After its successful participation in the contest by CMA Kuwait to privatize Boursa Kuwait, ATHEX is a shareholder of Boursa Kuwait with a 0.779% stake, corresponding to 1,564,500 shares.

The shares of Boursa Kuwait began trading in the Kuwait organized securities market on 14.09.2020. On 30.06.2025 the shares posted a valuation gain of €2.0m compared to 31.12.2024 which is accounted in the special securities valuation reserve.

Third party balances in ATHEXClear bank accounts

The Group, through its subsidiary ATHEXClear is aligned with the corporate governance framework determined by Regulation (EU) 648/2012 of the European Parliament and Council (EMIR Regulation), and keeps all cash collaterals that are being managed by the Company and concern the cash market and the derivatives market, as well as the cash balances of ATHEXClear, in an account it maintains at the Bank of Greece (BoG) as a direct participant over the internet to the TARGET2-GR Express Transfer of Capital and Settlement System in real time (TARGET2-GR).

Therefore, its own cash balance and the balances of third parties (margins) are deposited in the same account that ATHEXClear maintains at the Bank of Greece, and as a result a separation of the assets is necessary for the collateral that ATHEXClear collects to be shown separately in the current assets of 30.6.2025. In the Statement of Financial Position of 30.6.2025, they are reported as equal amounts in both current assets and short-term liabilities as "third party balances at the Company bank account" and concern exclusively the margins in the derivatives market that were deposited in the bank account that ATHEXClear maintains at the BoG on 30.6.2025.

Prospects for 2025 and beyond

The Greek economy is maintaining its momentum, despite the challenges of the international environment. GDP grew by 2.2% in the first quarter of 2025, significantly exceeding the eurozone average. The continuation of the growth trajectory, combined with the ongoing – albeit slow – decline in inflation, strengthens the prospects for steady economic progress in the coming years. Forecasts point to growth of 2.3% in 2025 and stable levels of around 2% until 2027, with inflation remaining at controlled levels.

Financial conditions are being strengthened by the easing of interest rates at the international level, while yields on Greek government and corporate bonds continue their downward trend, reflecting the improvement in the country's credit rating. The continuous upgrades of Greek bonds to investment grade are a decisive factor in attracting international investor interest.

The steady upward trend of the Greek capital market is supported by the strong fundamentals of listed companies, both banking and non-banking. 2024 was a landmark year, with the best performance in 19 years in key financial indicators such as EBITDA, operating cash flow, equity, and liquidity. Non-banking companies recorded record EBITDA (€14.8 billion), enhanced profitability (€6.8 billion), increased operating cash flows, and significant investments (CAPEX over €10 billion). At the same time, banks recorded a significant increase in their net profitability (+10.5%), while also boosting returns to their shareholders with dividends of €1.5 billion for 2024.

Of particular importance is the strengthening of the Greek capital market, which continues to show strong growth. The Athens Stock Exchange General Index rose by 34.0% in the first seven months of 2025 (to 25.7), reaching 1,968.72 points, while the average daily turnover increased by 45.6% on an annual basis, exceeding €200 million.

In this context, the Greek capital market is now being monitored by international rating agencies for a possible upgrade to the developed markets category by organizations such as S&P Dow Jones, FTSE Russell, and Stoxx. The possibility of this upgrade further strengthens the country's investment narrative.

In conclusion, despite ongoing international geopolitical uncertainties, the Greek economy and capital market are showing clear signs of resilience and positive prospects, with domestic developments acting as a stabilizing factor and catalyst for further upgrading the country's investment profile.

Turnover – risks and uncertainties

Besides the fees from trading that takes place in the ATHEX markets and which are collected through the Members, important revenue streams for the Athens Exchange Group are also fees from orders and Member terminals, revenue from Member and Operator subscriptions, revenue from subscriptions and rights issues of listed companies and corporate actions in general, revenue from data vendors, revenue from administrative, IT and IT support services, educational services etc.

The turnover of the Group depends, to a large extent, on factors over which it has no influence, since they are connected with developments in the Greek capital market, which in turn are affected by a series of factors such as, the key financial data of listed companies, the fundamental macroeconomic data of the Greek economy as well as developments in international capital markets.

