WHY WE ARE HERE 6 Turkcell has excellent assets, an enviable market position and significant value creation potentialHowever, beneath topline and subscriber growth, Turkcell is shockingly operationally inefficient and is underperforming its peers. It has destroyed value with poor capital allocationThe governance regime is inadequate, Turkcell’s Board is weak and insufficiently accountable to shareholders and disclosure is below international standardsOperating, strategic and governance failings have resulted in poor share price performance and a low valuation – investor confidence has been lostOur efforts to engage constructively with Turkcell’s Board have been rebuffedL1 has a clear, executable plan to realize Turkcell’s potential (“Strategic Plan”). Execution must begin with experienced, transparent and accountable governanceIMTIS is seeking shareholders support at the upcoming Generally Assembly to put the governance foundation in place to address Turkcell’s failings. We need you to vote for:Electing 4 unaffiliated and highly qualified director candidates for 1 yearImproving director accountability with individual director voting (i.e. not slate voting)Bringing disclosure up to internationally accepted standardsApproving 2021 dividend payout of 75% of FY2021 net income Through IMTIS’ beneficial ownership of 19.8% of Turkcell’s shares. LetterOne is Turkcell’s 2nd largest economic investor(1) having been invested for over 16 years. Despite an enviable market position and asset base, Turkcell’s strategic and operating performance is weak. Its governance regime is poor. Valuation is low and investor confidence decreasing.CHANGE IS REQUIRED AND IT MUST START BY IMPROVING GOVERNANCE

THE PROBLEMS AT TURKCELL 7 2 3 Turkcell Failings Turkcell share price has underperformed Türk Telekom, Turkish stock index and index of EM telcos by 11% / 33% / 63% since June 2020(1)With 3.4x 2022 EV/EBITDA multiple, Turkcell has one of the lowest valuations in EM telco2 international brokers recently downgraded Turkcell to “Sell” for the first time in 5 years and 3 brokers reduced Turkcell to “Hold” Investors have lost Confidence in Turkcell Major Operational Inefficiencies: One of the lowest OpFCF margins compared to peersWeak Commercial Results: Loss of market share, high churn, lowest growth in the market with the highest cost and Capex structureLack of Execution of SOTP Value Unlock Strategy: Significant value in digital and infrastructure assets. Value unlock strategy announced 2Q – 2019 – no progress since, despite a robust market environmentDestruction of Value in International Subsidiaries and TOGG: +$2.2bn invested in Ukraine and Belarus, unjustified TOGG investmentLow Dividend: Dividend yield and payout are significantly below EM telco peers despite low leverageNo Alignment between Management and Shareholders’ Interest: Management compensation unrelated to long-term TSR. No stock ownership among managementExceptionally Weak Corporate Governance: Weak Board. Widely criticized director election process in 2021. ISS and Glass Lewis expressed numerous concerns and recommended voting against the Board at the 2021 General Assembly Since shareholder restructuring transaction announcement of 18-Jun-20

VOTING RESULTS AT THE 2021 GENERAL ASSEMBLY INDICATE LACK OF TRUST IN THE CURRENT BOARD 8 “[Turkcell] should have a robust nomination and election process to ensure an effective board that is accountable to shareholders. Shareholders should be able to participate in frequent elections of all board members, preferably on an annual basis.”- Norges Bank Investment Management(3) Proxy Insight. Data as of 21 January 2022. Ownership data from FactSet. Vote results from Proxy Insight. All data as of 21 January 2022. Note that “Institutions” exclude TWF, LetterOne and Turkcell ADRs. SunAmerica represents the lowest-ranked institution for which voting data is available. Although there are 193 institutions for which ownership data is available on FactSet, only 93 of those publicly disclose their voting decisions.Norges Bank Investment Management proxy voting disclosure, available here: https://www.nbim.no/en/the-fund/responsible-investment/our-voting-records/meeting/?m=1517920 The recommendations of ISS and Glass Lewis and the pattern of shareholder voting at the 2021 General Assembly reflect major dissatisfaction with the way Turkcell is being managed All but one of Turkcell’s 93 shareholders that have publicly disclosed their voting results(1) voted against the proposal to ratify the appointment of directors at the 2021 General AssemblyIn our experience, it is unusual to have such unanimity among the shareholder base, which exemplifies investors’ widespread lack of trust in this Board Both leading proxy advisory firms, ISS and Glass Lewis, recommended against the director appointment ratification proposal Rank Institution(2) Vote at 2021 General Assembly 2 The Vanguard Group, Inc.

