For further details, please refer to the headings of the financial tables beginning on page 13.

• For analysis purposes, it is important to highlight that the comparative results (December 2024) reflect the year-over-year effect of inflation through December 2025, which reached 31.5%. Additionally, the consolidated results for FY25 include ten months of TMA's results, which were not present in the comparative period (FY24).
• During FY25, consolidated revenues reached P$8,328,814 million. Service revenues totaled P$7,902,043 million in FY25, with the following performance:
  • Telecom (excluding TMA)3: +4.2% vs. FY24 (vs. -6.4% in real terms in FY24 vs. FY23).
  • TMA: +3.8% vs. FY24. Telecom does not set TMA's commercial or pricing policies.
  • Consolidated: +54.7% vs. FY24, including ten months of TMA revenues not reflected in the comparative consolidated period (FY24).
• During FY25, the customer base in Argentina showed positive evolution:
  • Telecom (excluding TMA): Total mobile accesses decreased 7.8%, totaling 19.9 million. This reduction is largely explained by disconnections of prepaid lines with no recorded traffic, with no effect on mobile service revenues. In turn, the fixed segment recorded increases in the number of accesses: TV accesses totaled 3.3 million in the same period (+46 thousand or +1.4% vs. FY24), while fixed broadband accesses increased 3.2%, totaling 4.2 million accesses (+130 thousand vs. FY24).
  • TMA: Total mobile accesses (including M2M) totaled 19.1 million (+308 thousand or +1.6% vs. FY24). Fixed broadband reached 1.6 million accesses (+89 thousand or +5.8% vs. FY24). In turn, TV subscribers totaled 0.4 million in the same period (-33 thousand or -7.9% vs. FY24).

• During FY25, consolidated Operating Income Before Depreciation, Amortization and Impairment of Fixed Assets ("Operating Income before D, A & I") margin was 30.3% (+2.1 p.p. vs. FY24). Telecom (excluding TMA) margin improved, reaching 33.7% in FY25 (+5.5 p.p. vs. FY24) and 34.1% in 4Q25 (+7.9 p.p. vs. 4Q24). Operating income before D, A & I totaled P$2,525,535 million (+64.8% vs. FY24, including 10 months of TMA).
• During FY25, a consolidated net loss of P$145,304 million was recorded (vs. a net income of P$1,359,230 million in FY24). This was mainly due to a higher loss from exchange rate differences recorded in financial results, measured in real terms, as a result of lower inflation (31.5%) vs. a depreciation of the Argentine peso against the US dollar of 41.0% (vs. inflation of 117.8% and peso depreciation of 27.7% in FY24).
• Consolidated CAPEX (excluding right-of-use assets) totaled P$1,485,577 million (+98.3% vs. FY24) and represented 17.8% of consolidated revenues (increasing vs. FY24, when it reached 13.8% of revenues).
• Consolidated Net Financial Debt totaled P$4,650,085 million as of December 31, 2025, increasing in real terms (+40.2% in constant currency vs. December 31, 2024), mainly due to financing obtained for the acquisition of TMA. Relative leverage improved, as net financial debt increased at a lower rate than Operating Income before D, A & I.

Revenues from equipment sales

Consolidated revenues from equipment sales totaled P$426,771 million (+P$93,245 million or +28.0% vs. FY24).

The cost breakdown was as follows:

• Labor costs and severance payments totaled P$1,961,097 million in FY25 (+P$614,360 million or +45.6% vs. FY24). The increase was mainly due to the consolidation of TMA's results in FY25, whose contribution amounted to P$685,616 million.

• Interconnection and transmission costs, which also include roaming, correspondence services, and line and circuit rentals, amounted to P$243,797 million in FY25 (+P$87,879 million or +56.4% vs. FY24). The increase was mainly due to the consolidation of TMA's results in FY25, whose contribution amounted to P$206,096 million.

