All non-financial data presented in this press release is unconsolidated and comprises Turkcell Turkey only figures, unless otherwise stated. The terms “we”, “us”, and “our” in this press release refer only to Turkcell Turkey, except in discussions of financial data, where such terms refer to the Group, and except where context otherwise requires.

“Turkcell International” which comprises all of our telecom and digital services related businesses outside of Turkey.

In this press release, a year-on-year comparison of our key indicators is provided and figures in parentheses following the operational and financial results for June 30, 2023 refer to the same item as at June 30, 2022. For further details, please refer to our consolidated financial statements and notes as at and for June 30, 2023, which can be accessed via our website in the investor relations section (www.turkcell.com.tr).

Selected financial information presented in this press release for the second quarter and half year of 2022 and 2023 is based on Turkish Accounting Standards (TAS) / Turkish Financial Reporting Standards (TFRS) figures in TRY terms unless otherwise stated.

In the tables used in this press release totals may not foot due to rounding differences. The same applies to the calculations in the text.

Year-on-year and quarter-on-quarter percentage comparisons appearing in this press release reflect mathematical calculation.

NOTICE

We are publishing financial statements as of June 30, 2023 prepared in accordance with Turkish Accounting Standards/Turkish Financial Reporting Standards (“TAS”/”TFRS”) only. These standards are issued by the Public Oversight Accounting and Auditing Standards Authority (“POA”) and are in full compliance with IAS/IFRS Standards. In an announcement published by the POA on January 20, 2022, it is stated that TAS 29 “Financial Reporting in Hyperinflationary Economies” does not apply to TFRS financial statements as of December 31, 2021. Since then and as of the preparation date of our latest consolidated financial statements, no new statement has been made by the POA about TAS 29 application. Consequently, no TAS 29 adjustment was made to our consolidated financial statements.

Financial statements prepared in accordance with IFRS should apply IAS 29 “Financial Reporting in Hyperinflationary Economies” as of June 30, 2023. In this context, financial statements prepared in accordance with IFRS and TFRS would have significant differences and would not be comparable as of June 30, 2023. We intend to publish IFRS financial statements, compliant with IAS 29 to the extent that it remains applicable, with our Annual Report on Form 20-F that will be filed to the U.S. Securities and Exchange Commission.

Although we have not prepared a detailed comparison of differences between IFRS (unadjusted according to IAS 29) and TFRS, we have noted in our past financial statements that the most significant differences have appeared in the lines Other Operating Income/Expense, Finance Income/Expense, and Investment Activity Income/Expense. In the past, revenue, net income and EBITDA have generally not differed. While no assurance can be given that this will be the case for Q2 2023, we are not at present aware of changes that would cause other significant differences, other than those resulting from the application of IAS 29.

COMMENTS BY CEO, MURAT ERKAN

We are pleased to report another set of outstanding results despite a challenging quarter occupied by a hefty schedule. The domestic agenda during the second quarter was predominantly focused on elections, however, we observed a dynamic period as the major uncertainties faded through the end of the quarter and as we gradually entered into the summer months. For this quarter, in addition to the base effect of accelerated inflation in the same period of last year, inflation decelerated with the contribution of a tighter monetary policy and economic measures. These factors together gave rise to a positive outlook for the economy overall. The revival of economic activity in the second quarter of the year positively impacted our operations, which were further enhanced by increased mobility during the summer months. The steady actions which we had taken since the end of 2021 within the scope of our inflationary pricing policy, has made a significant contribution to preserving and strengthening our company’s financial performance. In April, considering prevailing market conditions and ongoing inflation, although it was decelerating, we continued our price adjustments that had been temporarily paused in the first quarter due to the earthquakes. In addition to a substantial rise in the minimum wage as of June, July’s inflation print signaled that despite the recent deceleration trend, another phase of accelerated inflation was upon us. Yet we continued to implement price adjustments in August remaining committed to our pricing strategy.

Our performance in the quarter improved due to the expansion of our subscriber base, the cumulative impact of sequential price increases, our focus on upsell to higher packages for our customers, and the contribution of our digital services and techfin business. Group revenues grew by 73.5% year-on-year to TRY 21.7 billion. EBITDA¹ increased by 89.3% to TRY 9.5 billion, yielding an EBITDA margin of 44.0%, driven by solid topline performance and energy price discounts. In addition to the strong operational performance, and despite currency volatility in the second quarter, our dynamic and prudent risk management contributed to a 70.1% year-on-year rise in net income to TRY 3.2 billion.

