Authorizing the Board of Directors to decide on a share issue and on granting option rights and other special rights entitling to shares

The Board of Directors proposes that the General Meeting authorize the Board to decide on a paid share issue and on granting option rights and other special rights entitling to shares as set out in Chapter 10, Section 1 of the Finnish Limited Liability Companies Act, or on the combination of some of the aforementioned instruments in one or more tranches on the following terms and conditions:

A maximum of 1,649,250 new and/or treasury shares of the Company (including shares to be issued based on special rights) may be issued under the authorization, which corresponds to approximately 10 per cent of all shares in the Company at the time of the convocation of the General Meeting.

Within the limits of the foregoing authorization, the Board of Directors is given the right to decide on all terms and conditions for issuing shares and granting option rights and other special rights entitling to shares. The Board of Directors is authorized to decide on the recording of the subscription price either as a share capital increase, or fully or partly in the reserve for invested unrestricted equity.

A share issue and the issuance of special rights entitling to shares may also take place as a directed issue in deviation of the shareholder’s pre-emptive right if the Company has a weighty financial reason for this under the Finnish Limited Liability Companies Act (directed issue). In that case, the authorization can be used to finance corporate acquisitions or other investments that are part of the Company’s business, to maintain and increase the Group’s solvency, to implement an incentive scheme, and to expand the ownership base and develop the capital structure.

The authorization revokes the authorization granted by the Extraordinary General Meeting on 23 December 2022 to issue special rights entitling to shares and the authorization granted by the Annual General Meeting on 16 April 2025 to issue shares and to grant option rights and other special rights entitling to shares.

The authorization is proposed to be effective until the close of the next Annual General Meeting, but no longer than until 30 June 2027.

Authorizing the Board of Directors to decide on the repurchase and/or on the acceptance as pledge of the Company’s own shares

The Board of Directors proposes to the General Meeting that the General Meeting authorize the Board of Directors to decide on the repurchase and/or on the acceptance as pledge of the Company’s own shares under the following conditions:

A maximum of 824,630 shares may be repurchased and/or accepted as pledge, which corresponds to approximately 5 per cent of all the shares in the Company at the time of the convocation of the General Meeting.

The shares will be purchased in trading organized by Nasdaq Helsinki Ltd at the market price on the date of repurchase.

Own shares may be repurchased and/or accepted as pledge in deviation from the shareholders’ proportional holdings (directed repurchase and/or directed acceptance as pledge) as set out in Chapter 15, Section 6 of the Finnish Limited Liability Companies Act.

The repurchase of shares reduces the Company’s unrestricted equity. The Board of Directors shall decide on the manner in which the shares are repurchased/or accepted as pledge.

The authorization is proposed to be effective until the close of the next Annual General Meeting, but no longer than until 30 June 2027.

CEO Kari Sundbäck

The year 2025 marked a period of strengthening and turnaround for Enersense. We focused our operations on growing market segments and on our strong areas of expertise in electricity and telecommunications networks and in the clean energy transition. Our EBIT improved, the relative profitability of our core businesses increased towards the end of the year and our order book grew. The order book of the Power Business Unit was record high at the end of the year. In line with our updated strategy, we aim to build lifecycle partnerships with our customers and increase shareholder value in a targeted manner.

The first half of 2025 was a period of strategic focusing: we successfully divested and discontinued operations that were not part of our core businesses and updated our strategy. In the second half, our strategy implementation progressed with good results; we grew our order book and renewed our operating model. In addition, we focused on strengthening our financial base and on improving profitability throughout the year. We signed a new financing agreement and streamlined our operations with the Value Uplift programme, which progressed better than expected and achieved an annual EBIT/EBITDA run-rate improvement of EUR 6.7 million.

In the midst of change, we have received encouraging feedback from our customers and employees. Our customers want us to provide easiness, transparency and increasingly comprehensive solutions for the entire lifecycle of their asset. These are the building blocks of our competitive advantage. Our customers also have a growing need to find concrete and effective ways to reduce their climate emissions and improve their carbon handprint. Our climate roadmap and the targets we set last year will improve our ability to advance our customers’ sustainability. In February 2026, we received approval for our climate targets from the Science Based Targets initiative.

Our employee engagement index improved, and according to our pulse survey, our strategy is perceived as understandable and timely. The improvement we made in work safety is particularly pleasing. The frequency of lost time incidents decreased by over a third. Our goal is to be a community chosen by experts, where we can continuously learn for tomorrow.

Financial turnaround proceeded well

Enersense’s EBIT improved by more than EUR 30 million to EUR 16.4 million in 2025, supported in particular by successful divestments. The restructuring and turnaround of the company were reflected in high adjustments and write-downs affecting comparability throughout the year. In December, we finalised a new financing arrangement. Our balance sheet is clearly stronger following the decrease in net gearing, and net debt is at low level of EUR 3.4 (30.6) million.

In our core businesses, the focus on selected customer segments and offering, a smaller project portfolio, and the completion of large Baltic projects in the comparison period were reflected in lower revenue, particularly in the early part of the year, but in the fourth quarter, revenue was already close to the comparison period’s level. Our operations are now fully in line with the new strategy. The order book grew from the second quarter onwards and increased to EUR 392 (387) million. The order book of our Power Business Unit was record high at the end of the year.

Despite the decline in revenue, adjusted EBITDA for the core businesses was EUR 18.8 million and relative profitability remained at the comparison period’s level. Relative profitability improved from the second quarter onwards and was clearly better in the fourth quarter than in the comparison period. The strong order book and measures taken to improve profitability provide a good foundation for 2026.

Good position at the heart of growing markets

We are among the three most significant players in our chosen markets and are constantly developing our expertise. Enersense’s markets are characterised by strong organic growth. All of our operating countries are investing heavily in the capacity and reliability of their electricity and telecommunications networks. The clean energy transition will inevitably progress, as it makes environmental and economic sense, is profitable, and enhances security of supply.

Investments in data centres are accelerating and significantly increasing demand for all our Business Units. There is strong investment particularly in electricity network capacity due to the demand created by data centres. We have already implemented data connections and district heating recovery for data centres, and our top-level expertise in substations, battery storage, electricity transmission networks and renewable energy is of interest to data centre developers. We see a lot of potential in this customer segment and a large part of our operations is already linked to data centres.

