‌MASTERPLAST

Founded in 1997, Masterplast Group is the largest Hungarian-owned building materials manufacturing company in the Central European region. It has a direct market presence in 10 European countries through its subsidiaries and is present in most European countries through its export partners. It has a strong position in the market for façade insulation, roof insulation and dry construction systems.

The Group primarily relies on production at its ISO and TÜV certified production sites in Hungary, Serbia and Germany and through strategic manufacturing partnerships. The company's strategic goal is to ensure the successful development of the modular business division as soon as possible. Due to the growing demand for fibre insulation materials, the company's focus in 2023 was on the establishment of glass wool insulation material plant to meet the needs of the Hungarian and Central and Eastern European markets.

Masterplast provides competitive business services to its partners through a well-established customer-oriented sales system, continuous quality control of manufactured and distributed products, a stable product supply background and flexible logistics solutions.



‌SUMMARY In the first quarter of 2026, Masterplast achieved consolidated revenue of EUR 57,4 million, representing the third-highest quarterly turnover in the Company's history and exceeding the same period of the previous year by 72%. The outstanding performance continued to be significantly supported by the strong sales of CES (Certified Energy Savings) and the related products, while sales growth was also experienced across the majority of product groups and markets. As a result of the remarkable turnover, higher capacity utilisation and improving operational efficiency, the Group's EBITDA increased to EUR 5,1 million, while profit after tax closed at a profit of EUR 1,9 million, representing an improvement of more than EUR 4 million compared to the previous year. The Middle Eastern conflict that escalated at the end of February caused significant disruptions and price increases in global raw material markets, to which the Company responded by relying on its diversified supplier structure, treating security of supply and maintaining production continuity as primary objectives. Thanks to the existing inventory levels and the broad raw material supplier base, the drastic price increases are incorporated into production costs only gradually, projecting strong profitability for the second quarter. The broad manufacturing portfolio, improving operational efficiency and the growing demand for energy efficiency solutions provide a stable basis for the sustainable strengthening of the Company's earnings-generating capability.

  • In the first quarter of 2026, the European construction industry environment continued to show a mixed picture. Following the monetary easing measures of 2024-2025, the eurozone interest rate environment stabilised at a lower level, while housing market activity developed differently across countries. Energy efficiency regulations and support programmes continued to provide a supportive framework for the renovation market, where a slow but gradual recovery had been observable in recent quarters. The Hungarian market for Certified Energy Savings (CES) remained exceptionally active in the first quarter of 2026, which played a decisive role in the Company's performance. During the quarter, the March escalation of the Middle Eastern conflict caused new supply risks due to disruptions in energy and petrochemical transportation. The explosive increase in raw material prices immediately appeared in finished product prices and resulted in advance purchases in the market.

  • Masterplast achieved near-record revenue of EUR 57,4 million in the first quarter of 2026, representing a 72% increase compared to the same period of the previous year. In addition to the outstanding turnover of product groups related to CES transactions and the Hungarian market, most other product groups and markets also achieved revenue growth. The postponed purchases resulting from the unusually cold winter months, together with the impact of price increases, led to stronger-than-usual sales performance in March.

  • The utilisation of manufacturing capacities was higher in all production units during the reporting quarter compared to the base period. Thanks to the improved utilisation rates, the Company's production units operated more cost-efficiently.

  • The Company's closing headcount was 1 170 employees, exceeding the base period headcount of 1 111 employees by 5.3%. Personnel expenses during the quarter exceeded the same period of the previous year by 19%. The increase was attributable to wage increases as well as performance bonuses and shift allowances related to the favourable sales performance and higher capacity utilisation.

  • The Group's EBITDA amounted to EUR 5 143 thousand in Q1 2026, corresponding to an EBITDA margin of 9.0%, and more than five times the EBITDA result of EUR 973 thousand achieved in the first quarter of 2025.

  • Depreciation and amortisation decreased by 7% compared to the base period, primarily due to the shutdown of the Italian EPS production plant and the impact of healthcare machinery reclassified as assets held for sale.