Strong results with sequential price adjustments

In the second quarter of the year we continued to focus on postpaid subscribers, gaining 165 thousand net mobile subscribers, of which 404 thousand were postpaid. During this period, overall price levels continued to rise as our price adjustments were followed by other operators. Yet the competitive effects of promotional sales being limited to short periods in response to aggressive attacks from the competition were also observed. Accordingly, following a subdued first quarter due to the earthquake, the Mobile Number Portability (MNP) market volume has increased to some extent. On the other hand, alternative data services particularly for tourists, and rising price levels suppressed tourists’ new line acquisitions, especially on the price-sensitive prepaid side. Mobile ARPU² rose 84.5% thanks to the accelerating impact of price adjustments, the expansion of the postpaid subscriber base to 70% and our ability to successfully upsell our customers to higher tariffs.

In the fixed broadband segment where we meet our customers’ demand for uninterrupted and fast connectivity; our contract-free packages also continued to attract attention in addition to our high-speed internet offerings of 100 Mbps and above. We followed the incumbent operator’s price increases in July and made price adjustments for our fixed customers in August. The more than half of our fiber subscribers have opted for the 12-month contracts or contract-free tariffs as of the end of this quarter, thanks to our strategic focus on those offerings, where we can reflect price adjustments to our subscribers in a timelier manner during the inflationary period. We reached a fixed broadband customer base of 3.0 million with a net addition of 40 thousand fiber subscribers. In addition to price adjustments, thanks to our focus on higher speed packages, especially among new subscribers, Residential Fiber ARPU gave a robust performance marking a year-on-year rise of 48.6%. This strong performance also exceeded the average inflation rate for the second quarter of the year. Lastly, by making 165 thousand new homepasses, in the first half of the year alone we exceeded our target of 300 thousand by the end of 2023.

We are enhancing the value that we provide to our customers through digital services and achieving strong results

In addition to our strong financial and operational growth, we are sustaining the success of our strategic focus areas. The stand-alone revenues of our digital services, including prominent brands such as BiP, TV+, lifebox, fizy, İşte Suit, GAME+, and digital advertising increased by 87% year-on-year to TRY 928 million in this quarter, while the number of stand-alone paid users³ in our digital services increased by 22% year-on-year to 5.5 million. Our communication platform, BiP, surpassed 1 million active users in Pakistan, further expanding its user base through international operator collaborations. Our cloud storage product lifebox, distinguished by its secure and intelligent technologies, achieved a significant milestone by surpassing 2 million paid users. Meanwhile, TV+, enriched with content from various domestic and international platforms, as well as leading global studios, is progressing towards becoming a comprehensive content platform. With its user-friendly interface, TV+ aims to provide subscribers all their content through a single box. We are enhancing our comprehensive collaborations with platforms such as SSport, BluTv, and Exxen, as well as strengthening partnerships with studios and platforms like Netflix, HBO, Paramount, and AMC. With the renewed ‘TV+ PRO,’ we have started providing service to all of our customers regardless of the infrastructure they use. During this quarter, our OTT TV subscribers exceeded 1 million, and with a net addition of 35 thousand IPTV subscribers, whereby we reached a total of 1.3 million IPTV subscribers. Meanwhile, the revenues of digital business services increased by 82% year-on-year to TRY 2.1 billion in this quarter. Our data center and cloud business maintained its robust growth trajectory this quarter as well. On the other hand, we currently have a backlog of TRY 2.9 billion from system integration and managed services projects.

Our techfin-focused services, the Financell⁴ and Paycell businesses continue to support the group’s growth. Financell offers customers a broad range of financial solutions by providing services in diverse areas such as device, car, and supplier financing to enhance product diversity. Loan portfolio of Financell reached TRY 4.7 billion during the quarter, supported by a strong rise in new loans issued to customers. This performance was also supported by the increase in average interest rates. Financell’s revenues grew by 87.4% year-on-year to TRY 402 million. The revenues of Paycell, Türkiye’s digital financial services platform, rose 95.2% year-on-year to TRY 388 million. We have doubled the volume of ‘Pay Later’, which is Paycell’s main revenue driver, reaching a volume of TRY 1.9 billion. In addition, with the nationwide joint QR project, we provide services at all stores where QR is available.

We raised our guidance on the back of accelerating growth thanks to our customer-focused strategies

We are upward-revising our guidance⁵ for the year 2023, supported by our strong half-year performance and confidence for the remainder of the year. Accordingly, we anticipate consolidated revenue growth of around 71% and EBITDA of approximately TRY 37.0 billion. We expect the ratio⁶ of operational capital expenditures to sales in the approximate range of 22%, in line with our previous expectations.

While expressing gratitude to all our employees who contributed to this success, we are also thankful to our Board of Directors for their trust and support. The continuous presence by our side of our customers and business partners empowers us, and we extend a special gratitude to them all.

Revenue of the Group grew by 73.5% year-on-year in Q223. Turkcell Turkey played a significant role in this performance, with solid ARPU growth resulting from price adjustments and successful upsell efforts as well as an expanding postpaid customer base. Our digital services and techfin business also contributed to overall revenue growth.

Turkcell Turkey revenues, comprising 79% of Group revenues, rose 82.3% year-on-year to TRY17,091 million (TRY9,377 million).

