4 CEO Letter: Q2 2026 Dear Shareholders, In 2026 to date, we have operated in a highly volatile environ- ment. Geopolitical disruptions have increased macroeconomic uncertainty , elevated cost inflation and raised financing costs, which in turn weighed on investor sentiment. In particular , this led to weaker-than-expected residential new-build activity , particularly in North America and the UK. However , in this environment, we managed to increase Q2 rev- enue by 13% year on year to EUR 1.4 bn. This top-line growth was driven by 7% organic growth, supported by volume and price increases, as infrastructure and renovation-led activities compensated for weaker-than-expected residential new-build activity , and by a 6% contribution from M&A. This performance underscores the success of the most significant portfolio transformation in wienerberger’s history , which has been at the center of our Group strategy for years. Resilience through transformation Through targeted acquisitions, we have successfully reduced our exposure to cyclical residential new-build construction mar- kets and increased our focus on infrastructure and renovation activities. T oday , more than 60% of our revenue is generated in these structurally resilient markets, positioning us for sustaina- ble growth and long-term value creation. Acquisition of Italcer marked a milestone in our transformation journey In April, we completed another significant milestone in our portfolio transformation. By acquiring Italcer , an Italian spe- cialist in ceramic wall and floor surfaces, we strengthened our exposure to renovation-driven end markets with an attractive long-term growth outlook. In addition to its financial contri- bution, Italcer provides us with a scalable platform for further growth and consolidation in the ceramic surface industry . T ogether with other targeted acquisitions, such as the leading roofing specialist T erreal in 2024, this transaction significantly strengthens our position in the resilient renovation market, allowing us to benefit from growing demand across regions. Likewise, our infrastructure-led piping activities, wienerberger Group’s largest segment by revenue, benefit from sound growth driven by , among other factors, climate adaptation, urbanization and public investment in utilities such as water management. Building on our strong piping platform, we continue to enhance our position through acquisitions, such as the NEWS Group, a leading provider of sustainable wastewater solutions in Sweden and the broader Nordic region, which we added to our portfolio in April 2026. Cost discipline and efficiency measures Despite our satisfactory revenue development, operating EBITDA fell short of our expectations in Q2 and amounted to EUR 230m, compared with EUR 253m in the same period of 2025. This decrease was due to unexpected declines in individ- ual residential new-build markets and elevated cost inflation resulting from geopolitical conflicts. T o counterbalance the ongoing challenges, we have implemented price increases to offset cost inflation and are actively managing our cost position and capacity levels. In addition, we intensified our “Fit for Growth” program, focusing on efficiency across operations, capital expenditure and working capital management. At the same time, we are also firmly focused on managing our balance sheet. Following the compelling strategic opportu- nity to acquire Italcer , our net debt / operating EBITDA ratio increased towards the high end of our framework for financial discipline. By targeting a significant reduction of this ratio to 2.4x by the end of 2027, we will thereafter consistently pro- gress towards our long-term goal of 2.0x net debt / operating EBITDA. We stay on course We expect the economic environment to remain volatile and challenging for the rest of the year , as geopolitical tensions persist. Accordingly , we have updated our 2026 guidance for operating EBITDA to EUR 700m. Against this background, our relentless focus on disciplined execution and strategic transformation remains key . We are highly committed to developing new solutions for affordable and sustainable construction that improve the quality of life of current and future generations. By continuously broadening our portfolio, we have not only become more resilient but have also strengthened our position for future growth. Sincerely , Gerhard Hanke Interim Chairman of the Managing Board of Wienerberger AG CEO & COO Central & East

