan. The long-term value change of the growing forests is an important component of the forestry business profitability.

Cash flow after investing activities (non-IFRS) is equal to cash flow from operations (non-IFRS) minus cash spent on intangible assets, property, plant and equipment, and biological assets and acquisitions of associated companies. These are measures of cash generation, working capital efficiency and capital expenditure outflows. Capital expenditure Capital expenditure on fixed assets includes investments in and acquisitions of tangible and intangible assets as well as internally generated assets and capitalised borrowing costs, net of any related subsidies. Capital expenditure on leased assets includes new capitalised leasing contracts. Capital expenditure on biological assets consists of acquisitions of biological assets and capitalisation of costs directly linked to growing trees in plantation forests. The cash flow impact of capital expenditure is presented in cash flow from investing activities, excluding lease capex, where the cash flow impact is based on paid lease liabilities and presented in cash flow from financing and operating activities. A measure of the operating business investments capitalised as tangible and intangibles assets. Fixed costs Maintenance, personnel and other administration type of costs, excluding IAC and FV.

It follows the same consolidation principles as the Financial Statements prepared in accordance with the IFRS Accounting Standards. Unless otherwise stated, the Group’s consolidated performance figures expressed in this report relate to the parent company, Stora Enso Oyj, and all companies in which the Group holds 50% or more of the voting rights, directly or indirectly. For additional information on Group’s structure, see Financial Statements, note 6.2 Group structure. Stora Enso has two joint operations, Veracel in Brazil and Montes del Plata in Uruguay. In both companies, Stora Enso holds a 50% ownership. In the Financial Statements, the joint operations are recognised and consolidated based on the Group’s share of the assets, liabilities, revenues, expenses, and cash flows of the joint operation. To ensure consistency with financial reporting, the Sustainability Statement covers information proportional to Group’s ownership in the joint operations in the following ESRS disclosure requirements: E1-5, E1-6, E1-7, E2-4, E3-4, E4-5, E5-4, E5-5, and S1-6 (total number of employees). The above environmental disclosure requirements include the intensity ratios related to the Group’s financial revenue. For additional information on consolidation principles, see Financial Statements, note 1.1 Accounting principles. Stora Enso does not have full authority over the daily operations of its joint operations, and as these operations are not governed by Stora Enso’s policies, internal controls, or targets, most ESRS reporting requirements for joint operations are not applicable. The same principle applies to financial reporting, where the Group’s joint operations follow their own financial risk policies, which may differ from those of Stora Enso. Unlike financial reporting, where joint operations comply with IFRS accounting standards, they do not adhere to ESRS. Following the double materiality principle, the Sustainability Statement contains relevant upstream and downstream value chain information where necessary to understand the Group’s material impacts, risks, and opportunities and to provide information that meets the qualitative characteristics outlined in the Corporate Sustainability Reporting Directive (CSRD). In the descriptions of material topics, joint operations are referred to as ‘joint operations’ to distinguish them from the Group’s own operations, over which the Group has full authority regarding the operating policies. Due to the sensitivity of information, Stora Enso has exercised the option not to disclose specific details related to intellectual property, know-how, or the outcomes of innovation. In accordance with the Finnish Accounting Act chapter 7 13 § (21.12.2023/1249), Stora Enso does not disclose information on impending developments or matters under negotiation, and has also opted to omit value chain metrics. The connectivity of the ESRS disclosures with the Group’s Financial Statements is indicated through guidance directing readers to additional information, which is not in the scope of ESRS reporting. This Sustainability Statement has been assured by an independent third- party assurance provider in accordance with the Finnish Auditing Act. PricewaterhouseCoopers Oy has provided a level of Limited Assurance, using the ESRS Standards and the requirements of the delegated acts of the Taxonomy Regulation (EU) 2021/2178 as criteria, covering the Sustainability Statement as defined under BP-1. PricewaterhouseCoopers Oy applies the International Standard on Quality Management (ISQM) 1. Additionally, a level of Reasonable Assurance, using the GHG Protocol as criteria, has been provided for Stora Enso’s reporting on direct and indirect greenhouse gas (GHG) emissions (Scope 1 and 2, market-based). Stora Enso’s Science-Based climate targets align with the GHG Protocol and therefore deviate from the ESRS consolidation principle in terms of joint operations, see ESRS E1-6. The Assurance Reports are available on page 211 of the Annual Report. Disclosures in relation to specific circumstances (BP-2) The Sustainability Statement fulfils the characteristics of specific circumstances in some disclosures. Due to the nature of the Group’s operations, time horizons differ from the definitions provided by CSRD. For risks, Stora Enso defines short-term as up to one year, medium-term as two to ten years, and long-term as ten years or more. This aligns with Stora Enso’s enterprise risk management process. Stora Enso applies phased-in provisions in line with the ESRS1 Phased-in Disclosure Requirements Appendix C (EU 2025/1416 delegated regulation amendment to 2023/2772) for the following disclosures: E2-6, E3-5, E4-6, E5-6, S1-7, S1-8 (covers only EEA countries), S1-11, S1-13, and S1-14 (88 d, e). When reporting involves estimated value chain data, outcome uncertainty, or disclosures required by other legislation or accepted sustainability standards, the relevant information is presented within the accounting principles section for each metric. In ESRS E1-6, the metrics related to Scope 3 are subject to a higher level of measurement uncertainty, due to the data encompassing the full value chain. The Our year 2025 Our strategy Our people Governance Shareholders Report of the Board of Directors Sustainability Statement Financial Statements Appendices ≡ A s s u r e d 69 ===== SIDA 70 ===== expected reductions in Stora Enso's carbon reduction pathway for 2030 (presented as graph in ESRS E1-4) are based on various assumptions and estimates that are believed to be reasonable, though actual result and timing could differ from these. The estimates, judgments and assumptions are reviewed regularly and updated when deemed necessary. Unless otherwise stated, the metrics disclosed in the Sustainability Statement have not been validated by an external body other than the assurance provider. Changes in presentation of sustainability information ESRS E1-3 Reductions by Scope 1 and 2 decarbonisation levers In 2025, Stora Enso adjusted its approach to analysing emission reductions per decarbonisation lever, resulting in adjustments between levers but no change to the total reduction achieved. ESRS E1-6 Total GHG emissions disaggregated In 2025, Stora Enso's disaggregated GHG emissions are presented following the financial consolidation scope, in alignment with ESRS standards (2024 reporting followed GHG Protocol). Under this change, joint operations are consolidated line by line in Scope 1 and 2, rather than Scope 3 (as classified by the GHG Protocol). This technical adjustment reallocated emissions between scopes but did not affect the total GHG emissions.

