COMMENTS BY CEO, ALİ TAHA KOÇ, PhD

Resuming the Real Growth Path

As we celebrate our 30^th^ anniversary at Turkcell Group, we remain committed to creating value for our stakeholders through strong foundations and an innovative vision. In line with our strategic goals, we took a significant step by completing the sale of our assets in Ukraine on September 9, 2024. The proceeds from this transaction have been reflected in our third-quarter financial results.

We have proudly led Türkiye's digitalization journey for over 30 years. We will now share our expertise and vision on the global stage. With my recent election to the board of directors of GSMA, the global GSM association, I am honored to represent not just the Turkcell brand but also Türkiye. We will continue to make significant contributions to the mobile communications sector and the broader digital landscape under the GSMA umbrella.

We continue the renewable energy investments in line with our plans. Recently, we completed the first phase of our solar energy investments, installing 54 MW of power, with 6.4 MW already activated in the third quarter. Following the acquisition of the necessary permits, we will progressively bring the remaining capacity online.

We delivered a strong quarter, driven by a robust ARPU performance of Turkcell Türkiye, an expanding postpaid subscriber base, and contributions from our Techfin business. In the third quarter of 2024, our group revenues rose by 6.9% on an annual basis to TRY 40.2 billion, while our EBITDA^1^ margin increased by 1.4 points to 44.2% despite the wage increase we made to protect the purchasing power of our employees, who are our focus of value. Our net income reached TRY 14.3 billion, with our strong operations, which contributed TRY 3.1 billion, along with the proceeds from the asset sale in Ukraine. In the third quarter, Turkcell Türkiye's subscriber base increased by 322 thousand to 43.5 million.

Despite the aggressive competition, we achievedstrong operational results

In the third quarter, we continued to deliver a strong operational performance. We gained a net of 515 thousand postpaid subscribers, bringing our total net additions in the last 12 months to 1.9 million. As a result, the share of our postpaid subscriber base grew by 4 percentage points year-on-year, reaching 74%. Thanks to our expanding postpaid subscriber base, price adjustments, and successful upsell, our Mobile ARPU^2^ growth increased to 6.9% year-over-year. Since May, we have observed increased activity in the Mobile Number Portability (MNP) market due to the aggressive pricing actions of competitors. This trend intensified further in the third quarter as competition heightened. Increased competition, along with seasonality, resulted in a mobile churn rate of 2.2% for the third quarter.

In line with our customer-focused approach, we introduced our '30^th^ Year 1000 Mbps Speed ​​Campaign' to our fixed broadband customers in September. In the fixed broadband segment, we remain focused on fiber subscribers, having gained 47 thousand net subscribers thanks to the strong demand for our high-speed and end-to-end fiber service, while our subscriber base exceeded 2.4 million. The share of our 12-month contract packages, implemented to mitigate the effects of inflation, increased by 23 percentage points year-on-year among our residential fiber subscribers, reaching 82%. In the third quarter of 2024, our residential fiber ARPU rose 15.1% year-on-year thanks to the increasing 12-month contract subscriber share, upsell strategy and price adjustments in fixed broadband services and IPTV.

Our Techfin business continues to supportfinancial performance

Our strategic focus area, Techfin, which includes our Financell^3^ and Paycell brands, continued to support group revenue strongly in the third quarter. Financell grew by 38.1% on an annual basis, recording a revenue of TRY 1.1 billion, supported by the increase in average interest rates, while the net interest margin of 4.1% continued to improve. On the other hand, Paycell revenues grew by 19.6%, reaching TRY 970 million, driven by the high demand for our POS solutions and the increasing volume of Paycell Card. The transaction volume of the "Pay Later" mobile payment service, which has the largest share in Paycell revenues, increased by 24% (non-group) to TRY 3.1 billion. Since its launch, our POS solutions have exceeded demand expectations, maintaining a strong performance with an 86% increase in transaction volume.

The number of standalone paid users of our digital services^4^ decreased by 14% year-on-year, reaching 5.0 million, in line with our expectations as we prioritized profitability. Meanwhile, our TV+ platform, which has consistently expanded its market share since its launch, has now become the second-largest player in the market, according to the ICTA's second-quarter report.

