Wärtsilä presents certain alternative performance measures in accordance with the guidance issued by the European Securities and Markets Authority (ESMA). The definitions of these alternative performance measures are presented in the Calculations of financial ratios section. Wärtsilä's outlook Marine Wärtsilä expects the demand environment for the next 12 months (Q3/2026-Q2/2027) to be similar to that of the comparison period. Energy Wärtsilä expects the demand environment for the next 12 months (Q3/2026-Q2/2027) to be similar to that of the comparison period. Following two consecutive record order intake quarters in Energy and a record-high order intake in Marine in the second quarter, the outlook reflects a continued strong demand environment, especially in Energy. The strong demand environment is clearly underscored by Wärtsilä's decision in the second quarter to further expand capacity. ‌Håkan Agnevall, President & CEO: Record-high orders drive a strong quarter The second quarter of 2026 was strong for Wärtsilä. We achieved an all-time high order intake, while further improving profitability. Elevated geopolitical tensions continued to influence the operating environment. In particular, the conflict in the Middle East increased volatility in the energy and commodity markets, adding complexity to market conditions and contributing to a more uncertain global economic outlook. In the energy market, electricity demand continued to grow, supported by electrification, rising cooling needs, and the rapid build-out of data centres. The recent heat wave in Europe, together with rising temperatures globally, has highlighted the growing pressure on power systems. This reinforces the need for reliable and flexible power generating capacity to ensure a robust supply during peak demand periods. Wärtsilä's flexible engine technology is well positioned to meet these requirements, offering fast-ramping and highly efficient capacity that complements renewable generation and supports grid stability. The interest from the data centre segment remained strong, with a dynamic pipeline of opportunities. The market is increasingly driven by the need for efficient, reliable, and scalable power solutions to support critical operations. A recent BloombergNEF analysis highlights the competitiveness of reciprocating engines in this market, identifying engines as the most cost-competitive technology option for AI data centres. In addition to attractive lifecycle economics, engines offer a low heat rate, low site-level emissions, and negligible water consumption. These qualities are highly relevant in a fast-developing market where long-term performance and resource use are becoming increasingly important. The resulting growth in the installed base also supports significant lifecycle service potential in 2030 and beyond. The marine market remained strong despite the continued uncertainty. Geopolitical disruptions, particularly in the Middle East and around the Strait of Hormuz, have led to longer voyage distances, trade rerouting, and strategic stockpiling of commodities, which together generally support vessel utilisation and freight rates. Decarbonisation also remains an integral part of the operating environment. Regulations for international shipping, including China's new carbon-intensity reduction target, are supporting the industry's focus on more efficient and future-ready vessels - areas where Wärtsilä is well positioned through its newbuild solutions and lifecycle services offering. In the second quarter of 2026, Wärtsilä's order intake increased organically by 43% to a new all-time high, supported by record quarterly orders in both Energy and Marine. In Energy, order intake surpassed the previous all-time high set in the first quarter of 2026 by more than 70%, largely as a result of 1.2 GW of firm data centre-related orders across two projects and more than 0.5 GW in balancing orders. Robust demand in Energy has contributed to more than doubling the Energy order book since the start of 2025. Over the same period, the gross margin of the Energy equipment order book has improved by more than 500 basis points. During the quarter, we announced a further expansion of production capacity at our Sustainable Technology Hub (STH), strengthening our ability to meet growing global demand. Once fully commissioned in the first quarter of 2029, the expansion will increase output to approximately 2.2 times the 2025 operational level. Organic service order intake remained stable. Marine and Energy combined service order book increased by 11%, ending up at an all-time high. The rolling 12-month service book-to-bill ratio remains above 1, reflecting our continued progress in moving up the service value ladder. Net sales increased organically by 5%, driven by growth in equipment deliveries. Equipment delivery times continued to increase, impacting the timing of revenue recognition. Consequently, the existing order book will generate sales that are distributed further into the future. The comparable operating result increased by 7% to EUR 218 million, representing 14.0% of net sales. Cash flow from operating activities amounted to EUR 497 million, following a good level of received customer payments. We expect to sustain a negative working capital position over the coming years, and will continue our active efforts to maintain working capital well below our long-term historical average. During the quarter, we continued to actively streamline our portfolio. On 1 June 2026, we completed the divestment of Water & Waste to Solix Group AB and Gas Solutions to Mutares SE & Co. KGaA. With these transactions, all businesses previously reported under Portfolio Business have now been divested, marking an important milestone for Wärtsilä. On 15 June 2026, Wärtsilä agreed to establish a 50/50 joint venture with German company RCT Solutions GmbH for its global Energy Storage business. Closing is expected in the third quarter of 2026. The transaction offers the Energy Storage business an opportunity to strengthen its long-term competitiveness. We expect the demand environment over the next 12 months to remain at a similar level in both Energy and Marine as in the past 12 months. Following two consecutive record order intake quarters in Energy and a record-high order intake in Marine in the second quarter, the outlook reflects a continued strong demand environment, especially in Energy. The strong demand environment is clearly underscored by our decision in the second quarter to further expand capacity. With our global team of dedicated professionals, we are executing our strategy with discipline and consistency. Following the streamlining of our business portfolio, we are now a more focused and profitable company. We are well placed to further build on our strong market position and continue to capture opportunities for profitable organic growth. ‌Orders, net sales and profitability MEUR 4-6/2026 4-6/2025 Change 1-6/2026 1-6/2025 Change 2025 Order intake 2,849 2,140 33% 4,934 4,012 23% 7,647 Order book, end of period 8,976 7,963 13% 7,530 Net sales 1,559 1,594 -2% 3,004 3,027 -1% 6,219 Comparable operating result 218 203 7% 411 379 8% 805 % of net sales 14.0 12.7 13.7 12.5 12.9 Operating result 209 183 14% 399 354 13% 810 % of net sales 13.4 11.5 13.3 11.7 13.0 Order intake bridge MEUR 4-6/2026 1-6/2026 2025 2,140 4,012 Organic 43% 36% Acquisitions and divestments -7% -9% FX impact -2% -3% 2026 2,849 4,934 Development in April-June Order intake increased by 33%, driven by higher equipment orders.

This marks a clear set-back compared to earlier projections, with forecasts now revised down across most economies, despite the resilient AI-supported growth. The shift in outlook is driven primarily by the Middle East conflict, which has disrupted energy markets and global supply chains through sharp increases in oil, gas and fertiliser prices, renewed inflation, generally weaker confidence, and a negative impact on trade prospects. These effects are amplified by tighter monetary conditions and heightened geopolitical uncertainty, leaving the outlook highly fragile and dependent on the normalisation of energy supplies. Marine market Newbuild investment activity remained strong The marine market has remained strong despite the weaker near-term economic outlook and continued uncertainty. Geopolitical disruptions, particularly in the Middle East and around the Strait of Hormuz, have contributed to longer voyage distances, trade rerouting, and strategic stockpiling of commodities. This has generally supported tonne-mile demand, vessel utilisation, and freight rates. Overall, the shift from efficiency maximisation to trade and supply-chain resilience is supporting shipping earnings and asset values. Decarbonisation is an integral part of the operating environment, with regulations for international shipping, including China's new carbon-intensity reduction target, driving continued emissions-reduction efforts through different means, including fleet renewal, retrofitting of energy-saving devices, and sailing at slower speeds. Newbuild investment activity has been very strong in 2026 due to the positive market sentiment, a healthy earnings environment, and the continued drive for fleet renewal. Ordering has continued to be notably strong in crude tankers, while activity has remained healthy also for containerships, cruise vessels and LNG carriers. In total, 1,483 newbuild contracts were reported in H1/2026, compared to 647 contracts reported in H1/2025, excluding late reporting of contracts. A total of 245 orders for new, alternative fuel capable ships were reported, accounting for 17% (28) of all contracted vessels and 24% (55) of the capacity of contracted vessels. A period of continued strong newbuild activity has driven shipyard order books and lead times to their highest level since 2009, with the ships on order representing 20% of the current fleet capacity. Meanwhile, increases in shipyard capacity and ship delivery volumes have kept the average newbuild ship prices largely unchanged, declining only by 1% year-over-year. However, there is a clear divergence in order books and newbuild pricing between ship segments. . Market sentiment for Wärtsilä's key customer segments remains supportive In the cruise segment, market sentiment continues to be positive. Cruise lines reports of solid demand for cruises, coupled with strong execution, more than offset any negative implications stemming from the Middle East conflict. Cruise operators have established firm plans for new ship capacity into the late 2030s in line with their longterm expansion objectives, as slots at key shipyards are scarce. Moreover, cruise lines are prioritising energy efficiency to meet regulations and cut costs, which, along with continued fleet growth, is increasing service demand. In the ferry segment, market sentiment has become more neutral and mixed. The more challenging economic outlook, unsupportive newbuild economics, increases in regional emissions compliance costs, and regulatory uncertainty are all contributing to