Chief Executive's Review

Dear Shareholders,

As the very satisfactory mid-year results of our three Business Units show, we have emerged from the crisis stronger than before. Despite partly muted developments in its core markets and a slow return to the pre-crisis level, the Wienerberger Group generated record revenues of € 1,867.5 million in the first half of the year, up by 14% from the previous year. EBITDA LFL grew to € 308.4 million, which corresponds to a 21% increase compared to the prior year's period. Overall, we significantly surpassed even the record results of the first half of 2019. Our performance has thus caught up with the successful pre-crisis year 2019 and is again in line with the positive trends of recent years.

The record mid-year results for 2021 are attributable, above all, to organic growth through innovative product solutions and the consistent implementation of our Selfhelp program, thus confirming the success of our strategic orientation. The substantial progress achieved in the first

half of the year in our efforts to attain our ESG targets constitutes a central component of our success. Particularly in view of the most recent manifestations of climate change in large parts of Europe, we will continue to consistently pursue our sustainable growth strategy in line with ambitious ESG criteria and a special focus on innovation, sustainability and digitalization.

Wienerberger has set itself the ambitious target of reducing its CO² emissions by 15% until 2023 as compared to 2020 and becoming climate neutral by 2050 at the latest. I am proud to report that we are well on track to reach our ambitious targets by 2023. This is happening along the entire value chain from product development to sourcing to production and the use, re-use or recycling of our products. Today, Wienerberger is at the forefront of addressing increasing customer demand for sustainable solutions with its energy-efficient building material solutions, such as climate-neutral bricks, solar panels integrated into roof surfaces, and solutions for green facades in the renovation segment. Thanks to its smart infrastructure solutions for example in the area of rainwater management, the Wienerberger Group is also actively contributing to environmental protection to prevent flash flooding in both urban and rural areas.

The torrential rainstorms experienced in large parts of Europe emphasize the importance of sustainable solutions in energy and water management. In recent years, Wienerberger has already developed a wide variety of products and systems in this field. Moreover, as the effects of climate change become more and more noticeable, there is an increasingly strong argument for the use of robust construction materials. Bricks, thanks to their ability to regulate the indoor climate, are the ideal building material for meeting these challenges. Brick walls keep homes warm in winter and cool in summer and are therefore sustainable and resource-efficient. Playing a pioneering role in the construction industry, Wienerberger is focusing on the development of smart building materials and infrastructure solutions as well as value-enhancing innovations based on networking and digitalization for new build, renovation and infrastructure.

In line with past practice, the Wienerberger Group remains focused on achieving continuous growth in its

core markets and segments. This goal is being pursued through organic growth driven by innovations made possible by consistent investments in research, the development of new technologies, and the right talents on the one hand, and through external growth, on the other hand. The most recent acquisition of FloPlast in United Kingdom and Cork Plastics in Ireland has sustainably strengthened our position in the renovation and in-house segments and enables us, in particular, to provide smart and sustainable solutions for water management in both areas of business based on our combined product portfolio.

In general, our outlook for the second half of the year is positive. At the beginning of July, based on our expectation of an especially strong performance for the business year 2021, we announced an upward revision of our guidance for EBITDA LFL to € 620-640 million (previously € 600-620 million).

We assume that the high sales volumes of the first half of the year, especially in the infrastructure and renovation markets, will level off to a certain extent in the second half. Generally speaking, we foresee a continuation of the mostly positive development of the three Business Units. Additionally, enhanced internal value creation in the in-house and infrastructure segments thanks to Wienerberger's successful ongoing transformation into a full-range provider of smart system solutions will continue to ensure a satisfactory performance in the second half of the year.

Interim Management Report Financial Review

Earnings

During the first half of the year, revenues at Group level increased by 14% from the prior period's level to € 1,867.5 million (2020: € 1,641.5 million). This strong development is mainly attributable to the recovery of sales volumes after the crisis triggered by the Covid-19 pandemic in 2020. Despite a difficult environment in the procurement market, Wienerberger succeeded in broadening its product mix through its high-quality solutions and counteracting cost inflation by means of a proactive margin policy. Contributions from consolidation, primarily from Ammonit, a provider of façade solutions, and the Dutch technology company Inter Act taken over in the previous year, accounted for € 2.8 million in revenues. In contrast, foreign exchange effects diminished the Group's revenues in the first half of the year by € 25.3 million, which was primarily due to the depreciation of the US dollar, the Turkish lira, and the Polish zloty.

In the reporting period, the Wienerberger Group's EBITDA LFL grew by 21% to € 308.4 million (2020: € 254.1 million). The increase was attributable not only to higher revenues, but also to the continued implementation of efficiency-enhancing measures within the framework of the Self-help program. EBITDA LFL does not include proceeds from the disposal of core and non-core assets in the amount of € 5.1 million, contributions from consolidation of € 0.9 million, negative foreign exchange effects of € 4.3 million, and structural adjustment costs of € 3.1 million.

