Improved operating margin in Ventilation Systems, but challenging quarter for Profile Systems

Ventilation Systems showed stable sales in the first quarter of the year, and the operating margin improved thanks to efficiency measures. The Group's operating profit was impacted by a challenging quarter in Profile Systems, due to a subdued project market and harsh winter conditions.

Q1 2026

A word from the CEO

During the first quarter, Ventilation Systems reported stable sales and improved operating margin compared to the previous year. The smaller business area Profile Systems weighed on the Group's result, primarily due to a weak project market.

Organic growth for Ventilation Systems in the Nordics

Sales for Ventilation Systems were stable despite continued challenging market conditions in many markets. The operating margin for the business area increased in the quarter to 9.2 percent from 9.0 percent, thanks to efficiency measures. On

a positive note, the recovery in the Nordics continued where ventilation sales showed organic growth in the quarter thanks to proactive project sales. Also, in important countries like Italy and the UK, sales and results were strong, while the markets in Germany and the Netherlands remained weak.

Challenging quarter for Profile Systems

Profile Systems delivers roof and wall solutions, leading to large seasonal variations. A harsh winter in the Nordics impacted sales negatively during the first two months of the year. We also see a weak project market and profitability under pressure in the only remaining Profile Systems operation in Eastern Europe, located in Romania. As previously communicated, the company is planned to be divested, and our assessment is that it will happen during the second quarter. This completes the business area's exit from Eastern Europe.



Given the structural measures implemented and a stabilisation of volumes, our assessment is that Profile Systems has the conditions in place to gradually improve profitability towards the Group's financial targets.

Furthermore, the sandwich panel business continued to be affected by the impacts of the relocation carried out during the previous winter. Production and sales have not yet returned

to the same levels as prior to the relocation. The low sales volume for the business area led to a negative result for the quarter. A potential turning point could be seen in March, with some sales growth and improved profitability.

Given the structural measures implemented and a stabilisation of volumes, our assessment is that Profile Systems has the conditions in place to gradually improve profitability towards the Group's financial targets. The business has now been focused on the Scandinavian markets, where the organisation



is being reviewed to increase business focus and ensure clear accountability for results. Further structural measures are continuously evaluated.



Our stated objective is to fully compensate for these higher costs through price adjustments.

Price adjustments to compensate higher raw material prices Lindab Group does not have any operations in the Middle East, however the conflict around the Persian Gulf affects us through higher raw material prices and increased transport costs. Our stated objective is to fully compensate for these higher costs through price adjustments.

Over the coming year, we anticipate the European ventilation market to grow slightly, from low levels. For Profile Systems, our assessment is a stabilisation in the market during 2026.

To conclude, Lindab Group has strong prospects of benefitting from a growing demand for energy-efficient ventilation, contributing to sustainable buildings and a healthy indoor climate. With a strong product portfolio, well-invested production facilities and a highly competent sales force we stand well positioned to meet increased demand in turbulent times.

Sales and market

Net sales for the Group amounted to SEK 3,003 m (3,214) during the quarter, a decline of 7 percent compared with the corresponding quarter previous year. Sales growth in comparable units amounted to -3 percent, while currency effects had a negative impact of -4 percent. The net effect from acquisitions and divestments was neutral.

The year started softly, primarily due to cold weather conditions in January and February, which negatively affected construction activity in several of the Group's markets. These weather-related conditions led to project delays, limited activity at construction sites and temporarily lower demand at the beginning of the period.

During the latter part of the quarter, activity levels gradually improved. However, this improvement was not sufficient to fully offset the weak start to the year.

During the quarter, Lindab Group continued to implement efficiency measures, including initiatives within procurement and the simplification of the legal structure. In the US, four legal entities within Vicon were merged into a single entity, with the aim of reducing complexity and strengthening operational efficiency.

Profit

Operating profit for the quarter amounted to SEK 188 m (228), corresponding to an operating margin of 6.3 percent (7.1). The decline compared with the previous year is mainly explained by lower volumes during the first two months of the quarter. Efficiency measures implemented mitigated the impact on earnings, but were not sufficient to fully compensate for the volume decline. Profit for the quarter amounted to SEK 108 m

(145). Earnings per share before and after dilution amounted to SEK 1.41 (1.89).

1) No one-off items and restructuring costs were reported in the Ventilation Systems segment during the quarter January-March 2026, in line with the corresponding period previous year. See page 21 for reconciliation.

Sales and market

Net sales in Ventilation Systems amounted to SEK 2,506 m (2,600) in the first quarter, a decrease of 4 percent compared with the corresponding quarter previous year. Sales growth for comparable units amounted to -1 percent and currency effects had an impact of -5 percent. The net effect from acquisitions and divestments contributed positively by 2 percent.

