Telecom Argentina S.A. announces consolidated results for the nine-month period (“9M25”) and third quarter of fiscal year 2025 (“3Q25”)2 Note: 9M25 figures include the effects of the adoption of inflationary accounting in accordance with IAS 29. Therefore, comments regarding 9M25 results and changes in 9M24 results mentioned in this press release correspond to “restated for inflation” or “constant” figures. Moreover, Table 3 shows information broken down by segment for the periods ended as of September 30 of 2025 and 2024, as analyzed by the Executive Committee and the CEO, who periodically receive the economic-financial information of Telecom and its subsidiaries (in historical values). The comments corresponding to the consolidated results for 9M25 include the results of Telefónica Móviles Argentina (“TMA”) for the seven-month period from March 1 to September 30, 2025, unless otherwise specified. For further details, please refer to the headings of the financial tables beginning on page 11.

| · | For analysis purposes, it is important to highlight that the comparative results (September 2024) reflect the year-over-year effect of inflation through September 2025, which reached 31.8%. Additionally, the consolidated results for 9M25 include seven months of contributions from TMA, which were not present in the comparative period 9M24.

| · | During 9M25, consolidated revenues reached P$5,622,561 million. Service revenues totaled P$5,327,305 million in 9M25, with the following performance:

| o | Telecom (excluding TMA)3: +4.1% vs. 9M24 (vs. -9.1% in real terms in 9M24 vs. 9M23).

| o | TMA: +5.3% vs. 9M24. Telecom does not determine TMA’s commercial or pricing policies.

| o | Consolidated: +50.7% vs. 9M24, including seven months of TMA revenues not present in the comparative consolidated period (9M24).

| · | During 9M25, the customer base in Argentina showed positive evolution:

| o | Telecom (excluding TMA): Total mobile accesses decreased by 5.0%, reaching 20.3 million. This decline was mainly due to disconnections of lines with no traffic, with no impact on mobile service revenues. Pay TV subscribers increased to 3.2 million (+44 thousand or +1.4% vs. 9M24). Fixed broadband accesses grew by 2.5%, totaling 4.1 million (+102 thousand vs. 9M24).

| o | TMA: Total mobile accesses (including M2M) reached 19.1 million (+305 thousand or +1.6% vs. 9M24). Fixed broadband totaled 1.6 million accesses (+92 thousand or +6.0% vs. 9M24). Pay TV subscribers reached 0.4 million (-29 thousand or -6.9% vs. 9M24).

| · | During 9M25, consolidated Operating Income Before Depreciation, Amortization and Impairment of Fixed Assets (“Operating Income before D, A & I”) margin was 30.5% (+1.7 p.p. vs. 9M24), and 31.4% in 3Q25. Telecom’s margin (excluding TMA) expanded to 33.0% in 9M25 (+4.2 p.p. vs. 9M24) and 34.0% in 3Q25 (+6.8 p.p. vs. 3Q24). Operating Income before D, A & I totaled P$1,716,387 million (+58.4% vs. 9M24, including seven months of TMA).

| · | During 9M25, a consolidated net loss of P$272,543 million was recorded (vs. a net income of P$1,254,213 million in 9M24). 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 (22.0%) vs. a depreciation of the Argentine peso against the US dollar of 33.7% (vs. inflation of 101.6% and peso depreciation of 20.0% in 9M24).

| · | Consolidated CAPEX (excluding rights of use) represented 15.1% of consolidated revenues in 9M25.

| · | Consolidated Net Financial Debt totaled P$4,433,988 million as of September 30, 2025, increasing in real terms (+44.3% in constant currency vs. December 31, 2024). This increase was mainly driven by the financing obtained for the acquisition of TMA.

Mobile internet revenues represented 98% of total mobile service revenues in both 9M25 and 9M24. Excluding the impact of TMA’s consolidation, Telecom (excluding TMA) registered a 10.6% increase in mobile service revenues, mainly driven by higher average monthly revenue per customer (“ARPU”).