Under the impact of the drivers described above, EBITDA reported by the Wienerberger Group increased by 17% to € 307.0 million compared to the previous year's level of € 261.9 million. As a result of the positive operating performance, earnings before interest and tax (operating EBIT) also improved by 33% to € 181.3 million (2020: € 136.5 million).

The change in weighted average costs of capital (WACC), applied to discount the future cash flows in order to determine the value in use of the cash generating units (CGUs), was deemed to be a triggering event for the performance of impairment tests. For the CGU group Pipes Pipelife East, the impairment test resulted in a write-off of the entire goodwill in the amount of € 10.7

million. Nevertheless, earnings before interest and tax (EBIT) increased substantially year-on-year to € 170.6 million (2020: € 19.7 million). In this context, it is important to note that impairment charges of € 116.8 million were booked in the previous year.

The financial result declined to € -25.9 million from the previous year's level (2020: € -11.1 million). Essentially, it comprised net interest expenses of € -18.1 million (2020: € -17.5 million), valuation effects of derivatives of € 1.5 million (2020: € 10.8 million), foreign exchange differences of € -1.7 million (2020: € -5.2 million), and write-downs of subsidiaries in the amount of € -7.7 million (2020: € 0 million).

On account of the effects described above, profit before tax increased to € 144.7 million (2020: € 8.6 million). Nevertheless, the tax expense of € 31.1 million was slightly below the prior period's € 32.2 million, as there were significant non-taxable impairment effects in the previous year. After a negative net result of € -29.4 million in the first half of 2020, the reporting period closed with a positive net result of € 112.6 million. Earnings per share came to € 1.00 (2020: € -0.26) for the reporting period.

Cash Flow

In the first half of the year, gross cash flow increased to € 236.9 million (2020: € 187.8 million), which was primarily due to the positive operating performance. Cash flow from operating activities also improved from € 34.6 million in 2020 to € 90.7 million in the reporting period.

During the first half of the year, a total amount of € 82.1 million (2020: € 70.0 million) was spent on investments in non-current assets (incl. financial assets), € 43.3 million of which was accounted for by maintenance capex (2020: € 46.1 million). Additionally, the Group invested € 32.0 million (2020: € 21.9 million) in the optimization of production processes, the development of new products, digitalization, innovation and sustainability (special capex). Investments in non-current financial assets and the acquisition of companies amounted to € 6.8 million (2020: € 2.0 million). In the reporting period, proceeds from the sale of real estate and the realization of other

non-current assets came to € 15.5 million (2020: € 20.2 million).

Cash flow from financing activities in the reporting period amounted to € -246.5 million (2020: 348.3 million). Cash outflows primarily comprised € 225.4 million for the redemption of the hybrid bond including the coupon determined in the previous year. As resolved by the 152nd Annual General Meeting, a dividend of € 67.4 million was paid out.

In total, the Group's cash position declined by € 216.5 million from the 2020 year-end value to € 449.6 million, whereas € 292.7 million accrued to shareholders.

Assets and Financial Position

Comprehensive income after tax resulted in an increase in the Group's equity by € 151.7 million, whereas the distribution of dividends in the amount of € 67.4 million reduced equity accordingly. On balance, the Group's equity increased by € 85.7 million in the first half of the year.

The increase in net debt to € 946.1 million in the reporting period (from € 882.1 million as at 31/12/2020) is primarily attributable to the usual seasonal build-up of working capital.

Operating Segments

Wienerberger Building Solutions

In the first half of 2021, the Wienerberger Building Solutions Business Unit achieved a very satisfactory result in an overall positive market environment, with some core markets still below pre-crisis levels:

• › Notable 10% increase in external revenues to € 1,115.4 million (2020: € 1,014.4 million)
• › Strong EBITDA LFL growth of 19% to € 219.2 million (2020: € 184.4 million)
• › Continuing high demand, especially for roofing solutions in all markets
• › Effects of weather-related challenges in the first quarter have been overcome
• › Outlook: We expect to see a continuing positive market development and satisfactory demand in our core markets.

During the first six months of 2021, the Wienerberger Building Solutions Business Unit generated very satisfying results. After a late start of the construction season due to unfavorable weather conditions in some of our core markets, lively renovation activities in all key markets and solid demand in new residential construction in Western Europe resulted in notable growth, which more than offset the somewhat muted developments in Eastern Europe.

The implementation of our Self-help program, comprising further efficiency-enhancing measures, stricter cost management, and new digital solutions, also contributed significantly to the Business Unit's performance. Additionally, price increases were implemented successfully to cover cost inflation.

In many of our markets we recorded increasing numbers of building permits issued, which had a positive impact on demand for our products. Moreover, intensive renovation activities resulted in a high level of capacity utilization in our roofing plants across all our markets.

Thanks to excellent cooperation and cross-regional product management, we were able to deliver our products on schedule in all regions.