During the year, we have built a solid foundation for Enersense’s profitable growth and for increasing shareholder value. We will continue to improve our performance in 2026. For our achievements in 2025,

Enersense signs data centre infrastructure agreements in Latvia

Enersense International Plc | Press Release | February 11, 2026 at 14:45:00 EET

Enersense has signed its first agreements related to data centre infrastructure development in Latvia, marking an important milestone for the company’s operations in the country. Enersense will build the fibre connections and medium- and low-voltage power transmission lines required for the new data centre near Riga.

Enersense has entered into a construction work agreement with a Latvian state-owned energy company AS Latvenergo for the development of a fibre connection to a new large-scale data centre currently under construction in Salaspils, near Riga.

The agreement covers the construction of the fibre infrastructure required for the facility.

Earlier in January, Enersense signed a construction agreement with the Latvian electricity distribution system operator AS Sadales Tīkls for the development of new medium- and low-voltage power transmission lines to the same data centre.

The main scope of work includes the construction of a 3.5 km medium-voltage transmission line and a 2.0 km fibre connection, as well as the installation of disconnectors and switchgear equipment.

Building on successful data centre projects in Finland

Enersense has previously delivered data connectivity solutions and district heat recovery systems for data centres in Finland.

“This project represents an important step for Enersense in Latvia, as it marks our entry into data centre infrastructure projects. It demonstrates our capability to deliver reliable power line and fibre connection solutions for critical infrastructure, while also highlighting the strong expertise of our local team and their ability to meet demanding qualification and technical requirements,” says Arnis Odiņš, Head of Enersense Latvia.

“Our extensive expertise in substations, battery energy storage, power transmission networks and renewable energy solutions is highly relevant to data centre developers. We see significant potential in this segment, and a considerable share of our operations is already directly or indirectly linked to data centres,” Odiņš adds.

Enersense builds high-voltage transmission line using low-carbon concrete

Enersense is constructing a 400 kV high-voltage transmission line in northern Finland for the transmission system operator Fingrid, using low-carbon concrete elements in the foundations. To the best of current knowledge, this is the first time low-carbon concrete structures have been used in the construction of a high-voltage electricity network in Finland. The pilot is being carried out in collaboration with the precast concrete manufacturer Consolis Parma.

Concrete plays a key role in grid construction and is used in almost all foundations of high-voltage transmission towers. In total, the project covers approximately 117 kilometres of transmission line, around one third of which will be built using low-carbon concrete elements.

The project will utilise nearly one thousand low-carbon concrete elements, requiring more than two million kilogrammes of low-carbon concrete in their manufacture. The construction process remains unchanged: the elements are cast at the factory and installed underground on site, after which the towers are erected on top of the foundations. The elements are produced at Parma’s Oulu factory.

“Cement production is a significant source of emissions, and we are continuously seeking new ways to reduce emissions from construction in order to support our customers in achieving their sustainability targets. The use of lower-carbon concrete is one example of how we can strengthen our customers’ positive environmental impact while also setting an example for the industry and society through more environmentally friendly construction. Pilots of this kind are important for Finland’s carbon neutrality goals,” says Santeri Hirvonen, Director of Transmission Line Construction Finland at Enersense.

Low-carbon concrete elements reduce emissions by 15 per cent

The foundation elements are manufactured as PARMA Green products in accordance with the low-carbon classification of the Finnish Concrete Association, using a concrete mix with emissions 15 per cent lower than the standard level. The use of low-carbon concrete mixes requires third-party certification from the manufacturer.

“Our environmental development work focuses on the manufacture of low-carbon products, energy efficiency and the circular economy. Our climate target is to reduce our emissions by five per cent annually and to halve them by 2035,” says Juha Rämö, Chief Technology Officer at Consolis Parma.

“Last year, more than half of our production consisted of low-carbon PARMA Green products. In this transmission line project, carbon dioxide emissions will be reduced by nearly 50,000 kilogrammes thanks to the low-carbon alternative,” Rämö adds.

The end customer for the project is Finland’s transmission system operator, Fingrid.

Enersense aiming for a 40% reduction in emissions by 2035

Enersense International Plc | Press Release | February 11, 2026 at 08:30:00 EET

Enersense is committed to reducing the emissions from clean energy transition and telecommunications networks. The company’s target is to reduce its total emissions by 40% by 2035 from 2023. In February, Enersense had its target approved by the Science Based Targets initiative (SBTi). More than 90% of Enersense’s emissions originate from purchased materials and services, so action is needed throughout the value chain to reduce emissions.

“We are determined to reduce climate emissions – both our own and those of our customers. That is why we have integrated science-based emission reduction targets into all our operations. The climate target approved by the international Science Based Targets initiative is one of our key strategic objectives alongside our financial targets, and external validation increases the transparency of our climate work,” says Liisi Tamminen, Enersense’s Head of Communications and Sustainability.

Enersense’s climate targets for 2035 approved by SBTi:

Absolute GHG emissions (Scope 1–2) from own operations -63% from the 2023 baseline
Absolute GHG emissions from the value chain (Scope 3) -38% from the 2023 baseline
Combined, these targets will reduce Enersense’s emissions by 40%

The greatest impact on emissions from increasing the use of low-carbon steel

More than 90% of Enersense’s emissions originate from sources other than the company’s own operations, so-called Scope 3 emission sources. The greatest single source of emissions is steel used in green energy transition projects, such as power lines and substations. Steel accounts for about one-third of the company’s emissions. Enersense has drawn up a climate roadmap that defines the actions needed to achieve emission reductions.

“The shift to low-emission steel, the electrification of our vehicle fleet and getting our material and service suppliers committed to emission reduction are the keyways to achieve our climate targets. We have identified numerous ways to reduce emissions from the investments, operation and maintenance of clean energy transition and telecommunications networks. We do not yet have all the solutions for reducing emissions, so we are open to innovation and new ways of working,” says Tamminen.

Enersense collaborates with WWF Finland to increase demand for low-emission steel. By offering more climate friendly materials, Enersense can also help its customers to reduce their emissions and improve their carbon handprint.

Enersense Climate Roadmap

Enersense continues as Helen’s district heating operations and maintenance partner

Enersense International Plc | Press Release | February 10, 2026 at 08:30:00 EET

Enersense and energy company Helen have agreed to extend their operations and maintenance contract for the years 2027–2028. Enersense has been operating and maintaining Helen’s power plants and district heating and cooling network since 2022. Under the contract, the company will continue to support Helen in its clean energy transition. The newly signed two-year agreement continues this cooperation and was included as an option in the original contract.