5

In our Digital Business Services portfolio, the revenues from our four next-generation data centers, with a total IT capacity of 55 MW –33 MW of which is active—and cloud services offering value-added services, grew by 43% in the third quarter, reaching TRY 639 million. We are committed to expanding the capacity of our data centers, which will remain a key strategic priority in the years ahead.

We revise our guidance

Due to higher-than-expected inflation in the second half of the year, we have revised our year-end inflation forecast upwards. Accordingly, we are updating our revenue growth target^5^for 2024 to approximately 7%. We maintain our EBITDA margin expectation at approximately 42% and our operational capex to sales^6^ratio target at approximately 23%.

I extend my heartfelt thanks to all our employees for their contributions to our success and express my gratitude to our Board of Directors for their continued support.

(1) EBITDA is a non-GAAP financial measure. See page 14 for the explanation of how we calculate Adjusted EBITDA and its reconciliation to net income

(2) Excluding M2M

(3) Following the change in organizational structure, the revenues of Turkcell Sigorta Aracılık Hizmetleri A.Ş. (Insurance Agency), which was previously managed under Financell, are now classified as "Other" in the Techfin segment as of the first quarter of 2023.

(4) Including IPTV, OTT TV, fizy, lifebox and GAME+

(5) Our expectations for 2024 incorporate the effects of inflation accounting under IAS 29. These projections are based on assumptions regarding factors beyond our control, including key macroeconomic indicators such as inflation. Specifically, we are assuming an annual inflation rate of 43%, applied on a monthly basis, (previous estimate: 37)%. This paragraph contains forward-looking statements that reflect our current estimates and expectations regarding market conditions across all of our businesses. However, there can be no assurance that these forward-looking statements will occur as anticipated. For a discussion of the various factors that could impact the outcome of these forward-looking statements, please refer to our 2023 annual report on Form 20-F filed with the SEC, specifically the risk factors section.

Revenue of the Group rose 6.9% year-on-year in Q324. This was mainly driven by Turkcell Türkiye’s strong performance supported by a larger postpaid subscriber base that generates more ARPU than prepaid subscribers, upsell efforts and a solid increase in fixed segment ARPU. The Techfin segment’s solid revenue growth of 30.9% also supported the Group revenue increase.

Turkcell Türkiye revenues, comprising 87% of Group revenues, rose 7.1% year-on-year to TRY34,854 million (TRY32,550 million).

- Consumer segment^4^ revenues grew<br> 10.8% year-on-year on the back of rising postpaid subscriber share, price adjustments, and<br> upsell efforts.
- Corporate segment^4^ revenues declined<br> by 1.4% year-on-year. Constrained demand in the tightening economic environment negatively<br> impacted the hardware revenues of digital business services, which declined by 44.1% year-on-year.<br> Recurring service revenues rose 18% year on year.

(4) Following the change in organizational structure, the revenues from sole proprietorship subscribers that we define as Merchant, which were previously managed under the Corporate segment, are being reported under the Consumer segment as of and from the third quarter of 2023. Within this scope, past data has been revised for comparative purposes.

7

- Standalone digital services revenues across<br> consumer and corporate segments rose 4% year-on-year, primarily attributed to price adjustments,<br> despite the continued shrinkage of the paid user base in consequence of our profitability-focused<br> strategy.
- Wholesale revenues were down 9.9% year-on-year<br> to TRY2,378 million (TRY2,639 million), resulting from alternative data solutions in the<br> market.
--- ---

Turkcell International^1^revenues, comprising 2% of Group revenues, rose 20.6% to TRY935 million (TRY775 million).


Techfin segment revenues, comprising 5% of Group revenues, were up 30.9% year-on-year to TRY2,132 million (TRY1,629 million). Financell’s revenue grew 38.1%, and Paycell’s revenues increased 19.6% year-on-year. Please refer to the Techfin section for details.

Other segment revenues, at 6% of Group revenues, which mostly include non-group call center and energy business revenues and consumer electronics sales revenues, declined 14.6% year-on-year to TRY2,251 million (TRY2,636 million). This was primarily caused by weak demand for consumer electronics.


Cost of revenue (excluding depreciation and amortization) decreased to 44.8% (47.8)% as a percentage of revenues in Q324. The decline in the cost of goods sold (2.2pp), interconnection cost (1.1pp), and other cost items (1.2pp) outweighed the rise in personnel expenses (0.9pp) and funding cost (0.6pp) as a percentage of revenues.

