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.

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: In millions of $ FY25 FY24 Δ $ Exchange differences (327,336) 2,467,139 (2,794,475) Net interest (449,525) (141,873) (307,652) RECPAM 183,617 170,007 13,610 Fair value gains/(losses) on financial assets at fair value through profit or loss 88,469 (59,723) 148,192 Remeasurement in borrowings* 4,477 (135,137) 139,614 Others (137,743) (195,176) 57,433 Total (638,041) 2,105,237 (2,743,278) *Related to Notes issued in UVA 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: the current income tax, determined based on the tax legislation currently applicable to Telecom, the effect of applying the deferred tax method with respect to temporary differences determined by comparing our asset and liability valuations according to tax and financial accounting criteria, which includes the effect of the income tax inflation adjustment. Income tax showed a gain of P$46,432 million in FY25 (vs. a loss of P$538,237 million in FY24). Losses related to current income tax amounted to P$196,068 million in FY25 (vs. a loss of P$14,344 million in FY24), and the income tax charge related to the application of the deferred tax method in FY25 was a gain of P$242,500 million (vs. a loss of P$523,893 million in FY24). Income tax for FY25 includes a loss of P$39,163 million corresponding to the consolidation of TMA's results. Consolidated Net Financial Debt As of December 31, 2025, our net financial debt (cash, cash equivalents - net of Client Funds - plus financial investments and financial NDF* minus loans) amounted to P$4,650,085 million, representing an increase of P$1,333,436 million compared to Net Financial Debt as of December 31, 2024, adjusted for inflation. This increase was mainly driven by the financing obtained for the acquisition of TMA. In relative terms, the leverage profile improved, as net financial debt increased at a lower pace than Operating Income before D, A & I. * Contemplates rate s aps and NDF (non-delivery for ards) agreements. Investments in PP&E, intangible assets and rights of use assets As of December 31, 2025, consolidated CAPEX (including additions to PP&E and intangible assets) totaled P$1,485,577 million (+98.3% vs. FY24). CAPEX for Telecom (excluding TMA) totaled P$1,028,975 million (+37.4% vs. FY24). Including additions from right-of-use, investments amounted to P$1,681,289 million, including P$468,175 million related to TMA. The investments were focused on: Expansion of both fixed and mobile data services to improve transmission and access speed offered to customers, the deployment of 4G coverage and capacity, and continued expansion of 5G to support mobile internet growth and enhance service quality. Deployment and modernization of 4G mobile access sites to improve coverage and increase mobile network capacity. The 4G/LTE rollout reached 98% population coverage. According to the latest benchmark conducted by Ookla in December 2025, our mobile network customers with access to our 4G network experienced improved service quality, reaching average speeds of 78 Mbps. During 2025, we continued expanding our 5G network with the addition of 819 sites.