Contrary to revenues, which cannot be controlled by the companies of the Group, on the cost side concerted efforts are being made to rationalize them, in order to improve the financial results of the Group and allocate them in activities of added value.

Risk Management

In an increasingly interconnected global financial landscape, ATHEXGROUP recognizes that sound and proactive risk management is not merely a compliance function but an essential pillar supporting the Group's long-term strategic objectives. ATHEXGROUP's risk management framework is a dynamic, and integral element that ensures operational resilience, safeguards the integrity of the capital market, and mitigates risks inherent in an ever-evolving financial and regulatory environment. Through a comprehensive and forward-looking risk management approach, the Group strives to maintain market stability, protect stakeholders, and promote innovation in a manner that is both sustainable and strategically aligned with the Group's vision.

Risk Management approach

The Group's risk management approach integrates the identification, evaluation, and mitigation of risks across all operational, financial, and strategic domains. This holistic approach ensures that risk is managed within clearly defined boundaries, as established by the Group's risk appetite, which aligns with both the Group's strategic ambitions and its regulatory obligations. Besides the risk appetite, the key components ensuring the effectiveness of the Group's risk management approach include the establishment of a risk inventory, linked to the risk taxonomy and the systematic risk assessment approaches, the transparent risk event management process, the continuous monitoring of key risk indicators (KRIs), the implementation of rigorous internal controls, and the application of advanced stress testing techniques, all of which are essential to assessing the Group's exposure to both current and emerging risks.

Risk Governance

At the core of ATHEXGROUP's risk management approach is a robust governance framework that ensures all material risks are properly identified, assessed, quantified, and managed. This governance approach is designed to not only manage risks proactively but also to ensure that risk considerations are embedded into the Group's strategic initiatives, business plan, and innovation-driven projects. The Board of Directors retains ultimate responsibility for the Group's risk strategy, with oversight and guidance provided by the Risk Committee, which operates with a clear mandate to ensure the effectiveness and integrity of risk management processes across the Group.

The Group's risk management function is led by the Group Chief Risk Officer (GCRO), who is charged with maintaining the independence and objectivity of risk oversight provides executive leadership for the implementation of risk management policies and strategies. Reporting directly to the Risk Committee, the GCRO ensures that risk management activities are aligned with the Group's strategic goals and the broader regulatory environment, supporting the Group to adapt to emerging risks and leverage opportunities. The Risk Units work closely with operational units, internal audit, and compliance teams to instill a culture of risk awareness throughout the organization.

ATHEXGROUP follows the principles of the 3 lines of defense model to ensure effective risk governance. The 1st line is operational management, which is directly responsible for identifying, managing, and mitigating risks within their respective functions, while implementing controls and adhering to established risk policies. The 2nd line comprises of the risk management and compliance functions, with risk management overseeing the identification, assessment, and mitigation of risks. The compliance function, ensures that the Group adheres to all relevant regulations and internal policies. The 3rd line, Internal Audit, provides independent assurance by evaluating the overall effectiveness of the risk management framework and internal controls, offering recommendations for continuous improvement.

Principle Risks Managed

Credit Risk: Credit risk arises from the possibility that a counterparty or market participant may fail to meet its financial obligations, including payment or settlement. This risk is particularly relevant in the Group's clearing and settlement functions, where counterparty default could lead to systemic disruptions. The management of credit risk entails rigorous counterparty assessments, the establishment of collateral arrangements, and the

implementation of exposure limits, ensuring that the Group is safeguarded against the default of key market participants. The Group implements a sophisticated set of risk management tools to accurately quantify and effectively manage credit risk (VaR models, stress testing, Margin/Haircut Back-Testing, Default Fund Coverage under Stress).

Market Risk: Market risk pertains to the potential for financial loss resulting from adverse fluctuations in market prices, including interest rates, foreign exchange rates, or the value of financial instruments. The Group's exposure to market risk is negligible.