Mobile Services in Argentina

As of September 30, 2025, Telecom’s mobile subscribers in Argentina (excluding TMA) totaled approximately 20.3 million (-1.1 million or -5.0% vs. 9M24). This decline was primarily due to disconnections of lines with no traffic, with no impact on mobile service revenues. As of September 30, 2025, 61% of customers were prepaid and 39% postpaid, compared to 62% prepaid and 38% postpaid as of September 30, 2024.

As of September 30, 2025, TMA’s mobile subscribers totaled approximately 19.1 million (+305 thousand or +1.6% vs. 9M24), including M2M accesses.

In 9M25, consolidated mobile service revenues in Argentina reached P$2,612,748 million (+P$1,227,724 million or +88.6% compared to 9M24). This increase was mainly driven by the consolidation of TMA’s results in 9M25, which totaled P$1,052,077 million. Excluding the impact of TMA’s consolidation, the growth was mainly attributable to a 13.6% real increase in ARPU.

The ARPU for Telecom (excluding TMA) was P$8,171.1 in 9M25 (+13.6% in real terms vs. 9M24). The effect of restatement to the current measurement unit as of September 30, 2025 included in ARPU amounted to P$605.7 and P$2,608.1 in 9M25 and 9M24, respectively. The average monthly churn stood at 2.1% in 9M25 (vs. 1.5% in 9M24).

During 9M25, mobile service revenues in Paraguay reached P$123,161 million, decreasing in real terms (-P$13,590 million vs. 9M24). This decrease is attributed to the widespread use of Wi-Fi networks, which impacted mobile data usage. The effect was partially offset by the real appreciation of the Guaraní.

The monthly churn for internet services stood at 1.2% and 1.6% as of September 30, 2025 and 2024, respectively.

The revenue increase was mainly driven by the consolidation of TMA’s results in 9M25, which totaled P$249,910 million. Excluding the impact of TMA’s consolidation, Telecom (excluding TMA) registered a 3.1% increase, primarily due to higher ARPU and subscriber growth.

TV subscribers for TMA totaled 0.4 million (-29 thousand or -6.9% vs. 9M24).

The positive variation in revenues in Argentina is mainly due to the consolidation of TMA’s results in 9M25, which amounted to P$63,729 million. Excluding the impact of TMA’s consolidation, the increase of 4.1% for Telecom (excluding TMA) was mainly driven by a 3.2% increase in ARPU and a 1.4% increase in the subscriber base compared to 9M24.

Telecom’s subscriber base in Argentina (excluding TMA) totaled 3.2 million accesses as of September 30, 2025, with an increase of 1.4% compared to 9M24, driven by Flow Full and Flow Flex products, the latter being fully digital (no decoder or installation required). Of this customer base, 1.7 million are subscribed to Flow Flex.

Fixed Telephony and Data Services

Consolidated revenues from fixed voice and data services reached P$676,563 million in 9M25 (+P$205,312 million or +43.6% compared to 9M24).

The variation in Argentina is mainly due to the consolidation of TMA’s results in 9M25, which amounted to P$282,029 million. Fixed voice and data revenues for Telecom (excluding TMA) decreased by 16.3%, mainly because the company has not been able to increase its prices in line with inflation, considering accumulated inflation over the last twelve months of 31.8%, and despite a 2.4% increase in the fixed customer base.

Telecom’s fixed voice customer base (excluding TMA) reached 2.8 million in 9M25, of which 2.2 million correspond to customers with IP lines. TMA’s telephony customer base reached 2.1 million, of which 1.5 million are customers with IP lines.

The main variation was driven by the increase in fintech services in Argentina, primarily due to the growth in usage of the Personal Pay digital wallet and the rise in the number of users, which reached 4.4 million in 9M25 vs. 3.3 million in 9M24.

Revenues from equipment sales

Consolidated equipment sales revenues totaled P$295,256 million (+P$71,224 million or +31.8% vs. 9M24). This variation was mainly driven by the consolidation of TMA’s results in 9M25, which amounted to P$114,447 million, while equipment sales for Telecom (excluding TMA) declined by 19.3% in real terms.