EFFORTS TO ENGAGE WITH TURKCELL’S BOARD HAVE BEEN REBUFFED 11 L1 and IMTIS have sought constructive dialogue with Turkcell. The Board’s decision not to engage with its second largest stakeholder demonstrates its lack of experience, skills and alignment with shareholder interests Date Attempt to Engage Turkcell’s Response 14 – 15 October L1 met with Turkcell Chairman and management team to present findings of operational and strategic failings. SC 13D amended Turkcell does not respond 28 October L1 and IMTIS send a private letter to Turkcell Chairman outlining their concerns and proposed solutions Turkcell responds with a letter on 12 November, failing to respond to L1’s and IMTIS’ concerns. States that Turkcell “is taking the utmost care to implement the most efficient and optimal governance tools and procedures.” Recommends that, regarding operational matters, “you can always refer your questions and comments to the management” 15 November L1 and IMTIS publicly disclose their letter via an amended SC 13D and in KAP Turkcell does not respond 16 November L1 and IMTIS send a private letter urging the Board to engage constructively, noting that the issues raised are the responsibility of the Board Turkcell does not respond 18 November L1 and IMTIS send another letter to the Board noting that their concerns go beyond mere compliance; we request a meeting with the Chairman and Committees’ chairs Turkcell does not respond 30 November L1 and IMTIS send another letter indicating an intent to reserve the right to take action to ensure shareholder interests are protected Turkcell responds with a letter on 8 December, again failing to respond to L1’s concerns. Reiterates view that Turkcell is implementing “the most efficient and optimal internal governance tools,” etc. Once again encourages L1 and IMTIS to speak with management instead 4 January IMTIS sends a director nomination letter to the Board. IMTIS requests response from the Board by 26-Jan-22. SC 13D amended and disclosed in KAP. Turkcell filed a 6-K announcing its receipt of a letter dated 4 January from IMTIS that requested the dismissal of four board members and the election of candidates to replace these directors at the next General Assembly. Turkcell does not provide any feedback on director nomination as per IMTIS request by 26-Jan-22

TURKCELL’S POOR INVESTMENT TRACK RECORD OUTSIDE OF TURKEY Subsidiary Description Ukraine (100% owned by Turkcell) Turkcell spent +$1bn in equity contributions to Lifecell Ukraine over the last 17 years (~$165m in L5Y) with no dollar of return(1)Despite significant investments, Lifecell remains a distant #3 player with only 14% revenue market share vs. ~25% share in the allocated spectrum(2)Lifecell generated $6m of OpFC in FY20 or 2.3% of Lifecell revenue. This dilutes Group OpFCF. EqFCF FY20 was -$3m(3) Belarus (80% owned by Turkcell) Turkcell spent $1.2bn in equity contributions to Lifecell Belarus over the last 13 years with no dollar of return(1) In addition, there is a $100m contingent obligation to Belarusian Government in case business becomes profitable Despite significant investments, Lifecell remains a distant #3 player with sub 10% revenue market shareTurkcell loses more than $10m per annum in Belarus with little prospect of becoming profitable TOGG (23% owned by Turkcell) Established in 2018, TOGG is a Turkish start-up electric vehicle manufacturer founded by Anadolu Group, BMC Otomotiv, Kök Ulaşım, Vestel, Turkcell (each with 19% shareholding initially) and Turkish Union of Chambers and Commodity Exchanges of Turkey (“TOBB”) with 5% shareholding. All the initial major backers of the project have significant automotive or industrial expertise other than TurkcellParties initially committed €500m equity funding to the project with €95m share of Turkcell. However, in 2021 Kök decided not to participate in the capital increase and as a result Turkcell share of the project increased to 23.0%Turkcell has so far invested ~€40m(1) and has further commitment of ~€65m Given TOGG’s total commitment is ~4% of Turkcell’s Market Cap and no contribution to Turkcell’s core business, we believe Turkcell’s Board should review the future of Turkcell’s stake in TOGG Note: OpFCF is Adj. EBITDA less Adj. Capex. Adj. EBITDA is Reported EBITDA post IFRS 16 and 15 minus capitalized CAC and total lease payments. Adj. Capex is Capex minus licenses, capitalized CAC and IFRS 16 lease right-of-use additions. EqFCF defined as OpFCF minus net financial interest paid, minus WC and taxes paid. Based on Turkcell’s historical 20-F reports. Based on financial reporting of Kyivstar, Vodafone Ukraine and Lifecell Ukraine. Based on Lifecell’s financial reports. 30 Management’s weak allocation of capital has added to shareholders’ dissatisfaction

LOW DIVIDEND PAYOUT SECTION 5:

TURKCELL DIVIDEND PAYOUT IS INADEQUATE 32 Turkcell’s dividend payout is significantly below EM telco peers despite low financial leverage.

LACK OF ALIGNMENT BETWEEN MANAGEMENT AND SHAREHOLDERS’ INTERESTS SECTION 6:

34 No real long-term alignment between management and shareholders Existing LTI Plan (based on external reporting) LTI Plan Flaws Small share of total compensation delivered via LTI vs. total compVery short-term focused plan with cash payments after 1-2 years Cash-settled LTI plan introduced in Jan-2016 for selected employees. Payment amount is subject to company performance measures (Shareholder Return > WACC and ranking of TSR vs BIST 30 and peer group) and linked to TKC share price performance. The bonus amount is distributed over a 3y payment planLTI plan constituted only 8.7% of total key management compensation including indemnities, salaries, bonuses and other benefits over 2017-2020 (plan criteria was met in 2017 and 2019 FYs)Turkcell Board members and senior officers only held 0.0028% of shares over the last 2 years (or ~$140k) and not significantly more in the prior years (0.0053% in 2018 or ~$500k – max in the L5Y) EXISTING LTI PLAN DOES NOT CREATE ALIGNMENT BETWEEN KEY EXECUTIVES AND SHAREHOLDERS No personal holding / requirements to build ownership of shares by key execsKey execs do not have exposure to both upside and downside like shareholders do The lack of equity incentives in the LTI plan is inappropriate for a company of Turkcell’s stature

As such, [Turkcell] should adhere to higher disclosure and corporate governance standards.”(1) 26 March 2021 “[Turkcell] provides no information regarding the names and biographical details of nominees, which prevents shareholders from objectively evaluating the performance of directors and their independence… We encourage the Company to provide significantly more information regarding these issues going forward…Under the Company’s articles of association, directors may be elected for a term of up to three years.
