Please note that all financial data is consolidated and comprises that of Turkcell Iletisim Hizmetleri A.S. (the “Company”, or “Turkcell”) and its subsidiaries and associates (together referred to as the “Group”), unless otherwise stated.

We have four reporting segments:

"Turkcell Turkey" which comprises our telecom, digital services and digital business services related businesses in Turkey (as used in our previous releases in periods prior to Q115, this term covered only the mobile businesses). 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.

“Techfin” which comprises all of our financial services businesses.

“Other” which mainly comprises our non-group call center and energy businesses, retail channel operations, smart devices management and consumer electronics sales through digital channels and intersegment eliminations.

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 March 31, 2023 refer to the same item as at March 31, 2022. For further details, please refer to our consolidated financial statements and notes as at and for March 31, 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 first and fourth quarters of 2022 and the first quarter of 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 March 31, 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 March 31, 2023. In this context, financial statements prepared in accordance with IFRS and TFRS would have significant differences and would not be comparable as of March 31, 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 Q1 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.

EBITDA up 57.1% leading to an EBITDA margin of 39.1%; EBIT up 83.7% resulting in an EBIT margin of 23.6%

Net income up 250.8% to TRY2.8 billion

Net leverage³ level at 0.9x; net short FX position of US$31 million

	o	342 thousand quarterly mobile postpaid net additions; postpaid subscriber base share at 69.1%
	o	38 thousand fiber net additions
	o	160 thousand new fiber homepasses
	o	Mobile ARPU⁴ exceeded the average of inflation rate and rose by 67.9% year-on-year in Q123 mainly on the back of gradual price adjustments over the last year, upsell to higher tariffs and larger postpaid subscriber base
	o	Residential fiber ARPU growth of 31.4% year-on-year
	o	Average monthly data usage of 4.5G users at 17.4 GB in Q123; smartphone penetration at 88%

COMMENTS BY CEO, MURAT ERKAN

The wounds of the earthquake have begun to heal

The wounds of the February earthquake epicentered in Kahramanmaraş, one of the worst disasters in our history, have been swiftly addressed. While all resources are being mobilized for the reconstruction and recovery of the affected region, as Turkiye’s Turkcell we, too, are supporting the region with various employment and education-focused projects. As part of the “Turkcell Employment Mobilization” project we will, in the first stage, provide employment to 1,100 citizens and their families affected by the earthquake across 11 provinces. In addition, with our Call and Vocational Training Center to be established in Hatay, we aim to support earthquake victims not only with training, but also by providing areas for socialization. Meanwhile, with the technical and personal development programs of Turkcell Academy, we aim to provide the region with a qualified workforce of 5,000 people. As Turkcell, we will continue our efforts at full speed to improve the conditions of those affected by the earthquake and alleviate their suffering.

Mobile ARPU growth outpaced inflation

In the first quarter, despite the new subscriber demand in the earthquake-affected region and regulatory tourist line closures, we saw a net total add of 48 thousand subscribers. On the mobile side, we achieved a net add of 342 thousand postpaid subscribers in line with our focus on this segment. On the other hand, we lost 367 thousand prepaid subscribers due to regulatory closures we made this quarter among such subscribers acquired in high numbers from tourists and visitors in 2022. The mobile churn rate slightly increased on an annual basis to 1.7%.

Regarding market competition dynamics, it is fair to state that the first quarter of the year was more balanced compared to the same period of last year due to the earthquake impact. We saw the year-end aggressiveness continue in the early months of the year. Yet as the MNP market volume decreased during the earthquake period and aggressive campaigns subsided in march, the market became more rational.

We continued our infrastructure investments to provide our citizens with the internet speeds they deserve, and aware that the digitalization of our country depends on the fiber internet infrastructure. Within the framework of our goal of reaching 300 thousand new homepasses in 2023, we extended our end-to-end fiber service to 160 thousand new homepasses this quarter reaching a total of 5.5 million households. As a result of our strategic investments, we gained a net 38 thousand fiber customers in the first quarter of the year. The strong demand for our high-speed packages continued in this quarter. On the fiber side, the share among new customers of packages with speeds of over 100 Mbps increased by 22 percentage points compared to the same period of last year to 44%. Again, in this period, our customers also appreciated the no-commitment packages we offered for the first time in the fiber segment. On the other hand, due to the earthquake effect, fixed churn rate rose slightly on an annual basis. The fixed and fiber residential churn rates were 1.5% and 1.2%, respectively. Despite the earthquake impact, the subscribers of IPTV, which we especially offer to our fiber customers, increased by 28 thousand this quarter.

