While our direct exposure to developments in the Middle East remains limited, higher input and logistics costs have affected results. Arctic Paper Group's revenues for the first quarter of 2026 reached PLN 814.0 million (822.8), while EBITDA decreased to PLN 2.6 million (22.9) with an EBITDA margin of 0.3 percent (2.8). Market conditions across pulp, paper and packaging remain demanding. In response to the challenges, we continue to execute disciplined measures that are already delivering results. Capital discipline has been tightened, with capex more than halved this year. During H1 we are completing previously initiated projects, while investments in H2 remain strictly constrained. Strengthening operating cash flow through rigorous cost control and working capital optimisation remains a top priority. For the paper segment, our proactive sales strategy delivered higher volumes in the first quarter (137 000 tons vs. 125 000), contributing to sales remaining stable on PLN 573.4 million (578.8). We continue to strengthen our position: over the past three years, our share of the uncoated woodfree (UWF) paper market in Europe has increased from 10.6 percent to 13.0, while our share in coated woodfree paper rose from 6.6 percent to 8.5. We expect market consolidation to continue. EBITDA amounted to PLN 21.8 million (32.6), with a margin of 3.8 percent (5.6), negatively impacted by rising costs. To mitigate cost pressure, paper price increases of 5–7% were implemented from April, and Arctic Paper has further announced price increases of 4–8%, applicable from 1 June 2026. Our efficiency and cost reduction programme is expected to contribute approximately PLN 6 million to earnings in 2026. In the pulp segment (Rottneros), the market remained stable, while a weak USD negatively impacted prices and margins in SEK. EBITDA for the quarter was -36 MSEK, down 9 MSEK year‐on‐year. Implemented cost measures reduced the fixed cost base by around 26 MSEK compared with the same period last year. Wood prices declined further and are now 15 percent below peak levels. During the quarter, an amendment and restatement of the existing loan facility was signed, including temporary covenants valid until the end of April 2027. Focus remains on cash flow, cost efficiency and high production availability. In the packaging segment, the kraft paper volume remained relatively stable. The pulp tray production facility in Kostrzyn has entered commercial production. However, the transition from plastic to fibre‐based packaging is progressing more slowly than anticipated, which has weighed on demand. Within the power segment, the transition of the new wood pellet plant in Grycksbo into its commercial phase marks an important milestone. Already in 2026, the project will contribute positively to earnings. Pellet sales are anticipated to add approximately SEK 20 million in EBITDA, while internal energy savings from the upgraded boiler are estimated at a further SEK 20-30 million, depending on the energy price. From 2027 onwards, total annual EBITDA contribution from pellet sales is expected to increase to SEK 30-60 million, supported by higher volumes, while energy cost savings are expected to amount to SEK 30-50 million. While results are sensitive to price volatility in energy markets, the overall trend is positive. Heightened uncertainty driven by the ongoing crises in the Middle East has weakened the outlook for 2026, with no indications of a rapid market recovery. Our focus remains firmly on cost savings and measures to strengthen competitiveness, while our strong balance sheet and cost discipline provide resilience and stability in difficult times. Restoring margins and maintaining firm pricing discipline remain key priorities. ===== SIDA 11 ===== Arctic Paper Group/ Consolidated quarterly report for Q1 2026 Additional information 11 Selected items of the consolidated statement of profit and loss PLN ‘000 Q1 2026 Q4 2025 Q1 2025 Change % Q1 2026/ Q4 2025 Change % Q1 2026/ Q1 2025 Continuing operations Sales revenue 813 991 745 145 822 770 9,2 (1,1) of which: Sales of paper 573 394 517 902 578 783 10,7 (0,9) Sales of pulp 240 597 227 244 243 987 5,9 (1,4) EBIT (36 164) (59 945) (9 824) (39,7) 268,1 EBITDA 2 564 (21 257) 22 856 (112,1) (88,8) Net profit/(loss) (33 514) (75 353) (23 820) (55,5) 40,7 Net profit/(loss) for the reporting period attributable to the shareholders of the Parent Company (21 384) (42 920) (13 423) (50,2) 59,3 Sales volume (in thousand tonnes) paper 136 121 125 12,8 9,5 pulp 89 87 82 2,7 8,9 During Q1 2026, there was an increase in sales due to higher demand for paper and pulp.

As a result of the Rottneros Group signing an annex to the loan agreement, including the new terms of the loan covenants, part of the current liabilities have been re-presented as non-current liabilities.