a moderation in sentiment and fleet renewal activity. The demand for service was supported by operator interest in maintaining and improving the efficiency of their ageing fleets . In the offshore segment, overall sentiment in the oil & gas market has strengthened due to a gradual pick up in vessel demand and the continued increase in day rates. The Middle East conflict has increased uncertainty for the outlook within the region, but has increased the focus on energy security globally, boosting the investment appetite and accelerating project timelines. Sentiment in the offshore wind sector was impacted by ongoing cost pressures and varied political support, which has affected investor confidence. This has resulted in project delays and a more limited interest in newbuilds. The demand for service across both offshore sub-segments was driven by high asset utilisation rates. In the LNG carrier segment, market sentiment was supported by growth in the long-haul trade of LNG. This helped to offset the decline in overall trade volumes caused by the conflict in the Middle East. Newbuild activity increased, with ordering being driven by the planned expansion in LNG export terminal capacity to support future trade volumes. The demand for service was supported by active utilisation and healthy charter rates, as demand for ships picked up, due both to seasonal demand and supply concerns following the Middle East conflict. In the containership segment, market sentiment was supported by the delayed rerouting to the Red Sea, which increased demand for vessels, and the earlier than usual peak-demand season triggered by importers seeking to front-load shipments in anticipation of higher US tariffs. Meanwhile, newbuild activity has remained elevated, with activity focused more on smaller and mid-sized ships as liner operators and tonnage providers pursue their fleet renewal plans. While overall service demand remained healthy as a result of high ship utilisation rates, it was negatively affected by the easing of earnings ahead of the Middle East conflict, and by continued uncertainty and complexity related to the near-term market outlook. Energy market Increased demand drives energy transition investments The global energy transition continues to move forward despite certain countries having reduced climate ambitions. Most research agencies, such as the IEA and BloombergNEF, have kept their global forecasts for wind and solar similar to previous levels, highlighting continued short- and long-term growth and annual capacity additions of hundreds of gigawatts. Favourable economics shield wind and solar from changes in policy, while at the same time, in most countries, policies continue to be supportive of renewables. Growth in clean power generation surpassed fossil fuels in 2025, with a record 814 GW of new solar and wind capacity installed in 2025, according to global energy think tank Ember. This represents an 11% year-on-year increase on an already-strong 2024, which emphasises the important role these technologies are playing in the global power system. Two key themes have continued to stand out in recent energy-related macroeconomic developments: load growth and increased uncertainties. Accelerated load growth from the electrification of industry, transport, cooling, as well as from data centre investments, has led to high demand for all power-producing assets, including gas-fuelled power. The recent heat wave in Europe, along with rising temperatures worldwide, is likely to increase demand for air conditioning, thus further driving load growth. The International Energy Agency (IEA) expects electricity demand to grow at least 2.5 times faster than overall energy demand between 2026 and 2030, with demand set to rise strongly across all sectors, leading to high market demand for power generation. This high market demand has led to longer delivery times, and industry participants have responded by expanding manufacturing capacity. The uncertain tariff and regulatory situation poses challenges to all actors due to its impact on global energy technology supply chains, while geopolitics have increased uncertainty, especially as a result of the war in the Middle East. The US and Israeli attacks on Iran, followed by Iranian retaliation and the near-closure of the Strait of Hormuz, severely disrupted global oil and gas flows in H1 2026, leading to an energy shock that increased oil prices and inflation forecasts. Despite peace talks, the situation in the Middle East remains unstable, as do oil and gas price forecasts. Many analysts expect the fuel supply shock to lead to a further push to electrify economies, which may increase the pace of the transition to renewables. In engine power plants, the market demand for equipment has been strong, with a growing need for balancing power, a resilient market for conventional baseload power, and rapid growth in demand for data centre power plants. In the balancing segment , the pace of the renewable energy transition continued to be an important demand driver. The total market for thermal balancing in 2025 had its second consecutive record year, and has continued at a strong level in Q1, according to data from McCoy Power Reports and from that gathered internally. The drivers for balancing demand are also expected to continue to develop favourably. For example, BloombergNEF expects wind and solar capacity additions to grow towards 2035, while supportive market reforms are developing, and old, inflexible coal and gas plants are being retired. The need