In line with our inflationary pricing policy, the sequential price adjustments since the end of 2021 and the slowdown in inflation led mobile ARPU growth to outpace inflation, as expected. Mobile ARPU¹, which continued its upward momentum, increased by 67.9% in the first quarter of the year, while the average inflation rate during the period was 54.3%. On the fixed side, the revenue reflection of price adjustments is more extended when compared to mobile due to a longer contract period. In addition, with the actions we have taken for customers in the earthquake region, Residential Fiber ARPU grew 31.4% on a year-on-year basis.

In the first quarter of 2023, our consolidated revenues increased by 61.5% year-on-year to TRY17.3 billion, while EBITDA² rose by 57.1% to TRY6.8 billion compared to the same period of last year. Our net profit rose by 250.8% to TRY2.8 billion, thanks to our strong operational performance, lower FX losses and an effective cash management.

Strong performance from our focus areas continued

The stand-alone paid users of our digital services and solutions, which is among our strategic focus areas, rose 24% year-on-year to 5.2 million, while their stand-alone revenues rose 65,2%. TV+, which enriches its offering with domestic and foreign content, continues to strengthen its market position in the through consistent improvement in service quality. In this regard, TV+'s net promoter score (NPS) has steadily increased over the past four quarters, and as of this quarter TV+ leads the market. TV+ has been steadily raising its share in the paid TV market since the second quarter of 2014, and according to the fourth quarter ICTA report, it has increased its market share to 16.5%. Despite the earthquake impact, IPTV subscribers have reached 1.3 million on a 16% year-on-year increase, while OTT TV subscribers maintained a similar yearly increase sustaining 1.0 million subscribers.

The revenues of digital business services that offer solutions for companies' digital transformation increased by 103.9% year-on-year, exceeding TRY1.6 billion in the first quarter of 2023. The revenue of our data center and cloud business services, which increase their share in digital business services revenue each quarter, more than doubled in revenue year-on-year. In this quarter, we signed 1,163 new projects with a total contract size of 1.8 billion TRY, of which TRY1.2 billion comprised system integration and managed services projects. Through this project portfolio, we have a backlog of TRY2.5 billion in contract value to be collected after the second quarter of 2023.

Our third focus area, techfin, where we provide services under the Financell and Paycell brands, continued to support group growth. Financell³’s revenue reached TRY317 million, up 64.6% year on year. This performance was driven by a credit portfolio reaching TRY3.9 billion and an increase in average interest rates. Paycell, Turkiye's digital payment platform, saw its revenues rise 79.4% year-on-year to TRY294 million. “Pay Later”, which accounts for 71% of Paycell revenue, doubled its transaction volume compared to the same period of last year, thanks to a rising number of users, being preferred in digital content such as transactions in Apple and Android markets.

The first deliveries of domestically produced smart device Togg T10X, for which pre-sales demand was exceed nine-fold of the production, began to be made in April. The T10X has the distinction of being the first vehicle in the world to be sold through an electronic wallet. During the presale period of T10X, which is the first vehicle to be sold via an electronic wallet, a volume of around TRY11 billion has been executed via Trumore wallet for which Paycell provided its infrastructure. Our Paycell virtual POS product, designed for corporate consumers, and enjoying high demand, will also mediate payments at "Trugo" charging stations.

I take this opportunity to thank our Board of Directors and all our team members for their support in making a strong start to the year, despite the challenges we faced and grief we suffered together this quarter. I also express our gratitude to our customers and business partners who remain with us on our journey towards success.

(3) 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.

Revenue of the Group rose 61.5% year-on-year in Q123. Turkcell Turkey played a significant role in this performance given its robust ARPU growth, which was positively impacted by price adjustments during 2022 aimed at reflecting inflationary effects, along with successful upsell efforts. Additionally, revenue growth was supported by our international operations and techfin business.

Turkcell Turkey revenues, comprising 78% of Group revenues, rose 69.7% year-on-year in Q123 to TRY13,491 million (TRY7,950 million).

Consumer segment revenues rose 67.6% year-on-year on the back of an expanded postpaid subscriber base and price adjustments to offset the impact of inflation.