“We thank Helen for their trust and for the opportunity to continue our cooperation. Helen is delivering Finland’s most impactful energy transition, and we are committed to continuously improving our work to advance it,” says Mikael Vainionpää, Enersense’s EVP, Energy Transition Business Unit.

In accordance with the cooperation agreement, Enersense will continue to develop its operation and maintenance services as well as personnel, as new forms of energy production require new expertise. Approximately 150 Enersense employees work on the Helen account. In line with its strategy, Enersense acts as Helen’s partner across the entire energy production lifecycle.

“Over the past few years, we have reduced our emissions at a very rapid pace, with emissions already more than 80 per cent lower than in 1990. As the most significant demonstration of our transformation, we closed our last coal-fired power plant in Salmisaari last spring, bringing the use of coal in our energy production to an end. High-quality operation and maintenance services are a prerequisite for delivering an energy transition of this scale and speed,” says Timo Aaltonen, SVP, Heating and cooling at Helen.

“A sustainable society of the future runs on clean energy. We have supported Helen in transitioning away from coal, improved cost efficiency and increased the use of digitalisation and artificial intelligence in operation and maintenance. We will apply these lessons and continue to develop the society of the future in our capital city,” Vainionpää says.

The value of the agreement is over EUR 30 million, and it will be recorded in the Energy Transition Business Unit’s order book for the first quarter of 2026.

Enersense and WWF Finland launch collaboration to accelerate demand for low-emission steel

Enersense International Plc | Press Release | January 29, 2026 at 09:00:00 EET

Enersense and environmental organisation WWF Finland are launching a collaboration aimed at accelerating demand for low-emission steel. Steel is one of the largest sources of emissions in the construction of electricity and telecommunications networks, making the shift to low-emission solutions essential for achieving climate targets. The year-long collaboration aims to support more climate-smart choices in construction projects that require steel.

Through the collaboration, Enersense will be better equipped to support its customers in choosing low-emission steel, thereby reducing emissions and improving its carbon handprint. Globally, the steel production value chain accounts for almost ten per cent of all CO2e-emissions. However, low-emission production technologies already exist. Strong demand signals can accelerate investments in new fossil-free production facilities.

“Reducing emissions from steel requires action across the entire value chain. Steel is one of the most efficiently recycled materials in the world, but recycling alone is not enough. Steel plants should transition to using renewable electricity. We are also eagerly awaiting the completion of green steel production investments, which would enable electricity and telecommunications networks to be built using near-zero-emission steel. There is still some way to go, so through our collaboration with WWF Finland we are increasing demand for low-emission steel by supporting our customers in procuring genuinely lower-emission solutions,” says Liisi Tamminen, Head of Communications and Sustainability at Enersense.

The decarbonisation of steel production has been one of WWF Finland’s climate priorities for several years. WWF Finland also leads WWF’s international steel programme. WWF Finland brings deep expertise on the steel market and its environmental impacts across the entire supply chain to the collaboration. It also supports Enersense in advancing practical climate action and acts as the company’s expert partner.

Enersense has already piloted the use of low-emission steel in construction. The company is currently, for the first time in Finland, building substations that utilise recycled steel in their structures. The carbon dioxide emissions of this steel are on average around 40 per cent lower compared with conventional steel.

Enersense aims to reduce emissions from clean energy transition and telecommunications network investments

“Enersense is a pioneer in the use of low-emission steel in substation construction, and through our collaboration we can boost impactful climate action in other construction projects as well. Initiatives like this are crucial for enabling the entire market to shift towards more sustainable choices,” says Bernt Nordman, Programme Director, Climate Programme at WWF Finland.

In addition to regular dialogue, the collaboration will produce a practical guide for buyers of low-emission steel and a joint event focusing on the benefits and procurement of low-emission steel.

“We have set ambitious, science-based emission reduction targets, and achieving them requires strong expertise and concrete actions. Our goal is that investments in clean energy transition and telecommunications networks can in future be carried out with lower emissions than before. We are pleased to see that our customers are highly interested in low-emission alternatives,” Liisi Tamminen says.

A new digital way of working can cut fibre connection delivery times by up to half

Enersense International Plc | Investor News | December 17, 2025 at 08:30:00 EET

Enersense is digitalising its fibre construction operations. For customers, this means faster service; for installers, a smoother everyday working life. The change represents a major commitment by Enersense to transform the way it operates.

Building a fibre network requires many specialists: designers whose plans guide the installers’ work, project managers who track schedules, and procurement experts responsible for materials. A single site can involve thousands of events and milestones, which are difficult to manage without comprehensive oversight. Clear scheduling and control of progress are essential for both installers in the field and partners and customers alike. There are many moving parts.

Enersense is streamlining this complex puzzle with a new digital way of working.

The company’s partner in this transformation is Sitetracker, the global leader in complete Asset Lifecycle Management. As industry needs are constantly evolving and rigid systems can become bottlenecks, Enersense and Sitetracker are developing both the platform and the way of working together.

“In our strategy, we have decided to differentiate through transparency and efficiency delivered to the customer. This new digitalised way of working is a concrete step in the right direction. It is also a significant commitment to change for us,” says Miika Erola, EVP, Connectivity at Enersense.

When data from different phases of a project is brought together in one place, the process becomes transparent. Thanks to the new digital way of working, customers can see in real time how the fibre network is progressing.

“In services where the new model is in use, delivery times to customers have in some cases been cut by up to half,” Erola says.

An easier and more secure working day for installers without paperwork

The new digital system works like a car dashboard and is easy to use. Installers can clearly see which task comes next and mark it as completed once it is done. Everyone involved in the project can follow progress and anticipate their own actions. The system guides work in the correct order and reminds users of things that are easily forgotten on a busy day.

In an industry where pen and paper are still common and information is scattered across multiple places, the change is significant.

“Previously, installers might have noted completed tasks in their own Excel files or notebooks. Now all information is securely stored on a single mobile platform. Thanks to the platform, critical risk assessments cannot be overlooked. The chain works safely, as it should,” Erola says.

The working day becomes easier when daily tasks are visible directly on the platform. Unnecessary trips are reduced, as the right tools are taken along from the start of the day. Employee wellbeing can also be better supported when workloads are visible and it is easier to assess how much input is needed from each person and where.

At present, the new way of working is being rolled out in the project management of construction services. According to Erola, the aim is to expand it in the future to all Enersense field work and work phases across different business areas and countries of operation.