for dispatchable generation in power systems with an increasing share of renewables was showcased in recent auctions in Brazil, which secured 19 GW in firm capacity and demonstrated a clear preference for gas-fired power plants. The baseload segment remains a consistent source of demand for thermal power. Reciprocating engines are important providers of baseload generation, particularly in remote locations and other locations where access to grid power is uncertain or time sensitive. Decentralised and island grids are a demand growth driver, with this segment often facing increasing electricity demand and grid reliability issues. There is a need to secure an affordable, sustainable, and reliable supply of energy, and engines offer a fuel-flexible solution to this problem. The data centre power landscape is undergoing a significant transformation. Rapid growth in high-tech industries and AI applications is driving unprecedented energy demand, making reliable on-site power essential. BloombergNEF recently recognised gas engines as a highly competitive technology to power data centres, finding them to be the most cost-competitive option, with the lowest levelised cost of energy (LCOE), beating both open-cycle and combined-cycle gas turbines. In addition to low lifecycle costs, high efficiency, low site-level emissions, and negligible water consumption are major advantages for reciprocating engines in a fast-paced developing market. The size of data centre projects has been trending upwards, as has the size of Wärtsilä's orders. Forecasts for global growth of data centre power continue to vary widely, but have generally increased in H1. The IEA sees electricity consumption from AI-focused data centres growing much faster than the overall data centre electricity consumption, expecting it to triple during the five-year period 2026-2030. ‌Sustainability Sustainability at the core of Wärtsilä's strategy With a broad range of technologies and specialised services, Wärtsilä is well positioned to support customers on their decarbonisation journey, as well as in preparing for new regulatory requirements. Wärtsilä's R&D efforts continue to focus on the development of advanced environmental technologies and solutions. Wärtsilä's aim is to be able to provide a product portfolio ready for zero-carbon fuels by 2030, and the company is well on track towards this target. In addition to promoting the transition to carbon neutrality for its customers, the company's goal is to become carbon neutral in its own operations by 2030. As regards reducing supply chain emissions, Wärtsilä targets a 25% reduction in GHG emissions from its direct suppliers by 2030. Enhancing safety, diversity, and wellbeing is also one of Wärtsilä's long-term sustainability focus themes. Safety is a high priority for Wärtsilä, and the company is committed to creating and maintaining a safe and healthy workplace for its employees and partners. Creating an inclusive culture that drives engagement and performance is one of the priorities of the People Strategy. The company is committed to supporting the UN Global Compact and its ten principles with respect to human rights, labour, the environment, and anti-corruption. Second quarter sustainability performance and highlights In June, Wärtsilä achieved a significant milestone by successfully testing the world's first large-scale engine operating with 100% hydrogen at its Bermeo laboratory in Spain. The engine supplied power to the Spanish national electricity grid, demonstrating that engine-based power generation can run entirely on hydrogen under real grid conditions. This development marks an important step beyond hydrogen-ready technologies and supports the transition towards fully renewable energy systems. Wärtsilä's four-year health and safety programme "Success through Safety", launched in 2023, focuses on four streams: employee safety, contractor safety, product safety, and occupational health. Implementation of the health and safety programme continues. In the second quarter, Wärtsilä held its 12th annual Safety & Wellbeing Week under the theme "Dare to Care", highlighting the importance of everyday actions in supporting each other's safety and wellbeing. The theme emphasised looking out for colleagues, checking in before and during work, and speaking up with curiosity and respect, while building a culture where it is safe to pause, question, and learn. This global initiative supports Wärtsilä's long-term commitment to a strong safety culture, which is fundamental to operational excellence and employee wellbeing. The frequency of total recordable injuries improved compared to the previous year. Wärtsilä continues to implement safety action plans to create and maintain a safe and healthy work environment. Wärtsilä's safety KPI's 1-6/2026 1-6/2025 Frequency of total recordable injuries (TRIF), for own employees 2.22 2.52 Number of Safety Walks 5,560 4,990 Ratio of front-line employees who have reported at least one near miss or hazard observation in the previous 12 months 75.5% 67.4% Total recordable injury frequency rate (TRIF) In line with the "Set for 30" target to achieve carbon neutrality in its own operations by 2030, Wärtsilä continues to implement renewable energy solutions across its sites. The company is assessing opportunities to expand on-site solar generation and replace existing heating systems with energy-efficient heat pumps. During the second quarter, solar panels were installed at the facility in Trieste, Italy. This installation is expected to generate approximately 400 MWh of electricity annually, covering more than 10% of the site's total electricity consumption. The project reflects Wärtsilä's ongoing efforts to increase self-generated renewable energy at site level. In addition, the company is progressing in its adoption of electric vehicles and continues to expand the charging infrastructure across its sites. Of the total engine megawatts that Wärtsilä has delivered during the past twelve months, 70% were alternative fuel capable in Marine, while 93% in Energy were gas and dual-fuelled. 