7 Interim Management Report | Condensed Interim Consolidated Financial Statements Revenue development For wienerberger , the first half of 2026 has been characterized by strong top line performance, against the backdrop of severe winter weather in January and February as well as a challenging macroeconomic environment and geopolitical tensions from March onwards. These factors caused a contraction in the new residential housing end market, especially in key countries like the US, Canada and the UK, and generalized cost inflation ultimately pressuring profitability . The group generated revenues of EUR 2,434m (H1 2025: EUR 2,346m), including contributions from the consolidation of newly acquired companies in the amount of EUR 84m (H1 2025: EUR 1m), driven by the acquisition of Italcer and NEWS Group. Earnings and margin development Gross profit amounted to EUR 841m (H1 2025: EUR 849m). Consequently , gross margin declined to 34.5% from 36.2% in the prior-year period. The margin development was mainly attrib- utable to higher production costs, increased idle-capacity costs and continued inflationary pressure on personnel and logistics expenses. Selling expenses increased due to higher freight costs and the impact of Italcer . Conversely , administrative expenses decreased 4% organically , reflecting the impact of Fit for Growth initiatives. Other operating income and expenses in the half year totaled EUR –104m (H1 2025: EUR –3m), including expenses related to restructuring measures in the amount of EUR 17m, costs related to M&A in the amount of EUR 7m and EUR 47m for the settlement of an antitrust lawsuit in the USA. As a result, EBIT declined to EUR 60m (H1 2025: EUR 198m). Operating EBITDA for the period came to EUR 326m (H1 2025: EUR 383m); EUR 16m thereof is the contribution of the newly acquired companies, Italcer and NEWS group. This results in an operating EBITDA margin of 13.4%. Financial result and net income The financial result amounted to EUR –59m (H1 2025: EUR –47m). Net interest expenses increased slightly , reflecting higher average debt levels following acquisition financing and seasonal working capital requirements. Profit before tax amounted to EUR 1m (H1 2025: EUR 151m). After income taxes (H1 2025: EUR –43m), a result after tax of EUR 0 (H1 2025: EUR 108m) was reported.

Non-current assets increased to EUR 4,458m (YE 2025: EUR 4,130m), with notable additions to Goodwill (EUR 152m) and Property , plant and equipment (EUR 157m) related to the acquisitions of Italcer and News Group. Current assets increased to EUR 2,518m (YE 2025: EUR 2,012m), related to a seasonal- ity driven increase in inventories and trade receivables, while cash and cash equivalents and other financial assets declined to EUR 212m (YE 2025: EUR 281m), partly reflecting the effect of the cash outflow, in the second quarter , for the Italcer acquisition. Equity position Equity amounted to EUR 2,749m as of 30 June 2026 compared with EUR 2,802m at year-end 2025. The decrease primarily reflects dividend payments. These effects were partly offset by positive foreign currency translation differences and contribu- tions from newly acquired businesses. Liabilities T otal liabilities increased to EUR 4,228m (YE 2025: EUR 3,340m). The increase reflects, on the one hand, the additional financ- ing obtained in connection with acquisitions and refinancing activities. On the other hand, it is a direct consequence of the integration of newly acquired businesses and their pre-existing liabilities. Other current liabilities increased following the recog- nition of provisions related to the settlement of an antitrust case in the USA and restructuring measures.

11 Interim Management Report | Condensed Interim Consolidated Financial Statements Cash flows from operating activities Cash flows from operating activities amounted to EUR –107m as compared with EUR 28m in the prior-year period. Besides the lower earnings in the reporting period, the development was predominantly driven by a significant increase in working capital due to higher inventory levels and trade receivables. Cash flows from investing activities Cash flows from investing activities resulted in an outflow of EUR 253m, with the largest line item represented by the M&A capex, which amounted to EUR 157m and was primarily related to the acquisitions of Italcer and News Group. Maintenance and growth capex, combined, amounted to EUR 97m, in line with the same period of the previous year . Cash flows from financing activities and liquidity Cash flows from financing activities amounted to EUR 286m. The increase reflects additional debt financing raised to support acquisitions. Dividend payments amounted to EUR 104m. The liquidity , as of 30 June 2026, comprises cash and cash equiv- alents of EUR 138m and committed and fully undrawn credit facilities of EUR 570m, for a total of 708m. Free cash flow ultimately amounted to EUR –203m, mainly due to the adverse impact of the increase in trade receivables. Acquisitions During the first half of 2026, wienerberger continued to execute its growth strategy through targeted acquisitions, including Italcer , a globally active producer of ceramic solutions with man- ufacturing hubs in Italy and Spain, and NEWS Group, a leading provider of sustainable wastewater solutions in Sweden and the Nordic region. T otal M&A expenditure for the reporting period amounted to EUR 157m, consisting of the net payments for the aquisitions of Italcer of EUR 130m, NEWS group of EUR 17m, and an asset deal of EUR 2m, as well as the remaining payments for the past acqui- sitions of VETA France of EUR 7m and Summitville of EUR 1m.

