II.ANNUAL MANAGEMENT REPORT OF THE BOARD OF DIRECTORS OF “TERNA ENERGY SOCIETE ANONYME INDUSTRIAL COMMERCIAL AND TECHNICAL COMPANY” ON CONSOLIDATED AND SEPARATE FINANCIAL STATEMENTS FOR FINANCIAL YEAR 2024

Dear Shareholders,

According to the provisions of Law 4548/2018 as well as Law 3556/2007 Article 4 par. 2(c), 6,7 & 8 and the decisions issued by the Hellenic Capital Market Commission under No. 8/754/14.4.2016 Article 2 and the Company’s Articles of Association, we are hereby presenting the annual management report of the Board of Directors for the financial year from 01/01/2024 to 31/12/2024.

This report includes the financial and non-financial report of TERNA ENERGY Group for the financial year 2024 and describes the most significant events that occurred before and after the reporting date of the financial statements. Furthermore, it provides a description of the main risks and uncertainties that the Group may face in 2025 and lists the significant transactions entered between the Company and its related parties.

A) Financial Highlights and Performance for the financial year 2024

The Greek economy maintained its positive growth rate for the year 2024, achieving higher levels than the corresponding average of other European countries. This achievement reflects its resilience in a period when the global economy is highly fluctuating and facing significant challenges, particularly at the geopolitical level (ongoing tensions in Ukraine and the Middle East, the political cycles in the US). Over the last year there has been a general normalisation of economic circumstances with inflation declining, energy prices stabilise and the gradual reversal of restrictive monetary policy leading to a positive outlook for the European economy.

For Greece, GDP for 2024 increased by 2.3% year-on-year, driven mainly by an increase in private consumption (as a result of rising household income and falling unemployment) and investment. The momentum in tourism continued, leading to an increase in exports and services, but rising domestic demand led to higher imports with the balance remaining negative.

Inflation for 2024 declined compared to 2023 with the 12-month annual increase of 2.7%, compared to 3.5% for the 12-month period of 2023, following a deceleration in industrial goods and food prices while services inflation remained higher.

In the budgetary sector, the over-performance against targets continued as a result of a reduction in tax evasion, increased economic activity and profitability, but and expenditure control. As a result, the primary surplus is expected at 2,5% of GDP for 2024 (compared to 2,1% for 2023).

Finally, it is also worth noting that following the country's upgrade to investment grade in the second half of 2023 (by R&I, Scope, DBRS, S&P and Fitch), in 2024 Scope Ratings upgraded the Greek economy further to "BBB" while DBRS, S&P and Moody's revised the outlook for the economy to positive. Against this backdrop, the spread of the Greek 10-year bond over the German bond narrowed to 83 basis points in December 2024 (the lowest in 15 years) with the yield standing at 2.97%.

The Greek economy is expected to remain positive in the years to come and to continue to move at a higher rhythm than the Eurozone. For 2025-26, GDP is expected to strengthen by 2.0%-2.5% according to the converging forecasts of the Bank of Greece, the European Commission and the Greek government, compared to a rate of 1.3%-1.6% for the Eurozone. This is expected to be helped by a strong labour market supporting consumption along with continued support from tourism, industry and construction. A positive impact is also expected to come from increasing liquidity from both the private and public sectors, which will be strongly supported by the absorption of European funds. It is noteworthy that total investment spending by the public sector is expected to reach 6,0% of GDP for 2025-26.

Nevertheless, exogenous factors such as the potential strengthening of protectionism and political turbulence in major European economies and key trading partners of Greece are immediate and visible risks to this process.

With regard to the Greek energy market, the normalisation of conditions has generally continued despite some periods of volatility. Thus, in the second half of the year, the return of geopolitical risk that raised again energy sufficiency issues and regional issues in energy markets increased volatility, driving prices to a higher level. The average price in the Greek wholesale electricity market was set at €100.7/MWh for 2024, a decrease of 15.6%. It is also remarkable that for the first time in its history Greece recorded net exports of electricity (even if at a marginal level). Electricity demand in the interconnected system in the country showed an increase of 4.7% for 2024. Renewable energy production increased by 17.8% in 2024 and combined with hydropower plants covered 55% of total demand (compared to 51.3% for 2023). Production from natural gas plants also increased by 38%, covering 39% of demand, while lignite generation continued to decline, covering 6.2% of demand.

In relation to wind power, according to ELETAEN's data, installed capacity at the end of 2024 amounted to 5,355MW, up 126MW compared to 2023 (+2.4%), with the decrease in growth rate due on the one hand to the high base (2023 was the second best year historically in terms of additions) but also an important factor remains the delay due to bureaucratic licensing obstacles. TERNA ENERGY remains the largest producer in the market with a 19.3% share. At the end of 2024, over 1.1 GW of new wind farms were under construction or contracted, the vast majority of which are expected to be connected to the grid within the next 18 months. To these should be added another 300 MW or so, which have been competitively shortlisted, have submitted performance guarantees but do not belong to any of the above categories. As a result, the total wind capacity will exceed 6.5 GW within the next two years.

TERNA ENERGY GROUP

On November 28, 2024, Abu Dhabi Future Energy Company PJSC - Masdar ("Masdar") announced the successful completion of the acquisition of 70% of the shares of TERNA ENERGY S.A. from GEK TERNA S.A. and other shareholders. This transaction is the largest energy transaction in the history of the Athens Exchange and one of the largest in the renewable energy sector in the European Union.

Masdar (Abu Dhabi Future Energy Company) is one of the fastest growing renewable energy companies in the world. As a pioneer in clean energy, Masdar promotes the development and implementation of solar, wind, geothermal, battery storage and green hydrogen technologies, helping to accelerate the energy transition and achieve global zero-carbon targets. Since its founding in 2006, Masdar has developed and invested in projects in more than 40 countries, with a total capacity of more than 31.5 gigawatts (GW), providing affordable clean energy to those who need it most and supporting a sustainable future. Jointly owned by Abu Dhabi National Energy Company PJSC (TAQA), Abu Dhabi National Oil Company (ADNOC) and Mubadala Investment Company, Masdar is targeting a 100GW renewable energy capacity portfolio by 2030 and aspires to become a leading green hydrogen producer in the same year.

The acquisition of TERNA ENERGY Group reflects Masdar's confidence in the company's impressive growth potential, targeting 6GW by 2029, playing an important role in strengthening Masdar's portfolio across Europe as it targets 100GW globally by 2030 to support the energy transition.

Remaining committed to its strategy, TERNA ENERGY Group continues the implementation of its investment plan with the construction of mature projects and the strengthening of its portfolio with the further maturation of projects from the existing portfolio and the addition of new projects in various stages. In this

context, through the newly acquired companies ENERGY SUN II, ENERGY SUN III & BIO PI DI SOLAR EOOD, the construction of solar energy production units from photovoltaic power plants in Greece and Bulgaria with a capacity of 168,5 MW has started.

Moreover, for the long-duration storage project with pumped storage technology in the area of Amphilochia (680 MW), which had already started by the end of 2022, construction works are ongoing and expected to be completed within approximately four years.

As of 31/12/2024, TERNA ENERGY Group owns almost 2.500 MW of RES power plants, in operation, under construction or ready for construction in Greece, Central and Eastern Europe. Including projects in various stages of maturity, the Group's portfolio is approaching 12 GW.

Specifically, the Group's total installed capacity in Greece and abroad amounts to 1.224,3 MW.

TERNA ENERGY Group has transferred the biomass power plants of the waste management facilities' (See Notes 5 and 7).

In the context of the agreement for the Sale and Purchase of the Shares of TERNA ENERGY SA by MASDAR HELLAS SA, TERNA ENERGY Group has transferred to GEK TERNA Group the activities of construction of public works, concessions related to the operation of infrastructure and other projects of public interest as well as all research activities in the USA. Therefore, the results of these activities are presented as results from discontinued operations as defined in IFRS 5 'Non-current assets held for sale and discontinued operations'.

In 2024 the Group consolidated sales from continuing operations amounts to € 347,1 million compared to € 252,2 mill. in 2023, with an increase of 37,6%. The Group's operating earnings before interest, taxes, depreciation, and amortization (EBITDA) from continuing operations amounted to € 210,3 million compared to € 172,8 million in the previous year, increased by 21,7%. Excluding the cost of the free share distribution plan, the Group's operating earnings before interest, taxes, depreciation and amortization (EBITDA) from continuing operations for the year 2024 amount to € 212,6 million, with the respective amount of the previous year was € 173,4million, increased by 22.6%.

Profits before tax from continuing operations to € 93,8 million, increased by 26,2% compared to € 74,3 million in 2023. Net operating profit from continuing operations attributed to the shareholders of the parent company amounted to € 70,4 million, increased by 24,3% compared to the previous year (2023: € 56,7 million).

The increase in sales, operating earnings before interest, taxes, depreciation and amortization (EBITDA) and earnings before and after taxes was mainly driven by the commissioning of the new Wind Farms in the area of Kafireas in Evia and the return to normal levels of wind power, which during the first half of 2023 was extremely low.

The Group's turnover from discontinued operations amounted to € 60,5million compared to € 75,6million in 2023, decrease of 20,0%mainly due to the reduction in the construction operations. The Group's operating loss before interest, tax, depreciation and amortisation (EBITDA) from discontinued operations amounted to a loss of € (17,8) million compared to a profit of € 5,0 million in the previous year. Losses before tax from discontinued operations amounted to € (33,8) million, compared to a profit of € 6,8million in the

corresponding period of 2023. Net loss for the year from discontinued operations attributable to owners of the parent company amounted to € (37,1) million, compared with a profit of € 3,0 million in the corresponding same period of the previous year. The negative performance was mainly due to the construction activity which during the year 2024 was loss-making mainly in the construction of the waste management plants of the Peloponnese Region.

Net profit from continuing and discontinued operations excluding the plan's expense from the free share distribution and results from financial instruments at fair value amounted to € 35,1million.

Total comprehensive income (from continuing and discontinued operations) amounted to € 34,0 million compared to a profit of € 62,1 million in the same period of the last year. For the year 2024, the total profit attributable to Owners of the Parent amounted to € 35,7 million, while the profit attributable to Non-Controlling Interests amounted to € 0,7 million.

The amount of research and development expenses incurred by the Group during 2024 amounted to € 6.187thousand compared to € 5.371thousand in the corresponding period of the previous year. These expenses are mainly related to the development of new renewable energy production plants and the capacity to conclude new contracts through public tenders.

The Group's operating cash flow from continuing operations for the year amounted to € 139,1 million, compared to € 147,2 million in 2023. The increase is mainly attributable to the liquidation of the increased results realized in the year 2023 which is expected to be reversed during the 2024 financial year.

On 31/12/2024, TERNA ENERGY Group investments amounted to € 102,0 million. The Group’s on-going investing activities generate the conditions for stabilization of increased flows of revenue and profitability on a long-term basis.

The Group's financial position remains satisfactory, as cash and cash equivalents and restricted cash amounted to € 311,9 million, while the loan liabilities amounted to € 1.107,5 million. The net debt position (debt liabilities minus cash and cash equivalents minus restricted deposits related to debt liabilities) as of 31/12/2024 stands at € 795,6 million compared to € 844,6 million in the previous financial year.

E. Risks and uncertainties

The Group’s activities expose it to various financial risks such as market risk (including foreign exchange risk, interest rate risk and price volatility risk), credit risk and liquidity risk. The Group, in order to deal with the financial risks and to limit their negative impact on its financial results, monitors the fluctuations of the variables that affect cost and sales and uses the appropriate products, as the case may be.

The main risks and uncertainties related to the Group's operations are as follows:

i.Credit risk

The Group examines its receivables on an on-going basis and incorporates the arising data in its credit control. The majority of the energy segment receivables relates to the broader domestic (including ENEX, DAPEEP and DEDDIE) and foreign Public Sector. Given the nature of its operations, the Group traditionally is not exposed to significant credit risk from trade receivables. In the past, there have been delays in collections from DAPEEP, which have been significantly reduced with the implementation of Law 4254 /14 as well as the extraordinary levy imposed for the fiscal year 2020 to address the side effects of the coronavirus pandemic, on electricity producers from Renewable Energy Sources (RES) power plants, which have been brought into normal or trial operation by 31 December 2015 (Government Gazette 245/09.12.2020). In other transactions with individuals, the Group operates with a view to limiting credit risk and securing its receivables. The credit risk in respect of cash and cash equivalent and other receivables is low, since the parties to the transaction are banks of high-quality capital structure, the State or the entities of the broader Public Sector or strong business groups.

Lastly, Group Management estimates that all the financial assets, for which the necessary impairments have been performed, are of high credit quality.

ii.Foreign exchange risk

Besides Greece, the Group operates in Eastern Europe and, therefore, it may be exposed to foreign exchange risk, potentially arising from the exchange rate of Euro against other currencies. This type of risk may arise only from trade transactions in foreign currency, from financial investments in foreign currency, as well as from net investments in foreign entities. To limit this risk, the Group uses the cash surpluses generated in local currency. During the operational phase, all related costs and revenues are made in local currency, thus excluding any possibility of generating currency exchange differences.To mitigate this risk, the Group's financial management department systematically monitors exchange rate fluctuations and ensures that they do not adversely affect its cash flow.

Regarding the Company’s transactions with foreign entities, such transactions primarily take place with European Groups, where Euro is the settlement currency and, therefore, such transactions are not exposed to foreign exchange risk.

iii.Interest rate risk

The Group’s policy is to minimize its exposure to cash flow interest rate risk with regards to its long-term financing. In this context, long-term loans received by the Group either bear a fixed interest rate or are hedged for almost the entire duration. Thus, 16,55% of the Group's long-term borrowings refer to fixed rate loans59,67% refer to floating rate loans hedged through derivatives whereby future fixed rate payments are exchanged for floating rate receipts, and 23,78% to floating rate loans based on euribor or wibor.

The Group’s total short-term bank loans are in Euro under floating interest rates linked to euribor. Short‐term loans are primarily received as bridge financing during the phase of implementation and construction of the

TERNA ENERGY GROUP

Annual Financial Report for the Year 2024

(Amounts in thousands of Euros unless mentioned otherwise)

11

Group’s investments (Wind parks). These loans are expected to be repaid within one year, while new short‐term loans are expected to be received to finance the construction of new wind parks.

Therefore, the Group is exposed to interest rate risk arising from short-term debt and the part of long‐term debt that is under floating interest rates. The Group is not exposed to other interest rate risks.

Sensitivity analysis of interest rate risk

In the table below is presented the sensitivity of earnings for the year versus the Group's short-term borrowing and deposits, at a change in the variable part of the interest rate of +20% - 20% (2023: +/- 20% correspondingly).

Changes in interest rates are estimated to fluctuate on a reasonable basis in relation to the recent market conditions.

	2024		2023
Amounts in thousand €	20%	(20)%	20%	(20)%
Results for the year after tax – Group	(3.349)	3.349	(2.263)	2.263
Results for the year after tax – Company	(280)	280	(301)	301

The Group is not exposed to other interest rate risks.

iv.Market risk analysis

The Group is not exposed to market risk for its financial assets, with the exception of the portfolio of listed securities. The Group has not taken specific hedging measures for this risk as any impact is not expected to be significant.

v.Liquidity risk analysis

The Group’s liquidity is considered satisfactory, as apart from the effective cash and cash equivalents, currently operating wind farms generate satisfactory cash flows on an on-going basis. In the year 2024 net cash flows from continuing operating activities amounted to € 139 million versus € 147 million in 2023. The Group manages its liquidity needs by applying cautious cash flow planning, by carefully monitoring the balance of long‐term financial liabilities as well as by systematically managing the payments which take place daily. The liquidity needs are monitored in different time zones, on a daily and weekly basis, as well as based on a moving 30‐day period. The liquidity needs for the next 6 months, and the next year are defined monthly.

The Company maintains cash and cash equivalents in banks, to cover its liquidity needs for periods up to 30 days. The capital for mid‐term liquidity needs is released from the Company’s term deposits.

vi.Other risks and uncertainties

(a) Climate Change Risk and Fluctuations in wind and hydrological data

The Group's core business is closely linked to climate conditions and in this context, management closely monitors developments and assesses the potential impact that climate change may have on the smooth operation of the facilities. From now on, calculation models should incorporate new factors allowing for the occurrence of potential events of force majeure, to examine in greater depth the viability of each projected investment.

Regarding its activity in the energy sector, the Group remains exposed to short-term fluctuations in wind and hydrological data, without affecting the long-term profitability of its projects, as the implementation of its investments is preceded by extensive studies on the long-term behaviour of these factors.

(b) Political evolutions in the Group's area of operation

TERNA ENERGY GROUP

Annual Financial Report for the Year 2024

(Amounts in thousands of Euros unless mentioned otherwise)

12

The military conflicts in the wider region of the Group's operations such as Ukraine and Middle East continue, and TERNA ENERGY Group continues to closely monitor the developments which have not had and are not expected to have a direct impact on the Group's figures and performance. As the majority of the A/Ps have a fixed sales price, the significant costs are depreciation of equipment and borrowing costs, which refer to fixed rate loans, the impact of which continues to be insignificant, and this is not expected to change in the foreseeable future.

Finally, due to the dynamic nature of these events, new risks may arise. Considering the current uncertainty about the wider economic climate, the Group's management is trying to assess any indirect consequences on the Group in a timely manner.

F. Alternative Performance Measurement Indicators (“APMI”)

In the context of applying the Guidelines “Alternative Performance Measures” of the European Securities and Markets Authority (ESMA/2015/1415el) which are applied from 3rd of July 2016 in the Alternative Performance Measures Indicators (APMI).

The Group utilizes Alternative Performance Measurement Indicators ("APMI") in its financial, operational and strategic planning decisions, as well as in evaluating and publishing its performance. These APMI serves to better understanding the Group’s financial and operating results as well as its financial position.

Alternative indicators should always be considered in conjunction with the financial results prepared in accordance with IFRSs and in no case should they replace them. The following indicators are used when describing the Group's performance by sector:

EBIΤ (Earnings before Interest and Taxes): It is a ratio by which the Company's Management assesses its operating performance.

As the largest producer and investor in clean energy across the region, the Group has a total project capacity—encompassing operational, under-construction, and ready-to-build projects—totaling 2.5GW in 2024. Including projects in various stages of maturity, the Group's portfolio exceeds 11 GW.

Overall Business Strategy

The Group's business activity is characterized by a solid financial structure, deep specialization and expertise, full implementation of quality assurance procedures, and extensive understanding of the international financial and business landscape. Its business model is based both on responsible planning and effective implementation of every project it undertakes. Moreover, the Group ensures sufficient capital and liquidity throughout each project phase by adhering to successful and responsible business practices, while ensuring its business continuity and sustainable growth.

2.The Group’s approach to Sustainable Development

ATHEX Metric C-G4: Sustainability Policy

The Group’s unwavering commitment to Sustainable Development principles serves as a cornerstone for its business operations. Central to this commitment is the Group's Sustainable Development Policy which prioritizes stakeholders and emphasizes systematic assessment of the material impacts of its activities on the economy, society, and the environment.

The Sustainable Development Policy aims to amplify the positive contribution of the Group's activities while mitigating the negative effects. By implementing a range of best practices, targeted initiatives, and sustainable partnerships, TERNA ENERGY Group works towards its ultimate goal of creating long-term value for both stakeholders and society as a whole.

The Group's business strategy is intricately aligned with the material topics and needs identified by its stakeholder groups, guiding the implementation of targeted actions for environmental and societal impact in accordance with the United Nations' 17 Sustainable Development Goals (SDGs). As part of the Group’s Sustainable Development Policy, corporate responsibility is aligned with the ESG (Environmental-Social-Governance) criteria and principles applied across four (4) activity axes:

▪Environmental Protection

▪Human Value Promotion

▪Strengthening our Social Footprint

▪Shaping a Responsible Market

These focus areas form the basis for the Group’s sustainability goals and targets, which are meticulously defined and assessed annually to ensure their continued relevance and to make adjustments as necessary. To support these objectives, the Group develops and implements robust management systems, policies, and procedures, utilizing Key Performance Indicators (KPIs) and metrics. Additionally, efficient action plans and programs are adopted to effectively monitor and achieve sustainable development goals and targets.

To enhance transparency and facilitate stakeholder engagement, the Group's performance on ESG topics is published in the annual Sustainable Development Report and the current Statement. In 2024, during the development of its annual sustainability report, TERNA ENERGY conducted a 'double materiality' assessment to identify the sustainability issues that are most relevant to its business and stakeholders. This effort aligns with the Group's commitment to transparency, accountability, and sustainable business practices by identifying its material impacts, risks, and opportunities related to sustainability topics.

The double materiality approach helps the organization meet regulatory requirements while boosting transparency, stakeholder engagement, and sustainable business practices. It involves assessing how business operations impact the economy, society, and environment, as well as how sustainability issues affect the company's financial performance and strategies.

More specifically, TERNA ENERGY Group has adopted a 4-step approach for performing its Double Materiality Assessment in line with European Sustainability Reporting Standards (ESRS) provisions. It is a structured process designed to evaluate the material impacts and dependencies of their business activities on environmental, social, and governance (ESG) factors. While the specific details of each phase may vary, the general approach typically involves the following steps:

▪Understanding: This phase involves identifying relevant ESG issues that could impact the organization or be impacted by its operations. This includes a deep understanding of its operation, business relationships and value chain, as well as gathering input from a variety of stakeholders such as employees, investors, customers, suppliers, and local communities.

18

▪Identification: This phase involves identifying relevant impacts, risks and opportunities associated with the potentially significant ESG issues that have been identified during the previous phase.

▪Prioritization: In this step, the identified issues are evaluated and prioritized based on their score that reflects their significance to the company and its stakeholders. This is accomplished through stakeholder engagement both for impact and financial materiality assessments.

▪Determination: The material IROs arising from the assessment phased result in a list of material issues. These material ESG topics are reviewed and validated by the organization’s leadership and key stakeholders to ensure alignment with the company’s strategic objectives and stakeholder expectations.

3.Corporate Governance and the Group's Basic Operating Principles

Corporate Governance comprises a framework of established rules and business practices that the Group applies to ensure business continuity and the creation of long-term value for its shareholders. This commitment to responsible governance and ethical business conduct is encapsulated in the Corporate Governance Code, set forth by the Management.

The Board of Directors (BoD) serves as the Group’s highest management body. Its members are elected by the General Meeting of Shareholders with its primary mission being the establishment of the Group’s core guidelines and the development of its business strategy. Additionally, the BoD is entrusted with overseeing procedures that ensure effective business operation, implementation of the Group’s core principles and the expression of the administrative philosophy of the Group. Moreover, it is also responsible for decision-making across all corporate matters, except those reserved for the General Assembly.

The BoD is dedicated to safeguarding and advancing the long-term interests of shareholders by implementing practices and methods that build the company’s credibility within the financial and business community and the broader social environment, while fostering mutual respect among all stakeholders. To enhance its effectiveness and establish a responsible business model, the BoD is supported by specialized Committees that play an advisory role with significant influence over decision-making:

•Audit Committee

•Nominations Committee

•Remuneration Committee

•Strategic Planning Committee

•Investment Committee

•ESG Committee

Aiming to enhance oversight of the Group’s Sustainable Development issues, the ESG committee convenes at least 4 times a year or whenever required, discussing the Group's ESG performance and goals.

The Group is steadfast in its commitment to reducing its carbon footprint, implementing strategic initiatives that align with global sustainability goals and demonstrate a profound responsibility towards climate action. To achieve a GHG emissions reduction by 2025, several key actions have been implemented.

▪Implementation of a strategy to reduce energy consumption and greenhouse gas emissions in its buildings and facilities.

▪Use of 100% green electricity in all Group's facilities in Greece and abroad from 2021 onwards, and therefore zero indirect greenhouse gas emissions (Scope 2 market-based) related to all Group’s facilities.

▪Continuous assessment of risks and opportunities related to climate change, carried out within our Environmental Management System, and alignment with TCFD recommendations.

▪Acceleration of investment plans in the field of energy storage, with the aim of contributing decisively to maximizing the penetration of RES and to the achievement of the Greek national energy and climate goals.