• Fees for services, maintenance and materials totaled P$1,064,393 million in FY25 (+P$340,273 million or +47.0% vs. FY24). The increase was mainly due to the consolidation of TMA's results in FY25, whose contribution amounted to P$360,546 million. Excluding the impact of TMA's consolidation, the decrease was mainly explained by higher efficiencies, with reductions in maintenance and materials costs and professional fees compared to FY24.

• Taxes, fees and regulatory charges totaled P$720,488 million (+P$292,136 million or +68.2% vs. FY24). FY25 taxes, fees and regulatory charges include P$259,255 million related to TMA.

• Commissions and advertising (agents, collection commissions and other commissions) totaled P$437,205 million in FY25 (+P$131,714 million or

  +43.1% vs. FY24). The increase was mainly due to the consolidation of TMA's

  results in FY25, whose contribution amounted to P$150,748 million.

• Cost of equipment sold totaled P$288,668 million in FY25 (+P$29,452 million or +11.4% vs. FY24). This variation was mainly due to the consolidation of TMA's results in FY25, whose contribution amounted to P$93,450 million.

  • Bad debt expenses in FY25 include P$57,820 million related to TMA. The charge for bad debt continued to show a favorable trend, representing 1.7% of total revenues as of December 31, 2025 (vs. 2.1% in FY24).

  • Other operating costs, which include charges for lawsuits and other contingencies, energy and other utilities, insurance, leases and internet capacity, among others, amounted to P$493,211 million (+P$228,993 million or +86.7% vs. FY24). TMA's contribution in FY25 amounted to P$178,842 million.

• Depreciation, amortization and impairment of fixed assets totaled P$2,075,488 million (+P$350,431 million or +20.3% vs. FY24). The charge for the period includes P$579,565 million related to the consolidation of TMA, as well as the impact of amortization of additions made after December 31, 2024, partially offset by the effect of assets that completed their useful lives after that same date.

Net Financial Results

Net financial results (including financial debt costs and other net financial results) showed a consolidated loss of P$638,041 million in FY25 (vs. a gain of P$2,105,237 million in FY24). The consolidation of TMA's results contributed a loss of P$35,461 million in FY25. This variation was mainly driven by:

The variation recorded in consolidated net financial results in FY25 was mainly explained by higher foreign exchange losses, measured in real terms, of P$2,794,475 million, resulting from inflation of 31.5% versus a 41.0% depreciation of the Argentine peso against the U.S. dollar (vs. inflation of 117.8% and a 27.7% depreciation of the Argentine peso against the U.S. dollar in FY24), higher loan interest expense of P$307,652 million, and higher losses from other items of P$24,320 million. These effects were partially offset by higher gains from changes in the fair value of financial assets of P$148,192 million, resulting from exposure to inflation of 31.5% on the market value of securities (compared to inflation of 117.8% in FY24), and higher gains from loan indexation of P$139,614 million, as the UVA adjustment was below inflation, generating positive results in real terms.

Income Tax

Telecom's income tax includes the following effects:

FY24 IAS 29 FY25 IAS 29

consisting of the merger by absorption of TSMA (as absorbed company) by Telecom Argentina (as absorbing company), effective as of January 1, 2026, from which date TSMA's operations shall be considered as carried out by Telecom Argentina.

Allocation of Results for the Fiscal Year

The fiscal year ended December 31, 2025, resulted in a Net Loss of P$123,939,460,761. The Board of Directors proposes that the Annual Shareholders' Meeting resolve, with respect to the Unappropriated Results as of December 31, 2025, which show a negative balance of P$123,939,460,761, as follows:

1. To absorb the amount of P$123,939,460,761 from the "Facultative Reserve to Maintain the Level of Investments in Capital Assets and the Company's Current Solvency Level"; and

2. That the results recorded during the fiscal year ended December 31, 2025, arising from the higher value assigned to the assets and liabilities identified and incorporated as of January 1, 2018 (effective date of the merger through which Telecom Argentina absorbed Cablevisión S.A.), which, net of tax effects, amount to a negative P$115,492,131,831, be reclassified against the Merger premium.