The increase in the debt-to-equity ratio relative to the ratio calculated for Q4 2025 is the result of an increase in the Group's liabilities with a slight decrease in equity. The decrease in the equity to non-current assets ratio is primarily the result of an increase in property, plant and equipment with a slight decrease in equity. The decrease in the debt to equity ratio with interest-bearing debt compared to the ratio calculated at the end of the fourth quarter of 2025 is the result of a higher level of long-term debt. ===== SIDA 13 ===== Arctic Paper Group/ Consolidated quarterly report for Q1 2026 Additional information 13 Liquidity analysis Q1 2026 Q4 2025 Q1 2025 Change % Q1 2026/Q4 2025 Change % Q1 2026/Q1 2025 Current ratio 1,5x 1,3x 1,5x 0,2 (0,0) Quick ratio 0,8x 0,7x 0,9x 0,1 (0,1) Cash solvency ratio 0,2x 0,2x 0,3x (0,0) (0,1) DSI (days) 50,1 48,7x 65,6 1,5 (15,5) DSO (days) 47,3 44,4x 52,2 2,8 (4,9) DPO (days) 53,2 49,9x 58,0 3,3 (4,8) Operating cycle (days) 97,4 93,1x 117,8 4,3 (20,4) Cash conversion cycle (days) 44,2 43,2x 59,8 0,9 (15,6) The values of the liquidity and cash solvency ratios remain at similar levels compared with the 2025 periods. The cash conversion cycle in days in Q1 2026 increased slightly compared with Q4 2025, but decreased compared to Q1 2025. The decrease compared to Q1 2025 is due to a shortening of the rotation cycle of inventories, receivables and payables.

As a result, the Company reported a decrease in profit on sales and lower EBIT and EBITDA levels compared with the same period last year. Gross profit/(loss) and net profit/(loss) The lower financial result in Q1 2026 compared with the same period in 2025 is due to the Company achieving lower operating income resulting from lower interest and the absence of dividend income in the period. ===== SIDA 15 ===== Arctic Paper Group/ Consolidated quarterly report for Q1 2026 Additional information 15 Selected items of the separate statement of financial position PLN ‘000 31.03.2026 31.12.2025 31.03.2025 Change 31.03.2026- 31.12.2025 Change 31.03.2026- 31.03.2025 Non-current assets 1 215 215 1 190 275 1 129 685 24 940 85 530 Current assets 70 607 70 747 166 361 (140) (95 754) Total assets 1 285 822 1 261 022 1 296 046 24 800 (10 223) Equity 973 821 979 269 966 109 (5 448) 7 713 Current liabilities 255 268 247 698 302 698 7 570 (47 430) Non-current liabilities 56 733 34 055 27 239 22 678 29 494 Total equity and liabilities 1 285 822 1 261 022 1 296 046 24 800 (10 223) Non-current assets The increase in the value of non-current assets in Q1 2026 compared with Q1 2025 was due to the acquisition of a non-current asset and also due to a higher value of other financial assets (long-term intragroup loans). Current assets The decrease in current assets was due to lower cash balances in Q1 2026. Equity The decrease in equity was solely due to the negative financial result for Q1 2026. Current liabilities The increase in current liabilities in Q1 2026 was mainly due to the increased use of revolving overdrafts. Non-current liabilities The increase in non-current liabilities compared with the same period of the previous year was due to an increase in the balance of long-term bank loans.

The negative cash flow from investing activities was due to capital expenditure related to the acquisition of property, plant and equipment. Positive flows from financing activities, on the other hand, were the result of the increased use of the revolving credit facility and the receipt of further tranches of the bank loan. ===== SIDA 16 ===== Arctic Paper Group/ Consolidated quarterly report for Q1 2026 Additional information 16 Significant information and factors affecting the Arctic Paper Group’s performance and assessment of its financial position Information on market trends In Q1 2026, the Arctic Paper Group recorded an increased level of orders versus Q4 2025 by 13.9% and an increase of orders versus the equivalent period of 2025 by 9.4%. Source of data: Analysis by Arctic Paper Paper prices In Q1 2026, the average prices of high quality UWF paper decreased by 5.1% while the prices of CWF paper decreased by 4.5% versus equivalent prices of Q1 2025.

