Turkcell reported solid first-quarter 2026 results while stepping up 5G investment. Consolidated revenue reached TRY 68.4 billion, up 8.9% year-on-year, driven mainly by Turkcell Türkiye and strong Digital Business Services and Paycell contributions. EBITDA rose 3.2% to TRY 28.3 billion, with a 41.4% margin, while net income increased 14.9% to TRY 4.6 billion, supported by substantial monetary gain and better results from equity-accounted investees.
The company accelerated its network strategy, launching 5G services in Türkiye and acquiring a 5G license, which, together with a USD 1.2 billion license cost and related payments, lifted capital expenditures to TRY 76.6 billion. It also secured a USD 1 billion Murabaha syndicated loan, increasing consolidated debt to TRY 206.3 billion and raising net debt to TRY 48.8 billion, though the net debt-to-EBITDA ratio remains low at 0.42x.
Operationally, Turkcell Türkiye’s mobile base grew to 44.5 million subscribers, with 655–661 thousand net mobile additions and postpaid reaching 81% of the base. Fiber and Superbox 5G continued to expand, and Techfin results were mixed: Paycell revenue rose 15.3% while Financell’s revenue declined but profitability improved sharply.

Turkcell İletişim Hizmetleri A.Ş. submitted a notice that it included a disclosure required by the Iran Threat Reduction and Syria Human Rights Act of 2012 (Section 219) and Section 13(r) of the Exchange Act in its Annual Report on Form 20-F for the year ended December 31, 2025.

Turkcell İletişim Hizmetleri A.Ş. files its 2025 Form 20-F, presenting IFRS financials restated under IAS 29 because Türkiye is classified as a hyperinflationary economy. All periods are expressed in the purchasing power of the Turkish Lira as of December 31, 2025.
The report highlights extensive macroeconomic and FX risks tied to Türkiye, including high but declining inflation, Turkish Lira depreciation, and sensitivity to geopolitical conflicts and global monetary tightening. Turkcell notes significant FX exposure because most debt and capex are in USD, EUR and CNY while revenues are largely in TRY.
Turkcell also details industry and regulatory risks such as license renewal and 5G rollout obligations, spectrum and coverage requirements, strict pricing caps, data-protection rules, sector-specific taxes and potential fines. Competitive pressures, MVNO access on 5G, technology shifts (5G, eSIM, AI) and expansion into adjacent areas like data centers, fintech and renewable energy are framed as strategic but execution‑sensitive.
