Basis for the interim condensed consolidated financial statements preparation These interim condensed consolidated financial statements (‘the statements’) have been prepared in accordance with the International Accounting Standard No. 34 Interim Financial Reporting, as endorsed by the EU (‘IAS 34’). These interim condensed consolidated financial statements have been prepared in Polish zlotys (‘PLN’) and all amounts, unless stated otherwise, are presented in PLN millions. These interim condensed consolidated financial statements were approved for publication on 26 October 2026.

Consolidated quarterly report for Q3 2026 (PLN millions) 15 The financial statements have been prepared on a going concern basis. According to the Management Board, as at the date of preparation of these statements there are no uncertainties relating to the Group’s ability to continue as a going concern in the foreseeable future covering a period of at least 12 months from the reporting date. In making this assessment, the Management Board considered in particular the impact of climate -related issues and geopolitical factors, including the war in Ukraine and the situation in the Middle East. The analyses carried out were based on a number of assumptions and factors that may change in the future. 3.1. Impact of climate-related issues on the Group operations An analysis of the impact of climate -related issues on the Group operations is presented in Note 5.4 of the consolidated financial statements of the Group for 2025, published on 26 March 2026. There were no new material circumstances between the date of pu blication of those financial statements and the date of publication of these interim condensed consolidated financial statements that could affect the findings of that analysis. In the opinion of the Management Board, there were no events that would requir e an update to the disclosures on the impact of climate-related issues on the Group operations. 3.2. Impact of the war in Ukraine on the Group operations A description of the impact of the war in Ukraine on the Group operations is presented in detail in Note 5.2 of the consolidated financial statements of Grupa Kęty for 2025, published on 26 March 2026. After that date, there were no new factors or events having a material impact on the Group operations in the Ukrainian market. 3.3. Impact of the war in the Middle East Military operations involving Israel, the United States and Iran in the Persian Gulf region, which began on 28 February 2026, are causing disruptions to global supply chains, particularly on transport routes vital to industrial raw materials markets. As re gards the Capital Group operations, this primarily concerns aluminium and plastic granules, which are used as key raw materials in production processes. The Group’s dependence on direct supplies of raw materials from the conflict -affected region remains limited. However, disruptions in logistics and increased geopolitical risks may lead to significant volatility in the prices of aluminium and granules, as well as greater uncertainty regarding the long-term availability of these raw materials. As at the date of preparation of these statements, the Group has secured raw materials for approximately three months, while continuing to monitor the market in order to possibly extend the hedging horizon and further diversify the Group’s supply sources. Despite the ongoing conflict, the situation in the period is not much different from the standard one, thanks to the actions taken. Considering the current level of inventories, existing contracts and the absence of significant disruptions in the current operations, the Management Board is of an opinion that there are no material uncertainties relating to the Group’s going concern assumption in the financial statements, given the current geopolitical situation. 4. Significant accounting policies The accounting policies applied in preparing these interim condensed consolidated financial statements are consistent with the ones applied in preparing the consolidated financial statements of the Group for the year ended on 31 December 2025. These interim condensed consolidated financial statements do not cover all information and disclosures required to be made in the consolidated annual financial statements, and should therefore be read in conjunction with the consolidated financial statements of the Group for the year ended on 31 December 2025, published on 26 March 2026.

Consolidated quarterly report for Q3 2026 (PLN millions) 16 The following amendments to the standards became effective on 1 January 2026: • Amendments to IFRS 9 and IFRS 7 concerning the classification and measurement of financial instruments in the following scopes: - classification of financial assets with ESG -linked features: The improvement to IFRS 9 concerns mainl y loans granted and will not have any impact on the consolidated financial statements of the Group, as the Group does not have any loans with ESG-linked features; - rules for the derecognition of a financial liability settled through electronic transfer. This amendment will not have any impact on the consolidated financial statements of the Group, as the Group does not accept such payments; - an amendment to IFRS 7, para. 11A, concerning disclosure requirements for equity instruments measured at fair value through other comprehensive income. The Group does not hold such instruments. • Amendments to IFRS 9 and IFRS 7 concerning contracts referencing nature -dependent electricity The amendments concern contracts that expose an entity (purchaser of electricity) to variability because the source of electricity generation depends on uncontrollable natural conditions (e.g. wind or sunshine). As at the date of preparation of these conde nsed consolidated financial statements, the Group has Power Purchase Agreements (PPAs) for the purchase of nature-dependent electricity. The Group uses all the energy supplied from these sources for its own needs, as the volume purchased represents an imma terial part of the Group’s requirements and, therefore, the Group does not resell it. Pursuant to IFRS 9, para. 2.4, the Group treats these agreements as not covered by this standard. • Annual improvements to IFRS standards – volume 11 The amendments introduced to the standards under this improvement cycle have no material impact on the consolidated financial statements of the Group. • Expected impact of the adoption of IFRS 18 Presentation and Disclosure in Financial Statements IFRS 18 Presentation and Disclosure in Financial Statements was published by the International Accounting Standards Board (IASB) in April 2024 and will apply to reporting periods beginning on or after 1 January 2027. The standard will replace the current I AS 1 Presentation of Financial Statements. At the same time, amendments to other standards were published, in particular IAS 7, IAS 8, IAS 33, IAS 34 and IFRS 7, which will become effective on the same date. The new regulations aim to improve the comparability of financial statements by standardising the structure of the statement of profit or loss, clarifying the rules for the presentation of financial information and introducing additional disclosure requirements regarding the performance measures used by management. The most significant changes resulting from IFRS 18 include: • introduction of a mandatory classification of income and expenses into specific categories of activity – this classification depends, among others, on an assessment of whether the entity carries out one of the so-called specified main business activities, i.e. investing in assets or providing financing to customers, • presentation of new mandatory subtotals in the statement of profit or loss, in particular operating profit and profit before financing and income taxes, • clarification of the rules for the presentation and disclosure of operating expenses, • extension of the requirements for the aggregation and disaggregation of financial information, • clarification of the rules for the placement of information – whether in the primary financial statements or in the notes to the financial statements, • introduction of new disclosures on management-defined performance measures (MPMs). Besides, the standard introduces detailed guidance on the classification of exchange gains and losses, derivatives, hedging instruments and selected hybrid instruments.

