II. GENERAL REVIEW

Since early 2020 we are experiencing a unique new condition, with Covid-19 pandemic being spreading with speed bringing economic activity to a near-standstill, as countries imposed tight restrictions on movement to control the spread of the virus.

The collapse in global economic activity in 2020 due to the Covid-pandemic will be followed by a strong recovery of 6%, which for 2021 has been projected at around 5%.

Global trade, which has fallen by 5.3% in 2020, is now expected to grow by c.8% in 2021. The crash in international tourism and its closely linked sectors could cause a loss of more than US\$4tn for 2020 and 2021 alone. However, tourism is expected to experience a rapid recovery in countries with high vaccination rates and high intra-EU tourist flows, like Greece.

For Greece, real GDP contracted by 8.2% in 2020, among others due to the weaker-than-usual private consumption, services exports as well as due to the major impact lockdown had on Tourism. Similarly, to the rest of the world, Greece has experienced an improvement in economic activity during H1 2021, owing mainly to the gradual easing of the restrictive measures. In particular, Q1 2021 real GDP grew by 4.4% on a quarter-on-quarter basis, ranking Greece 4th in GDP growth among E.U. member states, while evidence shows that Greece could potentially achieve a double-digit growth during the second quarter of 2021. As vaccinations are gaining pace, expectations are improving and there is a firm belief that a new lockdown could be avoided. Thus, European Commission has revised upwards the growth forecast for Greece for 2021 to 4.3% and 6.0% for 2022, supported by the expected strong investment sentiment.

Along with the economic recovery, there are growing inflationary pressures, stemming from disruption in supply chain and bulk freights, the result of an unusually strong demand during the post-Covid restrictions era. Although inflation seems to be in transitory categories, it could be maintained until the economy reaches pre-Covid levels of employment, as expected at some point in H1 2022.

The eligibility waiver granted to Greek bonds under the Pandemic Emergency Purchase Programme (PEPP, in total €1.85bn) coupled with the Greek government's state guarantees, has resulted in a lower borrowing cost and an increase in bank credit lines for large Greek non-financial corporations. Equally important, a temporary instrument designed by the EU to boost recovery (Next Generation EU recovery fund, >€800bn) will eventually substitute the benefits of PEPP.

MYTILINEOS, following developments closely, continues its expansion programme, in-line with the ambitious environmental goals that have been set.

In view of significant investments that have being either implemented or recently launched, MYTILINEOS successfully issued its first «green» bond of €500m priced at 2.25% with maturity in 2026, which will help fund significant investments in promoting energy transition and sustainability while further improving its already excellent credit profile.

At the same time, MYTILINEOS has recently achieved the completion of two important agreements, with PPC regarding the supply of electricity and with GLENCORE for the sale of alumina and aluminum, setting the basis for even stronger profitability in the years to come.

III. REVIEW PER SECTOR

Metallurgy Business Unit

The news of tackling the pandemic through the vaccine development and production and its widespread availability, as well as the quantitative easing programs, announced by FED & ECB, for the support of large economies (U.S.A., EU), created a positive market environment, already seen since the second half of 2020, leading to the recovery of commodity prices. The increase in prices was further enhanced during H1 2021, the result of high demand, which was not met due to the decreased supply and the challenges in commodity transportation, which led to increased logistic costs.

The Aluminium price growth in H2 2020 continued throughout H1 2021 resulting in an average Aluminium price of LME 3M at 2.256\$/t, significantly higher compared to 1.622 \$/t, the price noted of the respective period in 2020 (+39%).

Extremely positive results were observed in the Aluminium premiums, as a result of the increased demand and the rising transportation cost. Compared to H1 2020, the billet's premiums reported a 30% increase.

The Alumina Price Index (API) reported a slight increase, with an average price in H1 2021 of 290 \$/t, a 9% increase compared to the respective period in 2020.

The US dollar declined with a USD/EUR exchange rate at 1.21, 10% weakening compared to H1 2020 (€/\$ 1.10).

The international economic recovery led to an increase in raw material prices (excluding bauxite), in energy prices (especially oil and natural gas), as well as an increase of the transportation costs and CO² prices, forcing higher production costs in H1 2021 by +25% for Alumina and by +15% for Primary Cast Aluminium compared to H1 2020.

The Metallurgy competitiveness initiative, "HEPHAESTUS" is in full deployment. The programme is expected to continue till the end of 2021, without any obvious delays in meeting its targets. H1 2021 has already marked a record cumulative Primary and Recycled Aluminium production and MYTILINEOS completed significant investments in Alumina production.

Sub-Sector's Update & Significant events

a. Third Party EPC

For Third party EPC activity, on the ''pros side'', the first semester of 2021 was a period of EPC contracts signing since its execution was on hold for a long time within 2020.

On the other hand, on the ''cons side'', the first semester was affected by continuous cost increases on the main equipment (solar modules, steel mounting structure) and by record high transportation expenses.

On top of that low PPA prices and increasing deviations with the spot power prices had also affected Investor's decisions and performance. Considering those facts Investors has shifted project's commencing to a later period, hoping to have cost reduction and better PPA prices.

Third Party EPC sub-segment performance during the first half of the year is outlined as below:

Power & Gas Business Unit

H1 2021 was characterized by (a) the continuation of the Covid19 pandemic which repressed the demand of electricity especially in the first quarter of the year and (b) by the extremely increased Gas and CO² prices, which resulted in the increase of the wholesale prices (DAM) affecting negatively the financial results of the retail power market.

The following graphs depicts the coverage (per source) of the total electricity demand (in TWh) for H1 2021 and H1 2020.

Despite the challenging circumstances due to the reduced demand, the Company's ability to source Natural Gas at competitive prices combined with the high efficiency rate, availability, reliability and flexibility of the Company's units (two combined cycle CCGT and one high efficiency Combined Heat and Power plant), led to a 2.13 TWh thermal plants' total production. This amount represents 8.8% of the total domestic electricity demand in the interconnected system and 23.6% of the Natural Gas production.

It is also noted that, in the context of maintaining the high efficiency rate, availability, reliability and flexibility of its units, MYTILINEOS proceeded with a successful 3-month "Major Inspection" of Korinthos Power Plant during the period between March to May. The power plant has been operating since early June, contributing to Greece's energy demand.

The Company's thermal and renewables units' total production reached 2.39TWh, a 9.8% share of the total demand.

MYTILINEOS, benefiting from the large Natural Gas portfolio, due to the high needs of the Company and its wholesale activities, as well as the long experience trading LNG and NG, through a wide network of international suppliers, continues to create new opportunities for NG supply on competitive terms. In H1 2021, MYTILINEOS share of total NG imports reached 21%.

Regarding energy supply, Protergia is steadily enforcing its presence in the retail market closing H1 2021 with approximately 315,000 electricity and NG meters, compared to 285,000 meters reported at the end of 2020. The electricity market share by the end of H1 2021 reached 8.2%.

