1. ORGANIZATION AND OPERATIONS OF THE GROUP

Mardin Çimento Sanayii ve Ticaret A.Ş. ("Mardin Çimento"), was established on June 2, 1969 under the leadership of Türkiye Çimento Sanayii Türk Anonim Şirketi. The assembly of the factory was completed in 1975 and production started in September 1975.

OYAK Çimento A.Ş. ("OYAK Çimento"), which was established on November 25, 2015 as a 100% subsidiary of the Ordu Yardımlaşma Kurumu ("OYAK") took over the shares of Mardin Çimento owned by OYAK on December 3, 2015 and OYAK Çimento became the main shareholder of the Company. On November 26, 2018, OYAK transferred 40% of its 100% owned OYAK Cement shares to TCC Group Holdings ("TCC").

Founded in 1946 and restructured as a joint-stock company in 1951, TCC operates in the fields of cement and ready-mix concrete production, renewable energy, energy storage, high-efficiency battery manufacturing, and carbon black production. TCC's shares have been listed on the Taiwan Stock Exchange since February 1962.

OYAK is an institution that is financially and administratively autonomous, which has a legal personality, subject to private law provisions, and was established on March 1, 1961 with the law numbered 205. OYAK, the "solidarity and pension fund" of TAF members, provides various services and benefits to its members. OYAK has more than 50 direct and indirect subsidiaries operating in the industry, finance and service sectors.

Due to the purposes of providing more effective management, creating a strong financial, administrative and legal structure in the operating sector and strengthening the production and distribution activities; merger process has been started for Aslan Çimento A.Ş. ("Aslan Çimento"), Adana Çimento Sanayii Türk A.Ş. ("Adana Çimento"), Bolu Çimento Sanayii A.Ş. ("Bolu Çimento") and Ünye Çimento Sanayi ve Ticaret A.Ş. ("Ünye Çimento") following the application to Capital Market Boards in accordance with the board of directors decisions dated December 30, 2019. As of February 20, 2020, the merger application is approved and published in Capital Markets Board bulletin. The general assembly regarding the merger was held on March 27, 2020 and the merger was approved by the shareholders. The process of retirement right within the scope of merger started on April 6, 2020 and ended on May 5, 2020. With the registration of the General Assembly Resolutions for the merger on May 14, 2020, the legal process for the merger was completed. Following the merger, the title of Mardin Çimento was changed to OYAK Çimento Fabrikaları A.Ş. ("The Company") on May 21, 2020.

As of December 31, 2020, OYAK Beton San. ve Tic. A.S. ("OYAK Beton") one of the subsidiaries of the Company, merged within OYAK Çimento Fabrikaları A.Ş. together with all its assets and passives.

On June 13, 2023, the Company's parent's title was changed from OYAK Çimento A.Ş. to OYAK Denizli Çimento A.Ş. Subsequently, Denizli Çimento Sanayii Türk A.Ş. one of the subsidiaries of the parent, was merged and registered within the parent as of June 19, 2023, by applying the "facilitated merger" method, together with all its assets and liabilities.

By evaluating the synergy that will be created by the economic and operational advantages of the merger, the opportunities that will be created by the size of the Company that will emerge after the merger, and the benefits it will provide to all shareholders, an application was made to the Capital Markets Board pursuant to the Board of Directors' Decision dated September 11, 2023, for the Company's merger with OYAK Denizli Çimento A.Ş., its main shareholder, under the roof of the Company by taking over it as a whole together with its assets and liabilities, and the application was approved on November 22, 2023. At the Extraordinary General Assembly meeting dated December 25, 2023 regarding the merger, the Company "took over" OYAK Denizli Çimento Anonim Şirketi as a whole with all its assets and liabilities, and the merger within the Company was accepted by the shareholders. The merger transaction has been registered on December 28, 2023.