Pulp prices At the end of Q1 2026, the pulp prices were as follows: NBSK 1,653 USD/tonne and BHKP 1,280 USD/tonne. The average NBSK price in Q1 2026 was 4.5% higher than in the same period last year, while BHKP was 12.6% higher. The average pulp price in Q1 2026 was higher by 4.4% for NBSK and higher by 11.3% for BHKP as compared with Q4 2025. The average cost of pulp per ton of produced paper as calculated for the AP Group, expressed in PLN, in Q1 2026 increased by 2.1% versus Q4 2025 and decreased by 12% versus Q1 2025. The share of pulp costs in cost of paper sales in Q1 of the current year amounted to 42.2% and decreased compared to the level recorded in Q1 2025 (50%). In Q1 2026, the AP Group used pulp in the production process in the following structure: BHKP 77.5%, NBSK 15.5% and other 7%. Source of data: www.foex.fi Arctic Paper analysis. Currency exchange rates The EUR/PLN exchange rate at the end of Q1 2026 amounted to 4.2894 and was higher by 1.5% than at the end of Q4 2025 and higher by 2.5% than at the end of Q1 2025. The average exchange rate in Q1 2026 was lower by 0.1% than in Q4 2025 and amounted to 4.2352 versus 4.2383. The average exchange rate in Q1 2026 was by 0.8% higher than in Q1 2025. The EUR/SEK exchange rate at the end of March 2026 stood at 10.9423 against 10.8155 at the end of 2025 and 10.8223 at the end of Q1 2025, implying an appreciation of the EUR against the SEK by 1.1% and 1.2% respectively: ===== SIDA 17 ===== Arctic Paper Group/ Consolidated quarterly report for Q1 2026 Additional information 17 The average rate for the pair was 2.4% lower in Q1 2026 than in Q4 2025, while it was 4.8% lower compared with the same period in 2025. The changes mean depreciation of SEK vis-a-vis EUR in Q1 2026 which had an unfavourable impact on the Group’s financial results, primarily with reference to the sales revenue generated by the Swedish factories that rely on prices in EUR. At the end of Q1 2026, the USD/PLN rate recorded an increase by 3.9% versus the end of Q4 2025 and amounted to 3.7408. In Q1 2026, the mean exchange rate amounted to 3.6199 compared with 3.6432 in Q4 2025. This represents a 0.6% appreciation of the PLN against the USD compared with the previous quarter. In relation to the corresponding quarter of the previous year, the average exchange rate of the home currency against the USD strengthened by 9.3%. The USD/SEK exchange rate at the end of Q1 2026 was 9.5429, 3.5% higher than at the end of 2025. The average rate in Q1 2026 was 9.1407, 2.9% lower than the average rate in Q4 2025. The changes of the USD/SEK exchange rates in Q1 2026 favourably affected the costs incurred in USD by the Swedish Pulp Mills, in particular the costs of pulp. With regard to the Kostrzyn paper mill, the average monthly USD/PLN exchange rate weakened in relation to the corresponding rate in Q4 2025, which also translated favourably into the pulp purchase costs realised in USD by the Polish mill. At the end of March of the current year, the EUR/USD rate amounted to 1.1467 compared with 1.1736 at the end of Q4 2025 and to 1.0827 at the end of March 2025. In terms of percentage, that means a depreciation of EUR to USD by 2.3% versus Q4 2025 and an appreciation of the currency by 5.9% versus Q1 2025. In Q1 2026, the mean exchange rate of the pair amounted to 1.1702 compared with 1.1634 in Q4 2025 (+0.6%). The appreciation of SEK versus EUR has unfavourably affected the Group’s financial profit, mainly due to decreased sales revenue generated in EUR and translated into SEK. The strengthening of the PLN against the USD in Q1 2026 had a positive impact on the purchase prices of raw material at the Kostrzyn mill. The SEK strengthening against the USD, in turn, had a positive impact on the aforementioned costs at Swedish paper mills Factors influencing the financial results in the perspective of the next quarter The material factors that have an impact on the financial results over the next quarter, include:  Shaping demand for high-grade papers in Europe at a time of a tense geopolitical situation, high pulp prices, and an economic slowdown in Germany. Over the recent years there has been a major decrease of demand for fine paper in Europe (level of executed orders). Further negative developments in the market may adversely affect order levels to our Paper Mills. The accelerated digitalisation of legacy print products may have the additional effect of reducing demand for high-quality graphic papers and therefore negatively impact the Group's financial performance.  Price changes of fine paper. In particular, the possibility to maintain the prices of Arctic Paper products in local currencies in view of the declining supply/demand in Europe and in the context exchange rates fluctuations, will have a material influence on the financial results. Paper prices will play a particularly important role for the Kostrzyn mill, which is particularly strongly, and negatively, affected by falling sales volumes and prices due to the changes in the market.  