Consolidated quarterly report for Q3 2026 (PLN millions) 17 Implementation status As at the date of approval of these condensed consolidated financial statements, the Group had completed its assessment of the standard’s impact on the presentation of its financial performance and the statement of cash flows. IFRS 18 will be applied retrospectively in accordance with the requirements of IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors. The Group does not expect the adoption of IFRS 18 to have an impact on net profit, comprehensive income or equity. Expected changes will relate mainly to the presentation, aggregation and disclosure of financial information. Consolidated statement of profit or loss Following the assessment, the Group has concluded that it does not carry out any of the specified main business activities within the meaning of IFRS 18. Consequently, certain items of income and expenses relating to the return on assets will be presented under the investing category. At the same time, the Group will classify income and expenses arising both from financial liabilities incurred to finance its operations, and from other liabilities falling under specific regulations of IFRS 18, under the financing category. This applies in particular to: • interest expense on loans and borrowings, • interest expense on leases, • net interest expense on liabilities under defined benefit plans, • effects of discounting and changes in the value of provisions due to the passage of time. Should the above classification be adopted, the following figures would be presented for the period from 1 January to 30 September 2026: • operating profit higher by PLN 2 million than that presented under the current classification (due to exchange differences on receivables and payables); • profit before finance costs and income tax lower by PLN 1 million (due to exchange differences on cash); • finance costs lower by PLN 1 million. Consequently, profit before tax would remain unchanged. As regards the presentation of operating expenses, the Group has assessed the requirements of IFRS 18 and concluded that the current classification by nature best reflects the nature of its business operations. Consequently, no changes are anticipated to the basic method of presenting operating expenses. Consolidated statement of cash flows The amendments to IAS 7 will result in a change to the starting point for presenting cash flow from operating activities prepared using the indirect method. Under the new requirements, cash flow from operating activities would start with operating profit (in accordance with IFRS 18) of PLN 783 million, and not, as is currently the case, with profit before tax of PLN 736 million presented under the current classification. Consequently, the scope of non -cash adjustments disclosed under the operating section of the statement of cash flows would be modified accordingly, including, among others, exchange differences allocated to investing and financing activities. Management-defined performance measures The Group has assessed the performance measures used in communications with capital market participants and for internal management purposes. As at the date of this report, the Group has not identified any Management -defined Performance Measures as defined in IFRS 18, which would require specific disclosures.