The Company's RES production capacity reached 210.7 MW. In February, MYTILINEOS sold its minority shares of the ADERES Wind Park of 11.5 MW capacity, while at this time construction is under way of a new Wind Park of 43.2MW capacity.

At the RES bidding in May, the Company secured a Feed-in-Premium for 140MW Solar Energy from the EGNANTIA IKE pipeline.

The Company announced Joint Venture with Copenhagen Infrastructure Partners for the development and construction of offshore wind parks, after the required legal and regulatory framework is available.

Closing, the construction of the new 826MW Combined Cycle Gas Turbine (CCGT) unit with General Electric's H-Class gas turbine is proceeding normally and in accordance with the initial timeline. The launch of the power plant's trial operation is expected at the end of Q4 2021, strongly contributing to the country's transition to an energy mix with a significantly lower carbon footprint. The project is executed by the Company's Sustainable Engineering Solutions Business Unit with important synergies, ensuring reduced investment costs.

The Group's policy is to monitor its performance on a month to month basis thus tracking on time and effectively the deviations from its goals and undertaking necessary actions. The group evaluates its financial performance using the following generally accepted Key Performance Indicators (KPI's).

-EBITDA (Operating Earnings Before Interest, Taxes, Depreciation & Amortization): The Group defines the «Group EBITDA» quantity as profits/losses before tax, itemized for financial and investment results; for total depreciation (of tangible and intangible fixed assets) as well as for the influence of specific factors, i.e. shares in the operational results of liaised bodies where these are engaged in business in any of the business sectors of the Group, as well as the influence of write-offs made in transactions with the above mentioned liaised bodies.

- ROCE (Return on Capital Employed): This index is derived by dividing profit before interest, taxes, depreciation & amortization, to the total capital employed by the Group, these being the sum of the Net Position; Total Debt; and Long - term forecasts.

- ROE (Return on Equity): This index is derived by dividing profit after tax and minority interests by the Group's Net Position.

- EVA (Economic Value Added): This metric is derived by multiplying the total capital employed with the difference (ROCE – Capital Expenditure) and constitutes the amount by which the financial value if the company increases. To calculate the capital expenditure, the Group uses the WACC formula – « Weighted Cost of Capital».

The Weighted average cost of capital is calculated as, the quotient of Equity Capital to Total Capital Employed (Equity Capital and Debt) multiplied by the return on Equity* plus the quotient of Debt to Total Capital Employed (Equity Capital and Debt) multiplied by the return on Debt adjusted by the company tax rate (due to tax saving on interest paid).

$$WACC = \frac{E}{E+D}r_E + \frac{D}{E+D}r_D(1-Tc)$$

Where E Equity Capital D Debt rE Return on equity rD Return on debt Tc Tax rate

The calculation of the indicator Weighted Average Cost of Capital (WACC) for the 1st half of 2021 sums to 5.7%.

*Return on Equity is calculated by utilizing the "Capital Asset Pricing Model" (CAPM) and is equal to risk-free rate of return plus a risk premium multiplied by beta coefficient, which reveals the variability of the stock in relation to market fluctuations.

The above indicators for the presented period (on an annualized basis) as well as for the previous year, are as follows:

	2021	2020
EBITDA	325,628	283,008
ROCE	8.2%	8.3%
ROE	8.3%	8.3%
EVA	73,557	37,311

ΙΙΙ PROSPECTS – RISKS AND UNCERTAINTIES FOR THE SECOND HALF OF 2020

1. Prospects for the second half of 2021

Metallurgy Business Unit

The price increase, observed during H1 2021, seems to continue during H2 2021 with excellent dynamics in the Aluminum premiums and billets in particular, with a historical recorded performance in prices. Meanwhile, cost increase is also observed, the result of a combined increase in raw materials, transportation and energy costs. Alumina and bauxite prices are expected to remain stable, resulting from the supply and the dynamic of China's needs. We are expecting better selling prices, since the production costs are compressed by the energy prices and soda (NaOH) minimizing the factories' margins.

The "HEPHAESTUS" (ΗΦΑΙΣΤΟΣ) programme is continuing as planned, and all scheduled investments for production increase at EPALME and the Alumina production at the AoG plant are expected to be completed within the year. The production rate of Alumina and Recycled Aluminium will progressively be intensified with an expected record high in annual production for this year while expecting even higher quantities in 2022, with investments yielding for the whole year.

Sustainable Engineering Solutions Business Unit

2020 has been a turning point, as the former EPC & Infrastructure BU is being transformed, with new

organizational structure, focusing on projects that promote the goals of Energy Transition and Sustainable Development.

Hence, in addition to the construction of thermal power plants and selected construction projects traditionally executed by the BU, our activity is reinforced by the dynamic development of Sustainability projects:

For instance:

• solid & liquid waste management projects
• hybrid and off-grid energy projects
• energy upgrade projects
• execution of innovative first-of-kind energy projects (eg, hydrogen projects)

Aware of the international trends, MYTILINEOS is adapting its unique know-how to Sustainable Development Solutions and plans:

• a) To continue to deploy its competitive advantage in the construction of thermal units and to further develop in the field of Transmission & Distribution (T&D) and b) To grow targeted to the field of infrastructure through PPP projects and activities that require advanced know-how in view of the major projects that have been announced in our country within the relaunch of the economy in the post Covid-19 era.
• b) The Sustainable Engineering Solutions Business Unit focused on its strategic plan, is targeting in the growth its activities in countries with exceptional requirements, where its prestige and expertise places the SES BU in a prominent position internationally. The Company intends to utilize its significant financing prospects to create even greater added value for both its customers and its shareholders, wherever investment opportunities arise. The SES BU strategy aims to increase the backlog of 2021, by undertaking new projects and investments in targeted markets and focusing timely execution of current contracts. The planning and the prospects for each SES BU activity is summarized as follows:

• MYTILINEOS continues the construction of a new 826MW natural gas fired plant at its Energy Center in Agios Nikolaos, Viotia. Abroad, MYTILINEOS continues the construction of projects in Libya, Ghana, Nigeria and Slovenia. Having now gained a leading position in undertaking and execution of projects for the construction of natural gas-fired power plants, will be competing for new projects in Europe and Sub-Saharan Africa. MYTILINEOS, having the relevant experience, claims a significant market share for network energy transmission projects in Greece, Europe and Africa.

• The Business Unit will continue its efforts to undertake hybrid/off-grid projects, capitalizing on its relevant experience and knowledge from similar completed projects. Concurrently, it will continue the strategy implementation for the expansion and development of its presence in important energy saving and upgrade projects both in the Greek market and in selected foreign markets. Finally, it will intensify its presence in projects related to new technologies in combination with the provision of energy solutions, aiming at the development of new, diversified activities with added value for the Business Unit.

• MYTILINEOS holds a 7th class contractor degree in Greece and part of its business planning is the selective bidding of infrastructure projects, building, environmental and other projects, mainly within Greece, through construction contracts, PPP contracts or concession contracts.

