COMMENTS BY CEO, ALİ TAHA KOÇ, PhD

As Turkcell, the first and only Turkish company to be listed on the Istanbul and New York stock exchanges simultaneously, we celebrated our 30th anniversary on July 8th by ringing the closing bell at the New York Stock Exchange. In our 30th year, we resolutely remain on a path toward transforming our solid foundations and innovative company vision into stakeholder value.

In line with our strategy of creating value from our assets, we continuously evaluate our portfolio and take strategic actions when the right conditions are met. Accordingly, we initiated the sale process for our assets in Ukraine at the end of 2023. Upon the completion of official approval procedures, we successfully executed the share sale on September 9, 2024. We expect the final sale value to be determined by the end of the year, following the closing adjustments of the financial statements. With this transaction, we reaffirm our focus on Türkiye and on a technology-driven approach.

In the second quarter of 2024, the Central Bank of Türkiye's decision to keep the policy interest rate steady, meeting expectations, contributed to a balanced macroeconomic trajectory, while low foreign exchange rate volatility improved predictability in managing our financial risks. Annual inflation, which peaked with a 75.4% increase in May, was recorded at 71.6% in June. Therefore, the growth performance of those companies applying hyperinflation accounting was negatively impacted by high inflation.

Our second quarter consolidated revenues were at TRY 34.9 billion, with EBITDA1 of TRY 14.9 billion, and an EBITDA Margin of 42.6%. We delivered a net income of TRY 2.9 billion, supported by lower foreign exchange rate losses and effective risk management. During the quarter, we had a net add of 346 thousand, reaching a total of 43.2 million subscribers. The strong financial performance of the Techfin segment, one of our strategic focus areas, continued to support our group.

Successful operational results with the lowest mobile churn rate of the past six years

As in 2023, we observed a rational market until May of this year. Yet, after that, the mobile number portability (MNP) market was triggered due to aggressive pricing actions by competitors. As the leader in the mobile segment, we aim for sustainable growth and keep an eye on market rationalization. Although short-term actions leading to unsustainable performance are not among our priorities, we closely monitor changes in market dynamics.

With our customer-focused actions, superior service quality, and value propositions we gained net 474 thousand mobile subscribers in the first half of the year, 245 thousand being in the second quarter. Our postpaid subscriber base rose by a net of 477 thousand this quarter, where the additions of the past 12 months reached 1.8 million. Thanks to our sequential price adjustments, our postpaid subscriber base exceeding 73%, and our ability to upsell our customers, our Mobile ARPU2 rose 5.3% year-on-year.

In line with our strategy of offering innovative and comprehensive solutions based on our customers' needs, we continue to stand by them at all times. Within this scope, we have continued to offer the “Smart Control Service,” which we launched in the first quarter, free of charge. Additionally, we shared the spirit of our 30th anniversary with our customers through the “30th Anniversary Double Up Campaign.” Thanks to our subscriber retention strategy, supported by analytical models, as well as our innovative campaigns and services, our mobile churn rate decreased to 1.5%, the lowest level of the past six years.

In fixed broadband services, we maintained our focus on fiber subscribers. As a result of strong demand for our high-speed, end-to-end fiber service, we gained net 42 thousand subscribers, bringing our fiber subscriber base to 2.4 million for the quarter. Our high-speed fiber internet packages, designed to meet our customers' growing speed requirements, have continued to attract interest. The rate of fiber subscribers opting for speeds of 100 Mbps and above increased to 34% this quarter, with respect to 24% in the same period of last year. Meanwhile, we continued to pursue our 12-month contract strategy to mitigate the effects of inflation. The share of 12-month contract tariffs among our individual fiber subscribers reached 78%. Residential fiber ARPU rose by 6.6% year-on-year in this quarter. Our total fixed broadband subscriber base reached 3.2 million, and our fixed subscriber churn rate, at 1.2%, marked its lowest level since 2006.