Consolidated quarterly report for Q3 2026 (PLN millions) 18 Impact of the international tax system reform – Pillar 2 of BEPS 2.0 Project • The Act of 6 November 2024 on top -up taxation of constituent entities of multinational and domestic groups (‘the Act’) transposed into national law the regulations of Council Directive (EU) 2022/2523 of 14 December 2022 on ensuring a global minimum level o f taxation for multinational enterprise groups and large -scale domestic groups in the European Union. The adoption of the Act marks the implementation of guidelines of the so-called Pillar 2 of BEPS 2.0 Project, which introduces a general framework for a g lobal minimum tax approved as part of the work at the OECD forum (‘OECD Framework’). • The Polish legislation came into force on 1 January 2025, with an option of voluntary application from 1 January 2024 (for global top-up tax and domestic top-up tax). Grupa Kęty S.A. (‘the Company’) did not make use of the option of voluntary application of the above regulations from 1 January 2024. • By virtue of the Act, the Company meets the criteria to be classified as a so -called multinational enterprise (MNE) and is therefore required to report the level of taxation of its subsidiaries in individual jurisdictions. As at the date of publication of these condensed consolidated financial statements of the Group, the global top-up tax and domestic top -up tax regulations were implemented in most of the jurisdictions in which the Group currently operates, except for Ukraine and the US. • While the Directive regulations have been binding since 2024, the OECD Framework provides for a transition period, postponing the duties in that regard for further four years. Based on an analysis of the underlying transition period regulations, the Group is of an opinion that it will be able to make use of them in relation to most of the jurisdictions in which it operates. At the same time, according to current estimates, the Group believes that the likelihood of having to pay a top-up tax in any jurisdiction is low. In accordance with the requirements of IAS 12, para. 88A, the Group does not recognise deferred tax assets and liabilities relating to Pillar 2 income taxes, nor does it disclose information on these assets and liabilities. Based on the results of the anal yses carried out, no amounts resulting from the reform of the international tax system – Pillar 2 – have been recognised in these condensed consolidated financial statements. • For 2025, the Group did not have any top -up income tax payables. The Group may be required to pay top -up income tax for the years 2026 and 2027, if the conditions for maintaining the temporary safe harbour exemption are not met for that period and if, in a ny of the jurisdictions in which the Group subsidiaries operate, the effective tax rate (calculated in accordance with BEPS regulations) is below 15%. In the years following 2027, the Group may be obliged to pay top-up income tax if in any of the jurisdictions where the Group operates, the effective tax rate calculated in accordance with BEPS regulations is lower than 15%. Since the Group entities are, as a rule, located in high -tax jurisdictions, the likelihood of having to pay top -up tax in the future is – to the best of the current knowledge and judgement of the Group – assessed as low. 5. Areas of estimation The main accounting estimates made are presented in the respective explanatory notes to the interim condensed consolidated financial statements: • estimates concerning recognition and measurement of lease contracts are presented in Note 18; • estimates concerning write-downs of inventories are presented in Note 15; • estimates and assumptions concerning write-downs of receivables are presented in Note 14; • estimates concerning write-downs of goodwill are presented in Note 13; • estimates concerning provisions and accruals are presented in Note 16; • estimates concerning deferred tax assets/liabilities are presented in Note 11; • estimates concerning the measurement of share-based payments are presented in Note 19;

Page 20

Consolidated quarterly report for Q3 2026 (PLN millions) 19 • estimates concerning investment properties are presented in Note 37 of the consolidated financial statements for 2025; • estimates concerning measurement of liabilities on account of production technology are presented in Notes 10.8 and 28 of the consolidated financial statements for 2025; • estimates concerning impairment of property, plant and equipment are presented in Note 12.2; • estimates concerning impairment of assets are presented in Notes 13.7 and 13.8 of the consolidated financial statements for 2025; • estimates concerning control or influence over other entities are presented in Note 10.1 of the consolidated financial statements for 2025; • estimates concerning depreciation and amortisation rates are presented in Notes 10.4 and 10.8 of the consolidated financial statements for 2025. A detailed description of the assumptions made in the particular areas of estimation is provided in the consolidated financial statements for 2025. In the 9-month period of 2026, there were no major differences in the assumptions and estimates compared with 2025. Except the ones described above, there were no other changes in estimates in the reporting period. 6. Seasonality of operations The Capital Group operates in four operating segments, offering a broad portfolio of products aimed at a wide range of industries across various sectors of the economy. Nearly half of the sales are directed to foreign markets. The development and diversifi cation of products in the recent years have contributed to reducing the impact of seasonality on the Group operations. Seasonality of operations is not material at the FPS. Whereas at the EPS and the ASS higher demand for products is typically observed in the second and third quarters compared with the first and fourth quarters. This is mainly due to weather conditions and production cycles characteristic of the construction and industrial sectors, which account for a significant proportion of the Group products. In the opinion of the Management Board, the seasonality observed is not material within the meaning of IAS 34, para. 21. 7. Business segments The Group operations are organised and managed on the basis of operating segments, which are defined according to the type of products and services offered. Each segment is a business unit or a group of business units, supplying various products and serving various markets. The division into segments complies with the management reporting structure, used by the Management Board when making operating and strategic decisions. Transactions between segments are accounted for as if they were made between unrelated parties, that is using current market prices. The operating segments of the Group are identical with the reporting segments presented in these interim condensed consolidated financial statements. The Capital Group operations are carried out and reported broken down into: • Extruded Products Segment (EPS); • Sun-shading Systems Segment (SSS); • Architectural Systems Segment (ASS); • Flexible Packaging Segment (FPS); • Other, including the so-called Centrum Grupy Kęty S.A., responsible for the management of such areas as Finance, Reporting, IT, PR, Investor Relations, Risk and Compliance Management, Internal Audit, Development and Capital Investments, HR, as well as Dekr et Centrum Rachunkowe sp. z o.o., which provides accounting, HR, and payroll services to the Group companies. The assignment of the particular Group companies to the operating segments is presented in Note 2.