Consumer segment revenues grew 90.2% year-on-year based on price adjustments, upsell efforts, and a larger subscriber base.

Corporate segment revenues rose 83.3% year-on-year supported by the strong contribution of digital business services, up 82.3% year-on-year.

Standalone digital services revenues across consumer and corporate segments grew 87.2% year-on-year.

Wholesale revenues grew 51.6% year-on-year to TRY1,126 million (TRY743 million), positively impacted by currency movements, customers’ data capacity upgrades, and increased traffic.

Turkcell International revenues, comprising 10% of Group revenues, rose 47.8% to TRY2,187 million (TRY1,480 million) positively impacted by currency movements.

Techfin segment revenues, comprising 4% of Group revenues, increased 92.6% year-on-year to TRY797 million (TRY414 million). Paycell revenues grew 95.2% and Financell’s revenue rose 87.4% year-on-year. Please refer to the Techfin section for details.

Other subsidiaries’ revenues, at 7% of Group revenues, which include mostly non-group call center and energy business revenues, and consumer electronics sales revenues, rose 30.6% year-on-year to TRY1,575 million (TR1,206 million). This was driven mainly by increased call center and digital channel revenues.

Cost of revenue (excluding depreciation and amortization) decreased to 47.5% (51.5%) as a percentage of revenues in Q223. The increase in personnel expenses (0.9pp), and other cost items (0.3pp) was offset by the decline in interconnection cost (2.2pp), cost of goods sold (1.5pp), and energy expenses (1.5pp) as a percentage of revenues.

Administrative Expenses decreased to 2.6% (2.8%) as a percentage of revenues in Q223.

Selling and Marketing Expenses increased to 4.9% (4.6%) as a percentage of revenues in Q223, due mainly to the increase in personnel expenses (0.3pp) as a percentage of revenues.

Net impairment losses on financial and contract assets increased to 1.0% (0.8%) as a percentage of revenues in Q223.

EBITDA¹ rose 89.3% year-on-year in Q223, leading to an EBITDA margin of 44.0% (40.3%).

Turkcell Turkey’s EBITDA increased 98.2% year-on-year to TRY7,816 million (TRY3,944 million) with an EBITDA margin of 45.7% (42.1%).

The EBITDA of other subsidiaries rose to TRY169 million (TRY121 million).

Depreciation and amortization expenses increased 20.5% year-on-year in Q223.

Net finance expense rose to TRY11,242 million (TRY3,377 million) in Q223. This was driven mainly by higher FX losses from borrowings and issued bonds. The FX losses were partially offset by the gain from derivatives.

See Appendix A for details of net foreign exchange gain and loss.

Net other operating income increased to TRY5,491 million (TRY1,863 million) in Q223 due mainly to higher FX gains arising from foreign currency cash.

See Appendix A for details of net foreign exchange gain and loss.

Net investment activity income was TRY2,872 million in Q223 due mainly to fair value differences of currency-protected time deposits and FX gains arising from financial investments.

Income tax expense: The current tax expense increased to TRY496 million (TRY76 million) due mainly to a higher deferred tax expense incurred in Q223.

Net income of the Group rose 70.1% to TRY3,161 million (TRY1,858 million) in Q223. This rise was driven mainly by a solid operational performance despite the higher net finance expense registered in Q223. The FX loss from borrowings and bonds was partially offset by the positive impact of derivative instruments and higher FX gains from foreign currency cash.

(1) EBITDA is a non-GAAP financial measure. See page 15 for the explanation of how we calculate adjusted EBITDA and its reconciliation to net income.

Total cash & debt: Consolidated cash as of June 30, 2023 increased to TRY35,030 million from TRY27,317 million as of March 31, 2023. Our cash position was positively impacted by the currency movements. Excluding FX swap transactions, 58% of our cash is in US$, and 10% in EUR.

Consolidated debt as of June 30, 2023 rose to TRY77,198 million from TRY58,486 million as of March 31, 2023, due mainly to the impact of currency movements and new borrowings. TRY3,936 million of our consolidated debt is comprised of lease obligations. Please note that 44% of our consolidated debt is in US$, 28% in EUR, 2% in CNY, 5% in UAH, and 20% in TRY.

Net debt¹ as of June 30, 2023, was at TRY28,046 million with a net debt to EBITDA ratio of 1.0 times. Excluding finance company customer loans, our telco only net debt was at TRY23,361 million with a leverage of 0.8 times.

Turkcell Group had a long FX position of US$84 million as at the end of the second quarter (Please note that this figure takes hedging portfolio and advance payments into account). The long FX position of US$84 million is in line with our FX neutral definition, which is between -US$200 million and +US$200 million.

Capital expenditures: Capital expenditures, including non-operational items, amounted to TRY8,229.1 million in Q223. In Q223 and H123, operational capital expenditures (excluding license fees) at the Group level were at 18.6% and 19.2% of total revenues, respectively.

