SEGMENT INFORMATION

In accordance with our integrated communication and technology services strategy, we have reported our telecom related businesses in Turkey and outside of Turkey under Turkcell Turkey and Turkcell International reportable segments, respectively. All other businesses were reported under the Other segment until Q121.

Starting from Q121, our financial services businesses; Turkcell Finansman A.Ş., Turkcell Ödeme ve Elektronik Para Hizmetleri A.Ş., Turkcell Sigorta Aracılık Hizmetleri A.Ş., and Paycell LLC, will be reported under the new Techfin segment. In previous releases, these businesses were included under the Other segment. We made this change since these entities have similar business models, and to some extent have operations integrated with each other. Moreover, these businesses are subject to legislation and regulations, which differ from those applied to other entities reported under the Other segment.

Furthermore, operations of Turkcell Satış ve Dijital İş Servisleri Hizmetleri A.Ş. (“Turkcell Satış”), which are reported under Turkcell Turkey are separated as “Digital Business Services” and other Turkcell Satış operations: Integrated corporate business solutions, city hospitals, equipment and corporate terminal activities will continue to be reported under Turkcell Turkey as “Digital Business Services”, while other Turkcell Satış operations, which include retail channel operations, smart devices management and consumer electronics sales through digital channels, will be reported in the Other segment. We have made this change since other Turkcell Satış operations, which are reported under the Other segment, are now less connected with the integrated business model of Turkcell Turkey. Accordingly, these operations mainly comprise the procurement and sale of consumer electronics not limited to integrated telco products. They target non-Turkcell customers as well. Moreover, these operations also have different level of operating profitability compared to businesses reported under Turkcell Turkey.

There have been no changes to Turkcell International segment.

Starting from Q121, our reporting segments will be as follows:

“Turkcell Turkey” comprises “Turkcell İletişim Hizmetleri A.Ş.”, “Superonline İletişim Hizmetleri A.Ş.”, the group call center operations of “Global Bilgi Pazarlama Danışmanlık ve Çağrı Servisi Hizmetleri A.Ş.”, the abovementioned digital business services operations of “Turkcell Satış”, “Turktell Bilişim Servisleri A.Ş.”, “Turkcell Teknoloji Araştırma ve Geliştirme A.Ş.”, “Kule Hizmet ve İşletmecilik A.Ş.”, “Rehberlik Hizmetleri A.Ş.”, “Turkcell Gayrimenkul Hizmetleri A.Ş.”, “Lifecell Dijital Servisler ve Çözümler A.Ş.”, “Lifecell Bulut Çözümleri A.Ş.”, “Lifecell TV Yayın ve İçerik Hizmetleri A.Ş.”, “Lifecell Müzik Yayın ve İletim A.Ş.”, “BiP İletişim Teknolojileri ve Dijital Servisler A.Ş.” and “Turkcell Dijital İş Servisleri A.Ş.”.

COMMENTS BY CEO, MURAT ERKAN

We began the year strongly with our customer-driven approach

Having made a strong start, we have concluded this quarter with strong operational and financial results matching up with our targets. In this period in which we managed our business successfully, in spite of the challenging conditions of the COVID-19 pandemic, we continued our strong growth and achieved successful results. This was made possible by offering enriched value offers to our customers with our “Customer First” focus, and reflective of our diversified business model with strategic focus areas.

Our consolidated revenues rose 17.5% year-on-year, reaching TRY7.8 billion. Consolidated EBITDA¹ grew by 17.7% to TRY3.3 billion, resulting in an EBITDA margin of 42.2%. 26.6% growth in Turkcell International business contributed to the topline growth. Net income increased by 26.6% to TRY1.1 billion. These results, in line with our targets, have reinforced our confidence in reaching our guidance for the year 2021, despite the challenging environment due to the pandemic.