“We are excited about this. We want to be both a reliable partner for our customers and an attractive employer for skilled professionals, and this new way of working supports both.”

Enersense is building a substation in Halsua as part of OX2’s major wind power investment

Enersense International Plc | Investor News | December 16, 2025 at 09:30:00 EET

Enersense has won the contract to build a new 400/30 kV substation for the Kannisto wind farm in Halsua, Central Ostrobothnia. The substation is part of OX2’s extensive programme, which includes three major wind farm projects in Southern Ostrobothnia, Finland.

A total of 20 turbines will be built for the Kannisto wind farm. Due to the scale of the project, the connection will be made directly to Fingrid’s 400 kV transmission grid, which requires a separate substation where the electricity produced by the turbines is converted to the grid’s voltage level. In addition, a new transmission line will be built from the substation to Fingrid’s station.

Enersense’s contract includes the design, procurement, construction, installations, testing and commissioning of the substation.

“We have solid experience in substation projects across Finland, and we will bring all this expertise to the Kannisto project as well. We are looking forward to working together and getting the project started,” says Anssi Niiles, Vice President of Enersense’s substation business.

Renewable energy projects are important for Finland

Wind power investments strengthen Finland’s energy self-sufficiency, reduce emissions and support the shift towards affordable, clean electricity. Large-scale new projects are also significant regional investments that create jobs and accelerate the modernisation of the electricity system.

“It’s great to be back in the renewable energy market. The sector has been somewhat quieter in recent years, so new investments are very welcome to support the growth of carbon-neutral electricity. We are grateful to OX2 for their trust,” says Sirpa Smids, Enersense’s Director of Renewables.

The contract will be recorded in the order backlog of Enersense’s Power Business Unit for the fourth quarter of 2025. Design work on the substation will begin in January 2026, and the substation will be commissioned at the end of 2027.

Sami Lahtinen’s blog: A company cannot move forward by using yesterday’s methods

If we want something to happen, it must be someone’s job. We’ve repeated this idea throughout the year as part of Enersense’s strategy work. Leading development and ways of working is work, too. Data alone won’t drive improvement; it must be turned into action.

I lead Enersense’s brand-new Business Development, Enersense Way & IT unit.

Our updated purpose is: Delivering the essentials of tomorrow’s society. If we want to live up to that promise, we must evolve for the future. Our customers expect it as well. For instance, we have ambitious emission-reduction targets that we proudly present to our customers. Reaching them simply isn’t possible without continuous development. At the same time, we aim to be an efficient and proactive partner for our customers.

Many organisations have a role or team dedicated to development. Enersense’s solution is a unit that brings together more than twenty experts in strategy, way of working, sales and digitalisation. The unit also includes new Centres of Expertise (CoEs), which build a unified way of working across our businesses. They ensure we develop the competencies and methods needed in the market efficiently and collaboratively.

Our data and IT specialists are part of the development unit, as our strategy centres on digitalising our delivery models to stand out through efficiency and transparency. Our unit is filled with experts who get excited about digital solutions that enhance efficiency, transparency and productivity.

Development is born from data, but it lives through culture

We’re at the cusp of a major shift. We’ve traditionally done many things in a decentralised way, and now we’re building a unified way of working based on six cornerstones: organisational structure, roles, processes, metrics, IT systems and data utilisation – while recognising the competitiveness factors of each market. When our operating model is consistent across the business, we benefit from scale. Ultimately, our aim is quite simple: to increase the value delivered to customers in every market, smartly and competitively.

But none of these plans will succeed without a strong company culture.

A shared operating model works when we know one another and build trust together. That’s why I hope my team forms strong networks within the organisation.

I have many years of leadership experience. It’s valuable, of course, but it also comes with a risk: am I able to renew myself and listen? When culture evolves, leaders must evolve with it. Our unit serves as a bridge between strategy, digitalisation and business. Our task is to help Enersense understand the direction the world is heading.

When business and development move forward together, we can deliver the essential functions of tomorrow’s society that we promise our customers.

As previously announced by Enersense International Plc (“Enersense” or the “Company”) through a stock exchange release on December 4, 2025, the Board of Directors of the Company has resolved to amend the terms and conditions governing special rights relating to its convertible notes (the “Notes”), and to issue 40 additional special rights entitling to shares of the Company referred to in Chapter 10 Section 1 of the Finnish Companies Act. The resolutions were made on the basis of the authorization granted by the Extraordinary General Meeting held on December 23, 2022, to the extent applicable, and on the basis of the authorization granted by the Annual General Meeting held on April 16, 2025.

The additional special rights were issued in deviation from the shareholders’ pre-emptive rights (directed issue) for no consideration to the subscribers of the additional convertible capital notes (the “Subsequent Notes”) in a total nominal amount of EUR 4,000,000 issued as a tap issuance (the “Tap Issuance”) under the amended terms and conditions of the Notes. The special rights are attached to the Subsequent Notes and cannot be separated from the Subsequent Notes.

Following the execution of the Tap Issuance, the total nominal amount of the Notes issued under the amended terms and conditions of the Notes is EUR 30,000,000. The maximum number of new shares to be issued based on the special rights attached to the Notes is 4,285,714 shares.

The amendments to the terms and conditions governing special rights and the additional special rights entitling to shares have been registered in the Finnish Trade Register today on December 5, 2025.

Enersense will design and build telecommunication towers in Northern Lithuania

Enersense International Plc | Investor News | December 05, 2025 at 08:30:00 EET

Enersense has signed an agreement with Lithuania’s VŠĮ Plačiajuostis Internetas, the state-owned organisation responsible for developing Lithuania’s broadband infrastructure, for the design and construction of telecommunications towers. The towers form part of Lithuania’s nationwide programme to expand high-speed broadband infrastructure.

The towers are steel lattice communication structures that form part of Lithuania’s essential digital infrastructure.

Enersense is responsible for the full designing and building of the towers, covering everything from preparing the working and technical designs to constructing the foundations, steel structures, electrical installations, and the required telecommunications and security systems.

“We have strong expertise and long-standing experience in delivering projects of this kind, and we are pleased to bring that capability to this project as well. We would like to thank the customer for their trust in Enersense,” says Enersense’s director of mobile services Mika Homi.