(1) Starting from Q421, we have revised the definition of our net debt calculation to include “financial assets” reported under current and non-current assets. Required reserves held in CBRT balances are also considered in net debt calculation. We believe that these assets are highly liquid and can be easily converted to cash without significant change in value.

(3) Churn figures represent average monthly churn figures for the respective quarters.

Although there have been aggressive campaigns by competitors, our mobile subscriber base reached 37.6 million in the second quarter of 2023 supported by seasonality effect which is lower than normal trend. We registered 404 thousand quarterly net additions to the postpaid subscriber base, which reached 69.9% (67.0%) of total mobile subscribers. Meanwhile, our prepaid subscriber base decreased by 239 thousand mainly due to changing market dynamics. Alternative data solutions that provide services for tourists and rising new acquisitions price levels particularly suppressed the price-sensitive prepaid segment. Due to the negative effect of the earthquake, the MNP market was rationalized as other operators followed our price increases in Q123. The mobility in the market rose due to the aggressive campaigns by competitors in the second quarter of the year. We responded swiftly with our competitive offers to this change in market environment. Accordingly, our mobile ARPU (excluding M2M) exceeded the highest average inflation of last year and rising by 84.5% year-on-year on the back of price adjustments, larger postpaid subscriber base, and upsell performance in Q223. The average monthly mobile churn rate slightly increased to 1.9% in Q223 which is still a healthy level.

Average monthly mobile data usage per user increased by 17% year-on-year to 16.5 GB in Q223. The average mobile data usage of 4.5G users was 17.6 GB in Q223.

Total smartphone penetration on our network reached 89% in Q223 on a 2.2pp year-on-year increase. 94% of those smartphones are 4.5G compatible smartphones.

On the fixed front, our fiber subscriber base continued to grow in Q223, with 40 thousand net additions driven by demand for high-speed and quality broadband connection. Total fixed subscribers reached 3.0 million on 33 thousand quarterly net additions in Q223. Meanwhile, IPTV subscribers exceeded 1.3 million on 35 thousand quarterly net additions. Our residential fiber ARPU growth was 48.6% year-on-year in Q223, driven mainly by price adjustments and increased IPTV penetration at 67% as well as upsell efforts to higher tariffs. The average monthly fixed churn rate stood at 1.4%.

(1) Since July 10, 2015, we hold a 100% stake in lifecell.

lifecell (Ukraine) revenues increased by 36.5% year-on-year in local currency terms, driven mainly by the increase in ARPU which has been supported by price adjustments and higher data consumption. lifecell registered an EBITDA margin of 59.1% on a 1.2pp improvement year-on-year mainly driven by a decrease in interconnection and energy expenses as a percentage of revenues. Meanwhile, solid operational performance allowed lifecell to register a positive net income in Q223.

lifecell revenues in TRY terms rose 45.1% year-on-year in Q223, mainly with the positive impact of currency movements. lifecell’s EBITDA in TRY terms grew 48.2%, leading to an EBITDA margin of 59.1%.

(3) Active subscribers are those who in the past three months made a revenue generating activity.

lifecell’s three-month active subscribers remained stable at 8.6 million in Q223. The 3-month active ARPU growth increased by 36.1% year-on-year and by 7.7% on a quarter-on-quarter basis. Meanwhile, 3-month active 4.5G users rose 5.5% year-on-year in Q223. lifecell’s smartphone penetration was at 84.6% as at the end of Q223.

(1) BeST, in which we hold an 100% stake, has operated in Belarus since July 2008.

BeST revenues grew by 22.4% year-on-year in local currency terms in Q223 due mainly to an increase in data traffic, and 15% ARPU increase driven by upsells and price adjustments as well as a 9.1% increase in three-month active subscriber base.

Net income	66.1	123.2	86.4%	115.2	202.0	75.3%

In Q223, Paycell experienced a significant 95.2% rise in revenue compared to the previous year, primarily driven by the continuous high demand for digital payment services. Paycell’s varied product portfolio, encompassing mobile payment services, POS solutions, and the Paycell card, particularly the Pay Later solution, was strategically utilized to address and meet the growing demand. Paycell’s EBITDA rose 110.3% year-on-year, leading to an EBITDA margin of 48.3% on 3.5pp improvement in Q223 thanks to an increase in the profitability of payment solutions.

The Pay Later service transaction volume more than doubled year-on-year to TRY1.9 billion. This was driven by a 23% increase in the 3-month active users of the Pay Later service to 5.5 million and their increased usage. Meanwhile, the Paycell Card transaction volume almost doubled year-on-year to TRY3.4 billion in Q223. Additionally, in Q223 the transaction volume of POS solutions reached TRY4.7 billion. Moreover, the QR project has been completed, and payments can now be made with Paycell at all places where QR code payments are accepted. Overall, Paycell’s total transaction volume across all services increased to TRY15 billion, driven mainly by 13% year-on-year rise in Paycell’s total 3-month active users to 7.9 million and their increased usage in Q223.