▪4.2.2Protection and conservation of Biodiversity

▪Μetric ATHEX A-E5: Biodiversity sensitive areas

Biodiversity conservation is a key focus area of TERNA ENERGY Group's approach to environmental issues, reflecting its commitment to ensure the resilience of ecosystems that support the planet's health and sustainability. In managing the impacts on biodiversity resulting from the Group's activities, TERNA ENERGY Group employs best practices and advanced technologies to minimize negative effects and create positive outcomes for natural ecosystems in or near its operational areas. The Group implements the following measures:

▪Thorough site investigations during the planning phase of projects and necessary infrastructure to identify special requirements or restrictions due to national and European regulations (such as the Habitat Directive 92/43/EEC) and to determine if projects are located within protected areas like the Natura 2000 network or other regions with land use limitations.

▪Preparation of Environmental Impact Assessments (EIA) and other specific studies in compliance with the relevant international (when required) and national legal frameworks.

▪Implementation of a certified Environmental Management System (EMS) and provision of specialized training.

The EMS has been developed and communicated to all stakeholders in the supply chain, including employees, partners, suppliers, and subcontractors. Training sessions are organized for the Group's employees and subcontractors.

▪Development of long-term monitoring programs to assess the interaction between wildlife (including birds) and the Group's facilities, in accordance with Environmental Terms Approval Decisions (ETADs) and beyond.

▪Installation of avifauna protection systems at wind farms, as stipulated by approved Environmental Terms, utilizing automated bird identification software and high-definition cameras. Since 2021, bird protection systems have been operational in wind farms located in Crete, Evros and Evia.

During the construction of the Amfilochia pumped-storage project, audits are carried out during vegetation clearing and excavation of the surface soil, as part of environmental monitoring and compliance with environmental permits. Additionally, the area within a radius of at least 100 meters around the intervention point is investigated to identify wildlife species (mammals, birds, reptiles, amphibians, fish) that may be at risk from the activity, so that, if necessary, they can be relocated to a safer location. Furthermore, an ornithologist is employed to conduct monthly field research and prepare relevant reports.

4.2.3Responsible waste management

Μetric ATHEX A-E3: Waste Management

TERNA ENERGY Group is committed to responsible waste management practices across its operations and those of its suppliers and partners, both domestically and internationally. Misaligning with these practices, can lead to adverse effects at multiple levels: locally, it can result in environmental contamination and a decline in residents' quality of life; nationally, it can contribute to the degradation of natural ecosystems and exacerbate solid and liquid waste management challenges. Additionally, poor waste management can disrupt the Group's operations, potentially leading to sanctions or operational disruptions due to uncontrolled waste production or disposal methods.

To mitigate these risks, the Group actively invests in Circular Economy principles, emphasizing reuse and recycling. It rigorously adheres to the standards set by its certified environmental management system, conducting both internal and external audits to identify areas for improvement. This proactive approach enables the Group to implement preventive and corrective measures effectively, ensuring sustainable waste management practices are maintained.

4.3Non-Financial performance indicators

To ensure environmental compliance, in 2024, more than 60 internal and external audits were carried out at all the Group's facilities.

5.Sustainable Supply Chain

To maximize its positive impact, the Group evaluates the environmental, social, and economic implications of its business activities across the entire supply chain. In response to emerging supply chain challenges, the Group continually revises its management criteria, incorporating new engagement terms with suppliers and prioritizing domestic partnerships. Each year, the Group strives to deepen its collaboration with local suppliers, fostering trust-based relationships that invigorate local communities and enhance the Group's socio-economic footprint.

5.1 Due diligence and other policies.

TERNA ENERGY Group acknowledges the critical role of promoting core principles and values related to corporate culture and business ethics within the supply chain. This dissemination is seen as a vital component of conducting business responsibly. In this context, the Group has in place its

Purchasing Policy

that is universally implemented, defining the basic framework of policies, values and commitments that should characterize the professional behavior of all the Group's partners, including its subsidiaries in Greece and abroad. Therefore, an agreed-upon and transparent operational and behavioral framework is established to guide all our partners, subcontractors, and suppliers.

The Procurement Policy acknowledges the potential risks arising from incidents where suppliers breach international standards or laws or fail to align with the Group's established policies and values. It is recognized that supply chain risks could stem from insufficient support for local and domestic suppliers, potentially diminishing their purchasing power and negatively impacting economic growth and prosperity in the regions where the Group operates.

5.1.1Supply Chain Assessment

Μetric ATHEX C-S8: Supplier Assessment

The Group prioritizes responsible supply chain management as a core element of its strategy to generate long-term value through its business operations and foster sustainable relationships with suppliers and partners. To achieve this, the suppliers and partners that the Group collaborates with are carefully selected to align with its Procurement Policy. Moreover, the Group clearly communicates the minimum cooperation requirements aimed at upholding environmental, energy, and social standards as outlined by its policies and procedures.

Key conditions for collaboration with any supplier include full compliance with the regulatory framework concerning Health and Safety, and environmental management, the Code of Conduct and Ethics, the Human Rights Policy, and the Personal Data Protection Policy. These standards are essential for maintaining the proper and secure functioning of the supply chain, while ensuring the safe execution of all operations. Furthermore, the Group emphasizes the use of materials and equipment that are environmentally friendly, energy-efficient, and pose minimal risk to both users and the environment, in addition to being highly suitable and functional.

In light of these priorities, the Group's process for selecting key suppliers and partners is also guided by ESG (Environmental, Social, and Governance) criteria. The evaluation of these partnerships is conducted periodically to ensure they remain highly suitable and aligned with the Group's objectives.

7.Taxonomy Report

7.1Overview

The EU Taxonomy Regulation (EU 2020/852, as amended) is a key element of the European Commission's initiative, as it is part of the broader EU Sustainable Finance agenda aimed at directing investments towards projects and activities that support the EU's environmental objectives. The Taxonomy targets to provide clarity and transparency to investors, helping them make informed decisions and channel funds towards sustainable projects, thereby supporting the EU's goal of achieving climate neutrality by 2050.

The EU Taxonomy (EUT) is a classification system established by the European Union to identify which economic activities are considered environmentally sustainable. Specific provisions have been set forth in the regulation to classify an activity as green, taking into account detailed technical screening criteria, the Do no Significant Harm Principle (DNSH criteria), and minimum social and governance safeguards.

Within the EU Taxonomy, the following six environmental objectives are identified:

CCM	CCA	WTR
Climate change mitigation	Climate change adaptation	Sustainable use and protection of water and marine resources
PPC	CE	BIO
Pollution prevention and control	Transition to a circular economy	Protection and restoration of biodiversity and ecosystems

The climate-related objectives (CCM and CCA) were set out in the Climate Delegated Act3, and have been applied since 2021, while the remaining four objectives came into force in June 2023 under the Environmental Delegated Acts4, and are effective as of 2023 reporting year onwards.

The following section includes the required disclosures for non-financial entities in accordance with the EUT Regulation provisions to disclose the percentage of the eligible economic activities and the extent to which these are aligned through the Key Performance Indicators (KPIs) defined by the EUT Regulation (Turnover, CapEx, OpEx).

Aiming to achieve full alignment with the EUT Regulation, TERNA ENERGY Group assessed both eligibility and alignment of its business activities for FY2024 through a thorough assessment process in line with the requirements of the EUT Climate Delegated Act and Environmental Delegated Acts.

According to this assessment, the Group’s activities substantially contribute to the Climate change mitigation objective. An overview of the EUT assessment outcomes for FY2024 is presented below:

7.2Eligibility Assessment

All economic activities carried out by the Group in FY2024 were reviewed in order to identify eligible activities under the EUT Regulation. An economic activity is considered Taxonomy-eligible if it is described in the respective Delegated Acts (Climate Delegated Act and the Environmental Delegated Acts) supplementing the EUT Regulation, irrespective of whether that economic activity meets any or all of the Technical Screening Criteria (TSC) laid down in the EUT Delegated Acts. Non-eligible economic activities under the EUT are economic activities not included/described in the Delegated Acts of the EUT Regulation.

The below table presents the Group’s Taxonomy-eligible economic activities conducted in FY2024.

All of the Group's electricity generation and storage facilities fall under activities 4.1, 4.3, 4.5, 4.8 and 4.10 of the EUT and are assessed as eligible for substantial contribution to the CCM environmental objective of the EUT Regulation.

Activities 4.1, 4.3, 4.5 and 4.8 encompass projects for electricity generation using solar photovoltaic technology, wind energy, hydropower, and bioenergy, respectively. Additionally, activity 4.10 features the significant Pumped Hydropower Storage System in Amfilochia of 730MW capacity, incorporated into the Group's project portfolio in 2023 and the Amari (Crete) Hybrid project integrating wind power generation with pumped hydropower storage capacity of 72MW. All these activities significantly contribute to reducing GHG emissions through the generation, transmission, storage, distribution, or use of renewable energy sources.

7.3Alignment assessment

The EUT Regulation sets out four conditions that an economic activity must meet to qualify as environmentally sustainable and aligned:

•substantial contribution to one or more of the six environmental objectives set out in Article 9 of the Regulation, in accordance with Articles 10 to 16 of the Regulation – compliance with substantial contribution Technical Screening Criteria (TSC) set for each objective.

•do no significant harm (DNSH) to any of the remaining environmental objectives set out in Article 9 of the Regulation, in accordance with Article 17 of the Regulation – compliance with DNSH TSC set for each objective.

•be carried out in accordance with the minimum (social) safeguards (MSS) outlined in Article 18 of the Regulation.

For each identified eligible activity for FY2024, TERNA ENERGY Group conducted a thorough assessment to evaluate whether the activity and its associated projects/assets can be ultimately deemed as aligned with the EU Taxonomy TSC for Substantial Contribution to CCM and Do No Significant Harm (DNSH) across the remaining 5 environmental objectives of the EUT.

The assessment also evaluated compliance with the Minimum Social Safeguards (MSS) outlined in Article 18 of the EUT Regulation. These safeguards involve implementing procedures to ensure compliance with the OECD Guidelines for Multinational Enterprises and the United Nations Guiding Principles on Business and Human Rights. This includes adhering to the principles and rights specified in the eight core conventions identified by the International Labor Organization's declaration on fundamental principles and rights at work, as well as the International Charter of Human Rights. The Group thoroughly reviewed all applicable requirements and appropriately applies all relevant procedures and policies.

The Group's electricity generation activities using solar photovoltaic technology (4.1), wind energy (4.3), hydropower (4.5), bioenergy (4.8) and electricity storage activities (4.10) are fully aligned with the substantial contribution TSC for CCM. Details of the alignment assessment and respective evidence are presented below.

7.4Substantial Contribution

Assessing EU Taxonomy alignment starts with meeting the Technical Screening Criteria (TSC) outlined in the EUT Regulation regarding substantial contribution to one or more of the environmental objectives. Each economic activity has specific TSCs that must be fulfilled.

All turnover-generating activities of the Group (4.1, 4.3, 4.5 and 4.8) as well as the future operation of the pumped hydropower storage projects (4.10) substantially contribute to climate change mitigation (CCM) since they meet the relevant TSCs, as presented in the following table.

Table 3: Technical screening criteria ensuring substantial contribution to the CCM objective

EUT eligible activity		Substantial Contribution to CCM TSC	Compliance with TSC
4.1	Electricity generation using solar photovoltaic technology	The activity generates electricity using solar PV technology.	√
4.3	Electricity generation from wind power	The activity generates electricity from wind power.	√
4.5	Electricity generation from hydropower	The electricity generation facility is a run-of-river plant and does not have an artificial reservoir.	√
4.8	Electricity generation from bioenergy	The plants have a rated thermal input of < 2MW and use biomass gas fuel from anaerobic digestion of biowaste. A monitoring and emergency plan to minimize any methane leakage is in place and the biogas produced is used directly for electricity generation.	√
4.10	Storage of electricity	The activity is the construction and operation of electricity storage including pumped hydropower storage.	√

Specifically, the Group’s electricity generation activities using solar photovoltaic technology (4.1) and wind power technologies (4.3) include renewable energy projects (PV plants and wind farms with a total installed capacity of approximately 1.2GW) that substantially contribute to climate change mitigation (CCM) by decarbonizing power generation from fossil fuels and increasing the share of renewable energy sources (RES) in the national and EU energy mix.

Activity 4.5, which involves electricity generation facilities that produce electricity from hydropower, is substantially contributing to CCM. The electricity generation facilities are run-of-river plants and do not have an artificial reservoir. More specifically, the activity consists of two small hydroelectric plants (SHPs) on Acheloos River (Sanidi - Dafnozonara SHP) and on Axios River (Eleousa SHP), with a total installed capacity of 17.8MW.

Activity 4.8 includes an electricity generation facility exclusively from biomass which contributes substantially to climate change mitigation. The biogas plant has a total rated thermal input of 1MW and is designed to produce electricity from biogas resulting from anaerobic digestion of organic material. The plant is supplied with a large amount of organic-rich wastewater from dairy cow farming enterprises, supplemented by feed residues (corn fillings), sludge and waste with organic load. The plant’s operation is based on anaerobic digestion of this organic material, which results in the production of biogas used for electricity generation. The plant implements measures to prevent risks related to the operation of the reactor, including leakage of gases such as methane (CH4).

Finally, activity 4.10 consists of the Group’s pumped hydropower storage systems in Amfilochia and Amari-Crete, currently under construction, which will substantially contribute to CCM further enabling RES integration in the national energy mix.

The assessment of CapEx/OpEx associated with these activities (category A, CapEx/OpEx) follows the conclusions made for the purpose of assessing the Group’s turnover. For investments that also meet specific individual criteria under other activities (category C, CapEx/OpEx) we analyze the investments against these specific criteria. To learn more about how we determined the KPIs please refer to chapter “KPIs and accounting policies”.

7.5Do no significant harm (DNSH)

For all Taxonomy-eligible economic activities where substantial contribution to CCM is demonstrated, their alignment with the DNSH Technical Screening Criteria (TSC) outlined for the remaining environmental objectives is further assessed on a project/asset level. It should be noted that these activities and associated assets/projects are all located within the EU.

7.6Climate change adaptation (CCA)

Activities 4.1, 4.3, 4.5, 4.8, 4.10

For all Taxonomy-eligible activities substantially contributing to CCM, a physical climate risk assessment is required pursuant to Annex I, Appendix A of the supplementary Delegated Act (EU 2021/2139 as in force) under the EUT Regulation.

With respect to the activities carried out by TERNA ENERGY Group, the assessment focuses on the sites where the below facilities are installed:

▪Solar PV park facilities (4.1).

▪Wind park facilities (4.3)

▪Small hydropower plant facilities (SHPs) (4.5)

▪Biogas plant facilities (4.8)

▪Pumped hydropower storage facilities ( 4.10).

For each of these activities and associated project sites a preliminary screening of climate-related physical risks was carried out as mapped in Annex I (Appendix A) and the risks found to be relevant were further analyzed through a climate risk assessment (CRA). As the expected lifetime of all relevant activities is longer than ten years, the CRA was carried out considering an optimistic, a moderate and a pessimistic scenario, compared to the current risk. The impact for each IPCC scenario RCP2.6, RCP4.5 and RCP8.5 (Representative Concentration Pathway) was assessed as these represent the optimistic outcome of zero emissions by 2100, the moderate outcome of emissions peaking around 2040 and then decreasing while global average temperature increases between 1 and 2 oC by 2100 and, thirdly, the pessimistic outcome with a global temperature increase of about 4.3˚oC by 2100.

The risk assessment involves calculating the effect (magnitude) of the potential impacts (on a five-level scale) and the probability (on a five-level scale) that these impacts will occur, as follows:

Risk = probability x impact

Where:

(i) probability is the probability of occurrence of the identified climate risk

(ii) impact is the magnitude of a business effect from the climate risk

The adaptive capacity is based on adaptation plans already in place and internally available measures to mitigate the impact of climate risks identified. The result of the CRA is, for each of the identified climate risks in each scenario, a physical risk score that indicates the materiality of each risk.

7.7Sustainable use and protection of water and marine resources (WTR)

Activity 4.1

The supplementary Climate Delegated Act of the EUT Regulation does not provide applicable TSC regarding DNSH to the sustainable use and protection of water and marine resources (WTR objective) for activity 4.1.

TERNA ENERGY GROUP

Annual Financial Report for the Year 2024

(Amounts in thousands of Euros unless mentioned otherwise)

64

Activities 4.3, 4.5, 4.8, 4.10

Applicable DNSH TSC for activity 4.3 refer to offshore wind farm projects. TERNA ENERGY Group currently has no offshore wind projects included in its portfolio in 2024.

Electricity generation facilities under activities 4.5 and 4.8, located in Greece have all been subject to an Environmental Impact Assessment (EIA) and received approval through the issuance of the respective Environmental Permits from competent authorities in line with national environmental legislation in force. The EIA process included the assessment of potential impacts on water bodies based on Directive 2000/60/EC provisions and harmonized national legislation. In some cases, specific measures were enacted to comply with requirements set by the authorities to maintain the good status and ecological flow of affected water bodies.

Regarding activity 4.10, the Amfilochia and Amari pumped hydropower storage projects are connected to river systems and comply with the relevant TSC outlined in Annex I, Appendix B of the Climate Delegated Act. Before construction, an EIA was conducted in line with Article 4 of Directive 2000/60/EC to evaluate potential impacts on water bodies and dependent habitats. This assessment used recent, accurate data and considered River Basin Management Plans and cumulative impacts from other infrastructures. The EIA concluded with the issuance of a Decision of Approval of Environmental Terms (DAET), which specifies measures to maintain the good status of affected water bodies. These measures are monitored through an environmental monitoring program.

Transition to a circular economy (CE)

Activities 4.5, 4.8

The supplementary Climate Delegated Act of the EUT Regulation does not provide applicable TSC regarding DNSH to the transition to a circular economy (CE objective) for activities 4.5 and 4.8.

Activities 4.1, 4.3, 4.10

PV panels and wind turbines used in the Group’s projects under activities 4.1 and 4.3 respectively, along with the related engineering equipment, are sourced from reputable manufacturers who prioritize high durability and recyclability. In selecting the technologies and products installed in the Group’s assets, durability, recyclability, and the ease of dismantling and refurbishing are all aspects carefully evaluated. The photovoltaic mechanical equipment is reusable to the greatest extent feasible and recyclable in accordance with applicable regulations. The large metal parts of wind turbines, such as tower sections and the cast iron frame, are considered to be 98% recyclable. Other major components, including generators, gearboxes, cables, and diversion system parts, have a recyclability rate of 95%. The Group implements waste management plans in the context of its ISO 14001 certified Environmental Management System (EMS) and respective environmental permits in place, further ensuring that upon decommissioning this equipment is recycled and re-used to the maximum extent possible.

Regarding activity 4.10, waste management plans are in place for the pumped hydropower storage projects, as stipulated by the respective environmental permits in force and the Group's ISO 14001 EMS. These plans ensure the prevention of waste generation and maximal reuse or recycling upon decommissioning. Additionally, contractual agreements with licensed third parties are in place and staff training and awareness on waste management and other initiatives.

Pollution prevention and control (PPC)

Activities 4.1, 4.3, 4.5, 4.10

The supplementary Climate Delegated Act of the EUT Regulation does not provide applicable TSC regarding DNSH to pollution prevention and control (PPC objective) for activities 4.1, 4.3, 4.5 and 4.10.

TERNA ENERGY GROUP

Annual Financial Report for the Year 2024

(Amounts in thousands of Euros unless mentioned otherwise)

65

Activity 4.8

Regarding activity 4.8, DNSH TSC for pollution prevention and control require facilities to comply with specific standards set out in EU Directives and regulations. Emissions produced by the Group’s biogas plant are within best available techniques’ (BAT) ranges. Following the anaerobic digestion process, dissolved water is produced with suspended organic solid waste content at a percentage of about 5%. Solid waste is then separated and used as a first quality soil improver and solid fertilizer, while meeting the requirements for fertilizing materials set out in national legislation on fertilizers or soil improvers for agricultural use. According to the latest studies, our biogas plant processes over 100tof biowaste per day. Emissions to air and water are within or lower than the emission levels indicated by best available techniques (BAT). Considering the above, electricity generation from biomass complies with all DNSH TSC for the PPC objective.

Protection and restoration of biodiversity and ecosystems (BIO)

Activities 4.1, 4.3, 4.5, 4.8 and 4.10

The DNSH TSC for the o protection and restoration of biodiversity and ecosystems (BIO objective) require an EIA or screening procedure conducted in accordance with Directive 2011/92/EU and ensuring that all necessary mitigation and compensation measures for environmental protection are implemented. The Group’s facilities within the EU have undergone an EIA, resulting in the issuance of relevant decisions and approvals by competent authorities. These decisions incorporate the required measures to mitigate and compensate for potential environmental impacts.

In addition, regarding activities 4.1 and 4.8, the Group’s facilities are not located within or near biodiversity - sensitive areas or UNESCO sites. Wind farms (4.3), hydroelectric projects (4.5) and pumped hydropower storage projects (4.10) located within or near biodiversity-sensitive areas, were subject to an Appropriate Assessment (AA or Special Ecological Assessment in Greek) as part of the EIA and environmental permitting procedure of the projects). Based on the AA findings, we have implemented all necessary mitigation and/or compensation measures to address potential environmental impacts effectively, while environmental monitoring is conducted on an annual basis as per issued environmental permits in force of these projects.

7.8Minimum Safeguards (MS)

The final step for Taxonomy-alignment assessment involves the evaluation of compliance with the minimum (social) safeguards (MS). The MS include all procedures implemented to ensure that identified Taxonomy-eligible economic activities are carried out in alignment with:

▪The OECD Guidelines for Multinational Enterprises (OECD MNE Guidelines)

▪The UN Guiding Principles on Business and Human Rights (UNGPs), including the principles and rights set out in the eight fundamental conventions identified in the Declaration of the International Labor Organization (ILO) on Fundamental Principles and Rights at Work

▪The International Bill of Human Rights

In the absence of further guidance from the European Commission, the MS assessment is based on the “Final Report on Minimum Safeguards” published by the Platform on Sustainable Finance (PSF) in October 20225.

The scope of the MS covers the following four topics:

▪Human rights (including labor and consumer rights)

▪Corruption and bribery

▪Taxation

▪Fair competition

TERNA ENERGY GROUP

Annual Financial Report for the Year 2024

(Amounts in thousands of Euros unless mentioned otherwise)

66

A two-dimensional assessment approach is followed to assess compliance with MS. On the one hand, assessing whether adequate processes have been implemented to prevent negative impacts (procedural dimension). On the other hand, assessing whether outcomes are monitored to check whether processes are effective (outcome dimension).

Employee and value chain behavior is crucial for complying with EUT MS. TERNA ENERGY Group is committed to ethical business conduct, as detailed in its Code of Conduct, and aligns its operations with the UN's 17 Sustainable Development Goals and national energy targets. Corporate responsibility is integrated into the Group’s Sustainable Development Policy, adhering to ESG (Environmental-Social-Governance) criteria across the four MS dimensions.

Annual training is mandatory for employees and part of the Group’s business strategy. In supply chain and business relationships, the same ethical conduct is expected as within the Group. MS requirements are embedded in business contracts and the Supplier's Code of Conduct, promoting practices for human rights, ethics, environmental protection, safety, meritocracy, transparency, product quality, and fair competition. Suppliers must uphold these ethical principles and ensure compliance among employees and subcontractors. Supplier selection and evaluation processes include due diligence on human rights, anti-corruption, and anti-bribery. Additionally, the Group regularly assesses complaints related to ethics, integrity, and compliance, adjusting procedures as needed.

Human Rights (including labor and consumer rights)

In alignment with the United Nations Guiding Principles on Business and Human Rights (UNGPs) and the OECD Guidelines for Multinational Enterprises, including the OECD Due Diligence Guidance for Responsible Business Conduct, a comprehensive approach has been implemented to identify, prevent, and address any actual or potential negative impacts on human rights. The publicly accessible human rights statement outlines the strategy, high-impact areas, and the measures and processes in place to prevent adverse human rights impacts. This strategy is underpinned by a detailed impact analysis that encompasses all business units and subsidiaries.