Administrative Expenses increased to 4.1% (3.2)% as a percentage of revenues in Q324. This was mainly led by higher employee expenses (0.7pp) as a percentage of revenues.


Selling and Marketing Expenses increased to 6.3% (5.4)% as a percentage of revenues in Q324, due mainly to the rise in personnel expenses (0.6pp) as a percentage of revenues.

Net impairment losses on financial and contractassets decreased to 0.6% (0.8)% as a percentage of revenues in Q324.


EBITDA^2^ grew 10.4% year-on-year in Q324, leading to an EBITDA margin of 44.2% (42.8)%.

- Turkcell Türkiye’s EBITDA rose<br> 12.6% year-on-year to TRY16,739 million (TRY14,865 million) with an EBITDA margin of 48.0%<br> (45.7)%. The primary contributors to margin improvement were lower interconnection costs<br> and a reduction in cost of goods sold as a percentage of revenues.
- Turkcell International EBITDA declined 1.2%<br> year-on-year to TRY365 million (TRY369 million), leading to an EBITDA margin of 39.1% (47.6)%.<br> The increase in personnel expenses led to a margin dilution.
--- ---
- Techfin segment EBITDA decreased 4.1% year-on-year<br> to TRY595 million (TRY620 million) with an EBITDA margin of 27.9% (38.1)%. This was driven<br> by increases in funding costs for Financell and administrative expenses as a percentage of<br> revenues.
--- ---
- The EBITDA of other subsidiaries was at TRY58<br> million (TRY236 million).
--- ---

Depreciation and amortization expenses increased 8.8% year-on-year in Q324.

Net finance expense of TRY345 million (positive TRY2,187 million) was recorded for Q324, including a TRY1.5 billion monetary gain and net FX losses of TRY1.8 billion.

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

Other expenses decreased to TRY179 million (TRY2,916 million) in Q324.


Income tax expense was TRY2,290 million (TRY9,764 million) in this quarter. Higher corporate tax was more than offset by lower deferred tax expenses.

(1) As per our Company’s announcement on September 9, 2024, we no longer hold any shares in companies operating in Ukraine as of Q324.

In Q324, Turkcell Türkiye experienced a net increase of 322 thousand subscribers, resulting in a total subscriber base of 43.5 million. The mobile subscriber base totaled 38.7 million, with a net add of 250 thousand in this quarter. Our commitment to expanding our postpaid subscriber base, coupled with successful switch performance, led to a quarterly net add of 515 thousand postpaid subscribers. Over the first nine months of the year, we recorded net adds of 1.5 million postpaid subscribers. Accordingly, postpaid subscribers account for 73.9% (69.8)% of our mobile segment as of the end of Q324. Despite the high tourist activity during the summer months, our prepaid customer base contracted by 266 thousand during the quarter. This reduction can be primarily attributed to the widespread usage of alternative data solutions (eSIM technology).

As the market leader in the mobile segment, we prioritize market rationalization. Nevertheless, we have faced aggressive pricing actions from competitors since May 2024, leading to high volatility in the MNP (Mobile Number Portability) market which increased by 47% compared to the previous quarter. Accordingly, the average monthly mobile churn rate slightly increased to 2.2% in Q324. Please recall that the innovative campaigns, primarily the “30^th^ Anniversary Double-Up,” as well as Ramadan and Eid holidays, contributed to the previous quarter’s churn rate. Our mobile ARPU (excluding M2M) rose 6.9% year-on-year, driven mainly by a rising postpaid subscriber base, price adjustments, and upsell efforts.

In the fixed business, our subscriber base exceeded 3.2 million on 44 thousand quarterly net additions. Thanks to our fiber focus, the fiber subscriber base grew by 47 thousand in this quarter. Residential fiber ARPU growth was 15.1% year-on-year in Q324 due to an increase in the share of 12-month contract subscribers and expanding high-speed tariffs’ share, price adjustments, and premium pricing in IPTV. The average monthly fixed churn rate remained steady at 1.6% in Q324 on a yearly basis.

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

BeSTrevenues grew 25.6% year-on-year in Q324 in local currency terms, driven by a rise in data, voice revenues, and bulk-SMS in Q324. BeST’s EBITDA grew 23.9% year-on-year, resulting in an EBITDA margin of 45.0%. BeST’s revenues in TRY terms rose 41.6% year-on-year in Q324.