This agreement represents a major national infrastructure project for Lithuania. It covers several tower sites across multiple municipalities, and requires complex technical design, multidisciplinary engineering work, and full statutory completion. According to Lithuanian legislation, these towers are considered special engineering structures.

In the Lithuanian telecom civil engineering market, a multi-million-euro design and build programme of this scale is regarded as a significant undertaking.

“The contract is also important for Enersense, supporting our new strategy and our ambition to expand our operations in the Baltic region further”, Homi says.

The project will start in early 2026 and is expected to be completed during the same year. The value of the project is approximately EUR 8 million, and it will be recorded in Enersense’s Connectivity Business Unit’s order backlog for the fourth quarter.

NEITHER THIS ANNOUNCEMENT NOR ANYTHING CONTAINED HEREIN SHALL FORM THE BASIS OF, OR BE RELIED UPON IN CONNECTION WITH, ANY OFFER OR COMMITMENT WHATSOEVER IN ANY JURISDICTION.

Enersense International Plc | Stock Exchange Release | December 04, 2025 at 19:00:00 EET

Enersense International Plc (“Enersense” or the “Company”) announced the positive results of the noteholders’ meeting held today on December 4, 2025 relating to the consent solicitation in respect of its outstanding EUR 26,000,000 senior unsecured fixed rate 7.00% convertible notes due 2027 (ISIN FI4000541826) (the “Notes”). At the meeting, the holders of the Notes resolved to approve the Company’s proposal on amending the terms and conditions of the Notes (the “Proposal”) in relation to the amendment of the Notes into a subordinated hybrid convertible bond.

Following the passing of the Proposal, Enersense has resolved to issue additional convertible capital notes (the “Subsequent Notes”) in the aggregate nominal amount of EUR 4,000,000 to selected professional investors as a tap issuance under the amended terms and conditions of the Notes (the “Tap Issuance”). The net proceeds of the Tap Issuance will be used for general corporate purposes. The issue date of the Subsequent Notes is expected to be on or about December 11, 2025 and the issue price will be 100%.

Pursuant to the amended terms and conditions of the Notes, the Subsequent Notes will initially bear a fixed coupon, payable semi-annually in arrears. The coupon will be 7.0% per annum until January 15, 2026 and, thereafter, 8.0% per annum until January 15, 2029. From January 15, 2029 onwards, interest on the Subsequent Notes will be determined by reference to the 3-month Euribor plus a margin of 10.708% per annum, payable quarterly in arrears.

In connection with the execution of the Tap Issuance, the Board of Directors of the Company has, based on the authorization granted by the Annual General Meeting held on April 16, 2025, resolved to issue 40 special rights entitling to shares of the Company referred to in Chapter 10 Section 1 of the Finnish Companies Act (624/2006, as amended) to enable the conversion of the Subsequent Notes into shares in accordance with the amended terms and conditions of the Notes. The special rights were issued in deviation from the shareholders’ pre-emptive rights (directed issue) for no consideration to the subscribers of the Subsequent Notes in the Tap Issuance. The special rights are attached to the Subsequent Notes and cannot be separated from the Subsequent Notes.

A special right is attached to each Subsequent Note with a nominal value of EUR 100,000. Each special right entitles to 14,285.71 (not exact number) new shares of the Company. The initial conversion price per share has been set at EUR 7.00 as set forth in the amended terms and conditions of the Notes. Based on the initial conversion price, the conversion of all the Subsequent Notes would result in the issue of a maximum of 571,428 new shares in the Company, representing in total approximately 3.5% of the current total amount of shares in the Company (approximately 3.3% on a fully diluted basis). Adjustments may be made to the conversion price, as further described in the amended terms and conditions of the Notes. Should adjustments be made to the conversion price, requiring an increase of the number of shares to be issued, a separate resolution will be made as required by the Finnish Companies Act to increase of the number of shares.

The Board of Directors considered that there are weighty financial reasons for the issuance of special rights in respect of the Subsequent Notes in the Tap Issuance, because the execution of the Tap Issuance strengthens the Company’s balance sheet, prolongs its maturity profile and supports the refinancing of the Company’s other debt financing facilities.

No application has been made or is currently contemplated to be made to list the Subsequent Notes or admit them to trading on any market. The additional special rights entitling to shares are expected to be registered in the Finnish Trade Register in early December.

Nordea Bank Abp is acting as the Lead Arranger and Bookrunner and Danske Bank A/S as the Arranger and Bookrunner for the Tap Issuance.

“The completed financing arrangement for approximately three years has a significant positive impact on Enersense’s financial position and its ability to implement the lifecycle partner strategy published in the summer. I would like to thank our financiers for their trust in our company’s operations. Taking into account the effect of the financing arrangement, unofficial pro forma figures at the end of September 2025 (figures reported in the January–September Business Review in parentheses) would have been: interest-bearing net debt EUR 8.9 (38.5) million, net gearing 14.0 (98.9) percent, and equity ratio 37.6 (22.9) percent,” says Kari Sundbäck, CEO of Enersense.

The Amendments have become effective immediately after the passing of the Proposal at the Meeting.

As compensation to the noteholders approving the Proposal, Enersense shall pay instruction fee to noteholders who submitted a valid voting instruction in favour of or against the Proposal prior to 4:00 p.m. (EET) on November 26, 2025. Such noteholders are eligible to receive a fee of 0.20 per cent of the principal amount of the Notes which are subject of the voting instructions (the “Instruction Fee”). The Instruction Fee shall be paid to eligible noteholders’ bank accounts as provided in the voting instructions no later than ten (10) business days after the Meeting.

The noteholders are requested to contact Nordea Bank Abp as the Lead Solicitation Agent and Danske Bank A/S as the Solicitation Agent (contact details below) for questions relating to the consent solicitation.

Solicitation Agent, Danske Bank A/S, e-mail: liabilitymanagement@danskebank.dk,

Attention: Debt Capital Markets, tel. +45 3364 8851

In addition, Enersense expects to issue additional convertible capital notes in the aggregate nominal amount of up to EUR 4,000,000 in the near term. The additional convertible capital notes would be issued to selected professional investors as a tap issuance under the amended terms and conditions of the Notes. The net proceeds of the potential issuance of additional convertible capital notes would be used for general corporate purposes.