The highest subscriber additions of the past 3 years

Thanks to our value offers meeting changing customer needs and our innovative campaigns facilitating the lives of our customers, we recorded 410 thousand postpaid subscriber and 190 thousand prepaid subscriber net additions in this quarter. Including the fixed broadband and IPTV services, the total 705 thousand net subscriber addition marks our highest level of the past 3 years. Our strong and fast network, convenient digital sales channels and brand loyalty have been instrumental in customers opting for Turkcell. Our postpaid customer base reached 22.4 million, reflecting 66% of the total mobile base on a 3 point rise year-over-year. Mobile blended ARPU (except for M2M) has reached TRY49.9 on an annual 8.7% rise on the back of a larger postpaid subscription base, rising data and digital service use and upsell efforts, despite the negative effect of the pandemic. We enhanced our customer loyalty by combining our customer-driven approach and analytical competences; accordingly, the average monthly churn rate of 1.8% was the lowest level of the past 3 years.

The strong demand for fixed broadband has continued in this quarter, too, under the prevailing mobility restrictions within the scope of measures against the pandemic, and more widespread remote working. We gained a net 50 thousand fiber subscribers with our high-speed and unlimited fiber internet offers designed to meet the need for speed in homes where a large number of devices are connected at the same time. Accordingly, our fixed broadband customer base reached 2.5 million.

Interest in our digital services is rising daily

We continue pioneering the digital transformation of Turkey with the instant messaging, TV and music platforms, personal cloud services, search engine and e-mail services developed by Turkcell engineers. Enjoying increasing recognition, BiP, our instant messaging application, saw 32 million new downloads in this quarter. With its total downloads reaching 77 million, BiP has been the most downloaded local application in Turkey. With no imposition or discriminating among its users in terms of data privacy, BiP has reached 40 million three-month active users, approximately one third of which are outside of Turkey. TV+, our web-based digital TV platform, has been another outstanding service this quarter. Both IPTV and the OTT TV+ service users have accelerated in this quarter thanks to enriched content, as well as its accessibility through smart televisions. With the addition of net 49 thousand IPTV customers, we now offer IPTV services to 61 out of every 100 households among our residential fiber customers.

We launched GAMEPLUS, our new gaming platform on which we have been focusing recently, in March in collaboration with NVIDIA GeForce NOW, a cloud-based gaming service. Thanks to the cloud-based gaming technology eliminating the need for particular hardware to play games, users can access over 950 games. We believe that the strong interest in this platform, which has reached 10.4 thousand premium users within just 15 days will continue in the coming periods.

Overall, the stand-alone revenue of our digital services business reached TRY367 million with an increase of 28% year-over-year in this quarter, mainly on the back of these developments. We aim at more diversified monetization with the launch of the B2B models of fizy business, lifebox business and BiP Meet services over the coming months.

Turkcell Digital Business Services continues pioneering the digital transformation of companies

The total revenues of Digital Business Services through which we offer a wide range of new generation technologies to our corporate customers, from access to cyber security, from cloud technologies to data centers, and from managed services to the internet of things, reached TRY452 million on an annual increase of 27% in this quarter. We have supported corporates on their digitalization journey by signing over 700 new contracts. As of the end of the first quarter, we have put into practice 1,589 system integration and managed services projects to date; from these projects we have a contract value (backlog) of TRY1.1 billion to be realized after the first quarter of 2021. We have continued to strengthen our ecosystem by increasing the number of our global partnerships. In the first quarter we launched the SOAR (Security Orchestration Automation and Response) Service allowing for instantaneous actions to be taken over security components against incidents of cyber-attack, a Forensics service enabling corporations to learn about the trajectory of events taking place, including the weaknesses being exploited and likely remedial methods to be employed following probable cyber-attacks, as well as the Turkcell Digital Facility, our first IoT Platform service. Along with these, we continued enriching our portfolio by relaunching Kopilot Filom and a brand-new user experience on turkcellbulut.com.tr.

Growth of the Techfin sector’s rising star, Paycell, gains speed

Paycell, our innovative payment services platform in the field of techfin, marked a successful quarter with its rising users and growing mobile payment volume. As the number of three-month active Paycell users reached 5.3 million, mobile payment volume reached TRY351 million, doubling on an annual basis. During the same period, the Paycell Card transaction volume quadrupled. Overall, Paycell revenues grew by 53% on an annual basis in this quarter; non-group revenue increased 81%. In the forthcoming period, we aim at the widespread use of our Android POS service, an increased number of member merchants, and reaching more customers with our new services.