Net income	79.2	157.7	99.1%	146.4	266.6	82.1%

Financell experienced a significant revenue boost during Q223, with an 87.4% year-on-year increase. This growth was fueled primarily by the expansion of their loan portfolio and the higher average interest rate on the loans compared to the same period of last year. Financell also reported 45.3% year-on-year growth in EBITDA. However, the EBITDA margin saw a decline compared to the previous year due to higher funding costs in Q223. In addition to solid revenue and EBITDA growth, Financell’s net income registered 99.1% growth year-on-year.

The loan portfolio of Financell demonstrated significant growth, increasing from TRY2.5 billion in Q222 to TRY4.7 billion in Q223. This expansion can be attributed to increased mobility and higher lending to the corporate segment. Financell’s cost of risk decreased from 2.7% in Q123 to 1.9% in Q223 due mainly to the decline in the negative effects of the February earthquakes. Additionally, Financell has extended loans to over 25 thousand corporate customers.

(1) Following the change in the organizational structure, the revenues of Turkcell Sigorta Aracılık Hizmetleri A.Ş. (Insurance Agency), which was previously managed under the Financell, has been classified from Financell to “Other” in the Techfin segment as of the first quarter of 2023. Within this scope, all past data have been revised for comparability purposes.

RECONCILIATION OF NON-GAAP FINANCIAL MEASUREMENTS: We believe Adjusted EBITDA, among other measures, facilitates performance comparisons from period to period and management decision making. It also facilitates performance comparisons from company to company. Adjusted EBITDA as a performance measure eliminates potential differences caused by variations in capital structures (affecting interest expense), tax positions (such as the impact of changes in effective tax rates on periods or companies) and the age and book depreciation of tangible assets (affecting relative depreciation expense). We also present Adjusted EBITDA because we believe it is frequently used by securities analysts, investors and other interested parties in evaluating the performance of other mobile operators in the telecommunications industry in Europe, many of which present Adjusted EBITDA when reporting their results.

Our Adjusted EBITDA definition includes Revenue, Cost of Revenue excluding depreciation and amortization, Selling and Marketing expenses, Administrative expenses and Net impairment losses on financial and contract assets, but excludes finance income and expense, other operating income and expense, investment activity income and expense, share of profit of equity accounted investees and minority interest.

Nevertheless, Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation from, or as a substitute for analysis of our results of operations, as reported under TFRS. The following table provides a reconciliation of Adjusted EBITDA, as calculated using financial data prepared in accordance with TFRS to net profit, which we believe is the most directly comparable financial measure calculated and presented in accordance with TFRS.

CONDENSED CONSOLIDATED FINANCIAL STATEMENT OF CASH FLOWS FOR THE SIX MONTH INTERIM PERIOD ENDED 30 JUNE 2023

(All amounts are expressed in thousand of Turkish Lira unless otherwise stated. Currencies other than Turkish Lira are expressed in thousands unless otherwise stated.)

BASIS OF PRESANTATION OF FINANCIAL STATEMENTS

2.1 Basis of Presentation

The Group prepared its interim condensed financial statements as of and for the six month interim period ended 30 June 2023 in accordance with Turkish Accounting Standards No:34 Interim Financial Reporting.The Group’s interim condensed consolidated financial statement does not include all disclosures and notes that should be included at year-end financial statements. Therefore, the interim condensed consolidated financial statements should be examined together with the 31 December 2022 year-end financial statements.

The accompanying condensed interim consolidated financial statements are prepared in accordance with Communiqué Serial II, No: 14,1, “Principles of Financial Reporting in Capital Markets” (“the Communiqué”) published in the Official Gazette numbered 28676 on 13 September 2013. According to Article 5 of the Communiqué, interim condensed consolidated financial statements are prepared in accordance with Turkish Financial Reporting Standards (“TFRS”) issued by Public Oversight Accounting and Auditing Standards Authority (“POA”), its addendum and interpretations. The Group’s interim condensed consolidated financial statements are presented in accordance with announcement regarding “Formats of Financial Statements and its Notes” by POA on 20 May 2013. The Group has made required adjustments and classifications in accordance with “the illustrative Financial Statements and User Guide” and “2022 TFRS Taxonomy” published by POA on 10 October 2022.

Restatement of Financial Statements During the Hyperinflationary Periods

POA made an announcement on 20 January 2022 whether entities applying TFRS will apply TAS 29 Financial Reporting in Hyperinflationary Economies (“TAS 29”) in the 2021 financial reporting period. According to this announcement, it is stated that entities applying TFRS do not need to make any adjustments within the scope of TAS 29 in their financial statements for year ended 2021. As of the reporting date, there is no updated announcement has been made by the POA regarding the scope and application of TAS 29. In this context, no inflation adjustment was made according to TAS 29 in the condensed consolidated financial statements as of 30 June 2023.