  • Taking depreciation into account, the Company's EBIT for Q1 2026 amounted to a profit of EUR 3 462 thousand, representing an improvement of EUR 4 297 thousand compared to the base period.

  • The Company's net interest result improved, while exchange rate movements had a neutral impact on the Company's financial result, in contrast to the base period, when a higher unrealised loss was recognised under financial operations.

  • The result of associates showed a loss of approximately EUR 663 thousand during the reporting quarter, primarily due to additional operating costs related to the ramp-up phase of the glass wool plant in Szerencs. The intensity of this negative impact is expected to decrease materially in the upcoming periods. Glass wool production volumes increased significantly, while operational efficiency indicators are continuously improving. Together with its co-owner, Selena FM S.A. of Poland, the Company is preparing further developments in order to serve regional market demand more efficiently, improve production efficiency and increase the share of higher value-added products, while also examining related subsidy opportunities.

  • In the first quarter, the Company achieved a profit after tax of EUR 1 907 thousand, compared to a loss of EUR 2 194 thousand recorded in the same period of the previous year, representing an earnings improvement of more than EUR 4 million.

  • Parallel with the higher revenue level, trade receivables increased by 35%, while inventory value exceeded the

    level of one year earlier by 23%, which reduced the Group's cash position.

  • Thanks to the existing inventory levels and diversified supplier background, the increased raw material prices are incorporated into production costs only gradually; therefore, the Company continues to expect strong profitability in the second quarter. The Company believes that raw material supply difficulties will ease in the near future and that the Iranian geopolitical conflict will gradually stabilise. Meanwhile, regulatory demand for energy efficiency continues to increase across Europe, which may provide sustained demand for the Company's products.

‌BUSINESS PROSPECTS

The escalation of the Middle Eastern conflict and the disruption of traffic through the Strait of Hormuz have caused considerable uncertainty in global raw material markets recently. The situation particularly affects plastic raw materials based on crude oil derivatives and special chemical additives. The Company's focus is on maintaining security of supply and ensuring production continuity, supported by its broad procurement relationships. Thanks to existing inventories and a diversified supplier base, the increased raw material prices are incorporated into production costs only gradually. This represents a competitive advantage for Masterplast, and therefore the Company expects strong profitability in the second quarter. The outlook for the coming period may be determined primarily by the extent to which international chemical supply chains are affected and the pace at which market equilibrium can be restored. At the same time, the current market turbulence may further strengthen the tightening energy efficiency regulatory environment, which supports structurally driven demand for the Company's products across Europe in the medium and long term.

As part of the "Fit for 55" climate policy package, in 2024 the European Union revised and strengthened the Energy Performance of Buildings Directive (EPBD), which aims to accelerate the decarbonisation of the building stock and achieve a substantial reduction in energy use. The Directive serves the objective of reaching climate neutrality by 2050 and requires Member States to prepare national renovation plans, increase the renovation rate and gradually modernise the building stock.

The effects of this regulatory and financing environment are also emerging in Hungary, the Company's largest market. Housing construction and modernisation activity is currently supported by several government incentives, including the Home Start Programme, the Housing Capital Programme and ongoing building insulation programmes. Based on market expectations, the change of government may provide additional momentum to the construction industry, primarily through the broader and faster drawdown of EU funds and through the new cabinet's programmes aimed at stimulating construction industry and energy efficiency investments. The "Wekerle Sándor Rental Housing Construction and Home Development Programme" aims to expand affordable housing and improve the energy

efficiency of the housing stock. According to the objective of the "Family Energy Programme", up to 100 thousand

dwellings per year may undergo energy renovation in Hungary.

In the market for Certified Energy Savings (CES), the robust demand seen in previous months is expected to moderate significantly for the remainder of 2026, but the Energy Efficiency Obligation Scheme (EEOS) continues to provide opportunities for the Company as a building materials manufacturer in the medium and long term.