Consolidated Operating Costs

Consolidated Operating Costs including Depreciation, Amortization and Impairment of Fixed Assets amounted to P$5,270,240 million in 9M25 (+P$1,371,930 million or +35.2% vs. 9M24).

Operating costs for 9M25 include P$1,320,584 million corresponding to the consolidation of TMA. During 9M25, Telecom’s operating costs (excluding TMA) decreased by 3.3% in real terms.

The cost breakdown was as follows:

| · | Labor costs and severance payments totaled P$1,358,615 million in 9M25 (+P$443,530 million or +48.5% vs. 9M24). The increase is mainly due to the consolidation of TMA’s results in 9M25, whose contribution amounts to P$465,035 million. Telecom’s headcount totaled 18,977 employees as of September 30, 2025.

| · | Interconnection and transmission costs, which also include roaming, correspondent services, and line and circuit rentals, amounted to P$200,813 million in 9M25 (+P$88,431 million or +78.7% vs. 9M24). The increase is mainly due to the consolidation of TMA’s results in 9M25, whose contribution amounts to P$135,344 million. Excluding the impact of TMA’s consolidation, the decrease is mainly due to optimization in the use of links and sites and lower traffic levels.

TELECOM ARGENTINA | 6

| · | Fees for services, maintenance and materials: P$714,553 million in 9M25 (+P$207,981 million or +41.1% vs. 9M24). The increase is mainly due to the consolidation of TMA’s results in 9M25, whose contribution amounts to P$226,140 million. Excluding the impact of TMA’s consolidation, the decrease is explained mainly by greater efficiencies, which reduced maintenance and material costs and service fees compared to 9M24.

| · | Taxes, fees, and regulatory charges: P$485,015 million (+P$191,361 million or +65.2% vs. 9M24). Operating costs for taxes, fees and regulatory charges in 9M25 include P$167,904 million corresponding to TMA.

| · | Commissions and advertising (agents, collection commissions and other commissions): Charges totaled P$297,533 million in 9M25 (+P$92,755 million or +45.3% vs. 9M24). The increase is mainly due to the consolidation of TMA’s results in 9M25, whose contribution amounts to P$100,215 million.

| · | Costs of equipment sold totaled P$224,740 million in 9M25 (+P$51,120 million or +29.4% vs. 9M24). This variation is mainly due to the consolidation of TMA’s results in 9M25, whose contribution amounts to P$89,655 million.

| · | Programming and content costs: P$266,780 million (+P$53,788 million or +25.3% vs. 9M24). Programming and content costs for 9M25 include P$34,252 million corresponding to TMA.

| · | Bad debt expenses in 9M25 include P$38,926 million corresponding to TMA. The charge for bad debt continued to show a favorable trend: it represented 1.7% of total revenues as of September 30, 2025 (vs. 2.1% in 9M24).

| · | Other operating costs, which include litigation and contingency charges, energy and other utilities, insurance, rentals, and internet capacity, among others, amounted to P$260,826 million (+P$82,513 million or +46.3% vs. 9M24). TMA’s contribution for 9M25 totaled P$63,113 million.

| · | Depreciation, amortization, and impairment of fixed assets: totaled P$1,364,066 million (+P$140,487 million or +11.5% vs. 9M24). The charge for the period includes P$345,469 million corresponding to the consolidation of TMA and reflects the impact of amortizations from additions after September 30, 2024, partially offset by the effect of assets that reached the end of their useful life after that date.

Net Financial Results

Net financial results (including financial debt costs and other net financial results) showed a consolidated loss of P$685,200 million in 9M25 (vs. a gain of P$1,961,278 million in 9M24).