2.2

Changes in Accounting Policies and Errors

Significant changes in accounting policies and significant accounting errors detected are applied retrospectively and the prior period financial statements are restated. In order to comply with the presentation of the current period consolidated financial statements, comparative information is reclassified when deemed necessary and important differences are disclosed. There has been no significant change in the Group’s accounting policies in the current period.

2.3

New standards and interpretations

The accounting policies adopted in preparation of the consolidated financial statements as of 30 June 2023 are consistent with those of the previous financial year, except for the adoption of new and amended TFRS and TFRS interpretations effective as of 1 January 2023 and thereafter. The effects of these standards and interpretations on the Group’s financial position and performance have been disclosed in the related paragraphs.

i) The new standards, amendments and interpretations which are effective as of 1 January 2023 are as follows:

Amendments to TAS 8 - Definition of Accounting Estimates

In August 2021, POA published amendments to TAS 8 that introduce a new definition for “accounting estimates”. The amendments clarify the distinction between changes in accounting estimates and changes in accounting policies and correction of errors.

BASIS OF PRESENTATION OF FINANCIAL STATEMENTS (cont’d)

2.3

New standards and interpretations (cont’d)

Amendments to TAS 8 - Definition of Accounting Estimates (cont’d)

In addition, the amended standard clarifies that the effects of a change in input or a change in a measurement technique on the accounting estimate are changes in accounting estimates unless they result from a correction for prior period errors. The previous definition of change in accounting estimate stated that changes in accounting estimates could result from new information or new developments. Therefore, such changes are not considered as corrections of errors. This aspect of the definition has been preserved by the POA. The amendments did not have a significant impact on the financial position or performance of the Group.

Amendments to TAS 1 - Disclosure of Accounting Policies

In August 2021, POA issued amendments to TAS 1, in which it provides guidance and examples to help entities apply materiality judgements to accounting policy disclosures. In the absence of a definition of the term ‘significant’ in TFRS, the POA decided to replace it with ‘material’ in the context of disclosing accounting policy information. ‘Material’ is a defined term in TFRS and is widely understood by the users of financial statements, according to the POA. In assessing the materiality of accounting policy information, entities need to consider both the size of the transactions, other events or conditions and the nature of them. Examples of circumstances in which an entity is likely to consider accounting policy information to be material have been added. The amendments did not have a significant impact on the financial position or performance of the Group.

Amendments to TAS 12 – Deferred Tax related to Assets and Liabilities arising from a Single Transaction

In August 2021, POA issued amendments to TAS 12, which narrow the scope of the initial recognition exception under TAS 12, so that it no longer applies to transactions that give rise to equal taxable and deductible temporary differences. The amendments clarify that where payments that settle a liability are deductible for tax purposes, it is a matter of judgement (having considered the applicable tax law) whether such deductions are attributable for tax purposes to the liability recognised in the financial statements (and interest expense) or to the related asset component (and interest expense). This judgement is important in determining whether any temporary differences exist on initial recognition of the asset and liability. The amendments apply to transactions that occur on or after the beginning of the earliest comparative period presented. In addition, at the beginning of the earliest comparative period presented, a deferred tax asset (provided that sufficient taxable profit is available) and a deferred tax liability for all deductible and taxable temporary differences associated with leases and decommissioning obligations should be recognized.

Standards, interpretations and amendments to existing standards that are issued but not yet effective up to the date of issuance of the consolidated financial statements are as follows. The Group will make the necessary changes if not indicated otherwise, which will be affecting the consolidated financial statements and disclosures, when the new standards and interpretations become effective. The amendments did not have a significant impact on the financial position or performance of the Group.

ii) Standards that are issued but not yet effective and early adopted

Amendments to TFRS 10 and TAS 28: Sale or Contribution of Assets between an Investor and its Associate or Joint Venture

In December 2017, POA postponed the effective date of this amendment indefinitely pending the outcome of its research project on the equity method of accounting. Early application of the amendments is still permitted. The Group will wait until the final amendment to assess the impacts of the changes. The Group will wait until the final amendment to assess the impacts of the changes.

New standards and interpretations (con’d)

TFRS 17 - The New Standard for insurance contracts

POA issued TFRS 17 in February 2019, a comprehensive new accounting standard for insurance contracts covering recognition and measurement, presentation and disclosure. TFRS 17 model combines a current balance sheet measurement of insurance contract liabilities with the recognition of profit over the period that services are provided. Certain changes in the estimates of future cash flows and the risk adjustment are also recognised over the period that services are provided. Entities will have an option to present the effect of changes in discount rates either in profit and loss or in OCI.

The standard includes specific guidance on measurement and presentation for insurance contracts with participation features. In accordance with amendments issued by POA in December 2021, entities have transition option for a “classification overlay” to avoid possible accounting mismatches between financial assets and insurance contract liabilities in the comparative information presented on initial application of TFRS 17. The mandatory effective date of the Standard for the following entities has been postponed to accounting periods beginning on or after January 1, 2024 with the announcement made by the POA:

Insurance, reinsurance and pension companies.