Due to the significant increase in plastic raw material prices, the Company suspended its CES-based Hungarocell Renovation Programme in April 2026, as its operation under the changed market environment was no longer economically sustainable. At the same time, given the moderating demand in the CES market, the decision is not expected to have any material adverse impact on the Company's revenue and profitability.



Masterplast's innovative modular construction business division, based on factory prefabrication, is excellently aligned with programmes intended to promote affordable housing. The technology requires minimal live labour, provides standardised quality and enables rapid execution, all with low environmental impact. It offers a solution both for affordable housing and for the challenges posed by the shortage of skilled labour. The development of the modular building element manufacturing business is at an advanced stage; several family houses built using modular technology have already been handed over, and the development of apartment buildings has also commenced.

As a well-established player in the Ukrainian construction industry, the reconstruction of Ukraine may represent significant business potential for the Company in the period following a potential ceasefire agreement.

In recent years, the Company has implemented substantial manufacturing development investments. It has significantly increased its capacities in fibreglass mesh and diffusion roofing membrane production, enabling the Group to serve the market for premium-category products with the highest quality requirements. Its EPS, XPS and now operating glass wool production units enable Masterplast to develop into a thermal insulation material

The new glass wool factory in Szerencs is already producing

manufacturer with significant production and market positions in both plastic-based and mineral insulation materials. The recently optimised, broad manufacturing portfolio, together with the structurally supported market demand outlined above, provides a stable basis for the Company to further strengthen its earnings-generating capacity in the coming years.





‌Industrial environment

The external economic and industrial environment has a significant effect on the production and sale of the insulation and other construction materials, which are the main activities of the Masterplast. While the sale of the constructional and accessories products is mainly in relation with the new buildings market, the insulation related materials (primarily the heat insulation) depend on both the new building and home renovation markets.

In the first quarter of 2026, the European construction industry environment continued to show a mixed picture. Following the monetary easing measures of 2024-2025, the eurozone interest rate environment stabilised at a lower level, while the European Central Bank left benchmark interest rates unchanged in February and March 2026. Residential mortgage lending and housing market activity developed differently across countries. Energy efficiency regulations and incentive programmes continued to provide a supportive framework for the renovation market, where gradual recovery had been observable in recent quarters. The escalation of the Middle Eastern conflict at the end of February created new cost and supply risks for European industry: disruptions in energy and petrochemical transportation through the Strait of Hormuz triggered a rapid increase in energy prices as well as price increases in the plastics and polymer markets. The impact became visible already in March, resulting in advance purchases.

In Hungary, based on the monthly construction industry data published so far, no clear recovery emerged in overall construction output during the first quarter of 2026. According to the Hungarian Central Statistical Office (KSH), in February 2026 the volume of construction industry output was 0.4% lower year-on-year according to both raw and working-day-adjusted data, while seasonally and working-day-adjusted output exceeded the January level by 4.9%. In the first two months of the year, the volume of construction industry output was 5.7% lower than in the corresponding period of 2025, while building construction increased by 2.2% year-on-year in February. Housing construction data, however, indicated strengthening future activity: in the first quarter of 2026, 2,821 new homes were completed, exceeding the same period of the previous year by 4.3%, while the number of dwellings to be built based on issued building permits and simple notifications increased by 64% to 9,291. Government support schemes may continue to support demand and the renovation market: under the Home Start Programme, fixed-rate housing loans at 3% up to HUF 50 million are available for purchase or construction, while the Rural Home Renovation Programme provides non-refundable support of up to HUF 3 million for eligible residents of smaller settlements. EEOS/CES market activity remained exceptionally strong in the first quarter of 2026.

In Poland, housing construction indicators showed a mixed picture in the first quarter of 2026. According to Statistics Poland, 1.4% fewer dwellings were completed in January-March than in the corresponding period of 2025, while the number of building permits issued for new dwellings reached 67.5 thousand, representing a 7.4% year-on-year increase. Construction industry output data indicated fluctuations within the quarter: Eurostat reported a 9.0% monthly and 11.0% annual decline in Poland in January, while in February it reported a 3.7% monthly and 13.7% annual decrease. According to the March statistical release in Poland, seasonally adjusted construction and assembly production was 2.1% lower than in the previous month; therefore, no clear positive turnaround can be established for the quarter as a whole.