*Related to Notes issued in UVA

TELECOM ARGENTINA | 7

The variation in consolidated net financial results in 9M25 was mainly explained by a higher loss from foreign exchange differences, measured in real terms, of P$2,624,058 million. This was driven by inflation of 22.0% versus a 33.7% depreciation of the Argentine Peso against the U.S. dollar (vs. inflation of 101.6% and a 20.0% depreciation of the Argentine Peso against the U.S. dollar in 9M24). Additionally, there were higher financial debt interest expenses of P$144,750 million due to increased borrowing, partially offset by higher gains from loan adjustments of P$117,159 million, resulting from the maturity of UVA-denominated notes, which reduced the outstanding principal balance and, consequently, the associated financial charges.

Income Tax

Telecom’s income tax includes the following effects:

| i) | the current income tax, determined based on the current tax legislation applicable to Telecom,

| ii) | the effect of applying the deferred tax method with respect to temporary differences determined by comparing our asset and liability valuation according to tax and financial accounting criteria which includes the effect of the income tax inflation adjustment.

Income tax shows a gain of P$64,409 million in 9M25 (vs. a loss of P$556,137 million in 9M24). Losses related to current income tax amount to P$145,789 million in 9M25 (vs. a loss of P$28,975 million in 9M24), and the income tax charge related to the application of the deferred tax method in 9M25 is a gain of P$210,198 million (vs. a loss of P$527,162 million in 9M24).

Income tax for 9M25 includes a loss of P$40,574 million corresponding to the consolidation of TMA’s results.

Consolidated Net Financial Debt

As of September 30, 2025, our net financial debt (cash, cash equivalents – net of Client Funds - plus financial investments and financial NDF* minus loans) is negative and amounted to P$4,433,988 million, which represents an increase of P$1,360,474 when compared to the net financial debt as of December 31, 2024, restated by inflation. This increase was mainly driven by the financing obtained for the acquisition of TMA.

* Contemplates rate swaps and NDF (non-delivery forwards) agreements.

Many factors could cause actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements that may be expressed or implied by forward-looking statements. These factors include, among others: (i) the Company’s ability to successfully implement our business strategy and to achieve synergies resulting from the Merger and/or the Acquisition; (ii) the Company’s ability to introduce new products and services that enable business growth; (iii) uncertainties relating to political and economic conditions in Argentina, Paraguay, Uruguay and the United States, including the policies of the new government in Argentina; (iv) the impact of political developments, including the policies of the new government in Argentina, on the demand for securities of Argentine companies; (v) inflation, the devaluation of the peso, the Guaraní and the Uruguayan peso and exchange rate risks in Argentina, Paraguay and Uruguay; (vi) restrictions on the ability to exchange Argentine or Uruguayan pesos or Paraguayan guaraníes into foreign currencies and transfer funds abroad; (vii) the impact of currency and exchange measures or restrictions on our ability to access the international markets and our ability to repay our dollar-denominated indebtedness; (viii) the creditworthiness of our actual or potential customers; (ix) the nationalization, expropriation and/or increased government intervention in companies; (x) technological changes; (xi) the impact of legal or regulatory matters, changes in the interpretation of current or future regulations or reform and changes in the legal or regulatory environment in which the Company operates, including regulatory developments such as sanctions regimes in other jurisdictions (e.g., the United States) which impact on the Company’s suppliers; (xii) the effects of increased competition; (xiii) reliance on content produced by third parties; (xiv) increasing cost of the Company’s supplies; (xv) inability to finance on reasonable terms capital expenditures required to remain competitive; (xvi) fluctuations, whether seasonal or in response to adverse macro-economic developments, in the demand for advertising; (xvii) the Company’s ability to compete and develop our business in the future; (xviii) the impact of increased national or international restrictions on the transfer or use of telecommunications technology; and (xix) the impact of the outbreak of COVID-19 on the global economy and specifically on the economies of the countries in which we operate, as well as on our operations and financial performance. Many of these factors are macroeconomic and regulatory in nature and therefore beyond the control of the Company’s management. Should one or more of these risks or uncertainties materialize, or underlying assumptions prove incorrect, actual results may vary materially from those described herein as anticipated, believed, estimated, expected, intended, planned or projected. The Company does not intend and does not assume any obligation to update the forward-looking statements contained in this document.