Sales development in Ventilation Systems was slightly weaker than in the corresponding quarter previous year, mainly due to continued subdued construction activity in several European markets. Operations were negatively affected by cold weather during the quarter, including in countries that usually experience milder winters, resulting in lower construction activity and project delays.

The Nordic markets performed well and reported positive organic sales growth during the quarter, with contributions mainly from Sweden, Denmark and Finland. Development in Western Europe remained weak, with markets such as Germany and the Netherlands reporting negative organic growth due

to low demand in new construction. At the same time, positive organic growth was recorded in countries such as the UK and Italy.

Developments in Central Europe were mixed. Several markets showed improved trends towards the end of the quarter, although total organic sales remained below the level of the previous year.

Profit

Operating profit for Ventilation Systems amounted to SEK 230 m (234), corresponding to an operating margin of 9.2 percent (9.0). The stable margin development is primarily explained by an improved gross margin, continued effects from efficiency measures and a gradual recovery in the Swedish market.

Acquisitions completed at the end of 2024 and during 2025 have been well integrated into the operations and develop according to plan. Overall, this has contributed positively to the earnings and margin development of Ventilation Systems during the period.

1) No one-off items and restructuring costs were reported in the Profile Systems segment during the period January-March 2026, in line with the corresponding period previous year. See page 21 for reconciliation.

Sales and market

Net sales in Profile Systems amounted to SEK 497 m (614) in the first quarter, corresponding to a decrease of 19 percent. Organic growth was -10 percent, currency effects amounted to -2 percent and the effect from divestments was -7 percent.

Profile Systems was negatively affected by cold weather during the first two months of the quarter, which dampened construction activity, particularly in the core markets of Denmark, Norway and Sweden. The weather-related conditions resulted in reduced volumes and project delays during the period.

Overall, the quarter was characterised by low construction activity and weak volumes in several markets. Towards the end of the quarter, activity levels increased, contributing to positive organic growth in March.

Profit

Operating profit for Profile Systems amounted to SEK -26 m

(7). Earnings were significantly impacted by continued low

volumes, particularly in Scandinavia, where construction activity was weak at the beginning of the quarter. The combination of weather-related delays and lower sales volumes had a negative impact on capacity utilisation and, consequently, operating profit during the period.

In a continued uncertain market environment, Lindab Group has prioritised maintaining gross margin levels. This is considered crucial to safeguarding long-term profitability, despite a short-term negative impact on volumes and earnings.

Operating profit was also impacted by weak profitability in the remaining profile operations in Romania. The divestment of the operations has been slightly delayed due to extended processing times with the relevant authority and is expected to be completed during the second quarter. Furthermore, operating profit was affected by the previously communicated relocation of sandwich panel production from Luleå to Piteå. Production and sales have not yet reached the same levels as prior to the relocation.

Cash flow

Cash flow from operating activities amounted to SEK 45 m

(160) in the first quarter. Cash flow before changes in working capital amounted to SEK 227 m (236), slightly lower than in the previous year.

The change in cash flow from operating activities compared with the previous year was mainly attributable to a more negative impact from changes in working capital of SEK 182 m (-76). This was primarily due to higher accounts receivable and an increase in inventories, which was partly offset by higher accounts payable. The outcome is in line with the Group's normal seasonal pattern, where the first quarter has historically been weak in terms of cash flow as a result of working capital build-up. The effect was further reinforced by lower sales during January and February, partly due to unusually cold winter weather.

The negative impact from working capital was partly offset by lower net payments related to interest and income taxes amounting to SEK -110 m (-152), which contributed positively to cash flow compared with the previous year.

Cash flow from investing activities, excluding acquisitions and divestments of subsidiaries, amounted to SEK -66 m (-83). No acquisitions or divestments with a cash flow impact were carried out during the period January-March 2026 (-24).

Cash flow from financing activities amounted to SEK 0 m (-48) and included repayments of lease liabilities, which were offset by increased borrowings and utilization of credit facilities during the period.

Adjusted free cash flow amounted to SEK -21 m (77) for the quarter, primarily explained by a lower operating profit and increased capital tied up during the period. Cash conversion amounted to -11 percent (34).

Q1 2026

Net debt and financing

Net debt amounted to SEK 4,410 m (4,366) as of 31 March, of which SEK 1,474 m (1,559) related to lease liabilities.