As a result of the merger, Cimpor Global Holdings B.V., which was the 100% shareholder of the former OYAK Denizli Çimento A.Ş. ("CGH") became the parent of OYAK Çimento Fabrikaları A.Ş. with a share of 75.81%.

2. BASIS OF PRESENTATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (cont'd)

2.1 Basis of Presentation (cont'd)

Adjustment of consolidated financial reporting in hyperinflationary economy (cont'd)

According to the standard, financial statements prepared using the currency of a hyperinflationary economy are presented in terms of the purchasing power of that currency at the balance sheet date. Prior period financial statements are also presented in terms of the current measurement unit at the end of the reporting period for comparative purposes. The Group has therefore presented its consolidated financial statements as of December 31, 2024 and September 30, 2024, on the purchasing power basis as of September 30, 2025.

According to the decision numbered 81/1820 dated December 28, 2023, by the Capital Markets Board (CMB), issuers and capital market institutions subject to the Turkish Accounting/Financial Reporting Standards are required to apply the provisions of TAS 29 starting from the annual financial reports for the accounting periods ending as of December 31, 2023, in order to implement inflation accounting.

The adjustments made in accordance with TAS 29 were made using the adjustment coefficient obtained from the Consumer Price Index (CPI) of Turkey published by the Turkish Statistical Institute (TÜİK). As of September 30, 2025, the indices and adjustment coefficients used in the adjustment of the consolidated financial statements are as follows:

Date Index Index (%) Conversion factor
September 30, 2025 3367,22 33,29 1,00000
December 31, 2024 2684,55 44,38 1,25430
September 30, 2024 2526,16 49,38 1,33294

The main components of the Group's adjustments for financial reporting in hyperinflationary economies are as follows:

  • a) Current period consolidated financial statements prepared in Turkish Lira (TL) are expressed in terms of the purchasing power at the balance sheet date, and amounts from previous reporting periods are also adjusted and expressed according to the purchasing power at the end of the reporting period.
  • b) Monetary assets and liabilities are not adjusted as they are already expressed in terms of the current purchasing power on the balance sheet date. If the inflation-adjusted values of nonmonetary items exceed their recoverable amount or net realizable value, the provisions of TAS 36 "Impairment of Assets" and TAS 2 "Inventories" are applied, respectively.
  • c) Non-monetary assets and liabilities, as well as equity items that are not expressed in terms of the current purchasing power at the balance sheet date, have been adjusted using the relevant correction coefficients.
  • d) All income statement accounts, excluding income statement accounts that are counterparty to nonmonetary accounts of balance sheet, are restated based on the price correlations of the date they were initially reflected in the financial statements.

Dividend Distribution

It was decided to distribute dividends amounting to nominal TL 5.540.433.882 (TL 4.861.655.783 based on the purchasing power on the date distribution decision was made) from the profits of 2024 as a result of the Ordinary General Assembly held as of March 28, 2025.

Going Concern

The interim condensed consolidated financial statements have been prepared on a going concern basis, assuming that the Group will benefit from its assets and fulfill its liabilities in the next year and in the natural course of its activities.

2.1 Basis of Presentation (cont'd)

Subsidiaries

Effective partnership interests and voting rights are disclosed in Note 1.

The interim condensed consolidated financial statements include the financial statements of businesses controlled by the Company and its subsidiaries. Control is ensured by the Company meeting the following conditions:

  • has power over the investee company/asset,
  • is exposed to or has the right to variable returns from the investee company/asset, and
  • ability to use its power in a way that can have an impact on returns.

If a situation or event occurs that may cause a change in at least one of the criteria listed above, the Company reevaluates whether it has control over its investment.

In cases where the Company does not have a majority voting right over the invested company/asset, it has control over the invested company/asset, provided that it has sufficient voting rights to direct/manage the activities of the relevant investment on its own.

