<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">As a result of the scheduling of the convening of Turkcell's annual general meeting and the impact that this has had on Turkcell's
board and audit committee, the Company is unable to file its Annual Report on Form 20-F without unreasonable effort or expense.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The convening
of the annual general shareholders' meeting was impacted by the following: (i) the Public Oversight Accounting and Auditing Standards
Authority of T&uuml;rkiye announced on November 23, 2023 that, starting from the financial reporting for accounting periods ending as
of December 31, 2023, companies applying Turkish Financial Reporting Standards (&ldquo;TFRS&rdquo;) must adjust their financial tables
as per Turkish Accounting Standard principle 29 (TAS 29) - &ldquo;Financial Reporting in Hyperinflationary Economies;&rdquo; (ii) the
Turkish Capital Markets Board (the &ldquo;CMB&rdquo;) issued a decision indicating that companies subject to CMB regulations must apply
inflation accounting as per TAS 29 for their financial reports for accounting periods ending as of December 31, 2023; and (iii) on December
28, 2023, the CMB further decided that the filing deadline for 2023 consolidated annual financial reports where TAS 29 will be applied
for the first time was extended by ten weeks.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">Due to the above factors, the Company issued its 2023 consolidated annual financial reports
on March 20th, 2024 in accordance with TFRS. As issuing the annual consolidated financials is a prerequisite for convening the annual
general assembly meeting, the shortest practicable timeline was taken into consideration in scheduling the meeting of shareholders for
May 2, 2024.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">However, the terms of office of the current members of the Company's board of directors, including the audit committee members,
reached their scheduled expiration dates on April 15, 2024. The election of Turkcell's new board of directors is slated to occur at the
May 2nd shareholders' meeting.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The Company expects to file the report on Form 20-F as soon as practicable following the annual shareholders'
meeting and the election of our board of directors and not later than the fifteenth calendar day following its prescribed due date.</P>
