Α . Financial Highlights and Performance of financial year 2023

Despite the ongoing geopolitical uncertainties, high inflation and subsequent tight monetary policy, the Greek economy will maintain in 2023 a significant part of the growth momentum of the previous year but at a slower pace compared to the post-pandemic period of the previous year. As a result, according to ELSTAT, GDP in 2023 strengthened by 2.0% year-on-year (compared to 5.9% in 2022), well above the European average (estimated growth of 0.6%). It is worth noting that the growth rate exceeds the initial estimates for 2023, which set the bar at 1.7%, indicative of the resilience and dynamism of the economy. At the component level, GDP growth is supported by consumption (contributing around 70% of GDP) which strengthened by 1.8% due to an increase in disposable income following increases in wages/pensions and a reduction in unemployment. Still investment made a significant contribution to growth in 2023, with its growth (Gross Fixed Capital Formation) amounting to 4.0%. Finally, the growth rate of exports (+3.7% ) exceeded that of imports (2.1%) supported by the strong performance of tourism and leading to an improvement in the trade balance.

At the inflation forefront, the downward trend that started at the end of 2022 continued mainly as a consequence of the decline in international energy prices. Thus, annual inflation for 2023 stood at 3.5% based on ELSTAT data, compared with 9.6% for 2022.

In the budgetary sector, the country is expected to achieve a primary surplus of 1.1% of GDP in 2023 (compared to 0.1% in 2022 and initial estimates of 0.7% for 2023) following the robust GDP dynamics that led to both revenue growth and a reduction in expenditures related to supporting households and businesses during the 2022 energy crisis. For 2024, the target is for a primary surplus of 2.1% of GDP.

An important achievement for the Greek economy was the upgrade of the country's credit rating in 2023, which returned to investment grade after 13 years. In the second half of the year since Scope (BBB), DBRS (BBB low), S tandard and Poor’s (BBB-) and Fitch (BBB-) upgraded the Greek government's credit rating to investment grade. Consequently, Greek government bond yields as well as the spread against other government bonds have decreased (indicatively, the spread against the German bond decreased during 2023 by 84bps to 119bps).

For the coming years, however, the Greek economy is expected to maintain a growth rate higher than the European average, with the latest estimates from the Bank of Greece targeting GDP growth for 2024 of 2.3% (2.9% based on the government) and 2.5% for 2025 (vs. 0.8%-1.5% for the Eurozone respectively according to the ECB). The main drivers of the economy in the coming years will continue to be private consumption, investments, and exports, while the net contribution of the external sector will be marginally negative. The monetary policy is expected to continue to have a contractionary effect on economic activity, while investments will contribute positively to growth thanks to the resources of the Recovery and Resilience Mechanism.

Trends in the Energy Market in Greece during the year 2023

From the beginning of the year and the partial easing of geopolitical pressures, the energy market has entered a phase of normalization, with many parameters remaining volatile, however, affecting visibility in the medium term. This combined with lower demand, as a result of high prices, but also milder temperatures prevailing during the winter period, led to a continued deceleration in energy prices observed during the end of 2022 and a further decline during 2023. Indicatively, gas prices (TTF) fell from 2022 levels (average 133.7 EUR/MWh)

TERNA ENERGY FINANCE S.P.S.A.

Annual Financial Report for FY 2023

( Amounts in Euro thousand unless stated otherwise)

to 44.3 EUR/MWh for 2023. In a similar pattern, the electricity price on the wholesale market showed an average price of 132.2 EUR/MWh for the year compared to 306.6 EUR/MWh for 2022.

Electricity demand in 2023 recorded a 2.3% year-on-year decline, influenced mainly by the unseasonably high temperatures that prevailed in the first months of the year (and compared to particularly low temperatures for the corresponding months of 2022) and by the measures to limit consumption by households and businesses. It is notable that in the second half of the year demand increased by 4.0%.

The reduced demand, combined with increased production from RES, led to a drop in production from thermal stations in the interconnected system (19.2% decrease in lignite production, 18.5% decrease in gas production), while hydroelectric production, marginally increased by 1.1%. Renewable Energy production increased by 8.8% in line with the increase in installed capacity, while net imports also increased, covering 9.9% of total demand (compared to 6.8% for 2022). Overall, renewables covered 43.2% of demand (historical high) compared to 38.8% for the same period in 2022. It is worth noting that including generation from large hydropower plants, total green energy production in the country met 51.3% of demand in 2023 (vs. 46.7% for 2022).

In the renewable energy sector and more especially in wind power, the installed capacity of the market at the end of 2023 amounted to 5,226 MW showing an increase of 542.8 MW (+11.6%) compared to the end of 2022. The acceleration of growth is attributed to the gradual completion of large wind investments such as the Kafirea wind farm (327MW) by TERNA Energy. In terms of market shares, according to ELETAEN data, for 2023 in Greece, TERNA Energy held 19.7% of installed wind capacity, with the second and third producers holding 14.6% and 7.8% respectively.

According to the same source, at the end of 2023, over 850 MW of new wind farms were under construction or contracted in the Greek territory, of which over 300 MW are expected to be connected to the grid within the next 12 months. To these are added a further 400 MW that have been selected in tenders or have submitted performance guarantees but do not belong to any of the above categories. Thus, total wind capacity is expected to approach 6.5 GW within the next three years.

Regarding photovoltaics, according to the latest data for the whole country (HELAPCO-FEB 2024), 2023 was a record year with 1,574 MW of new photovoltaics added to the system compared to the end of 2022 (compared to 1,397 MW added for 2022), bringing the interconnected capacity to around 7,087 MW at the end of 2023. It is worth noting, however, that only 40.2% of new installations involved projects above 1.0 MW. According to market estimates, a similar number of new PV plants are expected to be interconnected in 2023 through 2024.

TERNA ENERGY GROUP

Throughout 2023, TERNA ENERGY Group continued 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. As part of this plan, the grid connection of the wind farm cluster at Kafirea with a total capacity of 327 MW was completed during the year, with the project now fully operational at the date of publication of the financial statements.

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 three years.

As of 31/12/2023, 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.

Basic Financial Figures:

The Company in 2023 realized Interest Income of € 5.369 thousand compared with € 5.352 thousand thousand of the previous year. The lack of volatility is due to the fact that there was no variation in the nominal value of the principal and the interest rate of the loan granted to the parent company TERNA ENERGY S.A. during the financial year 2023.

The results of the Company recorded a profit before taxes of € 709 thousand for the fiscal year 2023 compared to a profit of € 758 thousand in the previous year.

Finally, the liquidity ratio of the Company (Current Assets over Current Liabilities) settled at 8,37.

Regarding the allocation of the bond loan of TERNA ENERGY FINANCE SA (CBL) amounting to € 150,000 thousand, following the decision of 25 November 2022 of the Repetitive General Meeting of the Company’s bondholders, the manner of disposal of the funds raised for the period 22/10/2019 to 31/12/2022 is as follows:

It is noted that the disposal of all the funds raised was completed during the year 2022.