In Romania, the number of permits issued for residential buildings decreased in the first quarter of 2026, while February production data showed a more favourable picture. According to the Romanian National Institute of Statistics (INS), building permits were issued for 7,266 residential buildings in the first quarter of 2026, representing a 4.8% decrease compared to the corresponding period of 2025. At the same time, 3,112 residential building permits were issued in March, representing a 30.4% increase compared to February and a 0.5% increase compared to March 2025. In February, Eurostat reported outstanding growth in Romanian construction industry output among EU member states, with an 8.7% monthly increase and a 15.6% annual increase, although this alone cannot be regarded as a full-quarter trend.

In Serbia, no aggregated construction industry performance data for the full quarter were available for the first quarter of 2026; therefore, this section relies only on the published monthly permitting data. According to the Statistical Office

of the Republic of Serbia, 1,805 building permits were issued in February 2026, representing a 0.7% decrease compared to February 2025.

In Germany, construction industry order and sentiment data did not show a uniform picture in the first quarter of 2026. According to the Federal Statistical Office of Germany (Destatis), the order backlog of the main construction industry increased by 9.1% year-on-year in February 2026, within which building construction orders decreased by 5.4%, while civil engineering orders increased by 25.8%. According to the February residential construction survey of the ifo Institute (Leibniz Institute for Economic Research at the University of Munich), the business climate improved, but order conditions in the sector remained weak: 48.0% of residential construction companies complained about insufficient orders, while the proportion of companies reporting project cancellations was 11.3%.

In Ukraine, the wartime environment continued to determine construction industry and reconstruction prospects during the first quarter of 2026. According to the updated damage and needs assessment published in February by the World Bank, the European Commission, the United Nations and the Ukrainian government, Ukraine's recovery and reconstruction needs increased to nearly USD 588 billion for the 2026-2035 period. Recovery priorities for 2026 included public investment and essential recovery programmes exceeding USD 15 billion, including financing of destroyed housing, demining activities and economic support programmes affecting multiple sectors. According to first-quarter macroeconomic data published by Reuters, Ukraine's GDP declined by 0.5% year-on-year in the first quarter of 2026, burdened in part by Russian air strikes targeting infrastructure, particularly the energy sector.

In the smaller Slovak and Croatian markets, different trends were observable during the first quarter of 2026 based on the available data. In Slovakia, according to the statistical office, construction industry output decreased by 2.0% year-on-year in January, while in February it increased by 8.2%, linked to improving domestic construction activity, including road and railway construction works. In Croatia, according to February data from the Croatian Bureau of Statistics (DZS), the volume of construction works increased by 3.4% year-on-year on a working-day-adjusted basis, while the number of issued building permits in February totalled 722, representing a 25.5% annual decrease.

Masterplast's sales revenue in the first quarter exceeded the base quarter value by 72%, thereby reaching the third-highest quarterly sales revenue in its history.

The Thermal insulation system product group continued to account for the largest share of revenue (28%), showing an 11% increase compared to the same period of the previous year. The main driver of growth was the increase in the turnover of own-produced EPS products, while the turnover of also own-produced fibreglass mesh increased as well.

The turnover of the Roofing foils and accessories product group increased by 26%, mainly due to the sales of own-produced roofing foils.

In the case of the Heat, sound and water insulation materials group, outstanding turnover growth was recorded. Revenue from Masterplast's own-produced XPS products also increased significantly, while the sales of partly own-produced glass wool exceeded the level of one year earlier by more than six times. The increasing sales volumes of the above-mentioned glass wool are increasingly supplied by the glass wool plant in Szerencs.

The turnover of the Dry construction systems product group expanded marginally compared to the same period of the previous year. Revenue from Building industry accessories remained at the base level.