Price fluctuations of raw materials, including pulp for Paper Mills and electricity for all operational entities. In particular, financial results of Paper Mills may be negatively influenced by increasing pulp prices, particularly BHKP. On the other hand, dropping NBSK pulp prices may negatively affect the financial results of Pulp Mills. Fluctuations of electricity prices in Sweden may also have a material impact on the results generated by the Group. In the future, such market changes may translate into changes of sales profitability in Paper Mills of AP Munkedals and AP Grycksbo as well as in Pulp Mills of Rottneros and Vallvik.  Changes in currency rates, in particular, the appreciation of PLN and SEK in relation to EUR and GBP, the appreciation of PLN in relation to SEK, and the depreciation of PLN and SEK in relation to USD, may have an adverse effect on the financial results. Whereby our pulp mills will benefit from the appreciation of the USD against the SEK. ===== SIDA 18 ===== Arctic Paper Group/ Consolidated quarterly report for Q1 2026 Additional information 18 Risk factors In Q1 2026, there were no material changes to the risk factors. Those were presented in detail in the annual report for 2025. Key factors affecting the Company’s performance The Group’s operating activity has been and will continue to be historically influenced by the following key factors:  macroeconomic and other economic factors;  demand growth for products based on natural fibres;  reduced demand for certain paper types;  fluctuations of paper prices;  pulp price fluctuations for Paper Mills, timber for Pulp Mills and energy prices;  fluctuations in foreign exchange rates. Macroeconomic and other economic factors We believe that a number of macro-economic and other economic factors have a material impact on the demand for high-quality paper, and they may also influence the demand for the Group’s products and the Group’s operating results. Those factors include:  GDP growth;  net income – as a metric of income and affluence of the population;  production capacity – the surplus of supply in the high quality paper segment over demand and decreasing sales margins on paper;  paper consumption;  technology development. Demand growth for products based on natural fibres The trend observed in developed societies concerning a reduction of man’s adverse impact on the environment, in particular reduction of use of disposable, plastic packaging that may not be recycled, offers new opportunities for the development of the pulp & paper sector. In many companies, work has been under way to develop new methods of packaging and production of packaging with natural materials, including pulp, so that it can be recycled. Arctic Paper is also involved in such research. In the near future, the product segment is expected to increase its percentage share in the volumes and revenue of the Arctic Paper Group. Reduced demand for certain paper types Development of new technologies, in particular in the areas of information and communication, results in decreasing demand for certain paper types – in particular, this affects newsprint and to a lesser extent – graphic papers. However, despite the increasing popularity of e-books, the volume of book paper produced and sold by Arctic Paper has been stable in the recent years, less sensitive to changing market conditions. Nevertheless, in its strategy Arctic Paper has set a direction of activity so that within several years, the segment of non-graphic papers (that is technical or packaging paper) accounts for 1/5 of its consolidated revenue. Paper prices Paper prices undergo cyclic changes and fluctuations, they depend on global changes in demand and overall macroeconomic and other economic factors such as indicated above. Prices of paper are also influenced by a number of factors related to the supply, primarily changes in production capacities at the worldwide and European level. Costs of raw materials, energy and transportation The main elements of the Group’s operating expenses include raw materials, energy and transportation. The costs of raw materials include mainly the costs of pulp for Paper Mills, timber for Pulp Mills and chemical agents used for paper and pulp ===== SIDA 19 ===== Arctic Paper Group/ Consolidated quarterly report for Q1 2026 Additional information 19 production. Our energy costs historically include mostly the costs of electricity, gas and rights to CO2 emissions. The costs of transportation include the costs of transportation services provided to the Group mainly by external entities. Considering the share of those costs in total operating expenses of the Group and the limited possibility of controlling these costs by the Group Companies, their fluctuations may have a major impact on the Group’s profitability. A part of pulp supplies to our Paper Mills is made from our own Pulp Mills. The remaining part of the pulp produced at the Pulp Mills is sold to external customers. Currency rate fluctuations The Group’s operating results are significantly influenced by currency rate fluctuations. In particular, the Group’s revenue and costs are expressed in different foreign currencies and are not matched, therefore, the appreciation of the currencies in which we incur costs towards the currencies in which we generate revenue, will have an adverse effect on the Group’s results. Our products are primarily sold to euro zone countries, Scandinavia, Poland and the UK, thus our revenue are largely denominated in EUR, GBP, SEK and PLN while revenue from the pulp mills are primarily denominated in USD. The Group’s operating expenses are primarily expressed