D. Risks and Uncertainties

Based on what has been extensively mentioned in the "Introduction" of the present report, the Company is operatively supported by its parent company TERNA ENERGY S.A., which fully influences the decisions, the Management and the operation of the Company and exercises control over them. In the event that TERNA ENERGY S.A. ceases to assist the Company in terms of management and operation or is unable to fulfill its contractual obligations to the Company, under the terms of the Intragroup Loan, this may have substantial negative consequences to the following: a) the ability of the Company to fulfill its obligations, mainly due to insufficient cash flows and revenues, b) the trading price of the Company Bonds on the Athens Exchange, c) the results, the financial position and the prospects of the Company.

Taking into account the above, the main risks and uncertainties in the business activities of the Company are directly related to those of the TERNA ENERGY Group (hereinafter "Group") and for this reason, the report on the Main Risks & Uncertainties of the Company should be combined with section E of the Annual Report of the Board of Directors of the parent company, sole shareholder and Guarantor, TERNA ENERGY S.A., with regard to the annual period ending on 31/12/2023, where a detailed reference is made to the risks of TERNA ENERGY S.A. The consolidated and separate financial statements of TERNA ENERGY S.A. for the year ended 31/12/2023 have been approved by the Board of Directors of the Company on 29/04/2024 and have been posted on the internet on its website www.terna-energy.com, as well as on ATHEX website.

In synopsis, we present the main risks and uncertainties in the activities of the TERNA ENERGY S.A. Group, as described in the published financial statements for the year ended 31/12/2023and which are summarized in the following:

Credit Risk

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

The energy sector accounts receivable are all related to the wider public sector both domestically (including ENEX, DAPEP, HEDNO, OASA, ASDA) and internationally, and the same applies to the concessions sector, as well as most of the construction sector receivables.

The Group has 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.

TERNA ENERGY FINANCE S.P.S.A.

Annual Financial Report for FY 2023

( Amounts in Euro thousand unless stated otherwise)

9

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 the above financial assets which have arisen after making the necessary impairments are of high credit quality.

Currency risk

The Group operates, besides Greece, also in Eastern Europe, therefore it is possible to be exposed to exchange rate risk that may arise from the exchange rate of the euro to 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 utilizes 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.

Interest rate risk

The Group's policy is to minimize exposure to interest rate risk in terms of long-term financing of its operations.

In the context of this policy, the long-term loans received by the Group either carry a fixed interest rate or are hedged for almost the entire duration of their term.

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 hedges of this risk given that any impact is not expected to be significant.

Liquidity risk analysis

The liquidity of the Group is considered satisfactory, as, in addition to the existing cash, the operating wind farms generate continuous, satisfactory cash flows.

Other risks and uncertainties

The construction sector of TERNA ENERGY is subject to significant fluctuations, both in terms of turnover and profitability of individual construction projects, as the construction activity, especially of specialized companies such as TERNA ENERGY, involves increased volatility mainly related to the ongoing renewal of the outstanding balance of construction contracts to third parties, which are mainly public sector entities.

(a) Special note to the war conflict in the region of Ukraine

The effects of this military conflict in Ukraine, which had a significant impact on the electricity market where the Group operates, seem to have stabilised. However, the risk is significant as long as there is no overall resolution of the conflict. In any case, considering the nature of the transactions carried out by the Group's companies, there was no direct impact on the Group's size and performance, and none is expected in the

TERNA ENERGY FINANCE S.P.S.A.

Annual Financial Report for FY 2023

( Amounts in Euro thousand unless stated otherwise)

10

future. Other risks such as the fluctuation of expected government revenues in the tourism sector, energy and grain price inflation and uncertainty in the development of foreign direct investment continue to be variables that may affect fiscal flexibility and the broader economic climate with unavoidable indirect consequences for the Group.

(b) 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 incorporate new factors allowing for the occurrence of potential events of force majeure, such as the current epidemic, in order 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, if the implementation of its investments is preceded by extensive studies involving long-term studies of the above factors.

Furthermore, the Company is directly exposed to multiple financial risks, such as credit risk and liquidity risk. The Company does not use derivative financial instruments to hedge its exposure to specific categories of risk.

The process followed is as follows:

(i) Assessment of risks related to the Company's activities and operations,

(ii) Designing the methodology and selecting appropriate financial products to mitigate the risks; and

(iii) Execution/implementation, in accordance with the procedure approved by the management, of the risk management process.

The Company's Financial Instruments consist of deposits with banks, receivables from bond loans granted to the parent company and liabilities from bond loans taken out.

Foreign exchange risk of the Company

The Company's functional currency is the Euro. The Company is not exposed to currency risk as all of its transactions are denominated in Euro.

Interest rate risk of the Company

The Company's policy is to minimise its exposure to interest rate cash flow risk in respect of long-term financing. The Company's borrowings relate to the 2019 CER (see Note 10), i.e. they are denominated in Euros and the interest rate is fixed. Therefore, the Company is not exposed to interest rate risk.

Credit risk of the Company

Credit risk is the risk when the counterparty to a financial instrument will cause a loss to the other party by failing to settle the related obligation.

E. Prospectives

The Company is a monetary capital, which is intended for the implementation of selected investments indicated by TERNA ENERGY S.A. (exclusive shareholder and Guarantor of the Bond Loan). As the Company has no other business activity, apart from its investment in the bonds of the Intragroup Loan issued by TERNA ENERGY S.A., is not active in any market and has no other assets.

Considering the above, the prospects of the Company should be read in conjunction with section D of the Annual Report of the Board of Directors of the parent company, sole shareholder and Guarantor, TERNA ENERGY S.A. of the annual period ending 31/12/2023, where a detailed reference is made to the prospects of the TERNA ENERGY S.A. The consolidated and separate financial statements of TERNA ENERGY S.A. for the year ended 31/12/2023 have been approved by the Board of Directors of the company on 29/04/2024 and have been posted on the internet on its website www.terna-energy.com, as well as on the Athens Exchange website.

Prospectives of TERNA ENERGY Group

The performance in 2023 and particularly in the first half of the year has been affected by the weak wind conditions observed in the country and in the Northern Hemisphere in general, in contrast to the highly enhanced conditions observed in the first half of last year. This fact is consistent with the stochasticity that governs production from wind farms and is taken into account in any forecasting model, without affecting the long-term performance of the projects, which, it should be remembered, have a 30-year lifespan.

With respect to the immediate periods following, TERNA Energy Group expects a significant strengthening of revenues and operating profitability subsequent to the commissioning of the Kafirea wind cluster before the end of the third quarter of 2023. The commissioning marks an increase in installed capacity of approximately 35% and is expected to have a corresponding impact on operating profitability (on an annualized basis). It is also worth mentioning that the excreta management project in the Peloponnese is now in full commercial operation and together with the other concessions/ PPP projects (waste management in Epirus, Electronic Ticket) will further enhance the Group's performance in the long term.

In the medium term, the Group continues to pursue its investment plan without interruption, having now under construction the large pumped-storage project in Amphilochia with a total investment of €650 million. The construction of new parks (mainly photovoltaic) in Greece is planned to start gradually from the end of this year and within 2024, while projects abroad continue to be considered on a case-by-case basis. Concurrently, the Group is advancing the procedures for the maturation of projects of various technologies (e.g. hydroelectric, storage, hybrid, etc.) in Greece that are expected to be able to gradually start construction from next year. Finally, emphasis is also given to new concessions/ PPP projects (waste management, digital transformation, etc.) that can further enhance the Group's revenues in the long term by generating synergies as well.