Liquidity Risk: Liquidity risk reflects the possibility that ATHEXGROUP may face difficulties in meeting its financial obligations due to an imbalance between liquid assets and liabilities (assets held as liquidity reserve), losses triggered by high liquidity funding cost or suspension of payments when it comes to CCP. To manage liquidity risk, the Group maintains robust liquidity buffers, performing daily liquidity controls through stress tests, thereby safeguarding its ability to maintain operations even under adverse conditions.

Operational Risk: Operational risk encompasses the potential for loss resulting from the failure of internal processes, systems, people, or external events, including fraud, human error, or technological breakdowns. In an increasingly digital and interconnected environment, this risk is amplified by system vulnerabilities, cyber threats, and dependency on critical infrastructure. The Group proactively addresses operational risks by investing in cutting-edge technologies, strengthening internal controls, conducting regular vulnerability assessments, and ensuring business continuity through comprehensive disaster recovery planning.

Legal and Compliance Risk: Legal and compliance risk arises from the possibility of regulatory sanctions, legal penalties, or reputational damage stemming from a failure to comply with applicable laws, regulations, or internal policies. In an environment of continuously evolving regulatory requirements, particularly within the financial markets, the Group's compliance function plays a pivotal role in minimizing this risk. ATHEXGROUP ensures continuous legal oversight, engages in proactive regulatory monitoring, and fosters a culture of compliance to mitigate the risk of non-compliance and safeguard its reputation.

ICT Risk: Information and Communication Technology (ICT) risk pertains to the threat of disruption to the Group's operations due to technological failures, cyber-attacks, data breaches, or inadequacies in IT infrastructure. As financial markets become increasingly reliant on digital platforms, this risk has become more pronounced. The Group mitigates ICT risk through the deployment of state-of-the-art cybersecurity measures, the establishment of secure data management protocols, and the implementation of continuous system monitoring and response mechanisms to safeguard its technological infrastructure from potential threats.

2025

In 2025, the Risk Management Division remained steadfast in its commitment to fortify the organization's risk management framework, with a clear focus on refining risk identification, assessment, and mitigation processes. As part of its approach to ensuring compliance with the Digital Operational Resilience Act (DORA), the Division was actively involved in reviewing, streamlining, and aligning internal processes. This is part of a broader, strategic effort to elevate the organization's resilience by enhancing risk monitoring capabilities, optimizing business continuity planning, and reinforcing third-party risk management, ensuring a robust, future-ready operational environment.

Future Risk Considerations

As ATHEXGROUP continues to evolve, it remains mindful of emerging risks that could affect its operations.

  • Technological Disruption: The advent of new technologies, such as blockchain and decentralized finance, presents both opportunities and challenges for traditional exchanges. ATHEXGROUP is exploring the potential integration of these technologies while carefully managing the associated risks.
  • Geopolitical and Macroeconomic Risks: ATHEXGROUP continuously monitors global geopolitical developments, economic trends, and regulatory changes to assess their potential impact on the Greek financial markets. This vigilance enables the group to adapt proactively to changes in the global financial landscape.

Significant events after 30.06.2025

Athens, 28 July 2025 The Board of Directors

Alternative Performance Measures

An Alternative Performance Measure (APM) is an adjusted financial measurement of past or future financial performance, financial position or cash flows that is different from the financial measurement defined in the applicable financial reporting framework. In other words, an APM on the one hand is not exclusively based on financial statement standards, and on the other it provides material supplementary information, excluding items that may potentially differentiate from the operating results or the cash flows.

Transactions with a non-operational or non-cash valuation that have a significant effect in the Statement of Comprehensive Income are considered items that affect the adjustment of the indices to APMs. These, nonrecurring in most cases, items may arise among others from:

  • Asset impairments
  • Restructuring measures
  • Consolidation measures
  • Sale or transfer of assets
  • Changes in legislation, compensation for damages or legal claims

APMs must always be taken into consideration in conjunction with the financial results that have been drafted based on IFRS, and in no instance should they be considered as replacing them. The Athens Exchange Group used APMs for the first time in fiscal year 2016, in order to better reflect the financial and operational performance related to the activity of the Group as such in the fiscal year in question, as well as the previous comparable period.

The definition, analysis and calculation basis of the APMs used by the Group is presented below.