We have set our sustainability targets

We, as Turkcell Group, have prioritized the use of renewable sources towards our goal of maximizing the efficient use of natural resources, reflective of our business model which is sensitive to the environment and based on shaping technology according to the needs of society. As we have also shared at the ‘GSMA Mobile Net Zero’ event on April 20, we aim to meet 100% of our electricity consumption through renewable resources by 2030.

Also this quarter, as a pioneer in mobile working in Turkey, we have put into practice our “Flexible Working Model” designed together with our employees. Accordingly, our employees, reflecting their preferences and planning, can work remotely or at our offices if need be, for an indefinite period without any limitation on location. With this model, we aim at enhancing the comfort and productivity of our employees, while at the same time offering the best working experience.

Dividend of TRY 2.6 billion approved at the Ordinary General Assembly

As part of our disclosure about the change in our shareholding structure, we had stated that the number of seats on the Board of Directors was increased to nine. At the Turkcell Ordinary General Assembly meeting held on April 15, these appointments were realized and the number of members set forth in our articles of association has been completed. At the same meeting, the distribution of the dividend of TRY2.6 billion, corresponding to 61% of the net distributable period profit, in three equal installments was approved. We are pleased to have distributed the first installment on the same day as this earnings disclosure.

We will continue to serve our country and people with sustained investments in the upcoming period

In firm hopes that the COVID-19 pandemic may finally be behind us in the near future, I believe wholeheartedly that we will achieve new successes, while serving our country and people in the quarters ahead.

I extend my thanks to all our colleagues for their contribution that has enabled our strong start to the year, and to our Board of Directors for their confidence in us and their invaluable support. I also express our gratitude to our customers and business partners, ever with us on our journey to success.

Historical periods were restated to reflect this change.

Revenue of the Group grew by 17.5% year-on-year in Q121. This resulted mainly from Turkcell Turkey’s revenue growth supported by a larger subscriber base, price adjustments, higher data consumption and digital services usage. Turkcell International’s strong revenue growth and equipment sales backed by digital channels also assisted the Group revenue rise.

Turkcell Turkey revenues, comprising 76% of Group revenues, rose 13.3% year-on-year to TRY5,979 million (TRY5,276 million).

- Consumer segment revenues grew 11.3% driven mainly by a larger subscriber base, increased data consumption and digital services usage.

- Corporate segment revenues rose 19.6% backed by robust performance on digital business services, which grew 27.3%.

- Standalone digital services revenues registered as part of consumer and corporate segments grew 27.5% year-on-year in Q121 supported by the increase in the number of paid users.

- Wholesale revenues grew 22.0% to TRY340 million (TRY279 million), mainly with data capacity upgrades of customers and the positive impact of currency movements, despite lower roaming revenues impacted by limited mobility.

Turkcell International revenues, comprising 9% of Group revenues, increased 26.6% to TRY708 million (TRY560) million. This was mainly driven by strong revenue growth in Ukrainian operations and the positive impact of currency movements.

Total techfin segment revenues, comprising 3% of Group revenues, were at TRY223 million (TRY220 million). The decline in the finance company’s revenues, which was due mainly to loan portfolio contraction, was more than offset by the increase in Paycell revenues. Please refer to the Techfin section for details.

Other subsidiaries' revenues, at 12% of Group revenues, which mainly includes non-group call center and energy business revenues, and consumer electronics sales revenues rose 52.2% to TRY917 million (TRY603 million). This was driven mainly by the increase in equipment revenues supported by digital channels.

Cost of revenue (excluding depreciation and amortization) rose to 50.0% (48.0%) as a percentage of revenues in Q121. This was due mainly to the increase in cost of goods sold (2.9pp), despite the decline in treasury share expense (0.6pp) and other cost items (0.3pp) as a percentage of revenues.

Administrative Expenses declined to 2.5% (2.8%) as a percentage of revenues in Q121, driven mainly by lower office overhead costs and travel expenses.