Considering the above and notwithstanding the continuous challenges and the always volatile conditions in the energy markets in Greece and abroad as the recent past has shown, Terna Energy Group is expected to continue to be a leading player. Recall the Group's long-term target to approach a portfolio of projects above 6.0 GW in operation before the end of the current decade.

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 Company uses Alternative Performance Measurement Indicators ("APMI") in decision-making regarding its financial and operational planning, as well as for the evaluation and publication of its performance. These APMIs serve to better understand the financial and operational results of the Company and its financial

TERNA ENERGY FINANCE S.P.S.A.

Annual Financial Report for FY 2023

( Amounts in Euro thousand unless stated otherwise)

12

position. Alternative Performance Measurement Indicators should always be considered in conjunction with the financial results prepared in accordance with IFRS and in no way replace them.

When describing the Company's performance, the following indicators are used:

“Net debt / (Surplus)” is a ratio by which the Company’s Management assesses each time the respective cash position. The ratio is defined as total long-term loan liabilities, short-term loan liabilities, long-term liabilities payable in the next fiscal year, less cash and cash equivalents.

“Loan Liabilities to Total Capital Employed” is a ratio with the Company’s Management assesses the Company’s financial leverage. As Loan Liabilities are defined Long - Term Loans and Long-term liabilities payable in the next fiscal year. The Total Capital Employed is defined as the sum of the total equity, plus the Net debt / (surplus).

“Gross Profit Margin” is an indicator by which the Company's Management evaluates its profitability and is defined as the percentage of net income / (expenses) from interest to interest income.

“EBIT (Earnings before Interest & Taxes) - Operating Profit before interest and taxes”: is an indicator by which the Company's Management assesses its operating performance. The figure is defined as: Net Profit / (loss) of the year less income tax.

“EBITDA (Earnings before Interest Taxes Depreciation & Amortization)”: It is an indicator by which the management evaluates the operational performance of the Company. The ratio adds to the operating profit before taxes and interest (EBIT), the total depreciation/amortization of tangible and intangible fixed assets and deducts the corresponding amortization of the fixed asset grants, if any.

The following table presents the Alternative Performance Measurement Indicators, which were measured in accordance with the Annual Financial Statements for the fiscal years 2023 and 2022:

6. Internal Audit and Risk Management

The Internal Audit System is defined as the set of rules and procedures applied by the Company aiming at the preventive and ex-post control of operations and procedures at all levels of its hierarchy and organizational structure, in order to ensure: the legality and security of management and transactions, the accuracy and reliability of published financial statements and any other financial information and announcement, as well as the efficiency of the Company's operating systems and operations.

The Board of Directors utilizes the internal audit system in order to protect the Company's assets, assess the emerging risks from all its operations and provide accurate and comprehensive information to shareholders on the actual situation and prospects of the Company, as well as on ways to address the identified risks.

For the implementation of the above, the Board of Directors determineσ the operating framework of internal audit, approves the procedures for conducting and evaluating its results and decides on its recruiting, in compliance with the requirements of the applicable legal and institutional framework as well as the Hellenic Corporate Governance Code. It establishes a special internal audit unit, which is independent, does not belong hierarchically to any other organizational unit and is supervised by the Company's Audit Committee.

With the contribution of the Audit Committee, it evaluates the adequacy and efficiency of the special internal audit unit and the degree of utilization of its reports by the Board of Directors for the continuous improvement of the Company's operation at all levels and the effective management of business risks. Also, the Audit Committee maintains direct and regular contact with the external auditors, in order to be systematically informed about the adequacy and reliability of the operation of the internal control and risk management systems, as well as the correctness and reliability of financial information.

The assessment and management of risks in the preparation of the Financial Statements for the Year 2023 is described in the relevant chapter of the Company's Annual Financial Report.

6.1 Risk Assessment Report – consequences of any findings – Management response.

The Company aims to contribute to the financing of its parent company TERNA ENERGY S.A. in order to achieve continuous sustainable growth and continuous expansion of its portfolio both in RES and in new areas of activity. Values, entrepreneurial spirit, integrity, personal participation and informed decision-making are the basic operating principles of the TERNA ENERGY S.A. Group and govern its business activity. In this context, the Company, in order to address risk factors from both the national and international business environment, has adopted procedures that regularly identify, evaluate and control the risks that arise.

The Risk Manager of the parent company recommends to the Board of Directors the Risk Management Strategy, the Approval of Risk Management Policies and Procedures, the Approval of the Annual Activity Plan of the Independent Risk Management Unit.

Risk Management in the preparation of Financial Statements

Specifically, there are three levels of control and risk management up to the preparation of the Company's individual Financial Statements. The financial statements are then forwarded to the Director of Financial and Administrative Services for review and approval.

TERNA ENERGY FINANCE S.P.S.A.

( Amounts in Euro thousand unless stated otherwise)

31

Subsequently, the Certified Auditors receive the data of the Financial Statements and proceed to their review.

It should be noted that SAP S/4HANA which is used across the Group automatically implements a series of controls and ensures that a wide range of risks are addressed.

The Audit Committee oversees the process of preparing the Company's financial statements and other financial reporting and examines their reliability. After examining and confirming the correctness of the process of preparing corporate and consolidated financial statements (interim and annual) following briefing by the Director of Financial and Administrative Divisions, the Committee proposes to the Board of Directors their approval and their signing and publication.

6.2 Annual review of corporate strategy, principal business risks and internal control systems

The annual review of the corporate strategy is made with reference to the update of business risks and the review of internal audit systems.

In 2023, the Audit Committee:

• Monitored the Internal Audit functions, the work of the Risk Manager and assessed the impact of risks on the design and operation of the Company.

• Monitored the adequacy and effectiveness of the Internal Audit System taking into account the content of the audit reports of the Internal Audit Unit.

• Was informed about any new risks that were included in the Risk Register within the financial year 2023.

• Monitored the Company's compliance procedures with the laws and regulations regulating its organization, operation and activities and taking into account the reports of the Compliance Unit. The Internal Audit Unit submitted to the Audit Committee, and through it to the Board of Directors, the Annual Audit Plan for 2024, which was prepared taking into account key corporate risks, prepared under §5, article 15 of Law 4706/2020.

7. Remuneration of BoD members

The Company does not pay remuneration to the members of the Board of Directors and also does not employ senior management.

8. Suitability Policy

The Company has a Suitability Policy for the Members of the Board of Directors, which was prepared by the Nominations and Remunerations 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 Extraordinary General Assembly of the Company's shareholders dated 16.07.2021 and entered into force on the date of its approval by the General Assembly. Individual amendments require re-approval by the Board of Directors, while revision of the Policy requires a Decision of the General Assembly. 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 is defined as a revision.

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 goals of the Company, with the aim of promoting the corporate interest.

The aim of the 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 protect and enhance

TERNA ENERGY FINANCE S.P.S.A.

Annual Financial Report for FY 2023

( Amounts in Euro thousand unless stated otherwise)

32

shareholder value, rather than a typical gathering of executives who manage corporate affairs without the capacity for constructive cooperation and development prospects.

The Policy takes into account best practices and is in line 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 effectiveness in the selection and during the term of office of the members of the BoD.

Furthermore, during the preparation of the Policy, the size, internal organization, risk ”appetite”, nature, scale and nature of the Company's activities were taken into account.