BeST continued to offer LTE services to all six regions, encompassing 4.4 thousand sites in Q324. Enhanced LTE coverage has enabled BeST to expand its 4G subscriber base. Accordingly, 4G users reached 85% of the 3-month active subscriber base, which continued to support mobile data consumption and digital services usage. Additionally, the average monthly data usage among 4G subscribers increased 7% year-on-year, reaching 20.4 GB in Q324.

Paycell has seen another quarter of robust financial results. Revenues grew by 19.6% year-on-year in the quarter. The main drivers of this performance were POS solutions and prepaid card & money transactions, thanks to increasing volume and commission. Paycell’s EBITDA rose 9.2% year-on-year, resulting in an EBITDA margin of 45.0% in Q324.

Strong momentum on the POS solution has continued in this quarter, resulting in an 86% volume increase on a yearly basis. The Pay Later service, the revenues of which account for 56% of the Paycell topline, reached a TRY3.1 billion transaction volume (non-group) in Q324, up 24% year-on-year. 3-month active Pay Later users grew by 5% to 6.2 million. Moreover, the Paycell card transaction volume experienced robust growth, rising 87% year-on-year to TRY7.4 billion. Meanwhile, the total transaction volume across all services expanded by 46% to TRY26.7 billion year-on-year in Q324.

(1) Following the change in the organizational structure, the revenues of Turkcell Sigorta Aracılık Hizmetleri A.Ş. (Insurance Agency), which was previously managed under Financell, have been reclassified from Financell to "Other" in the Techfin segment as of the first quarter of 2023.

Financell’s revenues rose 38.1% year-on-year in Q324, driven mainly by the expanding loan portfolio, as well as the higher average interest rate on the loan portfolio when compared to the same period of the last year. EBITDA margin realized at 18.5%.

Financell’s loan portfolio was at TRY6.3 billion in Q324. Financell’s cost of risk was at 2.8% at the end of the quarter. As we emphasized in the previous quarter, Financell began offering loans at varying rates based on customers’ individual risk profiles. This approach not only improves customer access and financial inclusion, but also mitigates the negative impact of installment limitations on consumer loans for smartphones above TRY12,000 threshold.

**RECONCILIATION OF NON-GAAP FINANCIAL MEASUREMENTS:**We believe Adjusted EBITDA, among other measures, facilitates performance comparisons from period to period and management decisionmaking. It also facilitates performance comparisons from company to company. Adjusted EBITDA as a performance measure eliminates potentialdifferences caused by variations in capital structures (affecting interest expense), tax positions (such as the impact of changes ineffective tax rates on periods or companies) and the age and book depreciation of tangible and intangible assets (affecting relativedepreciation expense and amortization expense). We also present Adjusted EBITDA because we believe it is frequently used by securitiesanalysts, investors and other interested parties in evaluating the performance of other mobile operators in the telecommunications industryin 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 losseson financial and contract assets, but excludes finance income and expense, other operating income and expense, investment activity incomeand expense, share of profit of equity accounted investees and minority interest.

Nevertheless, Adjusted EBITDA has limitationsas 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 IFRS. The following table provides a reconciliation of Adjusted EBITDA, as calculated using financial data preparedin accordance with IFRS to net profit, which we believe is the most directly comparable financial measure calculated and presented inaccordance with IFRS.

RECONCILIATION OF ARPU: ARPU is anoperational measurement tool and the methodology for calculating performance measures such as ARPU varies substantially among operatorsand is not standardized across the telecommunications industry, and reported performance measures thus vary from those that may resultfrom the use of a single methodology. Management believes this measure is helpful in assessing the development of our services over time.The following table shows the reconciliation of Turkcell Türkiye revenues to such revenues included in the ARPU calculations forQ3 2023 and Q3 2024.

New standards and interpretations

The accounting policies and presentation are consistent with those of the previous financial year and corresponding interim reporting period, except for the adoption of new standards effective as of 1 January 2024. The effects of these standards and interpretations on the Group’s financial position and performance have been disclosed in the related paragraphs. The Group has not early adopted any standard, interpretation or amendment that has been issued but is not yet effective.

i) The new standards, amendments and interpretations which are effective as of 1 January 2024 are as follows:

Amendmentsto IAS 1- Classification of Liabilities as Current and Non-Current Liabilities

In January 2020 and October 2022, IASB issued amendments to IAS 1 to specify the requirements for classifying liabilities as current or non-current. According to the amendments made in October 2022 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, October 2022 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 clarify that the requirement for the right to exist at the end of the reporting period applies to covenants which the entity is required to comply with on or before the reporting date regardless of whether the lender tests for compliance at that date or at a later date. The amendments also 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 must be applied retrospectively in accordance with IAS 8.