During the first half of 2026, the region continued to benefit from its increased focus on renovation and infrastructure markets, while residential new-build activity remained subdued, espe- cially in the UK. Market development The infrastructure market remained stable during the first half of 2026, supported by investments in water and wastewater networks, power-grid upgrades and climate-adaptation projects. Following a slow start into the year due to the harsh winter , activity picked-up during the second quarter across most Con- tinental European and Nordic countries. Renovation has been stable-to-positive across the region, delivering a performance largely in line with expectations. Residential new-build demand, however , remained muted, particularly in the UK, and, to a lesser extent, in Germany and France, as affordability constraints and cautious investment decisions continued to delay a broader market recovery . wienerberger performance External revenues increased to EUR 1,445m (H1 2025: EUR 1,379m), driven mainly by pricing initiatives that were already effective in the middle of the second quarter , which helped to partly recover the significant volume decline in the UK. Operating EBITDA declined to EUR 189m (H1 2025: EUR 205m), as cost increases in raw materials pressured margins. The full impact of announced price increases is expected in the second half of the year . wienerberger delivered a resilient performance in a challenging market environment. Roofing activities benefited from stable renovation demand and energy-efficiency upgrades across the existing building stock. Infrastructure and piping solutions recorded solid demand in water management, drainage and util- ity-network applications. In wall and façade products, continued pressure from weak residential construction and competitive market conditions weighed on demand, particularly in markets with high exposure to new-build housing. Disciplined pricing and ongoing optimization measures supported performance throughout the period.

Market conditions remained mixed during the first half of 2026, with signs of recovery emerging in several Central and Eastern European countries. Market development Construction activity gradually improved in several markets across the region. The Czech Republic and Poland benefited from stronger permitting activity , improving financing conditions and continued infrastructure investments, while Hungary showed early signs of recovery supported by housing-related stimulus measures. The Austrian market remained subdued due to afforda- bility constraints, lower subsidy support and cautious investment behavior . Infrastructure markets generally remained more stable than residential construction and continued to benefit from investments in water , wastewater and utility networks. wienerberger performance External revenues increased to EUR 667m (H1 2025: EUR 592m), thanks to a positive volume effect, especially in the second quarter , and to the effect of price increases already implemented to counteract the strongly negative impact of raw materials cost inflation. Operating EBITDA, on the other hand, declined to EUR 90m (H1 2025: EUR 103m), reflecting the portion of higher cost not yet covered by price increases implemented in the second quarter , as well as the weakness in the new residential end market in specific countries. wienerberger maintained its strong market positions through focused customer engagement, specification work and disci- plined commercial execution. Ceramics businesses benefited from improving market conditions in selected countries, while roofing activity remained broadly stable. Infrastructure and in-house piping solutions continued to perform relatively well, supported by demand from public-sector and utility-related projects. The region’s balanced exposure to residential, renova- tion and infrastructure applications helped mitigate continued weakness in certain construction markets.

