A fiber speed test in a home is over in a few seconds. In Turk Telekom's books, the same speed moves much more heavily: 155.2 billion TL in total investment spending in 1Q26, 120.5 billion TL of license and concession debt payable to BTK, a contract extended to February 28, 2050, and, if not renewed, the transfer without charge of the equipment required for the system. That is why reading TTKOM merely as a "telecom operator" misses the center of the stock. The company sells subscribers; the stock is the financing price of the national network built over those subscribers.
At first glance the table is attractive: 64.9 billion TL of revenue, 27.4 billion TL of EBITDA, a 42.3% EBITDA margin, and 10.5 billion TL of net profit. Yet in the same quarter, operating cash flow is negative 11.7 billion TL. Cash and cash equivalents fall from 71.5 billion TL at the beginning of the period to 28.3 billion TL at the end. There is profit, but the sentence spoken by the cash box is harsher.
The company's economic machine has two parts. The first remains strong: fixed-line contributed 39.1 billion TL to consolidated revenue in 1Q26; mobile contributed 25.8 billion TL. As of March 31, 2026, there are 17.3 million fixed access lines, 15.4 million broadband subscribers, 32.2 million mobile subscribers, and 2.9 million TV subscribers. Fiber is moving toward the home and the building: FTTH/B subscribers have risen from 5.6 million to 7.1 million. This is a real migration from the old fixed voice network to the new data network.
The second part is more ruthless: this migration is not free. The annual report shows normalized investment spending of 17.0 billion TL; when solar, concession extension, and mobile license fees are included, total investment spending reaches 155.2 billion TL. The financial note says most of this total comes from an 88.0 billion TL concession right and a 50.1 billion TL 5G license capitalization. This is not one quarter's operating investment; it is the rewriting of an infrastructure right on the balance sheet.
| Metric | Q1 2025 | Q1 2026 | YoY change |
|---|---|---|---|
| Mobile subscribers | 27.9m | 32.2m | 15.6% |
| Blended mobile ARPU | TRY 305.3 | TRY 265.0 | (13.2)% |
| Fiber to the home/building | 5.6m | 7.1m | 27.2% |
| Fixed broadband ARPU | TRY 387.6 | TRY 456.2 | 17.7% |
The subscriber picture is also double-faced. Mobile subscribers rise 15.6%, mobile postpaid lines grow 22.7%; against that, blended mobile ARPU falls 13.2%. Excluding M2M, the decline is more limited, but the message is clear: growth is not the same thing as pricing power. The 17.7% increase in fixed broadband ARPU is a cleaner signal. Turk Telekom's good side is here: while the old voice line erodes, the fiber and broadband bill can still be carried upward.
The main stain on earnings quality is TMS 29. The company reported 10.5 billion TL in net profit; the income statement includes a 14.0 billion TL net monetary position gain. This is the kind of accounting wind that indebted companies see under high-inflation accounting. It would be wrong to ignore the wind completely, because these are the rules of the financial statements; but buying the stock only on an annualized net profit multiple is also too easy. In the same quarter, FX and derivative expenses are 8.5 billion TL, and the net foreign currency liability position including hedges is 111.6 billion TL. The books record a gain from inflation while FX debt enters through another door.
That is why management's language matters. For 2026, it targets revenue growth excluding IFRIC 12 of 8-9%, an EBITDA margin of 41-42%, and capex/sales revenues of 33-34%. In 1Q26, the margin is above target; revenue growth excluding IFRIC 12 is weaker at 5.9%; the normalized capex/sales ratio is roughly 26.3%. The operation looks disciplined. But the decision not to distribute dividends from 2025 profit is the real management sentence: debt repayment plans, 5G license payments, investments, and the concession extension fee took priority for liquidity. In the near term, this is not a "pay me the profit" stock; it is a "finance the network, then talk about cash" stock.