The Company takes into account all relevant events and conditions in assessing whether a majority vote in the relevant investment is sufficient to provide control power, including the following factors:

  • Comparing the voting rights held by the Company with the voting rights held by other shareholders;
  • Potential voting rights held by the Company and other shareholders;
  • Rights arising from other contractual agreements and
  • Other events and conditions that may indicate whether the company has the current power to manage the relevant activities in situations where decisions need to be made (including votes made at general assembly meetings in previous periods).

Including a subsidiary within the scope of consolidation begins when the Company has control over the subsidiary and ends when it loses control. Income and expenses of subsidiaries acquired or disposed of during the year are included in the consolidated statement of profit or loss and other comprehensive income from the date of acquisition until the date of disposal.

Each item of profit or loss and other comprehensive income belongs to the shareholders of the parent company and non-controlling interests. The total comprehensive income of the subsidiaries is transferred to the parent company shareholders and the non-controlling interests, even if the non-controlling interests result in a reverse balance. If necessary, adjustments have been made to the accounting policies in the financial statements of subsidiaries to ensure that they are the same as the accounting policies followed by the Group. All in-group assets and liabilities, equity, income and expenses and cash flows relating to transactions between Group companies are eliminated on consolidation.

Changes in the capital share of the Group's existing subsidiary

Changes in the Group's capital interest in its subsidiaries that do not result in a loss of control are accounted for as equity transactions. The book values of the Group's share and non-controlling interests are adjusted to reflect changes in subsidiary shares. The difference between the amount by which non-controlling interests are adjusted and the fair value of the consideration received or paid is directly recognized as the Group's share in equity.

In case the Group loses control over a subsidiary, profit/loss after sale is calculated as the difference between (the sum of the sales price received and the fair values of the remaining share) and the previous book values of the assets (including goodwill) and liabilities of the subsidiary and the non-controlling interests. Amounts previously recognized and collected in equity regarding the subsidiary within other comprehensive income are recorded according to the accounting method to be used on the assumption that the Company has sold the relevant assets (for example, in accordance with the relevant TFRS standards, transferring them to profit/loss or transferring them directly to retained earnings).

2.2 Accounting Policies and Changes and Misstatements in Accounting Estimates

Significant changes in accounting policies are applied retrospectively and previous period financial statements are restated. The Group has not made any changes in its accounting policies during the current year.

If changes in accounting estimates are related to only one period, they are applied prospectively in the current period in which the change is made; if they are related to future periods, they are applied prospectively both in the period in which the change is made and in future periods. There has been no significant change in the Group's accounting estimates during the current year.

Identified material accounting errors are corrected retrospectively and previous period financial statements are rearranged. There is no material error detected by the Group in the current year.

2.3 Adoption of New and Revised Turkish Financial Reporting Standards

The accounting policies adopted in preparation of the interim condensed consolidated financial statements as of September 30, 2025 are consistent with those of the previous financial year, except for the adoption of new and amended TFRS and TFRS interpretations effective as of January 1, 2025 summarized below.

2.5 Comparative Information and Restatement of Prior Period Consolidated Financial Statements

The current period interim condensed consolidated financial statements of the Group include comparative financial information to enable the determination of the trends in financial position and performance.

Long-term provisions for employee benefits (cont'd)

The amount payable consists of one month's salary limited to a maximum of TL 53.919,68 for each period of service on September 30, 2025 (December 31, 2024: TL 41.828,42).

Severance pay liability is not subject to any kind of funding legally. Provision for retirement pay liability is calculated by estimating the present value of probable liability amount arising due to retirement of employees. TAS 19 Employee Benefits stipulates the development of company's liabilities by using actuarial valuation methods under defined benefit plans. In this direction, actuarial assumptions used in calculation of total liabilities are described as follows.

The principal assumption is that the maximum liability for each year of service will increase parallel with inflation. Thus, the discount rate applied represents the expected real rate after adjusting for the anticipated effects of future inflation. Consequently, in the accompanying consolidated financial statements as of September 30, 2025, the provision has been calculated by estimating the present value of the future probable obligation of the Company arising from the retirement of the employees.