Amendments to the terms and conditions governing special rights

As announced on November 17, 2025, the Amendments also included the change in the initial conversion price from the current EUR 8.00 to EUR 7.00, representing a premium of approximately 57.9% to the arithmetic average of the volume weighted average price of Enersense’s shares on the official list of Nasdaq Helsinki Ltd on each of the 10 trading days prior to the launch of the consent solicitation, representing EUR 4.4329. Based on the initial conversion price, the conversion of all the Notes would result in the issue of a maximum of 3,714,285 new shares in the Company, representing in total approximately 22.5% of the current total amount of shares in the Company (approximately 18.4% on a fully diluted basis). The Board of Directors’ resolution to amend the initial conversion price, and as a consequence thereof, to increase the maximum number of new shares to be issued pursuant to the amended terms and conditions of the Notes, was made on the basis of the authorization granted by the Extraordinary General Meeting held on December 23, 2022, to the extent applicable, and on the basis of the authorization granted by the Annual General Meeting held on April 16, 2025.

The Board of Directors considered that there are weighty financial reasons for the amendment of the initial conversion price, because the implementation of the Amendments, taken as a whole, strengthens the Company’s balance sheet, prolongs its maturity profile and supports the refinancing of the Company’s other debt financing facilities, and is therefore in the best interests of the Company.

The amendments to the terms and conditions governing special rights are expected to be registered in the Finnish Trade Register in early December.

New Financing Arrangements

In addition, the new financing arrangements include committed guarantee lines amounting to EUR 40 million at maximum.

Enersense International Plc (“Enersense” or the “Company”) announces a consent solicitation in respect of its outstanding EUR 26,000,000 senior unsecured fixed rate 7.00% convertible notes due 2027 (ISIN FI4000541826) (the “Notes”) to solicit consents to amend the terms and conditions of the Notes (the “Proposal”) in relation to a contemplated amendment of the Notes into a subordinated hybrid convertible bond in order to strengthen the Company’s balance sheet, prolong its maturity profile and support the refinancing of the Company’s other debt financing facilities.

Pursuant to the Proposal, the Notes would initially bear a fixed coupon, payable semi-annually in arrears. The coupon would be 7.0% per annum until January 15, 2026 and, thereafter, 8.0% per annum until January 15, 2029. From January 15, 2029 onwards, interest on the Notes would be determined by reference to the 3-month Euribor plus a margin of 10.708% per annum, payable quarterly in arrears. The contemplated amendment of the terms and conditions of the Notes also includes the change in the initial conversion price from the current EUR 8.00 to EUR 7.00, representing a premium of approximately 57.9% to the arithmetic average of the volume weighted average price of Enersense’s shares on the official list of Nasdaq Helsinki Ltd on each of the 10 trading days prior to the launch of the consent solicitation, representing EUR 4.4329. Based on the proposed initial conversion price, the conversion of all the Notes would result in the issue of a maximum of 3,714,285 new shares in the Company, representing in total approximately 22.5% of the current total amount of shares in the Company (approximately 18.4% on a fully diluted basis).

Enersense commences a consent solicitation process and convenes a meeting of noteholders to be held at 9:00 a.m. (EET) on December 4, 2025 at the offices of Nordea Bank Abp at the address Aleksis Kiven katu 5, FI-00500 Helsinki, Finland (the “Meeting”) to resolve on the Proposal. The notice of the Meeting (the “Notice”) is attached hereto. Nordea Bank Abp is acting as the Lead Solicitation Agent, Danske Bank A/S as the Solicitation Agent and Nordic Trustee Oy as the Tabulation Agent in the consent solicitation process.

Certain existing holders of the Notes, representing in aggregate approximately 80 per cent of the nominal amount of the Notes, are expected to support the Proposal.

In addition, subject to the passing of the Proposal, Enersense may consider the issuance of additional convertible capital notes in the aggregate nominal amount of up to EUR 4,000,000. The additional convertible capital notes would be issued to selected professional investors as a tap issuance under the amended terms and conditions of the Notes. The net proceeds of the potential issuance of additional convertible capital notes would be used for general corporate purposes.

New Financing Arrangements

In connection with the planned amendments to the terms and conditions of the Notes, the Company has received credit commitments for new senior secured financing comprising of a EUR 16 million term loan and EUR 8 million revolving credit facility, both maturing in 2028. The new financing arrangements and the planned amendments to the terms and conditions of the existing Notes will extend the maturity profile of the Company’s financing. The proceeds from the new financing arrangements will be utilised to refinance the Company’s existing borrowings and repay the existing payment arrangement with the tax administration. The validity of the new credit commitments for the new financing arrangements is contingent on the passing of the Proposal.

Consent Solicitation

In the consent solicitation process, Enersense will offer instruction fee to noteholders who submit a valid voting instruction in favour of or against the Proposal prior to 4:00 p.m. (EET) on November 26, 2025 (the “Instruction Fee Deadline”). Such noteholders are eligible to receive a fee of 0.20 per cent of the principal amount of the Notes which are subject of the voting instructions (the “Instruction Fee”).

A noteholder who (i) submits voting instructions received after the Instruction Fee Deadline, (ii) votes at the Meeting in person or by proxy or (iii) does not follow the procedure for submitting voting instructions set out in the consent solicitation memorandum will not be eligible to receive the Instruction Fee. No Instruction Fee shall be paid to such noteholders who do not vote prior to the Instruction Fee Deadline.

Payment of the Instruction Fee is subject to the resolution approving the Proposal being duly passed by the Meeting and having become effective in full in accordance with its terms. The Instruction Fee shall be paid to eligible noteholders’ bank accounts as provided in the voting instructions no later than ten (10) business days after the Meeting wherein the resolution approving the Proposal is passed.

Enersense International Oyj Notice Of Meeting

Juha Silvola’s blog: high quality alone is no longer enough

It’s been almost six months since Enersense published its updated lifecycle strategy, which gives us a clear direction towards 2028. In the Power Business Unit, we have been determinedly putting this strategy into action. When I look around at my colleagues, I feel genuinely proud.

Our goal is to bring value to our customers throughout the entire lifecycle of their investments – and beyond. I want to remind us all that this value is more than just financial; we also help our customers reach their climate and sustainability targets.

I lead the Power Business Unit, where we design, build and maintain transmission networks, substations, wind and solar power parks, and energy storage systems. We have a strong foothold in Finland and are a growing player in Sweden and the Baltics, especially in transmission networks. By 2028, our goal is to be a lifecycle partner known for our digital maintenance solutions and our commitment to advancing our customers’ sustainability.

Our customers choose us because we offer efficiency, competitive pricing, and consistent quality. But the world has changed, and that is no longer enough.

