These unaudited condensed consolidated financial statements have been measured in terms of current pesos as of March 31, 2026, applying the guidance in IAS 29. (See Note 1.d).

We have not recast our annual consolidated financial statements to measure them in terms of current pesos as of March 31, 2026, the most recent financial period for which consolidated financial statements are available.

The figures as of December 31, 2025 and for the three month period ended March 31, 2025, which are disclosed in these unaudited condensed consolidated financial statements for comparative purposes, are a result of restating the consolidated financial statements as of such dates, according to what is described in section d). When applicable, certain reclassifications were made for comparative purposes.

TELECOMARGENTINA S.A.

As disclosed in Note 29 to our annual consolidated financial statements as of December 31, 2025, the Company has consolidated TMA as from February 24, 2025 (the “Acquisition date”), and, therefore, the results for the three month period ended March 31, 2026, are not comparable to the comparative information presented in these unaudited condensed consolidated financial statements.

These unaudited condensed consolidated financial statements contain, in addition to all disclosures required under IAS 34, some disclosures required by the LGS and/or by the CNV.

These unaudited condensed consolidated financial statements as of March 31, 2026, were authorized for issuance and approved by resolution of the Board of Directors’ meeting held on May 11, 2026.

b)	Segment information

The Executive Committee and the CEO have a strategic and operational vision of Telecom as a single business unit in Argentina, according to the current regulatory context of the converged ICT Services industry (adding to the same segment the activities related to mobile services, internet services, cable television and fixed and data services, services governed by the same regulatory framework of ICT Services). To exercise its functions, both the Executive Committee and the CEO receive periodically the economic-financial information of Telecom Argentina and its subsidiaries located in Argentina except TMA (stated in historic currency at the transaction date), that is prepared as a single segment and evaluate the evolution of business as a unit of generation of results, administrating the resources in a unique way to achieve the objectives. Regarding costs, they are not specifically allocated to a type of service, considering that Telecom Argentina has a single payroll and operating expenses that affect all services in general (non-specific). Further, decisions on CAPEX affect all the types of services provided by Telecom Argentina and its subsidiaries located in Argentina except TMA and are not allocated specifically to one of them.

Additionally, TMA is identified as a different reportable segment, “ICT Services provided in Argentina – TMA Network” corresponding to the provision of mobile and fixed telephony services, fixed broadband, and video services on a nationwide scale in Argentina, using its own networks, with its own infrastructure. The subsidiary TMA is managed as a separate business unit, and therefore, the Executive Committee and the CEO review its economic and financial information (stated in historic currency at the transaction date) separately. Regarding costs, they are not specifically allocated to a type of service, considering that TMA has a single payroll and operating expenses that affect all services in general (non-specific). Further, decisions on CAPEX affect all the types of services provided by TMA and are not allocated specifically to one of them.

Additionally, Telecom carries out activities abroad (Paraguay, USA, Uruguay and Chile).

The operations that Telecom develops abroad are not analyzed as a separate segment by the Executive Committee and the CEO, considering that they are not considered as individually significant. These operations do not meet the aggregation criteria established by the standard to be grouped within the "ICT Services provided in Argentina – Personal Network" and “ICT Services provided in Argentina – TMA Network” segments, and considering that they do not exceed any of the quantitative thresholds identified in the standard to qualify as reportable segments, they are grouped within the category "Other segments". For the three-month period ended March 31, 2025, the “Other segments” category also included fintech activities in Argentina carried out through Micro Sistemas, as such activities did not meet the criteria to be reported as a separate operating segment.

The Executive Committee and the CEO continue to monitor these businesses to evaluate the manner in which its performance is reviewed and, eventually, its consideration as a separate reportable segment provided it complies with the requirements established by IFRS Accounting Standards to that effect.

As a result, segments as of March 31, 2026 and 2025, are the following:

-	ICT<br> Services provided in Argentina – Personal Network.
-	ICT<br> Services provided in Argentina – TMA Network.
-	Other<br> segments.

The Executive Committee and the CEO evaluate the profitability for each reportable segment based on the measure of the Adjusted EBITDA. Adjusted EBITDA is defined as our net (loss) income less income tax, financial results, earnings (losses) from associates and joint ventures, and gains recognised when control of subsidiary is lost, and depreciation, amortization and impairment of Fixed and Intangibles Assets, reviewing this information in the currency of the date of each transaction.