Procedures are established to ensure swift remedial action in the event of a serious human rights violation, providing necessary support to affected individuals. The effectiveness of these processes is closely monitored through inspections at facilities and construction sites by qualified personnel, alongside regular reviews of legislative and regulatory changes. A grievance mechanism is available for individuals who believe their human rights have been compromised by the activities of TERNA ENERGY Group or its value chain partners.

During the financial year 2024, TERNA ENERGY Group has not been convicted of any violation of labor law or human rights. In addition, TERNA ENERGY Group has not been involved in a case dealt with by an OECD National Contact Point and was not questioned by the Business and Human Rights Resource Center (BHRRC).

Corruption and bribery

Anti-corruption is a fundamental component of TERNA ENERGY Group's business strategy and Code of Conduct. To prevent and address corrupt practices, the Group develops specific control measures across its activities, following a thorough risk assessment, to deter and avoid corruption and bribery. In alignment with this commitment, an Anti-Corruption and Bribery Management System is installed and operational, based on the ISO 37001 standard requirements. An anti-corruption policy has been published and communicated to employees, suppliers, and business partners, and is publicly accessible on the Group's website. Regular training on anti-corruption rules and their application is mandatory for employees, with specialized training provided to those identified as being particularly exposed to corruption risks.

(Amounts in thousands of Euros unless mentioned otherwise)

67

In the financial year 2024, zero violations of corruption and bribery have been reported.

Taxation

In line with ethical business values, tax governance and tax compliance are important elements of oversight, with a commitment to complying with all relevant tax laws and regulations. The tax governance framework is based on the assessment of selected relevant risks and the application of appropriate safeguards, managed by a team of dedicated and qualified employees who work closely with Group management. Therefore, the approach to tax compliance is transparent, sustainable in the long term, and complies with the Code of Conduct.

In the financial year 2024, TERNA ENERGY Group has not been convicted in court for any major violation of tax laws.

Fair competition

All activities are conducted in accordance with applicable competition laws and regulations, taking into account the laws of all jurisdictions where activities might have anti-competitive effects. The Group's guidelines for fair competition and ethical business conduct aim to achieve and maintain fair competition in a free market environment for the entire group by fostering a corresponding corporate culture. These guidelines assist employees in preventing, detecting, and addressing any competition violations. Raising awareness and providing training that addresses competition law risks associated with business activities are of particular importance to ensure fair competition.

In 2024, there were no convictions of violation of competition laws in court for the Group.

7.10Accounting policy, definitions and additional information

The consolidated financial statements for TERNA ENERGY Group for 2024 fiscal year (FY2024) have been prepared in compliance with the International Financial Reporting Standards (IFRS). The subsequent sections provide details about the turnover, capital expenditures (CapEx), and operational expenditures (OpEx) of the Group's subsidiaries, which were previously introduced in this report. By converting the Group's environmentally sustainable practices and outcomes into financial metrics such as turnover, CapEx, and OpEx, investors and financial institutions can gain a clear understanding, enabling them to make well-informed and strategic decisions. The method used to calculate the eligibility and alignment key performance indicators (KPIs) is described below.

Turnover KPI

Definition

The proportion of Taxonomy-aligned economic activities in the Group’s total turnover has been calculated as part of net turnover derived from products and services associated with Taxonomy-aligned economic activities (numerator) divided by the net turnover (denominator) for the financial year from 1.1.2024 to 31.12.2024.

The denominator of the turnover KPI is based on the consolidated net turnover in accordance with IAS 1.82(a). cf. note 4.1.9 Revenue of the Annual Financial Report for the Year 2024.

The numerator for the turnover KPI is defined as the net turnover derived from goods and services related to economic activities aligned with the Taxonomy, i.e.

▪Activity 4.1 “Electricity generation using solar photovoltaic technology” generates net turnover from supplying energy into the energy grid

▪Activity 4.3 “Electricity generation from wind power” generates net turnover from supplying energy into the energy grid

▪Activity 4.5 “Electricity generation from hydropower” generates net turnover from supplying energy into the energy grid

▪Activity 4.8 “Electricity generation from bioenergy” generates net turnover from supplying energy into the energy grid.

Activity 4.10 Storage of electricity is not included in the FY2024 turnover, as these projects are currently under construction.

Reconciliation

The consolidated net turnover can be reconciled to the consolidated financial statements, see Consolidated Statement of Comprehensive Income of our Annual Financial Report for FY2024 (“Revenue”).

Capital expenditure (CapEx)

Definition

The CapEx KPI is defined as Taxonomy-aligned CapEx (numerator) divided by the total CapEx (denominator). Total CapEx consists of additions to tangible fixed assets (IAS 16), intangible fixed assets (IAS 38), right-of-use assets (IFRS 16) and investment properties (IAS 40) during the fiscal year, before depreciation, amortization, and any re-measurements, including those resulting from revaluations and impairments, as well as excluding changes in fair value. Additions resulting from business combinations are also included. Goodwill is not included in CapEx, as it is not defined as an intangible asset in accordance with IAS 38. For further details on the accounting policies regarding CapEx, see note 4.1.3 Intangible assets and 4.1.4 Tangible assets for FY2024.

The numerator consists of the following categories of Taxonomy-eligible CapEx:

1.CapEx related to assets or processes that are associated with Taxonomy-aligned economic activities (“category A”):

Assets and processes are associated with Taxonomy-aligned economic activities when they are essential components necessary to execute an economic activity. Consequently, all CapEx invested into the following areas are considered in the numerator of the CapEx KPI:

▪the solar photovoltaic plants (under activity 4.1)

▪the wind farms (under activity 4.3)

▪the hydropower plants (under activity 4.5)

▪the biogas plant (under activity 4.8)

▪the pumped hydropower storage projects (under activity 4.10)

We generally follow the generation of external revenues as a guiding principle to identify economic activities that are associated with CapEx under category A.

2.CapEx that are part of a plan (“CapEx Plan”) to upgrade a Taxonomy-eligible economic activity in order to become Taxonomy-aligned or to expand a Taxonomy-aligned economic activity (“category B”):

No specific upgrade plans have been set since there are no activities in the TERNA ENERGY Group portfolio classified as Taxonomy-eligible and non-aligned. Moreover, there are no specific plans to expand economic activities aligned with the EUT Regulation, as the Group’s core business involves electricity generation from RES.

3.CapEx related to the purchase of output from Taxonomy-aligned economic activities and individual measures enabling certain targeted activities to become low-carbon or lead to greenhouse gas reductions (“category C”).

Reconciliation

Total CapEx can be reconciled to the consolidated financial statements, see Chapter 8 Intangible Assets, 9 Rights in use of Assets and 10 Tangible Assets of our Annual Financial Report for FY 2024 (“table of changes in intangible assets, in right-of-use assets, in tangible assets”). They are the total of the movement types (acquisition and production costs):

▪Additions

▪Additions through business combinations for intangible assets, rights to use property, plant and equipment and property, plant and equipment

To avoid double counting in the capital expenditure (and operating expenditure) indicator, capital expenditure (and operating expenditure) related to purchased products and sub-measures already considered in "category a" (i.e., capital expenditure and operating expenditure related to assets or processes associated with economic activities aligned with the Taxonomy) is counted only once. Due to limited verification of individual investments by most suppliers, most aligned capital expenditures relate to activities 4.1, 4.3, 4.5, 4.8, and 4.10, and the individual assessment of capital expenditures does not have a material impact on aligned key performance indicators (KPIs).

Operating Expenditures (OpEx)

Definition

The OpEx KPI is defined as Taxonomy-aligned OpEx (numerator) divided by total OpEx (denominator). Total OpEx includes direct non-capitalized costs related to research and development, building renovation measures, short-term leases, maintenance and repair, and other direct expenditures for the day-today servicing of assets of property, plant, and equipment. This includes:

▪Research and development expenses recognized during the reporting period as detailed in the Statement of Comprehensive Income within the Annual Financial Report for 2024. In accordance with the consolidated financial statements (IAS 38.126), this includes all non-capitalized costs directly attributable to research or development activities.

▪Non-capitalized lease volumes determined under IFRS 16, covering expenses for short-term and low-value leases (refer to note 35 on Cost of sales, administrative, and research & development expenses in

74

the Annual Financial Report for 2024). Although low-value leases are not specifically mentioned in the Disclosures Delegated Act, they have been interpreted to be included.

▪Maintenance, repair, and other direct expenditures for the day-to-day servicing of property, plant, and equipment assets, determined based on maintenance and repair costs. These costs appear in various line items within the Statement of Comprehensive Income, including production costs (maintenance in operations), sales and distribution costs (maintenance logistics), and administration costs (such as IT system maintenance). Building renovation measures are also included.

In general, this involves staff costs, service costs, and material costs for daily servicing, as well as for regular and unplanned maintenance and repair activities, all directly allocated to PP&E. Exclusions from the OpEx KPI include expenditures related to the day-to-day operation of PP&E, such as raw materials, employee costs for machine operation, and utilities necessary for PP&E operation. Amortization and depreciation are also excluded.

Direct costs for training and other human resources adaptation needs are excluded from both the denominator and numerator, as Annex I to the Disclosures Delegated Act lists these costs only for the numerator, preventing a mathematically meaningful calculation of the OpEx KPI.

Additional Clarifications: For FY2024, no extra allocation keys for personnel expenses connected to asset maintenance were applied due to lack of sufficient information. Other production personnel expenses are excluded from operating costs as per the EUT guidelines.

Contextual information

On November 28th 2024, Masdar, the United Arabic Emirates’ (UAE) clean energy leader, acquired 70% of TERNA ENERGY Group’s outstanding shares to become majority shareholder. The acquisition reflects Masdar's confidence in the Group’s growth plan targeting renewable energy operational capacity of 6GW by 2029, as well as the strength of the Greek market and its renewables sector.

Due to the acquisition and subsequent changes in the Group’s other business segments (non RES related business segments), changes across the Group’s KPI denominators compared to the previous reporting year FY2023 occurred. Moreover, CapEx is notably lower compared to the previous reporting year due to the completion of RES projects that were under construction now in operation. Finally, significant increase of the aligned proportion of Turnover and OpEx KPIs is noted compared to FY2023 considering the operation of several RES projects in FY2024 and the increase in RES R&D activities during the reporting year.

Turnover KPI

Quantitative analysis of the numerator

A quantitative analysis of the turnover’s numerator is presented below, where revenue is listed by geographic area of operation. In FY2024, no key drivers of change were identified compared to the previous reporting year 2023. Nonetheless, significant increase of the aligned proportion of Turnover KPI is noted compared to FY2023, mainly due to the commencement of operation of several RES projects in FY2024.

For the implementation of the above, the Board of Directors determines the operating framework of internal audit, approves the procedures for conducting and evaluating its results and decides on its staffing, in compliance with the requirements of the applicable legal and institutional framework as well as the Hellenic

7.Sustainability Policy

The Company has a Suitability Policy for the Members of the Board of Directors, which was prepared by its Nominations Committee in accordance with the provisions of article 3 of Law 4706/2020 and the guidelines of Circular no. 60 of the Hellenic Capital Market Commission.

The Policy was approved by the General Assembly of the Company's shareholders dated 23.06.2021 following the approval of the Board of Directors dated 02.06.2021 and entered into force from the date of its approval by the General Assembly. Individual amendments require re-approval by the Board of Directors, while the Review of the Policy requires a Decision of the General Assembly.

Revision is characterized by the adoption of substantial amendments that introduce significant deviations or also significantly change the content of the Policy, in particular in terms of the applied principles and criteria or the original writing of the Policy.

In addition, the increased monitoring needs of the framework of Corporate Governance, Risk Management, Compliance, as well as the operation of Company Sectors such as Human Resources, Information Technology, Information Security Management, Health, Safety and Environment were taken into account, with management or supervision responsibilities assigned to executive members of the BoD. At the same time, the possibility of contributing to the responsibilities and/or technical support of the Board Committees was taken into account.

The Suitability Policy aims to ensure quality staffing, effective operation and fulfillment of the role of the Board of Directors based on the overall strategy and medium to long-term business objectives of the Company, with the aim of promoting the corporate interest.

The aim of this policy is to have a highly effective Board of Directors. As such, it is considered a Board of Directors with a structured team, working together with a shared commitment to protecting and enhancing shareholder value, rather than a typical gathering of executives who manage corporate affairs without the capacity for constructive cooperation and growth prospects.

The Policy takes into account best practices and is harmonized with the corporate culture and what is provided for in the Articles of Association, the Internal Rules of Operation and the Hellenic Corporate Governance Code to which the Company is subject, is clear and adequately documented and is governed by the principle of transparency and proportionality while promoting diversity, meritocracy and efficiency in the selection and during the term of office of the members of the Board.

(Amounts in thousands of Euros unless mentioned otherwise)

112

Furthermore, during the preparation of the Policy, the size, internal organization, risk appetite, nature, scale and complexity of the Company's activities were taken into account, which during 2024 included, but not limited to, the sectors of construction, concessions, energy, real estate management and development, mining, waste management, services, PPP projects, the operation of large infrastructure projects.

The guiding principles governing this policy are as follows:

•Compliance

•Transparency

•Proportionality

•Diversity

•Meritocracy

•Effectiveness

•Experience and historicity

8.Diversity policy

The Company has and implements a diversity policy in order to promote an appropriate level of differentiation in the Board of Directors and a diverse group of members. The Policy is based on the belief that a Board of Directors that has a wide range of perspectives and diversity is in a better position than other Boards of Directors with a limited scope, as the existence of diversity allows the Company to exploit market opportunities and effectively manage risks.

The Board can perform well if it consists of a wide range of members with diverse but complementary groups of skills or knowledge. Its culture is positively shaped by different approaches and views and will certainly be quite representative of the Group's values. In this way, the Board of Directors ultimately forms a progressive and thoughtful view of its affairs, while promoting prudent risk-taking.

Through the accumulation of a wide range of qualifications and skills during the selection of Board members, the diversity of views and experiences is ensured, in order to make sound decisions.

In this context, adequate representation per gender is provided, at least as defined by the relevant legislation, as a percentage of the total members of the Board of Directors. At the same time, all necessary measures are taken so that there is no exclusion whatsoever due to discrimination based on sex, age, race, color, ethnic or social origin, religion or belief, birth, disability, age or sexual orientation, property and sole role of choice to have the criteria of individual suitability identified in this Policy.

The achievement of substantial and not only formal diversity within the Boards of Directors is an important guarantee for the overall effectiveness of the Board of Directors.

9.Transactions with related parties and relevant information of the Board of Directors

The Company has developed a procedure for identifying related party transactions and complying with applicable law. The process was drafted in the context of transparency and supervision of the Company's transactions with related parties. The purpose of the procedure is to record the actions performed in order to identify transactions of the Company, in which natural or legal persons participate, falling under the concept of related parties and to comply with the applicable legislation. The procedure provides for the recording and maintenance of a register of related parties and the recognition of related party transactions through the control of the counterparty in accordance with articles 99-101 of Law 4548/2018.

10.Sustainable development policy

(Amounts in thousands of Euros unless mentioned otherwise)

113

Sustainable Development for TERNA ENERGY Group is not only a practice of alignment with international good practices but a holistic strategic approach based on the regular assessment of the most important social, economic and environmental impacts of the Group's activities and their review and/or modification if necessary, through a process of dialogue and consultation with stakeholders.

Furthermore, TERNA ENERGY Group acts in accordance with the United Nations (UN) Global Sustainable Development Goals (SDGs) and is an ally in the fight for social equality, prosperity and the development of a sustainable natural environment, given that it has recognized that the seventeen (17) global goals are inextricably linked to the principles of Corporate Governance and Corporate Social Responsibility / Sustainable Development to which it is committed.

The responsible operation of the Group is reflected in the practices and procedures developed in the Group aiming at integrating the principles of Sustainable Development into its daily operation. At the same time, it is based on the strategic corporate values established by the Management, namely respect for people and the natural environment, value creation for employees, customers and shareholders, honesty, reliability and targeted social contribution.

The Group's policy for Sustainable Development is inextricably linked to the material issues that are regularly identified through the materiality analysis process, in order for the Group to constantly listen to the needs of stakeholders (internal and external) but also to take into account the current socio-economic trends in relation to its effects (positive or negative).

In this context, the Group's corporate responsibility is aligned with the ESG (Environmental-Social-Governance) criteria/principles, concerns four (4) axes of activity and is developed in eight (8) strategic directions/individual areas that incorporate the Group's specific approach-policy regarding the identified material issues:

Axis 1: Environmental Protection

The achievement of sustainable development through the continuous reduction of the environmental footprint of the Group's activities in Greece and abroad, the continuous adaptation to the conditions for Climate Change and the implementation of the principles of Circular Economy in combination with the investment in innovative services and technologies and the loyal adherence to the existing environmental management system.

Environmental protection is an integral part of the Group's strategy and becomes visible through its policies, strategies and business decisions and actions. The Group acts in a targeted manner and takes measures that lead to the reduction of its environmental and energy footprint through the responsible management of energy and the natural resources it uses (e.g. water, energy, materials, tackling Climate Change and protecting and preserving biodiversity). It focuses on the transition to an economy that is less dependent on fossil fuels and ensures sustainable cities and societies for all its stakeholders.

Axis 2: Promotion of Human Value

Strategic Direction / Area of Activity: Health & Safety at Work

The recognition of the value of human health and life and the assurance of a working environment without risks of accidents.

(Amounts in thousands of Euros unless mentioned otherwise)

114

Safeguarding Health and Safety is a priority for the Group, which is constantly improving the strategic framework within which issues related to the protection of Health and Safety of all its stakeholders are managed.

Strategic Direction / Area of Activity: Personnel development and protection of human rights

The recognition that surplus value is created by human capital. The aim is to develop a balanced and safe working environment of meritocracy, transparency, equal opportunities-benefits, which enhances diversity, ensures human - labor rights and at the same time invests in the continuous improvement of employees' skills, the development and retention of talents and the strengthening of youth entrepreneurship.

The Group applies and respects international principles and standards of Human Rights and has developed its framework of principles and values based on fundamental Human Rights. Respecting all its employees and partners, it ensures the prevention of incidents of violation of their rights, through the adoption of policies, actions and control mechanisms, which apply and apply to all its activities, to all its subsidiaries and to all the projects it undertakes. The Group actively participates, supports and considers as a top priority the investment in its people by providing the necessary resources to promote the continuous improvement of the working environment.

Axis 3: Strengthening the Social Footprint

The continuous consultation with the social partners and the preparation of social impact studies with the ultimate goal of maximizing direct and indirect social benefits, the support of solidarity actions such as donations and sponsorships and the constant cooperation with local suppliers to build long-term relationships of trust.

Through the adoption of responsible policies aimed at creating shared value to all its stakeholders, the Group supports the development of the local communities in which it operates and with which it interacts, through continuous consultation and efforts to identify and respond to the real needs that exist, but also through its own activity.

Strategic Direction/Area of Activity: Emergency response

The commitment to take measures and actions to deal with emergencies through the development of risk management plans, the implementation of preparedness exercises and the realization of periodic internal and external audits.

Axis 4: Shaping a Responsible Market

Strategic Direction / Area of Activity: Creation and distribution of economic value

The creation of economic value - the main objective of the Group is to generate and distribute income for its stakeholders through the payment of salaries to employees, payments to suppliers and partners, direct and indirect taxes in the states of operation, the distribution of dividends to shareholders and investments in local communities while avoiding uncertainties and risks, financial and non-financial, with the aim of safeguarding economic activity, sustainable development and improving living standards.

Strategic Direction / Area of Activity: Business ethics and regulatory compliance

The Group ensures the assurance of business ethics and regulatory compliance of all its operations and activities, having as a priority the detection and combating of potential corruption incidents, faithfully applying the procedures and policies incorporated in the corporate operation (Code of Ethics and Ethics, Anti-Bribery Management System ISO 37001), and the regular training of human resources.

(Amounts in thousands of Euros unless mentioned otherwise)

115

The fight against corruption is a critical pillar of the Group's operation, which is committed to showing zero tolerance to such incidents, through the promotion of transparency, ensuring business ethics and regulatory compliance, which are diffused across the spectrum of activities and affect the professional behavior of its people. To this end, the Group acts through the establishment of policies and procedures, but also through the establishment of control mechanisms and compliance with these policies.

Strategic Direction / Area of Activity: Responsible supply chain management

Responsible supply chain management requires responsible partnerships. Therefore, it is mandatory for all suppliers and partners to fully comply with the Group's Regulatory Framework of Principles and Values, both in matters of corruption and respect for human rights, as well as in matters of Environmental Management and Social Corporate Policy.

Above all, the proper management of the supply chain starts from the responsible attitude of the Group towards all its stakeholders. The Group's business activities throughout its supply chain are carried out once the potential environmental, social and economic impacts have been assessed in order to maximize the positive impact. In order to address the new challenges brought by supply chain issues, the Group makes sure to incorporate new criteria in the management procedures of supply chain issues, such as the new terms of cooperation with suppliers and the preference it gives to domestic suppliers.

For the above issues, the Group sets individual Sustainable Development goals, which it evaluates on an annual basis in terms of their progress and revises them appropriately when necessary.

In order to achieve the objectives, the Group develops individual management systems, policies, procedures, measurement indicators and implements appropriate action plans / programs that contribute to the increase of positive effects or the reduction of negative ones.

The mandated corporate responsibility team is responsible for the effective management of Sustainable Development and corporate responsibility issues. The team consists of specialized executives coming from all key Group Divisions. The Division for Strategic Communication, Press Office, CSR and Sustainable Development has undertaken the task of coordination.

The Chairman and CEO, through the direct reference line of the Strategic Communication, Press Office, CSR and Sustainable Development Division, has undertaken the overall management / supervision of Sustainable Development issues, sealing the commitment of the Group's top management towards a sustainable operation.

With a view to transparency and regular information to stakeholders, the results of the Group's performance on Sustainable Development issues are published to the general public through the annual Sustainable Development Report.

IV.INDEPENDENT AUDITOR’S REPORT

(Translated from the original in Greek)
To the Shareholders of Terna Energy S.A.
Report on the Audit of the Separate and Consolidated Financial Statements
Opinion
We have audited the Separate and Consolidated Financial Statements of Terna Energy S.A. (the “Company”) which comprise the Separate and Consolidated Financial Position as at 31 December 2024, the Separate and Consolidated Statements of Comprehensive Income, Changes in Equity and Cash Flow for the year then ended, and notes, comprising material accounting policies and other explanatory information. In our opinion, the accompanying Separate and Consolidated Financial Statements present fairly, in all material respects, the separate and consolidated financial position of Terna Energy S.A. and its subsidiaries (the “Group”) as at 31 December 2024 and its separate and consolidated financial performance and its separate and consolidated cash flows for the year then ended, in accordance with International Financial Reporting Standards (IFRS), as adopted by the European Union.
Basis for Opinion
We conducted our audit in accordance with International Standards on Auditing (ISA), as incorporated in Greek legislation. Our responsibilities under those standards are further described in the Auditor’s Responsibilities for the Audit of the Separate and Consolidated Financial Statements section of our report. We are independent of the Company and the Group in accordance with the International Ethics Standards Board for Accountants International Code of Ethics for Professional Accountants, as incorporated in Greek legislation, and with the ethical requirements that are relevant to the audit of the separate and consolidated financial statements in Greece and we have fulfilled our other ethical responsibilities in accordance with the requirements of the applicable legislation. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.
Key Audit Matters

117

Key audit matters are those matters, that, in our professional judgment, were of most significance in our audit of the Separate and Consolidated Financial Statements of the current period. These matters and the relevant significant assessed risks of material misstatement were addressed in the context of our audit of the Separate and Consolidated Financial Statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters.
Impairment Assessment of non-current assets
See Notes 3.1(ii), 3.2(iv), 4.1.1 (α), 4.1.3, 4.1.4, 4.1.5, 8, 10 and 11 to the Separate and Consolidated Financial Statements.
The key audit matter	How the matter was addressed in our audit

118

As of 31 December 2024, the Group has recognized “Tangible Assets” amounting to EUR 1 408 million and “Intangible Assets” amounting to EUR 68 million in the consolidated financial statements which mostly concern the operating sector "Electricity and Renewable Energy Sources". In the separate financial statements as of 31 December 2024, the Company has recognized “Tangible Assets” amounting to EUR 69 million, “Intangible Assets” amounting to EUR 4 million and investments in subsidiaries amounting to EUR 360 million which are accounted for at cost, adjusted for any impairment where necessary.

