Is TEO a Buy or a Sell? The Bull and Bear Case (2026)

That depends on which case you find more convincing, and both are on this page. The bull case rests on Integrating Movistar Argentina while giving part of it away, with revenue (1h 2026) at ~P$5.08 trillion, roughly ~$3.4B at ~1,500 pesos per dollar, +16.0% vs 1H25 in constant pesos. The bear case rests on the single largest risk is that the reported numbers are an artifact of Argentine macro rather than operations: IAS 29 restatement, the inflation index chosen and the peso-versus-dollar path can move net income by hundreds of billions of pesos in either direction without a single subscriber changing behavior, and the 2025 full-year loss versus the 2026 first-half profit is the clearest illustration. Analysts covering it are spread from $9.20 to $19.00, which is itself a signal that this is genuinely contested. If you believe the thesis, the real questions become sizing and overlap rather than timing. Walnut is not an investment adviser and this is not a recommendation.

Nobody can answer that for you, and the honest version of the question is narrower: has anything changed in the reason you bought it? The bear case on this page is the place to check. The single largest risk is that the reported numbers are an artifact of Argentine macro rather than operations: IAS 29 restatement, the inflation index chosen and the peso-versus-dollar path can move net income by hundreds of billions of pesos in either direction without a single subscriber changing behavior, and the 2025 full-year loss versus the 2026 first-half profit is the clearest illustration. If that risk is what you were worried about and it is now playing out, that is a real signal. If the price simply fell while the thesis held, that is a different situation entirely. The most pessimistic published target is $9.20, -33.5% from the $13.83 price, which is one analyst's downside case rather than a floor. Walnut is not an investment adviser.

Integrating Movistar Argentina while giving part of it away. The acquired unit contributed a full six months to first-half 2026 versus four months in the comparable 2025 period, which is most of the reported 16.0% consolidated revenue increase. The most optimistic analyst target on TEO is $19.00, +37.4% from the $13.83 price. That figure is only reachable if this thesis works close to its best case.

The single largest risk is that the reported numbers are an artifact of Argentine macro rather than operations: IAS 29 restatement, the inflation index chosen and the peso-versus-dollar path can move net income by hundreds of billions of pesos in either direction without a single subscriber changing behavior, and the 2025 full-year loss versus the 2026 first-half profit is the clearest illustration. Dollar-denominated borrowings against peso revenue mean a renewed devaluation would reverse the foreign exchange gains that produced the recent profit, and Argentine capital controls have historically restricted transferring funds abroad, which affects both debt service and any distribution reaching ADR holders. Execution risk on the antitrust remedy is live and unresolved: transferring 6 million mobile customers, spectrum and 211,400 broadband subscribers requires finding a buyer and effectively funding a new national competitor, and the terms, timing and price of that transfer are not yet known. Competitively, Claro remains the other national mobile operator, Starlink is named in the company's own filings as having reached a meaningful Argentine subscriber base in under a year, and low-earth-orbit satellite broadband lowers the barrier to entry in exactly the fixed markets where Telecom's pricing has already lagged inflation. Finally, this is a controlled company with a shareholders' agreement between Cablevision Holding and Fintech Telecom, ADR holders vote only through the depositary, cash distributions have been small and irregular (some past distributions were made in Argentine sovereign bonds rather than cash), and Argentine consumer-protection courts have repeatedly ordered customer reimbursements. The most pessimistic published target is $9.20, -33.5% from the current price, which is roughly what the stock is worth if these risks bite rather than the drivers.

Argentina's largest integrated telecom operator, running Personal mobile, Flow pay television and fixed broadband, with reported results dominated by inflation accounting.

Decide that in advance, because it is far harder to think clearly once a position is moving against you. The concrete tripwires here: the driver behind the bull case (Integrating Movistar Argentina while giving part of it away) stalling in the reported numbers rather than in the narrative, the risk above (the single largest risk is that the reported numbers are an artifact of Argentine macro rather than operations: IAS 29 restatement, the inflation index chosen and the peso-versus-dollar path can move net income by hundreds of billions of pesos in either direction without a single subscriber changing behavior, and the 2025 full-year loss versus the 2026 first-half profit is the clearest illustration) turning from a possibility into a reported fact, or the position growing large enough that a bad outcome would matter to your whole portfolio regardless of who is right.

It is Argentina's largest integrated telecom operator, providing mobile service under the Personal brand, fixed broadband, cable television under Flow, fixed voice and data, and fintech through Personal Pay. As of June 30, 2026 it served roughly 38.9 million mobile lines in Argentina across the legacy Telecom base and the acquired Movistar unit, about 5.9 million broadband accesses and about 3.8 million pay TV subscribers. Smaller operations run in Paraguay through Nucleo, plus Uruguay, Chile and US wholesale.

Each TEO American Depositary Share represents rights to five Class B shares of Telecom Argentina under a deposit agreement with JP Morgan dated May 7, 2021. The underlying Class B shares trade in Buenos Aires on BYMA under the symbol TECO2. Total capital stock is 2,153,688,011 shares split across Class A, B, C and D, all with one vote each, and only the Class B shares underlie the ADRs.

Argentina is treated as a hyperinflationary economy, so the company reports under IAS 29, which restates every figure into the purchasing power of the measuring unit at the balance sheet date and re-expresses prior periods using the national CPI. For the first half of 2026 that index was 33.5% over twelve months, meaning a business growing 30% in nominal pesos actually shrank in real terms. Reading TEO's growth rates without checking whether the figures are nominal or constant currency produces conclusions that are simply wrong.