Corporate segment revenues grew 85.1% year-on-year driven by the performance of digital business services, which grew 103.9% year-on-year.

Standalone digital services revenues registered as part of the consumer and corporate segments rose 65.2% year-on-year in Q123. The primary drivers of this growth were the increased number of stand-alone paid users and adjustments to the prices of services.

Wholesale revenues increased by 53.3% year-on-year to TRY894 million (TRY583 million), driven mainly by the positive impact of currency movements, as well as the traffic increase and capacity upgrades of customers.

Turkcell International revenues, comprising 11% of Group revenues, rose 31.0% year-on-year to TRY1,869 million (TRY1,427 million) due mainly to lifecell’s performance.

Techfin segment revenues, comprising 4% of Group revenues, rose 71.7% year-on-year to TRY606 million (TRY353 million). This was driven by a 79.4% rise in Paycell revenues and 64.6% growth in Financell revenues. Please refer to the Techfin section for details.

Other subsidiaries' revenues, at 8% of Group revenues, including mainly consumer electronics sales revenues, digital channels, non-group call center and energy business revenues, were up 35.7% year-on-year to TRY1,310 million (TRY966 million).

Cost of revenue (excluding depreciation and amortization) decreased to 51.2% (51.4%) as a percentage of revenues in Q123. This was driven mainly by the decline in interconnection cost (2.2pp), despite the increase in employee expenses (1.6pp) and other cost items (0.4pp) as a percentage of revenues.

Administrative expenses increased to 3.2% (2.8%) as a percentage of revenues in Q123.

Selling and marketing expenses rose to 5.3% (5.1%) as a percentage of revenues in Q123. This was driven mainly by the increase in employee expenses (0.7pp) and energy expenses (0.1pp), despite the decline in selling expenses (0.4pp) and marketing expenses (0.2pp) as a percentage of revenues.

Net impairment losses on financial and contract assets was at 1.2% (0.5%) as a percentage of revenues in Q123.

EBITDA¹ rose by 57.1% year-on-year in Q123 leading to an EBITDA margin of 39.1% (40.2%).

The EBITDA of other subsidiaries decreased by 6.0% to TRY113 million (TRY121 million).

Depreciation and amortization expenses increased 28.8% year-on-year in Q123.

Net finance expense decreased to TRY2,104 million (TRY3,038 million) in Q123. This was driven mainly by lower FX losses from borrowings and issued bonds.

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

Net other operating income decreased to TRY1,071 million (TRY1,494 million) in Q123.

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

Net investment activity income was TRY510 million in Q123 compared to TRY299 million in Q122.

Income tax expense increased to TRY740 million (TRY146 million) due mainly to a higher deferred tax expense

incurred in Q123.

Net income of the Group increased by 250.8% to TRY2,817 million (TRY803 million) in Q123. This was driven mainly by robust topline growth on the back of strong operational performance, lower fx losses from borrowings and issued bonds in addition to positive impact from currency-protected time deposits.

Total cash & debt: Consolidated cash as of March 31, 2023 increased to TRY27,317 million from TRY25,961 million as of December 31, 2022. This was driven mainly by the positive impact of currency movements. Excluding FX swap transactions, 57% of our cash is in US$, 15% in EUR, and 26% in TRY.

Please note that 44% of our consolidated debt is in US$, 26% in EUR, 2% in CNY, 5% in UAH, and 22% in TRY.

Net debt¹ as of March 31, 2023 was at TRY23,166 million with a net debt to EBITDA ratio of 0.9 times. Excluding finance company consumer loans, our telco only net debt was at TRY19,284 million with a leverage of 0.8 times.

Turkcell Group had a short FX position of US$31 million as at the end of the first quarter. (Please note that this figure takes hedging portfolio and advance payments into account).

(1) Superbox subscribers are included in mobile subscribers.

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

Despite the negative impact of the earthquake, Turkcell Turkey subscriber base grew by 48 thousand net additions in Q123 to 41.7 million. On the mobile front, our subscriber base was at 37.5 million with 24 thousand net loss in the first quarter of 2023. Accordingly, postpaid subscribers reached 69.1% (66.7%) of the mobile subscriber base. During the quarter, our prepaid customers decreased by 367 thousand. This was due to the disconnection of 509 thousand prepaid customers in Q123 in accordance with the ICTA regulation because of significant tourist arrivals in Q322.