Banks that have ownership/investments in insurance, reinsurance and pension companies and

Other entities that have ownership/investments in insurance, reinsurance and pension companies.

The Group is in the process of assessing the impact of the amendments on financial position or performance of the Group.

Amendments to TAS 1- Classification of Liabilities as Current and Non-Current Liabilities

In January 2021 and January 2023, POA issued amendments to TAS 1 to specify the requirements for classifying liabilities as current or non-current. According to the amendments made in January 2023 if an entity’s right to defer settlement of a liability is subject to the entity complying with the required covenants at a date subsequent to the reporting period (“future covenants”), the entity has a right to defer settlement of the liability even if it does not comply with those covenants at the end of the reporting period. In addition, January 2023 amendments require an entity to provide disclosure when a liability arising from a loan agreement is classified as non-current and the entity’s right to defer settlement is contingent on compliance with future covenants within twelve months. This disclosure must include information about the covenants and the related liabilities. The amendments clarified that the classification of a liability is unaffected by the likelihood that the entity will exercise its right to defer settlement of the liability for at least twelve months after the reporting period. The amendments are effective for periods beginning on or after 1 January 2024. The amendments must be applied retrospectively in accordance with TAS 8. Early application is permitted. However, an entity that applies the 2021 amendments early is also required to apply the 2023 amendments, and vice versa. The Group is in the process of assessing the impact of the amendments on financial position or performance of the Group.

Amendments to TFRS 16 - Lease Liability in a Sale and Leaseback

In January 2023, POA issued amendments to TFRS 16. The amendments specify the requirements that a seller-lessee uses in measuring the lease liability arising in a sale and leaseback transaction, to ensure the seller-lessee does not recognise any amount of the gain or loss that relates to the right of use it retains. In applying requirements of TFRS 16 under “Subsequent measurement of the lease liability” heading after the commencement date in a sale and leaseback transaction, the seller lessee determines ‘lease payments’ or ‘revised lease payments’ in such a way that the seller-lessee would not recognise any amount of the gain or loss that relates to the right of use retained by the seller-lessee. The amendments do not prescribe specific measurement requirements for lease liabilities arising from a leaseback. The initial measurement of the lease liability arising from a leaseback may result in a seller-lessee determining ‘lease payments’ that are different from the general definition of lease payments in TFRS 16. The seller-lessee will need to develop and apply an accounting policy that results in information that is relevant and reliable in accordance with TAS 8. A seller-lessee applies the amendments to annual reporting periods beginning on or after 1 January 2024.

Amendments to TFRS 16 - Lease Liability in a Sale and Leaseback (cont’d)

Earlier application is permitted. A seller-lessee applies the amendments retrospectively in accordance with TAS 8 to sale and leaseback transactions entered into after the date of initial application of TFRS 16. The Group is in the process of assessing the impact of the amendments on financial position or performance of the Group.

iii) The new amendments that are issued by the International Accounting Standards Board (IASB) but not issued by Public Oversight Authority (POA)

The following amendments to IAS 12 as well as IAS 7 and IFRS 7 are issued by IASB but not yet adapted/issued by POA. Therefore, they do not constitute part of TFRS. the Group will make the necessary changes to its consolidated financial statements after the amendments are issued and become effective under TFRS.

Amendments to IAS 12 - International Tax Reform – Pillar Two Model Rules

In May 2023, IASB issued amendments to IAS 12, which introduce a mandatory exception in IAS 12 from recognizing and disclosing deferred tax assets and liabilities related to Pillar Two income taxes. The amendments clarify that IAS 12 applies to income taxes arising from tax laws enacted or substantively enacted to implement the Pillar Two Model Rules published by the Organization for Economic Cooperation and Development (OECD). The amendments also introduced targeted disclosure requirements for entities affected by the tax laws. The Group is in the process of assessing the impact of the amendments on financial position or performance of the Group.

Amendments to IAS 7 and IFRS 7 - Disclosures: Supplier Finance Arrangements

The amendments issued in May 2023 specify disclosure requirements to enhance the current requirements, which are intended to assist users of financial statements in understanding the effects of supplier finance arrangements on an entity’s liabilities, cash flows and exposure to liquidity risk. Supplier finance arrangements are characterized by one or more finance providers offering to pay amounts an entity owes its suppliers and the entity agreeing to pay according to the terms and conditions of the arrangements at the same date as, or a date later than, suppliers are paid. The amendments require an entity to provide information about terms and conditions of those arrangements, quantitative information on liabilities related to those arrangements as at the beginning and end of the reporting period and the type and effect of non-cash changes in the carrying amounts of those liabilities. In the context of quantitative liquidity risk disclosures required by IFRS 7, supplier finance arrangements are also included as an example of other factors that might be relevant to disclose. The Group is in the process of assessing the impact of the amendments on financial position or performance of the Group.