The amendments did not have a significant impact on the financial position or performance of the Group.

Amendmentsto IFRS 16 - Lease Liability in a Sale and Leaseback

In September 2022, the IASB issued amendments to IFRS 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 recognize any amount of the gain or loss that relates to the right of use it retains. In applying requirements of IFRS 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 recognize 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 IFRS 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 IAS 8. A seller-lessee applies the amendments retrospectively in accordance with IAS 8 to sale and leaseback transactions entered into after the date of initial application of IFRS 16.

The amendments did not have a significant impact on the financial position or performance of the Group.

New standards and interpretations(continued)

i) The new standards, amendments and interpretations which are effective as of 1 January 2024 are as follows: (continued)

Amendmentsto 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 transition rules clarify that an entity is not required to provide the disclosures in any interim periods in the year of initial application of the amendments. Thus, the amendments had no impact on the Group’s interim condensed consolidated financial statements.

ii) Standards, amendments and interpretations that are issued but not yet effective:

Standards, interpretations and amendments to existing standards that are issued but not yet effective up to the date of issuance of the interim condensed 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.

Amendmentsto IFRS 10 and IAS 28 - Sale or Contribution of Assets between an Investor and its Associate or Joint Venture

In December 2015, IASB 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.

Amendmentsto IAS 21 - Lack of exchangeability

In August 2023, the Board issued amendments to IAS 21. The amendments specify how an entity should assess whether a currency is exchangeable and how it should determine a spot exchange rate when exchangeability is lacking. When an entity estimates a spot exchange rate because a currency is not exchangeable into another currency, it discloses information that enables users of its financial statements to understand how the currency not being exchangeable into the other currency affects, or is expected to affect, the entity’s financial performance, financial position and cash flows. The amendments will be effective for annual reporting periods beginning on or after 1 January 2025. Early adoption is permitted but will need to be disclosed. When applying the amendments, an entity cannot restate comparative information.

The Group expects no significant impact on its balance sheet and equity.

ii) Standards, amendments and interpretations that are issued but not yet effective: (continued)

Amendmentsto IFRS 9 and IFRS 7 – Classification and measurement of financial instruments

In May 2024, the Board issued amendments to the classification and measurement of financial instruments (amendments to IFRS 9 and IFRS 7). The amendment clarifies that a financial liability is derecognised on the ‘settlement date’. It also introduces an accounting policy option to derecognise financial liabilities that are settled through an electronic payment system before settlement date if certain conditions are met. The amendment also clarified how to assess the contractual cash flow characteristics of financial assets that include environmental, social and governance (ESG)-linked features and other similar contingent features as well as the treatment of non-recourse assets and contractually linked instruments. Additional disclosures in IFRS 7 for financial assets and liabilities with contractual terms that reference a contingent event (including those that are ESG-linked), and equity instruments classified at fair value through other comprehensive income are added with the amendment. The amendment will be effective for annual periods beginning on or after 1 January 2026. Entities can early adopt the amendments that relate to the classification of financial assets plus the related disclosures and apply the other amendments later. The new requirements will be applied retrospectively with an adjustment to opening retained earnings.

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

IFRS 18 – The new Standardfor Presentation and Disclosure in Financial Statements

In April 2024, IASB issued IFRS 18 which replaces IAS 1. IFRS 18 introduces new requirements on presentation within the statement of profit or loss, including specified totals and subtotals. IFRS 18 requires an entity to classify all income and expenses within its statement of profit or loss into one of five categories: operating; investing; financing; income taxes; and discontinued operations. It also requires disclosure of management-defined performance measures and includes new requirements for aggregation and disaggregation of financial information based on the identified ‘roles’ of the primary financial statements and the notes. In addition, there are consequential amendments to other accounting standards, such as IAS 7, IAS 8 and IAS 34. IFRS 18 and the related amendments are effective for reporting periods beginning on or after 1 January 2027, but earlier application is permitted. IFRS 18 will be applied retrospectively.