The first half of 2026 was characterized by weak residential construction activity in both the United States and Canada, while infrastructure-related markets remained comparatively resilient. Market development Residential new-build activity remained significantly below expectations due to elevated mortgage rates, affordability con- straints and continued economic uncertainty . Housing demand in both the United States and Canada remained subdued. On the other hand, infrastructure-related markets continued to benefit from investments in water distribution, wastewater systems and utility-network modernization. wienerberger performance During the first half of the year , the region generated external revenues of EUR 322m (H1 2025: EUR 376m) and an operating EBITDA of EUR 48m (H1 2025: EUR 75m). The decline in both revenue and operating EBITDA was mainly driven by market con- ditions that were substantially below expectations, both in the United States and Canada, especially in new residential housing. wienerberger’s façade business continued to be affected by weak residential construction activity and lower demand across key housing markets. Roofing developed positively , supported by a strong backlog and stable project activity . The piping business benefited from its exposure to infrastructure and utility applications, although profitability remained affected by market-wide pricing pressure and higher raw material costs. Cost-control measures and operational improvements helped mitigate part of the impact from challenging market conditions.

15 Interim Management Report | Condensed Interim Consolidated Financial Statements Outlook Economic conditions According to the latest release of the World Economic Outlook ( July 2026), the IMF has revised the estimated global growth for 2026 downwards to 3.0% (previously 3.3%, January 2026). This reflects the lingering impact of the Middle East conflict that erupted in February 2026, only partly offset by stronger momen- tum in technology-related investment. The US growth forecast has been held broadly steady at around 2.3%, while the Eurozone outlook has been trimmed further to below 0.9%, weighed down by continued energy exposure and limited participation in the technology-led upswing. Global headline inflation has been revised upward to 4.7% (previously projected at 3.8%), with effects from the conflict remaining a key risk. The IMF estimates that energy prices will remain at higher levels than they were before the conflict. Financing conditions, which tightened sharply following the outbreak of hostilities in February , have since eased but remain restrictive by historical standards. Against this backdrop, resi- dential new-build markets in the United States, Canada, and the United Kingdom have continued to underperform expectations amid persistent affordability constraints and elevated financing costs, while infrastructure and renovation-driven demand across Continental Europe has proven comparatively resilient, supported by public investment programs and the ongoing decarbonization of the European building stock. wienerberger The first half of 2026 was characterized by a more challenging market environment than originally anticipated, as the recovery in residential new-build markets failed to materialize in several key geographic areas, most notably the United States, Canada, and the UK. Group revenues nonetheless grew to EUR 2,434m in H1 2026 (H1 2025: EUR 2,346m), supported by 1% organic growth and the contribution of recently completed acquisi- tions, while operating EBITDA declined to EUR 326m (H1 2025: EUR 383m) mainly due to the weakness in the new residential market. Reflecting the continued strength of infrastructure and reno- vation end-markets, which now account for more than 60% of Group revenues, combined with the accretive contribution from the Italcer acquisition completed at the end of April, wienerberg- er’s underlying business continues to demonstrate its resilience. However , given the weaker-than-expected trajectory of residen- tial new-build wienerberger now expects operating EBITDA of approximately EUR 700m. While a structural recovery in residential new-build activity is not yet visible, wienerberger’s continued transformation toward infrastructure, renovation, and other structurally more resilient end-markets is expected to support earnings stability and long term value creation.

Basis for preparation These condensed interim consolidated financial statements of wienerberger for the six-month period ended 30 June 2026 have been prepared in accordance with IAS 34 Interim Financial Reporting as adopted by the European Union. The interim financial statements do not include all information and disclosures required for a complete set of annual consolidated financial statements and should be read in conjunction with wienerberger’s consolidated financial statements for the financial year ended 31 December 2025. The accounting policies applied in preparing these interim financial statements are consistent with those applied in the financial statements for the year ended 31 December 2025. The preparation of interim financial statements requires management to make judgements, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, income and expenses; the related significant judgements and key sources of estimation uncertainty were consistent with those applied in the consolidated financial statements for the year ended 31 December 2025. Unless otherwise stated, all amounts are presented in millions of Euros (EURm). Amounts have been rounded in accordance with established commercial practice. As a result, rounding differences may occur . Notes to the Consolidated Interim Financial Statements Interim Management Report | Condensed Interim Consolidated Financial Statements