3.00 TRIF 2.00 1.00 2022 2023 2024 2025 LTM Q2 2026 0.00 2.20 2.44 2.24 2.57 2.62 Wärtsilä above sector average in all relevant ESG indices and rankings Wärtsilä's ratings in the most relevant sustainable development indices and rankings: Rating Scale Wärtsilä score Sector average Year CDP D- to A Climate B Water C N/A 2025 Dow Jones* 0 to 100 62** 28 2025 Ecovadis 0 to 100 Bronze to Platinum 74 Silver N/A 2025 FTSE Russell 1 to 5 3.5 2.7 2025 MSCI CCC to AAA AAA AA 2025 Sustainalytics 100 to 0 23*** 32 2025 *Wärtsilä is listed in DJSI Europe **Percentile ranking in the sector: among the best 4% ***ESG risk rating is scored on 0-100 range, with 0 being the highest and 100 the lowest score ‌Reporting segment: Wärtsilä Marine MEUR 4-6/2026 4-6/2025 Change 1-6/2026 1-6/2025 Change 2025 Key figures Order intake 1,152 1,031 12% 2,176 1,968 11% 3,926 of which services 561 571 -2% 1,180 1,164 1% 2,242 of which equipment 591 460 28% 996 804 24% 1,684 Order book, end of period 4,260 3,586 19% 3,725 Net sales 882 862 2% 1,702 1,689 1% 3,494 of which services 545 569 -4% 1,053 1,099 -4% 2,222 of which equipment 337 293 15% 648 589 10% 1,272 Book-to-bill 1.31 1.20 1.28 1.17 1.12 Comparable operating result 124 114 9% 230 213 8% 443 % of net sales 14.0 13.2 13.5 12.6 12.7 Operating result 118 115 2% 221 210 5% 449 % of net sales 13.3 13.3 13.0 12.4 12.9 Order intake bridge MEUR 4-6/2026 1-6/2026 2025 1,031 1,968 Organic 12% 13% Acquisitions and divestments 0% 0% FX impact -1% -2% 2026 1,152 2,176 Quarterly development Net sales bridge MEUR 4-6/2026 1-6/2026 2025 862 1,689 Organic 3% 2% Acquisitions and divestments 0% 0% FX impact -1% -2% 2026 882 1,702 1,600 1,400 1,200 MEUR 1,000 800 600 400 200 4-6/2023 7-9/2023 10-12/2023 1-3/2024 4-6/2024 7-9/2024 10-12/2024 1-3/2025 4-6/2025 7-9/2025 10-12/2025 1-3/2026 0 16.0 14.0 12.0 10.0 8.0 6.0 4.0 2.0 4-6/2026 0.0 Order intake Net sales Comparable operating result, % of net sales Figures from 2023 restated to reflect the redefined organisational structure as of 1 January 2024, as the Exhaust Treatment and Shaft Line Solutions business units were moved from Marine Systems to Marine Power, and Marine Power changed its name to Marine.

Moreover, the continued introduction of protectionist trade policies has exacerbated this uncertainty. This has led to business operations globally being impacted by continued inflationary pressure, changing trade flows and volumes, tighter monetary policies, concerns over the health of the Chinese economy, rising protectionism, the sanctions in place and planned against Russia and various other nations, and rising international trade tensions. Together, these factors are contributing to uncertainty that may limit both the investment appetite and global economic growth. Escalation in any of the forementioned factors could result in increased uncertainty over future demand for the equipment and services provided by Wärtsilä. Furthermore, the volatility of the geopolitical environment, and the enforcement of sanctions or embargos, pose a risk to the company's customer relations and international business activities. With the rapidly growing use of data in shipping and shipbuilding, as well as in the energy markets, cyber threats can potentially result in various forms of financial, operational, or reputational damage to the business. Changes in the regulatory environment, financiers' policies, or market sentiment could negatively impact the availability and cost of financing for Wärtsilä and Wärtsilä's customers, which could result in a lower demand for Wärtsilä's solutions. Marine markets The shipping and shipbuilding markets are under pressure to find ways to increase their energy efficiency and to reduce carbon emissions in line with regional regulations, such as the EU's Fit for 55, China's new target for reducing the carbon intensity of international shipping, the revised greenhouse gas strategy from the International Maritime Organisation, green financing, and the individual sustainability goals of end-customers. This, coupled with shifting trade flows resulting from increased geopolitical tensions and disruptions at key waterways, may lead to increased costs for shipowners and operators that cannot be fully passed on to end customers. The elevated geopolitical tensions, including the emerging national interests in revitalising shipbuilding activity and ensuring security of supply, disruptions at key waterways, and the protectionist trade policies that create barriers to global trade, may lead to growing uncertainty and have a negative impact on global economic activity and growth. This could result in reduced demand for ship capacity, shifts in the global shipbuilding footprint and shipping trade flows, and higher inflationary pressure. The constraints on shipyard capacity, the development and deployment of sustainable future technologies and fuels, the need to find the optimal pace and timing of investments based on financial feasibility, and compliance with