The continued strong contribution of Techfin, one of our focus areas

Our techfin business, which we operate under the Financell3 and Paycell brands, continued to contribute significantly to the group growth this quarter. Financell's revenues grew by 33.9% year-on-year to TRY 947 million, driven by an increase in average interest rates, while its loan portfolio reached TRY 6.3 billion at the end of the second quarter. The revenues of Paycell, which provides secure payment solutions, increased by 15.8% year-on-year. The transaction volume of the "Pay Later" service (excluding group companies) grew by 34% to TRY 2.6 billion, while our POS solutions, which have seen high demand since their launch, continued to strengthen their place in our product portfolio with an 86% increase in transaction volume. Our digital service portfolio, including TV+, lifebox, fizy, BiP, and GAME+, allows us to comprehensively impact our customers' lives. With those services, we primarily focus on revenue and profitability. The standalone paid user4 of digital services decreased by 3.8% year-on-year to 5.3 million in the second quarter, while thanks to our pricing actions, revenues from digital services & solutions grew by 4.9%.

We are progressing in line with our strategic goals

In the 30 years since our founding, we have not limited our investments to mobile and fixed infrastructures alone; we have also contributed to a wide range of areas, from people to things, the technology ecosystem to other industries, and from social responsibility to environmental sustainability. That's precisely why, in our 30th year, we say that, “Everything works with Turkcell, and Turkcell works with everyone.”

Meanwhile, in addition to our core focus on “leadership in telecommunications”, we also prioritize data center operations, renewable energy, artificial intelligence technologies, and cybersecurity to further strengthen our position as an “end-to-end technology provider”. And so, by building on our achievements, we will continue without pause to shape a future where technology enriches lives and drives progress.

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 throughout this journey.

FINANCIAL AND OPERATIONAL REVIEW

(1) Excluding depreciation and amortization expenses.

(2) 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.

(3) EBIT is a non-GAAP financial measure and is equal to EBITDA minus depreciation and amortization expenses.

Revenue of the Group decreased by 0.3% year-on-year in Q224. This was mainly attributable to the decreasing demand for large-budget projects in digital business services, resulting in lower hardware revenues on a yearly basis coupled with lower consumer equipment sales.

Turkcell Türkiye revenues, comprising 87% of Group revenues, rose 1.5% year-on-year to TRY30,433 million (TRY29,969 million).

(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.

Turkcell International1 revenues, comprising 3% of Group revenues, rose 2.7% to TRY890 million (TRY867 million).

Techfin segment revenues, comprising 6% of Group revenues, increased 23.5% year-on-year to TRY1,754 million (TRY1,421 million). Financell’s revenue rose 33.9%, and Paycell revenues grew 15.8% year-on-year. Please refer to the Techfin section for details.

Other subsidiaries' revenues, at 6% of Group revenues, which include mostly non-group call center and energy business revenues and consumer electronics sales revenues, decreased 33.8% year-on-year to TRY1,836 million (TRY2,772 million). This was driven primarily by low demand for consumer electronics.

Cost of revenue (excluding depreciation and amortization) decreased to 46.7% (49.2%) as a percentage of revenues in Q224. This was mainly due to the decline in cost of goods sold (6.2pp), interconnection cost (1.0pp), and energy expenses (0.6pp) despite the rise in personnel expenses (3.1pp), funding cost (1.1pp), and other cost items (1.1pp) as a percentage of revenues.

Administrative Expenses increased to 3.4% (2.6%) as a percentage of revenues in Q224 due mainly to the rise in personnel expenses.

Selling and Marketing Expenses increased to 6.5% (4.8%) as a percentage of revenues in Q224, due mainly to the rise in personnel expenses (0.7pp) and marketing expenses (0.9pp) as a percentage of revenues.

Net impairment losses on financial and contract assets decreased to 0.7% (1.0%) as a percentage of revenues in Q224.

EBITDA2 rose 0.3% year-on-year in Q224, leading to an EBITDA margin of 42.6% (42.4%).

Depreciation and amortization expenses increased 3.2% year-on-year in Q224.

Net finance expense of TRY1,489 million (TRY5,482 million) was recorded for Q224, including a TRY1.2 billion monetary gain and net FX losses of TRY2.0 billion.

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

Other expenses decreased to TRY210 million (positive TRY158 million) in Q224.