• In the field on Environmental Solutions, MYTILINEOS sees great opportunities for growth based on the inferior expertise on circular economy solutions. In particular, in the field of waste-management, MYTILINEOS already has been recognized by the market as a large-scale "Turn-key" contractor. In addition to the under construction Protos ERF, an energy recovery facility of 400,000 tonnes of waste per year in the UK with and capacity of electricity production up to 49MW, MYTILINEOS has in line a series of similar projects, in which is in exclusive negotiations with clients.
• In addition to the large-scale Environmental projects, MYTILINEOS extends to the solid waste management through the development of biogas and waste management, where its selectively examines projects funding cases. In the field of sludge, liquid waste management and environmental remediation, it implements a plan for its systemic market penetration starting from Europe, Middle East and Africa, leveraging in the added value of subsidiary's exceptional expertise, ZEOLOGIC, which acts as a pioneering technological provider in this market. In this direction, a pilot unit for the management of liquid oil and chemical waste was concluded the current year, on the behalf of MYTILINEOS, in ZEOLOGIC's facilities.

Renewables & Storage Development

For the second semester of 2021, RSD will continue to focus on the timely execution of existing Third party EPC contracts and the undertaking of new projects and investments on selected markets with increased green energy needs.

Third party EPC Sub sector will continue the execution of already signed projects in Spain, Chile, Greece and Uzbekistan. Αt the same time RSD will focus on the signing of new projects that will renew its backlog, monitoring closely cost increases in the main equipment's of Solar projects combined with increased transportation costs.

More specifically in the first months of the second semester RSD will conclude with the signing of two new energy storage projects in UK for Gresham :

• Contracting and commencement of works of the Arbroath Energy Storage project of Gresham Hazel Llp (Energy Storage Accumulators with a total capacity of 35MWp) for a contract value of c. GBP 10 million in the United Kingdom.

• Contracting and commencement of works of the Coupar Energy Storage project of Gresham Hazel Llp (Energy Storage Accumulators with a total capacity of 40MWp) for a contract value of c.GBP 11 million in the United Kingdom. On top of the above projects there are also projects in Chile, UK, and Africa that are targeted to be signed within the second semester.

Finally, RSD will commence also the construction of MYTILINEOS own projects out of the portfolio of 1.5GW in Greece that were recently acquired from EGNATIA Group.

Regarding BOT projects, RSD will speed up the construction of its own projects in Cyprus, UK, Spain, Romania, Australia targeting to conclude them within 2022 and to proceed with the sale of selected projects. At the same time RSD will continue the development of the existing qualified projects that are at early stage and seek for new projects that will reinforce and renew its existing portfolio. RSD currently has under evaluation more than c. 2 GW of selected projects in different countries.

It is worth mentioning that within August, RSD will conclude its second major BOT transaction, similar to the successful sale of 47 MW in Greece that was concluded within the first semester of 2020. It is about two projects of total capacity of 91 MW in Romania that will be sold at development phase and will reach COD at the end of 2022.

As the portfolio of own projects reaches a mature stage, Own Development projects (BOT) becomes an activity that in the next years will have a significant contribution in the total financial performance of the RSD Business Unit.

Power and Gas Business Unit

MYTILINEOS, with approximately 1.4 GW installed thermal units and operating RES projects, while holding the leading position amongst the private energy suppliers, has established its position as the largest private vertically integrated electricity and NG company, reaching the critical size required in order to benefit the most out of the deregulation of the national electricity and NG market.

H2 2021 is expected to continue to be affected both by the extremely high prices of NG and CO2, as well as the special characteristics of the newly organized electricity market.

However, the financial results of the Power & Gas Business Unit are expected to be maintained at satisfactory levels due to:

• the access to competitive and flexible sources of Natural Gas supply, through direct contracts with large international producers and suppliers,
• the supply of LNG, where MYTILINEOS has a significant advantage over its competitors, due to its many years of experience and expanding network of suppliers,
• the efficient portfolio management of electric and NG energy, optimizing the total results,
• the increased capacity and the continuous expansion in the retail market supply of electricity and NG, while adjusting to the new market circumstances
• non-necessity of major maintenance of the Company's power plants
• the possible further de-lignification of the country's energy mix
• the increase of electricity consumption due to the recovery of economic activities.

2. Risks & Uncertainties

Financial risk management aims and policies

The Group's activities give rise to multiple financial risks, including the current and interest rate related risks; the volatility in market prices; credit risks and liquidity risks. The Group's risk management program aims at containing potential negative influence to its financial results, as this may arise from the inability to predict financial markets and the volatility with respect to cost and sales variables.

The essential risk management policies are determined by the Group's Management. The risk management policy is applied by the Corporate Treasury Department. The latter acts as a service centre, operating under specific Management - approved lines.

Credit Risk

The Group does not exhibit any considerable concentration of credit risk in any of the contracted parties. Credit risk originatesfrom available cash and cash equivalents, derivative financial instruments and deposits at banks and financial institutions; also from exposure to client derived credit risk.

Regarding commercial and other claims, the Group is not theoretically exposed to significant credit risks; as of the multifaceted nature of the Group's activities, there is no significant concentration of credit risk with respect to its commercial requirements, as this is allocated over a high number of clients. However, the atypical conditions that dominate the Greek market and several other markets in Europe are forcing the Group to constantly monitor its business claims and also to adopt policies and practices to ensure that such claims are collected. By way of example, such policies and practices include insuring credits where possible; pre-collection of the value of product sold to a considerable degree; safeguarding claims by collateral loans on customer reserves; and receiving letters of guarantee.

To minimize credit risk on cash reserves and cash equivalents; in financial derivate contracts; as well as other short term financial products, the Group specifies certain limits to its exposure on each individual financial institution and only engages in transactions with creditworthy financial institutions of high credit rating.

Liquidity Risk

Liquidity risk is related with the Group's need for the sufficient financing of its operations and development. The relevant liquidity requirements are the subject of management through the meticulous monitoring of debts of long term financial liabilities and also of payments made on a daily basis.

The Group ensures that there is sufficient available credit facilities to be able to cover its short-term business needs, after the calculation of cash flows arising from the operation as well as cash and cash equivalents which are held. The funds for long-term liquidity needs ensured by a sufficient amount of loanable funds and the ability to sell long-term financial assets.

Market risk

Price Risk

The Group's earnings are exposed to movements in the prices of commodities, which are determined by the international markets and the global demand and supply.

The Group faces price risk from fluctuations in the prices of variables that determine both the sales and the cost of sales of the group entities (i.e. products' prices (LME), raw materials, other cost elements etc.). The Group's activities expose it to the fluctuations of the prices of Aluminium (AL), Zinc (Zn), Lead (Pb) as well as to Fuel Oil as a production cost.

Regarding price fluctuation of metals, the Group's policy is to minimize risk by using financial derivative instruments.