Overall, our Western European markets delivered a very satisfying performance in the first half of 2021. Great Britain, in particular, continued to generate good results. Among other factors, the positive development of the residential construction market was attributable to government support for housing. Solid demand for our building solutions led to a high level of capacity utilization in our plants and lower inventory levels than in previous years. Nevertheless, on-schedule product deliveries were guaranteed. Belgium saw particularly high demand for renovation solutions, and our wall and façade segments benefited from increasing new construction activity. As a result, earnings generated in the first half of 2021 significantly surpassed the pre-crisis level. In the Netherlands, strict emission control laws continued to have a dampening effect on residential construction. However, these impacts were largely offset by consistently high demand for our innovative solutions in the roof and paving segments, with

earnings in general returning to pre-crisis levels. In Germany, the negative influence of delayed project starts due to harsh weather at the beginning of the year was caught up in the second quarter of 2021. With solid levels of demand in all product groups, especially in the roof segment, France achieved a notable increase in earnings. In Denmark, thanks to a stable market environment and the successful further development of our range of premium products, we generated sound half-year earnings.

Overall, our Eastern European markets also recorded an increase in demand, though at a lower level than in Western Europe. In the previous year, governments in Eastern Europe relied on comparatively moderate strategies in the fight against the pandemic, which meant that most of our production plants remained in operation during the second quarter of 2020. In our Eastern European core markets, the onset of winter delayed the start of the construction season in several regions, whereas a significant catch-up effect was observed in subsequent months. Poland was the country that suffered most from bad weather conditions at the beginning of the year. Demand in new build began to rise in the second quarter but remained below the pre-crisis level. Increased renovation activities resulted in higher sales volumes in the roof tile segment. The Czech Republic saw muted demand in the clay block market, which was, however, offset by high demand for roofing solutions.

The situation was similar in Slovakia, Hungary and Romania, with Hungary benefiting from government subsidy programs for renovation and the construction of family homes. In Austria, demand showed an increased level across all product groups, driven by sound construction and renovation activities, with plants operating at full capacity. In this solid market environment, our operations in Austria closed the first half of the year with a record result. In our Southern East European markets, Croatia, Serbia and Slovenia delivered excellent earnings, driven by increased demand for wall and roof solutions, whereas the results in Bulgaria remained below the pre-crisis level.

In our Eastern European paver business, we consistently pursued our strategy focused on high-value products. Despite a weather-related late start to the construction season, especially in Poland, we succeeded in generating solid earnings in this segment.

Outlook for 2021

In general, we are observing positive market developments, especially in the field of renovation, with a slow recovery and gradual convergence of most markets to precrisis levels in new construction. We therefore expect to see continuously high demand for our building solutions. Overall, we are seeing increased renovation activities in all our core markets. However, the outlook for the coming months may be dampened to a certain extent by a shortage of skilled labor to be expected in the medium term. Price increases in all fields of business are in line with our expectations and enable us to cover cost inflation. Thanks to our Self-help program, with its continued focus on operational excellence, special capex and investments in ESG, Wienerberger is well positioned to advance successfully on its growth path.

Overall, we anticipate a continuation of the mostly positive market developments in the second half of the year, provided that we will not be faced with substantial restrictions due to the Covid-19 pandemic.

Wienerberger Piping Solutions

Despite challenging conditions in the raw material markets, the Wienerberger Piping Solutions Business Unit delivered a record result:

• › Strong external revenue growth of 21% to € 569.7 million (2020: € 470.3 million)
• › EBITDA LFL up by 13% to € 60.0 million (2020: € 53.0 million)
• › Excellent supply chain management and successful procurement initiatives ensured product availability despite the difficult raw material situation.
• › Outlook: High demand for infrastructure and in-house solutions expected to continue. Extraordinarily high sales volumes of recent months likely to level off in the second half of the year.

Despite challenging conditions, our plastic pipe business delivered a record result in the first half of 2021. This was attributable, above all, to excellent supply chain management and successful procurement initiatives, as well as proactive margin management. Demand for infrastructure solutions was high during the first six months of the year. With its full range system solutions for water and energy management, Wienerberger scored a remarkable success in the market. Overall, the Business Unit's performance in the second quarter of 2021 was characterized by extraordinarily high sales volumes in all its markets.

The procurement market remained challenging throughout the second quarter, but thanks to our proactive margin management we were able to largely offset the impact of rising input costs. Raw material price increases began toward the end of the previous year and continued throughout the reporting period. Raw material shortages occurred owing to maintenance work and reports of force majeure events experienced by suppliers. At the same time, demand continued to increase in the USA and Asia. Despite the challenging situation in the raw material markets, successful inventory management, longterm supplier relations, and our optimized supply chain enabled us to meet our customers' demand at all times and to further strengthen our market position as a reliable partner.

During the first six months of the year, our Northern European markets performed at a satisfactory level. Norway benefited from increased sales of frost-resistant and pre-insulated plastic pipes. Despite the negative impact of raw material price developments, Sweden and Finland also generated solid results, not least thanks to an improved product mix. The expansion of the Ljung plant in Sweden, to be converted into the largest pipe production site in Northern Europe, and the construction of a new plant for the production of special pipes in Finland were further advanced in recent months. Thanks to high demand and proactive margin management, the Baltic countries delivered a solid half-year performance.