Both policies are approved by the Board of Directors. The duties of the various bodies within Stora Enso are determined by the laws of Finland and by the company’s Corporate Governance Policy, which complies with the Finnish Companies Act and the Finnish Securities Market Act. The working order of the Board sets out the Board’s working practices, while the tasks and responsibilities of the Board committees are defined in their respective charters. The Board’s work is supported by its committees. Executive management’s role to monitor, manage and oversee impacts, risks and opportunities The CEO is responsible for the day-to-day management of the company in accordance with the Finnish Companies Act and the instructions and orders issued by the Board. The CEO is also responsible for overseeing effective risk management and internal controls over financial and sustainability reporting. The Group Internal Control, under Group Assurance and supervised by the CFO, is accountable for internal control governance, processes and tools.

The CEO holds ultimate responsibility for the successful implementation of the company’s sustainability agenda. The EVP Legal, General Counsel, is responsible for ethics and compliance matters at Stora Enso and reports to the CEO. To ensure control over the management of impacts, risks, and opportunities, Stora Enso has set procedures to update the Board on incidents related to safety and environmental non-compliances. The Financial and Audit Committee supports the Board in monitoring the risk management process within Stora Enso, particularly with regard to the management and reporting of risks that have a significant financial impact. Responsibility for maintaining effective risk management is delegated to the CEO. Both the Group Leadership Team and the Board of Directors are regularly updated on sustainability progress and other topical issues. The Group Leadership Team members present sustainability targets to the Board, first reviewed by the Sustainability and Ethics Committee and then approved by the Board of Directors. The Board of Directors receives quarterly updates on performance against the targets. Skills and expertise of the Board to oversee sustainability matters The Sustainability and Ethics Committee comprises two to four Board members who are nominated annually by the Board. At least one Committee member is expected to have sufficient prior knowledge and experience in handling sustainability and business ethics matters. To ensure the Board’s insight and competence on the Company’s material sustainability-related topics, the Board regularly reviews and discusses material impacts, risks and opportunities, targets, and external reporting as described below under ESRS 2 GOV-2. In 2025, seven of the Board members possessed sustainability or ESG- related expertise as their primary skill. Additionally, three of the Board members had specific expertise in sustainability-driven innovation. These skills are aligned with the strategic topics identified as part of Stora Enso’s double materiality assessment: climate change, biodiversity and circularity. Three out of the four members of the Sustainability and Ethics Committee Our year 2025 Our strategy Our people Governance Shareholders Report of the Board of Directors Sustainability Statement Financial Statements Appendices ≡ A s s u r e d 70 ===== SIDA 71 ===== possessed expertise in governance and compliance as their primary skill, and all the members of the Financial and Audit Committee held this expertise.

In 2025, these included: • update and discussion on climate resilience plan • implementation of the due diligence process in accordance with the Corporate Sustainability Due Diligence Directive, and • ESG update on market information. The Board approves the double materiality assessment as described in ESRS IRO-1. The outcome of the assessment is disclosed under ESRS 2 SBM-3. The Board supervises the operation and management of Stora Enso and decides on significant matters relating to strategy, investments, organisation, and finance. Information on the development of essential risk areas, as well as executed and planned activities in these areas are regularly communicated to the Financial and Audit Committee. Sustainability and Ethics Committee receives regular updates on material sustainability topics, including related impacts, risks and opportunities as described above. The two Committees present a report on each meeting to the Board to be utilised in the Board’s approval, supervisory and decision-making processes. Risks are reviewed jointly with the Financial and Audit Committee and Sustainability and Ethics Committee to ensure a holistic approach to overseeing Company risks. In accordance with the Board’s working order, matters handled in the meetings include, among others, the approval of major investments and divestments. The Group’s Investment Guidelines address sustainability matters to be considered, but do not provide specific guidance on potential trade-offs. Integration of sustainability-related performance in incentive schemes (GOV-3) The Remuneration Policy describes Stora Enso’s main principles and the decision-making process for the remuneration of the members of the Board and the President and CEO. The performance metrics defined in the policy include sustainability targets as decided by the Board. Since 2022, sustainability measures have been part of the Company’s variable remuneration. The sustainability performance criteria align with Stora Enso’s key sustainability targets and key performance indicators (KPIs), thereby contributing to the overall fulfilment of the Group’s sustainability ambition. Occupational safety objectives are integrated into the short-term incentive plans of all employees, including the CEO, Group Leadership Team, and business area and unit management. For the 2025 plan (payable in 2026), 10% is tied to safety performance. Targets are set annually, with payouts based on yearly results. The long-term incentive plan encompasses around 300 key employees, including the Group Leadership Team. It includes sustainability metrics on carbon reduction (10%) and gender balance (10%). The targets for the plan are set for a three-year period, and payouts in Stora Enso shares are based on the company’s performance against set targets. Shareholders at the Annual General Meeting have established a Shareholders’ Nomination Board, which is to exist until otherwise decided, and will annually prepare proposals for the Annual General Meeting’s approval concerning the number of members as well as the remuneration of the Board of Directors. The Board’s remuneration is not directly linked to the Company’s performance, but may be paid partly in Company shares, as decided by the Annual General Meeting. The compensation of the President and CEO is decided by the Board based on the evaluation and proposal by the Board’s People and Culture Committee, and the company’s Remuneration Policy. Statement on due diligence (GOV-4) Stora Enso