Foreign Exchange Risk

The Group operates in a global level and consequently is exposed to foreign exchange risk emanating mainly from the US dollar. This kind of risk mainly results from commercial transactions in foreign currency as well as net investments in foreign entities. For managing this type of risk, the Group Treasury Department enters into derivative or nonderivative financial instruments with financial institutions on behalf and in the name of group companies.

At Group level, such financial instruments are considered to constitute compensation means for the exchange rate risk of specific assets, liabilities or future commercial transactions

Interest rate risk

The Group's assets that are exposed to interest rate fluctuation primarily concern cash and cash equivalents. The Group's policy as regards financial assets is to invest its cash in floated interest rates so as to maintain the necessary liquidity while achieving satisfactory return for its shareholders. In addition, for the totality of its bank borrowing, the Group uses floating interest rate instruments. Depending on the level of liabilities in floating interest rate, the Group proceeds to the assessment of interest rate risk and when necessary examines the necessity to use interest bearing financial derivative instruments. The Group's policy consists in minimizing its exposure to interest bearing cash flow risk as regards long-term funding.

COVID – 19 Risks

Mytilineos, as a responsible social partner and enterprise has expressed since the very beginning of the pandemic deep concern over the situation, the rapid spread of the virus and its effect on its operations but also on the economy and the broader society. The safety of company employees remains is the ultimate priority.

To that end, Mytilineos continues to implement during 1st half of 2021, the following initiatives through a special task force, (the "Task Force") that reports to senior management, monitoring all developments and assessing potential impacts of Covid-19.

The Task Force, adhering to all protocols from the WHO and other relevant authorities, has already put in place a business continuity plan which is currently in full implementation. Ιt has established and maintains clear internal and external protocols for regular and emergency communication with employees and other key stakeholders.

The actions of the Company, are presented in detail in the Annual Report of 2020.

3. Description of the main risks and management function of the Group in relation to the preparation of the financial statements

Framework of internal control systems and risk management function of the Company in relation to the preparation of the financial statements

The reliability of the Group's and Company's Financial Statements is ensured by the application of Internal Control and Risk Management Processes. The Company has put in place separate procedures for the monthly, interim and annual Financial Reports.

More specifically, every month the Management Information Systems Department of the Company receives from the Finance Business Partners financial data and information, which it proceeds to check and then use to prepare reports for submission to the Management of the Group. This information is produced in accordance with the International Financial Reporting Standards. Every month, the Management of the Group is updated on the changes to the consolidated key financial indicators by means of relevant management reports. This monthly monitoring approach, coupled with the checking of the consolidated financial statements and the analyses performed on the latter are the key tools used in the quality and consistency control of the financial results.

Regarding the Interim and Annual consolidated Financial Statements, the Company employs an advanced software tool to consolidate the financial results and statements, as well as to generate reports for the Management as well as for investors and other interested parties. This software tool is automatically updated with data from the Group's accounting monitoring program and includes controls to ensure accurate transfer and accounting recognition of the input data. The Management Information Systems Department ensures the smooth operation of the software tool and checks the integrity and correctness of the consolidated Financial Statements and other reports, providing the Chief Finance Officer, the External Auditors and the Management of the Company with all necessary information.

The External Auditors examine the consolidated Interim and Annual Financial Reports and report to the Audit Committee on the progress and results of their audits for each reporting period. The Audit Committee is informed of the procedure and schedule for the preparation of the Financial Statements by the Group Chief Finance Officer and holds meetings with the Management / the responsible executives during the preparation of the financial reports. It obtains from the Chief Finance Officer the necessary information on the Group's performance and consolidated Financial Statements and reports to the Board of Directors accordingly. During these meetings, the Audit Committee is also informed about the management of financial risks and assesses the effectiveness of the risk management system. The Financial Statements (Individual and Consolidated) are approved by the Board of Directors, following a relevant report from the Audit Committee.

Organisation and implementation of risk management

The Company has defined risk as a set of uncertain and unpredictable situations that may affect all its activities, its business operation and its financial performance, as well as the implementation of its strategy and the achievement of its goals.

In line with this approach, it has established a specific risk management approach in all its areas of activity where certain risks have been recognised. This approach consists of the following steps:

• Identification and assessment of risk factors.
• Planning of the risk management policy.
• Implementation and evaluation of the risk management policy.

The Company has established specific and comprehensive Enterprise Risk Management (ERM) processes. All senior executives are involved in the identification and initial assessment of risks, so as to facilitate the work of the Executive Committees of each Business Unit, as well as of the Board of Directors of each legal person, in the planning and approval of specific actions in the context of the approved ERM processes.

With regard to Non-Financial Information, since 2010 the Company has introduced a specific Stakeholder engagement process for evaluating the materiality of the sustainability issues which are related to its activity sectors. This process, combined with the corresponding prioritisation of these issues by the Company's Business Units, is at the core of the accountability policy applied by the Company.

The process for determining the material sustainability issues is an ongoing exercise that is constantly developed and improved. The purpose of this process is to highlight the issues that reflect the Company's significant environmental and social impacts and influence substantially the decisions of its Stakeholders.

By identifying and understanding the material sustainability issues, the Company formulates and develops its uniform business strategy and its aims, targets and social and environmental initiatives.

Finally, the Company conducts regular internal audits to ensure the appropriate and effective implementation of the risk identification and assessment processes and of the management policies for such risks.

Internal Control System

1. In addition to everything mentioned herein and described above in connection with the competences of the Audit Committee, the Internal Audit Division of the Company is an independent organisational unit which reports to the Board of Directors. Its competences include, among others, the assessment and improvement of the risk management and internal control systems, as well as the monitoring of the compliance with the established policies and procedures as these are determined by the Internal Regulations of Operation, the legislation in force and the regulatory provisions.

Moreover, the following are examined and analysed on a continuous basis:

• The efficiency of the Company's accounting and financial systems, audit mechanisms, quality control systems, health & safety and environmental systems, and business risk management systems.

• The drafting of the financial statements and of other important data and information intended for disclosure.

• The reliability, the qualifications and the independence of the chartered auditors.

• Cases of conflict between the private interests of the members of the Board or executives of the Company and the latter's interests.

• Relations and transactions of the Company with affiliated companies as well as relations of the Company with companies in whose share capital members of the Company's Board of Directors participate with a percentage of at least 10% or shareholders of the Company participate with a percentage of at least 10%.

• The legality of the fees and any kind of bonuses to the members of the management with regard to the decisions of the competent bodies of the Company.

• The Board of Directors re-examines in a continuous and consistent way the corporate strategy and the principal business risks, especially in a constantly changing financial and business environment. Moreover, the Board receives at regular intervals from the Audit Committee reports on the activities of the audits carried out, based on the annual schedule of audits planned by the Company's Internal Audit Department. The above allow the Board to form a detailed opinion of the effectiveness of the systems, processes and regulations of the Company.

• The external auditors do not offer to the Company and to the Group non-audit services which are prohibited, as per the provisions article 5 of Regulation (EU) 537/2014 of the European Parliament and of the Council and of law 4449/2017.