In Western Europe, strong demand for infrastructure projects and in-house solutions, combined with catch-up effects after the previous year's government-imposed Covid-19 measures, resulted in significant earnings

growth. Within our in-house business, the electro segment performed particularly well. In the Netherlands and Belgium, pre-wired "Preflex" system solutions accounted for a significant contribution to earnings.

Austria generated very satisfying half-year results, driven by high demand in all fields of business, supported by governmental investment premiums. Our business in the other Eastern European markets also delivered highly satisfactory results, with Poland, the Czech Republic, and Hungary contributing significantly to earnings growth. These very satisfactory results were primarily attributable to high demand for infrastructure and full range solutions for large-scale projects and to growing momentum in the agricultural segment. In Eastern Europe, the infrastructure segment continued to benefit from EU support programs for the expansion and renovation of pipe networks.

Outlook for 2021

The situation in the raw material markets is expected to remain tense, although a gradual trend toward supplyside easing has been observed in recent weeks. Price increases have so far been largely offset through proactive margin management. Thanks to excellent supply chain management and successful procurement initiatives, the raw material price effects in the reporting year will be significantly lower than originally expected. Wienerberger expects to see a continuously sound level of demand for infrastructure and in-house solutions in the second half of the year, although the extraordinarily high sales volumes of the first half of the year are likely to level off to a certain extent, especially in Eastern Europe.

Acquisition of FloPlast and Cork Plastics

FloPlast and Cork Plastics, two full-range providers of wastewater and rainwater solutions, acquired in July 2021, will strengthen Wienerberger's presence in the British and Irish renovation and in-house markets. These companies are an excellent fit for Wienerberger's current range of building solutions. Through these acquisitions, Wienerberger is accelerating its transformation into a provider of full-range systems by combining its own portfolio of roof products with supplementary roofline, rainwater and drainage solutions supplied by FloPlast ("from rain to drain") and integrating them with its smart water collection, filtration and irrigation solutions. At the same time, the combined product portfolio offers increased cross-selling opportunities in private and public new residential construction, a field in which Wienerberger already holds a leading position in Great Britain.

North America

The North America Business Unit, continuing on its growth path, generated very satisfying results in the first half of 2021:

• › External revenues increased by 16% to € 180.2 million (2020: € 154.9 million)
• › EBITDA LFL increased in a very positive way by 74% to € 29.2 million (2020: € 16.8 million)
• › Earnings driven primarily by strong plastic pipe business and sound performance in Canada
• › Outlook: Continuing positive market environment in new build expected to support demand for façade solutions. The demand for plastic pipes should continue thanks to infrastructure programs.

During the first six months of the year, developments in the North America Business Unit were influenced by a positive market environment in new build and high demand in the infrastructure segment. Very satisfying results were recorded, in particular, in the plastic pipe business and the Canadian façade business. The US business suffered from extreme weather conditions at the beginning of the year, but, starting in March, it also benefited from high demand in new build.

In March 2021, the number of new housing starts, reflecting the growing momentum in US residential construction, reached its highest level in 15 years. As a result, we saw strong demand for our façade solutions. At the same time, we took advantage of growing demand for interior design elements. In combination with successfully implemented price increases to cover cost inflation, this led to sound half-year earnings.

With demand for infrastructure solutions at an exceptionally high level, the North American plastic pipe business delivered a record result. Raw material shortages and substantial price increases created a challenging situation in the procurement market. The situation was particularly challenging in the first quarter of the reporting year, when subcontractors reported force majeure events attributable to winter storms in Texas, and input materials were in short supply. In the second quarter, the situation remained tense on account of suppliers' low inventory levels and high demand from the market. However, thanks to our long-term delivery contracts, an optimized supply chain, and targeted inventory management, we successfully coped with this situation. The notably increased raw material costs could successfully been compensated.

Outlook for 2021

We expect to see a continuation of positive market trends in new build in the second half of the year to the advantage of our façade business. In the infrastructure segment, which experienced a particularly high level of demand in the first half of the year, we expect a continuation of current demand trends supported, among other factors, by infrastructure programs. Overall, we foresee a record full-year result for the North America Business Unit.

With regard to the planned acquisition of Meridian Brick, continuous progress has been achieved in constructive dialogue with the appropriate authorities. The closing of the transaction is expected in the third quarter of 2021.

2 nd Quarter of 2021

In the second quarter of 2021, Wienerberger achieved very satisfying results, with record levels reported by all business segments:

• › External revenues increased by 26% to € 1,069.6 million (2020: € 847.2 million)
• › EBITDA LFL grew significantly by 37% to € 201.2 million (2020: € 146.4 million), thus surpassing the pre-crisis level
• › Strong performance across all Business Units despite partly muted developments in the core markets

Wienerberger Group	18.5 200.6	155.8	+29

In the second quarter of 2021, all Business Units delivered a strong performance with very satisfying results, which even surpassed the pre-crisis level. This record result was attributable, above all, to organic growth thanks to innovative product solutions and the consistent implementation of our Self-help program.