Provisions in the relevant balance sheet dates have been calculated using the rates in the table below.

September 30, 2025
Discount rate 30,27% (fix)
Inflation rate 27,44% (fix)
The company's budgeted rate for July 1, 2025;
Salary increase is 1,5% above inflation thereafter
17,27% for July 1, 2025;
Severance pay ceiling increase in line with inflation thereafter
December 31, 2024
Discount rate 26,67% (fix)
Inflation rate 23,49% (fix)
The company's budgeted rate for January 1, 2025,
Salary increase is 1,5% above inflation thereafter
33,07% for January 1, 2025;
Severance pay ceiling increase in line with inflation thereafter

Estimated amount of retirement pay not paid due to voluntary leaves is also taken into consideration as 1% - 11% for employees with 0-15 years of service, and 0% for those with 15 or more years of service. Ceiling amount of TL 53.919,68 which is in effect since July 1, 2025 is used in the calculation of Groups' provision for retirement pay liability (July 1, 2024: TL 41.828,42) (the severance pay ceilings are expressed as the purchasing power of the specified dates).

Important estimates used in the calculation of employment termination benefits are discount rate, inflation rate and turnover probability.

Corporate Tax

The Group is subject to Turkish corporate taxes in force. The necessary provisions are allocated in the consolidated financial statements for the estimated liabilities based on the Group's results for the year. Turkish tax legislation does not permit a parent company and its subsidiary to file a consolidated tax return. Therefore, provisions for taxes, as reflected in the consolidated financial statements, have been calculated on a separate-entity basis.

Corporate tax is applied on taxable corporate income, which is calculated from the statutory accounting profit by adding back non-deductible expenses, and by deducting dividends received from resident companies, other exempt income and other incentives (prior year's losses if any and investment incentives used if preferred) utilized.

19. TAX ASSETS AND LIABILITIES (INCLUDING DEFERRED TAX ASSETS AND LIABILITIES) (cont'd)

Corporate Tax (cont'd)

Institutions with the Law No. 7456 published in the Official Gazette dated July 15, 2023 by making changes in the first paragraph of Article 32 of the Tax Law, the year 2023 and the following the corporate tax rate for corporate earnings of taxation periods has been increased to 25%. As of reporting date, the current corporate tax rate for the corporate earnings has been determined as 25% (December 31, 2024: 25%). Deferred tax rate is 12,5% (December 31, 2024: 12,5%) for valuation increases/decreases of financial investments ("listed on the stock exchange") held for more than two years. According to the laws of Romania and the Cyprus, it is calculated as 16% and 23,5% respectively, on the taxable corporate income after deducting the legally deductible expenses.

With the Law No. 7456 published in the 32249 numbered Official Gazette dated July 15,2023, the exemption rate to be applied to the gains arising from the sale of immovables which in companies' assests before July 15, 2023 has been determined as 25%, and the deferred tax rate to be applied based on the temporary differences arising on the revaluation of the related assets are 18,75%.

Deferred Tax

The Group recognizes deferred tax assets and liabilities based upon temporary differences arising between its financial statements in accordance with the TFRS and its statutory tax financial statements. These differences usually result in the recognition of income and expenses in different reporting periods for the TFRS regulations and tax purposes and are set out below.

Deferred tax assets and liabilities (excluding land) tax rate used for calculating corporate tax for the subsidiaries in Turkey in accordance with the additional provisional Article 10 of Corporate Tax Law; corporate tax rate is 25% for the corporate earnings to be obtained in the taxation periods of 2024 and following years.

Tax Advantages Obtained Under the Investment Incentives

Earnings of the Group that are derived from investments linked to an investment incentive certificate are subject to corporate tax at discounted rates for a certain period, which starts when the investment starts to partly or fully operate, and ends when the maximum investment contribution amount is reached. Within this scope, the Group has accounted for TL 363.027.216 (December 31, 2024: TL 353.626.604) of tax advantages as deferred tax assets which are expected to be recovered in the foreseeable future in the consolidated financial statements as of September 30, 2025. The contrubition amount between January 1 – September 30, 2025 benefited from the gain from investment is TL 698.315.786.