Cash and cash equivalents Cash at bank bears interest at variable rates, which are driven by the interest rates on overnight bank deposits. Short-term term deposits are made for various periods – usually from one day to several days – depending on the Group’s current cash requirements. They bear interest at rates set individually for each deposit term. The fair value of cash and cash equivalents is presented in the table below. 30.09.2026 31.12.2025 Bank deposits (current accounts) and short-term deposits 74 64 Total 74 64 As at 30 September 2026, the Group had restricted cash in its VAT accounts amounting to PLN 11 million (31 December 2025: PLN 13 million). The cash may be used only for the purpose of output VAT, CIT, PIT and ZUS [social security] payments to authorities or as VAT payments to the Company suppliers. As at 30 September 2026, the Group had undrawn credit limits amounting to PLN 715 million, with regard to which all conditions precedent had been complied with (31 December 2025: PLN 564 million). In that amount, the available credit limits with maturity dates exceeding 12 months represented PLN 281 million (31 December 2025: PLN 232 million). Besides, the Group made a loan agreement for the equivalent of PLN 2 billion to finance the acquisition of the Metra Group (see Note 24). As at 30 September 2026, the loan had not been drawn down. 10. Dividend payments made and proposed Pursuant to the resolution of the Annual General Meeting of 18 June 2026, Grupa Kęty S.A. allocated PLN 483 million from the 2025 profit as a dividend to the Shareholders of the Company, which represents PLN 48.97 per share, calculated based on the number of the Company shares as at dividend record day (9,858,272 shares). 19 August 2026 was set as dividend record day, whereas dividend payment date was set for 3 September 2026 – the instalment paid (the amount of PLN 161 million, which represents PLN 16.33 per share) and 4 November 2026 (the amount of PLN 322 million, which represents PLN 32.64 per share). In 2025, the parent company paid dividend in the amount of PLN 545 million, which represents PLN 55.50 per share. 11.

Current receivables 30.09.2026 31.12.2025 Net receivables: 1,037 750 Trade receivables 991 710 Deposits on account of aluminium price hedging transactions 3 4 Other 6 4 Total net financial receivables (under IFRS 7) 1,000 718 State receivables (except for income tax) 11 12 Advance payments (trade-related) to suppliers 13 7 Prepaid expenses 13 13 Total net non-financial receivables 37 32 In the 9-month period of 2026 and the 9 -month period of 2025, a change in write-downs of financial receivables amounted to less than PLN 1 million. The write-downs recognised/reversed are presented in a separate item of the statement of profit or loss – ‘Write- downs of financial assets – IFRS 9’. Trade receivables do not bear interest and have payment terms from 14 to 120 days. There is no concentration of receivables from one contractor which would exceed 10%. The Group has implemented a policy of selling solely to verified customers and insures receivables with specialised companies. Consequently, according to the management’s opinion, there is no additional credit risk exceeding the level established by the wr ite-down. The fair value of receivables is close to their book value. The reasons for material changes in receivables as at 30 September 2026 compared with 31 December 2025 are presented in Note 22. 15.

Equity securities – employee share plan In the 9-month period of 2026, within the exercise of the second and third tranche of the 2020 plan, the key staff of the Group took up 22,624 shares of Grupa Kęty S.A., on the conditions determined in the plan. Presently, Grupa Kęty S.A. runs a share option plan of Grupa Kęty S.A. of 2023. The plan is directed to key management staff of the Capital Group. In the 9-month period of 2026, there were not made any changes in estimates or assumptions in relation to those adopted and published in the consolidated financial statements for 2025. Detailed information on the share option plan is provided in Note 21.1 of the consolidated financial statements for 2025. Besides, on 18 June 2026, the Annual General Meeting approved another incentive plan. The aim of the plan, similarly to previous ones, is to build the value of Grupa Kęty by improving financial performance and achieving above-average growth in the value of the Company shares. Key assumptions: The plan will cover members of the Management Board and the key management staff of the Group (up to 149 people). A total of up to 150,000 new shares may be granted, divided into three equal tranches of 50,000 shares each. The options will be granted between 2026 and 2028, and exercised between 2029 and 2034. To be eligible to participate, an option holder must remain in employment or under another legal relationship for at least three years from the date the options are granted. Share acquisition conditions: In order to exercise an option, specific targets must be achieved: • 20% of the tranche – total shareholder return (TSR) exceeding the WIG index by at least 5 p.p.; • 20% of the tranche – TSR exceeding the WIG index by at least 10 p.p.; • 60% of the tranche – achievement of specified levels of net earnings per share (EPS): o PLN 94.70 for 2028, o PLN 96.84 for 2029, o PLN 98.65 for 2030. Where EPS is between 90% and 100% of the target, the number of warrants granted will increase proportionally from zero to the maximum number. Share subscription price: The issue price will be equal to the average stock exchange price of the shares over the three months preceding the date of the General Meeting at which the plan was adopted, less the per -share amount of dividends resolved by the General Meeting of the Company in the period: • from 1 October 2026 to 31 August 2029 for the first tranche; • from 1 October 2026 to 31 August 2030 for the second tranche; • from 1 October 2026 to 31 August 2031 for the third tranche.

Consolidated quarterly report for Q3 2026 (PLN millions) 29 The Group considers the date on which the Company Supervisory Board approves the allocation of share options to individual eligible persons to be the plan commencement date and the date of determining the fair value of the respective tranches of the plan. 50,000 options to acquire shares (subject to meeting the conditions of the plan) from the first tranche of the plan were allocated on 24 September 2026. The fair value of this tranche of the plan has been determined by an independent actuary at PLN 22.4 mi llion and will be recognised as an expense over the vesting period, i.e. over three years, taking into account the estimates regarding the fulfilment of non -market conditions. 20.