Building and roof solutions benefited from solid demand in new build and strong renovation activities in the core markets. Thanks to excellent supply chain and margin management, the pipe business recorded exceptionally high sales volumes and significant growth. North America's second-quarter results were able to profit, above all from the Business Unit's strong plastic pipe business.

Wienerberger Building Solutions With external revenues of € 636.8 million (2020: € 514.0 million) in the second quarter of 2021, the Wienerberger Building Solutions Business Unit generated an EBITDA LFL of € 142.5 million (2020: € 100.5 million).

After a late start of the 2021 construction season due to unfavorable weather conditions, the second quarter was marked by consistently sound demand. The Western European markets benefited from intensive renovation activities and solid demand in new residential construction. Great Britain and Belgium, in particular, delivered substantial contributions to earnings. The situation in Austria was marked by very high demand in all product groups. We also observed growing demand in new build in our Eastern European markets, although the first quarter was affected by harsh winter weather. In some of our Eastern European core markets, demand in new residential construction remained muted and has not yet reached the pre-crisis level. In all our markets, the roofing business benefited from a persistently high level of renovation activity.

Wienerberger Piping Solutions The Wienerberger Piping Solutions Business Unit reported strong second-quarter growth. While external revenues increased by 32% to € 329.0 million (2020: € 249.6 million), EBITDA LFL grew by 13% to € 38.8 million (2020: € 34.3 million). As regards procurement, the environment remained challenging throughout the second quarter, but through proactive margin management we

largely succeeded in offsetting the effect of rising raw material costs. Thanks to our excellent supply chain management, we were able to guarantee product deliveries on schedule and at all times, thus positioning ourselves as a reliable partner for our customers. Our second-quarter performance was therefore marked by extraordinarily high sales volumes and strong demand for infrastructure and in-house solutions in all core markets.

Our Northern European markets delivered a solid performance. Western Europe benefited not only from continuing high demand in all product groups, but also from Covid-19-related catch-up effects. The strongest growth momentum was seen in the markets of Eastern Europe, which benefited from our strong market position and reported particularly high sales volumes. Excellent supply chain management and successful procurement initiatives enabled us to guarantee the availability of our products at all times.

North America With 24% external revenue growth to € 103.7 million (2020: € 83.5 million) and an increase in EBITDA LFL by 71% to € 20.0 million (2020: € 11.6 million), the North America Business Unit generated an excellent result in the reporting period, supported by strong performance in all product groups, especially in the plastic pipe business.

Activities in the USA and Canada benefited from a positive market environment in new residential construction and high demand for façade solutions. Utilization rates of plants in North America have been at a very high level.

The exceptionally strong result of the plastic pipe business was attributable to high demand for infrastructure solutions, on the one hand, and dynamic margin management, on the other hand, with significant raw material price increases being passed on to the market without delay.

Condensed Notes to the Interim Financial Statements

Accounting and valuation principles The interim financial report as of June 30, 2021 was prepared in accordance with the principles set forth in the International Financial Reporting Standards, Interim Financial Reporting (IAS 34). The major judgements and estimates used to prepare the consolidated financial statements for 2020 as well as the accounting and valuation methods in effect on December 31, 2020 remain unchanged, with the exception of the IFRSs that require

mandatory application as of January 1, 2021. The Interim Report should therefore be read in conjunction with the consolidated financial statements as at December 31, 2020.

All numbers in this interim financial report are expressed in thousands of euro, with only a few marked exceptions.

The following table provides an overview of the new standards and interpretations published by the IASB as of the balance sheet date:

1) Mandatory effective date according to European Union directive.

New and amended standards and interpretations published that were adopted by the EU

The amendments to IFRS 4 Insurance Contracts, published in June 2020, concern the prolongation of the temporary exemption from the application of IFRS 9. The amendments must be applied on a mandatory basis as of January 1, 2021, and have no impact on Wienerberger's financial statements.

In August 2020, the IASB published amendments of IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16. The secondphase amendments supplement the requirements of the first phase and concern the replacement of a given interest rate benchmark by another interest rate benchmark. The

amendments are to be applied on a mandatory basis as of January 1, 2021.

In May 2020 the IASB published clarifications on IAS 37 Provisions, Contingent Liabilities and Contingent Assets, IAS 16 Property, Plant and Equipment, IFRS 3 Business Combinations and the IFRS 2018-2020 improvement cycle. IAS 37 defines which costs can be taken into account in the case of an onerous contract. IAS 16 clarifies how the sale of products from the test phase of production equipment is to be recognized in the financial statements. IFRS 3 receives an update to the conceptual framework. These amendments have no impact on Wienerberger's financial statements.