The guiding principles governing the policy are as follows:

• Compliance

• Transparency

• Proportionality

• Diversity

• Meritocracy

• Effectiveness

• Experience and historicity

9. Diversity policy

The Company has adopted and implements the diversity policy of TERNA ENERGY Group in order to promote an appropriate level of differentiation in the Board of Directors and a diverse group of members. The Policy is drafted with 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 diversity allows the Company to take advantage of market opportunities and effectively manage risks.

The Board can perform well if it consists of a wide range of members with diverse, but complementary skill or knowledge groups. 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 concentration of a wide range of qualifications and skills during the selection of Board members, 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 the sole criteria shoulde be those of individual suitability identified in the 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.

10. 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 procedure was drafted aiming at transparency and supervision of the Company's

TERNA ENERGY FINANCE S.P.S.A.

Annual Financial Report for FY 2023

( Amounts in Euro thousand unless stated otherwise)

33

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 definition 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.

11. Sustainable development policy

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 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.

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.

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.

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 into the corporate operation (Code of Ethics, Anti-Bribery Management System ISO 37001), and the regular training of human resources.

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 ensures the incorporation of 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 its 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 Directorate for Strategic Communication, Press Office, CSR and Sustainable Development has undertaken the task of coordination.

The CEO, through the direct reporting 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

(This report has been translated from Greek original version)

To the Shareholder of the company “TERNA ENERGY FINANCE SA”

Report on Financial Statements

Opinion

We have audited the accompanying financial statements of “TERNA ENERGY FINANCE SA” (“the Company”), which comprise of the statement of financial position as of December 31, 2023, statements of other comprehensive income, changes in equity and cash flows for the year then ended and notes to the financial statements, including material accounting policy information.

In our opinion, the accompanying financial statements present fairly, in all material respects, the financial position of the Company as of 31 December 2023, its financial performance and cash flows for the year then ended in accordance with International Financial Reporting Standards that have been adopted by the European Union.

Basis for opinion

We conducted our audit in accordance with International Standards on Auditing (ISAs) incorporated into the Greek Legislation. Our responsibilities under those standards are described in the Auditor’s Responsibilities for the Audit of the Financial Statements section of our report. We are independent of the Company within the entire course of our appointment in accordance with the International Ethics Standards Board for Accountants’ Code of Ethics for Professional Accountants (IESBA Code) incorporated into the Greek Legislation and ethical requirements relevant to the audit of financial statements in Greece and we have fulfilled our other ethical responsibilities in accordance with these requirements and the IESBA Code. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Key Audit Matters

Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the financial statements of the audited period. These matters, as well as the related risk of significant misstatements, were addressed in the

38

context of our audit of the financial statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters.

In our conclusion, there are no Key Audit Matters that should be disclosed in our Report.

Other information

Management is responsible for the other information. The other information is included in the Board of Director’s Report, the reference to which is made in the “Report on Other Legal and Regulatory Requirements” section of our Report and Representations of the Members of the Board of Directors, but does not include the financial statements and our auditor’s report thereon.

Our opinion on the financial statements does not cover the other information and we will not express any form of assurance conclusion thereon.

In connection with our audit of the financial statements, our responsibility is to read the other information identified above when it becomes available and, in doing so, consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the audit, or otherwise appears to be materially misstated. If, based on our audit, we conclude that there is a material misstatement therein, we are required to report that matter. No such issue has arisen.

Responsibilities of Management and Those Charged with Governance for the Financial Statements

Management is responsible for the preparation and fair presentation of the financial statements in accordance with International Financial Reporting Standards that have been adopted by the European Union and for such internal control as management determines is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the financial statements, management is responsible for assessing the Company’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 management’s intention is to proceed with liquidating the Company or discontinuing its operations or unless the management has no other realistic option but to proceed with those actions.

The Company’s Audit Committee (Article 44, Law 4449/2017) is responsible for overseeing the Company’s financial reporting process.

39

Auditor’s Responsibilities for the Audit of the Financial Statements

Our objectives are to obtain reasonable assurance about whether the financial statements as an aggregate, are free from material misstatement, whether due to fraud or error, and to issue an auditor’s 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, incorporated into the 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 affect the economic decisions of users taken on the basis of these financial statements.

As part of an audit in accordance with ISAs, incorporated into the 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 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 management.

• Conclude on the appropriateness of management’s 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 ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor’s report to the related disclosures in the 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 auditor’s report. However, future events or conditions may cause the Company and the Group to cease to continue as a going concern.

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

EXPLANATORY NOTES TO THE FINANCIAL STATEMENTS

1. GENERAL INFORMATION ABOUT THE COMPANY

"TERNA ENERGY FINANCE S.P.S.A." (henceforth "The Company") was incorporated following No. 19.634/ 14.10.2016 Notary Act, according to the provisions of Law 2190/1920 and was registered in the General Electronic Commercial Registry (GEMI) of the Athens Chamber of Commerce and Industry on 14/10/2016, under GEMI number 140274801000. It has its headquarters in Athens, 85 Mesogeion Ave, and its term is set for 110 years.

The Company’s operations focus on the following:

• investment and financing the operations of the Company and/or its affiliated companies and entities,

• intermediation in financing by third parties of the companies and businesses affiliated with the Company,

• provision of services and consultancy to companies and entities affiliated with the Company regarding the capital structure and in general their financing, and

• in general terms, undertaking any project, service and any activity or any other action which is relevant to the above scope of the Company’s operations or generally is performed in the context of that scope.

The Company is operationally supported by its sole shareholder TERNA ENERGY INDUSTRIAL COMMERCIAL TECHNICAL SOCIETE ANONYME (hereinafter referred to as "TERNA ENERGY S.A."), which controls decision making, operations and management of the Company to the utmost extent.

The accompanying Financial Statements as of December 31st, 2023, were approved by the Board of Directors on 29/04/2024 and are subject to the final approval of the General Meeting of the shareholders. They are available to the investor community at the Company’s offices (Athens, 85 Mesogeion Ave) and at the Company’s website.

The accompanying financial statements of the Company are consolidated under full consolidation method in the financial statements of TERNA ENERGY S.A., which is in Greece, listed at ATHEX, and whose participating interest in the Company on 31/12/2023 amounted to 100% ( 31/12/2022: 100%).

2. FRAMEWORK FOR THE PREPARATION OF THE FINANCIAL STATEMENTS

2.1 Basis for Financial Statements Presentation

The Company’s accompanying Financial Statements as of December 31st, 2023 covering the financial year starting on January 1st until December 31st 2023 have been prepared according to the International Financial Reporting Standards (IFRS), which were published by the International Accounting Standards Board (IASB) and according to their interpretations, which have been published by the International Financial Reporting Interpretations Committee (IFRIC) and have been adopted by the European Union until December 31st, 2023.

The Company applies all the International Accounting Standards (IAS), the International Financial Reporting Standards (IFRS) and their Interpretations that apply to its operations. The relevant

TERNA ENERGY FINANCE S.P.S.A.

Annual Financial Report for FY 2023

( Amounts in Euro thousand unless stated otherwise)

50

accounting policies, a synopsis of which is presented in following Note 2.6, have been consistently applied in all the presented periods.