Explanation of the reasons for material changes in the items of income and expenses In the 9-month period of 2026, compared with the corresponding period of the preceding year, material changes in the particular items of income and expenses included: • sales higher by PLN 420 million, resulting mainly from higher sales volumes and higher product prices, including due to higher prices for aluminium and petrochemicals; • total costs of operation higher by PLN 272 million, of which mainly: o depreciation higher by PLN 5 million, reflecting the effect of the investment projects carried out; o materials and energy higher by PLN 252 million, resulting mainly from the larger scale of production. In the 9 -month period of 2026, the prices of aluminium (in PLN) were higher by 26% compared with the corresponding period of 2025; o third-party services higher by PLN 26 million, resulting from both the larger scale of operations and higher unit costs of these services; o employee benefits expenses higher by PLN 43 million, resulting mainly from higher salaries; o inventories of finished products and work in progress higher by PLN 122 million in the 9-month period of 2026 compared with inventories higher by PLN 67 million in the 9 -month period of 2025, reflecting changes in the value of finished products and work in progress in the current period, resulting mainly from the la rger scale of production in 2026 and higher costs of raw materials. As a result, profit on sales in the 9 -month period of 2026 amounted to PLN 780 million and was higher by PLN 148 million compared with the corresponding period of the preceding year. This is mainly due to higher sales volumes and, to some extent, the posit ive impact of the accounting effect of inventory turnover in the context of rapidly increasing prices of raw materials used by the Group following the outbreak of the conflict in the Middle East. Profit on operating activities in the discussed period amounted to PLN 784 million and was higher by PLN 145 million compared with the corresponding period of the preceding year. Net finance expenses lower by PLN 10 million in the 9 -month period of 2026 compared with the corresponding period of the preceding year result mainly from interest expenses on account of debt. • Upon consideration of income tax expenses higher by PLN 28 million, resulting from higher gross revenue, net profit for the 9-month period of 2026 amounted to PLN 594 million and was higher by PLN 128 million than in the corresponding period of the preceding year. 22. Explanation of the reasons for material changes in other items As at 30 September 2026 compared with 31 December 2025 major changes in the balance -sheet items comprise: • property, plant and equipment, right -of-use assets and intangible assets lower by PLN 45 million, resulting mainly from their depreciation and amortisation amounting to PLN 183 million, and capital expenditure of PLN 138 million; • increase in goodwill from PLN 27 million to PLN 40 million, resulting from remeasurement of deferred tax liabilities relating to the accounting for the acquisition of Selt Sp. z o.o. in 2024; • inventories higher by PLN 214 million, resulting mainly from higher volume of inventories, and higher aluminium prices affecting their valuation; • receivables higher by PLN 287 million, resulting mainly from lower trade turnover at the end of 2025;

Page 32

Consolidated quarterly report for Q3 2026 (PLN millions) 31 • equity higher by PLN 140 million, resulting mainly from net profit of PLN 594 million earned in the 9 - month period of 2026, shareholders’ decision to pay dividend for 2025 in the amount of PLN 483 million, and payments related to the exercise of share options in the amount of PLN 8 million; • loans lower by PLN 209 million, resulting mainly from positive cash flow from operating activities in the 9-month period of 2026, allocated to reducing debt in current accounts and paying the first tranche of dividend amounting to PLN 161 million; • dividend payables recognised in the amount of PLN 322 million as a result of the shareholders’ decision to pay dividend for 2025 in two tranches; • liabilities higher by PLN 182 million, resulting from trade payables and state payables, as a reflection of larger scale of operations compared with the end of 2025, and lower liabilities on account of purchase of property, plant and equipment. 23. Discontinued operations In the 9 -month period of 2026 and the 9 -month period of 2025, the Group did not discontinue any material operations. 24. Business combinations In the reporting period ended 30 September 2026, there were no business combinations or acquisitions of non - controlling interests. However, on 14 September 2026, the Company made a share purchase agreement (SPA) to acquire 100% of the shares in Fengari Holdings I B.V., the owner of the METRA Group, an international manufacturer of aluminium profiles and a provider of advanced processi ng services. The METRA Group conducts manufacturing operations in Italy, the United States and Canada, and generates annual revenue estimated at approx. EUR 600 million. The transaction is part of the Group’s growth strategy, aimed at strengthening its position in the European aluminium processing sector, expanding its operations in the North American market, and increasing geographical and product diversification. Synergies are also expected in the areas of technology, procurement and sales. The enterprise value of the METRA Group has been set at EUR 645 million. The final equity value, after accounting for net debt and standard transaction adjustments, may amount to up to EUR 450 million, depending on the transaction closing date. The closing of the transaction is subject to meeting standard conditions precedent, in particular the obtaining of the necessary competition and regulatory approvals in the relevant jurisdictions. The acquisition is to be financed through the Company’s own resources and debt financing. Therefore, the Company made a term loan agreement for up to PLN 2.0 billion with Bank Polska Kasa Opieki S.A. Since the transaction is denominated in EUR, the Company gradually hedges the future EUR/PLN exchange rate using options and conditional forward contracts. As at 30 September, the Company held call options for EUR 100 million exercisable in the first quarter of 2027. At present, the Management Board considers that the transaction will not have a material effect on the current dividend policy of the Group. Since the conditions allowing the Company to obtain control of the METRA Group had not been met by the reporting date, the effects of the transaction were not recognised in the consolidated financial statements for the current reporting period.

