TKC vs TT: How Turkcell and Trane Technologies Compare (2026)

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: TKC is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. TKC and TT share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined TKC and TT exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Turkcell is Turkey's largest mobile operator, with roughly ~46.7 million registered Group subscribers as of March 31, 2026, and it runs well beyond SIM cards. The Turkcell Turkey segment covers mobile plus Superonline fiber broadband and TV+, the Techfin segment holds Paycell (mobile payments and wallet) and Financell (consumer finance for handsets and devices), and a growing Digital Business Services and data center and cloud unit sells connectivity, hosting and integration to corporates. Turkcell International is much smaller after the company exited Ukraine: lifecell LLC, Global Bilgi and Ukrtower were sold to DVL Telecom, part of Xavier Niel's NJJ Holding, for ~$538.7 million, with the share transfer completed on September 9, 2024 and ~$524.3 million received. The Turkey Wealth Fund holds the controlling stake, which makes state ownership a permanent feature of the story rather than an event risk.

Trane Technologies is an Ireland-domiciled, US-listed maker of heating, ventilation, air conditioning (HVAC) and refrigeration systems, operating mainly through the Trane (commercial and residential HVAC) and Thermo King (transport refrigeration) brands. Roughly two-thirds of its business is commercial HVAC, where it sells energy-efficient chillers, rooftop units, controls, and a growing base of recurring service and aftermarket contracts. The company positions itself around sustainability and building decarbonization, and it has expanded aggressively into data-center cooling through acquisitions such as Stellar Energy.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• TKC drivers: 5G monetization after a paid-for spectrum position; Techfin and digital services growing off a small base.
• TT drivers: Data-center cooling demand; Commercial HVAC and backlog.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Currency is the dominant risk for a dollar holder: lira depreciation can convert lira-denominated growth into a flat or negative ADR return, and the last twelve months saw the ADR near ~$5.50 after a decline of roughly ~14%. For TT, the most cited risk is valuation: TT trades at a premium price-to-earnings multiple well above the broader industrial group and its own historical average, so any growth stumble could compress the multiple.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick TKC if you believe its drivers more; TT if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the TKC and TT guides.

TKC. Every operating figure is reported in Turkish lira and restated under IAS 29 inflation accounting, so the growth rates above are real rather than nominal and do not map cleanly onto a dollar-based valuation multiple. Guidance for 2026 is real revenue growth of ~5% to ~7%, an EBITDA margin of ~40% to ~42% and capex intensity near ~25% of revenue. Second quarter 2026 results are scheduled for release after the Borsa Istanbul close on August 13, 2026, which will be the first full quarter with commercial 5G in the numbers.

TT. Trane beat expectations in Q1 2026 and raised full-year guidance to roughly 7% organic revenue growth and adjusted EPS of about $14.75 to $14.95. A record backlog above $10 billion supports near-term visibility. The trailing P/E in the mid-30s sits well above the typical industrial multiple, reflecting the market's confidence in the growth story.

Headline figures (approximate, August 2026): TKC shows revenue (fy2025) ~TRY 241.5 billion, up ~10.7% in real terms, ebitda (fy2025) ~TRY 104.0 billion, margin ~43.1%, q1 2026 revenue and net income revenue ~TRY 68.4 billion (up ~8.9%), net income ~TRY 4.63 billion (up ~15%), q1 2026 adjusted ebitda margin ~41.4%, down ~2.3 percentage points year on year; TT shows market cap ~$105 billion, revenue (ttm) ~$21.3 billion, net income (ttm) ~$3.0 billion, q1 2026 revenue ~$4.97 billion (up ~6% YoY).

TKC and TT are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