integrates risk-based sustainability due diligence into its policies and risk management systems, covering both the Group’s own operations and the value chain. This includes identifying and prioritising human rights and environmental impacts, implementing preventive and mitigating measures, and engaging in remediation where needed. The company monitors the effectiveness of its due diligence and implements it through, for example, the following processes and tools: • Due diligence, in which the company evaluates the impact that current or potential business operations may have on local communities and the environment. • Third-party certified management systems in place at production units that apply international standards such as ISO 14001, ISO 45001, and ISO 50001. • SMETA audits focusing on social matters and working conditions. • Third-party forest management certification for the Group’s own forestry operations and suppliers, such as FSC1 and PEFC2, which also include community considerations as a prerequisite. • When necessary, organisational restructuring processes and the closure of operations are carried out in cooperation with authorities to support communities through related changes and to create opportunities for new business initiatives. • Grievance mechanisms are available for all external stakeholders, including communities close to the Group’s operations. 1 Stora Enso Communications’ FSC® trademark license number is FSC-N001919. 2 Stora Enso PEFC trademark license number is PEFC/02-44-22. Our year 2025 Our strategy Our people Governance Shareholders Report of the Board of Directors Sustainability Statement Financial Statements Appendices ≡ A s s u r e d 71 ===== SIDA 72 ===== Stora Enso’s due diligence commitment is outlined in the Sustainability Policy. Stora Enso recognises the human rights-related principles of the UN Global Compact, relevant Children’s Rights and Business Principles, and the OECD’s Guidelines for Multinational Enterprises. The core elements of Stora Enso’s due diligence are further described in the following paragraphs: Core elements of due diligence Paragraphs in the Sustainability Statement a) Embedding due diligence in governance, strategy and business model ESRS 2 GOV-2, ESRS 2 GOV-3, ESRS 2 SBM-3 b) Engaging with affected stakeholders in all key steps of the due diligence ESRS 2 GOV-2, ESRS 2 SBM-2, ESRS 2 IRO-1, ESRS MDR-P, ESRS S3 c) Identifying and assessing adverse impacts ESRS 2 IRO-1, ESRS 2 SBM-3, ESRS S3 d) Taking actions to address those adverse impacts ESRS 2 MDR-A e) Tracking the effectiveness of these efforts and communication ESRS 2 MDR-A, ESRS 2 MDR-T f) Third-party certified management systems ESRS E1-2, ESRS E4-3 Risk management and internal controls over sustainability reporting (GOV-5) Stora Enso’s internal control framework includes internal controls designed to meet the requirements on reasonable assurance for the reported sustainability data, reliability of disclosures and compliance with applicable laws, regulations, policies and guidelines. The framework is based on the principles established by the Committee of Sponsoring Organizations (COSO). The Board, supported by the Financial and Audit Committee, has the overall responsibility for setting up an effective system of internal control and risk management for sustainability reporting. The responsibility is further delegated within the organisation. The Group Internal Control is responsible for internal control governance and processes, while business areas and support and service functions are accountable for operating effective internal controls. Risk assessments have been conducted for the end-to-end sustainability reporting processes, with risks prioritised based on their impact and likelihood. The main risks identified include the accuracy, timeliness, and completeness of the reporting. To address these risks, internal controls were designed and implemented at potential points of failure or error throughout the process, from the source data to consolidation and disclosures. Implemented control activities include review and approval processes, verifications, reconciliations, IT general controls, and controls supported by IT systems. Control activities also include the policies, guidelines, procedures, and organisational structures in place to ensure that management directives are carried out and that necessary actions are taken to address risks related to the achievement of objectives concerning sustainability reporting. The effectiveness of the process for assessing risks and executing control activities is monitored continuously. The Group Internal Control oversees control design and effectiveness providing quarterly reports to management and bi-annual updates to the Financial and Audit Committee. The contributors to the sustainability reporting process from business areas and functions are informed of the findings and observations concerning the internal controls. Strategy Strategy, business model and value chain (SBM-1) Stora Enso is a global renewable materials company with an increasing focus on packaging. In 2025, the Group’s sales were EUR 9,326 (9,049) million. Stora Enso operates in the following ESRS sector groups and related sectors: Sector group: Agriculture. Sector: Forestry (AFO) Sector group: Manufacturing. Sector: Pulp, Paper & Wood products (MPW) The Group’s strategy is based on creating value in the circular economy with renewable, fiber-based materials. In 2025, key product categories included p a c k a g i n g p r o d u c t s a n d s o l u t i o n s f o r v a r i o u s i n d u s t r i e s s u c h a s food and beverage, retail, e-commerce, and industrial applications. Additional product categories included biomaterials (pulp and bio-based solutions), wood products, and building solutions. The Group’s forests serve as a reliable and long-term source of fiber for its products. Stora Enso’s key customer segments include packaging converters, food and beverage producers, brand owners and retailers, and e-commerce. Over half of the Group’s sales are directed toward consumer end uses. The Group’s main market is Europe, accounting for approximately 69% of sales. The second largest market is the Asia, contributing 16% of sales. For additional information on financial performance by segment and external sales by destination, see Financial Statements, note 2.1 Segment information. In September 2025, Stora Enso divested approximately 175,000 hectares of Swedish forest land, equivalent to about 12.4% of its total forest land holdings in Sweden. Stora Enso retains a 15% ownership of the sold company. In connection with the divestment, Stora Enso and the divested entity entered into a 15-year wood supply agreement to secure wood availability for Stora Enso’s Swedish business units. See additional information in the Financial Statements, note 6.1 Acquisitions, disposals and assets held for sale. In November 2025, the Group completed a strategic review of its Swedish forest assets as part of a stronger focus on