Comments from the President and CEO, Heikki Vuorenmaa Our growth in revenue, profitability and order book continued during the third quarter of 2026. Our Group revenue increased by 14% during the quarter, as both of our contracting segments delivered strong growth, and the Residential CEE segment maintained its positive momentum. This broad-based growth supported the improvement of YIT's profitability, resulting in a 26% increase in Group adjusted operating profit. Our order book for the contracting segments strengthened significantly, with new orders totaling more than EUR 900 million in the quarter. While data center construction is our fastest-growing business, growth in the Infrastructure and Building Construction segments came from projects from multiple customer groups. Our operative efficiency continued to improve, supporting a positive profitability trend in the contracting segments, and the growing share of data center construction in our portfolio is expected to provide further support for profitability improvement from 2027 onwards. We hosted a Capital Markets Update during the quarter to clarify how we are positioned to capitalize on the growth opportunities in the Finnish data center market. We have demonstrated our ability to deliver some of Finland's most advanced projects, and we continue to expand our capacity as the demand grows. Proven delivery capabilities, strong references and integrated execution enable YIT to capture Finland’s data center growth and convert it into long-term profitable growth. Our growth profile is expected to be dominated by data center construction in the coming years. We see a credible path to generating approximately EUR 1 billion in revenue from our data center business in 2029, provided that power availability develops as expected, customer investment activity continues, and projects progress under normal delivery conditions. Driven by the strong growth in the data center market, we increased our growth targets set for the strategy period. Group financial target for annual revenue growth to be reached by the end of 2029 was doubled to 10%. In conjunction, we increased the annual growth targets for the Infrastructure and Building Construction segments to 15% and 6% respectively. The Residential CEE segment continued to deliver strong profitability, at 14.3% year-to-date. New residential project starts were moderate during the third quarter, with most project launches in 2026 expected to take place in the final quarter of the year. In this favorable market, the segment’s growth potential is more dependent on our ability to allocate capital to the segment over medium-term. In the Residential Finland segment, we have developed and launched three new customer-centric residential concepts during the year: Formia, Olo and Fiksu. All three concepts are now on the market, and the first projects developed under these concepts have received a positive response from our customers. The cost savings measures implemented as part of the operating model change are already partially reflected in the segment's performance, although low volumes continue to weigh on profitability. We remain committed to restoring the business to profitability, irrespective of market conditions. Several indicators point to an improving outlook for the Finnish economy. Growth is broad-based, and employment is expected to strengthen. As noted by the Confederation of Finnish Construction Industries RT in its autumn economic outlook, the economic recovery, combined with the decline in residential supply, is creating conditions for a rebound in residential construction in 2027. The market remains consumer-driven, and a broad-based recovery in the residential market remains still some way off. Elevated interest rates remain a key concern for the real estate sector. This was reflected in the valuation of our partly owned Tripla shopping center, as the applied yield requirement increased. Higher interest rates may also continue to delay the recovery of the residential market, particularly in the investor segment, despite the encouraging signals from other economic indicators related to the consumer market. The megatrends underpinning our strategy continue to strengthen, reinforcing our positive long-term outlook. Beyond data centers, we see further growth opportunities across our businesses arising from urbanization, the energy transition, and increased investments in infrastructure and defense. YIT has the capabilities, market position and customer relationships to capture these opportunities and translate them into long-term growth. Our systematic and determined focus on safety has delivered a significant improvement in work safety performance. Achieving meaningful progress requires strong engagement from all parties. Our goal is clear: There should not be any accidents on YIT's worksites. To measure the development, we set a reduction target to halve the cLTIF metric during the strategy period. To achieve this, we need to sustain a collective focus on safety across our supply chain. Heikki Vuorenmaa President and CEO YIT Corporation Interim Report 1–9/2026 5 (38)