in USD (pulp costs for Paper Mills), EUR (costs related to pulp for Paper Mills, energy, transportation, chemicals), PLN (the majority of other costs incurred by the Paper Mill in Kostrzyn nad Odrą) and SEK (the majority of other costs incurred by the Munkedal and Grycksbo Paper Mills as well as the Rottneros and Vallvik Pulp Mills). Exchange rates also have an important impact on results reported in our financial statements because of changes in exchange rates of the currencies in which we generate revenue and incur costs, and the currency in which we report our financial results (PLN). Unusual events and factors. Impact of changes in the structure of the Arctic Paper Group on the financial result Impact of the political and economic situation in the Middle East region on the Group's activities The Issuer continuously analyses the impact of the political and economic situation in the Middle East region on the Group's operations. The Group has no operations in the countries of the region and does not use logistics routes through conflict areas for the supply of raw materials or the distribution of products. The analysis conducted does not currently indicate that the conflict will have a direct material impact on the Group's operations for the foreseeable future, including in particular the availability of key raw materials or the continuity of supply chains. At the same time, the Issuer indicates that the escalation of geopolitical tensions in the Middle East region may indirectly affect the macroeconomic situation and the operating conditions of the markets in which the Group operates. In particular, potential risks include:  an increase in the volatility of energy commodity prices (including oil and gas), which may affect energy costs in Europe;  disruption to global supply chains and increased transport and insurance costs;  economic downturn and a decline in demand for the Group's products as a result of increased economic uncertainty;  exchange rate fluctuations. At the date of this report, the Issuer does not identify any significant negative impact of these factors on the Group's performance, but the situation remains dynamic and is monitored on an ongoing basis. If the risks identified materialise, they may indirectly affect the Group's operations, financial results and development prospects in the future. During Q1 2026, there were no other events or factors of an unusual nature that affected the abbreviated financial statements. ===== SIDA 20 ===== Arctic Paper Group/ Consolidated quarterly report for Q1 2026 Additional information 20 Supplementary information The Management Board position on the possibility to achieve the projected financial results published earlier The Management Board of Arctic Paper S.A. has not published the projected financial results for 2026.

Approval of the financial statements These Abbreviated Consolidated Financial Statements were approved for publication by the Management Board on 12 May 2026. 5. Accounting principles 5.1. Basis of preparation of the consolidated financial statements These abbreviated consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as endorsed by the EU (“EU IFRS”), in particular International Accounting Standard 34. These abbreviated consolidated financial statements have been presented in Polish zloty (“PLN”) and all values are rounded to the nearest thousand (PLN ‘000) except as stated otherwise. ===== SIDA 38 ===== Arctic Paper Group/ Consolidated quarterly report for Q1 2026 38 Additional explanatory notes These Abbreviated Consolidated Financial Statements have been prepared based on the assumption that the Group companies will continue as a going concern in the foreseeable future. The abbreviated consolidated financial statements do not include all the information and disclosures required in the annual consolidated financial statements and should be read in conjunction with the Group’s annual consolidated financial statements for the year ended on 31 December 2025. 5.2. Changes in applied accounting policies The accounting policies applied in the preparation of the financial statements are consistent with those applied in the preparation of the Company's financial statements for the year ended 31 December 2025. The Company did not decide to adopt earlier other standards, interpretations or amendments that were issued but are not yet effective for periods commencing on 1 January 2025. 5.3. New and amended standards and interpretations applied New standards and amendments to existing standards that come into force in 2025 have been applied in these financial statements: a) Amendments to IAS 21 “The Effects of Changes in Foreign Exchange Rates” In August 2023 the Board published amendments to IAS 21 “The Effects of Changes in Foreign Exchange Rates”. The changes introduced are intended to make it easier for entities to determine whether a currency is convertible into another currency and to estimate the spot exchange rate when a currency is not convertible. In addition, the amendments to the standard require additional disclosures in the case of non-convertibility on how the alternative exchange rate was determined. These changes have no impact on these financial statements. 