In accordance with IFRS, management performs impairment tests for Tangible Assets and Tangible Assets with definitive useful lives at the end of each reporting period, when indications exist that the carrying value of each Cash Generating Unit (CGU) exceeds its recoverable amount. Respectively, regarding the investments in subsidiaries, the impairment is examined when relevant indications exist.

The Group assesses the recoverable amount of CGUs/subsidiaries based on value in use. The calculation of value in use requires estimates by Management relating to variables as production of electricity, the selling price of electricity, the budgeted net operating profits, earnings before financial and investing activities, depreciation and amortization and impairments, the discount rate and the current and future market conditions.

The above estimates require significant judgement from the Management and include a level of uncertainty. Consequently, we consider the impairment assessment and the impairment exercise of non-current assets, where needed, as a key audit matter.

Disclosures regarding the assumptions and the methodology used for the calculation of the impairment are important to provide clarity

Regarding this matter, our audit procedures included, among others, the following:

1.We examined management’s assessment and analysis regarding the existence of indications of impairment of non-current assets.

2.For the CGU where indications of impairment exist, we performed the following:

A.With the support of our valuation experts:

iwe evaluated the appropriateness of the methods applied for the identification of recoverable amount of CGUs;

iiwe evaluated the reasonableness of the key assumptions and estimates of future cash flows. The key assumptions that were evaluated included the electricity production, the selling price of electricity, the budgeted net operating profits revenue, the earnings before financial and investing activities, depreciation and amortization and impairments and the discount rate used in the future cash flow projections;

iiiwe performed a sensitivity analysis on the key assumptions adopted;

ivour assessment also included a comparison of the key assumptions used in management's valuation models, with external data and market trends, our knowledge of the Company and the industry as well as the assumptions used in the previous year and

vwe confirmed the mathematical accuracy of discounted cash flow models for the identification of value in use of CGUs.

B.We evaluated the reliability of management’s estimates during the preparation of the business plans, by comparing the previous budget and estimates to the actual

Other Information
The Board of Directors is responsible for the other information. The other information comprises the information included in the Board of Directors’ Report, for which reference is made in the “Report on Other Legal and Regulatory Requirements” and the Declarations of the Members of the Board of Directors but does not include the Separate and Consolidated Financial Statements and our Auditor’s Report thereon. Our opinion on the Separate and Consolidated Financial Statements does not cover the other information and we do not express any form of assurance conclusion thereon. In connection with our audit of the Separate and Consolidated Financial Statements, our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the Separate and Consolidated Financial Statements, or our knowledge obtained in the audit, or otherwise appears to be materially misstated. If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact. We have nothing to report in this regard.
Responsibilities of the Board of Directors and Those Charged with Governance for the Separate and Consolidated Financial Statements

120

The Board of Directors is responsible for the preparation and fair presentation of the Separate and Consolidated Financial Statements in accordance with IFRS as adopted by the European Union, and for such internal control as the Board of Directors determines is necessary to enable the preparation of separate and consolidated financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the Separate and Consolidated Financial Statements, the Board of Directors is responsible for assessing the Company’s and the Group’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the Board of Directors either intends to liquidate the Company and the Group or to cease operations, or has no realistic alternative but to do so.

The Audit Committee of the Company is responsible for overseeing the Company’s and the Group’s financial reporting process.

Auditor’s Responsibilities for the Audit of the Separate and Consolidated Financial Statements

121

Our objectives are to obtain reasonable assurance about whether the Separate and Consolidated Financial Statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditors’ report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with ISAs which have been incorporated in Greek legislation will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these Separate and Consolidated Financial Statements.

As part of an audit in accordance with ISAs, which have been incorporated in Greek legislation, we exercise professional judgment and maintain professional skepticism throughout the audit. We also:

•Identify and assess the risks of material misstatement of the separate and consolidated financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.

•Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s and the Group’s internal control.

•Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by the Board of Directors.

•Conclude on the appropriateness of the Board of Directors’ use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Company’s and the Group’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditors’ report to the related disclosures in the Separate and Consolidated Financial Statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditors’ report. However, future events or conditions may cause the Company or the Group to cease to continue as a going concern.

•Evaluate the overall presentation, structure, and content of the Separate and Consolidated Financial Statements, including the disclosures, and whether the separate and consolidated financial statements represent the underlying transactions and events in a manner that achieves fair presentation.

•Plan and perform the group audit to obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the Group to express an opinion on these Group Financial Statements. We are responsible for the direction, supervision and review of the audit work performed for purposes of the group audit. We remain solely responsible for our audit opinion.

We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit.

We also provide those charged with governance with a statement that we have complied with relevant ethical requirements regarding independence and communicate with them all relationships and other matters that may reasonably be thought to bear on our independence,

122

Our objectives are to obtain reasonable assurance about whether the Separate and Consolidated Financial Statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditors’ report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with ISAs which have been incorporated in Greek legislation will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these Separate and Consolidated Financial Statements. As part of an audit in accordance with ISAs, which have been incorporated in Greek legislation, we exercise professional judgment and maintain professional skepticism throughout the audit. We also: Identify and assess the risks of material misstatement of the separate and consolidated financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.

We also provide those charged with governance with a statement that we have complied with relevant ethical requirements regarding independence and communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, related safeguards. From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of the Separate and Consolidated Financial Statements of the current period and are therefore the key audit matters. We describe these matters in our auditor’s report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.

2.3Basis of measurement

The hereby Consolidated and Separate Financial Statements as of December 31st, 2024 have been prepared according to the principle of historical cost, apart from financial derivatives, liability for contingent consideration, investments in equity instruments and other short term investments, which are being measured at fair value.

2.4Presentation currency

The reporting currency is Euro (the currency of the Group’s parent Headquarters) and all the amounts are presented in thousand Euro unless otherwise mentioned.

2.5Comparability

The comparative figures of the Group and the Company for the financial year 2023,as presented in the Statement of Comprehensive Income, Cash Flow Statement and Statement of Changes in Equity have been revised in order to include only continuing operations, as a consequence of the recognition as discontinued operations of the Group's Construction and Concessions segments, in accordance with the requirements of IFRS 5 "Non-current assets held for sale and discontinued operations" following the completion of the acquisition of the shares of TERNA ENERGY S.A. from Abu Dhabi Future Energy Company PJSC - Masdar ('Masdar') by GEK TERNA S.A. and other shareholders, and the simultaneous assignment to GEK TERNA Group of the construction activities of public works, infrastructure-related concessions and other projects of public interest as well as all renewable energy research activities in the United States, (see Management Report and Notes 5 and 7).

2.6New Standards, Interpretations and Amendments of Standards

The accounting principles applied for the preparation of the financial statements are the same as those followed in the preparation of the financial statements of the Group and the Company for the year ended 31st of December 2023, except for the adoption of the amendments of certain standards, the application of which became mandatory in the European Union for fiscal years beginning on 1 January 2024 (see Notes 2.6.1 and 2.6.2).

2.6.1New Standards, Interpretations, Revisions and Amendments to existing Standards that are effective and have been adopted by the European Union

The following new Standards, Interpretations and amendments of IFRSs have been issued by the International Accounting Standards Board (IASB), are adopted by the European Union, and their application is mandatory from or after 01/01/2024.

Amendments to IAS 1 “Classification of Liabilities as Current or Non-current” (effective for annual periods starting on or after 01/01/2024)

The amendments clarify the principles of IAS 1 for the classification of liabilities as either current or non‐current. The amendments clarify that an entity’s right to defer settlement must exist at the end of the reporting period. The classification is not affected by management’s intentions or the counterparty’s option to settle the liability by transfer of the entity’s own equity instruments. Also, the amendments clarify that only covenants with which an entity must comply on or before the reporting date will affect a liability’s classification. The amendments require a company to disclose information about these covenants in the notes to the financial statements. The amendments are effective for annual reporting periods beginning on

TERNA ENERGY GROUP

Annual Financial Report for the year 2024

(Amounts in thousands of Euros unless mentioned otherwise)

140

or after 1 January 2024. The amendments do not affect the consolidated and separate Financial Statements. The above have been adopted by the European Union with effective date of 01/01/2024.

Amendments to IFRS 16 “Leases: Lease Liability in a Sale and Leaseback” (effective for annual periods starting on or after 01/01/2024)

In September 2022, the IASB issued narrow-scope amendments to IFRS 16 “Leases” which add to requirements explaining how a company accounts for a sale and leaseback after the date of the transaction. A sale and leaseback is a transaction for which a company sells an asset and leases that same asset back for a period of time from the new owner. IFRS 16 includes requirements on how to account for a sale and leaseback at the date the transaction takes place. However, IFRS 16 had not specified how to measure the transaction when reporting after that date. The issued amendments add to the sale and leaseback requirements in IFRS 16, thereby supporting the consistent application of the Accounting Standard. These amendments will not change the accounting for leases other than those arising in a sale and leaseback transaction. The amendments do not affect the consolidated and separate Financial Statements. The above have been adopted by the European Union with an effective date of 01/01/2024.

Amendments to IAS 7 “Statement of Cash Flows” and IFRS 7 “Financial Instruments: Disclosures”: Supplier Finance Arrangements (effective for annual periods starting on or after 01/01/2024)

In May 2023, the International Accounting Standards Board (IASB) issued Supplier Finance Arrangements, which amended IAS 7 Statement of Cash Flows and IFRS 7 Financial Instruments: Disclosures. The new amendments require an entity to provide additional disclosures about its supplier finance arrangements. The amendments require additional disclosures that complement the existing disclosures in these two standards. They require entities to provide users of financial statements with information that enable them a) to assess how supplier finance arrangements affect an entity’s liabilities and cash flows and b) to understand the effect of supplier finance arrangements on an entity’s exposure to liquidity risk and how the entity might be affected if the arrangements were no longer available to it. The amendments to IAS 7 and IFRS 7 are effective for accounting periods on or after 1 January 2024. The amendments do not affect the consolidated and separate Financial Statements. The above have been adopted by the European Union with effective date of 01/01/2024.

2.6.2New Standards, Interpretations, Revisions and Amendments to existing Standards that have not been applied yet or have not been adopted by the European Union until

The following new Standards, Interpretations and amendments of IFRSs have been issued by the International Accounting Standards Board (IASB), but their application has not started yet or they have not been adopted by the European Union.

IFRS 9 & IFRS 7 “Amendments to the Classification and Measurement of Financial Instruments” (effective for annual periods starting on or after 01/01/2026)

In May 2024, the International Accounting Standards Board (IASB) issued amendments to the Classification and Measurement of Financial Instruments which amended IFRS 9 “Financial Instruments” and IFRS 7 “Financial Instruments: Disclosures”. Specifically, the new amendments clarify when a financial liability should be derecognized when it is settled by electronic payment. Also, the amendments provide additional guidance for assessing contractual cash flow characteristics to financial assets with features related to ESG-linked features (environmental, social, and governance). IASB amended disclosure requirements relating to investments in equity instruments designated at fair value through other comprehensive income and added disclosure requirements for financial instruments with contingent features that do not relate directly to basic

lending risks and costs. The amendments are effective from annual reporting periods beginning on or after 1 January 2026. The Group will examine the impact of the above on its Financial Statements. The above have not been adopted by the European Union.

Annual Improvements to IFRS Standards-Volume 11 (effective for annual periods starting on or after 01/01/2026)

In July 2024, the IASB issued the Annual Improvements to IFRS Accounting Standards-Volume 11 addressing minor amendments to the following Standards: IFRS 1 ‘First-time Adoption of International Financial Reporting Standards’, IFRS 7 ‘Financial Instruments: Disclosures’, IFRS 9 ‘Financial Instruments’: IFRS 10 ‘Consolidated Financial Statements’, and IAS 7 ‘Statement of Cash Flows’. The amendments are effective for accounting periods on or after 1 January 2026. The Group will examine the impact of the above on its Financial Statements. The above have not been adopted by the European Union.

Amendments to IFRS 9 and IFRS 7 “Contracts Referencing Nature-dependent Electricity” (effective for annual periods starting on or after 01/01/2026)

On 18 December 2024 the International Accounting Standards Board (IASB) issued amendments to IFRS 9 “Financial Instruments” and IFRS 7 “Financial Instruments: Disclosures” to help companies better report the financial effects of nature-dependent electricity contracts, which are often structured as power purchase agreements (PPAs). Nature-dependent electricity contracts help companies to secure their electricity supply from sources such as wind and solar power. The amount of electricity generated under these contracts can vary based on uncontrollable factors such as weather conditions. The amendments allow companies to better reflect these contracts in the financial statements, by a) clarifying the application of the ‘own-use’ requirements, b) permitting hedge accounting if these contracts are used as hedging instruments and c) adding new disclosure requirements to enable investors to understand the effect of these contracts on a company’s financial performance and cash flows. The amendments are effective for accounting periods on or after 1 January 2026, with early application permitted. The Group will examine the impact of the above on its Financial Statements. The above have not been adopted by the European Union.

IFRS 18 “Presentation and Disclosure in Financial Statements” (effective for annual periods starting on or after 01/01/2027)

In April 2024 the International Accounting Standards Board (IASB) issued a new standard, IFRS 18, which replaces IAS 1 ‘Presentation of Financial Statements’. The objective of the Standard is to improve how information is communicated in an entity’s financial statements, particularly in the statement of profit or loss and in its notes to the financial statements. Specifically, the Standard will improve the quality of financial reporting due to a) the requirement of defined subtotals in the statement of profit or loss, b) the requirement of the disclosure about management-defined performance measures and c) the new principles for aggregation and disaggregation of information. The Group will examine the impact of the above on its Financial Statements. The above have not been adopted by the European Union.

2.7Use of estimations

The preparation of the Financial Statements according to IFRS requires the use of estimates and judgments on the application of the Company’s accounting policies. Judgments, assumptions and estimates of the Management affect the amount of valuation of several asset and liability items, the amount recognized during the year regarding specific income and expenses as well as the presented estimates of contingent liabilities. Assumptions and estimates are assessed on an on-going basis according to historic experience and other factors, including expectations of future event outcomes, considered reasonable given the current

TERNA ENERGY GROUP

Annual Financial Report for the year 2024

(Amounts in thousands of Euros unless mentioned otherwise)

142

conditions. The estimates and assumptions relate to the future and, consequently, the actual results may differ from the accounting calculations.

The areas requiring the highest degree of judgment as well as the factors mostly affecting the consolidated Financial Statements are presented in Note 3 of the Financial Statements.

3.MATERIAL ACCOUNTING ESTIMATES AND MANAGEMENT ASSESSMENTS

The preparation of Financial Statements in accordance with the International Financial Reporting Standards (IFRS) requires the Management to make judgments, estimates and assumptions which affect assets and liabilities, disclosures for contingent assets and liabilities as well as revenue and expenses during the presented periods.

Particularly, amounts included in or affecting the financial statements, as well as the related disclosures, are estimated through making assumptions about values or conditions that cannot be known with certainty at the time of preparation of the financial statements and therefore actual results may differ from what has been estimated. An accounting estimate is considered significant when it is material to the financial position and income statement of the Group and requires the most difficult, subjective, or complex judgments of the Management. Estimates and judgments of the Management are based on experience and other factors, including expectations for future events that are judged to be reasonable in the circumstances. Estimates and judgments are continually reassessed based on all the available data and information.

Key estimates and evaluations referring to data whose evolution could affect the financial statements items in the upcoming 12 months are the following:

3.1 Significant management judgements

Key judgments of the Management, applied while implementing the Group and the Company accounting policies, which have the most significant impact on the financial statements (apart from those analyzed in Note 3.2), are analyzed as follows.

i)Recognition of deferred tax assets

The extent, to which deferred tax assets are recognized for unused tax losses, is based on the judgment regarding the extent, to which it is probable that sufficient taxable profits will be offset with these tax losses. To determine the amount of a deferred tax asset that can be recognized, significant judgments and estimates of the Group’s Management are required, based on future taxable profits, combined with future tax strategies to be pursued, as well as the uncertainties dominating in various tax frameworks, within which the Group operates (for further information please refer to Note 31).

ii)Impairment of non-financial assets

Non-financial assets are tested for impairment whenever events or changes in the effective conditions indicate that their book value may not be recoverable in accordance with the accounting policy described in Note 4.1.5 (for further information please refer to Notes 8 and 11).

iii)Acquisition of “business” according to the definition provided in IFRS 3 or acquisition of assets.

In accordance with IFRS 3 "Business Combinations", the Management determines whether a transaction or other event constitutes a business combination in accordance with the relevant definition of the Standard, i.e. whether the assets acquired, and liabilities assumed constitute a "business". In the event the acquired assets do not constitute a business, then the Group manages the transaction or other event as an acquisition of an asset. According to IFRS 3, the term "business" is defined as an integrated set of activities and assets that is capable of being conducted and managed for the purpose of providing a return in the form of

TERNA ENERGY GROUP

Annual Financial Report for the year 2024

(Amounts in thousands of Euros unless mentioned otherwise)

143

dividends, lower costs, or other economic benefits directly to investors or other owners, members, or participants. The accounting treatment of acquisition of an asset (or group of assets) which do not constitute a "business" is carried out in accordance with the accounting policy described in Note 4.1.11.

3.2Uncertainty of estimates and assumptions

Specific amounts that are either included or affect the Financial Statements and the related disclosures are estimated, necessitating to make assumptions about values or conditions that cannot be known with certainty during the period of the Financial Statements preparation. An accounting estimate is considered significant when it is material to the financial position and the income statement of the Group and requires the most difficult, subjective, or complex judgments of the Management. The Group assesses such estimates on an ongoing basis, based on historical results and experience, while meetings with specialists, applying trends and other methods considered reasonable in the circumstances, as well as making projections regarding potential changes in the future.

i)Recognition of revenue from construction contracts

Managing revenue and expenses from a construction contract, depends on whether the result of the contract implementation can be reliably estimated (and is expected to bring profit to the constructor or the result of the implementation are expected to be loss-bearing). When the outcome of a construction contract can be reliably estimated, then revenue and expense of the contract are recognized over the term of the contract, as revenue and expense, respectively.

The Group uses the completion stage to determine the appropriate amount of revenue and expense which it will recognize in a specific period. Based on the input method under IFRS 15, the construction cost at every reporting date is compared to the total budgeted cost to determine the percentage of completion. The completion stage is measured based on the contractual costs incurred until the reporting date in relation to the total estimated cost of every construction project. The Group, therefore, makes significant estimates regarding the gross result with which every construction contract will be implemented (total budgeted cost of the construction contract implementation).

ii)Provision for income tax

Provision for income tax based on IAS 12 is calculated by estimating the taxes to be paid to tax authorities and includes the current income tax for every financial year and a provision for additional taxes that might arise during tax inspections.

The Group’s companies are subject to various income taxation legislations. Significant estimates are required to determine the total provision for income tax, as presented in the Statement of Financial Position. The final tax determination is uncertain in respect of specific transactions and calculations. The Group recognizes liabilities for the projected tax issues based on the calculations as to the extent to which additional taxation will arise. In cases where the final tax result differs from the initially recognized amount, the differences affect the provisions for income tax and deferred tax for the period when it had been determined (for further information please refer to Note 31).

iii)Fair value measurement

The Management uses valuation techniques to determine the fair value of financial instruments (when no active market prices are available) and non-financial assets. This procedure involves making estimates and assumptions about the consideration that market participants would pay to acquire these financial instruments. The Management bases its assumptions on observable data, but this is not always feasible. In

TERNA ENERGY GROUP

Annual Financial Report for the year 2024

(Amounts in thousands of Euros unless mentioned otherwise)

144

such cases, the Management uses the best available information for its estimates, based on its past experience, also taking into account the available information. Estimated fair values may differ from the actual values that would be made in the context of an ordinary transaction at the reporting date of the financial statements (further information is provided in Note 41).

The Group uses derivative financial instruments to manage a range of risks including interest rate and commodity prices risks. For the purpose of determining an effective hedging rate, the Group requires both - to declare its hedging strategy and to estimate that the hedge will be effective throughout the term of the hedging instrument (derivative). Further information regarding the use of derivatives is provided in Note 22.

Also, any contingent consideration provided by the Group during an acquisition is measured at its initial recognition, as well as at every reporting date of the financial statements, at its fair value. Contingent consideration is measured in accordance with the accounting policy described in Note 4.1.11 (for cases where the acquisition is a business combination) and under IFRS 3, or in accordance with the accounting policy described in Note 4.1.11 (for cases when acquisitions meet the effective prerequisites to be characterized as assets) (more information is presented in Notes 7 and 29).

iv)Estimates in calculation of the value in use of non-current assets

In accordance with the applied accounting policies and the requirements of IAS 36, the Group conducts a related impairment test on the assets at the end of each annual reporting period. The relevant test, in accordance with the requirements of IAS 36, may be carried out earlier, when there are indications of contingent impairment loss. If it is established that there are reasons for impairment, it is necessary to calculate value in use and fair value less costs to sell regarding every CGU. Recoverable amounts of CGUs are determined for impairment tests purposes, based on the value in use calculation, which requires making estimates. For the calculating of calculating value in use, estimated cash flows are discounted to their present value using a discount rate that reflects current market assessments of the time value of money as well as the risks associated with particular CGU. Estimate of future operating results is based on wind farm efficiency estimates based on wind data and historical data of comparable units. The key assumptions used to determine the recoverable number of various CGUs are recorded in Note 11 of the Financial Statements.

v)Useful lives of depreciated asset

For the calculating of depreciations, the Group examines the useful life and residual value of tangible and intangible assets in every reporting period in the light of technological, institutional, and economic developments as well as the experience of their exploitation. As at 31/12/2024, the Management estimates that useful lives represent the expected usefulness of assets.

vi)Provisions for rehabilitation of environment

The Group makes provision for its related obligations to dismantle the technical equipment of wind farms and other productive facilities and restoration of the environment resulting from the applicable environmental legislation or from binding practices of the Group. Provision for rehabilitation of the environment reflects the present value, as at the reporting date (based on the appropriate discount rate) of the rehabilitation obligation less the estimated recoverable amount of the materials, estimated to be disposed of and sold (further information is provided in Notes 4.1.17 and 24).

vii)Contingent liabilities and receivables

The existence of contingent liabilities and assets requires the management to make assumptions and judgments on on-going basis about the probability that future events will occur or not occur as well as the

TERNA ENERGY GROUP

Annual Financial Report for the year 2024

(Amounts in thousands of Euros unless mentioned otherwise)

145

possible consequences that these events may have on the Company's and the Group's operations. Determining contingent liabilities and assets is a complex process that includes judgments regarding future events, laws, regulations, etc. Changes in crises or interpretations are likely to lead to an increase or decrease in the Company's contingent liabilities in the future. When additional information becomes available, the Group's Management reviews the facts, based on which it may also have to review its estimates (see Note 44).

4.SUMMARY OF SUBSTANTIAL AND OTHER ACCOUNTING POLICIES

4.1Substantial Accounting Policies

The key accounting policies adopted under the preparation of the accompanying consolidated and separate financial statements are as follows:

4.1.1Basis for consolidation

The accompanying consolidated financial statements include the financial statements of TERNA ENERGY and its subsidiaries as at 31/12/2024. The date of preparation of the Financial Statements of the subsidiaries is identical to that of the parent company.

Intra-group transactions and balances have been eliminated in the accompanying consolidated financial statements. Where required, the accounting policies of subsidiaries have been amended to ensure consistency with the accounting policies adopted by the Group. Note 5 provides a complete list of consolidated subsidiaries in line with the participating interest held by the Group.

