Fitch Ratings has revised Turk Telekomunikasyon A.S.'s (TT) Outlook on its Long-Term Foreign-Currency (LTFC) Issuer Default Rating (IDR) to Positive from Stable and affirmed all ratings as detailed below.

The rating action follows the revision of the Outlook on Turkey's Long-Term IDRs to Positive from Stable on 23 January 2026 (see 'Fitch Revises Turkiye's Outlook to Positive; Affirms at 'BB-'). TT's high exposure to the Turkish economy means its LTFC IDR is influenced by the Turkish Country Ceiling, which remains at 'BB-'. The revision of the Outlook reflects the likely correlation of future rating actions with changes to the sovereign rating, if the Country Ceiling moves in line with the sovereign IDR.

The ratings affirmation also follows the update of Fitch's Corporate Rating Criteria and the Sector Navigators - Addendum to the Corporate Rating Criteria on 9 January 2026.

Corporate Rating Tool Inputs and Scores

Fitch scored TT as follows, using our Corporate Rating Tool (CRT) to produce the Standalone Credit Profile (SCP):

The business and financial profile factors (score, relative importance) are management ('bbb', lower), sector characteristics ('bbb', lower), market and competitive positioning ('bbb+', higher), diversification and asset quality ('bb+', moderate), company operational characteristics ('bb+', moderate), profitability ('bbb+', lower), financial structure ('bb', moderate), and financial flexibility ('bb', higher).

The quantitative financial subfactors are based on custom CRT financial period parameters: 20% weight for forecast FY25, 40% for forecast FY26 and 40% for forecast FY27.

The governance assessment of 'good' results in no adjustment.

The operating environment assessment of 'bb-' results in an adjustment of -1 notch.

The SCP is 'bb'.

To derive the IDR:

Application of Fitch's Parent Subsidiary Linkage (PSL) Rating Criteria results in a consolidated profile +1 approach.

Application of Fitch's Government Related Entities Rating Criteria results in a standalone approach.

Country Ceiling considerations apply and result in an adjustment of -1 notch.

RATING SENSITIVITIES

Factors that Could, Individually or Collectively, Lead to Negative Rating Action/Downgrade

EBITDA net leverage above 3.2x on a sustained basis

Material deterioration in pre-dividend free cash flow margin or in the regulatory or operating environments

Negative action on Turkiye's Country Ceiling or Long-Term Local Currency IDR, which could lead to a corresponding action on TT's Long-Term Foreign- or Local-Currency IDRs

Increased FX mismatch between TT's net debt and cash flows especially if combined with excessive reliance on short-term funding, without adequate liquidity over the next 12-18 months

Removal of covenants in debt documentation may lead to a change in PSL assessment, which could result in the IDRs being capped by the sovereign IDRs

Factors that Could, Individually or Collectively, Lead to Positive Rating Action/Upgrade

Positive rating action on Turkiye would lead to a corresponding action on TT, provided that TT's SCP is at the same level as, or higher than, the sovereign rating, and the links between the government and TT remain unchanged

Decreased currency mismatch between TT's net debt and cash flows or more effective hedging may lead to a positive action on the SCP, but not necessarily the IDR

Liquidity and Debt Structure

See the RAC referenced above.

ESG Considerations

The highest level of ESG credit relevance is a score of '3', unless otherwise disclosed in this section. A score of '3' means ESG issues are credit-neutral or have only a minimal credit impact on the entity, either due to their nature or the way in which they are being managed by the entity. Fitch's ESG Relevance Scores are not inputs in the rating process; they are an observation on the relevance and materiality of ESG factors in the rating decision.