Growing our customers’ carbon handprint

From now on, we also want to help our customers increase their carbon handprint. We will offer them low-emission material alternatives. For example, our customer Fingrid, the Finnish transmission system operator, has already ordered substations from us that are built using recycled steel. Low-carbon concrete has also made its way into our transmission line structures. We are constantly looking for new ways to use more low-emission materials.

I believe demand for low-emission solutions will only continue to grow. They are not just required by the EU, but also embedded in the strategies of many of our customers. It is increasingly important for companies to take real responsibility for reducing emissions, regardless of the EU’s direction.

The market situation, including the growth of renewable energy and grid companies’ investments, provides a strong foundation for the new Power strategy. Recently, we have won a 100-kilometre transmission line construction project in Central Finland and the largest substation project in our history in Nokia. We are also building transmission networks in Estonia and Lithuania, and we are bringing our expertise to data centres as well. We have the expertise, but we cannot become complacent. We must achieve our emission reduction targets and succeed in building a world-class safety culture. Trust must be earned again and again.

At the moment, we are preparing our business planning for 2026 – for the first time with our new organisation and operating model. When I look at my colleagues, I feel genuinely proud. We have succeeded in engaging our people in implementing the new strategy. Colleagues from different countries and units are working together in new ways. The expertise and enthusiasm are visible in every meeting I’ve attended. The strategy has truly come to life in our everyday work.

What motivates me is the thought that, by 2028, together with our customers, we can say: we were part of building a new, low-emission society. I truly believe that together we can achieve both goals – sustainable business and a low-emission future.

Recycled steel used in substation structures in Satakunta for the first time in Finland

Enersense International Plc | Investor News | November 03, 2025 at 08:10:00 EET

Enersense is constructing the steel structures of Fingrid’s Kokemäki, Harjavalta and Nakkila substations using recycled steel, which has around 40% lower emissions than conventional steel. The recycled steel has now arrived on site, and construction has begun.

The new substations will replace existing ones that have reached the end of their operational life. Recycled steel will be used, among other things, in the 110-kilovolt transmission line gantries where overhead lines are converted into underground cables.

Recycled steel will also be used for the outdoor masts supporting lightning protection and area surveillance systems. In addition, the switchgear will be built entirely without SF6 insulating gas, which is a potent greenhouse gas. The substations in Satakunta will feature so-called gas-insulated switchgear located indoors.

“For the first time in Finland, all outdoor steel structures of a main grid substation are being built from low-emission steel. It’s great to be piloting something new while at the same time helping to reduce both our client’s and our own value chain’s carbon footprint,” says Enersense’s Project Manager Sami Lehtimäki.

A total of over 80,000 kilograms of recycled steel will be delivered for the three substations.

Enersense assessed nearly a hundred suppliers to find suitable steel

Enersense’s experts conducted a comprehensive review of almost one hundred suppliers around the world to identify a suitable low-emission steel producer for substation construction.

“We aim for significant emission reductions throughout our value chain and want to help enhance our clients’ carbon handprint at the same time. We are continuously looking for more sustainable ways to build, and from now on we will always offer our clients a lower-emission alternative as part of every tender calculation,” Lehtimäki says.

Steel-related emissions account for roughly one-third of Enersense’s total carbon footprint, making the shift towards lower-emission steel a key element of the company’s climate work. Recycled steel typically produces around 40% less carbon dioxide compared to steel manufactured using the traditional iron ore–based process.

The three new substations in Satakunta are scheduled for completion between 2026 and 2027.

CEO Kari Sundbäck

The implementation of the strategy we published in June progressed rapidly during the third quarter. Our strategic focus was reflected in the strengthened order backlog and the improved adjusted EBITDA margin in our core businesses. We sold our Marine and Offshore Unit to Davie at the beginning of the review period, completing the strategic refocusing started in summer 2024 and allowing us to fully concentrate on increasing shareholder value in our core business.

Tomorrow’s society is powered by clean energy and is built on reliable connections. Electricity consumption in our markets grows significantly, which means accelerating investments in the transmission grid. For example, Fingrid predicts that electricity consumption in Finland will double between 2025 and 2035. Finland’s well-functioning energy market attracts investments in our core businesses’ strong areas of expertise.

Our updated strategy responds to the market change and provides a clear direction for our business. Our strategic goal is to be a trusted lifecycle partner for our customers operating in energy transmission and production, the industrial energy transition, and telecommunications, as well as in growing customer segments such as data centres. We aim for profitable growth in Finland, the Baltics and selectively elsewhere in the Nordics. The foundation of Enersense’s business lies in efficiently and transparently executed projects and services. In addition, we optimise the lifecycle performance of our customers’ networks, systems and production facilities. Our lifecycle offering covers design, construction, operation and maintenance, as well as upgrades and modernisations.

The order backlog of our core businesses continued to grow for the second consecutive period, rising to EUR 379 (335) million. We are developing our lifecycle offering in close cooperation with our customers. Third-quarter revenue for the core businesses declined by 11% from the comparison period due to a smaller project portfolio and large projects carried out in the Baltics during the comparison period.

The relative profitability of the core businesses has continued to improve throughout the beginning of the year. Adjusted EBITDA for the core businesses improved to EUR 9.2 (8.7) million, and the adjusted EBITDA margin strengthened to EUR 11.2 (9.6) per cent. Strengthening profitability and our financial base are elementary for to advancing the development outlined in our strategy.

Journey towards lifecycle partnership progressing

We continued our Value Uplift programme, aimed at supporting profitable growth, and made progress in assessing fixed costs and resources. We renewed our operating model to support the implementation of the strategy and to reinforce our ability to respond to future needs with the right kind of expertise. As a result of the renewal, our responsibility areas are clearer and our performance is better. The operating model became effective after the review period on 1 October 2025.

The measures implemented in the Value Uplift programme by the end of September to improve procurement performance will contribute EUR 4 million improvement to the annual EBIT/EBITDA run-rate. During the rest of the year, we will continue to develop our procurement performance and aim for an annual EBIT/EBITDA run-rate improvement of EUR 5 million by the end of the year.

We have set ambitious climate targets that will enable us to improve our customers’ sustainability. After the review period, in October, we submitted our climate targets for validation in accordance with the Science Based Targets Initiative and drew up a climate roadmap. At the same time, we conducted practical climate actions; we started in Satakunta on a substation built from recycled steel, and by the end of the year, we will have replaced a third of our service vehicles in Finland with electric ones.