New and amended standards and interpretations published, but not yet adopted by the EU

In March 2021, the Covid-19-related amendments to IFRS 16, which had been published in May 2020, were prolonged for one year. The amendments to IFRS 16 Leases provide for practical expedients for lessees in the accounting of rent concessions. For a limited period of time, lessees are exempted from assessing whether a Covid-19-related rent concession is a lease modification. This expedient is only applicable to payment due on or before June 30, 2022. Wienerberger did not make use of these practical expedients.

In May 2017 the IASB published IFRS 17 Insurance Contracts, a new standard which replaces IFRS 4 and clarifies the accounting treatment of insurance and reinsurance contracts. Given that Wienerberger holds neither insurance nor reinsurance contracts as an insurer, the new standard is of no relevance to the financial statements of the Group.

In January 2020 amendments to IAS 1 were published. These amendments introduce a more generally valid approach to the classification of liabilities as shortterm according to IAS 1, which is based on the contractual arrangements in effect as of the balance sheet date. The amendments are to be applied on a mandatory basis as of January 1, 2023.

Amendments to IAS 1 and IAS 8 were published in February 2021. The amendments to IAS 1 require companies to disclose their material accounting policy information rather than their significant accounting policies. The amendments to IAS 8 contain clarifications on changes in accounting estimates in order to improve the distinction from changes in accounting methods. The amendments are to be applied on a mandatory basis as of January 1, 2023.

In May 2021, amendments to IAS 12 were published. The amendments clarify how companies account for deferred taxes relating to assets and liabilities arising from a single transaction (such as leases). The amendments are to be applied on a mandatory basis as of January 1, 2023.

Consolidated companies The consolidated financial statements include all major domestic and foreign companies in which Wienerberger AG directly or indirectly holds the majority of shares. In accordance with IFRS 11, Schlagmann Poroton GmbH & Co KG, Silike keramika, spol. s.r.o. and TV Vanheede-Wienerberger are classified as joint ventures, because they are managed jointly with an equal partner. Consequently, these companies are accounted for at equity (50%). TONDACH BOSNA I HERCEGOVINA d.o.o., in which Wienerberger holds 80% of the shares, is subject to joint management on account of the distribution of voting rights and is accounted for at equity. Moreover, Wienerberger holds a 30% stake in Interbran Baustoff GmbH and Fornaci Giuliane S.r.l (in liquidation), which are also classified as a joint venture on account of its joint management.

Seasonality Due to the impact of weather conditions on construction activity, the sales volumes reported by Wienerberger for the first and last months of the year are lower than at mid-year. These seasonal fluctuations are reflected in the figures reported for the first and fourth quarters of the year, which generally are lower than those reported for the second and third quarters.

Wienerberger Hybrid Capital On 11/12/2020 the Managing Board decided to call the 2014 hybrid bond at the earliest possible date and to redeem the outstanding perpetual subordinated hybrid bond with a nominal value of TEUR 214,630 on 9/2/2021. As a result, the hybrid capital previously recognized in equity was reclassified to current financial liabilities on 31/12/2020. In the reporting period, the remaining hybrid bond with a nominal value of TEUR 214,630, plus a coupon of TEUR 10,732, was redeemed.

For the period prior to redemption, a coupon of TEUR 1,176, accrued on a pro-rata-temporis basis, was taken into account in the determination of earning per share. As a result, earning per share decreased by EUR 0.01.

Notes to the Consolidated Income Statement Group revenues amounted to TEUR 1,867,541 for the first six months of 2021 (2020: TEUR 1,641,535),

which is 14% higher than the comparable period of the previous year.

EBITDA amounted to TEUR 306,966 which is higher than the comparable prior year value of TEUR 261,861. EBIT amounted to TEUR 170,566 for the reporting period, compared to TEUR 19,711 in 2020.

As at June 30, 2021, Wienerberger held 2,881,910 treasury shares (31/12/2020: 2,922,168), which were deducted for the calculation of earnings per share. The weighted number of shares outstanding from January 1, 2021 to June 30, 2021 was 112,273,154. The number of shares issued amounted to 115,187,982 as at June 30, 2021.

In the reporting year, a dividend of EUR 0.60 per share on the issued capital of 115,187,982.00 EUR, that is EUR 69,112,789.20 minus a pro-rata amount for own

shares of EUR 1,753,300.80, i.e. EUR 67,359,488.40, was resolved upon and paid out.

For the first six months of 2021, depreciation in the amount of TEUR 23,673 (2020: TEUR 24,656) for rightof-use assets and TEUR 1,887 (2020: TEUR 2,009) for interest expenses for lease liabilities were taken into account in the Consolidated Income Statement.

The change in the weighted costs of capital (WACC), applied in the discounting of future cash flows in order to determine the value in use of the CGU groups, was deemed to be a triggering event for the performance of impairment tests. In the CGU group Pipes Pipelife East within the Wienerberger Piping Solutions segment, a value in use of approximately MEUR 231 was determined

as at 30/6/2021 by applying a WACC after tax of 9.27% (31/12/2020: 9.09%), which resulted in an impairment charge to total goodwill of TEUR 10,747.