C. Independent Auditor's Report

To the Board of Directors of "MYTILINEOS S.A."

Report on Review of Interim Financial Information

Introduction

We have reviewed the accompanying interim condensed separate and consolidated statement of financial position of the Company "MYTILINEOS S.A." as of 30 June 2021 and the related condensed separate and consolidated income statements and statements of other comprehensive income, statements of changes in equity and cash flows for the six-month period then ended, and the selected explanatory notes that constitute the interim condensed financial information, which forms an integral part of the six-month financial report according to Law 3556/2007. Management is responsible for the preparation and presentation of this interim condensed financial information, in accordance with International Financial Reporting Standards, as adopted by the European Union and which apply to Interim Financial Reporting (International Accounting Standard IAS 34). Our responsibility is to express a conclusion on this interim condensed financial information 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 to 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

Our review, has not revealed any material inconsistency or misstatement in the statements of the members of the Board of Directors and the information of the six-month Board of Directors Report, as defined under article 5 and 5a of Law 3556/2007, in relation to the accompanying interim condensed separate and consolidated financial information.

7. Additional Information

7.1 Basis for preparation of the financial statements

The interim condensed consolidated financial statements as of 30 June 2021 (hereinafter referred to as the "financial statements") have been prepared in accordance with the International Financial Reporting Standards (IFRS) as adopted by the European Union, and in particular, in accordance with the provisions of IAS 34 Interim Financial Statements". No Standards have been applied prior to the date of their application. Moreover, the financial statements have been prepared based on the historical cost principle as amended by adjusting specific assets and liabilities to present values, the going concern principle and are in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB) and their interpretations as issued by the IASB Interpretation Committee (IFRIC).

The accounting policies, under which the accompanying Interim Condensed Financial Statements are prepared, are in compliance with those used for the preparation of the annual Financial Statements for FY 2020 and have been consistently applied for all the presented years.

In May 2021, the International Financial Reporting Interpretations Committee ("the Committee") issued the final agenda decision under the title "Attributing Benefits to Periods of Service" (IAS 19), which includes explanatory material regarding the way of distribution of benefits in periods of service following a specific defined benefit plan proportionate to that defined in Article 8 of Law 3198/1955 regarding provision of compensation due to retirement (the "Labor Law Defined Benefit Plan").

In particular, the aforementioned final decision of the Committee's agenda provides explanatory information on the application of the basic principles and regulations of IAS 19 in respect of the distribution of benefits in periods of service similar to that of the Labor Law Defined Benefit Plan. This explanatory information differentiates the way in which the basic principles and regulations of IAS 19 have been applied in Greece in the previous years, and therefore, according to what is defined in the "IASB Due Process Handbook (par 8.6)", entities that prepare their financial statements in accordance with IFRS are required to amend their Accounting Policy accordingly.

Based on the above, the aforementioned final decision of the Committee's agenda will be treated as a Change in Accounting Policy. The aforementioned decision will be implemented in accordance with paragraphs 19-22 of IAS 8. The change in accounting policy will be applied retrospectively with a corresponding adjustment of the opening balance of every affected equity item for the older of the presented periods and other comparative amounts for every prior period presented as if the new accounting policy had always been effective. The requirements of IAS 8 on disclosures in cases of Changes in Accounting Policies should be applied accordingly. The validity of the above final decision of the Committee's agenda is of immediate effect.

The Group and the Company have proceeded with the preparation of an implementation plan of the change in the aforementioned accounting policy with the date of completion of the plan to be determined by the end of the year, in order to reflect the impact on the annual financial statements for the year ending December 31, 2021. At this stage, it is not possible to accurately determine the expected effect arising from the change in the aforementioned accounting policy.

Discontinued Operations

The Company Mytilineos S.A. which resulted from the merger of its subsidiaries METKA, ALUMINUM OF GREECE, PROTERGIA and PROTERGIA THERMO AGIOS NIKOLAOS presents separately the result from discontinued operations as described below.

In 2009, applying IFRS 5 "Non-current assets held for sale & discontinued operations", the assets and liabilities of the subsidiary company SOMETRA S.A. were presented separately, regarding which a decision was made on January 26, 2009 on temporary suspension of the production activity of the Zinc-Lead production plant in Romania, and presents also the amounts recognized in the income statement separately from continuing operations. Given the global economic recession, there were no feasible scenarios for the alternative utilization of the aforementioned financial assets.

Consequently, since 2011, by applying par. 13 of IFRS 5 "Non-current assets Held for Sale" Zinc-Lead («SOMETRA S.A.») production ceases to be an asset held for sale and is considered as an asset to be abandoned. The assets of its operations returned to continuing operations while at the same time, it continued to show separately the result of the discontinued operation in the income statement.

On 31/12/2015, SOMETRA S.A., contributed the Zinc-Lead activity, through a spin – off process, to its newly established subsidiary Reycom Recycling S.A. (REYCOM). The said spin - off is part of the "Mytilineos Group" restructuring process, regarding the Zinc-Lead discontinued operation, targeting on the production of Zn & Pb oxides through the

development of a recycling operation of metallurgical residues. Within the same frame, on 29/11/2016 the crossborder merger of the subsidiary REYCOM and the subsidiary company ALUMINUM OF GREECE (ATE) was completed.

7.2.1 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 01/01/2021.

Amendments to IFRS 4 "Insurance Contracts" – deferral of IFRS 9 (effective for annual periods starting on or after 01/01/2021)

In June 2020, the IASB issued amendments that declare deferral of the date of initial application of IFRS 17 by two years, to annual periods beginning on or after January 1, 2023. As a consequence, the IASB also extended the fixed expiry date for the temporary exemption from applying IFRS 9 "Financial Instruments" in IFRS 4 "Insurance Contracts", so that the entities are required to apply IFRS 9 for annual periods beginning on or after January 1, 2023.

The amendments do not affect the consolidated and separate Financial Statements.

Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16: " Interest Rate Benchmark Reform – Phase 2" (effective for annual periods starting on or after 01/01/2021)

In August 2020, the IASB has finalized its response to the ongoing reform of IBOR and other interest benchmarks by issuing a package of amendments to IFRS Standards. The amendments complement those issued in 2019 and focus on the effects on financial statements when a company replaces the old interest rate benchmark with an alternative benchmark rate as a result of the reform. More specifically, the amendments relate to how a company will account for changes in the contractual cash flows of financial instruments, how it will account for a change in its hedging relationships as a result of the reform, as well as relevant information required to be disclosed.

The amendments do not affect the consolidated and separate Financial Statements.