Selling and Marketing Expenses declined to 4.6% (5.2%) as a percentage of revenues in Q121. This was driven mainly by the decline in selling expenses (0.6pp) as a percentage of revenues.

Net impairment losses on financial and contract assets declined to 0.6% (1.7%) as a percentage of revenues in Q121 mainly with the better collection performance.

EBITDA¹ rose by 17.7% year-on-year in Q121 leading to an EBITDA margin of 42.2% (42.2%), driven mainly by strong revenue growth.

- Turkcell International EBITDA grew 37.9% year-on-year to TRY345 million (TRY250 million) with an EBITDA margin of 48.6% (44.6%). This performance was led by strong revenue growth and disciplined cost controls.

- Techfin segment EBITDA was at TRY138 million (TRY137 million) with an EBITDA margin of 62.0% (62.1%).

- The EBITDA of other subsidiaries stood at TRY93 million (TRY35 million).

Depreciation and amortization expenses increased 20.7% year-on-year in Q121.

Net finance expense declined to TRY207 million (TRY221 million) in Q121. This was driven mainly by higher interest income, despite a higher net FX loss after hedging, and a larger interest expense on financial assets and liabilities.

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

Income tax expense increased to TRY344 million (TRY244 million) due mainly to a higher deferred tax expense incurred in Q121.

Please see Appendix A for details.

Net income of the Group rose 26.6% to TRY1,105 million (TRY873 million) in Q121, mainly due to robust operational profitability and higher interest income on time deposits, despite a higher net FX loss after hedging.

Total cash & debt: Consolidated cash as of March 31, 2021 increased to TRY13,467 million from TRY11,861 million as of December 31, 2020, driven by cash flow generation and the positive impact of currency movements. Excluding FX swap transactions, 78% of our cash is in US$, 8% in EUR, 13% in TRY and the remaining in other currencies.

Consolidated debt as of March 31, 2021 increased to TRY24,896 million from TRY21,586 million as of December 31, 2020 mainly due to the impact of currency movements and new borrowings. Please note that TRY2,248 million of our consolidated debt is comprised of lease obligations.

Consolidated debt breakdown excluding lease obligations:

(1) Superbox subscribers are included in mobile subscribers.

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

(3) In Q117, our churn policy was revised to extend from 9 months to 12 months (the period at the end of which we disconnect prepaid subscribers who have not topped up above TRY10). Additionally, under our revised policy, prepaid customers who last topped up before March is disconnected at the latest by year-end. As a regulatory requirement, we started to disconnect prepaid lines in accordance with the new ICTA regulation, which requires deactivation of prepaid lines which lack residency documents by the 6^th month of subscription starting from 2019. Furthermore, as required by the ICTA, the line of a deceased customer should either be transferred to a successor/another user or terminated. Lines, which are not transferred or terminated, are to be disconnected at the end of seven months.

(4) We historically recorded all TV-related revenue under Turkcell Superonline and presented the related ARPU under fixed residential ARPU. As previously announced, our TV business has become a separate standalone subsidiary. In order to reflect this change in our organization, we decided to shift mobile OTT TV ARPU from fixed residential ARPU into mobile ARPU starting from Q320. We note that mobile TV revenues are generated by mobile subscribers. IPTV revenues will continue to be recorded under Turkcell Superonline and included under residential fixed ARPU. Moreover, starting from Q121, as a consequence of the change in reportable segments, commission revenues resulting from devices and accessories sales have been excluded from mobile ARPU of Turkcell Turkey since these commissions are now reported under the Other segment. In order to maintain comparability, we provide ARPU data for the last three years, revised to reflect this change on our investor relations website in the financial and operational data spreadsheet.

We started the year registering a strong subscriber net addition performance. Accordingly, the Turkcell Turkey subscriber base expanded by 705 thousand quarterly net additions, reaching 37.4 million. This robust performance was driven mainly by our offerings with rich value propositions, customer-oriented campaigns and retention focus. This also confirms our commitment to achieving 1 million subscriber net additions for the full year.

On the mobile front, our subscriber base expanded by 599 thousand quarterly net additions, reaching 34.0 million in total. This was mainly driven by 410 thousand quarterly net additions to the postpaid subscriber base, which reached 65.8% (63.2%) of total mobile subscribers. Meanwhile, we registered 190 thousand quarterly net prepaid subscriber additions.