Income tax expense was positive TRY155 million (TRY935 million) due mainly to deferred tax income and lower corporate tax compared to the previous year.

Profit /(loss) from discontinued operations of TRY528 million (TRY699 million) was recorded in Q224.

Net income of the Group was TRY2.9 billion (negative TRY871 million) in Q224. This resulted mainly from a strong performance at the EBITDA levels, as well as lower FX losses due to stabilized FX rates and the hedging strategy.

Total cash & debt: Consolidated cash as of June 30, 2024, decreased to TRY50,189 million compared to TRY62,341 million as of December 31, 2023. Excluding FX swap transactions, 41% of our cash is in US$, 28% in EUR, 1% in CNY, and 30% in TRY.

(1) As of December 31, 2023, our Lifecell, UkrTower, and Global LLC operations in Ukraine have been classified as a disposal group held for sale and as a discontinued operation. Therefore, this segment does not include revenues from those operations.

(2) 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.

Consolidated debt as of June 30, 2024, decreased to TRY99,191 million from TRY104,882 million as of December 31, 2023. TRY3,051 million of our consolidated debt is comprised of lease obligations. Please note that 41% of our consolidated debt is in US$, 33% in EUR, 3% in CNY, and 23% in TRY.

Net debt1 as of June 30, 2024, increased to TRY32,400 million from TRY29,691 million as of December 31, 2023, with a net debt to EBITDA ratio of 0.6x times.

Turkcell Group had a short FX position of US$123 million at the end of the quarter (Please note that this figure takes hedging portfolio and advance payments into account). The short FX position of US$123 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, were at TRY10,690 million in Q224.

Operational capital expenditures (excluding license fees) at the Group level were at 22.5% of total revenues in Q224.

(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.

Operational Review of Turkcell Türkiye

(1) Including mobile, fixed broadband, IPTV, and wholesale (MVNO&FVNO) subscribers

(2) Superbox subscribers are included in mobile subscribers.

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

Turkcell Türkiye's subscriber base continued its expansion, reaching 43.2 million with a net addition of 346 thousand during the second quarter, largely due to additions in postpaid subscribers. Thanks to our postpaid subscriber focus and successful switch performance, we managed to record a total of 948 thousand postpaid subscriber net additions in the first half of the year.

On the mobile front, our subscriber base reached 38.5 million on 245 thousand quarterly net additions in Q224, driven mainly by 477 thousand net quarterly additions to our postpaid subscriber base. Accordingly, our postpaid subscribers reached 73.1% (69.9%) of our mobile subscriber base as of the end of Q224. Meanwhile, our prepaid subscriber base decreased by 232 thousand in Q224. Although the market was less aggressive compared to previous quarters generally, the competitors launched aggressive campaigns at the end of the second quarter. Our mobile ARPU (excluding M2M) rose by 5.3% year-over-year thanks to price adjustments, a larger postpaid base, and effective upselling performance in Q224. The average monthly mobile churn rate was at 1.5% in Q224, the lowest since 2018, driven by effective churn management supported by analytical models as well as innovative campaigns, primarily “Smart Control Service” and “30th Anniversary Double-Up.”

In the fixed business, our subscriber base expanded to 3.2 million, with a net addition of 46 thousand during the quarter due to our focus on the fiber side, rising demand for pure fiber service, and high-speed packages. Our fiber subscriber base grew by 42 thousand in this quarter. Our residential fiber ARPU growth was 6.6% year-on-year in Q224, driven by rising 12-month contracted subscriber share, price adjustments, and efforts to encourage higher tariff plans as well as higher IPTV pricing. Meanwhile, IPTV subscribers reached 1.5 million, with 34 thousand additions in the quarter. The average monthly fixed churn rate decreased to 1.2% in Q224, marking the lowest since Q4 2006, as a result of a rationalized fixed market and our content-rich IPTV service, TV+.

TURKCELL INTERNATIONAL

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

BeST revenues increased 22.3% year-on-year in local currency terms, mainly due to rise in data and outgoing voice revenues in Q224. BeST registered an EBITDA of BYN25.0 million in the second quarter, which led to an EBITDA margin increase to 47.9%. BeST’s revenues in TRY terms decreased 0.6% year-on-year in Q224.