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

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 IFRS 3 "Business Combinations", IAS 16 "Property, Plant and Equipment", IAS 37 "Provisions, Contingent Liabilities and Contingent Assets" and "Annual Improvements 2018-2020" (effective for annual periods starting on or after 01/01/2022)

In May 2020, the IASB issued a package of amendments which includes narrow-scope amendments to three Standards as well as the Board's Annual Improvements, which are changes that clarify the wording or correct minor consequences, oversights or conflicts between requirements in the Standards. More specifically:

• Amendments to IFRS 3 Business Combinations update a reference in IFRS 3 to the Conceptual Framework for Financial Reporting without changing the accounting requirements for business combinations.
• Amendments to IAS 16 Property, Plant and Equipment prohibit a company from deducting from the cost of property, plant and equipment amounts received from selling items produced while the company is preparing the asset for its intended use. Instead, a company will recognize such sales proceeds and related cost in profit or loss.
• Amendments to IAS 37 Provisions, Contingent Liabilities and Contingent Assets specify which costs a company includes when assessing whether a contract will be loss-making.
• Annual Improvements 2018-2020 make minor amendments to IFRS 1 First-time Adoption of International Financial Reporting Standards, IFRS 9 Financial Instruments, IAS 41 Agriculture and the Illustrative Examples accompanying IFRS 16 Leases.

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 effective date of 01/01/2022.

Amendments to IFRS 16 "Leases": Covid-19 – Related Rent Concessions beyond 30 June 2021 (effective for annual periods starting on or after 01/04/2021)

In March 2021, the IASB issued amendments to the practical expedient of IFRS 16, that extend the application period by one year to cover Covid-19-related rent concessions that reduce only lease payments due on or before 30 June 2022. The Group 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.

IFRS 17 "Insurance Contracts" (effective for annual periods starting on or after 01/01/2023)

In May 2017, the IASB issued a new Standard, IFRS 17, which replaces an interim Standard, IFRS 4. The aim of the project was to provide a single principle-based standard to account for all types of insurance contracts, including reinsurance contracts that an insurer holds. A single principle-based standard would enhance comparability of financial reporting among entities, jurisdictions and capital markets. IFRS 17 sets out the requirements that an entity should apply in reporting information about insurance contracts it issues and reinsurance contracts it holds. Furthermore, in June 2020, the IASB issued amendments, which do not affect the fundamental principles introduced when IFRS 17 has first been issued. The amendments are designed to reduce costs by simplifying some requirements in the Standard, make financial performance easier to explain, as well as ease transition by deferring the effective date of the Standard to 2023 and by providing additional relief to reduce the effort required when applying the Standard for the first time. The Group does not expect to have any impact of the above on its Financial Statements. The above have not been adopted by the European Union.

Amendments to IAS 1 "Classification of Liabilities as Current or Non-current" (effective for annual periods starting on or after 01/01/2023)

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. The Group 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 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 the financial statements. More specifically, companies are required to disclose their material accounting policy information rather than their significant accounting policies. The Group 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 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 they 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 Group 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 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 Group 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.

7.3 Significant accounting judgments, estimates and assumptions

Preparations of financial statements under IFRS requires the management to apply judgments, make estimates and use assumptions that affect publisized amounts of assets and liabilities as well as disclosures of contingent assets and liabilities as at the financial statements preparation date and publicized amounts of revenue and expenses for the reporting period. The actual results may differ from estimated.

Estimations are reassessed on an on-going basis and are based on both – past experience and other factors, such as expectations of future events deemed reasonable under the current conditions.

Change in accounting policies

On 01/01/2021, the Group decided to change the useful life of natural gas-powered plants. Specifically, the remaining useful life of power plants was adjusted to 35 years from 30 years in which it was initially estimated. The reasons for that estimation are:

• There is experience of at least 10 years from the operation of power plants. These power plants have had a good performance during these years and the maintenance cost hasn't increased. The availability of the power plants, ranges at levels above 95% while their reliability is close to 100%, because of the reliability of the manufacturers and the right maintenance, during their operation.
• Following decarbonization of the energy market, the natural gas-powered plants have already started to occupy the share of the withdrawn lignite units in the market, being the main units of electricity production both at peak hours and at the hours during which the RES do not produce.
• The critical role of power plants to stabilize and secure the energy system, due to the ever-increasing penetration of Renewable Energy Sources (RES), especially since there is no other more technically reliable and cost-effective solution, combined with exceptional reliability and the high-cost construction of a new natural gas power plant, contribute to their operation for at least 35 years.

The Management assessed the change in accounting estimate as realistic. The Group changed this accounting estimate of useful life, using the provisions of IAS 8 "Accounting Policies, Changes in Accounting Estimates and Errors" by estimating that the rate of future benefits of fixed assets has changed and adjusting accordingly the depreciation rate to reflect the new rate. The positive effect of the change in accounting estimate for the period 01/01/2021 – 30/06/2021 amounted to 2,509 thousands and affected the tangible, intangible assets and results of the Group for the same period.

On 01/01/2021, the Group altered the useful life of the capitalized association commissions of the retail partners in the Electricity and Natural Gas Segment, which are in charge of attracting customers. Specifically, the useful life was adjusted to 3 years versus 2 years, at which it was initially estimated. The reason behind it is that nowadays, statistics show that the average customer is represented by electricity and gas supply companies in a three-year period.

Management assesses the change in accounting estimate as completely realistic. The Group changed this accounting estimate of useful life, using the provisions of IAS 8 "Accounting Policies, Changes in Accounting Estimates and Errors", estimating that the rate of future benefits incorporated in the specific fixed assets changed, respectively adapting the amortization rate, so that it should reflect the newly formed rate. The positive effect arising from the change in the accounting estimate for 01/01/2021-30/06/2021 stood at € 1,052 thousand and affected the intangible assets and the Group results for the reporting period.

7.4 Pro forma figure "Operating Earnings before Financial & Investment results, Tax, Depreciation & Amortization" (Group EBITDA)

Pro forma figures (EBITDA, EBITDA margin, free cash flow, net debt) are not defined by the International Financial Reporting Standards (IFRS). Thus, these figures are calculated and presented by the Group in a way that provides a more fair view of the financial performance of its Business Sectors. The Group defines "Group EBITDA" as the Operating earnings before any interest income and expenses, investment results, depreciation, amortization and before the effects of any special factors. "Group EBITDA" is an important indicator used by Mytilineos Group to manage the Group's operating activities and to measure the performance of the individual segments.

The special factors that affect the Group's net profit / (losses) and EBITDA are the following:

a) the share in the EBITDA of associates when these are active in one of the Group's reported Business Sectors and b) the effects of eliminations of any profit or loss from asset construction transactions of the Group with the associates.

It is noted that the Group financial statements, prepared according to IAS 1 and IAS 28, include the Group's profit realized in connection with the construction of fixed assets on account of subsidiaries and associates, when these are active in one of its reported Business Segments. Such profits are deducted from the Group's equity and fixed assets and released in the Group accounts over the same period as depreciation is charged. Consequently, for the calculation of EBITDA (operational results before depreciation), the Group does not eliminate the profit from the construction of fixed assets as its recovery through their use will effect only the profit after depreciation.