The turnover of the Industrial applications product group increased by slightly more than three times. Within this product group, the turnover performance of own-produced healthcare industry raw materials decreased, while revenue from other raw material trading activities improved compared to the previous year's base. The sale of the limited-transferability proprietary right (the so-called CES) is also recognised here, which generated significant revenue for the product group.

The breakdown of sales by country shows the revenue realized in countries where Masterplast has its own subsidiaries, regardless of which subsidiary made the sale in the territory of the given country. Turnover in countries without subsidiaries are reported as Exports.

The Hungarian market achieved exceptionally strong growth. Revenue increased across all product groups, while sales of CES and products related to CES programmes played a decisive role in the growth. The Company also launched its own façade thermal insulation discount programme and participated together with its insulation partners in the attic ceiling programme also available on the market. In connection with these programmes, a limited-transferability proprietary right is generated as a result of the energy savings achieved, the so-called Certified Energy Savings (CES). CES certified directly or indirectly through Masterplast partners are sold within the framework of the EEOS system to parties entitled to purchase CES. These sales also contributed significantly to the 144% turnover growth achieved in the Hungarian market.

In the Export region, the Company achieved 11% growth, mainly thanks to the strong performance of roofing foil products.

In Poland, the Company achieved 15% revenue growth in the first quarter, further strengthening the country's position as the Group's third-largest market. Sales of fibreglass mesh and roofing foil products expanded significantly in the region.

In the Romanian market, roofing foil sales increased, while revenue declined in all other product groups. The 49% revenue growth reported for the Romanian market was mostly attributable to property sales. In Serbia, the 9% turnover growth was driven by the strong performance of the Thermal insulation system product group and XPS products.

In Germany, revenue decreased by 1% in the reporting quarter, mainly due to weaker sales performance in the roofing foil product group. Despite the war situation, the Ukrainian market stably maintained the turnover level realised in the same period of the previous year. Roofing foil products also performed well here, while revenue decreased in the

Dry construction system and Thermal insulation system product groups. In Italy, the Company's turnover increased by 28% during the quarter. Fibreglass mesh sales increased significantly there, while EPS sales declined in connection with the closure of the local EPS plant.

The Company also achieved double-digit growth in its smallest markets, Slovakia, Croatia and North Macedonia, during the first quarter.

Turnover increased in almost all product groups and regions during the reporting quarter. Growth was not experienced exclusively in product groups and markets related to CES. All of this contributed to the efficient utilisation of the

The Group's net sales revenue amounted to EUR 57 416 thousand in the first quarter of 2026, representing a 72% increase compared to the base period.

The utilisation of manufacturing capacities significantly exceeded the level of one year earlier at all active production sites. The performance and profitability of the nonwoven (roofing foil base material) production units located in Aschersleben and Hungary increased substantially compared to the base period. The ramp-up of the XPS production unit is ongoing and its profitability has also improved.

The value of cost of materials and services - also taking into account the change in inventories of own production -

exceeded the base-year level by 71% in the first quarter. A higher increase was observed in purchased services, while

the increase in raw material costs and other material-type expenses, including energy costs, developed at a more moderate pace.

The Company's closing headcount was 1 170 employees, exceeding the base period headcount of 1 111 employees by 5.3%. Personnel expenses during the quarter exceeded the same period of the previous year by 19%. The increase was attributable to wage increases as well as performance bonuses and shift allowances related to the favourable sales performance and higher capacity utilisation.

Depreciation and amortisation decreased by 7% compared to the base period, primarily due to the shutdown of the Italian EPS production plant and the impact of healthcare machinery reclassified as assets held for sale.

Under Other operating income (expenses), Masterplast recognised a profit of EUR 404 thousand, compared to a profit of EUR 332 thousand in the base period. Other operating result includes grant income released proportionately to depreciation in relation to previous investments. Grant income decreased slightly, while the reversal of inventory impairment improved the current year's result.