emission regulations may affect the investment appetite of ship owners and operators. This concerns both newbuilding programmes and the management of existing fleets, and may pose a risk of the global shipping fleet not reaching targeted emission reduction levels. A lack of clarity at the global level around decarbonisation-related regulations and financial incentives may lead to an increase in regional regulations that could add complexity and costs for shipping. Sufficient global availability of sustainable future fuels will be crucial for shipping to reach its decarbonisation targets. Without a secured supply and clear incentives to drive the uptake of sustainable fuels, ship owners and operators may postpone investments in the uptake of technology capable of using these fuels. This may lead to a slower increase in the production of these fuels, and ultimately slow the decarbonisation of shipping. Ship owners and operators, as well as shipyards, may face risks to their business profitability due to the limited ability or desire of people to travel, a lower demand for goods and services because of persistent high inflation, higher barriers to global trade or economic slowdown, as well as higher voyage, operating, and financing costs. Highly indebted ship owners, operators or shipyards may not withstand the potential risk of slower than expected growth in demand, higher financing costs, or a lowered credit rating. Uncertainty around the longer-term demand for crude oil, oil price volatility, and the pressure to decarbonise are pushing oil majors to re-evaluate their spending on exploration activities and operational costs. This may lead to lower future demand for offshore drilling or support assets, as well as having an impact on the related tanker ship fleet. It may also hinder newbuild investments, due to concerns regarding residual asset values. Energy markets The overarching trend in the energy markets is the transition to renewable energy sources, such as wind and solar. The pace of this shift is the principal driver in the growth of balancing technologies. New technology innovations, as well as the price and availability of fuels and raw materials, affect Wärtsilä's business. High and volatile gas prices directly impact the relative competitiveness of the portfolio against other generating technologies, especially in thermal baseload plants. Similarly, policies related to the energy and electricity markets have direct and indirect impacts on future energy capacity and the generation mix. For example, energy and climate policies may speed or delay the energy transition. Recent years have highlighted the impact of geopolitical tensions on energy market policy and investment decisions. Concentrated supply chains in some countries, and the tight competitive situation, impose direct risks for the energy markets. Energy commodities and supply chains have lately been at the heart of trade policies, presenting risks for all energy technologies. Rapid growth in demand for data centre power has led to heightened financing needs and increased complexity across the value chain. While the scale and scope of potential tariffs related to current US trade policy remain uncertain, they may impact Wärtsilä's businesses in the US energy markets. Competition between and among energy technologies presents price pressure. Uncertainty related to any of the aforementioned factors tends to delay investment decisions. General news coverage relating to safety issues may affect customer perceptions of product safety, which could have a negative impact on Wärtsilä's business. Legal cases The Group is a defendant in a number of legal cases that have arisen out of, or are incidental to, the ordinary course of its business. These lawsuits mainly concern issues such as contractual and other liability, labour relations, property damage, and regulatory matters. From time to time, the Group receives claims of different amounts and with varying degrees of substantiation. There is currently one unusually sizeable claim. It is the Group's policy to provide for amounts related to the claims as well as for litigation and arbitration matters when an unfavourable outcome is probable, and the amount of loss can be reasonably estimated. The annual report contains a more detailed description of Wärtsilä's risks and risk management. ‌Additional information Discontinued operations On 15 June 2026, Wärtsilä agreed to establish a joint venture with German company RCT Solutions GmbH for its global Energy Storage business. The ownership structure of the joint venture will be 50% RCT Solutions and 50% Wärtsilä. Closing of the transaction is expected in the third quarter of 2026 subject to regulatory and other customary conditions and approvals, as well as the arrangement of a financing package. The joint venture is expected to be loss-making in 2026, driven by recent low order intake, and costs related to transformation actions. Depending on the timing of closing, the impact on Wärtsilä's full-year 2026 operating result is expected to be EUR -40 to -50 million. The joint venture is expected to generate positive results towards the end of 2027. As of the second quarter of 2026, the Energy Storage business has been classified as assets held for sale and discontinued operations. Consequently, Energy Storage is excluded from the reported Group figures presented in this report, and the comparative figures have been restated to reflect its classification as discontinued operations. In April-June, the order intake for discontinued