Subsidiaries are consolidated from the date the Group acquires control over them and they cease to be consolidated at the date of termination of this control. Non-controlling interests constitute the component of equity of a subsidiary not directly or indirectly attributable to the parent. Losses relating to non-controlling interests (minority interests) of a subsidiary may exceed the rights of non-controlling interests in the subsidiary's equity. Gains or losses and each component of other comprehensive income are accounted for both by the owners of the parent and the non-controlling interests, even if, as a result, such non-controlling interests present deficit.

(a) Subsidiaries

Subsidiaries are all the companies, which the Parent has the power to control directly or indirectly through other subsidiaries and they are fully consolidated (full consolidation). The Company acquires and exercises control mainly through holding the majority of the voting rights of the subsidiaries. To define the control, the following conditions are examined, as recorded in IFRS 10:

1.The parent company has authority over the investee since it can direct the related (operational and financial) activities. This is achieved through appointing most of the members of the Board of Directors and the directors of the subsidiary by the Management of the parent.

2.The parent company holds rights with variable returns from its investment in the subsidiary. Other non-controlled investments are greatly dispersed and, therefore, cannot materially influence decision-making.

3.The parent company may exercise its authority over the subsidiary to influence the amount of its returns. This is the result of decision-making on subsidiary related matters through controlling the decision-making bodies (Board of Directors and Directors).

Changes in ownership interest in a subsidiary

TERNA ENERGY GROUP

Annual Financial Report for the year 2024

(Amounts in thousands of Euros unless mentioned otherwise)

146

In the case of changes in the parent’s ownership interest in a subsidiary, it is examined whether the changes result in a loss of control or not.

•Changes in a parent’s ownership interest in a subsidiary that do not result in a loss of control are accounted for as equity transactions (i.e. transactions with owners in their capacity as owners). In such circumstances, the carrying amounts of the controlling and non-controlling interests shall be adjusted to reflect the changes in their relative interests in the subsidiary. Any difference between the amount by which the non-controlling interests are adjusted and the fair value of the consideration paid or received shall be recognized directly in equity.

•In case the parents’ ownership interest changes in such a way that there is loss of control, then the parent shall record the necessary accounting entries and recognize the result from the sale (derecognition of the assets, goodwill and liabilities of the subsidiary as of the date of loss of control, derecognition of the book value of non-controlling interests, determination of the result from the sale).

•When determining the sale result, any amount previously recognized in other comprehensive income in respect of that company is accounted for using the same method as would be applied by the Group in the event of direct sale of its assets or liabilities. That is to say, the amounts previously recognized in other comprehensive income are reclassified to the income statement. Following loss of control of a subsidiary, any investment in the former subsidiary is recognized according to the provisions of IFRS 9.

Investments in subsidiaries in the separate Financial Statements

Investments of the parent in its consolidated subsidiaries are measured at acquisition cost, adjusted for changes in fair value of the subsidiaries’ contingent consideration less any accumulated impairment losses. The impairment test is carried out in accordance with the provisions of IAS 36.

(b) Joint arrangements

The Group applies IFRS 11 to all its joint arrangements. Under IFRS 11, joint arrangements are classified as joint operations or joint ventures, depending on the contractual rights and obligations of each investor. Jointly controlled entities are consolidated using the proportionate consolidation method (if it is a joint operation) or the equity method (if it is a joint venture).

Joint ventures: Joint ventures are accounted for using the equity method, under which participating interests in joint ventures are initially recognized at cost and subsequently readjusted in compliance with the Group's share of the profits (or losses) and other comprehensive income of the joint ventures. Under the joint venture model, joint venture schemes are the ones in which members have rights over the net assets of the investments and are liable up to the extent of their contribution to the capital of the company. If the Group's participating interest in joint venture losses exceeds the value of the participating interest, the Group discontinues recognizing further losses unless it has undertaken liabilities or has made payments on behalf of the joint venture. Allocation of operating results and other comprehensive results is proportional to the participating interest.

Unrealized gains on transactions between the Group and joint ventures are eliminated according to the Group's participating interest in joint ventures. Unrealized losses are also eliminated unless there is evidence of the transaction for impairment of the transferred asset.

Consolidation considers the percentage held by the Group, effective as at consolidation date. The structure of the business scheme is the key and determining factor in defining accounting treatment. The accounting policies of jointly controlled entities are consistent with those adopted and applied by the Group. The date

TERNA ENERGY GROUP

Annual Financial Report for the year 2024

(Amounts in thousands of Euros unless mentioned otherwise)

147

of preparation of the financial statements of jointly controlled entities coincides with that of the parent Company.

Investments in joint ventures in the separate Financial Statements

Investments of the parent in joint ventures are measured at acquisition cost less than any accumulated impairment losses. The impairment test is carried out in accordance with the provisions of IAS 36.

(c) Investments in jointly controlled operations in the separate Financial Statements

The parent company's participation in joint operations is proportionately incorporated in the Company's Financial Statements. Specifically, their assets and liabilities are included in the Company's financial statements on a proportionate basis.

Joint operations: Joint operations are accounted for using the proportional consolidation method. In particular, the Group recognizes in the consolidated financial statements: (i) its assets (including its share in any of its assets it holds jointly), (ii) its liabilities (including its share of any jointly held liabilities), (iii) it shares in the proceeds of the sale from disposal of joint venture, and (iv) its expenses (including its share in any jointly incurred expenses). Essentially, these are tax joint operations, which do not constitute a separate entity within the framework of the IFRS. Their assets and liabilities are incorporated according to the effective proportions in the financial statements of the Company.

(d) Associates

Associates are entities over which the Group exercises significant influence but does not exercise control. The Group's investments in associates are accounted for using the equity method. The assumptions used by the Group suggest that holding participating interest of between 20% and 50% of a company's voting rights implies a significant influence over the investee unless it can be clearly demonstrated that this is not the case. Investments in associates are initially recognized at acquisition cost and then consolidated using the equity method.

According to this method, investments in associates are recognized at acquisition cost less any changes in the Group's participating interest in Equity after the initial acquisition date, less any provisions for impairment of those participating interests’ value.

The consolidated statement of comprehensive income includes the proportion of the Group in the total income of associates. If the Group's participating interest in an Associate's loss exceeds the value of the participating interest, the Group discontinues recognizing further losses unless it has settled liabilities or made payments on the part of the associate and, in general, settled the payments arising from the shareholding. If the associate subsequently produces profits, the investor starts once again recognizing its share of profits only if its share of profits equals the share of losses it had not recognized.

Unrealized gains on transactions between the Group and associates are eliminated according to the Group's participating interest in associates. Unrealized losses are eliminated unless the transaction provides evidence of impairment of the transferred asset.

Accounting policies followed by associates do not differ from those used by the Group and the date of preparation of the financial statements of associates is the same as that of the parent.

Investments in associates in the separate Financial Statements

Investments of the parent in consolidated associates are measured at acquisition cost less any accumulated impairment losses. The impairment test is carried out in accordance with the provisions of IAS 36.

4.1.2Operating segments

The Board of Directors of the Company is the primary decision maker and reviews internal financial reporting in order to evaluate the performance of the Company and the Group and to make decisions on the allocation of resources. Management has determined areas of activity based on these internal reports.

The Group's activity is now focused on the construction, operation and exploitation of renewable energy plants such as wind farms, solar, hydro and biomass power plants (see in detail Note 1).

The main operating sectors of TERNA ENERGY in which the Group was active in the year 2024, based on the Group's internal reporting system, are divided between continuing operations in the field of renewable energy sources and discontinued operations in the areas of public works construction, concessions related to the operation of infrastructure and other projects of public interest (see Note 6).

4.1.3Intangible assets

The Group’s intangible assets pertain to forestry use licenses where wind farms have been located, acquired licenses for Wind Farms operations and acquired software.

Upon initial recognition, the intangible assets acquired separately are recorded at acquisition cost. Intangible assets acquired as part of business combinations are recognized at fair value on the acquisition date.

Following initial recognition, the intangible assets are measured at cost less accumulated amortization and any impairment loss. Amortization is recorded based on the straight-line method during the useful life of the said assets. All the Group's intangible assets have a definite useful life.

The period and method of amortization are reviewed at least at the end of every annual reporting period. Changes in the expected useful life of each intangible asset are accounted for as a change in accounting estimates.

Methods of amortization and useful lives of the Group's intangible assets can be summarized as follows:

Category	Methods of amortization	Useful life in years
Software	Straight-line	3
Generation and energy units installation and operation licenses	Straight-line	30
Forestry plots use rights	Straight-line	30

Gains or losses arising from the write-off due to disposal of an intangible asset are calculated as the difference between the net revenue from the disposal and the current value of the asset and are recognized in the profit or loss of the period.

a) Software

Maintenance of software programs is recognized as an expense when the expense is realized. On the contrary, the costs incurred for improving or prolonging the return of software programs beyond their initial technical specifications, or respectively the costs incurred for the modification of the software, are incorporated in the acquisition cost of the intangible asset, only if requirements of IAS 38 “Intangible assets” apply.

(b) Forestry plots use rights

The value of the land use rights of the forestry land where the Wind Farms are installed includes the acquisition cost of these items less the amount of accumulated amortization and any impairment of their value.

149

(c) Generation and energy units’ installation and operation licenses

Various types of licenses held by the Group enable it to construct energy units or generate the right to produce and sell energy. Effective market conditions provide the required indications regarding the recoverable amount of these licenses.

Upon acquisition, the Group recognizes these licenses as intangible assets at fair value and then measures them applying the cost model, according to which the asset is measured at cost (which is the acquisition fair value) less accumulated amortization and any accumulated provisions for impairment. Amortization is carried out on a straight-line basis over the useful life of those assets, which is 30 years for electricity generation from renewable energy sources. The amortization of the acquired licenses starts on the date of completion of the construction of each park and the date of electrification of the wind parks. Regarding the impairment tests, (see Note 4.1.5).

4.1.4Tangible Assets

Tangible fixed assets are recognized in the financial statements at acquisition values, less accumulated depreciation and any potential impairment losses. The acquisition cost includes all directly reimbursable costs incurred for the acquisition of these assets. Subsequent expenses are recorded as an increase in the book value of tangible assets or as a separate asset only to the extent that the said expenses increase the future economic benefits, expected to arise from the use of the fixed asset and that their cost can be measured reliably.

Tangible assets are written off when they are sold or withdrawn or when no further economic benefits are expected from their ongoing use. Gains and losses, arising from the write-off of tangible fixed assets, are included in the income statement for the year in which the asset is written off. Assets under construction include fixed assets under construction and are carried at cost. Assets under construction are not depreciated until the fixed asset is settled and put into operation.

Depreciation of tangible fixed assets (excluding land, which is not depreciated) is calculated based on the straight-line method over their estimated useful life as follows:

Property, plant and equipment	Useful life (in years)
Building and technical works	8 – 30
Machinery and technical installations	3 – 30
Vehicles	5 – 12
Furniture and fixtures	3 – 12

Useful life of tangible fixed assets is reviewed at least at the end of every reporting period.

When the book values of the tangible assets are higher than their recoverable value, then the difference (impairment) is recognized directly as an expense in the Income Statement. Upon sale of tangible assets, the differences between the received consideration and their book value are recognized as profits or losses in the Income Statement. Interest accrued on loans specifically or generally issued to finance the construction of tangible fixed assets is capitalized in the year when incurred, during the tangible asset’s construction period, provided that the recognition criteria are met (see Note 10).

Repairs and maintenance are recognized as expenses in the results of the financial year in which they are incurred.

4.1.5Impairment of non-current assets (intangible and tangible assets/investments in consolidated companies)

In respect of tangible and intangible assets subject to depreciation/ amortization, an impairment test is performed when events or changes in circumstances indicate that their carrying amount may no longer be recoverable. When the net book value of tangible and intangible assets exceeds their recoverable amount, then the excess amount relates to an impairment loss is recognized directly as an expense in the income statement. Respectively, financial assets that are subjected to impairment testing (if the relative indications are effective) are the assets measured at acquisition cost or under equity method (investments in subsidiaries and associates). The recoverable amount of investments in subsidiaries and associates is determined in the same way as that in respect of non-financial assets.

For the impairment test purposes, assets are grouped at the lowest level for which cash flows can be separately identified. The recoverable amount of an asset is the higher of the asset's fair value less costs to sell and value in use. For the purpose of calculating value in use, Management estimates the future cash flows from the asset or cash-generating unit and selects the appropriate discount rate in order to calculate the present value of future cash flows.

Impairment loss is recognized for the amount, by which the book value of an asset or a Cash Generating Unit exceeds their recoverable amount, which is the highest between fair value less sale costs and value in use.

In order to define value in use, the Management determines the estimated cash flows for every Cash Generating Unit, by defining a suitable discount rate in order to calculate the Present Value of these cash flows. Discount factors are determined individually for every Cash Generating Unit and reflect the corresponding risk data, determined by the Management for every one of them. Further assumptions are used which are prevailing in the energy market. Considering that the Group operates in the renewable energy sector, the Management considers that it is in the position to generate reliable projections for a period of more than five years, as the key assumptions of the estimates can be reliably predicted by using historical data.

The impairment losses of Cash Generating units, first reduce the book value of goodwill allocated to them. Residual impairment losses are charged pro rata to the other assets of the particular Cash Generating Unit. With the exception of goodwill, all assets are subsequently reviewed for indications that their previously recognized impairment loss is no longer effective.

An impairment loss is reversed if the recoverable amount of a Cash Generating unit exceeds its book value.

In such a case, the increased book value of the asset will not exceed the book value that would have been determined (net depreciation), if no impairment loss had been recognized, for the asset in the previous years.

4.1.6Financial instruments

4.1.6.1Recognition and derecognition

Financial assets and financial liabilities are recognized in the Statement of Financial Position if and only if the Group becomes a party to the financial instrument.

The Group ceases to recognize a financial asset if and only if the contractual rights to the cash flows of the financial asset expire or when the financial asset is transferred and all the risks and rewards, associated with the particular financial asset, are substantially transferred. A financial liability is derecognized from the Statement of Financial Position, if and only if, it is repaid - that is, when the commitment sets out in the contract is fulfilled, canceled or expires.

4.1.6.2Classification and initial recognition of financial assets

Except for trade receivables that do not include a significant finance item and are measured at the transaction price in accordance with IFRS 15, other financial assets are initially measured at fair value by adding the relevant transaction cost except in the case of financial assets measured at fair value through profit or loss.

Financial assets, except for those defined as effective hedging instruments, are classified into the following categories:

•Financial assets at amortized cost,

•Financial assets at fair value through profit and loss, and

•Financial assets at fair value through other comprehensive income without recycling cumulative profit and losses on derecognition (equity instruments).

Classification of every financial asset is defined according to:

•the Group's business model regarding management of financial assets, and

•the characteristics of their conventional cash flows.

All income and expenses related to financial assets recognized in the Statement of Comprehensive Income are included in the items "Other financial results", "Financial expenses" and "Financial income", except for the impairment of trade receivables included within operating results.

4.1.6.3Subsequent measurement of financial assets

Financial assets at amortized cost

A financial asset is measured at amortized cost when the following conditions are met:

I.financial asset management business model includes holding the asset for the purposes of collecting contractual cash flows,

II.contractual cash flows of the financial asset consist exclusively of repayment of capital and interest on the outstanding balance (“SPPI” criterion).

Following the initial recognition, these financial assets are measured at amortized cost using the effective interest method. In cases where the discount effect is not significant, the discount is omitted.

The amortized cost method includes non-derivative financial assets such as loans and receivables with fixed or pre-determined payments that are not traded on an active market, cash and cash equivalents, as well as trade and other receivables.

Financial assets measured at fair value through profit or loss

Financial assets at fair value through profit or loss include financial assets held for sale, financial assets designated at initial recognition at fair value through profit or loss, or financial assets that are required to be measured at fair value.

Financial assets are classified as held for sale if they are acquired for sale or repurchase in the foreseeable future. Derivatives, including embedded derivatives, are also classified as held for sale, unless defined as effective hedging instruments.

Financial assets with cash flows that are not only capital and interest payments are classified and measured at fair value through profit or loss, irrespective of the business model.

Financial assets classified at fair value through other comprehensive income (equity instruments)

In accordance with the relevant provisions of IFRS 9, at initial recognition, the Group may irrevocably choose to present in other results directly in equity the subsequent changes in the fair value of an equity instrument that is not held for sale.

TERNA ENERGY GROUP

Annual Financial Report for the year 2024

(Amounts in thousands of Euros unless mentioned otherwise)

152

Gains or losses from these financial assets are never recycled to the income statement. Dividends are recognized as other income in the income statement when the payment entitlement has been proved, unless the Group benefits from such income as a recovery of part of the cost of the financial asset - then such profit is recognized in the statement of comprehensive income. Equity instruments designated at fair value through other comprehensive income are not subject to an impairment test. This option is effective for every equity instrument separately.

The Group has chosen to classify investments in this category (see Note13).

4.1.6.4Impairment of financial assets

Adoption of IFRS 9 led to a change in the accounting treatment of impairment losses for financial assets, as it replaced the treatment effective under IAS 39 for recognition of realized losses with recognition of expected credit losses. Impairment is defined in IFRS 9 as an Expected Credit Loss (ECL), which is the difference between the contractual cash flows attributable to the holder of a particular financial asset and the cash flows expected to be recovered, i.e. cash deficit arising from default events, discounted approximately at the initial effective interest rate of the asset.

The Group and the Company recognize provisions for impairment for expected credit losses for all financial assets except those measured at fair value through profit or loss. The objective of provisions for impairment under IFRS 9 is to recognize the expected credit losses over the life of a financial instrument whose credit risk has increased since initial recognition, regardless of whether the assessment is made at a collective or individual level, using all the information that can be collected on the basis of both historical and present data, as well as data relating to reasonable future estimates of the financial position of customers and the economic environment.

To facilitate implementation of this approach, a distinction is made among:

•financial assets whose credit risk has not deteriorated significantly since initial recognition or which have a low credit risk at the reporting date (Stage 1) and for which the expected credit loss is recognized for the following 12 months,

•financial assets whose credit risk has deteriorated significantly since initial recognition, and which have no low credit risk (Stage 2). For these financial assets, the expected credit loss is recognized up to their maturity.

•financial assets for which there is objective evidence of impairment at the reporting date (Stage 3) and for which the expected credit loss is recognized up to maturity.

Trade receivables, other receivables and receivables from contracts with customers

The Group and the Company apply the simplified approach, stated in IFRS 9 to trade and other receivables as well as to receivables from construction contracts and receivables from leases, calculating the expected credit losses over the life of the above items. In this case, the expected credit losses represent the expected shortfalls in the contractual cash flows, considering the possibility of default at any point during the life of the financial instrument. While calculating the expected credit losses, the Group uses a provisioning matrix, grouping the above financial instruments based on the nature and maturity of the balances and taking into account available historical data in relation to the debtors, adjusted for future factors in relation to the debtors and the economic environment. Further analysis is presented in Notes 16, 17 and 18.

4.1.6.5Classification and measurement of financial liabilities

The Group's financial liabilities include mainly borrowings, suppliers and other liabilities, as well as derivative financial instruments. Financial liabilities are initially recognized at cost, which is the fair value of the

TERNA ENERGY GROUP

Annual Financial Report for the year 2024

(Amounts in thousands of Euros unless mentioned otherwise)

153

consideration received apart from borrowing costs. After initial recognition, financial liabilities are measured at amortized cost using the effective interest method, with the exception of derivatives that are subsequently measured at fair value with changes recognized in the income statement (except derivatives that operate as hedging instruments, see Note 4.1.6.6).

Financial liabilities are classified as short-term liabilities unless the Group unconditionally retains the right to defer settlement of the financial liability for at least 12 months after the reporting date of the financial statements.

In particular:

(i)Loan liabilities

The Group's loan liabilities are initially recognized at cost, which reflects the fair value of the receivable amounts less the relative costs directly attributable to them, where they are significant. After initial recognition, interest bearing loans are measured at amortized cost using the effective interest rate method. Amortized cost is calculated by taking into account issuing expenses and the difference between the initial amount and the maturity amount.

Gains and losses are recognized in the income statement when the liabilities are derecognized or impaired through the amortization procedures.

(ii)Trade and other liabilities

Balances of suppliers and other liabilities are initially recognized at their fair value and are subsequently measured at amortized cost using the effective interest rate method.

Trade and other short-term liabilities are not interest-bearing accounts and are usually settled on the basis of the agreed credits.

4.1.6.6Derivative financial instruments and hedge accounting

The Group's risk management policies are in line with the provisions of standards and hedge accounting is being applied.

In the context of risk management, the Group uses:

-derivative financial instruments for the exchange of interest rates to hedge the risks associated with the future fluctuation of variable loan interest rates,

-derivative financial instruments to hedge the risk of change in electricity prices (options, forward contracts for the sale of electricity) and

-derivative financial instruments to hedge the risks associated with the future fluctuation of variable income (Fixed for Floating swap contract).

These derivative financial instruments are initially recognized at their fair value at the date of the contract and are subsequently measured at their fair value. Changes in the fair value of financial derivative instruments are recognized at every reporting date either in the income statement or in other comprehensive income, depending on the extent, to which the derivative financial instrument meets the requirements of hedge accounting and, if so, according to the nature of the hedging object.

On the transaction date, the Group records the relationship between the hedging instrument and the hedging item, as well as the risk management objective and risk hedging transaction strategy. The Group also records both - when creating the hedging transaction and afterwards – the extent to which the instruments used in these changes are effective in offsetting fluctuations in the cash flows of hedging items.

Derivative financial instruments are measured at fair value at the reporting date and changes to be recognized in the income statement. The fair value of these derivatives is determined primarily on a market

TERNA ENERGY GROUP

Annual Financial Report for the year 2024

(Amounts in thousands of Euros unless mentioned otherwise)

154

value and is confirmed by the counterparty credit institutions. Exceptions are made regarding the derivatives that act as hedging instruments in cash flow hedges, for which special accounting is required. A hedging relationship is appropriate for hedge accounting when all the following criteria are met:

•the hedging relationship includes only eligible hedging instruments and eligible hedged items.

•at the inception of the hedging relationship there is a formal determination and documentation of the hedging relationship and the entity's risk management objective and its hedging strategy. The documentation includes determination of the hedging instrument, the hedged item, the nature of the hedged risk, and the manner in which the entity will assess whether the hedging relationship meets the effectiveness requirements (including an analysis of the sources of inefficiency of the hedge and how determination of the hedging factor).

•The hedging relationship covers all the following efficiency requirements: (a) there is an financial relationship between the hedged item and the hedging instrument, (b) the effect of the credit risk does not override the changes in value arising from this financial relationship, and (c) the hedging rate of the hedging relationship is the same resulting from the amount of hedged item actually hedged by the entity and the amount of the hedging instrument the entity actually uses to offset this amount of hedging item.

Future cash flows hedging

The component of changes in fair value that is attributable to effective risk hedging is recognized in equity. Any gain or loss arising from changes in fair value attributable to non-effective risk hedging is recognized directly in the statement of comprehensive income in the item "Profits from financial instruments measured at fair value". Cumulative amounts in equity are recycled through the Statement of Comprehensive Income to the income statement (from other comprehensive income to the income statement) in the periods in which the hedged item affects the income statement (when the projected hedged transaction is taking place). In forward interest rate swaps that include option (Interest rate CAP) the Group has elected to designate only the intrinsic value of the option as a hedge of the loan flows, recognizing the time value. The hedging cost is initially recognized in Other Comprehensive Income and is subsequently recycled from Other Comprehensive Income to Profit or Loss during the period of the hedge.

Hedge accounting is discontinued when the hedging instrument expires or is sold, terminated or exercised, or when the hedge no longer meets the hedge accounting criteria. The cumulative amount of gains or losses recognized directly in equity until that date remains in the reserves until the hedged item affects the Statement of Comprehensive Income. In the event that a hedged transaction is no longer expected to be realized, the net accumulated gains or losses recorded in the reserves are directly transferred to the Statement of Comprehensive Income.