On the fixed front, our subscriber base continued to grow, reaching 2.5 million subscribers on 56 thousand total quarterly net additions. Fiber subscribers exceeded 1.7 million on 50 thousand quarterly net additions. Superbox, our fixed-wireless access offering alternative to fiber, reached 615 thousand subscribers on 23 thousand quarterly net additions in Q121. Our cable subscribers were at 65 thousand by the end of the quarter. Meanwhile, our IPTV customers rose to 921 thousand on 49 thousand quarterly net additions.

The average monthly mobile churn rate declined to 1.8% in Q121, which was the lowest churn rate since Q118. Our customer experience approach supported by analytical capabilities resulted in a better customer retention performance. The average monthly fixed churn rate declined to 1.6% mainly driven by proactive retention actions.

Our mobile ARPU (excluding M2M) rose 8.7% year-on-year in Q121 on the back of price adjustments and a higher postpaid subscriber share, as well as increased data consumption and digital services usage, despite lower roaming revenues.

Our residential fiber ARPU growth was 8.8% year-on-year in Q121. This was driven mainly by price adjustments, upsell efforts and the acquisition of higher revenue generating subscribers.

Average monthly mobile data usage per user rose 28.6% year-on-year to 12.6 GB with the increasing number and data consumption of 4.5G users. Accordingly, the average mobile data usage of 4.5G users reached 14.4 GB in Q121 on 24.1% year-on-year rise. The increasing number of Superbox subscribers also had a positive impact on data consumption.

Total smartphone⁵ penetration on our network reached 84% in Q121 on a 5.9pp year-on-year increase. 91% of those smartphones are 4.5G compatible smartphones. The number of 4.5G subscriptions reached 32.4 million, while only 70% of these subscriptions have 4.5G compatible smartphones.

(5) Smartphone penetration was positively impacted by approximately 700 thousand smartphone net additions in Q121 that resulted from an algorithm improvement to detect devices which were not previously classified as smartphones.

TURKCELL INTERNATIONAL

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

lifecell (Ukraine) had another quarter with strong revenue growth performance. Accordingly, revenues rose 20.2% year-on-year in local currency terms, driven mainly by subscriber base growth, price adjustments and higher mobile data revenues. This was despite lower roaming revenues in Q121 due to the pandemic, which have yet to be restored. lifecell also registered robust EBITDA growth of 34.9%, which resulted in a 6.2pp EBITDA margin improvement to 56.7%. This was mainly the result of strong revenue growth, lower operational expenditures as a percentage of revenues led by savings in the pandemic environment and disciplined cost controls. The decline in MTR rates also supported lifecell’s solid EBITDA performance. Moreover, lifecell continued to report positive net income in Q121 on the back of strong operational performance.

lifecell revenues in TRY terms rose 31.7% year-on-year in Q121, which reflected the solid operational performance and positive impact of currency movements. lifecell’s EBITDA in TRY terms grew by 47.8% leading to an EBITDA margin of 56.7%.

(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.

lifecell’s three-month active subscriber base grew by 6.7% year-on-year to 8.0 million. This was driven mainly by lifecell’s regional offers, tariffs with rich content and customer retention focus. lifecell’s 3-month active ARPU rose 13.2% year-on-year to UAH78.7, driven mainly by price adjustments and increased data consumption.

lifecell continued to increase the penetration of its 4.5G users within its customer base in Q121. Accordingly, the 3-month active 4.5G subscribers grew 40% year-on-year reaching 66% of total data users as at the end of Q121. The increase in 4.5G users continued to support data consumption. Average data consumption per user rose 31% year-on-year in Q121 on the back of 4.5G users, the data usage of which rose 22% year-on-year to 13GB per month. Meanwhile, lifecell continued its leadership of the Ukrainian market in smartphone penetration, which had reached 82% as of the end of Q121.

lifecell continued its focus on increasing the penetration of its digital services within its customer base in Q121.

(1) BeST, in which we hold an 80% stake, has operated in Belarus since July 2008.