The Group states that the calculation of "Group EBITDA" may differ from the calculation method used by other companies/groups. However, "Group EBITDA" is calculated with consistency in each financial reporting period and any other financial analysis presented by the Group. Specifically financial results contain interest income/expense, while investment results contain gains/loss of financial assets at fair value through profit and loss, share of results in associates companies and gains/losses from the disposal of financial assets (such as subsidiaries and associates).

The Group's service lines that do not fulfil the quantitative and qualitative thresholds of IFRS 8, in order to be considered as separate segments, are presented cumulatively under the category "Others".

The totals that are presented in the following tables, reconcile to the related accounts of the consolidated financial statements.

7.17 Fair Value Measurements

The following table presents financial assets and liabilities measured at fair value in the statement of financial position in accordance with the fair value hierarchy. This hierarchy groups financial assets and liabilities into three levels based on the significance of inputs used in measuring the fair value of the financial assets and liabilities. The fair value hierarchy has the following levels:

• Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities;

• Level 2: inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices); and

• Level 3: inputs for the asset or liability that are not based on observable market data (unobservable inputs).

The level within which the financial asset or liability is classified is determined based on the lowest level of significant input to the fair value measurement.

The Group's financial assets and liabilities measured at fair value in the statement of financial position are grouped into the fair value hierarchy for 30/06/2021 and 31/12/2020 as follows:

7.18 Risks and uncertainties

Financial risk management aims and policies

The Group's activities give rise to multiple financial risks, including the current and interest rate related risks; the volatility in market prices; credit risks and liquidity risks. The Group's risk management program aims at containing potential negative influence to its financial results, as this may arise from the inability to predict financial markets and the volatility with respect to cost and sales variables.

The essential risk management policies are determined by the Group's Management. The risk management policy is applied by the Corporate Treasury Department. The latter acts as a service centre, operating under specific Management - approved lines.

Credit Risk

The Group does not exhibit any considerable concentration of credit risk in any of the contracted parties. Credit risk originatesfrom available cash and cash equivalents, derivative financial instruments and deposits at banks and financial institutions; also from exposure to client derived credit risk.

Regarding commercial and other claims, the Group is not theoretically exposed to significant credit risks; as of the multifaceted nature of the Group's activities, there is no significant concentration of credit risk with respect to its commercial requirements, as this is allocated over a high number of clients. However, the atypical conditions that dominate the Greek market and several other markets in Europe are forcing the Group to constantly monitor its business claims and also to adopt policies and practices to ensure that such claims are collected. By way of example, such policies and practices include insuring credits where possible; pre-collection of the value of product sold to a considerable degree; safeguarding claims by collateral loans on customer reserves; and receiving letters of guarantee.

To minimize credit risk on cash reserves and cash equivalents; in financial derivate contracts; as well as other short term financial products, the Group specifies certain limits to its exposure on each individual financial institution and only engages in transactions with creditworthy financial institutions of high credit rating.

Liquidity Risk

Liquidity risk is related with the Group's need for the sufficient financing of its operations and development. The relevant liquidity requirements are the subject of management through the meticulous monitoring of debts of long term financial liabilities and also of payments made on a daily basis.

The Group ensures that there is sufficient available credit facilities to be able to cover its short-term business needs, after the calculation of cash flows arising from the operation as well as cash and cash equivalents which are held. The

funds for long-term liquidity needs ensured by a sufficient amount of loanable funds and the ability to sell long-term financial assets.

Market risk

Price Risk

The Group's earnings are exposed to movements in the prices of commodities, which are determined by the international markets and the global demand and supply.

The Group faces price risk from fluctuations in the prices of variables that determine both the sales and the cost of sales of the group entities (i.e. products' prices (LME), raw materials, other cost elements etc.). The Group's activities expose it to the fluctuations of the prices of Aluminium (AL), Zinc (Zn), Lead (Pb) as well as to Fuel Oil as a production cost.

Regarding price fluctuation of metals, the Group's policy is to minimize risk by using financial derivative instruments.

Foreign Exchange Risk

The Group operates in a global level and consequently is exposed to foreign exchange risk emanating mainly from the US dollar. This kind of risk mainly results from commercial transactions in foreign currency as well as net investments in foreign entities. For managing this type of risk, the Group Treasury Department enters into derivative or nonderivative financial instruments with financial institutions on behalf and in the name of group companies.

At Group level, such financial instruments are considered to constitute compensation means for the exchange rate risk of specific assets, liabilities or future commercial transactions

Interest rate risk

The Group's assets that are exposed to interest rate fluctuation primarily concern cash and cash equivalents. The Group's policy as regards financial assets is to invest its cash in floated interest rates so as to maintain the necessary liquidity while achieving satisfactory return for its shareholders. In addition, for the totality of its bank borrowing, the Group uses floating interest rate instruments. Depending on the level of liabilities in floating interest rate, the Group proceeds to the assessment of interest rate risk and when necessary examines the necessity to use interest bearing financial derivative instruments. The Group's policy consists in minimizing its exposure to interest bearing cash flow risk as regards long-term funding.

COVID – 19 Risks

Mytilineos, as a responsible social partner and enterprise has expressed since the very beginning of the pandemic deep concern over the situation, the rapid spread of the virus and its effect on its operations but also on the economy and the broader society.

The Group, since 2009, applies IFRS 5 "Non-current assets held for sale & discontinued operations", and presents separately the assets and liabilities of the subsidiary company SOMETRA S.A., following the suspension of the production activity of the Zinc-Lead production plant in Romania, and presents also the amounts recognized in the income statement separately from continuing operations. Given the global economic recession, there were no feasible scenarios for the alternative utilization of the aforementioned financial assets.

From 2011 and on, by applying par. 13 of IFRS 5 "Non-current assets Held for Sale", the Zinc-Lead production ceases to be an asset held for sale and is considered as an asset to be abandoned. The assets of the disposal group to be abandoned are presented within the continuing operations while the results as discontinued operations.

In December 2015, SOMETRA S.A., contributed the Zinc-Lead activity, through a spin – off process, to its newly established subsidiary Reycom Recycling S.A. (REYCOM). The said spin - off is part of the "Mytilineos Group" restructuring process, regarding the Zinc-Lead discontinued operation, targeting on the production of Zn & Pb oxides through the development of a recycling operation of metallurgical residues.

The aforementioned tax audits are in progress.

7.31 Other Contingent Assets & Liabilities

Extraordinary contribution of 6% for High Efficiency Cogenration of Heat and Power plant.

According to the informatory notes sent by the societe anonyme named Renewable Energy Sources Operator and Guarantees of Origin (DAPEEP SA) on 01.02.2019 to the Company, an extraordinary contribution was imposed upon the total income of electricity quantities injected to the transmission system from the High-Efficiency Cogeneration of Heat and Power (CHP) plant of the of Metallurgy Business Unit.