4.1.6.7 Offsetting financial assets and financial liabilities.

Financial assets and financial liabilities are offset and the net amount is presented in the Statement of Financial Position only if there is the present legal right to offset the recognized amounts and the entity intends to settle them on a net basis or to require the asset and settle the liability simultaneously.

4.1.7Provisions, Contingent Assets and Liabilities

Provisions are recognized when the Group has present legal or imputed liabilities as a result of past events, their settlement is possible through resources’ outflow and the exact liability amount can be reliably estimated. The provisions are reviewed on the reporting date of the Financial Statements and adjusted in order to reflect the present value of the expense expected for the settlement of the liability. When the effect of the time value of money is significant, the provision is calculated as the present value of the expenses

TERNA ENERGY GROUP

Annual Financial Report for the year 2024

(Amounts in thousands of Euros unless mentioned otherwise)

155

expected to be incurred in order to settle this liability. If it is no longer probable that an outflow will be required in order to settle a liability for which a provision has been made, then it is reversed.

In cases where the outflow of economic resources due to current commitments is considered improbable or the provision amount cannot be reliably estimated, no liability is recognized in the financial statements. Contingent liabilities are not recognized in the financial statements but are disclosed unless the probability of an outflow of resources incorporating financial benefits is minimal. Potential inflows from economic benefits for the Group which do not meet the criteria of an asset are regarded as contingent assets and are disclosed when the inflow of the economic benefits is probable.

Provisions for rehabilitation of natural landscape

Concerning provisions for rehabilitation of natural landscapes, the Group recognizes the provisions made by the entities of the Group's energy sector for decommissioning wind turbines from Wind Farms and restoring the surrounding area. Decommissioning and rehabilitation provisions reflect the present value at the reporting date of the estimated cost less the estimated residual value of the recoverable materials. Provisions are reviewed at every reporting date of the Statement of Financial Position and are adjusted in order to reflect the present value of the expense, expected to be disbursed for settling the lability regarding decommissioning and rehabilitation. The related provision is recognized as an increase in the acquisition cost of wind turbines and is amortized on a straight-line basis over the 30-year term of the energy production contract.

Amortization -expense of the capitalized decommissioning and rehabilitation costs is included in the Statement of Comprehensive Income together with depreciation of Wind Farms. Any changes in estimates with respect to the estimated cost or the discount rate are added to or deducted from the cost of the asset, respectively. The effect of discounting the estimated cost is recognized in the income statement as an interest expense.

4.1.8Revenue

IFRS 15 established the core principle by applying the following steps for identifying revenue from contracts with customers:

1.Identify the contract(s) with a customer.

2.Identify the performance obligations in the contract.

3.Determine the transaction price.

4.Allocate the transaction price to the performance obligations in the contract.

5.Recognize revenue when (or as) the Group satisfies a performance obligation.

Revenue is recognized at the amount by which an entity expects to have in exchange for the transfer of the goods or services to a counterparty. When assigning a contract, the accounting treatment is also defined regarding the additional costs and the direct costs required to complete the contract. Revenue is defined as the amount that an entity expects to be entitled to in exchange for the goods or services it has transferred to a customer. If the promised consideration in a contract includes a variable amount, the entity estimates the consideration amount it would be entitled versus the transfer of the promised goods or services to customer. The consideration amount may vary due to discounts, price subsidies, refunds, credits, price reductions, incentives, additional performance benefits, sanctions or other similar items. The promised consideration may also change if the entity's entitlement to the consideration depends on the occurrence or non-occurrence of a future event. For example, a consideration amount will be variable if the product has

TERNA ENERGY GROUP

Annual Financial Report for the year 2024

(Amounts in thousands of Euros unless mentioned otherwise)

156

been sold with a refund option or if a fixed amount promise has been given as an additional performance benefit to achieve a specific milestone.

The volatility associated with the consideration promised by a customer may be expressly stated in the contract. An entity estimates the amount of the variable consideration using one of the following methods, whichever method it considers best suited to the amount of consideration to which it will be entitled:

(a) Estimated value - the estimated value is equal to the sum of the probability-weighted amounts in a range of possible consideration amounts. Estimated value is an appropriate estimate of the variable amount if the entity has a large number of contracts with similar characteristics.

b) Most probable amount - the most probable amount is the only most probable amount in a range of possible consideration amounts (i.e., the only likely outcome of the contract). The most probable amount is an appropriate estimate of the variable amount if the contract has only two possible outcomes (for example, the entity provides additional performance or not).

The Group and the Company recognize revenue when it satisfies the performance of the contractual obligation by transferring the goods or services on the basis of this obligation. Acquisition of control by the client occurs when it has the ability to direct the use and to derive virtually all the economic benefits from this good or service. Control is transferred over a period or at a specific time. Revenue from the sale of goods is recognized when the goods are transferred to the customer, usually upon delivery to the customer, and there is no obligation that could affect the acceptance of the good by the customer.

Commitments for implementation performed over time

The Group recognizes revenue for a performance obligation implemented over time only if it can reasonably measure its performance in full compliance with the obligation. The Group is not in a position to reasonably measure progress in meeting a performance obligation when it does not have the reliable information required to apply the appropriate method of measuring progress. In some cases (e.g. during the initial stages of a contract), the entity may not be able to reasonably measure the outcome of a performance obligation, but it at least expects to recover the costs incurred to meet it.

In such cases, an entity shall recognize revenue only to the extent of the cost incurred until it is able to reasonably measure the outcome of the implementation obligation.

Revenue from rendering services is recognized in the accounting period in which the services are provided and measured according to the nature of the services to be provided. The receivable from client is recognized when there is an unconditional right for the entity to receive the consideration for the contractual obligations performed to the client.

A contractual asset is recognized when the Group or the Company has settled its liabilities to the counterparty before the latter has paid or before the payment is due, for example when the goods or services are transferred to the customer prior to the right of the Group or the Company to issue an invoice. The contractual obligation is recognized when the Group or the Company receives a consideration from the counterparty as an advance or when it reserves the right to a consideration which is postponed before the performance of the contractual obligations and transfer of goods or services. The contractual obligation is derecognized when the contract obligations are met and the revenue is recorded in the Income Statement.

Commitments for implementation performed at a specific time

When a commitment for implementation is not met over time (as outlined above), then the entity enforces the implementation commitment at a particular time. In determining when the client acquires control of a

TERNA ENERGY GROUP

Annual Financial Report for the year 2024

(Amounts in thousands of Euros unless mentioned otherwise)

157

promised asset and the entity settles an implementation commitment, the entity examines the requirements for the acquisition control, as analytically recorded in IFRS 15.

The main categories of revenue recognized from implementation commitments fulfilled over time for the Group are as follows:

i) Revenue from contracts with customers related to construction operations

It relates to revenue from contracts with customers and results from implementation commitments that are fulfilled over time. For the purpose of complying with IFRS, the proceeds from the construction activity are accounted for progressively during construction, based on the input method of measurement in accordance with the provisions of IFRS 15 "Revenue from Contracts with Customers".

The input method recognizes revenue based on the entity's efforts or inflows towards fulfilling an implementation commitment (for example, the resources consumed, the hours worked, the costs incurred the time spent or the hours of operation of the machines consumed) in relation to the total expected inputs to fulfil this implementation commitment. The differences which arise as a consequence of the change in the contractual terms or claims are recognized in the financial accounts when the differences have been accepted by the counterparty or have been contractually agreed.

(ii)Sale of goods

Revenue from the sale of goods, after deduction of sales discounts, sales incentives and related VAT, is recognized when the significant risks and rewards of ownership of the goods are transferred to the buyer.

(iii)Revenue from sale of Electric Energy

It relates to revenue from contracts with customers and arises from implementation commitments that are fulfilled over time. Revenue from the Sale of Electric Energy is accounted for within the year it concerns. Under the preparation of the financial statements, the revenue from electricity purchased by DAPEEP or another customer not yet invoiced, is considered as revenue received but not invoiced.

Regarding the Group’s wind farms operating which sell electricity to energy market (Hellenic Energy Exchange) at market prices, revenue from the sale of electricity is recognized on the basis of the amount of electricity delivered at market prices for transactions, where all the revenue recognition criteria are met. In order to reduce its exposure to changes in energy prices in these markets, the Group uses the derivative instruments described in Note 4.1.6.6 above. The proceeds from the liquidation of these derivatives are included in the proceeds from the sale of electricity.

Green Certificates and Guarantees of Origin represent an economic benefit achieved by the operation of a wind farm. These Certificates are generated from the wind farms' electricity production and can be sold either through organized markets or directly to individual buyers under contracts. Proceeds from the sale of these Certificates are recognized as a component of revenue (Turnover) when they are sold.

(iv)Income from rentals

The income in question pertains to revenue from contracts with customers and arises from implementation commitments that are fulfilled over time. Income from rentals (operating leases) is recognized using the straight-line method according to the terms of the lease.

(v) Dividends

Dividends are accounted for when the right of recovery is finalized by the shareholders following the decision of the General Meeting of Shareholders.

(vi)Interests

Interest income is recognized on an accrual basis.

158

4.1.9Income tax

Income tax burden the fiscal year, consists of current tax, deferred tax and tax differences from previous years.

Current Tax

Current tax is calculated on the basis of the separate tax Statements of Financial Position of every company, included in the consolidated Financial Statements, according to the tax regulation effective in Greece or other tax frameworks under which the foreign subsidiaries operate. Expenditure on current income tax includes income tax that is based on the profits of each company as restated in its tax returns and provisions for additional taxes and is calculated according to the statutory or substantially statutory tax rates.

Deferred Income Tax

Deferred taxes are taxes or tax relief related to financial burdens or benefits accruing in the year but they have already been accounted for or to be accounted for by the tax authorities in different years. Deferred income tax is determined using the liability method, arising from the temporary differences between the carrying amount and the tax base of assets and liabilities. Deferred income tax is not accounted for if it arises from the initial recognition of an asset or liability in a transaction, other than a business combination that, when the transaction took place, did not affect either the accounting or the tax profit or loss.

Deferred income taxes are measured using the liability method in all temporary differences at the date of the financial statements between the tax base and the carrying amount of assets and liabilities. Deferred tax liabilities are recognized for all taxable temporary differences. Deferred tax assets are measured at every reporting date of the financial statements and are reduced to the extent that it is unlikely that there will be sufficient taxable profits against which part or all of the deferred income tax assets may be used.

Deferred tax assets and liabilities are measured at the tax rates expected to be effective for the year in which the asset will be incurred or the liability will be settled and are based on the tax rates (and tax laws) that are in effect or effectively in force as at the financial statements reporting date. In the event the time of reversing temporary differences cannot be clearly identified, the tax rate which is applicable, is the one of the next fiscal year of the Statement of Financial Position’s date.

Income tax related to items recognized in other comprehensive income is also recognized in other comprehensive income.

4.1.10Share capital, reserves and distribution of dividends

Common registered shares are recorded as equity. Costs, directly attributable to a component of equity net of tax effect, are monitored as a deduction to the Balance of Retained Earnings in equity. Otherwise, this amount is recognized as an expense in the period in question.

In cases when the Company or its subsidiaries acquire part of the Company's share capital (treasury shares), the amount paid, including any expense, net of tax, is deducted from equity until the shares are derecognized or sold. The number of treasury shares held by the Company does not reduce the number of shares in circulation but affects the number of shares included in the calculation of earnings per share.

In particular, the reserves are divided into:

Statutory reserves

In compliance with the Greek Commercial Law, companies shall transfer at least 5% of their annual net profits to a statutory reserve until such reserve equals 1/3 of the paid-up share capital. This reserve cannot be distributed during the Company's operations.

TERNA ENERGY GROUP

Annual Financial Report for the year 2024

(Amounts in thousands of Euros unless mentioned otherwise)

159

Development legislation reserves and other tax exempted reserves

These reserves refer to profits not taxed at the applicable tax rate in accordance with the applicable tax framework in Greece and include reserves arising from taxable profits and pertaining to the company’s participation in development laws. These reserves will be taxable at the tax rate applicable at the time of their distribution to the shareholders or their conversion into share capital under certain circumstances.

Cash flows risk hedging reserves

The risk hedge reserve is used to record profits or losses on derivative financial products, which can be classified as future cash flow hedges and are recognized in other comprehensive income.

Foreign currency translation differences from incorporation of foreign operations

Foreign exchange differences arising on foreign currency translation, during the consolidation of foreign subsidiaries, are recognized in other comprehensive income and accumulated in other reserves. The cumulative amount is transferred to the income statement of the year when the amounts were transferred.

Other reserves

Other reserves mainly include actuarial losses of pension schemes.

The category of other reserves comprises:

(1) Actuarial gains/(losses) from defined benefit pension schemes arising from (a) actual adjustments (the effect of differences between previous actuarial assumptions and those eventually occurring) and (b) changes in actuarial assumptions.

(2) Changes in fair value of investments classified as equity investments.

Treasury shares reserves

The Company has proceeded to successive acquisitions of treasury shares through implementing the approved share buy-back plan in accordance with article 49 of Law 4548/2018. The total value of these acquisitions is presented in reserves as a deduction from Equity.

Share-based payments program

IFRS 2 "Share-based payments" requires an expense to be recognized when the Company acquires goods and services in exchange for shares (equity settled transactions) or stock options or in exchange for other assets equivalent in value to a given number of shares or rights on shares (cash-settled transactions). The Company provides rights to free distribution of shares to its executives. The fair value of the services of the executives, who are granted the rights to free distribution of shares, is recognized in accordance with IFRS 2 as an expense in the statement of comprehensive income, with a corresponding increase in equity as " Reserves from Share based payments programs", during the period the services for which the rights are granted are, received. The total option expense or free distribution during the vesting period is calculated based on the fair value of the options granted on the grant date.

Dividends

Dividends distributed to the Company's shareholders are recognized in the financial statements as a liability in the period in which the distribution proposal of the Management is approved by the Annual General Meeting of the Shareholders. Also, at the same time, the financial statements reflect the effect of the disposal of the results approved by the General Meeting and the possible formation of reserves.

4.1.11Business combinations - Acquisition of entities that are not an 'enterprise' according to the definition in IFRS 3

In accordance with IFRS 3 "Business Combination", the Group determines whether a transaction or other event constitutes a business combination as defined in the Standard, i.e. whether the assets acquired and

TERNA ENERGY GROUP

Annual Financial Report for the year 2024

(Amounts in thousands of Euros unless mentioned otherwise)

160

liabilities assumed constitute a "business". In the event that the acquired assets are not a business, the Group shall account for the transaction or other event as an asset acquisition. According to IFRS 3, the term "business" identifies an integrated set of activities and assets, that is capable of being conducted and managed for the purpose of providing a return in the form of dividends, lower costs or other economic benefits directly to investors or to other owners, members or participants. The accounting treatment of a business combination does not apply to the acquisition of an asset (or group of assets) that does not constitute a "business".

In this context, in the case of acquisition of entities that do not meet the definition of "business" according to IFRS 3:

-The acquirer shall identify and recognize the individual identifiable assets acquired (including those assets that meet the definition of, and recognition criteria for intangible assets according to IAS 38) and liabilities assumed. In accordance with IFRS 3.2 (b), the cost of the group shall be allocated to the individual identifiable assets and liabilities on the basis of their relative fair values at the date of purchase.

-Goodwill or gain from a bargain purchase shall not be recognized from the transaction. The cost of the asset acquired (or group of assets) is allocated to the individual identifiable assets and liabilities based on their relative fair values at the date of purchase.

-In accordance with IAS 12.15, recognition of deferred tax is not permitted upon initial recognition of an asset or a liability in a transaction that is not a business combination. In this context, no deferred tax is recognized on the acquisition of assets.

-Costs associated with the acquisition of assets (e.g. fees of consultants, lawyers, accountants, appraisers and other professional and consulting fees) are recognized as an expense and are accounted for to profit or loss for in the period they are incurred.

-Any contingent consideration given by the Group is initially recognized at its fair value at the acquisition date. Changes in the fair value of the contingent consideration that meet the conditions for their classification as an asset or liability are recognized in the statement of comprehensive income.

4.2 Other Material Accounting Policies

The other material accounting policies that applied in the preparation of the accompanying Company and Consolidated Financial Statements are as follows:

4.2.1 Foreign currency translation

Functional and reporting currency

The consolidated financial statements are presented in Euro, which is the functional currency of the Group’s as well as the Group’s and Parent’s reporting currency.

Transactions and balances in Foreign Currency

Foreign currency transactions are converted into the functional currency by using the exchange rates applicable on the date when the transactions were performed. The monetary assets and liabilities which are denominated in foreign currency are converted into the Group’s functional currency on the Statement of Financial Position reporting date using the prevailing exchange rate on that day. Any gains or losses due to translation differences that result from the settlement of such transactions during the period, as well as from the conversion of monetary assets denominated in foreign currency based on the prevailing exchange rates on the Statement of Financial Position reporting date, are recognized in the Income Statement.

Non-monetary assets which are denominated in foreign currency and are measured at fair value are converted into the Group’s functional currency using the prevailing exchange rate on the date of their fair value measurement. The Foreign exchange translation differences from non-monetary items measured at

TERNA ENERGY GROUP

Annual Financial Report for the year 2024

(Amounts in thousands of Euros unless mentioned otherwise)

161

fair value are considered as part of the fair value and thus are recorded in the same account as the fair value differences.

Gains or losses arising from transactions in foreign currency as well as from the end of period valuation of monetary assets, denominated in foreign currency, which meet the criteria for cash flow hedges are recognized in other comprehensive income and cumulatively in equity.

Foreign operations

The functional currency of the Group’s foreign subsidiaries is the official currency of the country in which every subsidiary operates. For the preparation of consolidated financial statements, assets and liabilities of foreign subsidiaries, including goodwill and fair value adjustments due to business combinations, are translated into Euro at the exchange rates effective at the Statement of Financial Position reporting date. Revenue and expenses are translated into the presentation currency of the Group based on the average exchange rates for the reported period. Any differences arising from this procedure are debited/(credited) to foreign currency translation difference to Euro reserves from foreign operations, in equity, and recognized in other comprehensive income in the Statement of Comprehensive Income. Upon the disposal, write off or derecognition of a foreign subsidiary, the above reserves are transferred to profit or loss for the period.

4.2.2Borrowing costs

Borrowing costs that are directly attributable to acquisition, construction or production of qualifying assets, which will require considerable time until the assets are ready for the proposed use or disposal, are added to the acquisition cost of those assets until the assets are ready for the proposed use or disposal. In other cases, the borrowing costs burden gains or losses of the period when they incurred.

4.2.3Inventory

The Inventories include spare parts for machinery and raw and auxiliary materials for wind farms. Inventories are valued at the lower cost and net realizable value. The cost of raw materials, in-process and ready-made products is determined using the weighted average cost method. Appropriate provisions are made for obsolete inventories, if necessary. Write-downs of inventories to net realizable value and other losses on inventories shall be recognized in profit or loss in the period in which they occur.

4.2.4Cash and cash quivalent

Cash and cash equivalents include cash in hand, sight deposits, time deposits, bank overdrafts and other highly liquid investments that are directly convertible into particular amounts of cash equivalents which are subject to non-significant risk of change in value. The Group considers time deposits and other highly liquid investments with less than three months maturity as cash, as well as time deposits with over three months maturity for which it has the right to early liquidation without loss of capital.

For the purposes of preparing the Statements of Cash Flows, cash and cash equivalents consist of cash in hand, bank deposits as well as cash equivalents as defined above.

The Group’s restricted deposits, irrespective of the nature of the restrictions, are not included in cash and cash equivalents but are classified in the item "Prepayments and other receivables" (see Note 17.

4.2.5Employee benefits

Short-term benefits: Short-term employee benefits (except for termination of employment benefits) in cash and in kind are recognized as an expense when deemed accrued. Any unpaid amount is recorded as a liability, whereas in case the amount already paid exceeds the benefits’ amount, the entity identifies the excessive amount as an asset (prepaid expense) only to the extent that the prepayment shall lead to a future payments’ reduction or refund.

TERNA ENERGY GROUP

Annual Financial Report for the year 2024

(Amounts in thousands of Euros unless mentioned otherwise)

162

Retirement Benefits: Benefits following termination of employment include lump-sum severance grants, pensions and other benefits paid to employees after termination of employment in exchange for their service. The Group’s liabilities for retirement benefits cover both defined contribution plans and defined benefit plans. The defined contribution plan’s accrued cost is recognized as an expense in the period to which it relates.

Pension plans adopted by the Group are partly financed through payments to insurance companies or state social security funds.

a) Defined Contribution Plan

Defined contribution plans pertain to contribution payment to Social Security Organizations and therefore, the Group does not have any legal obligation in case the Fund is incapable of paying a pension to the insured person. The employer’s obligation is limited to paying the employer’s contributions to the Funds. The payable contribution by the Group in a defined contribution plan is identified as a liability after the deduction of the paid contribution, while accrued contributions are recognized as expenses in the income statement.

(b) Defined Benefit Plan (non-funded)

Under Laws 2112/20 and 4093/2012, the Company must pay compensation to its employees upon their dismissal or retirement. The amount of compensation paid depends on the years of service, the level of wages and the way of leaving service (dismissal or retirement). The establishment of the right to participate in these plans is carried out through the distribution of benefits in the last 16 years until the date of retirement of employees following the scale provided by Law 4093/2012.

The liability recognized in the Statement of Financial Position for defined benefit plans is the present value of the liability for the defined benefit less the plan assets’ fair value (reserves from payments to an insurance company), the changes deriving from any actuarial profit or loss and the previous service cost. The defined benefit commitment is calculated on an annual basis by an independent actuary through the use of the projected unit credit method. Based on all the above and given that there is no "significant" corporate bond market in Greece, the discount rate chosen is the iBoxx AA Corporate Overall EUR indices for the estimated duration of the plan at the valuation date. The value of the benchmark index as at 31/12/2024 was 2.93%, which is considered consistent with the principles of IAS 19, i.e. it is based on bonds respectively in terms of currency and estimated plan duration.

A defined benefit plan establishes, based on various parameters, such as age, years of service and salary, the specific obligations for payable benefits. Provisions for the period are included in the relative staff costs in the accompanying separate and consolidated Statement of Comprehensive Income and comprise the current and past service cost, the relative financial cost, the actuarial gains or losses and potentially any additional charges. Regarding unrecognized actuarial gains or losses, IAS 19 applies, which includes among other:

i)recognition of actuarial gains / losses in other comprehensive income and their permanent exclusion from the Income Statement,

ii)non-recognition of the expected returns on the plan investment in the Income Statement but recognition of the relative interest on net liability / (asset) of the benefits calculated based on the discount rate used to measure the defined benefit obligation,

iii)recognition of past service cost in the Income Statement at the earliest between the plan modification date or when the relative restructuring or terminal provision are recognized,

iv)other changes including new disclosures, such as quantitative sensitivity analysis.

4.2.6Leases

4.2.6.1 Recognition and initial measurement of the right-of-use asset

TERNA ENERGY GROUP

Annual Financial Report for the year 2024

(Amounts in thousands of Euros unless mentioned otherwise)

163

At the lease period commencement date, the Group recognizes a right-of-use asset and a lease liability, measuring the right-of-use asset at cost.

The cost of the right-of-use asset comprises:

•the amount of the initial measurement of the lease liability (see below),

•any lease payments made on or before the commencement date, less any lease incentives received,

•the initial direct costs incurred by the lessee, and

•an estimate of costs to be incurred by the Group in dismantling and removing the underlying asset, restoring the site on which it is located or restoring the underlying asset to the condition required by the terms and conditions of the lease. The Group undertakes the obligation for those costs either at the lease period commencement date or as a consequence of having used the leased asset during a particular period.

4.2.6.2 Initial measurement of the lease liability

At the lease period commencement date, the Group measures the lease liability at the present value of the lease payments that are not paid at that date. When the interest rate implicit in the lease can be readily determined, the lease payments shall be discounted using the interest rate implicit in the lease. If that rate cannot be readily determined, the Group shall use the Group’s incremental borrowing rate.