23 3. Changes in accounting policies The following amendments to IFRS® Accounting Standards became effective for reporting periods beginning on or after 1 January 2026 and were applied by the Group. Their initial application had no material impact on the Group’s financial position, financial performance or cash flows. IFRS® Accounting Standard Effective date Annual Improvements to IFRS Accounting Standards — Volume 11 1/1/2026 Contracts Referencing Nature-dependent Electricity – Amendments to IFRS 9 and IFRS 7 1/1/2026 Amendments to the Classification and Measurement of Financial Instruments – Amendments to IFRS 9 and IFRS 7 1/1/2026 The following new and amended IFRS® Accounting Standards had been issued but were not yet mandatory for reporting periods beginning on 1 January 2026 and were therefore not applied in the preparation of these interim financial statements. IFRS® Accounting Standard Effective date IFRS 18 Presentation and Disclosure in Financial Statements 1/1/2027 IFRS 19 Subsidiaries without Public Accountability: Disclosures 1/1/2027 IFRS 20 Regulatory Assets and Regulatory Liabilities 1/1/2029 Amendments to IFRS 19 Subsidiaries without Public Accountability: Disclosures 1/1/2027 Amendments to the Fair Value Option in IAS 28 Investments in Associates and Joint Ventures 1/1/2027 Amendments to IAS 21 The Effects of Changes in Foreign Exchange Rates: T ranslation to a Hyperinflationary Presentation Currency 1/1/2027 The Group has assessed the impact of new and amended IFRS® Accounting Standards that have been issued but are not yet effec- tive. Except for IFRS 18 Presentation and Disclosure in Financial Statements, which will result primarily in changes to the presenta- tion and disclosure of financial information, no material effects on the Group’s financial position, financial performance or cash flows are currently expected. IFRS 18 Presentation and Disclosure in Financial Statements is effective for annual reporting periods beginning on or after 1 January 2027. The standard will primarily affect the presentation and disclosure of information in the Group’s consolidated finan- cial statements. The most significant expected changes relate to the structure of the statement of profit or loss, additional disclosures regarding management-defined performance measures and enhanced aggregation and disaggregation requirements. The Group is currently assessing the detailed implications of IFRS 18 and continues to evaluate the impact on its reporting processes and systems.

24 4. Acquisitions During the six-month period ended 30 June 2026, the Group completed two acquisitions: Italcer and NEWS Group. As Italcer rep- resents the more significant transaction, detailed acquisition-date information is provided below. NEWS Group is not individually significant and is therefore disclosed in summary form. Since the acquisition date on 30 April 2026, the acquired businesses have contributed revenue of EUR 70m and operating EBITDA of EUR 13m to the Group’s interim financial statements for the six-month period ended 30 June 2026. Had these acquisitions been completed on 1 January 2026, Group revenue for the six-month period ended 30 June 2026 would have been approximately EUR 2,559m and Group operating EBITDA would have been approximately EUR 348m. Italcer The provisional fair values of the identifiable assets acquired, and liabilities assumed, the consideration transferred, the non-con- trolling interests recognized and the resulting goodwill are presented below. in EURm 30/4/2026 Intangible assets 21 Property , plant and equipment and financial assets 173 Non-current assets 193 Inventories 122 T rade receivables 79 Other receivables 26 Cash and cash equivalents 29 Current assets 256 Deferred taxes 9 Provisions 16 Financial liabilities 214 Non-current liabilities 238 Provisions 3 Financial liabilities 42 T rade payables 99 Other liabilities 27 Current liabilities 171 Net assets acquired 41 Non-controlling interests –20 Goodwill 139 Consideration transferred 159 Cash consideration transferred 159 Less: cash and cash equivalents acquired –29 Net cash outflow on acquisition 130 Interim Management Report | Condensed Interim Consolidated Financial Statements