5.4. New standards and interpretations that have been published and are not yet effective In these financial statements, the Group has not decided to early apply the following published standards, interpretations or amendments to existing standards before their effective date: a) Changes in the classification and measurement of financial instruments – Amendments to IFRS 9 and IFRS 7 IFRS In May 2024, the IASB published amendments to IFRS 9 and IFRS 7 aimed at: — clarify the recognition and derecognition dates for certain financial assets and liabilities, with an exemption for certain financial liabilities settled through electronic funds transfer. clarify and add further guidance on assessing whether a financial asset meets the SPPI criteria; — add new disclosures for certain instruments whose contractual terms may alter cash flows; and — update disclosures on equity instruments measured at fair value through other comprehensive income (FVOCI). The published amendments are effective for financial statements for periods beginning on or after 1 January 2026. b) Annual Improvements to IFRS “Annual Improvements to IFRS” introduces changes to the standards: IFRS 1 “First-time Adoption of International Financial Reporting Standards”, IFRS 7 “Financial Instruments: Disclosures”, IFRS 9 “Financial Instruments”, IFRS 10 “Consolidated Financial Statements” and IAS 7 “Statement of Cash Flows”. The amendments provide clarifications and clarify the standards’ guidance on recognition and measurement. The published amendments are effective for financial statements for periods beginning on or after 1 January 2026. c) Contracts relating to electricity dependent on natural factors: Amendments to IFRS 9 and IFRS 7 ===== SIDA 39 ===== Arctic Paper Group/ Consolidated quarterly report for Q1 2026 39 Additional explanatory notes In December 2024, the Board published the amendments to help companies better recognise the financial effects of contracts relating to natural dependent electricity, which are often in the form of power purchase agreements (PPAs). The current guidance may not fully capture the impact of these contracts on the company's performance. To enable companies to better reflect these contracts in their financial statements, the Board has amended IFRS 9 Financial Instruments and IFRS 7 Financial Instruments: disclosures. These changes include: clarifying the application of the “own use” criterion; — allowing hedge accounting where these contracts are used as hedging instruments; — adding new disclosures to enable stakeholders to understand the impact of these contracts on financial performance and cash flows. The published amendments are effective for financial statements for periods beginning on or after 1 January 2026. d) IFRS 18 “Presentation and Disclosures in Financial Statements” In April 2024, the Board published the new standard IFRS 18 “Presentation and Disclosures in Financial Statements”. The standard is intended to replace IAS 1 – Presentation of Financial Statements and will be effective from 1 January 2027. The changes to the superseded standard mainly concern three issues: the statement of profit or loss, required disclosures about performance measures and issues related to the aggregation and disaggregation of information contained in financial statements. The published standard will be effective for financial statements for periods beginning on or after 1 January 2027. As at the date of these consolidated financial statements, the modifications have not yet been approved by the European Union. e) IFRS 19 “Subsidiaries Without Public Accountability: Disclosure of Information” In May 2024, the Board issued a new accounting standard, IFRS 19, which can be adopted by certain subsidiaries applying IFRS accounting standards to improve the effectiveness of disclosures in their financial statements. The new standard introduces simplified and limited disclosure requirements. As a result, the qualifying subsidiary applies the requirements of other IFRS accounting standards with the exception of the disclosure requirements and instead applies the limited disclosure requirements of IFRS 19. Eligible subsidiaries are entities that are not subject to so-called public accountability as defined in the new standard. In addition, IFRS 19 requires the ultimate or intermediate parent of the entity to prepare publicly available consolidated financial statements in accordance with IFRS Accounting Standards. Eligible entities may choose to apply the guidance of the new IFRS 19 for financial statements prepared for periods beginning on or after 1 January 2027. At the date of these financial statements, these amendments have not yet been approved by the European Union. f) IFRS 19 “Subsidiaries Without Public Accountability: Disclosure of Information” In August 2025 the Board published amendments to IFRS 19 to support qualifying subsidiaries by reducing the disclosure requirements for standards and amendments to standards issued between February 2021 and May 2024.The amendments include the following standards: IFRS 18: Presentation and Disclosures in Financial Statements; Amendments to IAS 7 and IFRS 7 – Supplier Financing Arrangements; Amendments to IAS 12 – International Tax Reform; Amendments to IAS 21 – Non-convertibility of Currencies; Amendments to IFRS 9 and IFRS 7 – Classification and Measurement of Financial Instruments. With these changes, IFRS 19 incorporates all updates to IFRS