At the lease period commencement date, the lease payments included in the measurement of the lease liability comprise the following payments for the right-of-use asset during the lease term that are not paid at the lease commencement date:

i.fixed payments less any lease incentives receivable,

ii.any variable lease payments that depend on the future change in index or in interest rate, initially measured using the index or interest rate as at the lease period commencement date

iii.amounts expected to be payable by the Group under residual value guarantees,

iv.the exercise price of the call option if it is substantially certain that the Group will exercise the right, and

v.payments of penalties for terminating the lease, if the lease term reflects the Group exercising an option to terminate the lease.

4.2.6.3 Subsequent measurement

Subsequent measurement of the right-of-use asset

After the lease period commencement date, the Group measures the right-of-use asset applying a cost model.

The Group measures the right-of-use asset at cost:

-less any accumulated depreciation and any accumulated impairment losses, and

-adjusted for any subsequent measurement of the lease liability.

The Group applies the requirements set in IAS 16 regarding the depreciation of the right-of-use asset, which it reviews for potential impairment.

Subsequent measurement of the lease liability

After the lease period commencement date, the Group measures the lease liability, as follows:

i.increasing the carrying amount to reflect financial cost on the lease liability,

ii.reducing the carrying amount to reflect the lease payments made, and

iii. remeasuring the carrying amount to reflect any lease reassessment or modification.

TERNA ENERGY GROUP

Annual Financial Report for the year 2024

(Amounts in thousands of Euros unless mentioned otherwise)

164

The financial cost of a lease liability is allocated over the lease term in such a way that it results in a constant periodic interest rate on the remaining balance of the liability. After the lease period commencement date, the Group recognizes in profit or loss, (unless the costs are included in the carrying amount of another asset applying other applicable Standards), both:

i.financial cost of the lease liability, and

ii.variable lease payments not included in the measurement of the lease liability in the period in which the event or condition that triggers those payments occurs.

4.2.7Government grants

Government grants are recognized at fair value when there is reasonable assurance that the grant will be collected, and the Group will comply with all relevant conditions. Government grants related to the grants for tangible assets are recognized when there is reasonable assurance that the grant will be collected, and all relevant conditions will be met. These grants are recognized as deferred income and are transferred to the income statement during the period based on the expected useful life of the asset, for which the grant was received.

Government grants, relating to expenses, are recorded in transit accounts and recognized in the income statement over the period required so they are matched with the expenses they are intended to compensate.

4.2.8Earnings per share

Basic earnings per share are calculated dividing net earnings by the weighted average number of common shares outstanding during the period, excluding the weighted average number of the common shares acquired by the Group as treasury shares.

Earnings per share are calculated dividing the net profit attributable to shareholders by the weighted average number of shares outstanding during the year.

Diluted earnings per share are calculated when the Group has contingently issuable common shares, that is, common shares issuable for no cash or no cash after the fulfillment of certain conditions of a contingent share agreement.

As in the calculation of basic earnings per share, contingently issuable shares are treated as shares outstanding and are included in the calculation of diluted earnings per share if the necessary conditions are met (if the events have occurred). Contingent issuable shares are included from the beginning of the period (or from the date of the potential share agreement, if later). If the conditions are not met, the number of conditional issuable shares, included in the calculation of diluted earnings per share, is based on the number of shares that would have been issued if the end of the period/year had been the end of the term of the option.

6.SEGMENT REPORTING

Under the provisions of IFRS 8, an operating sector is a component of an entity: a) that engages in business activities from which it may earn revenues and incur expenses (including revenues and expenses relating to transactions with other components of the same entity), and, b) whose operating results are regularly reviewed by the entity’s chief operating decision maker to make decisions about resources to be allocated to the segment and assess its performance.

The term “chief operating decision maker” defines the function of the Group, which is to allocate resources to and assess the performance of the operating segments of an entity. For the application of IFRS 8, this function is assigned to the Board of Directors.

The Management separately monitors the operating results of the Group’s individual operating segments in order to make the necessary decisions, allocate the available resources and evaluate their performance.

On 28 November 2024, the acquisition of 70% of the shares of TERNA ENERGY S.A. from Abu Dhabi Future Energy Company PJSC - Masdar ("Masdar"), which were held by GEK TERA S.A. and other shareholders, was successfully completed.

In the context of the same agreement, was also took place the disposal to GEK TERNA Group of the construction activities of public works, infrastructure-related concessions and other projects of public interest and all research activities in the United States, the results of these activities are accounted for as results from discontinued operations as defined in IFRS 5 "Non-current Assets Held for Sale and Discontinued Operations" (see Management Report and Notes 5 and 7).

As a consequence of the above Agreement, TERNA ENERGY Group will permanently discontinue its activities in the operational areas of public works construction, the concessions related to the operation of infrastructure and other projects of public interest (such as the Single Automatic Collection System and the Municipal Waste Treatment Plant of the Regions of Epirus and Peloponnese) in exchange for their long-term exploitation by the provision of services to the public. Furthermore, the treatment also includes the research and development activities of renewable energy related projects that TERNA ENERGY ABETE Group had in the USA.

According to the above-mentioned, the main operating sectors of TERNA ENERGY in which the Group was active during the year 2024, based on the Group's internal reporting system, are divided between continuing operations in the field of renewable energy sources and discontinued operations in the areas of public works construction, concessions related to the operation of infrastructure and other projects of public interest.

The Group's performance by segment is presented in continuing operations and discontinued operations as follows:

7.BUSINESS COMBINATION AND ASSETS ACQUISITION

7.1 Business disposals and discontinued operations

In the context of the completion of the acquisition of 70% of the shares of TERNA ENERGY S.A. by Abu Dhabi Future Energy Company PJSC - Masdar ("Masdar") on 28 November 2024, it was also agreed that TERNA ENERGY S.A. will grant to GEK TERNA S.A. Group the construction activities of public works, infrastructure-related concessions and other projects of public interest as well as all exploration activities in the United States. The transaction price was considered reasonable based on the Auditor's Evaluation Report of 29.10.2024 pursuant to article 101 par. 1 of Law 4548/2018, as it was posted on the register of TERNA ENERGY S.A. in the General Commercial Register (GEMI).

11.2 Impairment test

In accordance with the applied accounting policies and in line with provisions of IAS 36, the Company performs an impairment test on the assets at the end of each annual reporting period if there is any indication of impairment. The test can be performed earlier if any evidence of impairment arises. The arising evaluation focuses on both - extrinsic and intrinsic factors.

Regarding the impairment test, every wind farm constitutes a Cash Generating Unit (CGU). The recoverable amounts of the above GTUs were determined using the value in use method. Value in use was calculated applying the discounted cash flow method, i.e. projections for cash flows, based on the Management calculations and projections until the end of the useful life of each wind farm.

Assumptions used to determine value in use

The key assumptions applied by Management relate to the determination of the present value of estimated future cash flows expected to be generated by each CGU (discounted cash flow method) and are as follows:

•Projected sales: Projected sales include management assumptions and estimates that have taken into account historical measurements of electricity generation and electricity sales prices.

•Pre – calculated EBITDA: Operating profit margins and EBITDA are calculated on the basis of the latest years’ actuarial data. For the projected period, EBITDA margin for RES is estimated fluctuate between 20% and 92% while for the biomass 14% and 15%.

•Discount rate from 5,9% up to7,6% per case (for Greece 5,87%, for Poland 7,62% and for Bulgaria 6,25%).

Based on the results of the impairment test as of December 31, 2024, the comparison of the recoverable amount from the investment costs of the subsidiaries' wind farms and their carrying amount did not result in the need for impairment. For TERNA ENERGY PAGION SA a reversal of impairment of € 23 thousand was performed. This company was ceded during the financial year as a consequence of its concession to the GEK TERNA Group of the activities of construction of public works, infrastructure-related concessions and other projects of public interest as well as all renewable energy research activities in the United States (see Management Report and Notes 5 and 7).

16.TRADE RECEIVABLES

The trade receivables of the Group and the Company in the accompanying separate and consolidated financial statements are analyzed as follows:

	GROUP		COMPANY

Total	27.248	78.825	84.097	114.889

The decrease in the Group's trade receivables is mainly due to the receipt of operating licenses for the Wind Farms complex in the Kafireas area, which results in the collection of receivables arising during the trial operation period of these new Wind Farms. Furthermore, the transfer of receivables arising from the business transformations and the transfer of discontinued operations contributed to the reduction of the Group’s and Company's trade receivables (see Notes 5 and 7).

The carrying amounts of customers represent their fair value.

The table below presents the total of trade receivables before impairment:

	GROUP		COMPANY
	31/12/2024	31/12/2023	31/12/2024	31/12/2023

Total prepayments and other receivables	118.823	131.748	22.753	31.960

The item "Prepayments to suppliers" of the Company is mainly due to advances related to the construction operation of the Group. It is noted that for the Group, the advances for new wind farms are advances for the acquisition of fixed assets. Therefore, at a consolidated level, they are classified under item "Property, plant and equipment" (see Note 10).

The change in “Receivables from VAT” is mainly due to the VAT (to be returned or to be offset) which derives from the construction of new projects by the Group’s subsidiaries.The decrease in the item "Prepaid expenses and other transitory assets accounts" of both the Group and the Company, is mainly due to discontinued operations of the Group which were disposed of.

The Group's long-term loans are related to the financing of its activities and mainly concern the financing of the construction and operation of Renewable Energy Sources facilities. The Group’s short‐term loans pertain to bank borrowings received at regular intervals which are renewed as needed. Collected amounts are mainly used to cover liquidity needs during the Wind Farms construction period of the Group’s energy sector.

All loans are recognized at amortized cost. The Group estimates that the fair value of the above loans does not significantly differ from their carrying amount. With regard to the fixed rate loans, whose carrying amount as at 31 December 2024 amounts to € 183,280 thousand, the Group estimates that the fair value is estimated at € 181,558 thousand.

To secure the Group loans, wind turbines of the Wind Farms are collateralized, as well as cash maintained in deposits for restricted use (see Note 19) while insurance contracts, receivables from the sale of electric energy to DAPEEP or/and HEDNO and debt securities (subsidiaries’ bonds owned by the parent company and subsidiaries’ shares) are pledged to banks. In the context of this form of financing, the Group’s companies maintain a series of restricted bank accounts, which serve the above liabilities. The submitted collaterals exceed the amount of the Group's loan liabilities.

On 31/12/2024, the total borrowings include amounts from non-recourse debt to the parent company in the amount of € 844.674 thousand, while the amounts of loans with the right of recourse to the parent company (recourse debt) amount to € 262.849 thousand.

The aforementioned financial instruments are measured at their fair value (see Note 41). During the financial year 2024, a total profit of € 1.189 thousand was recognized for the Group and the Company in the results

(Amounts in thousands of Euros unless mentioned otherwise)

201

of the fiscal year from changes in fair value, which is included in the item "Gains/Losses from financial instruments measured at fair value". Total changes in fair value recognized in other comprehensive income amounted to loss of € 1.526 thousand (2023: loss of € 4.106 thousand) for the Group of which € 833 thousand was recycled through the account “Financial Expenses”. For the company, the total charges in Fair Value recognized in Other Comprehensive Income amounted to a loss of € 1.140 thousand (2023: gain of € 12.260 thousand).

22.1Forward Interest Rate Swaps

In order to manage the interest rate risk that is exposed to, the Group has entered into forward interest rate swaps. The objective of interest rate swaps is to offset the risk of adverse future cash flows arising from interest on loan contracts entered into as a result of activities, in particular the electricity generation sector. Specifically, interest rate swaps relate to contracts whereby the variable interest rate on the loan is converted to fixed over the entire term of the loan, so that the Group is protected against any increase in interest rates. The fair value of these contracts was estimated by displaying the effective interest rate (euribor) curve as of 31/12/2024, throughout the time horizon of such contracts.

The fair value of these contracts as of 31/12/2024 amounted to a total net liability of € 3.384 (the total nominal value of the contracts amounting to € 480.208 thousand for Greece and Bulgaria). As of 31/12/2024, these derivatives met the requirements for cash flow hedging, in accordance with the provisions of IFRS 9 and from their measurement at fair values a loss of € (5.652) thousand (2023: loss € (16.626) thousand) was recognized in the item "Cash flow hedges" in Group’s Other Comprehensive Income Statement.

For the Company, the effect of the hedging of cash flows from the change in interest rates in the statement of other comprehensive income amounts to a loss of € 461 thousand (2023: loss € 256 thousand).

These financial liabilities are classified in the fair value hierarchy at level 2 (see Note 41).

In forward interest rate swaps that include option (Interest rate CAP) the Group has elected to designate only the intrinsic value of the option as a hedge of the loan flows, recognizing the time value of the options as hedging cost. The hedging cost is initially recognized in Other Comprehensive Income and is subsequently recycled from Other Comprehensive Income to Profit or Loss during the period of the hedge. For the year 2024, an amount of € 833 thousand was recycled to the profit or loss for the period, which is included in the “Financial Expenses” line item.

22.2Derivatives for hedging changes in energy market prices

Fixed for floating swap contracts

TERNA ENERGY Group has signed from the year 2021 contracts for the sale of electricity from Renewable Energy Sources (RES) with HERON ENERGY S.A. for 25 and 20 years in the framework of their cooperation in the "HERON EN.A" and "HERON EN.A BUSINESS" programs respectively. According to these agreements, TERNA ENERGY Group will receive fixed cash flows from the two programs, while it will pay the Proxy Market Revenues to HERON ENERGY (fixed for floating swap contract). Furthermore, TERNA ENERGY Group signed an 8-year PPA agreement with the possibility of extending it for a further 4 years, under which it will supply 100% green energy of 100 GWh/year to EYATH.

The fair value of this derivative on 31/12/2024 amounted to a total receivable of € 2.405 thousand. On 31/12/2024, this derivative met the requirements for cash flow hedging, in accordance with the provisions of IFRS 9. From its measurement at fair value a gain of € 4.126 thousand was recognized in the item "Cash

flow hedges" in the Other Comprehensive Income. For the effective part of this there was a valuation gain 1.189 thousand. This financial liability has been classified in the fair value hierarchy at level 3 (see Note 41).

23.PROVISION FOR STAFF INDEMNITIES

According to Greek labor law, each employee is entitled to a lump‐sum indemnity in case of dismissal or retirement. The amount of the indemnity depends on the length of service with the company and the employee’s wages the day he/she is dismissed or retires. Employees that resign or are justifiably dismissed are not entitled to such an indemnity. The indemnity payable in case of retirement in Greece is equal to 40% of the indemnity calculated in case of dismissal. According to the practices in the countries where the subsidiaries of the Group are operating in, staff indemnity programs are usually not funded.

The liabilities for staff indemnity liabilities were determined through an actuarial study. The following tables present an analysis of the net expenditure for the relevant provisions recorded in the consolidated Statement of Comprehensive Income for the fiscal year 2024 and the movement of the relevant provision accounts for staff indemnities presented in the attached consolidated Statement of financial position for the year ended on 31/12/2024.

In the above table, in addition to the analysis of the provisions based on the nature of the commitment, their analysis is also presented based on the expected schedule of the outflow of financial resources. In particular, provisions (except provisions for rehabilitation of natural landscape) are presented in total as long-term and are not recorded in discounted amounts as there is no accurate estimate of their payment time.

The Group’s companies of the energy sector are under obligation to proceed with environmental rehabilitation in locations, where they have installed electricity production units following the completion of the operations based on the effective licenses granted by the states where the installations are being implemented. The aforementioned provision of € 21.761 thousand (31/12/2023: € 18.219 thousand) reflects the expenses required for the removal of equipment and restoration of the area in which the equipment used to be installed, applying available technology and materials.

The other provisions of Group mainly concern provisions for pending legal litigations amounting to € 605 thousand (31/12/2023: € 473 thousand) and provisions for unaudited financial years amounting to € 757 thousand (31/12/2023: € 560 thousand) (see Note 44).

Statutory Reserves

In compliance with the Greek Commercial Law, companies shall transfer at least 5% of their annual net profits to a statutory reserve until such reserve equals 1/3 of the paid-up share capital. This reserve cannot be distributed but can be used for loss write off.

Treasury Shares

The Company during the period 01/01/2024 – 31/12/2024 did not purchase treasury shares. The total number of treasury shares held by the Company on 31/12/2024 was 653.046 with a total acquisition cost of € 9.317.349. These shares represented a percentage of 0,55% of the paid-up share capital of the Company.

Currency translation differences reserves

Under consolidation of foreign companies, foreign currency translation differences are recognized in other comprehensive income and cumulatively in foreign currency translation differences reserves from incorporating foreign operations. The cumulative amount is transferred to the income statement for the year when the investments are transferred.

Cash flows risk hedging reserves

The hedge reserve is used to record profit or losses on derivative financial instruments, which may be designated as cash flow hedges and recognized in other comprehensive income. When the transaction to which the hedge transaction relates affects the statement of comprehensive income, then the corresponding amounts are also transferred from the other comprehensive income to the statement of comprehensive income. During the year 2024, the Group recognized as an increase to these reserves, derivative losses after taxes amounting to € (550) thousand with the total of these reserves amounting on 31/12/2024 to a balance of € 674 thousand (see Note 22). Specifically, the interest rate hedging reserves include an amount of € 11.843 thousand and the related tax of € (2.608) thousand, which is related to forward interest rate swaps that contain an option (Interest rate CAP) for which the Group has chosen to designate only the intrinsic value of the option as a hedge of the loan cash flows, recognizing only the time value in the income statement through recycling (see Note 4.1.6.6.).

Proportional actuarial gains/(losses) reserves

Actuarial gains / (losses) from defined benefit pension plans arising from (a) experience adjustments (the result of differences between previous actuarial assumptions and those that eventually occurred) and (b) changes in actuarial assumptions.

Development and tax legislation reserves

These reserves refer to profits not taxed based on the applicable tax rate in accordance with the applicable tax framework. These reserves will be taxable at the tax rate applicable at the time of their distribution to the shareholders or their conversion into equity under certain circumstances.

The Group and the Company hold non-taxable reserves for the amount of € 45.846 thousand and € 6.155 thousand, respectively, which, if disposed or capitalized, will be taxed at the applicable tax rate and subject to the provisions of the relevant development laws.

Reserves from Share based payments programs

The Extraordinary General Meeting of 16.12.2020 of TERNA ENERGY SA approved the distribution of up to two million five hundred thousand (2.500.000) new shares to be issued with capitalization of reserves from the issue of premium shares to Executive Members of the Board of Directors and senior executives of the

The Board of Directors of the Company at its meeting of 19.03.2021, in implementation of the above decision of the Extraordinary General Meeting of Shareholders, accepted the recommendation of the Nominations and Remuneration Committee regarding the Revision of the Remuneration Policy, the Review of the Program Implementation Period (extension of the Program by one year, i.e. ending on 31.12.2024 – the extension of the duration of the program, in combination with its inclusion in the Remuneration Policy was approved by the Regular General Meeting of the Company's Shareholders on 23.06.2021), the conditions for the implementation of the Program, as well as the Criteria - Objectives of the Program (refer to the fulfillment of performance conditions not related to the market - e.g. project construction objectives, EBITDA, etc.), as well as regarding the Distribution of the shares per Criterion – Objective. At the same meeting, the Board of Directors reserved to decide further on the selection criteria of the beneficiaries, the distribution of the shares to the beneficiaries and on the vesting criteria per beneficiary at a new meeting after a new relevant proposal from the Nominations and Remuneration Committee.

At the meeting of January 26, 2022, the Board of Directors proceeded with the selection of the beneficiaries of the Share based payments programs as well as the allocation percentages in accordance with the recommendation of the Nominations and Remuneration Committee.

The Board of Directors of "TERNA ENERGY", by its resolutions of 18/01/2023 and 24/5/2023, approved the increase of the Company's Share Capital by the amount of Euro Six Hundred and Seventy-Five Thousand (€ 675.000,00) through the issuance of Two Million Two Hundred and Fifty Thousand (2.250. 000) of new ordinary registered shares with voting rights, with a nominal value of thirty-euro cents (€0,30) each, with capitalization of share premium reserves and their free distribution to Executive Members of the Board of Directors and senior management of the Company, in accordance with the approved Share Distribution Plan. This decision is related to the achievement of targets representing 90% of the total number of shares included in the Share Distribution Plan.

By the decision of the Board of Directors of "TERNA ENERGY", dated October 21, 2024, it was unanimously decided to increase the share capital of the Company by the amount of Euro Seventy Five Thousand (€ 75.000,00) by issuing two hundred and fifty thousand (250.000) of new ordinary registered shares with voting rights, with a nominal value of thirty euro cents (€ 0.30) each, with capitalization of share premium reserves, and their free distribution to Executive Members of the Board of Directors and senior management of the Company related to the achievement of targets representing 10% of the total number of shares included in the Share Distribution Plan.

With the distribution of the last part, the Share Distribution Plan was completed and the expense was recognized in the Administration Expenses of the year and more specifically in the category "Share option expenses" for the year 2024, with the latest amounting to € 2.313 thousand.

The total amount of the formed reserve of € 4.930 thousand was transferred to the account “Retained earnings”.

30.EARNINGS PER SHARE

Basic Earnings per Share were calculated by dividing the net earnings attributed to shareholders of the parent company by the weighted average number of outstanding shares as follows:

	GROUP
	31/12/2024	31/12/2023*
Net profit attributed to shareholders of the parent basic EPS (in thousand Euro)
- from continuing operations	70.426	56.680

- from continuing and discontinued operations	0,28186	0,51005

*The comparative figures of the Group and the Company for the financial year 2023 have been revised in order to include only continuing operations, as a consequence of the recognition of the Group's Construction and Concessions segments as discontinued operations, in accordance with the requirements of IFRS 5 "Non-current assets held for sale and discontinued operations" (see Notes 5 and 7).

31.INCOME TAX – DEFERRED TAXATION

The tax rate for legal entities in Greece in the year 2024, as for the year 2023, after the enactment of Law 4799/2021 which amended par. 1 of no. 58 of Law 4172/2013 is set at 22%. The effective tax rate differs from the nominal. The calculation of the effective tax rate is affected by several factors, the most important of which are non‐exemption of specific expenses, depreciation rates differences, arising between the fixed asset’s useful life and the rates defined under Law 4172/2013, and the ability of companies to generate tax‐exempted discounts and tax‐exempted reserves.

Effective tax rate	24,76%	21,24%	(304,42)%	(9,59)%

*The comparative figures of the Group and the Company for the financial year 2023 have been revised in order to include only continuing operations, as a consequence of the recognition of the Group's Construction and Concessions segments as discontinued operations, in accordance with the requirements of IFRS 5 "Non-current assets held for sale and discontinued operations" (see Notes 5 and 7).

The increase in effective tax rates is mainly due to the fact that the Group's accounting results include expenses such as the expense from the free distribution of shares which are not taxable. At the Company level, in addition to these expenses, the opposite effect is caused by the recognition of dividends from subsidiaries, which are not taxable. The income tax return is filed annually, but the profits or losses declared remain provisional until the tax authorities audit the taxpayer's books and records and issue a final audit report.

The Group annually estimates any contingent liabilities, expected to arise from the audit of past years, making relevant provisions where appropriate. The Group maintains provisions of € 757 for tax non-inspected financial years and the Management believes that apart from the provisions made, any potentially arising tax amounts will not have a significant impact on the Group's and Company’s equity, results, and cash flows. Information regarding tax non-inspected years is presented in Notes 5 and 44.1 to the Financial Statements.

The subsidiary EOLOS EAST SPZOO has been informed, following an audit carried out by the local tax authorities, of the existence of tax differences for the fiscal year 2019. The company exercised its rights of appeal and accordingly recognised a provision for tax differences for a total amount of € 396 thousand.

(b) Deferred Tax

213

Deferred tax assets and obligations are offset when there is an applicable legal right to offset current tax assets against current tax obligations and when deferred income taxes relate to the same tax authority.