Notes to the Consolidated Statement of

Comprehensive Income Currency translation differences of TEUR 33,229 (2020: TEUR -50,903) resulted, above all, from the British pound, the US dollar and the Czech koruna. After consideration of deferred taxes of TEUR -2,316 (2020: TEUR 2,932), a net amount of TEUR 30,913 (2020: TEUR -47,971) is shown in other comprehensive income. The hedging reserve changed equity by TEUR -1,580 (2020: TEUR 9,200). This amount includes deferred taxes of TEUR 527 (2020: TEUR -3,067). The measurement of defined pension plans and similar post-employment benefits resulted in actuarial gains of TEUR 8,836 (2020: TEUR -10,374). Deferred taxes included in this amount came to TEUR -1,455 (2020: TEUR 1,275). Profit after tax reported for the first six months of 2021 increased equity by TEUR 113,574 (2020: TEUR -23,582). Total comprehensive income after tax increased equity by TEUR 151,743 for the reporting period (2020: TEUR -72,727).

Notes to the Consolidated Statement of

Cash Flows Gross cash flow increased to TEUR 236,858 (2020: TEUR 187,807) primarily as a result of the Group's positive operating performance. Special write-downs of TEUR -10,515 (2020: TEUR 1,034) recognized in impairment charges to assets and other valuation effects primarily result from the shut-down of plants respectively production lines. In the prior period, the impairment tests performed according to IAS 36 resulted in an additional impairment charge to property, plant and equipment and intangible assets in the amount of TEUR -23,311. Other valuation effects include stock revaluation of TEUR -2,940 (2020: TEUR -3,471) and the valuation of financial assets of TEUR -6,798 (2020: TEUR 9,430).

Cash flow from operating activities amounted to TEUR 90,661 (2020: TEUR 34,607), i.e. TEUR 56,054 above the comparable value of the previous period, which was primarily due to an increase in gross cash flow.

Cash outflows of TEUR 82,045 (2020: TEUR 69,997) for investments in non-current assets (incl. financial assets) and acquisitions included TEUR 43,257 (2020: TEUR 46,084) of maintenance capex and TEUR 31,971 (2020: TEUR 21,873) for plant extensions, innovation and sustainability (special capex). For acquisitions and investments in financial assets TEUR 6,826 were spent (2020: TEUR 2,040).

Proceeds from the disposal of non-current assets totaled TEUR 15,469 (2020: TEUR 20,179) and included the sale of investment property.

Notes to the Consolidated Balance Sheet Maintenance and special capex for the first six months of 2021 (excl. acquisitions) increased non-current assets by TEUR 75,228 (2020: TEUR 67,957). Net debt rose by TEUR 63,978 over the level of December 31, 2020 to TEUR 946,123 due to the seasonal increase in working capital.

Property, plant and equipment recognized in the Consolidated Balance Sheet as at 30/6/2021 include rightof-use assets according to IFRS 16 of TEUR 219,703 (31/12/2020: TEUR 208,797); financial liabilities include lease liabilities of TEUR 227,964 (31/12/2020: TEUR 217,099).

Commitments for the purchase of property, plant and equipment totaled TEUR 40,897 as at the balance sheet date (31/12/2020: TEUR 24,743).

On account of the expiry of guarantees for third parties, contingent liabilities and guarantees declined to TEUR 14,069 (31/12/2020: TEUR 19,527).

The valuation of financial instruments classified under level 3 is shown in the following table:

Investments in subsidiaries and other investments constitute financial instruments to be held in the long term. According to IFRS 9, equity instruments are recognized at their fair value. As the measurement of these financial instruments is based on measurement parameters not observable in the market, they are allocated to level 3 of the fair value hierarchy. The fair values are determined by a procedure based on the income approach as the present values of the total of future cash inflows, with the weighted average cost of capital after tax derived from external sources in accordance with recognized mathematical procedures.

The fair value of shares in funds, corporate bonds, stocks and the bonds issued by Wienerberger was determined on the basis of market prices (level 1). Other securities include short-term investments of liquidity, which

are measured on the basis of interest rates observable in the market and therefore classified as level 2 instruments. Reinsurance for pension obligations, which must not be netted against the pension provision, are allocated mainly to level 3 of the valuation hierarchy and reported under other securities.

Derivatives were valued with net present value methods based on input factors observable in the market, e.g. yield curves and foreign exchange parities (level 2).

The fair value of other non-current receivables and non-quoted financial liabilities carried at amortized cost was also determined with net present value methods based on current yield curves (level 2). Fair value adjustments to financial liabilities are made by modifying the counterparty risk.

Risk Report Throughout the Group, Wienerberger focuses on the early identification and active management of risks in its operating environment. To this end, regular surveys are being performed among the Managing Board as well as the Business Unit managers and Corporate Function heads in charge in order to update the existing risk catalogue and to identify new risks. In this process, strategic and operational risks along the entire value chain are being identified and their impact on cash flow is differentiated based on a medium-term (up to five years) and a longterm (six to ten years) time horizon.