operations amounted to EUR 24 million (50), the order book at the end of the period was EUR 545 million (800), and the result for the period was EUR -7 million (1). In January-June, the order intake amounted to EUR 38 million (80) and the result for the period was EUR -4 million (-2). Further financial information relating to discontinued operations is presented in Note Discontinued Operations on page 28 of this report. Decisions taken by the Annual General Meeting Wärtsilä's Annual General Meeting was held on 12 March 2026 at Messukeskus, Helsinki. The Meeting approved the financial statements for the year 2025, reviewed the Remuneration Report 2025 for Governing Bodies, and discharged the members of the Board of Directors and the company's President & CEO from liability for the financial year 2025. Decisions taken by the Annual General Meeting can be seen from Wärtsilä's website . Dividend distribution The Annual General Meeting approved the Board of Directors' proposal that a base dividend of EUR 0.54 per share plus an extraordinary dividend of EUR 0.52 per share, totalling EUR 1.06 per share, shall be paid for the financial year 2025. The dividend shall be paid in two instalments. The first instalment of the base dividend of EUR 0.27 per share plus an extraordinary dividend of EUR 0.52 per share, totalling EUR 0.79 per share, was paid on 23 March 2026. The second instalment of EUR 0.27 per share shall be paid on 23 September 2026. Shares In January-June, the number of shares traded on Nasdaq Helsinki was 121,389,056 shares, equivalent to a turnover of EUR 4,163 million. Wärtsilä's shares are also traded on alternative exchanges, including Turquoise, BATS, Chi-X and CBOE DXE. The total trading volume on these alternative exchanges amounted to 64,098,667 shares. The number of Wärtsilä's shares outstanding as of 30 June 2026 was 589,546,248, and the number of treasury shares was 2,177,142. ‌Wärtsilä's Half-Year Financial Report January-June 2026 This half-year financial report is prepared in accordance with IAS® Standard 34 (Interim Financial Reporting) using the same accounting policies and methods of computation as in the annual financial statements for 2025, except for the new and amended IFRS® Accounting Standards stated below. All figures in the accounts have been rounded and consequently the sum of individual figures can deviate from the presented sum figure. This half-year financial report is unaudited. ‌Use of estimates Preparation of the financial statements in accordance with the IFRS Accounting Standards requires management to make judgements, estimates, and assumptions that affect the valuation of the reported assets and liabilities, as well as other information, such as contingent assets and liabilities and the recognition of income and expenses in the statement of income. Although these continuously evaluated judgements, estimates, and assumptions are based on management's past experience and best knowledge of current events and actions, as well as expectations of future events, actual results may differ from the estimates. For Wärtsilä, the most significant judgements, estimates, and assumptions made by the management relate to, for example, revenue recognition, especially project estimates for long-term projects and agreements, impairment testing, the valuation of trade receivables, contract assets and inventories, determining the length of lease terms, defined benefit pension obligations, measurement of warranty provisions and recognition of provisions for litigation, and uncertain tax positions. In addition, accounting for business combinations, and valuation of assets held for sale require use of estimates. ‌Organisational changes In June 2026, Wärtsilä announced plans to establish a joint venture for its global Energy Storage business. Consequently, Energy Storage has been classified as assets held for sale and discontinued operations, and it no longer constitutes an organisational unit or a reporting segment. The comparison figures for 1-3/2026 and 2025 have been restated to reflect the current organisational structure. The comparison figures for 2024 (available in Quarterly figures) have not been restated accordingly. ‌Own shares and equity-settled share-based payments At the beginning of 2026, the total amount of own shares held by the Company was 3,286,430. The shares are to be used for pay-outs under the share-based incentive programmes of Wärtsilä Corporation. During the year, 1,109,288 own shares were used to settle share-based payments, resulting in the total amount of 2,177,142 at the end of the reporting period. Wärtsilä has long-term incentive schemes, which can be settled in company shares. These contingently issuable ordinary shares and unvested shares are issuable when certain pre-defined conditions in the incentive programmes are met during a timeframe set in the conditions of the incentive programmes. If the settlement were to happen at the reporting date, it would result in issuing 1,708,496 shares. These shares are considered as potential ordinary shares causing dilutive effect on the EPS. Number of shares outstanding on 1 January 2026 588,436,960 Share-based payments settled in company shares 1,109,288 Number of shares outstanding on 30 June 2026 589,546,248 Weighted average number of shares outstanding during the period 589,025,312 Weighted average number of dilutive potential ordinary shares during the period Contingently issuable ordinary shares 1,195,057 Unvested shares 513,439 Weighted average number of shares outstanding