renewable packaging and initiated preparations for the separation of the assets into a publicly-listed Swedish company, with the listing planned to be completed in 2027. In November, Stora Enso also initiated a strategic review of its Central European sawmills and building solutions operations, which is expected to be carried out in 2026. Stora Enso is a significant employer in its operating countries, employing approximately 19,000 (19,000) people at the end of 2025. The number of employees by countries is presented under ESRS S1-6. The Group’s long-term ambition is to provide regenerative products and solutions by 2050 across all markets, and product and customer categories. This means providing renewable and circular products and solutions that remove more carbon than they emit and support biodiversity restoration. Currently, the long-term ambition aligns with the significant products, markets, and customer groups within the Group. The majority of the products are designed for recycling or energy recovery at the end of their lifecycle, underscoring the commitment to the circular economy. Key sustainability matters impacting the strategy are climate change and biodiversity loss, which may adversely affect the health and resilience of forests and tree plantations, the value of forest assets, and wood prices. Conversely, strategy elements impacting sustainability matters are mainly related to the renewable, wood-based products that serve as alternatives to fossil-based materials and contribute to mitigating climate change and supporting the circular economy. The main challenge regarding sustainability matters lies in the evolving regulatory landscape and political decisions on forest resources, which could limit wood availability, increase costs, and reduce investment opportunities.

The purpose of the engagement is to: • build trust and enhance transparency, • identify market opportunities, • address concerns and areas for improvement, • recognise global trends and weak or silent signals, • promote sustainable business practices, and • advance industry standards. Stora Enso engages regularly with affected stakeholders and users of the Sustainability Statement as outlined in the table to the right. During these engagements, key stakeholders have highlighted the opportunities for Stora Enso to advance circular economy through its wood-based products, which are aligned with the Group’s business model. They have also emphasised the importance of implementing responsible business practices throughout operations and the value chain, as these are crucial for securing the long-term acceptability of the strategy. Stora Enso integrates the perspectives and rights of employees (including respect of human rights) into its business model and strategy through established cooperation structures, such as grievance channels, European Works Council, and dialogue with trade unions. These processes are detailed in ESRS S1-2. Similarly, the interests, views, and rights of value chain workers that could be materially impacted by the Group, including respect for human rights, as well as those of affected communities, inform Stora Enso’s strategy and business model. This is reflected in processes such as supplier due diligence, human rights risk assessments, grievance channels, and stakeholder dialogue (see E S R S S 2 - 2 and E S R S S 3 - 2). Outcomes from stakeholder engagement are incorporated into the annual double materiality assessment process. The Group Leadership Team and the Board of Directors receives regular updates, at least annually, regarding the perspectives and interests of affected stakeholders and users of the Sustainability Statement. These updates also include potential implications for Stora Enso’s strategy, operations, and significant sustainability-related impacts.

The impacts primarily originate from the Group’s resource- intensive business model and industrial operations, including global operations and a broad value chain. Summaries for each material topic are provided below. Detailed descriptions of the identified impacts, risks, and opportunities are presented at the beginning of each topical standard, including expected time horizons and value chain locations. Summary of material impacts, risks and opportunities resulting from materiality assessment Environment Social and governance E1 Climate change S1 Own workforce Stora Enso has a direct negative impact on climate change through greenhouse gas emissions from its own operations and indirectly through its value chain. At the same time, the Group generates positive climate impacts via forest carbon sequestration, carbon storage in wood-based products, and the substitution of fossil-based materials with renewable alternatives. In addition, Stora Enso identifies its high level of energy self-sufficiency as an opportunity. See ESRS E1 SBM-3 for further details. With a workforce of approximately 19,000 employees, Stora Enso has a direct impact on the safety and well-being of its people. Positive impacts are mainly linked to the Group’s business model and focus on its own operations. These include creating employment opportunities, promoting work-related rights, and advancing diversity, equity, and inclusion. Stora Enso has also identified an opportunity to drive competitiveness and growth through organisational restructuring, unlocking further performance potential. The identified negative impacts relate to occupational safety incidents, which occur despite preventive safety measures. The Group acknowledges its dependency on talented workforce, and recognises a risk associated with attracting and retaining talent. See ESRS S1 SBM-3 for further details. E2 Pollution S2 Workers in the value chain Stora Enso’s industrial activities generate emissions to air and water, posing risks of environmental non-compliance and significant incidents. The pollution of soil is a material topic for Stora Enso due to the environmental provision related to remediation of an existing condition caused by past operations, the most material case being in Falun, Sweden. Within Stora Enso’s own organisation, thresholds for pollution of soil are not exceeded. See ESRS E2 SBM-3 for further details. Through its supplier relationships, Stora Enso is connected to workers across the value chain. The Group recognises risks of Supplier Code of Conduct breaches and safety incidents within its upstream value chain. See ESRS S2 SBM-3 for further details. E3 Water and marine resources S3 Affected communities Stora Enso’s production sites are dependent on water, particularly in board, pulp, and paper production processes. While most sites are situated in regions with low water stress, the Group recognises water as a critical resource in meeting its environmental objectives. See ESRS E3 SBM-3 for further details. Stora Enso acknowledges that climate change may lead to controversies with local communities and non-governmental organisations concerning forest management practices, biodiversity, and land and water use. Stora