Items affecting the adjustment

In accordance with the financial statements for the first half of 2025, the items that affect the adjustment of the indices used by the Group in order to calculate APMs is the valuation of the participations in Boursa Kuwait and the Belgrade Stock Exchange, as shown in detail in the table below:

Independent Auditors' Review Report

To the Board of Directors of HELLENIC EXCHANGES - ATHENS STOCK EXCHANGE S.A.

Review Report on Interim Financial Information

Introduction

We have reviewed the accompanying condensed separate and consolidated statement of financial position of HELLENIC EXCHANGES - ATHENS STOCK EXCHANGE S.A. as of 30 June 2025 and the related condensed separate and consolidated statements of comprehensive income, changes in equity and cash flows for the sixmonth period then ended, and the selected explanatory notes that comprise the interim condensed financial information, which forms an integral part of the six-month financial report under Law 3556/2007.

Management is responsible for the preparation and fair presentation of this interim condensed financial information, in accordance with the International Financial Reporting Standards, as adopted by the European Union and apply for Interim Financial Reporting (International Accounting Standard "IAS 34"). Our responsibility is to express a conclusion on these interim condensed financial statements based on our review.

Scope of Review

We conducted our review in accordance with International Standard on Review Engagements 2410, "Review of Interim Financial Information Performed by the Independent Auditor of the Entity". A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with International Standards on Auditing, as incorporated into the Greek Legislation, and consequently, does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe that the accompanying interim condensed financial information is not prepared, in all material respects, in accordance with IAS 34.

Report on Other Legal and Regulatory Requirements

Based on our review, we did not identify any material misstatement or error in the representations of the members of the Board of Directors and the information included in the six-month Board of Directors Management Report, as required under article 5 and 5a of Law 3556/2007, in respect of the accompanying condensed separate and consolidated financial information.

In particular, the Management of the Group and the Company, considering the current and projected financial position of the Group and the Company and their liquidity levels (including the observance of medium-term budgets) estimates that the use of the going concern principle when preparing the attached interim financial statements is appropriate.

5.2.2. Key estimates and judgements

The preparation of financial statements in accordance with the International Financial Reporting Standards requires that the Management of the Group make important assumptions and accounting estimates that affect the balances of the Asset and Liability accounts, the disclosure of contingent claims and liabilities on the preparation date of the Financial Statements, as well as the revenues and expenses presented in the period in question. Despite the fact that these estimates are based on the best possible knowledge of the management of the Company as regards the current conditions, actual results may differ from these estimates in the end.

Estimates and judgments are continuously evaluated, and are based on empirical data and other factors, including anticipation of future events that are to be expected under reasonable conditions. The significant estimates and judgements used in drafting the attached financial statements are presented in note 5.2.2 of the 2024 Annual Financial Report.

5.3. Accounting Principles and new Standards

5.3.1. Accounting Principles

The accounting principles (key and other) adopted by the Group and the Company for the preparation of the attached financial statements for the 1st half of 2025 do not differ from those used for the publication of the 2024 Annual Financial Report that has been audited by the certified auditors-accountants of the Group and is posted on the internet at www.athexgroup.gr.

5.3.2. New standards, amended standards and interpretations

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 01.01.2025. The estimate of the Group concerning the effect of these new standards, amended standards and interpretations is provided below:

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 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 01.01.2025. The Amendments do not have an impact on the consolidated Financial Statements.

New Standards, Interpretations, Revisions and Amendments to existing Standards that have not been applied yet or have not 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), but their application has not started yet or they have not been adopted by the European Union.

IFRS 9 & IFRS 7 "Amendments to the Classification and Measurement of Financial Instruments" (effective for annual periods starting on or after 01.01.2026)

In May 2024, the International Accounting Standards Board (IASB) issued amendments to the Classification and Measurement of Financial Instruments which amended IFRS 9 "Financial Instruments" and IFRS 7 "Financial Instruments: Disclosures". Specifically, the new amendments clarify when a financial liability should be derecognised when it is settled by electronic payment. Also, the amendments provide additional guidance for assessing contractual cash flow characteristics to financial assets with features related to ESG-linked features (environmental, social, and governance). IASB amended disclosure requirements relating to investments in equity instruments designated at fair value through other comprehensive income and added disclosure requirements for financial instruments with contingent features that do not relate directly to basic lending risks and costs. The amendments are effective from annual reporting periods beginning on or after 1 January 2026. The Group will examine the impact of the above on its Financial Statements. The above have been adopted by the European Union with an effective date of 01.01.2026.