BeST continued to offer LTE services to all six regions, encompassing 4.3 thousand sites in Q224. Enhanced LTE coverage has enabled BeST to expand its 4G subscriber base. Accordingly, 4G users reached 84% 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 4% year-on-year, reaching 19.8 GB in Q224.

(2) Kuzey Kıbrıs Turkcell, in which we hold a 100% stake, has operated in Northern Cyprus since 1999.

Kuzey Kıbrıs Turkcell revenues rose 12.5% year-on-year in Q224 on the back of the rise in ARPU. The EBITDA of Kuzey Kıbrıs Turkcell decreased by 1.4%, yielding a 33.0% EBITDA margin. Personnel expenses adversely impacted the margin.

TECHFIN

Paycell’s revenue rose by 15.8% year-on-year for the second quarter of 2024. Pay Later and POS solutions supported topline growth thanks to an increase in transaction volume and commission fees. Accordingly, Paycell’s EBITDA increased 14.3% year-on-year, leading to an EBITDA margin of 48.4% in Q224.

Pay Later service transaction volume (non-group) increased by 34% year-on-year to TRY2.6 billion in Q224. 3-month active Pay Later users were up 10% to 6.1 million in Q224. Additionally, the Paycell card transaction volume rose 85% year-on-year to TRY6.3 billion. The overall transaction volume for POS solutions also increased to TRY8.7 billion, with a yearly increase of 86%. Meanwhile, the total transaction volume across all services increased 48% to TRY22.0 billion year-on-year in Q224.

(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 classified from Financell to "Other" in the Techfin segment as of the first quarter of 2023.

Financell’s revenues rose by 33.9% in Q224. The main factor contributing to this growth was the higher average interest rate on the portfolio as compared to the same period of last year. EBITDA decreased 59.8%, pointing to an EBITDA margin of 14.1%. The increase in funding costs has led to a decline in the EBITDA margin on a yearly basis.

Financell’s loan portfolio was at TRY6.3 billion in Q224, with loans provided to approximately 31 thousand corporate customers. Financell’s cost of risk was at 2.2% at the end of the quarter. In this quarter, Financell began offering loans at varying rates based on customers’ individual risk profiles. It has continued to provide innovative solutions, including green loans for solar projects, car loans, and shopping loans for individual and corporate customers.

Turkcell Group Subscribers

Turkcell Group registered subscribers amounted to approximately 56.6 million as of June 30, 2024. This figure is calculated by taking the number of subscribers of Turkcell Türkiye, and of each of our subsidiaries. It includes the total number of mobile, fiber, ADSL, cable, and IPTV subscribers of Turkcell Türkiye and the mobile subscribers of lifecell*, BeST, and Kuzey Kıbrıs Turkcell.

(1) Subscribers to more than one service are counted separately for each service. Including mobile, fixed broadband, IPTV, and wholesale (MVNO&FVNO) subscribers

OVERVIEW OF THE MACROECONOMIC ENVIRONMENT

The foreign exchange rates used in our financial reporting, along with certain macroeconomic indicators, are set out below.

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 and intangible assets (affecting relative depreciation expense and amortization 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 IFRS. The following table provides a reconciliation of Adjusted EBITDA, as calculated using financial data prepared in accordance with IFRS to net profit, which we believe is the most directly comparable financial measure calculated and presented in accordance with IFRS.

RECONCILIATION OF ARPU: ARPU is an operational measurement tool and the methodology for calculating performance measures such as ARPU varies substantially among operators and is not standardized across the telecommunications industry, and reported performance measures thus vary from those that may result from 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 for Q2 2023 and Q2 2024.

(1) Revenue from fixed corporate and wholesale business; digital business sales; tower business, and other non-subscriber-based revenues

(2) Revenues from Turkcell Türkiye included in ARPU calculation comprise telecommunication services revenue, equipment revenue and revenues which are not attributed to ARPU calculation.

*Including call center revenues