Guidance and outlook for 2026 YIT narrows the range for the adjusted operating profit guidance for year 2026 as a result of stable financial performance of the businesses during the first nine months of the year. Revised guidance for 2026 YIT expects its Group adjusted operating profit* for continuing operations to be EUR 80-90 million in 2026. Previous guidance for 2026, issued on February 6, 2026 YIT expects its Group adjusted operating profit* for continuing operations to be EUR 70-100 million in 2026. Outlook for 2026 The residential market in the Baltic countries and Central Eastern Europe is expected to continue favorable, contributing positively to Residential CEE segment's capability to generate profit. In Finland, the primary apartment market sales volumes are not expected to increase in 2026. In Building Construction, the operational performance is expected to improve. In Infrastructure, the operational performance is expected to remain stable. Changes in the macroeconomic or global political environment may impact the residential market demand and the fair value of investments. The escalation of geopolitical risks reflected in general uncertainty and demand could have a negative impact on the company’s financial performance. *Adjusted operating profit is based on segment reporting.

Market environment Residential market, Finland The primary apartment market sales volumes are not expected to increase in 2026. An economic recovery, combined with the decline in residential supply, is creating conditions for a rebound in residential construction in 2027. The market remains consumer-driven, and a broad-based recovery in the residential market remains still some way off. In the investor market, transaction volumes have shown early signs of picking up, but the overall level of activity remains low and the timing of a recovery remains uncertain. Higher interest rates may continue to delay the recovery of the residential market, particularly in the investor market, despite the encouraging signals from other economic indicators related to the consumer market. Residential market, CEE Residential markets across the CEE and Baltic regions remained broadly resilient during the third quarter, supported by strong long-term residential fundamentals and structural residential undersupply. While geopolitical tensions in the Middle East have increased inflationary risks and contributed to a more cautious interest rate environment, residential demand has remained stable across YIT's operating markets. Overall, residential market conditions continued to normalize. Poland and Czechia remain key markets in the region. In the Baltics, positive sentiment continued in Latvia, while Estonia showed early signs of improvement. Building construction market Building construction starts in Finland have started to increase, as a result of the increased volumes in the data center market. Building permits continued to increase, with data centers being the most significant driver. In other private sector, limited availability of financing and global uncertainty continue to delay investment decisions and, consequently, project starts. Public sector investments remain stable, and new delivery models such as lease-based models have become more common in public procurement. Due to the overall low volume, the competitive environment in the market remains intense. Transaction volumes in the real estate market are also being weighed down by constrained financing availability, high yield requirements, and a shift of investments towards other asset classes. In the Baltic and Central Eastern European countries, overall demand and market activity remained stable, especially supported by private sector demand for new industrial premises and defense sector investments in certain countries. In the Baltic countries, new project starts are facing challenges due to yield requirements. Infrastructure market The overall outlook in the Finnish infrastructure market remains positive. Private sector outlook remains strong driven by exceptionally high level of investments focusing on data centers. In addition, investments in renewable energy supply and energy storage are expected to increase, and there are numerous clean transition projects in the planning phase. Public sector demand for traffic infrastructure construction is expected to remain stable with robust pipeline of projects expected to proceed to construction phase. Increasing investments in security of supply and defense are expected to support the market outlook going forward.

Strategy implementation progress Strategy implementation progress is monitored in detail quarterly for every segment. The data center market in Finland is experiencing strong growth, as Finland is emerging as one of the most attractive locations for data center investments in Europe. YIT has systematically invested in its capabilities in this growing sector, built extensive expertise and references in delivering demanding data center projects, and established a position as Finland’s leading data center builder. The announced and potential data center pipeline represents a significant growth opportunity for YIT during the 2025–2029 strategy period. As a result, YIT announced on September 24, 2026, that it increases its Group financial target for revenue growth to be reached by the end of 2029 to at least 10%, with the compound annual growth rate (CAGR) based on year 2024. Previously, the corresponding target was a CAGR of at least 5%. The other Group financial targets of adjusted operating profit margin of at least 7% and return on capital employed of at least 15% by the end of 2029 remain unchanged. In conjunction, YIT also increased the segment specific revenue growth targets for the Building Construction and Infrastructure segments for the strategy period. The new target for the Building Construction segment is to achieve annual growth of at least 6% and for the Infrastructure segment to achieve annual growth of at least 15% by 2029, with the compound annual growth rate (CAGR) based on year 2024. Previously, the Building Construction segment’s corresponding target was a CAGR of at least 4% and Infrastructure segment’s target a CAGR of at least 10%. Safety development YIT's strategy for 2025-2029 sets a target for a combined lost time injury frequency (cLTIF) of below 5 in all operations. YIT’s combined lost time injury frequency was 7.8 (9.6) in the third quarter of 2026. YIT has worked systematically to increase the number of observations, and to promote low-threshold intervention, feedback and employee well-being enhancing the strategic importance of work safety.