Going Concern

On operational level, the Company is supported by TERNA ENERGY S.A. which affects to a significant extent the decisions, the management and the broader functioning of the Company exerting at the same time control over the above operations. The Company’s management estimates that the Company possesses sufficient resources, which ensure its operation as “Going Concern” in the foreseeable future.

The Management's decision to use the going concern principle is based on the estimates related to the potential impact of the military conflict raging in the wider Ukraine region. These factors have been considered by the Management for the preparation of the financial statements for the year ended 31/12/2023.

2.2 Basis of Measurement

The accompanying financial statements as of December 31st 2023, have been prepared according to the principle of historical cost.

2.3 Currency of Presentation

The currency of presentation is the Euro (meaning the currency of the company’s country) and all amounts are expressed in Euro thousand, unless stated otherwise.

2.4 Comparability

The comparative figures in the Financial Statements have not been restated.

2.5 Use of estimates

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. Opinions, assumptions and Management estimates affect the valuation of several asset and liability items, the amounts recognized during the financial year regarding specific income and expenses as well as the presented estimates on contingent liabilities.

The assumptions and estimates are assessed on a continuous basis according to historic experience and other factors, including expectations on future event outcomes that are considered as reasonable given the current conditions. The estimates and assumptions relate to the future and, consequently, the actual results may deviate from the accounting calculations.

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

2.6 New Standards, Interpretations and Amendments of Standards

The accounting principles applied for the preparation of the financial statements are the same as those applied for the preparation of the annual financial statements of the Company for FY ended as on December 31st, 2022, apart from the adoption of several new accounting standards, whose application was mandatory in the European Union for FYs beginning as on January 1st, 2023 (see. Notes 2.6.1 και 2.6.2).

2.6.1 New 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/ 2023.

Amendments to IAS 1 “Presentation of Financial Statements” (effective for annual periods starting on or after 01/01/2023)

In February 2021, the IASB issued narrow-scope amendments that pertain to accounting policy disclosures. The objective of these amendments is to improve accounting policy disclosures so that they provide more useful information to investors and other primary users of financial statements. More specifically, companies are required to disclose their material accounting policy information rather than their significant accounting policies. The Company has reviewed and applied the above amendment to its Financial Statements. The above have been adopted by the European Union with effective date of 01/01/2023.

Amendments to IAS 8 “Accounting Policies, Changes in Accounting Estimates and Errors: Definition of Accounting Estimates” (effective for annual periods starting on or after 01/01/2023)

In February 2021, the IASB issued narrow-scope amendments that clarify how companies should distinguish changes in accounting policies from changes in accounting estimates. That distinction is important because changes in accounting estimates are applied prospectively only to future transactions and other future events, but changes in accounting policies are generally also applied retrospectively to past transactions and other past events. The amendments do not affect the consolidated and separate Financial Statements. The above have been adopted by the European Union with effective date of 01/01/2023.

Amendments to IAS 12 “Income Taxes: Deferred Tax related to Assets and Liabilities arising from a Single Transaction” (effective for annual periods starting on or after 01/01/2023)

In May 2021, the IASB issued targeted amendments to IAS 12 to specify how companies should account for deferred tax on transactions such as leases and decommissioning obligations – transactions for which companies recognise both an asset and a liability. In specified circumstances, companies are exempt from recognising deferred tax when they recognise assets or liabilities for the first time. The amendments clarify that the exemption does not apply and that companies are required to recognise deferred tax on such transactions. The amendments do not affect the consolidated and separate Financial Statements. The above have been adopted by the European Union with effective date of 01/01/2023.

Amendments to IAS 12 “Income taxes”: International Tax Reform – Pillar Two Model Rules (effective immediately and for annual periods starting on or after 01/01/2023)

In May 2023, the International Accounting Standards Board (IASB) issued amendments to IAS 12 “Income Taxes”: International Tax Reform—Pillar Two Model Rules. The amendments introduced a) a temporary exception to the requirements to recognise and disclose information about deferred tax assets and liabilities related to Pillar Two income taxes and b) targeted disclosure requirements for

TERNA ENERGY FINANCE S.P.S.A.

Annual Financial Report for FY 2023

( Amounts in Euro thousand unless stated otherwise)

52

affected entities. Companies may apply the temperorary exception immediately, but disclosure requirements are required for annual periods commencing on or after 1 January 2023. The amendments do not affect the consolidated and separate Financial Statements. The above have been adopted by the European Union with effective date of 01/01/2023.

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 Group/ Company will examine the impact of the above on its Financial Statements, though it is not expected to have any. The above have been adopted by the European Union with an effective date of 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)

In January 2020, the IASB issued amendments to IAS 1 that affect requirements for the presentation of liabilities. Specifically, they clarify one of the criteria for classifying a liability as non-current, the requirement for an entity to have the right to defer settlement of the liability for at least 12 months after the reporting period. The amendments include: (a) specifying that an entity’s right to defer settlement must exist at the end of the reporting period; (b) clarifying that classification is unaffected by management’s intentions or expectations about whether the entity will exercise its right to defer settlement; (c) clarifying how lending conditions affect classification; and (d) clarifying requirements for classifying liabilities an entity will or may settle by issuing its own equity instruments. Furthermore, in July 2020, the IASB issued an amendment to defer by one year the effective date of the initially issued amendment to IAS 1, in response to the Covid-19 pandemic. However, in October 2022, the IASB issued an additional amendment that aim to improve the information companies provide about long-term debt with covenants. IAS 1 requires a company to classify debt as non-current only if the company can avoid settling the debt in the 12 months after the reporting date. However, a company’s ability to do so is often subject to complying with covenants. The amendments to IAS 1 specify that covenants to be complied with after the reporting date do not affect the classification of debt as current or non-current at the reporting date. Instead, 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 or after 1 January 2024, with early adoption permitted. The Group will examine the impact of the above on its Financial Statements, though it is not expected to have any. The above have been adopted by the European Union with an effective date of 01/01/2024.

2.6.2 New 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.

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 IASB issued Supplier Finance Arrangements to 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 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 Group/ Company will examine the impact of the above on its Financial Statements, though it is not expected to have any. The above have not been adopted by the European Union.

Amendments to IAS 21 “The Effects of Changes in Foreign Exchange Rates: Lack of Exchangeability (effective for annual periods starting on or after 01/01/2025)

In August 2023, the International Accounting Standards Board (IASB) issued amendments to IAS 21 The Effects of Changes in Foreign Exchange Rates that require entities to provide more useful information in their financial statements when a currency cannot be exchanged into another currency. The amendments introduce a definition of currency exchangeability and the process by which an entity should assess this exchangeability. In addition, the amendments provide guidance on how an entity should estimate a spot exchange rate in cases where a currency is not exchangeable and require additional disclosures in cases where an entity has estimated a spot exchange rate due to a lack of exchangeability. The amendments to IAS 21 are effective for accounting periods on or after 1 January 2025. The Group/ Company will examine the impact of the above on its Financial Statements, though it is not expected to have any. The above have not been adopted by the European Union.

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, contingent receivables, and liabilities disclosures as well as revenue and expenses during the presented periods.

In particular, 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 Company and requires the most

TERNA ENERGY FINANCE S.P.S.A.

