Turkcell İletişim Hizmetleri A.Ş. submitted a Form 6-K as a foreign private issuer, mainly to furnish its Turkcell 2025 Integrated Annual Report to the U.S. Securities and Exchange Commission. The attached report is a translation of the Turkish annual report.
The annual report was prepared under the Capital Markets Board of Türkiye rules, using Turkish Accounting Standards and Turkish Financial Reporting Standards, and audited under Turkish auditing standards. The filing is administrative in nature and does not itself present detailed financial results.
Turkcell İletişim Hizmetleri A.Ş. completed a new local-currency bond financing, issuing TRY 500,000,000 in debt to qualified investors in Türkiye. The bond carries an annual simple interest rate of 40.25% and matures on June 24, 2026, with a single coupon payment on that date.
The issuance was carried out under Turkcell’s TRY 10,000,000,000 domestic debt limit approved by the Capital Markets Board and was sold via private placement, with transfer to investor accounts on March 12, 2026. The instrument is rated AAA (tr) on a long-term national scale by JCR Avrasya and is designated as investment grade.
Turkcell reported full-year 2025 results prepared under IFRS and hyperinflation accounting (IAS 29), showing solid operational growth in a challenging Turkish macro environment.
Group revenue rose 10.7% year-on-year to TRY 241.5 billion, driven mainly by Turkcell Türkiye, which contributed 91% of revenue. EBITDA increased 13.8% to TRY 104.0 billion, lifting the EBITDA margin to 43.1% from 41.9%, as disciplined cost management lowered cost of revenue to 45.2% of sales.
Profit from continuing operations grew 22.6% to TRY 17.8 billion, but net income declined 42.8% to TRY 17.6 billion due to the absence of a one-off gain from the 2024 sale of Ukrainian assets. The company maintained very low leverage, with net debt of TRY 14.9 billion and net debt/EBITDA of 0.14x.
Turkcell expanded its mobile base to 39.1 million and achieved 2.4 million postpaid net additions, raising the postpaid share to 81%. ARPU increased, with blended mobile ARPU excluding M2M up 10.6% and residential fiber ARPU up 15.4%, supported by price adjustments, higher-speed packages and more contracted customers.
Techfin activities added diversification: Paycell revenue grew 41.0% to TRY 7.25 billion, while Financell modestly increased revenue and returned to profit. The group invested heavily, with total capex of TRY 90.0 billion, focusing on 5G spectrum, fiber, data centers and solar power, and completed a USD 1 billion dual-tranche Eurobond to support these priorities. For 2026, management targets revenue growth of 5%–7%, a 40%–42% EBITDA margin and capex at 25% of revenue.
Turkcell İletişim Hizmetleri A.Ş. reported that its Board of Directors authorized its wholly-owned subsidiary Turkcell Finansman A.Ş. to potentially issue commodity trading-based lease certificates (sukuk) in Türkiye. The program allows issuances of up to TRY 3 billion, with maturities of up to 12 months, in the domestic market.
The sukuk may be issued in one or more tranches, without a public offering, as private placements and/or sold to institutional investors through an asset leasing company based in Türkiye. These issuances are explicitly stated as being subject to approval by the Capital Markets Board.
Turkcell İletişim Hizmetleri A.Ş. reported that it has fully redeemed its short-term financing bond with ISIN code TRFTCEL22617. The bond had a nominal amount of TRY 750,000,000, a maturity of 96 days and carried a fixed annual simple interest rate of 39.25%.
On February 24, 2026, Turkcell paid the single coupon of TRY 77,424,750.00 and repaid the full principal of TRY 750,000,000.00, with both payments marked as completed. The bond was issued via private placement to qualified investors in Türkiye and was traded on the stock exchange.
The filing also notes that rating agency JCR Avrasya Derecelendirme A.Ş. assigned Turkcell a long-term national rating of AAA (Trk) as of May 29, 2025, classified as investment grade.
Turkcell İletişim Hizmetleri A.Ş. reports that the Turkish Capital Markets Board has approved an amendment to its Articles of Association. The change updates the company’s purpose clause to include services under an “Authorisation Certificate for Limited Use Rights with regard to IMT‑2020 Services,” alongside its existing mobile and IMT‑2000/UMTS authorizations.
Turkcell İletişim Hizmetleri A.Ş. has set the date for releasing its full-year 2025 financial results. The company plans to publicly announce results for the period from January 1, 2025 to December 31, 2025 on March 5, 2026 after Borsa Istanbul trading hours.
Turkcell İletişim Hizmetleri A.Ş. reported that its Board of Directors has authorized its wholly owned subsidiary, Turkcell Ödeme ve Elektronik Para Hizmetleri A.Ş., to issue management agreement-based lease certificates (sukuk) in Türkiye. The subsidiary may issue up to TRY 3 billion of these instruments in the domestic market, with maturities of up to 12 months, in one or more tranches. The sukuk will be placed without a public offering, through private placements and/or sales to qualified investors via an asset leasing company based in Türkiye. These issuances remain subject to approval by the Capital Markets Board.
Turkcell İletişim Hizmetleri A.Ş. reports that its merger through acquisition of its wholly owned subsidiary Artel Bilişim Servisleri A.Ş. has been completed and registered with the Trade Registry. This transaction follows a board decision dated 22 August 2025 and uses financial statements as of 30 June 2025 as the merger basis.
The merger is structured as a facilitated procedure under Turkish regulations and involves no change in Turkcell’s paid-in capital. Group A shares with paid-in capital of TRY 330,000,000 and Group B shares with paid-in capital of TRY 1,870,000,000 together total a paid-in capital of TRY 2,200,000,000. The tables state that the amount of capital to be increased or decreased due to the acquisition is TRY 0, so the target capital remains TRY 2,200,000,000.
The Capital Markets Board application regarding the merger was approved, with approval dated 25 November 2025, and the registry date of the merger is 31 December 2025. Overall, this is an internal reorganization step that consolidates a non‑listed, wholly owned subsidiary into the parent without altering the company’s registered capital structure.