Enso is primarily involved in these community- related risks through its joint operations in South America. Despite preventive and precautionary measures, safety incidents may occur at Stora Enso’s sites or forestry operations with impact on local communities. One severe incident took place in 2025. See ESRS S3 SBM-3 for further details. E4 Biodiversity and ecosystems S4 Consumers and end-users Owning forest assets enables Stora Enso to secure a reliable wood supply, reduce dependency on external suppliers, promote sustainable forestry, preserve biodiversity, and contribute to carbon sequestration. The Group has a positive impact on biodiversity through sustainable forest and biodiversity management practices in its own operations and upstream value chain. At the same time, Stora Enso recognises its negative impacts on biodiversity, such as damage to key habitats or species. Identified risks include biodiversity loss, non-compliance with harvesting regulations, and the impacts of climate change on forest ecosystems. See ESRS E4 SBM-3 for further details. Included in the double materiality assessment; does not exceed the materiality threshold. E5 Resource use and circular economy G1 Business conduct Stora Enso supports the circular economy through renewable products and solutions, with business relationships playing a vital role in enabling these impacts. At the same time, the Group recognises negative impacts linked to raw material sourcing and waste generation. The company’s strategy is aligned with circular economy principles, leveraging products to drive value. Current financial effects from material opportunities are reflected in product revenues, such as the significant investment to expand board production capacity at the Oulu site in Finland. See ESRS E5 SBM-3 for further details. Business conduct is acknowledged as a fundamental aspect of responsible global business, serving as the cornerstone of stakeholder trust and legal compliance. Stora Enso upholds high business standards, an ethical corporate culture, and a robust compliance programme, which generate positive impacts for employees and business partners. However, there are risks of non-compliance with laws, regulations, and internal policies which could lead to significant expenses and reputational damage. The Group is exposed to these risks through its own operations and business relationships. See ESRS G1 SBM-3 for further details. Our year 2025 Our strategy Our people Governance Shareholders Report of the Board of Directors Sustainability Statement Financial Statements Appendices ≡ A s s u r e d 75 ===== SIDA 76 ===== Effects of material impacts, risks and opportunities on the business model, value chain, strategy and decision-making The current effects of Stora Enso’s material impacts, risks, and opportunities on its business model, value chain, strategy, and decision- making focus on climate mitigation, given the scientific consensus on the urgency of action. The Group's emission reduction plans are aligned with the Paris Agreement and 1.5-degree scenario. In addition to reduction actions, the Group focuses on opportunities by optimising biodiversity management through new technology and driving the circular economy through product innovation and partnerships. Due to the substantial environmental footprint of forest management and resource-intensive manufacturing operations, many of the identified impacts and risks related to pollution, water, and biodiversity are predominantly addressed through responsible business practices and resource efficiency rather than significant changes to the Group’s strategy or business model. Similarly, impacts on employees and value chain workers are mainly addressed through robust employee management, HR practices, and sustainable sourcing policies. Current and anticipated financial effects The current financial effects of climate change include investments in new technology and equipment to enhance energy efficiency and reduce carbon emissions. Current financial effects of material opportunities are mostly related to revenue from renewable products, the valuation of forest assets, and investment in biological assets. For additional information, see the Consolidated income statement, Consolidated statement of financial position, and Consolidated cash flow statement in the Financial Statements. For anticipated financial effects, Stora Enso applies the phased-in provision in accordance with the ESRS 1 Appendix C for all disclosure requirements except ESRS E1-9. Resilience Stora Enso tested the resilience of its strategy and business model in 2021, when it established transition plans and introduced a new sustainability agenda centred around three focus areas: climate, biodiversity, and circularity. This was preceded by an assessment of the Group’s business model and strategic resilience in relation to future key sustainability risks and opportunities. The assessment’s time horizons were set to 2030 and 2050. The analysis indicates that, to future-proof the Group’s business model and strategy, it is essential for operations and products to actively remove carbon from the atmosphere and help mitigate biodiversity loss. Due to the rapid advances in science, technology, and regulatory frameworks, Stora Enso published a new climate resilience plan in February 2026 to guide environmental stewardship in line with global sustainability targets. For further details on the transition plans, see ESRS E1-1 and ESRS E4-1. The resilience of Stora Enso’s strategy and business model to climate change has been tested through various scenario analyses, which are explained in more detail in ESRS 2 IRO-1 (Climate change). The analyses did not identify significant risks before 2040. Changes compared to the previous reporting period Stora Enso’s reporting scope, i.e. topics and sub-topics, remain unchanged compared to the outcome of the double materiality assessment conducted in 2024, except for one sub-topic under S3 Affected communities. This exception relates to the entity-specific sub-topic on Health and safety, described in the ‘Entity-specific disclosures’ chapter below. Furthermore, some of the impacts, risks, and opportunities have been regrouped. Changes to material impacts, risks, and opportunities relate to ‘ESRS S1 Own workforce’, where Stora Enso has identified a new opportunity to drive competitiveness and unlock further performance potential through a leaner and flatter organisation. Meanwhile, the previously identified positive impact of training and development opportunities no longer meets the materiality threshold and has been excluded from the reporting scope. Entity-specific disclosures Stora Enso has prepared entity-specific disclosures for ESRS E4 Biodiversity and ecosystems and the impacts and risks related to the following sustainability matters: Direct exploitation; Endangered species and their habitat; and Impacts and dependencies on ecosystem services (see ESRS E4 SBM-3 table). These include data on biodiversity impact