Annual Financial Report for FY 2023

( Amounts in Euro thousand unless stated otherwise)

54

difficult, subjective, or complex judgments of the Management. Estimates and judgments of the Management are based on past 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 development could affect the financial statements items in the upcoming 12 months are the following:

Provision for Income Tax

The 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. The final settlement of the income tax might deviate from the respective amounts that have been recognized in the financial statements (further information is provided in Note 16).

4. SUMMARY OF MATERIAL AND OTHER ACCOUNTING POLICIES

4.1 Material Accounting Policies

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

4.1.1 Financial instruments

4.1.1.1 Recognition and derecognition

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

The Entity 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.

4.1.1.2 Classification 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 & loss, and

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

During the periods presented, the Company has not classified any financial assets in the category "financial assets at fair value through profit or loss" or in the category "financial assets at fair value through other comprehensive income".

( Amounts in Euro thousand unless stated otherwise)

55

Classification of every financial asset is defined according to: the Entity's business model regarding management of financial assets, and the characteristics of their conventional cash flows.

4.1.1.3 Subsequent 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.

As at 31/12/2023, the Company does not hold any financial assets classified in the other categories defined by IFRS 9.

4.1.1.4 Impairment 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

• financial assets whose credit risk has deteriorated significantly since initial recognition, and which have no low credit risk (Stage 2).

• Stage 3 refers to financial assets for which there is objective evidence of impairment at the reporting date.

( Amounts in Euro thousand unless stated otherwise)

56

For financial assets included in Stage 1, expected credit losses are recognised for the period of the next 12 months, while for those included in Stage 2 or Stage 3, expected credit losses are recognised over the entire life of the financial asset.

Expected credit losses are based on the difference between the contractual cash flows and the cash flows the Company expects to receive. The difference is discounted using an estimate of the initial effective interest rate of the financial asset.

4.1.1.5 Classification 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 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.

(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

The 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.

4.1.1.6 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.

4.1.2 Income tax

The income tax expense for the year consists of current taxes, deferred taxes and tax audit differences from previous years.

Current income tax

Current tax is calculated on the basis of the Tax Statements of Financial Position, in accordance with the tax laws applicable in Greece. Current income tax expense includes income tax based on the

TERNA ENERGY FINANCE S.P.S.A.

Annual Financial Report for FY 2023

( Amounts in Euro thousand unless stated otherwise)

57

Company's earnings as restated in its tax returns and provisions for additional taxes, and is calculated in accordance with statutory or substantively enacted tax rates.

Deferred income tax

Deferred taxes are taxes or tax credits related to economic charges or benefits that arise in the financial year but have been or will be levied by the tax authorities in different years. Deferred income tax is determined using the liability method arising from temporary differences between the carrying amounts and tax bases of assets and liabilities.

Deferred income tax is calculated using the liability method on 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 recognised for all taxable temporary differences.

Deferred tax assets are assessed at each Financial Statements date and reduced to the extent that it is not considered probable that sufficient taxable profit will be available against which some or all of the deferred income tax assets can be utilised.

Deferred tax assets and liabilities are measured using the tax rates expected to be in effect in the year in which the asset will be realized or the liability settled, and are based on tax rates (and tax laws) that are enacted or substantively enacted at the reporting date of the Financial Statements. If the timing of the reversal of temporary differences cannot be clearly determined, the tax rate in effect at the end of the fiscal year following the date of the Statement of Financial Position is applied.

Income tax relating to items recognised in other comprehensive income is also recognised in other comprehensive income.

4.2 Other accounting policies

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

4.2.1 Cash and cash equivalents

Cash and cash equivalents include demand deposits and other highly liquid investments that are readily convertible to specific amounts of cash that are subject to an insignificant risk of changes in value.

4.2.2 Share capital, reserves and dividend distribution

Ordinary registered shares are recorded as an equity item. Costs directly related to an equity item are deducted from that equity item. Otherwise, that amount is recognised as an expense in the period to which it relates.

Where the Company purchases part of the Company's share capital (treasury shares), the amount paid including any costs, net of tax, is shown as a deduction from equity until the shares are cancelled or sold.

The number of treasury shares held by the Company does not reduce the number of shares outstanding, however it does affect the number of shares included in the earnings per share calculation.

TERNA ENERGY FINANCE S.P.S.A.

Annual Financial Report for FY 2023

( Amounts in Euro thousand unless stated otherwise)

58

Specifically, reserves are divided into:

Ordinary reserve: According to the Greek Commercial Code, companies must transfer a minimum of 5% of their annual net profits to an ordinary reserve, until this reserve becomes equal to 1/3 of the paid-up share capital. This reserve cannot be distributed during the life of the company.

Dividends: Dividends distributed to the Company's shareholders are recognised in the Financial Statements as a liability in the period in which the management's distribution proposal is approved by the Annual General Meeting of Shareholders. Also, at the same time, the effect of the distribution of results approved by the Annual General Meeting of Shareholders and any formation of reserves is reflected in the Financial Statements.

4.2.3 Operating Segments

The Company's Board of Directors is the principal business decision maker and reviews internal financial reporting in order to assess the Company's performance and make decisions on the allocation of resources. Management has determined the business segment based on these internal reports.

The operating segment of TERNA ENERGY is defined as the segment in which the Company operates and on which the Company's internal reporting system is based (see in detail Note 5).

4.2.4 Employee benefits

Short-term benefits: Short-term employee benefits (other than termination benefits) in cash and in kind are recognized as an expense when they become accrued. Any unpaid amount is recorded as a liability, and if the amount already paid exceeds the amount of the benefits, the enterprise recognizes the excess as an asset (prepaid expense) only to the extent that the prepayment will result in a reduction in future payments or a refund.

Post-employment benefits: Post-employment benefits include lump-sum retirement benefits, pensions and other benefits paid to employees after termination of employment in exchange for their service. The Company's obligations for retirement benefits relate to both defined contribution plans and defined benefit plans. The accrued cost of defined contribution plans is expensed in the period to which it relates. The pension plans adopted by the Company are partially funded through payments to insurance companies or state social insurance institutions.

(a) Defined contribution plan

Defined contribution plans involve the payment of contributions to Insurance Institutions, so that the Company does not incur a legal obligation if the Institution fails to pay the benefit to the insured. The employer's obligation is limited to the payment of employer contributions to the Institutions. The contribution payable by the Company to a defined contribution plan is recognized as a liability after deducting the contribution paid, while the accrued contributions are recognized as an expense in profit or loss.

(b) Defined benefit plan (unfunded)

In accordance with Law 2112/20, Law 4093/2012 and Article 8 of Law 3198/1955, the Company pays employees severance payments upon dismissal or retirement due to retirement. The amount of compensation paid depends on the years of service, the amount of remuneration and the method of separation from service (dismissal or retirement). Entitlement to participate in these schemes is

TERNA ENERGY FINANCE S.P.S.A.

Annual Financial Report for FY 2023

( Amounts in Euro thousand unless stated otherwise)

59

established through the distribution of benefits over the last 16 years until the employees' retirement date following the scale of Law 4093/2012.

The liability recognized in the Statement of Financial Position for defined benefit plans is the present value of the defined benefit obligation less the fair value of plan assets (reserve from payments to the insurance company) and changes arising from any actuarial gain or loss and past service costs. The defined benefit obligation is calculated annually by an independent actuary using the projected unit credit method.