during the period to be used in the calculation of diluted EPS 590,733,807 ‌New and amended Accounting Standards In 2026, the Group has adopted the following new or amended Accounting Standards issued by International Accounting Standards Board (IASB): Amendments to IFRS 9 Financial Instruments and IFRS 7 Financial Instruments: Disclosures clarify that a financial asset or liability is recognised or derecognised on the settlement date, and introduce an option to derecognise financial liabilities settled through electronic payment system at an earlier date if certain criteria is met. The amendments also clarify how to assess the contractual cash flow characteristics of certain financial assets, such as ESG-related, and affect disclosure requirements. The amendments do not have a significant impact on the consolidated financial statements. Other new or amended Accounting Standards already effective do not have a significant impact on the consolidated financial statements or other disclosures. In 2027 or later, the Group will adopt the following new or amended Accounting Standards issued by IASB: New Accounting Standard IFRS 18 Presentation and Disclosure in Financial Statements (effective for financial periods beginning on or after 1 January 2027) improves the quality of financial reporting by requiring defined subtotals in the statement of income and disclosure about management-defined performance measures, as well as adding new principles for aggregation and disaggregation of information. The standard requires that all income and expenses are classified into five categories in the statement of income: operating, investing, financing, income taxes, and discontinued operations. In addition, it is required to use the operating profit subtotal as a starting point for statement of cash flows. The standard changes the presentation of disclosed information and increases the amount of disclosed information and it has no impact on recognition or measurement. The Group is currently assessing the impact of IFRS 18 as it is expected that the standard will have a significant impact on the presentation of the statement of income. The primary identified areas of changes are the following: The share of profit from joint ventures and associates will be presented in the investing category instead of the operating category. Foreign exchange differences, and income and expenses related to cash and cash equivalents will be presented in the investing category instead of the financing category. Foreign exchange rate differences on intragroup loans and cash pooling arrangements are currently presented in the financing category. The presentation is currently under evaluation in the Group. Foreign exchange rate differences from external derivatives will be presented in the operating category, whereas currently financing-related portion of derivatives is included in the financial items and the rest in the operating result. The assessment may require judgments around aggregation and disaggregation of certain balances, as well as additional disclosures relating to management-defined performance measures. Other new or amended Accounting Standards not yet effective are not expected to have a significant impact on the consolidated financial statements or other disclosures. ‌Condensed statement of income

The ownership structure of the joint venture will be 50% RCT Solutions and 50% Wärtsilä. Closing of the transaction is expected in the third quarter of 2026 subject to regulatory and other customary conditions and approvals, as well as arrangement of a financing package. The impact of the transaction on the result for the reporting period is expected to be insignificant.

KGaA and business unit Water & Waste to Solix Group AB. Gas Solutions divestment was announced in December 2025 and Water & Waste in February 2026. Both business units belonged to Portfolio Business. In 2026, the net sales of Gas Solutions was EUR 244 million until disposed (394 million in 2025). The impact of the Gas Solutions divestment on the result for the reporting period 2026 is not estimated to be significant. Classifying Gas Solutions as assets held for sale had an impact of EUR -20 million on the result for the financial period 2025, which was recognised in the statement of income as depreciation, amortisation and impairment, and it was considered as an item affecting comparability. In 2026, the net sales of Water & Waste was EUR 20 million until disposed (54 million in 2025). The impact of the Water & Waste divestment on the result for the reporting period 2026 is not estimated to be significant. ‌Disaggregation of revenue Revenue from contracts with customers is derived over time and at a point in time from the following revenue types.

Product sales consist of sales of spare parts and standard equipment, for which the revenue is recognised at a point in time when the control of the product has transferred to the customer, in general upon delivery of the goods. Goods and services -type of revenue involves short-term field service jobs, including the delivery of a combination of service and equipment. The revenue is recognised at a point in time when the service is rendered. Projects are of both short- and long-term duration. Depending on the contract terms and the duration of the project, the revenue is recognised at a point in time or over time. In large-scale system or equipment deliveries which require engineering, for example power plants and gas solutions construction contracts, the revenue is recognised over time.