indicators, information on wood procurement, forest certificates, forest growth and harvesting, total standing stock and the hectares of material forest lands. For the 2025 reporting year, Stora Enso prepared an entity-specific sub- topic on Health and safety under ‘S3 Affected Communities’ due to an incident exceeding the materiality threshold (see ESRS S3 SBM-3 table). Stora Enso also reports an entity-specific metric for ESRS G1 Business Conduct and the risk related to non-compliance (see ESRS G1 SBM-3 table). This includes the total number of reported potential non-compliance cases and number of identified proven cases leading to disciplinary action and/or legal action. All other material impacts, risks, and opportunities are covered by ESRS requirements as listed in ESRS 2 IRO-2-56. Our year 2025 Our strategy Our people Governance Shareholders Report of the Board of Directors Sustainability Statement Financial Statements Appendices ≡ A s s u r e d 76 ===== SIDA 77 ===== Impact, risk, and opportunity management Description of the process to identify and assess material impacts, risks and opportunities (IRO-1) In 2024, Stora Enso conducted a double materiality assessment in accordance with the Corporate Sustainability Reporting Directive requirements. The main objective was to identify sustainability topics that have a significant impact on the Group’s business performance, risks, and opportunities (financial materiality), or reflect significant impacts on people and the environment (impact materiality). These dimensions determine the materiality of the information to be reported. Changes compared to the prior reporting period In 2025, Stora Enso revisited its double materiality assessment by reviewing material changes in business operations, significant events or incidents, legislation, and the regulatory environment. It also included reviewing latest scientific research, conducting internal stakeholder consultations, and reviewing financial risks and opportunities as part of the annual Enterprise Risk Management process. Due to the ongoing organisational restructuring and a strategic focus on performance culture, particular attention was given to topics related to own workforce through internal consultation. This led to changes in positive impacts and opportunities as outlined in ESRS 2 SBM-3. Compared to the previous year, broader stakeholder interviews were not included in the assessment. The double materiality assessment will be reviewed and updated annually according to the Corporate Sustainability Reporting Directive requirements. The process outlined below largely reflects the 2024 double materiality assessment, as no significant changes were made in 2025. Methodologies and assumptions The process adhered to the requirements outlined in the European Commission Delegated Regulation 2023/2772 on European Sustainability Reporting Standards for conducting a double materiality assessment. The assessment covered the company structure as of 31 December 2025. The underlying assumptions relied on latest scientific research, according to which climate change and biodiversity loss are accelerating. Climate change was also considered as one of the underlying drivers of financial risks. The assessment methodologies varied based on topics, but included, for example, interviews, workshops, and desktop analyses. As part of the assessment finalised in 2024, a broad representation of key internal and external stakeholders were engaged in discussions and interviews to ensure that the assessment covered all relevant impacts, risks, and opportunities. The stakeholders represented both those affected by the Group’s operations and users of the Sustainability Statement as well as other stakeholder groups such as nature (silent stakeholder), public authorities, and non-governmental organisations (NGOs). The focus of the engagement was on open interviews to gain deeper insight into the actual and potential impacts, risks, and opportunities related to Stora Enso’s business, operations, and value chain. The outcome of the engagement was consistent with Stora Enso’s strategy and business model. Identifying and assessing impacts The assessment covered the Group’s own operations and the impacts it is, or may be, associated with across its value chain. It included all business activities and geographies, and for value chain workers, affected communities, and business conduct, other factors, such as geographic locations linked to heightened risks of adverse impacts, were also considered. Overview of the process 1) Establishing an overview of the Group’s business activities, relationships, and operating context. Identifying and engaging with key stakeholders across the entire value chain, both upstream and downstream. Nature recognised as a silent stakeholder. 2) Identifying actual and potential impacts associated with sustainability matters based on stakeholder input and scientific research. 3) The established long list of impacts was compared against the full scope of European Sustainability Reporting Standards’ environmental, social, and governance matters listed in ESRS-1 Appendix A to ensure all relevant topics were included. Validation by internal subject matter experts. 4) Assessment and rating of the impacts. See below for ‘Prioritisation of impacts’. As described in ESRS 2 GOV-4, Stora Enso’s due diligence consists of multiple processes and tools. These processes were taken into account in the double materiality assessment when identifying and assessing adverse impacts. Consultation of affected stakeholders Stora Enso consulted with affected stakeholders on the topics related to own employees as part of the double materiality assessment process. For other topics, Stora Enso did not directly consult the affected stakeholders. Further information on consultation of affected stakeholders is presented below under ‘Topic-specific disclosures on identifying impacts, risks and opportunities’. Thresholds and prioritisation of impacts The different impact types were rated according to the below matrix, on a scale from 1 to 5. Stora Enso applied EFRAG’s guidance on the severity of the impact, with severity taking precedence over likelihood when assessing potential impacts to people or the environment. This means that potential impacts that are difficult to remediate were rated as more significant. Following the principle of significant impact, impacts with ‘High or critical impact to environment and people’ or ‘Very high or catastrophic impact to environment and people’ were considered material from an impact perspective. On impact materiality, scientific frameworks and global human rights principles guided the rating. For example, impacts related to planetary boundaries were considered severe. Since the Corporate Sustainability Reporting Directive does not provide guidance on setting thresholds, the approach was aligned with the EU Taxonomy, where only economic activities with a significant impact are included. Impact type Scale Scope Remediability Likelihood Actual positive impacts x x Actual negative impacts x x x Potential positive impacts x x x Potential negative impacts x x x x Our year 2025 Our strategy Our people Governance Shareholders Report of the Board of Directors Sustainability Statement Financial Statements Appendices ≡ A s s u r e d 77 ===== SIDA 78 ===== Identifying and assessing risks and opportunities Overview of the process 1) Review of the financial risks recorded in the Group’s Enterprise Risk Management (ERM) process. 