During the year, we have built a solid foundation for Enersense’s profitable growth and increased shareholder value. The commitment of our employees and valuable feedback from our customers help us achieve our goal of being a trusted lifecycle partner for our Power, Energy Transition and Connectivity customers.

Significant events after the review period

On 7 October 2025, Enersense announced that Fingrid selected Enersense to construct 100 kilometres of new 400-kilovolt transmission line in Central Finland.

2025 Q3 Business Review

Enersense will deliver Fingrid’s Nokia substation as a turnkey project

Enersense International Plc | Investor News | October 30, 2025 at 11:00:00 EET

Enersense has won the Finnish transmission system operator Fingrid’s tender for the delivery of a new substation in Nokia. The contract covers the entire project from design to construction and commissioning.

The tender concerns Fingrid’s 400/110 kilovolt substation. A substation is an important hub in the electricity grid, where electricity is converted and directed forward at the correct voltage.

Valued at approximately EUR 27 million, it is the largest individual substation project in Enersense’s history.

The new substation will improve electricity transmission reliability and increase the capacity of the main grid. The substation is part of Fingrid’s Kristiinankaupunki–Nokia transmission project and will particularly strengthen the connection capacity in the Pirkanmaa region.

According to Juha Silvola, Enersense’s EVP, Power Business Unit, the Nokia substation is an important critical energy infrastructure project for Enersense.

“We are grateful that our strong cooperation with Fingrid continues. We have received excellent quality ratings from our previous similar projects, and we will carry out this project with the same commitment. The project supports the goals of our new lifecycle strategy, strengthens our order backlog, and reinforces our market position in substation operations,” says Silvola.

The project will employ Enersense until 2028. The contract will be recorded in the Power Business Unit’s order backlog for the fourth quarter of 2025. The decision will become legally binding after the expiry of the appeal period under the Finnish Public Procurement Act.

Enersense builds a new 110 kV underground cable line to strengthen Tartu’s electricity network

Enersense International Plc | Investor News | October 24, 2025 at 14:30:00 EEST

Enersense and Estonia’s transmission system operator Elering have signed a contract for the construction of a new 110-kilovolt high-voltage underground cable line between the Tartu and Tööstuse substations in the southeast of Estonia.

This project marks the next stage in Elering’s long-term program “Urban Underground Powerlines”, which aims to replace overhead lines in cities with underground cables to make the urban landscape more attractive and improve the reliability of electricity supply.

As part of the project, Enersense will build a new underground cable line to replace approximately 6.5 kilometres of existing 110 kV overhead lines and dismantle the old structures upon completion.

As a result, around 32 hectares of land will be freed from existing construction restrictions, and Tartu will benefit from a more modern, reliable and visually cleaner electricity network.

“We thank our client for their trust. It is an honour for us to take part in building a reliable and future-proof power grid in Estonia,” says Ott Sillukse, Head of High Voltage at Enersense in Estonia.

The work is scheduled for completion in the second half of 2027. The new underground cable will mostly follow the existing overhead line corridor, though in some sections a new route has been chosen to ensure an optimal and safe layout. Most of the cable will be installed using directional drilling technology, which allows the work to be carried out underground without extensive excavation.

“Our team works every day to make Estonia’s electrical infrastructure smarter, safer, and more sustainable. This project is an excellent example of cooperation that creates value for both the community and the entire energy system,” says Enersense’s Senior Project Manager Agur Kollom.

The value of the project is approximately EUR 5 million, and it will be recorded in Enersense’s Power business unit’s order backlog for the fourth quarter.

The picture shows the cables running along the side of the tower, which connect the underground cables to the main mast.

Enersense’s share buy-back program commenced in August has been completed

Enersense is building 100 kilometres of new main grid in Central Finland

Enersense has won Fingrid’s tender concerning the construction of a new 400-kilovolt transmission line in Central Finland. In total, 100 kilometres of new transmission line will be built. Enersense has also designed the transmission line that will now be constructed.

The new line will run between Alajärvi and Petäjävesi, from South Ostrobothnia to Central Finland.

“The main grid is an important part of Finland’s critical infrastructure. It is an honour for us to ensure the transmission line is built with high quality and safety. The agreement we have now signed strengthens our position as a lifecycle partner for main grid projects, as we have also designed the line to be built,” says Juha Silvola, EVP, Enersense’s Power business unit.

The project includes dismantling the old line and constructing a new one. New pylons and foundations will also be built, and the new transmission line will be connected to four different substations.

The value of the project is approximately EUR 27 million, and it will be recorded in Enersense’s Power business unit’s order backlog for the third quarter. The decision becomes legally binding after the appeal period specified in the Finnish procurement law has ended.

In August 2025, employees at Helen’s Vuosaari power plant gained a new colleague, a robot dog. Robot dog is an example of a digital solution that adds value for customers and enhances employee safety. Reportedly, this is the second power plant in Finland to employ a robot dog.

The robot primarily performs various measurements. It measures vibrations, temperature, and the condition of bearings under conveyor belts more accurately than humans. The dog is equipped with cameras, allowing staff to inspect different areas remotely via computer. It is agile and compact, enabling it to work in tight spaces.

Thanks to the robot’s continuous monitoring, deviations are detected immediately, allowing corrective actions to be taken faster. Likewise, maintenance intervals can be extended when actions are carried out only when truly necessary.

Robot dog makes work safer and more engaging

The robot dog improves both safety and job satisfaction. While measurements are essential, they are monotonous tasks for humans. The areas where the robot operates are often dusty and confined. For instance, air containing sawdust can be harmful to humans. Additionally, the robot dog has a gas detection sensor that alerts staff if carbon monoxide levels become hazardous.

“There are areas in the plant where humans must constantly monitor air quality meters. These are not particularly pleasant places to work, so from a wellbeing perspective, it’s great to have a four-legged assistant,” says Enersense’s development engineer Patrick Niemi.

Initially, a human works closely with the robot dog, but the aim is to train it to operate independently. If needed, a person can control the robot via a tablet. At Enersense, a designated “robot master” trains the dog.

“There has been a lot of interest in becoming a robot master. Many employees are clearly excited about the new colleague, and people from both Enersense and Helen want to come and see it,” Niemi explains.

“In our new strategy, we have committed to providing customers with efficiency and transparency through digital solutions. This also makes us more competitive as a company.”