The deferred income tax is calculated on all temporary tax differences between the book value and the tax value of assets and liabilities, using the expected effective tax rate at the time of maturity of the tax asset/ obligation:

Offset amounts as of 31/12/2024 and 31/12/2023 regarding the Group and the Company are analyzed as follows:

based payment program, the Management of "TERNA ENERGY S.A." informed the Investment Community that in order to implement the free share allocation program approved by the decision of the Extraordinary General Meeting of the Company's shareholders on December 16, 2020, and following their contribution to the achievement of the financial targets, the implementation of new projects and the increase of the Company's profitability, it has allocated to twenty-six (26) Directors a total of 250.000 New Shares, which resulted from increases in its share capital with capitalization of share premium reserves and represent 0,21% of the paid-up share capital. The shares were acquired through an over-the-counter transaction on 08/11/2024.

38.RISK MANAGEMENT POLICIES AND PROCEDURES

The Group is exposed to multiple financial risks such as market risk (fluctuations in exchange rates, interest rates, market prices, etc.), credit risk and liquidity risk. The Group periodically monitors and evaluates its exposure to the above risks, both separately and in combination, and uses financial instruments to hedge its exposure to specific categories of risks.

The assessment and management of the risks faced by the Group and the Company are carried out by the top management and the Board of Directors of the Company. The main objective is to monitor and assess all types of risks to which the Group and the Company are exposed through their business and investment activities.

The Group uses various financial instruments or implements specific strategies in order to limit its exposure to variability in investment values that may arise from market fluctuations, including changes in prevailing interest rates and exchange rates.

38.1 Foreign exchange risk

Foreign exchange risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in foreign exchange rates. This type of risk may arise, for the Group, from foreign currency transactions denominated in foreign currencies, with countries outside the Eurozone and countries that have not pegged their currency to the Euro. Transactions mainly relate to purchases of fixed assets and inventories, trade sales, investments in financial assets, borrowings, and net investments in foreign entities.

The Group operates, besides Greece, in Eastern Europe and therefore may be exposed to foreign exchange rate risk arising from the exchange rate between the euro and other currencies. This type of risk can only arise from commercial transactions in foreign currencies, from investments of financial assets in foreign currencies, as well as from net investments in foreign entities. In order to limit this risk, the Group utilises locally generated cash surpluses in local currency. During the operating phase, all related costs and revenues are incurred in local currency, eliminating any possibility of generating foreign exchange differences.

To mitigate this risk, the Group's financial management department systematically monitors exchange rate movements and ensures that they do not have a negative impact on the Group's cash resources.

With regard to the Company's transactions with foreign entities, these are generally with European Groups where the settlement currency is the euro and therefore no exchange rate risk arises.

The table below presents the sensitivity of the year’s result as well as of the other comprehensive income versus the exchange rate fluctuations through their effect on financial assets and liabilities. For the BGN currency we did not review the change as the currency has a fixed exchange rate against the Euro. For the other currencies we reviewed the sensitivity to a change of +/- 10%.

Effect on net profit after tax	1	(1)	325	(325)

To manage this category of risk, the Group’s Management and financial department makes sure that most of the receivables (income) and liabilities (expenses) are denominated in euro or in currencies with fixed exchange rate (e.g. Bulgarian lev (BGN)) with euro or in the same currency so that they could offset.

38.2 Interest rate risk

The policy of the Group is to minimize its exposure to the interest rate risk of long‐term financing. In this context, long-term loans received by the Group either bear a fixed interest rate or are hedged for almost the entire duration. In this context, on 31/12/2024, 16,55% of long-term loans received by the Group bear a fixed interest rate, 59,67% of long-term loans refer to floating-rate loans that have been hedged through derivatives with which future fixed rate payments are exchanged against floating rate collections, while 23,78% of long-term loans refer to floating rate loans on a case-by-case basis euribor or wibor.

The Group's short-term bank borrowings are all in euros with a variable interest rate linked to the euribor. Short-term loans are mainly taken as a bridge to cover temporary financing needs during the implementation - construction phase of the Group's investments (Wind Farms). These loans are repaid by taking out long-term loans upon completion of construction and commissioning of the wind farms. Consequently, the Group is exposed to interest rate risk arising from short-term borrowings and the portion of long-term borrowings that are at floating interest rates.

Interest rate risk sensitivity analysis

The following table presents sensitivity of the results for the year versus the Group’s short-term debt and deposits, given a reasonable change in variable interest rates amounting to +20% –20% (2023: +/-20% also). The changes in interest rates are expected to fluctuate on a normal basis in relation to current market conditions.

	2024		2023
Amounts in thousand €	20%	(20)%	20%	(20)%
Results for the year after tax – Group	(3.349)	3.349	(2.263)	2.263
Results for the year after tax – Company	(280)	280	(301)	301

The Group is not exposed to other interest rate risks.

38.3 Market Risk

The Group is not exposed to market risk for its financial assets, with the exception of the portfolio of listed securities. The Group has not taken specific hedges of this risk given that any impact is not expected to be significant.

38.4 Credit Risk

The Group continuously reviews its receivables and incorporates the resulting information into its credit control.

The majority of the energy segment receivables relates to the broader domestic (including ΕΝΕΧ, DAPEEP and DEDDIE) and foreign Public Sector.

TERNA ENERGY GROUP

Annual Financial Report for the year 2024

(Amounts in thousands of Euros unless mentioned otherwise)

231

The Group traditionally, due to the nature of its business, is not exposed to significant credit risk from trade receivables. In the past, there have been delays in collections from the DAPEEP, which have been significantly reduced with the implementation of Law 4254 /14 as well as the extraordinary levy imposed for the fiscal year 2020 to address the side effects of the coronavirus pandemic, on electricity producers from Renewable Energy Sources (RES) power plants, which have been put into normal or trial operation by 31 December 2015 (Government Gazette 245/09.12.2020). In other transactions with individuals, the Group operates with a view to limiting credit risk and securing its receivables.

The credit risk for cash and cash equivalents and other receivables is low, given that the counterparties are banks with a high-quality capital structure, the public sector or companies in the wider public sector or strong business groups.

Finally, the Group's management considers that all of the above financial assets which have arisen after making the necessary impairments are of high credit quality.

38.5 Liquidity Risk

The Group’s liquidity is considered satisfactory, as apart from the effective cash and cash equivalents, currently operating wind farms generate satisfactory cash flows on an on-going basis. In the year 2024net cash flows from continuing operating activities amounted to € 139 million versus € 147 million in 2023. The Group manages its liquidity needs by applying cautious cash flow planning, by carefully monitoring the balance of long‐term financial liabilities as well as by systematically managing the payments which take place daily. The liquidity needs are monitored at different time zones, on a daily and weekly basis, as well as based on a moving 30‐day period. The liquidity needs for the next 6 months, and the next year are defined monthly.

The Company maintains cash and cash equivalents in banks, in order to cover its liquidity needs for periods up to 30 days. The capital for mid‐term liquidity needs is released from the Company’s term deposits.

The maturity of financial liabilities as of December 31st, 2024 for the Group is analyzed as follows:

	31/12/2024
	Short-term	Long-term
	0 to 12 months	1 to 5 years	>5 years
Long‐term loans	99.800	475.728	491.390

38.6 Other risks and uncertainties

(a) Climate Change Risk and Fluctuations in wind and hydrological data

The Group's core business is closely linked to climatic conditions and in this context, management closely monitors developments and assesses the potential impact that climate change may have on the smooth operation of the facilities. From now on, calculation models should incorporate new factors allowing for the occurrence of potential events of force majeure, to examine in greater depth, the viability of any projected investment.

Regarding its activity in the energy sector, the Group remains exposed to the short-term fluctuations of wind and hydrological data, without affecting the long-term profitability of its projects, as the implementation of its investments is preceded by extensive studies on the long-term behavior of these factors.

(b) Political evolutions in the Group's area of operation

The military conflicts in the wider region of the Group's operations such as Ukraine and Middle East continue, and TERNA ENERGY Group continues to closely monitor the developments which have not had and are not expected to have a direct impact on the Group's figures and performance. As the majority of the A/Ps have a fixed sales price, the significant costs are depreciation of equipment and borrowing costs, which refer to fixed rate loans, the impact of which continues to be insignificant, and this is not expected to change in the foreseeable future.

Finally, due to the dynamic nature of these events, new risks may arise. Considering the current uncertainty about the wider economic climate, the Group's management is trying to assess any indirect consequences on the Group in a timely manner.

41.FAIR VALUE MEASUREMENT

Fair value measurements of financial assets

Financial assets and financial liabilities measured at fair value in the Group’s Statement of Financial Position are classified under the following in a three (3) level hierarchy in order to determine and disclose the fair value of financial instruments per valuation technique:

The Group has adopted the revision of IFRS 7 regarding the fair value hierarchy of the financial instruments at the following levels:

•Level 1: Fair value based on quoted (unadjusted) prices in active markets for comparable assets or liabilities.

•Level 2: Fair value, using valuation techniques for which all inputs that significantly affect the fair value, are based (either directly or indirectly) on observable market data.

•Level 3: Fair value, using valuation techniques, in which the data that significantly affects the fair value, are not based on observable market data.

The Group’s financial assets and financial liabilities measured at fair value as of 31/12/2024 and 31/12/2023 classified in the aforementioned levels of hierarchy, are as follows:

There were no changes in the valuation techniques applied by the Group within the current reporting period. Moreover, there were no transfers of amounts between the fair value hierarchy levels 1 and 2 during the 2024 and 2023.

The level 2 derivative financial instruments relate to forward rate swap contracts, while those of level 3 relate to fixed for floating swap contracts of the HERON EN.A, HERON EN.A BUSINESS and EYATH (see Note 22) and the contingent consideration from the acquisition of assets. To determine the fair value of the above financial instruments, the Group uses appropriate valuation techniques depending on the category of financial instrument. Regarding forward rate swap contracts, their fair value is measured by reference to market interest rate curves, through valuations by credit institutions and in combination with internal valuation using interest rate curves. With regard to the fixed floating swap contracts of the HERON EN.A and HERON EN.A BUSINESS and EYATH, their fair value is determined by using future market prices and discounting their estimated future value at present value.

The fair value of the contingent consideration from acquisition of assets (see Note 7), was determined based on the probability - weighted payout approach, at the acquisition date. The fair value of the liability for the contingent consideration is measured at each reference date and until the date of final measurement and payment.

The movement of financial instruments classified in Level 3 of the Group, for the years 2024 and 2023, are presented as follows:

42.CAPITAL MANAGEMENT POLICIES AND PROCEDURES

The aims of TERNA ENERGY Group regarding the Capital Management, are as follows:

•To ensure the ability of the Group to continue its activity (going concern).

•To secure a satisfactory return for its shareholders by pricing products and services according to their level of risk.

•to fulfill its contraction obligations in respect of specific debt agreements.

•to ensure it meets the minimum requirements set by legislation regarding undertaking of contractual constructions.

The Group defines the level of capital in proportion to the risk of its activities, it monitors the developments of the economic environment and their effect on the risk characteristics, and it manages the capital structure (relation of debt to equity) with the adjustment of the amount and maturity of debt, the issuance of new shares or the return of capital to shareholders, with the adjustment of the dividend and the sale of individual or a group of assets.

The Group finances the construction of Wind Farms and other projects through a combination of capital, bank borrowings and government grants. Therefore, the Group monitors Loan Liabilities to Total Employed Capital ratio. As Loan Liabilities is defined the total of Short-term Loans, Long-term Loans and Long-term loan liabilities payable next fiscal year. Total Employed Capital is defined as the total of equity capital, loan liabilities, lease liabilities, grants, reduced by the amount of cash and cash equivalents that are not subject to any restriction of use or commitment, in addition to the commitments associated with borrowing.

The ratio at the end of 2024 and 2023 was as follows:

The Group has settled all its material contractual obligations arising from loan agreements.

43.EFFECTIVE LIENS

In order to cover new projects’ financing needs, the Company and the Group issue notional collateral on its current assets as well as liens (usually in the form of mortgages) on its non-current assets as guarantees to the creditors. Additional information regarding such collaterals is presented in Notes 10 and 20.

44.CONTIGENT ASSETS AND LIABILITIES

44.1 Non audited Fiscal Years

The Group's tax liabilities are not definitive as there are unaudited tax years, which are disclosed in Note 5 of the Financial Statements. For unaudited tax years there is a risk that additional taxes and surcharges may be levied at the time they are reviewed and finalized. The Group annually assesses the contingent liabilities expected to arise from the audit of past years, making provisions where necessary. The Group has recognised provisions for unaudited tax years in the amount of € 757 thousand (31/12/2023: € 560 thousand). Management considers that, apart from the provisions recorded, any tax amounts that may arise will have no significant impact on the Group's and the Company's equity, results, and cash flows.

In accordance with the relevant tax provisions: a) of paragraph 1 of Article 84 of Law No. 2238/1994 (pending income tax cases), b) par. 1 of Article 57 of Law No. 57 of the Law Νo. 2859/2000 (pending VAT cases) and c) par. 5 of Article 9 of Law No. 2523/1997 (imposition of fines for income tax cases), the State's right to impose the tax for the years up to 2018 is time-barred until 31/12/2024, except for specific or extraordinary provisions that may provide for a longer limitation period and under the conditions set out therein.

In addition, in absence of an existing provision in the Code of Laws on Stamp Duties on the statute of limitations, the relevant claim of the State for the imposition of stamp duties is subject to the twenty-year statute of limitations according to article 249 of the Civil Code for cases that have been created until the 2013 financial year. From 1/1/2014, and after the entry into force of Law 4174/2013, the limitation period for the imposition of stamp duties is limited to 5 years, since the procedures for its imposition and collection are now included in the provisions of the Code of Tax Procedures.

•Tax Certificate-Tax Compliance Reports

For the fiscal years 2011 to 2023, the Group's companies operating in Greece and fulfilling the relevant criteria to be subject to tax audit by Certified Public Accountants received a Tax Compliance Report, in

TERNA ENERGY GROUP

Annual Financial Report for the year 2024

(Amounts in thousands of Euros unless mentioned otherwise)

238

accordance with par. 5 of article 82 of Law 2238/1994 and article 65A par. 1 of Law 4174/2013, without any significant differences. It should be noted that, according to Circular POL. 1006/2016, companies that have been subject to the aforementioned special tax audit are not exempted from the regular audit by the tax authorities. Furthermore, in accordance with the relevant legislation, for the fiscal years 2016 and onwards, the audit and the issuance of the Tax Certificate is applicable on an optional basis.

For the fiscal year 2024, for Group companies which operate in Greece and have been subject to the optional tax audit of the Certified Public Accountants, this audit is in progress and is expected to be completed after the publication of the accompanying Financial Statements. The Tax Certificate will be obtained upon its final submission by the Chartered Accountants to the tax authorities. On completion of these tax audits, the Management does not expect any substantial tax liabilities to arise other than those recorded and reflected in the financial statements of the Group and the Company.

It should be noted that, according to the provisions of POL 1192/2017, the right of the State to charge tax until the fiscal year 2018 has been limited, unless the special provisions of 10 years, 15 years and 20 years of limitation apply.

44.2 Commitments from construction contracts

The outstanding balance of the projects from construction contracts of the Group settles on 31/12/2024 at the amount of € 1.62 million (31/12/2023: € 12.6 million). It is noted that both the amount of the backlog as of 31 December 2024 and 31 December 2023 excludes the backlog of concession contracts as a consequence of the transfer of the construction and concessions activities to GEK TERNA Group (see Notes 5 and 7).

44.3 Significant litigations

The Company and its consolidated companies are involved (as defendant and plaintiff) in various legal cases in the context of their normal operation. The Group makes provisions in the financial statements related to the pending legal cases, when it is probable that an outflow of resources will be required to settle the outstanding obligation and the amount can be estimated reliably.

In this context, the Group has recognised provisions of € 605 thousand as at 31/12/2024 (31/12/2023: € 473 thousand). Management as well as the legal advisors estimate that, in addition to the above provisions, the pending cases are expected to be settled without any significant negative impact on the consolidated financial position of the Group or the Company, or on their results of operations beyond the provision for litigated cases already made.

In particular:

Contingent Liabilities

TERNA ENERGY S.A. and TERNA ENERGY AI GIORGIS S.A.

There is a legal lease dispute between an individual and the companies TERNA ENERGY S.A. and TERNA ENERGY AI GIORGIS S.A., regarding the lease of the island of Agios Georgios Attica from the other party to TERNA ENERGY. It is to be noted that on the island there is an installation of two wind farms of the subsidiary TERNA ENERGY AI GIORGIS S.A., with a total installed capacity of 69 MW.

The Lawsuit - Complaint dated 1/7/2019 brought at the Athens Court of First Instance by an individual against TERNA ENERGEKI A.B.E.T.E. and TERNA ENERGY AIGORGIS S.A., which was notified on 31-07-2019, requesting the restitution of the island of Agios Georgios, Attica, as an alleged leasehold property allegedly owned by the plaintiff, was heard on 6 September 2019. Thereupon, a decision No. 619/2020 was issued, which upheld the claim, ordered the restitution of the island of Agios Georgios to the plaintiff by TERNA ENERGY S.A. or anyone who derives rights from it, including TERNA ENERGY S.A. AI GIORGIS S.A. (it is understood that TERNA

239

ENERGY S.A. has transferred the Lease to that company, or has subleased a lease to it) and declared the decision provisionally enforceable. On 15.06.2020, TERNA ENERGY S.A. and TERNA ENERGY AI GIORGIS S.A. received a court order for voluntary compliance with the above decision, otherwise the court decision would be enforced. The companies TERNA ENERGY S.A. and TERNA ENERGY AI GIORGIS S.A. filed an application for suspension of execution of the above order, requesting an interim injunction, heard on 18 June 2020 and granted on 19 June 2020 until the hearing of the Application for Interim Measures on 28 July 2020, on which the decision no. 4555/2020 which granted the stay, and an appeal against decision No. 619/2020, on which was issued decision No. 548/2021 of the Athens Court of Appeal, which allowed the appeal, struck out the 619/2020 decision, retried the claim and dismissed it in its entirety. The opposing party filed a Petition for Appeal, which was heard by the Supreme Court of Greece and a 389/2022 decision was issued, which annulled the 548/2021 decision and referred the case back to the Court of Appeal for a new trial, which took place on June 7, 2022. In any case, the revocation of the 548/2021 decision revives the decision of the Athens Court of First Instance No. 4555/2020, by which the execution/executability of the 619/2020 decision has been suspended. The Athens Single Court of Appeal issued decision No 1937/2023, by which it formally and substantially accepts the appeal of 'TERNA ENERGY S.A.' and 'TERNA ENERGY I GIORGIS S.A.'. and dismisses the action brought by the individual. Against the decision of the Athens Court of Appeal No. 1937/2023, which dismissed the individual’s action, the individual filed an appeal dated 20.07.2023, the date of the hearing of which was initially set for 16.05.2025 and after a request for a hearing date by the individual, it was set for 19.04.2024. We presume the dismissal of the appeal.

The other party filed a lawsuit against TERNA ENERGY S.A. and TERNA ENERGY AI GIORGIS S.A., requesting the Application for Precautionary Measures, with a request for the termination of the Provisional Order as of 19.06.2020 of the Chairman of the Court of First Instance, granted in respect of as of 16.06.2020 Application for Suspension of Enforcement of the companies TERNA ENERGY S.A. and TERNA ENERGY AI GIORGIS S.A. or - alternatively - continuation of validity of the above Interim Order under the condition of payment to the applicant of the amount of € 8.931,67 per month as compensation for the use of its property. Both claims were heard and regarding those claims, no. 4555/2020 decision was issued, accepting the application for precautionary measures of TERNA ENERGY S.A. and TERNA ENERGY AI GIORGIS S.A., focusing on the issue of the installation of the latter, based on the protocols and not any type of lease relationship, speculating that this reason will be accepted in the Court of Appeal. A guarantee was ordered to be submitted in favor of the other party to the Deposits and Loans Fund, amounting to € 6.000,00. The Company has applied for the return of this letter of guarantee by way of an injunction.

The same opponent, succeeded in issuing against the Company no. 10898/2019 Payment Order of the Judge of the Single Member Court of First Instance of Athens, Chairman of the Court of First Instance, pursuant to which and from the order dated as at 04/12/2019 placed under a copy of the first executable inventory of the above payment order, the Company was ordered to pay to the other party a total amount of € 369.389,46 plus legal interest. The Company timely filed (GAK 108200/2019 and EAK 13627/2019) an Application for suspension of execution of the above payment order with a request for a temporary order, regarding which the temporary order as of 10.12.2019 of the Chairman of the Single Member Court of First Instance of Athens was issued, granting - temporarily and until the discussion of the above application on 11.03.2020 and given the course of the hearing - a suspension according to article 632 § 3 of the execution of the above payment order no. 10898/2019 setting the condition of the payment of guarantee by the Company amounting to € 50.000 within 15 working days from the publication of the temporary order. In this regard, a Letter of

Guarantee was issued, which was submitted to the Athens Court of First Instance, drafted under no. 519 / 31-12-2019 Guarantee Report. The application for precautionary measures was heard on 11.03.2020 and the validity of the effective interim injunction was extended until the issuance of the relative decision on it. No. 3804/2020 decision was issued, suspending the Payment Order until the issuance of a final decision regarding the case as of 19.12.2019, without the provision of a guarantee. The Company requested the restitution of this letter of guarantee by means of an injunction. The interim measures were discussed on 22.09.2023 and thereupon the decision No. 6053/25.10.2023 was issued which ordered the removal of the surety bond and ordered the individual to pay the Court costs of the Company.

Finally, the same opposing party brought an action before the Athens Court of First Instance against TERNA ENERGY A.B.E.T.E. and TERNA ENERGY A.I. GIORGIS S.A., which was notified on 20.07.2020, with which it waived its right to the 13.01.2020 of its action against the same opposing parties and on the other hand, it seeks compensation in the amount of € 235.179,65 due to tort, according to Article 914 of the Civil Code, consisting of the occupation of the island of Ag. George and the loss of income from the exploitation of the island by the individual. The action was judged at a formal trial on 23-3-2023 and a decision No. 6323/2023 was issued declaring the lawsuit inadmissible.

ENERGEIAKI DYSTION EVIAS S.A.

Individuals (plus 9) filed a Lawsuit against the Company in front of the Tamynea Magistrate Court for Disturbance of Law against the Company, on which Judgment No. 45/2022 was issued, which dismissed the lawsuit. Further, on 16.09.2022, the appeal of 2 of the aforesaid individuals against the Company and against Decision No. 45/2022 of the Tamynia Magistrate Court was notified, which was heard on 3/11/2023 and on which Decision No. 325/20.11.2023 was issued. Decision, which suspends the issuance of the decision until the Council of State issues a decision on the Petition for Annulment No. 1994/2021 filed by the opponents against the AEPO and the operating permission of the Company's park. It is noted that the Council of State, in its decision No 2379/2023, rejected the opponents' application for annulment.

Individuals have filed a lawsuit before the Chalkida Court of First Instance, which is directed against the Greek State and our Company, requesting that their ownership of the Company's property be recognized and that the Company be expelled from this property. The action was discussed and a decree no. 229/2022 Decision, which ordered the hearing to be reopened in order to produce the plaintiffs' submissions: (a) the decision of the Special Committee for the examination of the plaintiffs' objections to the forestry character of the disputed area and any corresponding corrections to the posted forestry map; and (b) the bulletin of the Government Journal with the publication of the forestry map for the disputed area described in the statement of reasons, as ratified by the Coordinator of the relevant Decentralized Administration. To date, there has been no development in the information requested. The Group's Legal Department presumes that this lawsuit will be dismissed.

ENERGEIAKI STYRON EVIAS S.A.

Two individuals filed a lawsuit against the Company in front of the Magistrate Court of Karystos, with the main request for the recognition of their status as tenants and owners of 3/4 of the first and 1/4 of the second property of the land district of the Municipality of Karystos. As this is a forest land, which is managed by the competent Forestry Department as public, the Company, which has been legally established on the disputed land by the Forestry Department of Karystos, has appealed to the Greek State to support it in this lawsuit, for which we believe that it will not succeed. The Greek State has intervened in the lawsuit in support of the Company. In this regard, a preliminary ruling was issued by the Karystos Magistrate's Court No. 11/2021,