Annual Improvements to IFRS Standards-Volume 11 (effective for annual periods starting on or after 01.01.2026)

In July 2024, the IASB issued the Annual Improvements to IFRS Accounting Standards-Volume 11 addressing minor amendments to the following Standards: IFRS 1 'First-time Adoption of International Financial Reporting Standards', IFRS 7 'Financial Instruments: Disclosures', IFRS 9 'Financial Instruments': IFRS 10 'Consolidated Financial Statements', and IAS 7 'Statement of Cash Flows'. The amendments are effective for accounting periods on or after 1 January 2026. The Group will examine the impact of the above on its Financial Statements. The above have been adopted by the European Union with an effective date of 01.01.2026.

Amendments to IFRS 9 and IFRS 7 "Contracts Referencing Nature-dependent Electricity" (effective for annual periods starting on or after 01.01.2026)

On 18 December 2024 the International Accounting Standards Board (IASB) issued amendments to IFRS 9 "Financial Instruments" and IFRS 7 "Financial Instruments: Disclosures" to help companies better report the financial effects of nature-dependent electricity contracts, which are often structured as power purchase agreements (PPAs). Nature-dependent electricity contracts help companies to secure their electricity supply from sources such as wind and solar power. The amount of electricity generated under these contracts can vary based on uncontrollable factors such as weather conditions. The amendments allow companies to better reflect these contracts in the financial statements, by a) clarifying the application of the 'own use' requirements, b) permitting hedge accounting if these contracts are used as hedging instruments and c) adding new disclosure requirements to enable investors to understand the effect of these contracts on a company's financial performance and cash flows. The amendments are effective for accounting periods on or after 1 January 2026, with early application permitted. The Group will examine the impact of the above on its Financial Statements. The above have been adopted by the European Union with an effective date of 01.01.2026.

IFRS 18 "Presentation and Disclosure in Financial Statements" (effective for annual periods starting on or after 01.01.2027)

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

IFRS 19 "Subsidiaries without Public Accountability: Disclosures" (effective for annual periods starting on or after 01.01.2027)

In May 2024 the International Accounting Standards Board issued a new standard, IFRS 19"Subsidiaries without Public Accountability: Disclosures". The new standard allows eligible entities to elect to apply IFRS 19 reduced disclosure requirements instead of the disclosure requirements set out in other IFRS. IFRS 19 works alongside other IFRS, with eligible subsidiaries applying the measurement, recognition and presentation requirements set out in other IFRS and the reduced disclosures outlined in IFRS 19. This simplifies the preparation of IFRS financial statements for the subsidiaries that are in-scope of this standard while maintaining at the same time the usefulness of those financial statements for their users. IFRS 19 is effective from annual reporting periods beginning on or after 1 January 2027, with early adoption permitted. The Group will examine the impact of the above on its Financial Statements. The above have not been adopted by the European Union.

5.4. Segment Information

In accordance with the provisions of IFRS 8, the determination of operating segments is based on a "management approach." Based on this approach, information that is disclosed for operating segments must be that which is based on internal organizational and managerial structures of the Group and the Company, and in the main accounts of the internal financial reports that are being provided to the chief operating decision makers. The chief business decision maker of the Group is the Chief Executive Officer (Executive member of the BoD).

An operating segment is defined as a group of assets and operations exploited to provide products and services, each of which has different risks and returns from other business segments. For the Group, the main interest in financial information focuses on operating segments since the company's electronic systems – located at its headquarters - are at the disposal of investors irrespective of their physical location.