From the interpretation of the relevant law provision (article 157 of law 4579/2020), taking also into consideration the parliament's explanatory memorandum, results, that legally, regulatory and economically- technically, it is correct and reasonable to calculate this extraordinary contribution exclusively on the part of the income (turnover) of the dispatched electricity quantities from τηε CHP plant which is paid by DAPEEP and concerns the special account for renewable energy sources (ELAPE), and not for the part of the generated electricity, which relates to the wholesale electricity market and is invoiced to the societe anonyme Hellenic Energy Exchange SA (HEnEx). The amount disputed by the Company amounts to [1.9] million Euro.

The Company filed an appeal before the administrative courts against the Greek State and DAPEEP for the annulment of the informatory note for the extraordinary contribution of article 157 of law 4759/2020. In addition, the Company intends refer also to Greek civil courts in order to obtain a judiciary acknowledgement that DAPEEP, contrary to contract and the law, charged the Company with the said contribution on the total income from the production of the CHP plant. The positive outcome of the above cases is contemplated by the Company.

Dispute with the company IMERIS Bauxites (former ELMIN Bauxites)

Since 2017, the Company has been in dispute with IMERIS Bauxites (hereinafter IB) before the Hellenic Competition Commission (HCC), following a Company's complaint for abuse of a dominant position. The procedure before the Commission was completed in June 2021, the final memoranda will be submitted on 11.08.2021 and the decision is expected to be issued within 2021. At the same time, a new complaint was filed by the Company in April 2021, the examination of which is pending.

The commercial relationship between the two companies is regulated since 2017 until the end of 2019, by temporary agreements dictated by interventions and a decision on precautionary measures of the HCC. For the years 2020 and 2021 IB has been invoicing the Company without an agreement with the latter, and the Company disputes the above invoicing, as it considers that it does not correspond to a reasonable and worthy price for the supply of such metallurgical bauxite. Consequently, the Company registers in its books and pays for the delivered quantities at the price agreed under the latest contract, which coincides with that of a decision of precautionary measures issued in the past by the HCC.

In May 2021, the Company filed an application for interim measures before the civil courts, accompanied by a request for an interim injunction, which (interim injunction) was granted and temporarily orders IB to monthly supply of the Company as a priority with a monthly quantity of 45,000 MT for standard quality bauxite, i.e. at the price at which the Company pays the delivered quantities, according to the aforementioned. IB filed an application for revocation of the interim injunction, which was rejected. The hearing for the above application for interim measures of the Company has been set for 20.09.2021 and the issuance of a decision is expected within the year 2021. Finally, IB, on 08.07.2021, ie after the issuance of the temporary injunction temporarily ordering ΙΒ to provide the Company per month with a quantity of 45,000 MT for standard quality bauxite at the price at which the Company repays the delivered quantities according to the above, filed a lawsuit before civil courts claiming the amount of 5,073,424 euro plus interest, for the difference between invoiced and amounts actually paid according to the aforementioned for the period 2020-May 2021.

Petitions for annulment of Regulatory Authority for Energy (RAE) decisions – CHP plant

The Company filed before the Council of State: (a) petition for annulment of RAE's decision no. 80/2016 entitled "Management of condensate heat during the calculation of cogeneration efficiency for the Approval of Special Operating Conditions of CHP plant"; and (b) petition for annulment of RAE's decision no 410/2016 entitled "Amendment of RAE's decision no. 1599/201, with which it was approved the Issue "Cash Specifications and Size Measurements at the request of the ministerial decision no Δ6 / Φ1 / οικ.8786 / 06.05.2010 for the implementation of the System of Guarantees of Origin of the Electricity from RES and High Efficiency CHP and its Ensuring Mechanism".

The Company also filed before the Athens Administrative Court of Appeal a petition for annulment of RAE's decision no. 334/2017 entitled "On the application of the societe anonyme ALUMINUM OF GREECE BEAE and the distinctive title "ΑΤΕ" for the revision of RAE's decision no. 569/2016"; (b) of RAE's decision no. 569/2016 entitled "Efficiency Control and Determination of Special Operating Conditions of the Distributed HE-CHP unit of the societe anonyme ALUMINUM OF GREECE BEAE (SA)".

From the combination of the above decisions, the cogeneration efficiency of the CHP plant of the Metallurgy Business Unit is negatively affected, as they change the calculation method for the amount of high efficiency electricity, including by subtracting the thermal energy contained in returnable concentrate, when calculating the total efficiency of the unit, resulting in a reduction in unit revenue.

The decisions of the Council of State were issued, according to which the Company's petitions for annulment have been rejected. However, due to the reasoning of the Council of State decisions, the positive outcome of its petition for annulment before the Athens Administrative Court of Appeal is contemplated by the Company.

Company's other Contingent Assets & Liabilities

In May 2020 the Consortium consisting of the companies "General Electric International Inc." and "Mytilineos S.A." (formerly METKA SA), in its capacity as EPC Contractor of the project "HASSI R'MEL I - Construction and commissioning of a power plant with a total capacity of 368,152 MW in Algeria", (hereinafter "the Project") referred to the International Chamber of Commerce (ICC) against the company and the owner of the project under the name "Société Algérienne de Production de l'Electricité" (SAPE), for claims due to delays of the Project, which fall within the sphere of responsibility of the project owner. The Company will recognize in its results the amount that may be awarded to it at the time of the positive outcome of this arbitration procedure. Respectively, the project owner has raised, in the context of his response to the request for arbitration, counterclaims. According to the assessment of the legal advisors of the Company the aforementioned counterclaims of the project owner are unlikely to succeed.

According to IAS 37.14: A provision shall be recognised when: (a) an entity has a present obligation (legal or constructive) as a result of a past event; (b) it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation; and (c) a reliable estimate can be made of the amount of the obligation. If these conditions are not met, no provision shall be recognised. Therefore: a) an entity has a present obligation as a result of project owner's counterclaim, b) the possibility of success is extremely low and the outflow of resources to settle the obligation is not probable, c) no reliable estimation can be made regarding this obligation.

There are other potential third party claims of € 2.6 Mio against the Company for which no provision has been made. According to IAS 37.14: A provision shall be recognised when: (a) an entity has a present obligation (legal or constructive) as a result of a past event; (b) it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation; and (c) a reliable estimate can be made of the amount of the obligation. If these conditions are not met, no provision shall be recognised. No provision has been made for this matter, since according to the relevant opinions of the Company's legal advisers and the management of the Company: (a) the existence of a commitment has not yet been finalized; and (b) there is no probability that there will be an outflow of financial resources.

Moreover, there are claims of the Company against third parties, which totally amount to €0.03 Mio.

Guarantees

Apart from the above mentioned parent company guarantees in note 7.25, there are € 467.25 mio Group guarantees and € 437.08 mio parent company guarantees to customers and suppliers.

7.32 Income Tax

The change (reduction) of the deferred tax receivables in Group and Company, due to the effect of the reduction of the tax rate from 24% to 22% for the year 2021, amounts to € 2.8 million and € 4.49 million respectively.