Consolidated quarterly report for Q3 2026 (PLN millions) 32 25. Financial risk management objectives and principles The objectives and principles of financial risk management have not changed compared with those presented in Note 32 of the consolidated financial statements for 2025. Below presented is detailed information concerning fair values of financial instruments that can be estimated: • cash and cash equivalents, short-term bank deposits and short-term bank loans – the fair value of the said instruments is close to their carrying amounts due to their short-term maturity; • trade receivables, other receivables, trade payables and other liabilities – the fair value of the said instruments is close to their carrying amounts due to their short-term nature; • long-term bank loans and leases – the fair value of the instruments is close to their carrying amounts due to variable interest rates and the market level of the margin; • financial derivatives are recognised at fair value determined as at the reporting date. 26. Capital management Capital management principles have not changed with regard to those disclosed in Note 36 of the consolidated financial statements for 2025. The Group monitors the return on equity using the ROE ratio, which is calculated as net profit for the last 12 months to equity. The financing structure is monitored using the net financial leverage ratio, which is calculated as net debt to the sum of equity and net debt, as well as the net debt to EBITDA ratio for the last 12 months, whereas EBITDA is understood to be operating profit plus depreciation and amortisation. In its net debt calculation, the Group includes interest-bearing loans and borrowings, as well as lease liabilities, less cash and cash equivalents. The Group considers a net financial leverage ratio of up to 50% and net debt to EBITDA ratio of up to 2 to be optimal. The basic objective of capital management is to maximise the return on equity while maintaining a secure and flexible financing structure. When preparing the specific guidelines, the division into operating segments is taken into account as well as the nee d to maintain current liquidity and ensure financing of growth objectives, in accordance with the adopted business strategy. In order to retain or adjust the capital structure, the Group may change the amount of dividend payable, return capital to shareholders, or issue new shares. In the reporting periods presented, no changes were introduced in the objectives, principles and processes in that area. 30.09.2026 31.12.2025 EBITDA (operating profit plus depreciation and amortisation) for the last 12 months 1,171 1,021 Net profit for the last 12 months 696 569 Interest-bearing loans and lease liabilities 1,220 1,436 Cash and cash equivalents (74) (64) Net debt 1,146 1,372 Equity 2,140 2,000 Equity and net debt 3,286 3,372 Net financial leverage* 35% 41% Net debt to EBITDA 1.0 1.3 ROE 32.5% 28% * Calculated as net debt/equity and net debt.

Contingent liabilities 30.09.2026 31.12.2025 Performance bonds for contracts provided by the ASS 5 10 Total 5 10 The validity periods of performance bonds for construction contracts depend on the provisions of respective contracts. Moreover, the Group is a party to a Power Purchase Agreement (PPA) for purchase of energy from renewable sources (RES). The agreement is binding for the years 2026-2029. It provides for the Group to physically purchase, in each year, 8,654 MWh of electricity at a fixed price, for PLN 3.48 million per year. Under the agreement, Grupa Kęty is able to flexibly plan its energy requirements and collectively balance the energy requirements of the companies within the Group, while being guaranteed that renewable energy from a specific generation source is supplied. Purchase of green energy under the PPA is directly related to the performance of sustainable development targets set out in the strategy of Grupa Kęty. 28.