standards that will be effective from 1 January 2027, the effective date of IFRS 19. At the date of these financial statements, these amendments have not yet been approved by the European Union ===== SIDA 40 ===== Arctic Paper Group/ Consolidated quarterly report for Q1 2026 40 Additional explanatory notes g) Amendments to IAS 21 “The effects of changes in foreign exchange rates – translation into the presentation currency in a hyperinflationary environment”. The International Accounting Standards Board announced in November 2025 amendments that clarify how companies should convert financial statements from a non-hyperinflationary currency to a hyperinflationary currency. These narrow scope changes aim to improve the usability of the information obtained in a cost-effective manner. Developed in response to stakeholder feedback, the changes are intended to reduce diversity of practice and provide a clearer basis for reporting in a hyperinflationary currency. The amendments to IAS 21 “The Effects of Changes in Foreign Exchange Rates” will be effective for annual periods beginning 1 January 2027. The Company may elect to apply them early. At the date of these financial statements, these amendments have not yet been approved by the European Union. h) IFRS 14 “Regulatory Accruals and deferred income” This standard allows entities that prepare their financial statements in accordance with IFRS for the first time (on or after 1 January 2016) to recognise amounts arising from price-regulated activities in accordance with existing accounting policies. To improve comparability, with entities that already apply IFRS and do not report such amounts, under published IFRS 14, amounts arising from regulated price activities should be presented as a separate line item in both the statement of financial position and the statement of profit or loss and statement of other comprehensive income. By a decision of the European Union, IFRS 14 will not be endorsed. i) Amendments to IFRS 10 and IAS 28 on the sale or contribution of assets between an investor and its associates or joint ventures The amendments resolve the current inconsistency between IFRS 10 and IAS 28. The accounting treatment depends on whether the non-monetary assets sold or contributed to the associate or joint venture constitute a “business”. Where non-monetary assets constitute a “business”, the investor shows a full profit or loss on the transaction. If the assets do not meet the definition of a business, the investor recognises a gain or loss only to the extent of the interests held by other investors. The amendments were published on 11 September 2014. At the date of these consolidated financial statements, approval of this amendment is deferred by the European Union. At the date of approval of these financial statements for publication, the Company does not plan to implement IFRS 18 early and is in the process of analysing the impact of this standard on the financial statements. The implementation of the standard will change the layout of the statement of profit and loss and reclassify certain items to financing or investing activities. 5.5. Foreign currency translation Transactions denominated in currencies other than the functional currency of the entity are translated into the presentation currency at the foreign exchange rate prevailing on the transaction date. On the balance sheet date, monetary assets and liabilities expressed in currencies other than the functional currency of the entity are translated into the functional currency using the mean foreign exchange rate prevailing for the presentation currency as at the end of the reporting period. Foreign exchange differences from translation are recognised under finance income or finance costs or are capitalised as cost of assets, as defined in the accounting policies. Non-monetary foreign currency assets and liabilities recognised at historical cost are translated at the historical foreign currency rates prevailing on the transaction date. Non-monetary assets and liabilities denominated in a currency other than the functional currency, recognised at fair value are translated into the functional currency using the rate of exchange prevailing on the date of revaluation to fair value. ===== SIDA 41 ===== Arctic Paper Group/ Consolidated quarterly report for Q1 2026 41 Additional explanatory notes The functional currencies of the foreign subsidiaries are EUR, SEK, DKK, NOK, GBP and CHF. As on the balance sheet date, the assets and liabilities of those subsidiaries are translated into the presentation currency of the Group (PLN) at the rate of exchange prevailing on the balance sheet date and their statements of profit or loss are translated using the average weighted exchange rates for the relevant reporting period. The foreign exchange differences on translation are recognised in other comprehensive income and cumulated in a separate equity item. On disposal of a foreign operation, the cumulative amount of the deferred exchange differences recognised in equity and relating to that particular foreign operation shall be reclassified to profit or loss. Foreign exchange differences on loans treated in compliance with IAS 21 as investments in subsidiaries are recognised in the consolidated financial statements in other comprehensive income. The following exchange rates were used for book valuation purposes: As at 31 March 2026 As at 31 December 2025 USD 3,7408 3,8643 EUR 4,2894 4,1839 SEK 0,3920 0,3866 DKK 0,5740 0,5608 NOK 0,3824 0,3676 GBP 4,9426 5,0020 CHF 4,6764 4,3875 Mean currency exchange rates for the reporting periods are as follows: 01.01 – 31.03.2026 01.01 – 31.03.2025 USD 3,6199 3,9931 EUR 4,2352 4,2013 SEK 0,3960 0,3741 DKK 0,5669 0,5632 NOK 0,3723 0,3606 GBP 4,8777 5,0268 CHF 4,6210 4,4418 6. Seasonality The Group’s activities are not of seasonal or cyclical nature. Therefore, the results presented by the Group do not change significantly during the year or a cycle. 