2) Analysis of scientific reports, global megatrend reports, and the Group’s transition plans on climate, biodiversity, and circularity to identify relevant risks and opportunities. 3) Discussions with internal subject matter experts to validate and gain further insight into the listed risks and opportunities. 4) The established long list of risks and opportunities was compared with the full scope of European Sustainability Reporting Standards’ environmental, social, and governance matters listed in ESRS-1 Appendix A to ensure the inclusion of all relevant topics. Validation by internal subject matter experts. 5) Classification and rating of the identified risks and opportunities. See below for ‘Classification and rating of sustainability-related risks and opportunities’. When identifying opportunities, Stora Enso relied on its transition plans for key focus areas – climate change, biodiversity, and circularity – to unlock new opportunities and adapt to accelerating change. The climate transition plan was updated in 2025 and published in February 2026 (‘Stora Enso climate resilience plan’). Progress in the key focus areas is closely monitored and integrated into the double materiality assessment. Connection of impacts and dependencies with risks and opportunities Significant risks and opportunities linked to identified impacts and dependencies were considered during the materiality assessment, incorporating findings from the impact materiality phase. The outcome of the climate scenario analysis was also taken into account. Key risks include dependency on a skilled workforce and the availability of raw materials. Biodiversity loss may negatively affect the value of Stora Enso’s forest assets, increase the risk of wood supply shortages, and cause reputational damage. By further optimising its material use, the Group has an opportunity to reduce environmental impact, increase yield, and lower costs related to raw materials. Stora Enso has also identified an opportunity related to its dependency on water, based on the WRI Aqueduct Water Risk Atlas assessment. The majority of production sites are located in areas with low water stress, contributing to a stable water supply and ensuring operational efficiency. Furthermore, an opportunity has been identified for the company’s own workforce, unlocking further performance potential through a leaner, customer-centric organisation. The opportunity was recognised through internal consultation and alignment with the Group’s strategic focus, and is connected to the ongoing organisational restructuring. Classification and rating of sustainability-related risks and opportunities Sustainability-related risks were identified among all reported corporate risks, and classified into ESRS sub-sub-categories, and assigned to their corresponding value chain locations. The financial materiality scores relied on the ratings provided by the business areas in their original ERM assessment, including likelihood, magnitude, and nature of effects. Following the principle of significant impact, only the risks with a 10% or higher segment EBITDA impact were considered financially material. The segment EBITDA impact was considered instead of the Group EBITDA to focus on specific activities, business relationships, geographies, or other business area factors that contribute to a heightened risk of adverse impacts. Since sustainability is embedded into the Group’s strategy, many of the sustainability-related risks are considered high and prioritised in the ERM process due to strategic or operational importance. Opportunities were rated based on the same principles as risks. Decision-making process and integration with other management processes In 2024, the results of the double materiality assessment were discussed and reviewed with the Group’s leadership and the Board’s Sustainability and Ethics Committee and Financial and Audit Committee. The Board of Directors approved the double materiality assessment threshold and results in February 2025. The double materiality assessment update conducted in 2025 was reviewed by the Group Leadership Team, and the Board’s Sustainability and Ethics Committee and Financial and Audit Committee toward the end of the year and approved by the Board of Directors in February 2026. The process to monitor material impacts, risks, and opportunities, as well as the annual review of the double materiality assessment’s results are integrated with the Enterprise Risk Management, the Corporate Sustainability Due Diligence Directive, and the Task Force on Nature- related Financial Disclosures preparations. The process takes into account all actual significant impacts the Group had on the environment and people during the year. Stora Enso has also established a dedicated internal control for the double materiality assessment to ensure its completeness and proper approval process. The results are described in more detail in the section ESRS 2 SBM-3, and all material topics covered in this statement are listed in ESRS 2 IRO-2 'Requirements in ESRS covered by the undertaking’s sustainability statement'. Input parameters used Environmental topics • Scientific research, such as sector specific impacts identified by the UN Environment Programme World Conservation Monitoring Centre (UNEP- WCMC), the Planetary Boundaries framework by the Stockholm Resilience Center, reports from the Intergovernmental Panel on Climate Change (IPCC), the World Resources Institute (WRI) Aqueduct Water Risk Atlas tool, and the Science Based Targets for Nature Framework. • Biodiversity loss -related systemic risks to society and business considered through scientific research, such as the Living Planet 2024 report and the Dasgupta Review 2021. • Climate scenarios, described in ESRS 2 E1 IRO-1, utilised for identifying climate-related risks. • Impacts related to resource outflows and products assessed through Life Cycle Assessments and Environmental Product Declarations conducted by Stora Enso’s experts and customers, often in collaboration with academia, expert organisations, or industry associations. Social topics • Globally recognised human rights principles, such as the International Labour Organisation’s Core Convention and the International Bill of Human Rights. • Employee survey results, occupational safety performance, and insights provided by the Group’s subject matter experts. • Identification of actual and potential impacts involved interviews with the Group’s employees. • External studies, such as pay gap analyses and adequate wage benchmarks.