Basis of preparation and accounting policies of the Interim Report Basis of preparation This Interim Report has been prepared in accordance with IFRS Accounting Standards recognition and measurement principles, but not all the requirements of IAS 34 Interim Financial Reporting standard have been applied. This Interim Report should be read together with YIT’s consolidated Financial Statements 2025. The figures presented in the Interim Report are unaudited. In the Interim Report, the figures are presented in million euros doing the rounding on each line, which may cause some rounding inaccuracies in columns and total sums. Accounting policies The same IFRS Accounting Standards recognition and measurement principles have been applied in the preparation of this Interim Report as in YIT’s consolidated Financial Statements 2025, except for the amendments to the IFRS Accounting Standards effective as of January 1, 2026 and the change in segment reporting described in the following paragraphs. The IFRS Accounting Standard amendments had no impact on the consolidated financial statements. Percentage of completion revenue recognition method in segment reporting Starting from the first quarter of 2026, YIT reports self-developed projects using the new revenue recognition method in segment reporting. Going forward, revenue from sales of self-developed projects will be reported using the percentage of completion method, in contrast to the previously used method where revenue was reported upon project completion, when control is transferred to the customer. Figures reported to the chief operating decision maker (CODM) are based on segment reporting. YIT’s segment reporting aligns with IFRS accounting principles, except for revenue recognition in self-developed projects, where an over time revenue recognition method—also called the percentage of completion (POC) method—is applied. The difference between IFRS accounting principle and segment reporting primarily affects the segments involved in self-developed real estate construction. Under IFRS 15 Revenue from Contracts with Customers, revenue from self-developed projects is recognized at a point in time, typically when the control of the asset is transferred to the customer, which usually occurs upon completion. For segment reporting, YIT applies over time revenue recognition for self-developed projects. This method recognizes revenue over time based on the project's progress and sales performance. Recognition is determined by two key factors: • Completion rate, reflecting the progress of the construction project • Sales rate, reflecting the proportion of projects sales rate. Completion rate is measured using the same methodology applied to customer contracts where revenue is recognized over time under IFRS accounting principles, and also the same management judgment and estimates consistently apply for segment reporting. These judgments involve forecasted revenues and costs, determining performance obligations and estimating the transaction price. Percentage of completion method is not applied in segment reporting for self-developed projects in joint ventures or associated c o m p a n i e s ; i n s t e a d , r e v e n u e i n t h e s e e n t i t i e s i s r e c o g n i z e d i n a c c o r d a n c e w i t h I F R S 1 5 , i . e . , a t a p o i n t i n t i m e w h e n c o n t r o l i s transferred. Income taxes are adjusted based on the segment reporting for the purpose of calculating result for the period. Result for the period and earnings per share are included in segment reporting only at the group level. Operative capital employed is reported as part of segment reporting reflecting items aligned with the company’s strategy and revenue recognition method applied in segment reporting. The differences between IFRS and segment reporting are disclosed in the notes below. Reconciliations are provided to align segment reporting and IFRS figures. Segment reporting figures are presented in tables with a gray background. Significant management judgments In preparing this Interim Report, significant judgments made by management in applying the accounting policies and the key sources of estimation uncertainty were the same as those described in the consolidated Financial Statements for the year ended 31 December 2025.