The Group's operational EBITDA amounted to EUR 5 143 thousand in Q1 2026, corresponding to an EBITDA margin of 9.0%, and more than five times the EBITDA result of EUR 973 thousand achieved in the first quarter of 2025. Taking depreciation into account, the Company's EBIT for Q1 2026 amounted to a profit of EUR 3 462 thousand, representing an improvement of EUR 4 297 thousand compared to the base period.

The Company's interest income increased, while interest expenses decreased. Overall, the net interest result closed with a loss EUR 135 thousand lower than in the base period. Exchange rate movements had only a moderate impact on the Company's financial result in the reporting year. The Group purchases a significant portion of its products mainly in EUR and USD, while sales are realised in local currencies; therefore, exchange rate movements influence the Group's result. The currencies of most countries are linked to the euro, therefore EUR/USD movements affect exchange rate results in the case of USD-based procurements. Under other financial income/expenses, the Company recognised a loss of EUR 41 thousand, mostly unrealised, compared to a loss of EUR 712 thousand one year earlier. Overall, the Company recognised a financial loss of EUR 650 thousand during the quarter, representing a loss EUR 806 thousand lower than one year earlier.

The result of associates represented a loss of approximately EUR 663 thousand during the reporting quarter, primarily due to operational challenges related to the ramp-up phase of the glass wool plant in Szerencs. The intensity of these effects is expected to decrease materially in the upcoming periods.

In the first quarter, the Company achieved a profit after tax of EUR 1 907 thousand, compared to a loss of EUR 2 194 thousand realised in the same period of the previous year.

The Group's total assets amounted to EUR 198 587 thousand at the end of March 2026, which was EUR 11 125

thousand, or 5%, lower than the level recorded one year earlier.

The value of non-current assets amounted to EUR 109 838 thousand at the end of the first quarter of 2026, which was EUR 21 580 thousand lower than the base-period value. The decrease in property, plant and equipment was primarily attributable to impairment effects related to the shutdown of the Italian EPS production plant, as well as the reclassification of certain machinery of the healthcare division into assets held for sale. The decrease in the value of investments in associates was mainly caused by the previously recognised impairment related to the investment in the rock wool plant project, namely MIP Ltd.

The value of current assets increased to EUR 88 749 thousand, exceeding the level of the corresponding period of the previous year by 13%. Inventories increased by 23% to EUR 45 886 thousand, mainly related to the higher production and sales volumes. At the end of the period, trade receivables amounted to EUR 24 208 thousand, representing a 35% increase compared to the corresponding period of the previous year, in line with the significantly increasing revenue. The value of other current assets also increased, primarily as a result of higher receivables related to associates. Cash and cash equivalents decreased to EUR 3 461 thousand, mainly influenced by higher working capital requirements, the increase in inventory levels and measures aimed at maintaining security of supply.

The value of non-current liabilities decreased to EUR 70 216 thousand, within which liabilities related to bond issuance amounted to EUR 27 198 thousand. The decrease in the loan and bond portfolio was in line with the fulfilment of the Company's repayment obligations. Current liabilities increased to EUR 64 378 thousand, primarily due to the higher level of trade payables and the increase in tax liabilities related to growing business activity. Trade payables reached EUR 21 472 thousand, associated with higher raw material purchases and the increased inventory level.

‌Investigations against Masterplast

As part of the transfer price investigation launched at the Romanian subsidiary of the Company, the Romanian Tax Authorities identified a tax deficit of EUR 454 638 (RON 2 318 107) in 2020 for the financial years 2014-2018. The Company has appealed because of the finding with the assistance of experts thus the proceedings are still ongoing. In order to avoid possible future tax fines, the Company has paid the full amount to the tax authorities in year 2020. The Group is of the opinion that the proceedings are not expected to have a material impact on the financial position or performance of the Company.

In connection with the previous work accident at Masterplast Medical Kft., an investigation is underway by the Székesfehérvár Police Department. The condition of the injured employee has improved significantly since the accident, and the Company remains confident that this positive development will continue.