Consolidated quarterly report for Q3 2026 (PLN millions) 38 II. OTHER INFORMATION APPLICABLE TO THE CONSOLIDATED QUARTERLY REPORT 1. Summary of the Issuer’s material accomplishments or failures in the reporting period and a list of major events relating to them High level of production capacity utilisation. Despite economic downturn prevailing in many markets during the holiday period and uncertainty regarding the price trends of key raw materials, the Capital Group secured orders in volumes sufficient to maintain a high level of capacity utilisation (80 -90%) at particular segments. Loan to finance an installation of the third BOPP film production line. As part of an investment project in the Flexible Packaging Segment, on 6 July 2026, Alupol Films Sp. z o.o. in Oświęcim made a non -revolving investment loan agreement for up to PLN 200 million with Bank Gospodarstwa Krajowego. The loan will be used to finance and refinance the aforesaid investment project. The line commissioning is planned for mid -2028. Acquisition agreement. On 14 September 2026, Grupa Kęty S.A. made a conditional share purchase agreement with Fengari Holdings Coöperatief U.A. with its registered office in Amsterdam, the Kingdom of the Netherlands, an entity incorporated under Dutch law and controlled by enti ties related to KPS Capital Partners, LP (‘Seller’), and with Fengari Holdings I B.V. with its registered office in Amsterdam, the Kingdom of the Netherlands, incorporated under Dutch law (‘Target Company). The purpose of the agreement is to acquire by Grupa Kęty S.A. of 100% of the shares in the Target Company’s share capital from the Seller (‘Transaction’). The Target Company is the sole shareholder of the METRA Group companies, including Metra – Metallurgica Trafilati Alluminio S.p.A. with its registered office in Rodengo -Saiano, Italy. METRA is a global, vertically integrated manufacturer of aluminium profiles, including advanced solutions for the railway sector and architectural systems, as well as a provider of high value -added services, including pain ting, anodising, machining and welding. METRA has nine production facilities in Italy, the United States and Canada, with a combined extrusion capacity of approx. 145,000 tonnes per annum, of which approx. 35% is in Europe. The sales of METRA Group are estimated at approx. EUR 600 million in 2026, while EBITDA net of one-off items, including transaction costs, is estimated at approx. EUR 90 million. The purchase price has been determined based on an enterprise value of EUR 645 million, less bank debt and other debt-related items, as at 31 March 2026. The equity value, after accounting for net debt of the METRA Group, is also dependent on the closing date of the Transaction and may amount to up to EUR 450 million. The closing of the Transaction is subject to meeting standard conditions precedent, including, among others, obtaining of the necessary approvals from competition authorities and other regulatory bodies (also those required under applicable foreign investment control regulations) in the relevant jurisdictions. Therefore, the closing of the Transaction is not certain and remains subject to meeting the aforesaid conditions precedent. Making of a loan agreement in connection with the acquisition agreement. To finance the aforesaid transaction, on 14 September 2026, Grupa Kęty S.A. made a term loan agreement for up to PLN 2,000 million with Bank Polska Kasa Opieki S.A. The final repayment date for the loan will be 24 months from the date of the loan agreement. The term loan will be a non -revolving loan that may be drawn down in PLN or EUR. The loan will bear interest at a variable rate, calculated as the sum of the relevant base rate, namely WIBOR or EURIBOR, and the Bank margin.

Consolidated quarterly report for Q3 2026 (PLN millions) 39 2. Factors with material impact on the results of the current quarter Demand for the Company products From a sales perspective, the most important customers are those from the three sectors of the economy: construction, industry, food and other FMCG manufacturers. The situation in the Polish construction sector in the third quarter of 2026 was marked by significant volatility, with an increase in public and infrastructure projects on the one hand, and stabilisation in the building and residential segments on the oth er. Large-scale public, energy and railway projects, financed in part by EU funds, remain the main drivers of the market (Statistics Poland [GUS] data for August show a sharp 29% y/y increase in construction and assembly output in the civil engineering sec tor). During the same period, building construction saw a decline of nearly 20% y/y, while the residential sector is facing a high market base and a cautious approach from developers who still have a large portfolio of completed units, which translates int o a selective approach to launching new projects. The situation in the Polish industrial sector in the third quarter was also highly volatile. The August figures indicate an increase in demand in sectors such as the manufacture of electrical equipment (+18.7% y/y) and the manufacture of machinery and equi pment (+12.8% y/y), while traditional consumer sectors are experiencing difficulties – manufacture of furniture fell by 2.3% y/y and the automotive sector (vehicles and trailers) contracted by 1.5% y/y. The food industry confirms its position as the largest and most stable segment of the Polish industrial sector. Statistics Poland data for August indicate stable growth in non -durable consumer goods (with production increasing by 4.8% y/y in August), while retail sales at constant prices rose by 3.8% y/y. Exchange rates As estimated, over half of the Group sales are denominated in foreign currencies, mainly EUR. On the costs side, also half of the expenses are expressed in foreign currencies, mainly in EUR and USD. In the third quarter of 2026, the average EUR/PLN exchange rate amounted to 4.3246 and was higher by approx. 2% than in the corresponding period of the preceding year. The average USD/PLN exchange rate amounted to 3.7586 and was higher by 3% y/y. With regard to the FX position of the Capital Group, PLN depreciation against EUR has a positive impact on the profitability of exports and the competitive position on the Polish market. In addition, the Capital Group companies have trade receivables and p ayables in foreign currencies. From this perspective, EUR fluctuations against PLN are of key importance. Prices of basic raw materials Aluminium (including aluminium scrap, aluminium sheet and aluminium foil) is the basic raw material used by the Capital Group, accounting for approximately half of the costs of materials. The Capital Group is therefore exposed to the risk of fluctuations in the prices of aluminium on the London Metal Exchange (LME), which form the basis for the contracts made by the Group companies. In the third quarter of 2026, the average 3M price of aluminium was approx. USD 3,225 per ton, which means an increase by abou t 23% in USD and by 27% when translated into PLN compared with the corresponding period of the preceding year. Short -term fluctuations in the prices of aluminium may affect the profitability of operations, particularly at the Extruded Products Segment, the Architectural Systems Segment and the Sun-shading Systems Segment, as the effect of price fluctuations is passed on to customers with a certain delay (1 -1.5 months at the EPS, and 2-3 months at the ASS and the SSS). A factor stabilising the generated resu lts are transactions hedging the aluminium purchase prices and, to some extent, the natural hedge provided by product pricing based on current prices of raw materials. Debt At the end of this reporting period, the Capital Group had debt amounting to PLN 552 million in long -term loans and PLN 605 million in short-term loans. Approx. 12% of the value of loans was held in foreign currencies (mainly in EUR), which is reflected in the statement of profit or loss by way of monthly measurement of the impact of foreign currency fluctuations on the value of the loans.