BeST revenues grew by 16.9% year-on-year in local currency terms. This was driven mainly by growth in voice, data, messaging and handset sales revenues, despite lower roaming revenues due to the pandemic. BeST’s EBITDA grew 9.5% year-on-year resulting in an EBITDA margin of 24.2%. BeST’s revenues in TRY terms grew by 22.8% in Q121 year-on-year, while its EBITDA margin was at 24.2%.

BeST continued to expand its 4G coverage in Belarus in Q121. Accordingly, it leads the market in terms of 4G geographical coverage. Furthermore, BeST started to provide LTE800 service over beCloud’s network in 2 regions, which enabled higher coverage and positively impacted customer satisfaction. All these efforts supported the increase of 4G services penetration as reflected by the number of 4G users, which reached 65% of its 3-month active subscriber base. This led to higher average monthly data consumption of subscribers, which reached 12.7 GB on 35% year-on-year growth.

BeST continued its efforts to promote its digital services in Q121, as digital services usage leads to higher loyalty and increased ARPU generation. Accordingly, 33% of 3-month active subscribers use at least one digital service.

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

Kuzey Kıbrıs Turkcell revenues grew 13.6% year-on-year in Q121, driven by higher data and handset sales revenues. The EBITDA of Kuzey Kıbrıs Turkcell rose 20.7% year-on-year leading to an EBITDA margin of 39.6%. This was driven by the revenue growth as well as savings achieved in the pandemic environment.

TECHFIN

Paycell registered a remarkable performance in Q121 achieving 52.6% year-on year revenue growth. This performance was positively impacted by the increasing demand for e-commerce transactions through cashless payment methods. Paycell was able monetize this demand with its mobile payment solutions; particularly direct carrier billing and e-money. Paycell’s EBITDA rose 46.4% year-on-year leading to an EBITDA margin of 54.4%. With a focus on expanding its business, Paycell concentrated its efforts on growing non-group driven revenues. Accordingly, non-group revenues rose 81.4% year-on-year this quarter. The strong operational performance resulted in a robust net income rise of 41.1% to TRY40.2 million.

On the operational front, Paycell’s 3-month active users numbered 5.3 million. The increase in active users was driven mainly by increased digital content consumption, an expanding merchant channel and functionality of the Paycell application. Paycell serves 13 thousand contracted merchants as at the end of the quarter. The total transaction volume of TRY2.4 billion for the quarter was a result of the increase in active users and their increased consumption. The DCB transactions volume (non-group) rose 106% year-on-year, while Paycell card transaction volume was up by 291%. Meanwhile, Paycell also continues its efforts to increase the penetration of its android POS, which will facilitate expanding the merchant channel, as well as support payment facilitator revenues.

Financell revenues continued to contract in Q121 due mainly to the lower loan portfolio compared to the same period of the previous year and lower average interest rate on loan portfolio. Meanwhile, the decline in Financell’s EBITDA was slower compared to revenues which resulted in 4.5pp rise in EBITDA margin. This was driven mainly by the customer portfolio improvement with better credit scoring, successful collection performance and sale of doubtful receivables that led to a decline in bad debt expenses. Net income increased 51.3% year-on-year to TRY95.0 million, driven mainly by lower FX loss after hedging.

Financell’s loan portfolio declined from TRY2.1 billion as of Q120 to TRY1.9 billion as of Q121. This was due mainly to the installment limitation on consumer loans for telecom devices. Moreover, sales volume was affected by the negative impacts of COVID-19 measures. Compared to the previous quarter, Financell had a more stable loan portfolio. In the meantime, Financell’s cost of risk declined to 1.0% from 2.3% in Q420, due mainly to a successful collection performance, customer portfolio improvement, as well as the sale of doubtful receivables. Please also note that 81% of the loans granted by Financell over the last year is covered by an insurance product.

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 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 translation gain/(loss), finance income, finance expense, share of profit of equity accounted investees, gain on sale of investments, minority interest and other income/(expense).

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 as issued by the IASB, to net profit, which we believe is the most directly comparable financial measure calculated and presented in accordance with IFRS as issued by the IASB.