On the fixed front, our fiber subscriber base increased by 38 thousand net additions in Q123 supported by sustained demand for high-speed and quality broadband connections. Total fixed subscribers reached 3.0 million on 44 thousand quarterly net additions. Meanwhile, IPTV customers reached 1.3 million on 28 thousand quarterly net additions in Q123.

The average monthly mobile churn rate was at 1.7% in Q123. Meanwhile, the average monthly fixed churn rate was at 1.5% in Q123. Our customer-oriented approach and advanced analytic capabilities led to improved customer retention performance in both the mobile and fixed segments. This played a crucial role in maintaining a healthy level of churn.

Despite the negative impact of the earthquake, our mobile ARPU (excluding M2M) exceeded the average of inflation rate and rose by 67.9% year-on-year in Q123 driven mainly by price adjustments, upsell to higher tariffs and a larger postpaid subscriber base.

Our residential fiber ARPU growth was 31.4% year-on-year in Q123 due mainly to upselling our customers to higher tariffs. The earthquake had a negative impact on the gradual growth of our residential fiber ARPU.

Average monthly mobile data usage per user grew by 20.9% in Q123 to 16.2 GB with the increasing number and data consumption of 4.5G users. Accordingly, the average mobile data usage of 4.5G users reached 17.4 GB in Q123.

Total smartphone penetration on our network reached 88% in Q123 on a 1.5pp year-on-year improvement. 93% of those smartphones were 4.5G compatible.

lifecell (Ukraine) revenues rose 16.5% year-on-year in Q123 in local currency terms. The growth in revenue is primarily driven by the increase in ARPU, which has been supported by the price adjustments. lifecell’s EBITDA grew 24.2% year-on-year leading to an EBITDA margin of 59.7% improving 3.7pp year-on-year on the back of lower international interconnection expenses. In Q123, lifecell's positive net income was driven by strong topline performance.

lifecell revenues in TRY terms increased 24.6% year-on-year in Q123 with strong operational performance. lifecell’s EBITDA in TRY terms grew by 32.8%, leading to an EBITDA margin of 59.7%.

(2) We may occasionally offer campaigns and tariff schemes that have an active subscriber life differing from the one that we normally use to deactivate subscribers and calculate churn.

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

The three-month active subscriber base of lifecell increased to 8.6 million in Q123 compared to previous quarter. Meanwhile, lifecell’s 3-month active ARPU growth was 24.1% year-on-year on the back of price adjustments. As of Q123, lifecell maintained its leadership in the Ukrainian market with 84.6% smartphone penetration.

lifecell remained focused on employee safety and providing services to Ukrainian customers, with a largely operational network. On average, around 15% of nearly 9 thousand sites are temporarily down as of March 31, 2023 on a daily basis. The conditions of sites in occupied territories are unclear. On average, approximately 92% of our stores nationwide were open daily as of the end of March. Moreover, country’s ICT systems, including payment and CRM, are functioning normally, and the country's banking system is operating without any issues. Additionally, with its improved cash generation, the company’s net debt decreased 54% year-on-year, and lifecell's current cash position is sufficient to maintain its operations.

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

BeST revenues increased 14.6% year-on-year in local currency terms in Q123 supported by ARPU growth and upsell to higher tariffs. Due to the positive impact of the asymmetric mobile termination rates (MTRs), which came into effect on December 31, 2022, the EBITDA margin improved 15.2pp compared to Q122. BeST’s revenues in TRY terms increased 53.2% year-on-year in Q123 with an EBITDA margin of 46.3%.

TECHFIN

Paycell Financial Data (million TRY)	Q122	Q422	Q123	*y/y%*	*q/q%*

Net Income	49.1	83.3	78.8	60.5%	(5.4%)

In Q123, Paycell registered a 79.4% year-on-year increase in revenue due to the sustained demand for digital payment services. This demand was addressed through our diversified product portfolio, which includes mobile payment services, POS solutions, and Paycell card, particularly the Pay Later solution. Paycell's EBITDA increased by 69.0% year-on-year, resulting in an EBITDA margin of 41.9% in the first quarter of 2023.