Our year 2025 Our strategy Our people Governance Shareholders Report of the Board of Directors Sustainability Statement Financial Statements Appendices ≡ A s s u r e d 78 ===== SIDA 79 ===== Topic-specific disclosures on identifying impacts, risks and opportunities Detailed information on identifying and assessing environmental and business conduct matters is provided below in line with the topic-specific IRO-1 requirements under ESRS. Climate change (E1: ESRS 2 IRO-1) Impacts on climate change The process to identify and assess impacts on climate change, in particular through GHG emissions, covered the Group’s own operations (Scope 1 and 2) and value chain (Scope 3) emissions as disclosed in ESRS E1-6. The screening was conducted for all production sites and material value chain emission categories. Stora Enso did not utilise other drivers for climate-related impacts in the scenario analysis although the Group recognises the Stockholm Resilience Centre’s Planetary Boundaries framework and related tipping points in its sustainability work. In addition to actual impacts, Stora Enso has estimated its potential impacts based on production forecasts. Locked-in GHG emission are described in ESRS E1-1. Climate-related scenario analysis Stora Enso has utilised multiple climate-related scenario analyses to inform the identification and assessment of physical risks, transition risks and opportunities over the short, medium, and long-term. For risks, Stora Enso defines short-term as up to one year, medium-term as two to ten years, and long-term as ten years or more. This definition aligns with Stora Enso’s enterprise risk management process. There are no critical climate- related assumptions made in the Financial Statements. The Group recognises uncertainty in the scenario analysis, as recent climate development suggests that expected time horizons for impacts in different scenarios might be shorter than anticipated. Climate-related physical risks Stora Enso has assessed climate-related hazards and evaluated how its assets and business activities may be exposed and sensitive to these risks by applying Shared Socioeconomic Pathway (SSP) scenarios, including SSP1-1.9 (Sustainability – Taking the Green Road), SSP2-4.5 (Regional Rivalry – a Rocky Road), and SSP5-8.5 (Fossil-fuelled Development – Taking the Highway). The scope covered the Group’s own operations, which are considered more exposed to potential risks, as well as its joint operations. No material physical climate change impact risks were identified before 2040. However, long-term changes over 25 to 30 years, such as altered precipitation patterns, droughts, frequent extreme weather events, and rising average temperatures, could increase the risk of forest fires and insect outbreaks, potentially affecting operations, forests, and tree plantations. More frequent extreme weather events may also disrupt production, logistics, and the supply of raw materials and energy. Climate-related transition risks Stora Enso has conducted a business impact scenario assessment for 2030, based on the global transition needed to limit temperature rise to 1.5°C in line with the Paris Agreement, using Representative Concentration Pathway (RCP) 1.9. The scope covered the Group’s own operations. The transition to a low-carbon, circular bioeconomy was found to be well aligned with Stora Enso’s strategy. However, the scenario indicated that emerging regulations and market mechanisms aimed at mitigating climate change could affect operating costs through restrictions on wood harvesting, changes in forest management, and rising emission and energy costs. Sustainable product requirements may also influence future market access, demand, and development. Due to Stora Enso’s strong presence in Europe, the mandates and regulations on existing products and services are considered almost certain in the medium term, as the European Union is implementing the EU Green Deal and related legislation. Recent legislation has focused specifically on emission reduction, deforestation, biodiversity, and the circular economy, all of which are central to Stora Enso’s strategy. Pollution (E2: ESRS 2 IRO-1) The screening of the impacts, risks, and opportunities focused on the Group’s own operations. Stora Enso consulted with environmental managers from its industrial units to determine compliance with environmental permit limits and associated emission levels. The screening process relied on measured values, calculations, or estimates from third- party assessments. Pollution in terms of air emissions and water effluents are regulated by the relevant authorities, with limits set through environmental impact assessments and permitting processes, which consider local conditions and relevant legislation. Consultations are not conducted directly with affected communities, but indirectly through these assessments and processes. Pollution-related impacts and risks are connected to Stora Enso’s business model, as the Group’s production processes generate emissions to both air and water. This poses a risk of local significant or even critical negative impacts for both the environment and people. During the past years, some of the risks have materialised into local environmental incidents. Air pollution stems from atmospheric emissions and aerosol loading due to fuel combustion, while water contamination is linked to effluents containing suspended solids, organic compounds, nutrients, and halogens from wastewater treatment. The pollution of soil is a material topic for Stora Enso due to the environmental provision related to remediation of an existing condition caused by past operations, the most material case being in Falun, Sweden. Within Stora Enso’s own organisation, thresholds for pollution of soil are not exceeded. Water and marine resources (E3: ESRS 2 IRO-1) The screening of impacts, risks, and opportunities focused on the Group’s own operations. The analysis was based on the WRI Aqueduct Water Risk Atlas, which is used to annually assess water-related risks at the Group’s own production sites, providing information on water scarcity, stress, flooding, and water quality. Marine resources were analysed as part of the assessment, but the topic did not cross the materiality threshold. Stora Enso did not consult directly with affected stakeholders as part of the process, but consultations are part of the environmental impact assessments. According to the WRI Aqueduct Water Risk Atlas tool, six of the Group’s production units operate in regions with High Baseline Water Stress: Beihai in China, Langerbrugge and Roeselare in Belgium, Wujin and Qian’an corrugated units in China, and Łódź in Poland. Biodiversity and ecosystems (E4: ESRS 2 IRO-1) The screening of actual and potential impacts included forestry sites located on the Group’s own forest land and within its upstream value chain. The assessment considered biodiversity loss-related systemic risks to society and business through scientific research, such as the Living Planet 2024 report and the Dasgupta Review 2021. Additionally, the assessment examined the tree species used for re-planting and significant incidents that negatively impact biodiversity. The impacts were identified through long-term surveillance of the ecological status of the sites and three sets of biodiversity indicators. As part of the double materiality assessment, Stora Enso did not conduct direct consultations with affected communities on sustainability assessments of shared biological resources and ecosystems, as such engagement is carried out on a regular basis. The Group’s engagement with affected communities is further detailed in ESRS S3-2 and includes also situations where a site, raw material production, or sourcing activity may have an adverse impact on biodiversity and ecosystems. Stora Enso is dependent on biodiversity and ecosystems due to wood being its primary raw material. The climate scenario analysis primarily focused on physical and systemic risks that could impact the Group’s forests. The ecosystem services considered in the assessment included tree growth and forest health. The climate scenarios and their outcome are described earlier on this page (E1: ESRS 2 IRO-1).