The equity/assets ratio was 50 percent (47), and the net debt/equity ratio was 0.6 (0.6). Net financial items for the quarter amounted to SEK -50 m (-43). Decreased market interest rates has resulted in lower interest rates in the quarter. Net financial items in the same period previous year was however affected by a positive currency rate effect related to contingent consideration from the acquisition of Airmaster.

The existing credit agreement of SEK 4,050 m and EUR 120 m with Nordea, DNB Bank, Svenska Handelsbanken and Danske Bank is valid until the second quarter of 2028. An extension option allows for a one-year prolongation of maturity. The agreement is subject to a covenant which is monitored quarterly. Lindab Group met the covenant requirements as of 31 March 2026.

In addition, the credit facility is linked to three sustainability targets, whereby the interest margin is adjusted based on the level of target achievement. The targets are as follows:

  • Safer working environment: Improvement of workplace safety through a reduction in LTIF (Lost Time Injury Frequency).

  • Reduced scope 1 and 2 emissions: A continuous reduction of the Group's direct and indirect greenhouse gas emissions attributable to its operations.

  • Reduced emissions from purchased steel (part of scope 3): A reduction of emissions related to purchased steel used in Lindab Group's products.

All sustainability targets were met as of the end of 2025, resulting in a reduction of the interest margin during the first quarter of 2026.

Business combinations

No acquisitions or divestments were completed during the first quarter. In December 2025, Lindab Group entered into an agreement to divest its operations in Romania. The transaction was expected to be completed during the first quarter of 2026 but has been delayed due to extended processing times with the relevant authority. The divestment is now expected to be completed before the end of the second quarter of 2026.

For further information on acquisitions and divestments, see Note 3.

Q1 2026

Lindab Group's sustainability work 2025

In 2025, Lindab Group continued to advance its sustainability efforts while supporting customers and society in line with the direction "For a better climate".

Lower CO2e emissions - own activities

Lindab Group's CO2e emissions have decreased by 52 percent, from 20,856 tonnes in 2022 to 9,918 tonnes in 20251). The positive trend is partly a result of the commissioning of solar panel installations at Lindab Group's operations in the Czech Republic, Italy and Ireland in 2025. Several Group companies have also switched to renewable electricity, which has a significant impact on scope 22) emissions.

Work on assessing suppliers has moved forward, especially in high-risk countries3). Despite this, the target of 100 percent of suppliers being evaluated and approved has not yet been achieved. This is mainly due to newly acquired companies needing more time to implement Group-wide processes.

  1. Scope 1: Direct emissions that occur within the company's own operations. Scope 2: Indirect emissions from the generation of purchased electricity, steam, heating, and cooling consumed by the company. Scope 3: Emissions from the value chain from purchased goods and services, upstream transportation, waste generated in operations and the use of sold products.

  2. Market-based method.

  3. Suppliers in low and medium risk countries with an annual spend of at least 100 KEUR and in high risk countries with an annual spend of at least 25 EURK, are included. Suppliers added through acquisitions will be certified during their first year as part of the Group.

Other

Parent Company

Lindab International AB (publ), corporate identification number 556606-5446, is a registered limited liability company with its domicile in Båstad, Sweden. The Lindab share is listed on Nasdaq Stockholm, Large Cap.

Net sales for the quarter amounted to SEK 2 m (2). Profit for the quarter amounted to SEK -1 m (-3).

Significant risks and uncertainties

There have been no significant changes in relation to what was stated by Lindab Group in its Annual Report for 2025 under Risks and Risk Management (pages 58-59).

Employees

The number of employees, calculated as full-time equivalent employees, was 4,979 (5,046) at the end of the quarter. Adjusted for acquisitions and divestments, the net decrease was 21 employees compared to the same quarter previous year.

Seasonal variations

Lindab Group's business is affected by seasonal variations in the construction industry, and the highest proportion of net sales is normally seen during the second half of the year. The largest seasonal variations can be found in the segment Profile Systems. Ventilation products are mainly installed indoors which is why the Ventilation Systems segment is less dependent on season or weather conditions.

The Board of Directors has decided that the Annual General Meeting will be held on May 12, 2026. Notice to the meeting has been given via press release and has been published at lindabgroup.com.

Dividend

Lindab´s Board of Directors proposes that the Annual General Meeting on May 12, 2026, resolves a dividend of SEK 5.60 per share. This is in accordance with the dividend policy of minimum 40 percent of Lindab's profit, considering the Groups' financial position, acquisition opportunities and long-term financial needs. The proposed dividend corresponds to

SEK 431 m. The total value of actually paid dividend might be different if the number of treasury shares is amended before resolved record dates.

Dividend is proposed to be distributed on two occasions with SEK 2.80 per share and occasion. As record dates for right to dividend, May 15, 2026, and November 3, 2026, are proposed. Dividend is expected to be distributed to shareholders on May 20, 2026, and November 6, 2026.