Based on all of 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 European bond index for the estimated duration of the plan at the valuation date. The value of the benchmark index as at 31/12/2022 was 2.95% , 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 defines, based on various parameters such as age, years of service and salary, specific obligations for benefits payable. The provisions relating to the period are included in the related personnel costs in the accompanying Statements of Income and consist of current and past service costs, related financial costs, actuarial gains or losses and any potential additional charges. With respect to unrecognized actuarial gains or losses, the revised IAS 19 is followed, which includes a number of amendments to the accounting for defined benefit plans, including:

I. the recognition of actuarial gains/losses in other comprehensive income and their final exclusion from profit or loss,

II. no longer recognizing the expected return on plan investments in profit or loss but recognizing the related interest on the net benefit obligation/(liability) calculated using the discount rate used to measure the defined benefit obligation,

III. recognizing past service cost in profit or loss on the earlier of the date of the plan amendment or when the related restructuring or termination benefit is recognized,

IV. Other changes include new disclosures, such as quantitative sensitivity analysis.

4.2.5 Provisions, Contingent Liabilities and Contingent Assets

Provisions are recognized when the Company has present legal or constructive obligations as a result of past events, it is probable that they will be settled through outflows of resources and a reliable estimate of the amount of the obligation can be made. Provisions are reviewed at each financial statement reporting date and adjusted to reflect the present value of the expenditure expected to be required to settle the obligation. Where the effect of the time value of money is significant, the amount of the provision is the present value of the expenditure expected to be required to settle the obligation.

If it is no longer probable that an outflow of resources will be required to settle a liability for which a provision has already been recognised, the provision is reversed.

In cases where an outflow of resources as a result of present obligations is not considered probable, or the amount of the provision cannot be estimated reliably, no liability is recognised in the financial statements. Contingent liabilities are not recognised in the financial statements but are disclosed unless the probability of an outflow of resources embodying economic benefits is remote. Potential

( Amounts in Euro thousand unless stated otherwise)

60

inflows of economic benefits to the Company that do not yet qualify as an asset are considered contingent assets and are disclosed if the inflow of economic benefits is probable.

5. INFORMATION REGARDING OPERATING SEGMENTS

An operating sector is a component of an economic entity: a) that engages in business activities from which it may earn revenues and incur expenses (including revenues and expenses that concern transactions with other components of the same economic entity) and, b) whose operating results are regularly reviewed by the chief operating decision maker of the entity to make decisions about resources to be allocated to the segment and assess of its performance. The term “chief operating decision maker” defines the function of the Company that is responsible for the allocation of resources and the assessment of the economic entity’s operating segments. For the application of IFRS 8, this function is assigned to the Managing Director (Chief Executive Officer). An entity presents separately the information on each operating segment that meets certain criteria of characteristics and exceeds certain quantitative limits. The above information is presented in the accompanying consolidated statements of financial position, comprehensive income, and cash flows according to the IFRS, whereas previously recorded operating segments – as presented in the financial statements of the previous financial year ‐ require no modifications.

The Company recognizes only one operating reporting segment while there are no less significant segments that would be consolidated into the category of other segments. In particular, the only sector in which the Company operates is the Investment and Finance sector in Greece and therefore the total amounts of the Statement of Financial Position and the Statement of Comprehensive Income relate exclusively to the Company's activity in this field.

6. OTHER LONG-TERM RECEIVABLES

The Company’s other long-term receivables as at 31/12/2023 and 31/12/2022, are analyzed as follows:

€150 million Common Bond Loan (CBL 2019)

In compliance with the Finance Prospectus as of 10/10/2019 and as of 10/10/2019 Bond Loan Issue Plan up to € 150 million and pursuant to the Agreement for Appointment of a Bondholders’ Representative (the “CBL Plan”), between TERNA ENERGY FINANCE S.A. (the Issuer), TERNA ENERGY S.A. (the Guarantor) and ATHEXCSD S.A. (Bondholders’ Representative), provisions are made for the issue of a CBL with a term of seven (7) years and amounting to one hundred and fifty million Euro (€ 150.000 thousand), divided into up to 150.000 intangible, common anonymous bonds with a nominal value of € 1,000 each.

On 22.10.2019, the Board of Directors of TERNA ENERGY FINANCE S.P.S.A. announced that the proceeds of the Public Offer amounted to € 150 million listing the Company’s bonds for trading in the ATHEX Regulated Market Securities Category. In particular, 150.000 common, bearer bonds of the Company with a nominal value of €1.000 (the Bonds) each have been allocated and as a result capital of an amount of €150 m. has been raised. The final yield of the Bonds was set at 2.60%, the Bond rate at 2,60% and the Loan Disposal Price at € 1.000 each, i.e. 100% of its nominal value. The final registration of the bonds in the Beneficiary Accounts of the Intangible Securities System was completed on 22.10.2019.

To secure the Company’s loan, corporate guarantee was provided by the parent company TERNA ENERGY INDUSTRIAL COMMERCIAL TECHNICAL SOCIETE ANONYME (hereafter called as “TERNA ENERGY S.A.” or the Guarantor).

Under the terms of the Common Bond Loan Issue Plan of up to € 150.000.000 and the Bondholders’ Representative Appointment Agreement dated 10/10/2019, the raised funds of € 150.000 thousand will be invested by the Issuer to the Guarantor through the Intra-group Loan. On 21/10/2019, the Guarantor issued a bond loan under Law 3156/2003, within the frame of the Intragroup Loan Scheme, which was covered by the Issuer for an amount of € 146.632 thousand. This way, the respective

amount of the CBL was transferred to the Guarantor, thus lending the equal amount of the capital proceeds to the Guarantor, so that the latter could use it in respect of its investment plan as analyzed in section 4.1.2 of the Prospectus as of October 10th, 2019.

As of 31/12/2023 the outstanding amount of CBL 2019 had settled at € 149.105 thousand.

At the repetitive meeting of the Bondholders of the Common Bond Loan that took place on December 15, 2023, the obligation of the Company and the Guarantor to ensure compliance with the ratios (a) Debt to Equity and (b) Net Debt to EBITDA, was eliminated.

The income tax return is submitted on an annual basis, but the declared profits or losses remain temporary until the tax authorities audit the taxpayer's books and records and the final audit report is issued.

The Company makes an annual assessment of any liabilities that are expected to arise from the audit of previous years, making relevant provisions where necessary.

The Company has not made any provisions for unaudited fiscal years as the Management considers that any tax amounts that may arise will not have a material effect on the Company's equity, results and cash flows. The unaudited fiscal years are from 2018 to 2023.

The Company has been subject for the years from 2018 to 2023 to the optional tax audit of the Chartered Accountants, as detailed in Note 22.

17. EARNINGS PER SHARE

Basic earnings per share for the annual period 01/01/2023 – 31/12/2023 and for the respective comparative period of 2022 were calculated by dividing the net earnings attributed to shareholders of the parent company by the weighted average number of outstanding shares as follows:

On 23/05/2023, ICAP S.A. conducted a periodic reassessment of the credit rating of the Guarantor company "TERNA ENERGY S.A.", where it maintained its credit rating at AA and placed it in low credit risk category.