Investment commitments are related to joint ventures, associated companies and equity investments. Purchase commitments are mainly pre-contracts for plot acquisitions, the realization of which typically depends on the implementation of zoning. The value of the plot purchase commitments is an estimate which is subject to zoning, amount of building rights and changes in cost indexes. In addition, the amount presented in the notes is based on the estimated acquisition value of the plot, despite conditionalities or possible termination clauses in the contract. YIT has entered into option agreements related to plots, under which YIT obtains a contractual right, but not an obligation, to acquire the land once the conditions to exercise the option are met. Upon signing, YIT does not assume a present obligation to acquire the land or to continue the contract beyond the current option period. However, the agreements may involve potential future outflows, such as the payment of option fees, and a risk that the contract could later become onerous if the option is not exercised and YIT is unable to transfer or otherwise exit the arrangement. Accordingly, the arrangements are disclosed as contingent liabilities. YIT Corporation Interim Report 1–9/2026 33 (38)

IFRS Accounting Standards, interpretations and amendments not yet effective IFRS 18 Presentation and Disclosure in Financial Statements IFRS 18 Presentation and Disclosure in Financial Statements introduces new requirements for the presentation of financial performance and related disclosures. The standard replaces IAS 1 Presentation of Financial Statements and is effective for annual reporting periods beginning on or after 1 January 2027. IFRS 18 will be applied retrospectively, and YIT is preparing for the adoption of the standard and the related restatement of comparative financial information. IFRS 18 introduces a defined structure for the statement of profit or loss, including operating, investing and financing categories and the new required subtotals operating profit and profit before financing and income taxes. The standard also introduces disclosure requirements for management-defined performance measures and enhanced principles for the aggregation and disaggregation of information. The consequential amendments to IAS 7 will also result in changes to the presentation of the statement of cash flows. Based on YIT’s implementation work to date, the main changes in the statement of profit or loss relate to the classification of certain items. The share of results of associated companies and joint ventures, fair value changes in financial assets and certain income and expenses arising from financial assets will be presented in the investing category. Income and expenses arising from financing liabilities, including the effects of discounting provisions, will be presented in the financing category. Foreign exchange differences will be classified in the same category as the income or expense arising from the underlying item. The changes will affect operating profit and certain other subtotals but not YIT’s revenue, result for the period or equity. The consequential amendments to IAS 7 will also change the presentation of YIT’s statement of cash flows. As YIT presents cash flows from operating activities using the indirect method, operating profit will be used as the starting point. Interest paid will be classified as a financing cash flow, while interest and dividends received will be classified as investing cash flows. These changes will affect the allocation of cash flows between operating, investing and financing activities but will not affect the total net change in cash and cash equivalents. The Group has assessed the performance measures used in its public financial communications against the IFRS 18 requirements concerning management-defined performance measures. The assessment will be finalized before the publication of the Group’s first interim report for 2027, in which IFRS 18 will be applied for the first time.

Definitions of financial key performance indicators Key figure Definition Reason for use Operating profit Result for the period before taxes and finance expenses and finance income equalling the subtotal presented in the consolidated income statement. Operating profit represents the result generated by operating activities excluding finance and tax-related items. Adjusted operating profit Operating profit excluding adjusting items. Adjusted operating profit is presented in addition to operating profit to reflect the underlying core business performance and to enhance comparability from period to period. Management believes that this alternative performance measure provides meaningful supplemental information by excluding items not part of YIT’s core business operations thus improving comparability from period to period. Adjusting items Adjusting items are material items outside ordinary course of business such as write-down of inventories, impairment of goodwill, fair value changes related to redemption liability of non-controlling interests, integration costs and expenses related to merger, transaction costs and expenses related to merger, costs, expenses, compensations and reimbursements related to claims and litigations, costs, expenses, profits, gains and losses related to non-strategic items, write downs related to non-core businesses, operating profit from businesses to be closed down, gains or losses arising from the divestments of a business or part of a business, items related to restructuring, efficiency and adaptation measures and other non-recurring costs arising from agreements with the Group management team, impacts of the fair value adjustments from purchase price allocation, such as fair value adjustments on acquired inventory, depreciation of fair value adjustments on acquired property, plant and equipment, and amortization of fair value adjustments on acquired intangible assets relating to business combination accounting under the provisions of IFRS 3, referred to as purchase price allocation (“PPA”).