On the operational front, the quarterly transaction volume (non-group) of Pay Later service doubled year-on-year to TRY1.4 billion, which was utilized by 3-month active Pay Later users of 5.2 million in Q123. Meanwhile, the Paycell Card transaction volume almost doubled year-on-year to TRY2.8 billion in Q123. Additionally, in Q123 the transaction volume of POS solutions almost quintupled year-on-year to TRY10.1 billion supported by the Togg project (presale payments collected through Paycell wallet), Turkey’s first domestic car designed as an electric vehicle, which marks an important and powerful initiative in the mobility sector. Paycell also maintained its position as a marketplace for the trading of gold, silver, and platinum in Q123. Overall, Paycell's total transaction volume across all services almost tripled to TRY18.2 billion year-on-year, driven mainly by a 12% year-on-year rise in Paycell’s total 3-month active users to 7.7 million, and their increased usage.

Financell¹ Financial Data (million TRY)	Q122	Q422	Q123	*y/y%*	*q/q%*

Net Income	67.1	98.4	108.9	62.3%	10.7%

Financell’s revenue grew by 64.6% year-on-year in Q123. The main factors contributing to this growth were the expansion of the loan portfolio and a higher average interest rate on the portfolio as compared to the same period of last year. Meanwhile, Financell reported EBITDA growth of 20.4% year-on-year, resulting in an EBITDA margin of 42.1% in Q123. The decrease in EBITDA margin was due to higher funding costs compared to the Q122. Financell's net income increased 62.3% year-on-year.

Financell’s loan portfolio increased to TRY3.9 billion at the end of Q123. Despite the continued installment limitation on consumer loans for telecom devices, the loan portfolio was supported by higher lending to corporate customers and greater mobility. Accordingly, Financell has extended loans to over 24 thousand corporate customers. Financell's higher loan portfolio, lower receivable sales, and the negative effects of earthquake were the main drivers behind the increase in its cost of risk from 1.0% in Q422 to 2.7% in Q123.

(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.

(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 PRESENTATION OF FINANCIAL STATEMENTS

2.1

Basis of Presentation

The Group prepared its interim condensed financial statements as of and for the three month interim period ended 31 March 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 7 June 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 31 March 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 March 31, 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 January 1, 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.

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. Changes will be applied to accounting estimates or accounting policy changes that occur on or after the effective date.

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.

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 Company / 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.

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

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.

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.

New standards and interpretations (cont’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.

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.

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. 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.

Turkcell’s Contingent Assets and Liabilities

The following disclosures comprise of material legal lawsuits, investigations and in-depth investigations against the Company as of the three month interim period ended 31 March 2023.

Disputes on Special Communication Tax and Value Added Tax

SCT Investigation of 2011

The Large Taxpayers Office levied Special Communication Tax (SCT) and tax penalty on the Company as a result of the Tax Investigation for the year 2011. The Company filed lawsuits for the cancellation of the notification regarding the aforementioned SCT assessment. The court partially accepted and partially rejected the cases and the parties appealed the decisions regarding the parts against them. The Large Taxpayers Office has collected TL 80,355 calculated for the parts against the Company for the assessment of the SCT for the year 2011 by offsetting the receivables of the Company from Public Administrations. While the cases are pending before the court of appeal the Company filed application for the restructuring as per Law no. 6736. The tax Office has rejected the application. The Company has also filed a case for the cancellation of aforementioned rejection act of the Tax Office. In this case, with the decision that notified to the Company on 14 April 2020, the Council of State decided to cancel the rejection act regarding the application for the restructuring. The Large Taxpayers Office and Ministry of Treasury and Finance appealed the decision. The Company replied the appeal request in due time. As a result of the appeal process, The Council of State Plenary Session of the Tax Law Chambers, approved the first instance court decision in favor of the Company with its definitive judgment. Thus, the case was finalized in favor of the Company, the assessment of the SCT for the year 2011 was structured within the scope of Law No. 6736 and TL 47,534 overpaid amount was returned to the Company in 2021 by deduction from the debts of the Company to the State. On the other hand, upon the favorable decision taken in this case, a lawsuit was filed for the cancellation of the tacit rejection of the restructure request of the SCT assessment with tax penalty for the period 2011 within the scope of Law No. 6736 and request of collection of TL 47,405 principal receivable and TL 36,000 damage accrued with a deferment interest until the collection date. The Court partially accepted the case; and decided to cancel the tacit rejection act for the TL 47,269 part, and to return this amount to the Company together with the interest to be calculated at the deferred interest rate determined in accordance with the Law No. 6183 as of the collection date. The parties appealed the decision before Regional Administrative Court regarding the parts against them.