25 Italcer On 30 April 2026, wienerberger acquired 50% + 1 of the shares in Italcer S.p.A. and its subsidiaries (“Italcer”), a leading Italian producer of ceramic surfaces. The acquisition has expanded wienerberger’s presence in the attractive ceramic materials market and is further strengthening its position in renovation and new-build end-markets. wienerberger acquired 50% + 1 of the shares in Italcer and obtained control. Non-controlling interests were measured at their pro- portionate share of the acquiree’s identifiable net assets. Accordingly , the partial goodwill method was applied. As of the date of authorization for issue of these condensed interim financial statements, the purchase price allocation for Italcer remained preliminary . Sufficient information was not yet available to reliably allocate the purchase consideration to the identifiable assets acquired and liabilities assumed. Due to the current state of Italcer’s systems, processes, and underlying data, which had not yet been fully aligned with wienerberger’s reporting and valuation standards, a robust determination of provisional fair values was not possible. Consequently , wienerberger has not remeasured any acquired assets or assumed liabilities as of 30 June 2026. Accordingly , the purchase price allocation remained incomplete as of 30 June 2026 and the amounts recognized are provisional. The identification and valuation of the acquired assets and assumed liabilities, including intangible assets and related deferred tax effects, are still ongoing. Pending completion of the valuation process, the excess of the consideration transferred over the provisional net assets acquired was recognized as provisional goodwill. The completion of the purchase price allocation is expected to result in material adjust- ments to the amounts currently recognized, including the separate recognition and measurement of identifiable intangible assets, corresponding deferred tax effects, and non-controlling interests. Accordingly , the provisional goodwill recognized as of 30 June 2026 may change significantly during the measurement period in accordance with IFRS 3 and should not be regarded as indicative of the amount of goodwill that will ultimately result from the completed purchase price allocation. It is expected that material intangible assets will be identified that will lead to the amortization from the purchase price allocation starting from the acquisition date 30 April 2026. NEWS Group On 30 April 2026, wienerberger acquired 100% of Northern Environmental and Water Solutions (“NEWS Group”), a leading Scandi- navian provider of sustainable wastewater and treatment solutions. The acquisition complements wienerberger’s existing business activities and further strengthens its market position in the relevant markets. As of the reporting date, the purchase price allocation had not yet been completed. The identification and valuation of the acquired assets and assumed liabilities, including intangible assets and related deferred tax effects, were still ongoing. Consequently , the amounts recognized are provisional. Pending completion of the valuation process, identifiable net assets acquired were recognized on a provisional basis at EUR 10 mil- lion and provisional goodwill amounted to EUR 13 million. The completion of the purchase price allocation is expected to result in adjustments to these amounts, including the recognition and measurement of identifiable intangible assets and related deferred tax effects. Accordingly , the provisional goodwill recognized as of 30 June 2026 is expected to change during the measurement period in accordance with IFRS 3 and should not be regarded as indicative of the final amount of goodwill. Cash consideration transferred amounted to EUR 23m. After deducting cash and cash equivalents acquired of EUR 6m, the net cash outflow from the acquisition amounted to EUR 17m.

Provisions As disclosed in the 2025 Annual Report, Pipelife Jet Stream, Inc., together with other PVC pipe manufacturers, is a defendant in antitrust litigation in the United States and is subject to a related investigation by the U.S. Department of Justice (DOJ). During the first half of 2026, developments in the litigation, including settlement agreements concluded by other defendants, the execution of a settlement agreement with one plaintiff class and the approval by the Management Board of a settlement strategy covering all remaining plaintiff classes, resulted in a reassessment of the related risks. Consequently , the Group concluded that the recognition criteria for a provision under IAS 37 were met and recognized a provision of EUR 47m as of 30 June 2026 Interim Management Report | Condensed Interim Consolidated Financial Statements