Notes

Note 1

Accounting policies

The consolidated financial statements for the interim report have, in accordance with the annual financial statements for 2025, been prepared in compliance with International Financial Reporting Standards (IFRS® Accounting Standards) and interpretations issued by the IFRS® Interpretations Committee (IFRIC Interpretations), as adopted by the European Union, and the Swedish Annual Accounts Act.

The interim report has been prepared in accordance with IAS 34 Interim Financial Reporting. The Group applies the same accounting policies and calculation methods as described in the Annual Report for 2025. The interim report for Lindab Group should be read in conjunction with the Group's Annual Report for 2025, as it provides additional information and disclosures.

None of the new or amended standards, interpretations or improvements adopted by the EU have had any material impact on the Group. Standards issued but not yet effective have not been applied early.

Disclosures in accordance with IAS 34 paragraph 16A Interim Financial Reporting are provided both in the notes and elsewhere in the interim

report.

The Parent Company

The financial statements of the Parent Company have been prepared in accordance with the Swedish Annual Accounts Act and RFR 2, Accounting for Legal Entities, issued by the Swedish Council for Sustainability and Financial Reporting, and in accordance with the same accounting policies as applied in the Annual Report for 2025.

Note 2

Effects of changes in accounting estimates and judgements

Significant estimates and judgements are disclosed in Note 4 of the Annual Report for 2025. No changes have been made to the significant estimates and judgements described in the Annual Report for 2025 that are considered to have had any material impact on the Group's financial position or results during the current interim period.

Note 3

Business combinations

Adjustments to contingent consideration from the acquisition date until the settlement date are recognized in the income statement. Financial effects arising from revised assessments are reported as other operating income or other operating expenses, respectively. Discount effects related to the present value calculation of contingent consideration are recognized in the Group's net financial items, together with any related foreign exchange effects.

Reported operating profit was not materially impacted during the quarter by changes in assessments of outstanding contingent considerations. The Group's net financial items for the period January-March were charged with a minor discount expense attributable to contingent considerations measured at fair value in accordance with level 3 of the fair value hierarchy. No unrealised foreign exchange effects arose during the period.

The contingent considerations are paid in full or in part depending on whether future expectations regarding identified profit levels are met over a two or three year period. The possible undiscounted amount for all outstanding future contingent considerations ranges between SEK 0-668 m. As of 31 March 2026, 11 percent of the maximum outcome was expected to occur, impacted by the fact that the Airmaster contingent consideration of SEK 580 m is not expected to be paid.

Note 4

Assets held for sales

On 11 December 2024, Lindab Group announced the decision to restructure its operations in Eastern Europe to fully focus on the ventilation business in the region. The decision was based on a strategic review of the Profile Systems business area in the affected markets. As a result of the restructuring, the profile operations in the Czech Republic, Poland and Estonia were discontinued during the first quarter of 2025. The operations in Slovakia and the profile operations in Hungary were divested in Q2 and Q4 2025, respectively.

In December 2025, Lindab Group entered into an agreement to divest the operations in Romania. Completion, which was initially expected to take place during the first quarter of 2026, has been delayed due to extended processing times with the relevant authority. The divestment is now expected to be completed during the second quarter of this year. Considering the above decision, and taking into account the organisational and financial structure of each unit, all criteria under IFRS 5 Non

current Assets Held for Sale and Discontinued Operations continue to be met for the operations in Romania. The operations have therefore been classified as assets held for sale since the end of the fourth quarter of 2024. Below is a summary of the assets that, at the reporting date, are recognised as held for sale in accordance with the aforementioned standard.

The decision to divest and discontinue all profile operations in Eastern Europe, as communicated in the fourth quarter of 2024, affected approximately 250 employees within Lindab Group. Net sales from the remaining operations covered by the decision amounted to SEK 25 m (99) during the first quarter of 2026, and adjusted operating profit amounted to SEK -6 m (-1).

.

Note 5

Operating segments

The Group's segments consist of Ventilation Systems and Profile Systems. The basis for segmental reporting is the various customer offers provided by each business area. The customer offers within each segment were as follows:

  • Ventilation Systems offers air duct systems with accessories and indoor climate solutions for ventilation of heating and cooling to installers and other customers in the ventilation industry.

  • Profile Systems offers the construction industry products and systems in sheet metal for rainwater systems, cladding for ceilings and walls as well as steel profiles for wall, ceiling and beam constructions.