7. Operational segments Operational segments cover continuing activities. The Group’s principal activity is the production of paper and pulp. The paper production business includes the financial results of three paper mills, among others: — Arctic Paper Kostrzyn S.A. (Poland) – produces high-quality uncoated graph paper under the Amber brand; — Arctic Paper Munkedals AB (Sweden) – produces high quality uncoated graphic paper under the Munken brand; — Arctic Paper Grycksbo (Sweden) – production of coated wood-free paper under the brands of G-Print and Arctic. The pulp business is presented as the “Pulp” segment and includes, among other things, two pulp plants: ===== SIDA 42 ===== Arctic Paper Group/ Consolidated quarterly report for Q1 2026 42 Additional explanatory notes — Rottneros mill (Sweden) – produces mechanical fibre pulp: chemi-thermo mechanical pulp (CTMP), production level of about 160,000 tonnes annually; — the pulp mill in Vallvik (Sweden) produces two types of long-fibre sulphate pulp: fully bleached sulphate pulp and unbleached sulphate pulp. The most of Vallvik pulp mill production is known as NBSK pulp. Production level of about 240,000 tonnes annually. The Group identifies the following business segments: — Paper – this segment includes uncoated and coated papers. Uncoated paper – paper for printing or other graphic purposes, including wood-free and wood-containing paper. Uncoated wood-free paper may be produced from various types of pulp, with different filler content, and can undergo various finishing processes, such as surface sizing and calendering. Two main categories of this type of paper are graphic paper (used for example for printing books and catalogues) and office papers (for instance, photocopy paper); however, the Group currently does not produce office paper. Uncoated wood paper from mechanical pulp intended for printing or other graphic purposes. That type of paper is used to print magazines with rotogravure and offset techniques. The Group’s products in this segment are usually used for printing paperbacks, Coated paper – wood-free paper for printing or other graphic purposes, one-side or two-side coated with mixtures containing mineral pigments, such as china clay, calcium carbonate, etc. The coating process can involve different methods, both online and offline, and can be supplemented by super-calendering to ensure a smooth surface. Coating improves the quality of printed photos and illustrations. — Pulp – fully bleached sulphate pulp and unbleached sulphate pulp which is used mainly for the production of printing and writing papers, cardboard, toilet paper and white packaging paper as well as chemi-thermo mechanical pulp (CTMP), which is mainly used in the production of printing and writing paper. The exclusions include the exclusions of turnover and settlements between segments and the results of operations of Arctic Paper S.A. and Arctic Paper Finance AB. The split of operating segments into the paper and pulp is due to the following factors: — Demand for products and their supply as well as the prices of products sold in the market are affected by operational factors characteristic for each segment, such as e.g. the production capacity level in the paper and pulp segment. — The key operating parameters such as inflow of orders or the level of production costs are determined by the factors that are similar for each paper and pulp segment. — The products manufactured at the Paper Mills operated by the Group may (with certain restrictions) be allocated to production in other entities within the same paper segment, which to a certain extent distorts the financial results generated by each Paper Mill. — The results of the Arctic Paper Group are under the pressure of global market trends with respect to the prices of paper and pulp, and to a lesser extent are subject to the specific conditions of the production entities. Every month, on the basis of internal reports received from companies (apart from companies of the Rottneros Group), the results in each operating segment are analysed by the management of the Group. The financial results of companies in the Rottneros Groups are analysed on the basis of quarterly financial results published on the websites of Rottneros AB. The operating results are measured primarily on the basis of EBITDA calculated by adding depreciation/amortisation and impairment loss on property, plant and equipment and intangible assets to operating profit/(loss), in each case in compliance with EU IFRS. In accordance with EU IFRS, EBITDA is not a metric of operating profit/(loss), operational results or liquidity. EBITDA is a metric that the Management Board uses to manage the operations.