Other ongoing lawsuits and tax investigations

Probability of an outflow of resources embodying economic benefits for 2018 and 2019 fiscal years with regards to notification of Information and Communication Technologies Authority for radio fee related to 2018 fiscal year was considered by the Company management. In this respect, TL 128,429 was paid in November 2019 by reserving our right to take legal actions and legal actions were taken for 2018 fiscal year. The Court rejected the cases. The Company appealed the decisions before the Regional Administrative Court.

On the other hand, mobile payment services provided by Turkcell Ödeme were investigated within the scope of the Law No. 6493 and secondary legislation issued pursuant to this Law. As a result of the investigation, an administrative fine was imposed on Turkcell Ödeme in the amount of TL 18,763. Turkcell Ödeme filed a lawsuit for the cancellation of the aforementioned administrative fine. The hearing was held on 30 December 2020 in this case.

Within the scope of the Law No. 7440 on the Restructuring Some Receivables and Amending Some Laws, a restructuring application has been filed for the administrative fine which is the subject of the lawsuit. The administrative fine restructured by paying TL 1.443 on 31 July 2023. The court decided there is no need to make a decision regarding the essence of the case, due to waiving the case according to the Law No. 7440.

The Court accepted the case and cancelled the payment order. Tax office appealed the decision before the Regional Administrative Court. The Company replied this appeal request in due time.

DERIVATIVE INSTRUMENTS (cont’d)

Fair value of derivative instruments and risk management

Fair value:

Hierarchy on the presentation of financial assets and liabilities at their fair values:

The fair values of financial assets and financial liabilities are determined and grouped as Level 1, Level 2, Level 3:

Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the entity can access at the measurement date;

Level 2 inputs are inputs, other than quoted prices included within Level 1, that are observable for the asset or liability, either directly or indirectly; and

Level 3 inputs are unobservable inputs for determine fair value of asset or liability.

The table below provides information on fair value measurement of financial assets and liabilities:


	Fair value level	Valuation tecnique
a) Participating cross currency swap contracts	Level 3	Pricing models based on discounted cash flows calculated in-line with yield curves
b) Fx swap, currency, interest swap and option contracts	Level 2	Pricing models based on discounted cash flows calculated in-line with observable yield curves
c) Currency forward contracts	Level 2	Pricing models based on forward exchange rates at the reporting date

There were no transfers between fair value hierarchy levels during the year.

Since the bid-ask spread is unobservable input; in the valuation of participating cross currency swap contracts, prices in the bid- ask price range that were considered the most appropriate were used instead of mid prices. If mid prices were used in the valuation the fair value of participating cross currency swap contracts would have been TL 29,298 lower as of 30 June 2023 (31 December 2022: TL 15,892).

As of 30 June 2023, the Company has no financial assets and liabilities carried at fair value on a non-recurring basis.

The details of the movement between the opening and closing balances of derivative instruments with level 3 hierarchy are shown in the table below:

The reform and replacement of benchmark interest rates such as USD LIBOR and other interbank offered rates (‘IBORs’) has become a priority for global regulators. As of 30 June 2023, the Company completed the amendments to the contractual terms of the USD LIBOR-referenced floating-rate debt and updating hedge designations.

In USD LIBOR transition, designated hedging relationship remained the same due to no changes to payment plans and fixed interest rates of the USD LIBOR-referenced floating-rate debt in relation to derivative transactions. Thus, no modification applied regarding transactions.

Fair values:

Hierarchy of financial assets and liabilities that recognized at fair value:

Methods and assumptions used in fair value measurement of derivative instruments are explained in Note 16.

Fair value of cash and cash equivalents and debt securities issued are classified as Level 1 and fair value of other financial assets and liabilities are classified as Level 2.

Financial assets:

Carrying values of a significant portion of financial assets do not differ significantly from their fair values due to their short-term nature.

Financial liabilities:

As of 30 June 2023 and 31 December 2022; for the majority of the borrowings, the fair values are not materially different from their carrying amounts since the interest payable on those borrowings is either close to current market rates or the borrowings are of a short-term nature. The carrying amounts and fair values of non-current borrowings and current portion of non-current borrowings are as follows:

	30 June 2023				31 December 2022
	Carrying amount		Fair Value		Carrying amount		Fair Value
Bank loans		33,387,010		31,135,878		22,900,345		21,453,658

EXPLANATIONS ON SEASONALITY

The Turkish mobile communications market is affected by seasonal peaks and troughs. Historically, the effects of seasonality on mobile communications usage has positively influenced our results in the second and third quarters of the fiscal year and negatively influenced our results in the first and fourth quarters of the fiscal year. These seasonality effects have been less significant on mobile communication of the Company’s subscribers due to the changing market dynamics such as ICTA’s interventions in tariffs and increasing competition in the telecommunications sector.