On 30.06.2025, 31.12.2024 and 30.06.2024 the core activities of the Group were broken down in the following operating segments:

Management reasonably believes, taking into account the advice received from its legal/ tax advisors, that there is no risk of non-recovery of the receivable, on the one hand, due to the lack of an explicit legislative provision/ decision of an administrative court (or other competent body) on the impossibility of recovering (through repayment or offseting) the claim and, on the other hand, as the impossibility of recovering the above claim due to the change in the legislative regime would constitute a retroactive change in the tax treatment of certain taxable material, in violation of Article 78 par. 2 of the Constitution. At the same time, the Group's Management intends to take further action in the near future to ensure its gradual recovery.

Tax Compliance Report

For fiscal years 2011 to 2015, the Greek Sociétés Anonymes and Limited Liability Companies whose annual financial statements must be audited were required to obtain an "Annual Certificate", as provided for in §5 article 82 of Law 2238/1994 and article 65A Law 4174/2013, which is issued after a tax audit carried out by the same statutory auditor or audit firm that audits the annual financial statements.

Starting with fiscal year 2016, the issuance of an "Annual Certificate" is optional. The tax authorities reserve the right to carry out a tax audit within the established framework as defined in article 36 of Law 4174/2013.

5.33. Litigation or arbitration disputes and other contingent liabilities

The Group is involved in litigation with former members and listed companies of the Athens Stock Exchange. The management of the Group and its legal counsel estimate that the outcome of these cases will not have a significant effect on the economic situation, financial position or the results of the operation of the Group and the Company.

5.34.Risk Policies and Management

A major consideration of the Athens Exchange Group (the Group) is the management of risk that arises from international developments in the sector, its business activities, and its business operation.

The Group, as operator of the capital market, has developed a framework for managing the risks to which it is exposed, ensuring its viability and development, and contributing to the stability and security of the capital market. Risk management is recognized as part of its supervisory functions which, together with the regulatory compliance system, form the second level of defense of the organization.

Market risk

The Group's and the Company's risk in relation to their investments derives primarily from any adverse changes in the current valuation prices of shares and other securities traded on organized markets. In particular, the Group and the Company hold on 30.06.2025 financial assets measured at fair value through other comprehensive income which mainly include the Group's investment in Boursa Kuwait (0.778%).

On 30.06.2025, the assets exposed to market risk amounted to €13,394 thousand for the Group and the Company. A change of ±10% in investments whose valuation gains or losses are recognized cumulatively in equity would result in a change of ±€1,339.4 thousand for the Group and the Company, respectively.

Liquidity risk

Liquidity risk is the risk of not being able to find sufficient cash to cover the Company's obligations.

The Group manages its liquidity needs through careful monitoring of scheduled payments for short-term liabilities as well as cash outflows from its day-to-day operations. Liquidity needs are monitored in various time frames (daily, weekly, monthly).

Liquidity risk is kept at a low level by maintaining sufficient cash reserves.

The Group's and the Company's trade and other payables of €11,367 thousand and €5,363 thousand respectively will be settled within the next 3 months.

Currency risk

The functional currency of the Group and the Company is the Euro. Most transactions of the Group and the Company take place in the functional currency, and as such, currency risk that arises from normal operations is limited.

The Group and the Company hold as of 30.06.2025 an investment in Boursa Kuwait (0.778%), whose shares are traded on the stock market of Kuwait since 14.09.2020 in Kuwaiti Dinars (KWD).

Also, a fair change in the RSD/EUR exchange rate of ±10% would result in a change in equity of ±€15 thousand for the Group and the Company.

5.35. Fair value

Measurement of fair value of financial assets

The financial assets and financial liabilities measured at fair values in the Statement of Financial Position of the Group and the Company are classified based on the following hierarchy into 3 Tiers for determining and disclosing the fair value of financial instruments by valuation technique:

Tier 1: Investments valued at fair value based on traded (unadjusted) prices in active markets for similar assets or liabilities.

Tier 2: Investments valued at fair value based on valuation models in which all inputs that significantly affect fair value are based (either directly or indirectly) on observable market data.

Tier 3: Investments valued at fair value based on valuation models in which inputs that significantly affect fair value are not based on observable market data.

The following tables present the financial assets that are measured at fair value on a recurring basis on 30.06.2025 and 31.12.2024. There are no financial liabilities measured at fair value at any of the periods presented.