Maintaining the above credit rating reflects:

- maintaining the Group's competitive position despite the divestment from the US market and the volatility in the energy market,

- the satisfactory capital structure and leverage ratios over time at Group level, given the investments made,

- the maintenance of high cash liquidity (1,5x) over the three-year period under review,

- the Group's large energy portfolio, its significant market position and the wide geographic spread of projects,

- the ongoing investment activity, which creates the conditions for the stabilization of an increased revenue stream and profitability on a long-term basis.

As of December 31st, 2023 there are no financial receivables overdue.

19.4 Liquidity risk

The Company manages its liquidity needs by carefully monitoring the debts of long-term financial liabilities as well as payments made daily. Liquidity needs are monitored in different time zones, on a daily and weekly basis, as well as in a rolling 30-day period. Liquidity needs for the next 6 months and the following year are determined on a monthly basis. In essence, the Company's basic liquidity needs pertain to the repayment CBL 2019 interest (see Note 10), primarily covered by the interest inflows arising from CBL 2019 (see Note 6).

The Company maintains cash and bank deposits in order to meet liquidity needs for periods of up to 30 days. Fund for medium-term liquidity needs are released from time deposits of the Company.

The Company is not exposed to market risk for its financial assets.

19.6 Summary Report of Risks of TERNA ENERGY S.A. (sole shareholder and guarantor of CBL 2019)

As previously mentioned, (see Note 1), the Company is operationally supported by its parent company, TERNA ENERGY S.A., which fully influences and controls the decisions, management and operation of the Company. In the case that TERNA ENERGY S.A. ceases to assist the Company in its management and operation or is unable to fulfil its contractual obligations to the Company under the terms of the Interim Loan, this may have material adverse effects: a) on the Company's ability to fulfil its obligations, mainly due to insufficient cash flow and revenues; b) on the trading price of the Company's Bonds on the X. Α., (c) the results of operations, financial condition and prospects of the Company.

Considering the above, the main risks and uncertainties in the Company's activities are directly related to those of the TERNA ENERGY Group (hereinafter "Group") and therefore, the report on the Company's Principal Risks & Uncertainties should be considered together with the report on the risks of the TERNA ENERGY Group.

In synopsis, we present the main risks and uncertainties in the activities of the TERNA ENERGY S.A. Group, as described in the published financial statements for the year ended 31/12/2023 and which are summarized in the following:

The Group's activities expose it to various financial risks such as market risk (including currency risk, interest rate risk and price volatility risk), credit risk and liquidity risk.

To manage financial risks and limit their negative impact on the Group's financial results, the Group monitors the fluctuations in variables affecting costs and sales and uses appropriate instruments as appropriate.

The main risks and uncertainties in the Group's activities are the following:

i. Foreign exchange risk

The Group operates, apart from Greece, in Eastern Europe and therefore may be exposed to foreign exchange rate risk arising from the exchange rate of the euro against other currencies. This type of risk can only arise from commercial transactions in foreign currencies, from investments of financial assets denominated in foreign currencies, as well as from net investments in foreign entities. In order to limit this risk, the Group utilizes 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.

ii. 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 31/12/2023, 16,21%of long-term loans received by

TERNA ENERGY FINANCE S.P.S.A.

Annual Financial Report for FY 2023

( Amounts in Euro thousand unless stated otherwise)

70

the Group bear a fixed interest rate, 65,98% 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 17,80% 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% ( 2022: +/- 20% also). The changes in interest rates are estimated to fluctuate on a normal basis in relation to current market conditions and until today they remain stable compared to the previous Fiscal Year.

The Group is not exposed to other interest rate risks.

iii. 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 hedges of this risk given that any impact is not expected to be significant.

iv. Credit risk.

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

The energy sector accounts receivable are all related to the wider public sector both domestically (including ENEX, DAPEP, HEDNO, OASA, ASDA) and internationally, and the same applies to the concessions sector, as well as most of the construction sector receivables.

The Group has 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.

Annual Financial Report for FY 2023

( Amounts in Euro thousand unless stated otherwise)

71

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.

v. Liquidity risk analysis

The liquidity of the Group is considered satisfactory, as, in addition to the existing cash, the operating wind farms generate continuous, satisfactory cash flows. Net cash flows in 2023 from continuing operating activities amounted to € 134 million compared to € 110 million in 2022. The Group manages its liquidity needs through regular cash planning, careful monitoring of long-term financial liabilities and methodical management of payments made on a daily basis. Liquidity needs are monitored in different time zones, on a daily and weekly basis and on a 30-day rolling period. Liquidity needs for the next 6 months, and the following year are determined monthly.

vi. Other risks and uncertainties

The Group remains exposed to short‐term fluctuations of wind and hydrologic data, a fact, which does not affect the long‐term efficiency of its projects, as prior to the implementation of the investments extensive studies take place with regards to the long‐term behavior of such factors.

The construction sector of TERNA ENERGY is subject to significant fluctuations, both with regards to turnover and with regards to the profitability of each construction project, because the construction activity, particularly of specialized companies such as TERNA ENERGY, entails increased volatility that is mainly related to the ongoing renewal of the backlog of construction agreements towards third parties, which are mainly public entities.

(a) Special note to the war conflict in the region of Ukraine

The effects of this military conflict in Ukraine, which had a significant impact on the electricity market where the Group operates, seem to have stabilised. However, the risk is significant as long as there is no overall resolution of the conflict. In any case, considering the nature of the transactions carried out by the Group's companies, there was no direct impact on the Group's size and performance and none is expected in the future. Other risks such as the fluctuation of expected government revenues in the tourism sector, energy and grain price inflation and uncertainty in the development of foreign direct investment continue to be variables that may affect fiscal flexibility and the broader economic climate with unavoidable indirect consequences for the Group.

22. CONTINGENT LIABILITIES

22.1 Ανέλεγκτες φορολογικά χρήσεις

The tax obligations of the Company are not definitive as there are unaudited tax years (2018 to 2023). For the unaudited tax years there is the possibility of imposing additional taxes and surcharges at the time when they will be examined and finalized. The Management considers that any amounts of taxes that may arise, will not have a significant effect on the Company's equity, results and cash flows and therefore as at 31/12/2023 the Company has not recognized provisions for tax unaudited years. Upon completion of these tax audits by the competent authorities, if they are finally carried out, the Management does not expect significant tax liabilities to arise.

Tax Compliance Certificate

For the years 2018 to 2022, the Company received a Tax Compliance Report, according to article 65A par. 1 of Law 4174/2013, without substantial differences. According to Circular POL. 1006/2016, the companies which have been subject to the above special tax audit are not exempted from the regular tax audit by the competent tax authorities. Furthermore, according to the relevant legislation, for the years 2016 onwards, the audit and issue of the Tax Compliance Certificate is valid on a voluntary basis.

The special audit for the issue of Tax Compliance Certificate for the year 2023, is in progress and the relevant tax certificate is expected to be issued after the publication of the Financial Statements for the year ended as of 31/12/2023. At the completion of these tax audits, provided they are finally conducted, the Management does not expect any significant tax liabilities to arise. If additional tax obligations arise, it is estimated that they will not have a material effect on the Financial Statements.

22.2 Legal cases

In the course of its operations, the Company may be faced with possible legal claims of third parties. According to both the Management and the Company's Legal Consultant, there are no litigation or arbitration disputes involving judicial or arbitration bodies concerning the Company.