Both Ventilation Systems' and Profile Systems' operations are managed based on geographically divided sales organisations, which are supported by a number of product and system areas with joint production and purchasing functions for each business area. What is reported under Other includes the Parent Company and other common functions.

Information on income from external customers and adjusted operating profit per operating segment is presented in the tables on page 11. See also pages 5-6 for further segment information.

Internal prices between the Group's segments are set based on the principle of arm's length, that is, between parties that are independent of each other, well-informed and have an interest in the transaction being carried out. Assets and investments are reported where the asset exists.

Note 6

Investments

Investments in intangible assets and tangible fixed assets during the quarter amounted to SEK 70 m (86), of which SEK 27 m (29) was related to investments in intangible assets.

Note 7

Depreciation/amortisation and impairment

Depreciation and amortisation for the quarter amounted to SEK 167 m (174), of which SEK 54 m (57) was related to tangible fixed assets, SEK 15 m (18) was related to intangible assets and SEK 98 m (99) to right of use assets. No Impairment losses were reported in the quarter (SEK 0 m).

Description of fair value

Derivates

Derivatives relate to forward exchange contracts which are valued at fair value by discounting the difference between the contracted forward

rate and the forward rate that can be subscribed for on the balance sheet date for the remaining contract term. Derivative assets and derivative liabilities that are recognised can all be found at level 2 of the fair value hierarchy, based on the definition of IFRS 13 Fair Value Measurement.

Liabilities to credit institutions

The fair value of interest-bearing liabilities to credit institutions is disclosed for information purposes. The fair value is calculated by discounting the future cash flows of principal and interest using the current market interest rate.

Acquisition-related contingent consideration

Acquisition-related contingent consideration refers to financial liabilities that arose in connection with business combinations and are measured at fair value. The fair value has been determined by discounting of cash flows and is classified as level 3 in the fair value hierarchy as defined

in IFRS 13 Fair Value Measurement. Recognised fair value corresponds to the present value obtained by discounting a probability-weighted average of possible future cash flows, which are assessed to be settled according to existing acquisition agreements, and with a discount factor that is based on a risk-adjusted discount rate.

The fair value of acquisition-related contingent consideration is primarily sensitive to assumptions about discount rates and future cash flows. Reasonably possible changes in these assumptions would only result in marginal changes in the fair value. Such changes are not considered to have any material impact on the Group's financial position or results.

Other

During the period, there has not been any transfers between the levels of the fair value hierarchy. There were no significant interrelationships between non-observable data that significantly affect fair values.

For other financial assets and liabilities, the carrying amount is deemed to be a reasonable approximation of fair value. The Group holdings of unlisted shares, and where the fair value cannot be estimated reliably are recognised at acquisition cost. The recognised carrying amount for these holdings are SEK 4 m (4).

Note 9

Tax

Profit before tax for the quarter amounted to SEK 138 m (185) and tax cost was SEK 29 m (40). The effective tax rate amounted to 21 percent (22), while the average tax rate was 21 percent (21). The actual difference between the effective tax rate in the quarter and the corresponding

tax rate in the same period previous year was marginal. In the period, Lindab Group has taken into account the rules on global minimum level taxation according to Pillar Two. The impact of the rules on the effective tax rate was limited.

Note 10

Related party transactions

Lindab Group's related parties and the extent of transactions with related parties are described in Note 33 in the 2025 Annual Report. During the period, there have been no other transactions between Lindab Group and related parties which have had a significant impact on the company's position and profit.

The interim report for Lindab International AB (publ) has been submitted following approval by the Board of Directors.

Reconciliations, key performance indicators not defined according to IFRS

The company presents certain financial measures in the interim report which are not defined according to IFRS. The company considers these measures to provide valuable supplementary information for investors and the company's management as they enable the assessment of relevant trends.

Lindab Group's definitions of these measures may differ from other companies' definitions of the same terms. These financial measures should therefore be seen as a supplement

rather than as a replacement for measures defined according to IFRS. Definitions of measures which are not defined according to IFRS and which are not mentioned elsewhere in the interim report are presented below. Reconciliation of these measures is shown in the tables below. As the amounts in the tables below have been rounded off to SEK m, the calculations do not always add up due to round-off.

No one off items and restructuring costs were reported during the quarter or in the corresponding period of the previous year. For the period January-December 2025, one off items and restructuring costs amounted to SEK 70 m, of which SEK 291 m related to a non-recurring income attributable to a reduction of the contingent consideration related to Airmaster. The remaining amount related to impairments and disposals of intangible and tangible fixed assets amounting to SEK -115 m, as well as restructuring measures to optimise branch networks in the Group's larger European markets. During the first quarter of 2026, a non-material portion of the restructuring provision has been utilised.