The major risks identified include competition from substitution products, such as concrete, steel, wood, limestone, glass or aluminum, and the related pressure on prices. Management sees further relevant risks in higher input costs and volatile raw material prices for plastics. We aim to minimize these risks by means of our strong position as a quality leader and through the development of premium products. These developments primarily concern improvements in terms of construction physics and the cost-efficiency of our products.

Wienerberger regularly monitors the risks in its operating environment as part of its corporate risk management program and takes appropriate actions to counter these risks. The development of the construction industry and major indicators of the demand for building materials are watched closely to permit the timely adjustment of capacity in the plant network to reflect changing market conditions. The price levels on local markets are also monitored regularly, and pricing strategies are adjusted, if necessary. Wienerberger counters the risk of rising input costs by establishing fixed procurement prices at an early point in time and by concluding long-term supply contracts. The risks associated with rising energy costs are reduced through the Group's hedging strategy. The risks expected by Wienerberger during the remaining months of this year are linked to higher input costs, uncertainty over further developments in the construction industry and continued pressure on prices in individual markets. To counter the risk of interruptions of operations due to Covid-19 infections, Wienerberger has introduced stricter hygiene measures and shift work in its plants.

The plastic pipe business is substantially influenced by the development of raw material prices. Synthetic polymers account for a major part of the production costs for plastic pipes. The volatility of raw material prices has increased considerably in recent years. Strong fluctuations within individual months require flexible pricing to limit the effects of these price changes respectively pass them on to the market. Fast price management is a decisive factor for the sustainable protection of earnings. In addition to the price risk, this business is exposed to a raw material supply risk. Possible shortages on the raw materials market are countered by extensive measures in procurement, production and sales as well as price management.

In addition Wienerberger is also exposed to an energy supply risk, in particular with respect to natural gas and electricity. Any disruption of energy supplies would invariably lead to the standstill of production and could therefore have a negative effect on operating profit if demand cannot be met from inventories.

Securing Wienerberger's cash position is a crucial part of the corporate strategy. Besides cash and cash equivalents of MEUR 450, committed but undrawn credit lines of MEUR 371 are shown as at 30/6/2021, which enable Wienerberger to cover operational business risks as well as any liabilities falling due.

Wienerberger is exposed to legal risks in connection with increasingly strict environmental, health and safety regulations, which could result in the Group being liable for penalties or claims to compensation for damages in the event of non-compliance.

In 2014, Wienerberger was granted carbon leakage status for its European brick operations. Based on a further qualitative evaluation performed in 2018, the brick industry has been included in the new carbon leakage list for the fourth trading period. This means that Wienerberger will enjoy carbon leakage status and therefore be allocated the major part of the CO² certificates required free of charge.

Related party transactions The following companies and persons are considered to be related parties of Wienerberger: the members of the Supervisory and Managing Boards as well as their close relatives, associated companies, joint ventures and nonconsolidated subsidiaries of Wienerberger AG as well as the ANC Private Foundation and its subsidiaries. Transactions with companies in which members of the Supervisory Board of Wienerberger AG are active are generally conducted on arm's length conditions.

The ANC Private Foundation operates landfill activities in Austria that were transferred by Wienerberger AG in 2001 and owns a limited amount of assets (in particular real estate and securities). The managing board of the ANC Private Foundation consists of three members, two of whom are part of the Wienerberger top management. This allows Wienerberger to exercise control over the foundation. In accordance with IFRS 10, the ANC Private Foundation cannot be consolidated because the shareholders of Wienerberger AG, and not the company itself, are entitled to the variable cash flows from the foundation. The total assets of ANC Private Foundation amounted to TEUR 32,249 as of June 30, 2021 (31/12/2020: TEUR 31,433) and consist primarily of land and buildings totaling TEUR 7,195 (31/12/2020: TEUR 8,008) and securities and liquid funds of TEUR 21,208 (31/12/2020: TEUR 17,519). The foundation had provisions of TEUR 11,057 (31/12/2020: TEUR 8,295) and no financial liabilities as of June 30, 2021.

Wienerberger AG and its subsidiaries finance associates, joint ventures and non-consolidated subsidiaries through loans granted at ordinary market conditions. The outstanding loan receivables due from joint ventures amounted to TEUR 16,890 as of June 30, 2021 (31/12/2020: TEUR 15,545), while the comparable amount for non-consolidated subsidiaries was TEUR 5,635 (31/12/2020: TEUR 5,587). Revenues in the amount of TEUR 2,254 (2020: TEUR 1,896) were recognized with joint ventures during the first six months of the year.

Significant events after the balance sheet date On 09/7/2021, the acquisition of 100% of the shares in FloPlast in Great Britain and Cork Plastics in Ireland was announced.

On 21/7/2021, the Managing Board decided to evaluate the sale of up to 2,500,000 treasury shares, i.e. of up to 2.2% of the share capital of the Company, to institutional investors by way of an accelerated private placement procedure, excluding the subscription right of current shareholders.

Waiver of Audit Review This interim report by Wienerberger AG was neither audited nor reviewed by a certified public accountant.