Deferred tax assets are recognized for deductible temporary differences, carry forward tax losses and indefinite-life investment incentives which allows payment of corporate tax at discounted rates, as long as it is probable that sufficient taxable income will be generated in the future. In this context, the Group recognizes deferred tax assets from investment incentives based on long-term plans, including taxable profit projections derived from business models, which are re-evaluated at each balance sheet date to assess recoverability of such deferred tax assets. The Group expects to recover such deferred tax assets within 5 years from the balance sheet date.

In the sensitivity analysis performed as of September 30, 2025, when the inputs of the key macroeconomic and sectoral assumptions that form the business plans are increased/decreased by 10%, there is no change in the projected 5-year recovery periods of deferred tax assets related to investment incentives.

27. THE NATURE AND LEVEL OF RISKS ARISING FROM FINANCIAL INSTRUMENTS

a) Capital risk management

The Group manages its capital to ensure that it will be able to continue as going concern while maximizing the return to stakeholders through the optimization of the debt and equity balance.

The capital structure of the Group consists of payables, which include the loans disclosed in Note 18, and equity items which comprise cash and cash equivalents, issued capital, reserves and prior years' profits, respectively.

The Group's key management reviews the cost of capital and risks related to each capital level. Based on recommendations of key management, the Group balances its overall capital structure through the payment of dividends, as well as the issue of new debt or the redemption of existing debt.

The Group management examines the capital by leverage ratio in order to be consistent with other companies in the industry. This ratio is calculated by dividing net debt by total capital. Net debt is obtained by subtracting cash and cash equivalents and short-term financial investments from total loans (including current and non-current loans as shown in the balance sheet). Total capital is calculated by adding "equity" item in the consolidated balance sheet and net debt.

Net Debt/Total Capital Ratio

Financial payables (Note 16) 3.964.589.752 279.008.552
Less: Cash and Cash Equivalents (Note 4) (13.925.574.069) (7.967.703.716)

Net Debt (12.033.118.187) (10.292.612.981)
Total Equity 59.016.862.781 57.222.982.817
Total Capital 4.861.655.783 4.861.655.783
Net Debt/Total Capital Ratio (2,48) (2,12)

b) Financial Risk Factors

The Group's activities expose it to market risk (currency risk, price risk), credit risk and liquidity risk. Group's risk management program generally focuses on uncertainty in financial markets and minimizing potential negative effects on Group's financial performance.

The main financial instruments used by the Group are bank loans, bonds issued, cash and short-term bank deposits. The main purpose of using these tools is to create financing for the Group's operations. The Company also has financial instruments, such as financial investments, trade receivables and trade payables, which arise directly from operations.

b.1) Market risk management

The operations of the Group are primarily exposed to financial risks related to changes in the exchange rate and interest rate.

Market risks are also evaluated with sensitivity analyses.

There has been no change in the Group's exposure to market risks or the management and measurement of exposures.

b.1.1) Foreign currency risk management

Transactions in foreign currency cause exchange rate risk. The Group is mainly exposed to foreign currency risk in Euro, US Dollar and Romanian Leu.

Sensitivity to exchange rate risk

The Group is mainly exposed to foreign currency risks in USD, Euro and Romanian Leu.

The following table shows the Group's sensitivity to a 20% (December 31, 2024: 20%) increase and decrease in USD, Euro and Romanian Leu. 20% (December 31, 2024: 20%) is the sensitivity rate used when reporting foreign currency risk internally to key management personnel and represents management's assessment of the possible change in foreign exchange rates. The sensitivity analysis only includes outstanding foreign currency denominated monetary items and adjusts their translation at the period end for a 20% (December 31, 2024: 20%) change in foreign currency rates. A positive number indicates an increase in profit / loss and other equity.