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

IFRS 19 – Subsidiaries withoutPublic Accountability: Disclosures

In May 2024, the Board issued IFRS 19, which allows eligible entities to elect to apply reduced disclosure requirements while still applying the recognition, measurement and presentation requirements in other IFRS accounting standards. Unless otherwise specified, eligible entities that elect to apply IFRS 19 will not need to apply the disclosure requirements in other IFRS accounting standards. An entity that is a subsidiary, does not have public accountability and has a parent (either ultimate or intermediate) which prepares consolidated financial statements, available for public use, which comply with IFRS accounting standards may elect to apply IFRS 19. IFRS 19 is effective for reporting periods beginning on or after 1 January 2027 and earlier adoption is permitted. If an eligible entity chooses to apply the standard earlier, it is required to disclose that fact. An entity is required, during the first period (annual and interim) in which it applies the standard, to align the disclosures in the comparative period with the disclosures included in the current period under IFRS 19.

The standard is not applicable for the Group.

Annual Improvements to IFRS AccountingStandards – Volume 11

In July 2024, the IASB issued Annual Improvements to IFRS Accounting Standards – Volume 11, amending the followings:

- IFRS<br> 1 First-time Adoption of International Financial Reporting Standards – Hedge Accounting<br> by a First-time Adopter: These amendments are intended to address potential confusion arising<br> from an inconsistency between the wording in IFRS 1 and the requirements for hedge accounting<br> in IFRS 9.

IFRS 9 has been also amended to remove the reference to 'transaction price”.
--- ---
- IFRS<br> 10 Consolidated Financial Statements – Determination of a 'De Facto Agent': The amendments<br> are intended to remove the inconsistencies between IFRS 10 paragraphs.
--- ---
- IAS<br> 7 Statement of Cash Flows – Cost Method: The amendments remove the term of “cost<br> method” following the prior deletion of the definition of 'cost method'.

iii) The amendments which are effective immediately upon issuance

Amendmentsto IAS 12 - International Tax Reform – Pillar Two Model Rules

In May 2023, the Board 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 temporary exception from recognition and disclosure of information about deferred taxes and the requirement to disclose the application of the exception apply immediately and retrospectively upon issue of the amendments.

Based on management’s assessments, as of 30 September 2024, the amendments due to Pillar Two did not have an impact on its consolidated financial statements. However, the Company will continue to monitoring upcoming legislation changes on this matter, in Turkey and in other countries that the Group operates.

3 Segment information

In accordance with its integrated communication and technology services strategy, Group has reportable segments which are Turkcell Turkiye, Turkcell International and Techfin. While some of these strategic segments offer the same types of services, they are managed separately because they operate in different geographical locations and are affected by different economic conditions.

Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision maker. The chief operating decision maker function is carried out by the Board of Directors, however Board of Directors may transfer the authorities, other than recognized by the law, to the General Manager and other directors.

Turkcell Turkiye reportable segment includes mobile, fixed telecom, digital services and digital business services operations of Turkcell, Turkcell Superonline Iletisim Hizmetleri A.S.

Techfin reportable segment includes all financial services operations of Turkcell Finansman, Turkcell Odeme, Paycell, Paycell Europe, Turkcell Sigorta and Turkcell Dijital Sigorta. The operations of these legal entities aggregated into one reportable segment as the nature of services are similar and most of them share similar economic characteristics.

Fair value ofderivative instruments and risk management

Fair value

This section explains the judgments and estimates made in determining the fair values of the financial instruments that are recognized and measured at fair value in the financial statements. To provide an indication of the reliability of the inputs used in determining fair value, the Group has classified its financial instruments into the three levels prescribed under the accounting standards. An explanation of each level is as follows:

• 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 the asset or liability.

Sensitivityanalysis

The basis for the sensitivity analysis to measure foreign exchange risk is an aggregate corporate-level currency exposure. The aggregate foreign exchange exposure is composed of all assets and liabilities denominated in foreign currencies; the analysis excludes net foreign currency investments.

A 10% strengthening/weakening of the TL, UAH, BYN, EUR against the following currencies as at 30 September 2024 would have increased/(decreased) profit or loss by the amounts shown below. This analysis assumes that all other variables, in particular interest rates, remain constant.