In the cases regarding the cancellation of the SCT assessment for the year 2011, Council of State accepted the appeal and decided to reverse the first instance court decisions in favor of the Company, on the ground that; in the case filed for the cancellation of the rejection act regarding the request to restructure the cases filed for the year 2011, the court decided in favor of the Company and since the mentioned case will affect these cases, finalization of the respective decision should be waited. The Large Taxpayers Office applied for the correction of the decisions. The Company replied to application for the correction of the decisions. The Council of State, rejected the correction of decision requests of the Large Taxpayers Office, in favor of the Company. In 2021, The Court decided there is no need to make ruling regarding the essence of the cases, due to the fact that the amount of the SCT assessment for the year 2011, which are the subject of the lawsuit, was structured within the scope of the Law No. 6736.

Disputes regarding the Law on the Protection of Competition

The investigation initiated by the Competition Board with respect to the practices of the Company regarding the distributors and their dealers in the distribution network. As a result of the investigation the Competition Board rejected the claims that Turkcell determined the resale price. But with the same decision, The Competition Board decided to apply administrative fine on the Company amounting to TL 91,942, on the ground that the Company forced its sub dealers to actual exclusivity. The Company filed a lawsuit on 8 December 2011 for the stay of execution and cancellation of the aforementioned Board decisions regarding the parts against itself. The Court rejected the case. The Company appealed the decision, but the Council of State Plenary Session of the Chambers for Administrative Cases decided to approve the first instance court’s decision. The Company made an individual application to the Constitutional Court, against the respective decision within due time. The Constitutional Court process is pending.

Also, the Large Taxpayers Office issued a payment order regarding the aforementioned administrative fine. The Company has not made any payments and filed a lawsuit for the stay of execution and cancellation of the payment order. The Court accepted the case. The Large Taxpayers Office appealed the decision. As a result of the appeal process, due to the reverse decision of the Council of State about the first instance court decision, the case file was sent to the first instance court. The Court rejected the case. The Company appealed the decision. The appeal process is pending.

TL 47,780 part of the administrative fine amounting to TL 91,942 has been deducted from the receivables that the Company has earned in the case of cancellation of the application for restructuring the 2011 SCT assessment within the scope of Law No. 6736 in 2021. The remaining TL 44,162 part of the administrative fine was paid in April 2022 upon the request of the administration.

Three private companies filed a lawsuits against the Company in relation with this case claiming in total of TL 112,084 together with up to 3 times of the loss amount to be determined by the court for its material damages by reserving its rights for surpluses allegedly.

Among these cases, in the case filed for the compensation of total TL 110,484 material damages together with compensation amounting to three times of the damage and interest, the court decided to reject the case in favor of the Company, at the hearing on 12 June 2019. The plaintiff appealed the case before Regional Court of Justice. The Regional Court of Justice decided to revoke the decision of the first instance court, stating that a new decision should be made after the procedural actions within the scope of the file were re-executed and the expert report was received. The expert report has been submitted to its file, and the Company has submitted its statements and objections regarding the report in due time.

In accordance with our objections, The Court decided to obtain an expert report from a new expert committee, mentioning that there was a clear contradiction between the expert reports in the case. The expert report within this scope has been submitted to its file, and the Company has submitted its statements and objections regarding the report in due time. During the hearing of the case dated 22 June 2022, the court partially accepted the case and ruled reimbursement of TL 215,555 (three times of the actual damage of TL 71,851 loss pursuant to the Act on Protection of Competition, including TL 40,600 previous year loss, TL 14,335 fixed asset loss, TL 14,163 leasing, exchange difference and financing loss, and TL 2,751 profit loss) together with the discount interest applicable from the date of the case to Demirören Dağıtım Satış Pazarlama Matbaacılık ve Tahsilat Sistemleri A.Ş, June 2012, and partially rejected the case for the remaining part.

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 technique
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 44,874 lower as of 31 March 2023 (31 December 2022: TL 15,892).

As of 31 March 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:

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.

SUBSEQUENT EVENTS

As per the decision of the Company’s Board of Directors dated 13 April 2023; it has been decided on the acquisition of the 33.3% share of Sofra by the Company’s 100% owned subsidiary Turkcell Ödeme, which has 33.3% shareholding in it, from Belbim Elektronik Para ve Odeme Hizmetleri A.S., one of the other shareholders of Sofra, for TL 763, by exercising its pre-emption right pursuant to the existing Shareholders Agreement.