Consolidated quarterly report for Q3 2026 (PLN millions) 40 3. Factors which in the Issuer’s opinion are likely to affect its performance within the perspective of at least one quarter Demand for the Company products The most significant impact on achieving the assumed sales level will be brought by the situation in the construction sector, both in Poland and on the European markets, where over 50% of the consolidated revenue of the Capital Group comes from, and sales in the FMCG sector, for which the Flexible Packaging Segment manufactures packaging (approx. 20% of consolidated sales). In the construction sector, the Management Board expects the demand to remain at a level similar to that of the third quarter, except f or sun protection products (pergolas, awnings, etc.), where the demand in the fourth quarter drops regularly by approx. 30 -40% compared with the third quarter. As regards packaging sales, the pre -Christmas season contributes to higher FMCG consumption and, thus, the demand for packaging may be higher by several percentage points compared with the third quarter. Nevertheless, it depends on the current consumer sentiment. Similarly, as in the previous years, the demand for the Capital Group products will be significantly reduced seasonally in December owing to production downtimes at many of the customers and the Capital Group itself, and because of the Christmas season. Exchange rates Considering the FX position of the Capital Group, any possible appreciation of PLN against EUR will be negative for the sales and margins. Therefore, the Group intends to maintain a part of debt in foreign currencies and continue the policy of hedging currency risk with forward and futures contracts. Prices of basic raw materials Given no signs of economic recovery, the Group expects high volatility in raw material prices in the coming months of 2026. Debt It is estimated that the value of the Capital Group net debt is going to increase in the fourth quarter of 2026 by about PLN 0.3 billion, mainly on account of the operating results of the fourth quarter of the year, second tranche of the dividend payment, as well as payments related to the capital expenditure process. The costs of debt servicing in the coming quarter will increase due to higher debt level. The median of financial institutions’ forecasts implies that interest rates will remain unchanged in the fourth quarter. Approx. 13% debt of the Company bears interest at fixed rate or is secured with IRS transactions. 4. Organisational and management structure Grupa Kęty S.A. with its registered office in Kęty, at ul. Kościuszki 111, 32 -650 Kęty, is the parent company of the Capital Group of Grupa Kęty S.A. consisting of 23 companies, in which the Issuer holds, directly or indirectly, 100% of the share capital a nd all voting rights in General Meetings.

In accordance with the information provided, the supervising persons of the Company did not hold any shares of Grupa Kęty S.A. or rights to the same as at the date of this interim report publication (no change since the date of the previous interim report publication). 7. Material proceedings pending before a court, arbitration tribunal or a public administration authority In 2021 and 2022, Alupol Packaging S.A. and Alupol Packaging Kęty Sp. z o.o. (‘Companies’) within the Flexible Packaging Segment of the Issuer’s Capital Group imported aluminium foil from Thailand, used in the production of packaging. The import for the pu rposes of calculating customs fees was treated as import of goods originating in Thailand, which had been confirmed with the goods certificates of origin issued by Thai state authorities. In 2023, the transactions were subject to customs and fiscal inspect ion carried out by the Customs and Fiscal Authority of Silesia in Katowice and the Customs and Fiscal Authority of Pomerania in Gdynia. Contrary to the stand of the Companies and the evidence submitted by the same, the inspectors determined that the export of aluminium foil to the EU in the inspected period resulted from moving the operations by the foil manufacturer from China to Thailand solely for the purpose of avoiding anti -dumping and compensatory measures imposed on Chinese foil. Based on the decisions issued, customs duty was imposed on the Company in the total amount of PLN 37.2 million plus interest of PLN 11.5 million. The amounts were paid within the statutory deadline in 2024. The Companies disagree with the decisions of the Customs Authorities and filed appeals to the second instance authorities, indicating selective and arbitrary assessment of evidence by the Customs and Fiscal Authorities, which had only accepted evidence sup porting their stand. In 2025, the Companies received decisions of the second instance authorities sustaining the decisions of the first instance authorities. Therefore, the Companies filed complaints against the said decisions in whole with the competent Provincial Administrative Courts in Gdańsk and Gliwice. At the turn of 2025 and 2026, the Provincial Administrative Courts dismissed the Companies’ appeals. As at the day of preparing this interim report, the Companies filed cassation appeals with the Supreme Administrative Court. The cassation proceedings are pending. Apart from the aforesaid matter, in the period covered with this interim report no proceedings were initiated or pending against the Issuer or its subsidiaries before a court or public administration authority concerning any material liabilities or claims of the Issuer or its subsidiaries.