Ownership magnifies this tension. The Turkey Wealth Fund is the largest shareholder with 61.68%; the Treasury holds 25% and the Group C Golden Share. The Golden Share requires an affirmative vote on amendments to the articles of association, share transfers affecting control, and share ledger transactions on grounds of national interest. This does not have to be a bad thing; telecom infrastructure is already a strategic asset. But for the minority shareholder, the decision set is not simple. Capital allocation sometimes speaks with the state, licenses, regulation, and network continuity before it speaks with the market's dividend expectation.
Valuation becomes interesting here. According to market data dated May 18, 2026, the share price is 61.55 TL and market capitalization is 215.4 billion TL. If you deduct cash only from financial debt, net debt is roughly 111.5 billion TL and enterprise value becomes 327.0 billion TL; annualizing 1Q26 EBITDA gives an EV/EBITDA of about 3.0x. That is cheap, but incomplete. When the license and concession liabilities payable to BTK are also treated as debt-like burdens, adjusted enterprise value rises to 447.5 billion TL and the multiple climbs to 4.1x. The cheapness still does not disappear; it merely becomes more honest.
| Item | Amount | Reading |
|---|---|---|
| Market value | TRY 215.4bn | 18 May 2026 price: TRY 61.55 |
| Net financial debt | TRY 111.5bn | Interest-bearing liabilities less cash |
| BTK license/concession payables | TRY 120.5bn | Discounted obligation carried in other payables |
| Adjusted enterprise value | TRY 447.5bn | Market value + net debt + BTK burden |
| Annualized Q1 2026 EBITDA | TRY 109.8bn | TRY 27.4bn x 4 |
| Current adjusted EV/EBITDA | 4.1x | The cheapness survives including BTK obligations |
| 4.5x sensitivity value | TRY 74.8/share | About 21% upside |
| 5.0x sensitivity value | TRY 90.5/share | About 47% upside |
That is why this report's verdict is Cheap. Cheap, because the market prices the company at roughly 4.1x annualized EBITDA including BTK burdens; the EBITDA margin is above 42%; broadband and fiber still carry price; even 4.5x adjusted EV/EBITDA points to a value of roughly 74.8 TL per share. In a 5.0x scenario, value rises to roughly 90.5 TL. This does not require a wild growth story; it requires only that operations do not break and that the large license/concession burden is digested according to plan.
But cheapness is not a gift box. The path to capital loss is very concrete: operating cash does not return, mobile ARPU dilution becomes permanent, FX/derivative expenses eat the EBITDA improvement, BTK and 5G payments are refinanced with new expensive debt, and the dividend horizon is postponed again and again. Worse, the commitment to invest at least 300 million dollars every year and 17 billion dollars in total through 2050 waits off the balance sheet; the financial report states that no provision has been booked for these commitments. This is the kind of long term shareholders dislike but infrastructure economics loves.
The fair antithesis is this: annualizing one quarter of EBITDA may be too generous. If revenue growth remains below management's target, if the decline in mobile ARPU suffocates subscriber growth, and if operating cash remains negative in the second quarter, then the 4.1x multiple is not an opportunity but the discount the market correctly placed. The investor carrying the stock should not look at an easy slogan like "state control is bad," but at a narrower question: can the company preserve EBITDA and pricing power while paying these burdens?
My kill condition is simple. If revenue growth excluding IFRIC 12 drifts away from the target band, if the EBITDA margin falls below 40%, if operating cash remains meaningfully negative in the second quarter, or if the BTK/5G payment schedule damages the cost of new borrowing, this thesis moves down. If the opposite happens, meaning cash flow returns and the margin is preserved while investment spending normalizes, what the market prices today as fear will gradually look like only the long-term cost of infrastructure.
TTKOM is not for the investor who wants a quick dividend or a simple story on the balance sheet. This stock is for the investor who can wait for the long-term cash conversion of a highly indebted but profitable network operating under a state concession. To own it is not to believe in fiber growth alone, but to believe that while the deed to the fiber sits with the state, the cash left beneath that deed may one day work for the shareholder too.