Presented below is the Segment financial information for the three month periods ended March 31, 2026 and 2025:

c)	Net Earnings per Share
---	---

Basic earnings per share is calculated by dividing the net income attributable to the Controlling Company by the weighted average number of ordinary shares outstanding during the period. On the other hand, diluted earnings per share is computed by dividing the net income attributable to the Controlling Company for the period by the weighted average number of common shares issued and dilutive potential common shares at the closing of the period. Since Telecom Argentina has no dilutive potential common stock outstanding, diluted earnings per share and basic earnings per share are the same.

For the three month periods ended March 31, 2026, and 2025 the weighted average number of shares outstanding amounted to 2,153,688,011.

d)	Financial reporting in hyperinflationary economies

Fair value hierarchy and other disclosures

The measurement at fair value of the financial instruments of Telecom are classified according to the three levels set out in IFRS 13:

-	Level 1: Fair value determined by quoted prices (unadjusted) in active markets for identical assets or<br>liabilities.
-	Level 2: Fair value determined based on inputs other than quoted prices included within Level 1 that are<br>observable for the asset or liability, either directly (e.g. as prices) or indirectly (e.g. derived from prices).
---	---
-	Level 3: Fair value determined by unobservable inputs where the reporting entity is required to develop<br>its own assumptions.
---	---

Financial assets and liabilities recognized at fair value as of March 31, 2026, and December 31, 2025, and the level of hierarchy are listed below:

(1)	The Mutual funds are included in Cash and cash equivalents and<br>Investments. The Government bonds are included in Investments.
---	---
(2)	The fair value is based on information obtained from active markets and corresponds to quoted market prices<br>as of period-end. A market in which transactions for the asset or liability take place with sufficient frequency and volume to provide<br>pricing information on an ongoing basis.
---	---
(3)	The fair value was determined by the variation between the quoted values of certain public securities<br>in foreign currency and Argentine pesos.
---	---
(4)	In 2025, the subsidiary Micro Sistemas, as part of its liquidity management strategy, derecognized its<br>consumer loan portfolio through a non-recourse sale, transferring the related contractual rights in a manner that met the requirements<br>for derecognition under IFRS 9. As the transfer was carried out on a non-recourse basis, the Company retained no continuing involvement<br>and therefore has no future exposure to credit risk. These financial assets had been measured at FVPL. The fair value of the portfolio<br>sold was determined using a discounted cash-flow approach, applying the discount rate specific to each loan.
---	---
(5)	The fair value of financial instruments that are not negotiated in active markets is determined using<br>valuation techniques. These valuation techniques maximize the use of market observable information, when available, and rely as little<br>as possible on specific estimates of the Company. The techniques used for the measurement of financial instruments, are detailed below:<br>a) DFI for forward purchases of US dollars, corresponds to the variation between the market prices at the end of the fiscal year and the<br>time of agreement.
---	---

In relation to the fair values set forth above, as of March 31, 2026, there were no changes in the methods and assumptions used with respect to what was reported in Note 23 to the annual consolidated financial statements as of December 31, 2025.

The Company also has certain financial instruments that are not measured at fair value for which the book value approximates their fair value, except for:

Borrowings

As of March 31, 2026, the fair value of borrowings is as follows:

	Carrying Value	Fair Value
Notes	4,494,070	4,532,412
Other<br> borrowings	993,520	990,185
	5,487,590	5,522,597

**F-25**

TELECOM ARGENTINAS.A.

The fair value of the loans was assessed as follows:

a)	The fair value of Notes traded in active markets was measured based on quoted market prices at the end<br>of the reporting period. As a result, its valuation classifies as Level 1.
b)	The fair value of Notes that are not traded in an active market was measured based on quotes provided<br>by first-tier financial entities, so their valuation qualifies as Level 2.
---	---
c)	For the rest of the borrowings, the fair values were calculated based on cash flows discounted using a<br>current lending rate, so as they are classified as level 3.
---	---

NOTE 12 – PURCHASE COMMITMENTS

The Company has entered into various purchase commitments with domestic and foreign suppliers amounting to approximately $1,574,388 million (of which $392,691 million corresponds to Fixed and Intangible Assets commitments) and $1,711,750 million (of which $426,624 million corresponds to Fixed and Intangible Assets commitments) as of March 31, 2026 and December 31, 2025, respectively. These purchase commitments include those that contain “take or pay” clauses, which force the buyer to purchase a quantity of a product or service in a period, usually annually, or, alternatively, to pay that amount even if it has not been taken or accepted to receive it.

The transactions discussed above were made on arm length transaction basis. When Telecom Argentina’s transactions represented more than 1% of its total shareholders’ equity, they were approved according to Law No. 26,831, the Bylaws and the Executive Committees’ Faculties and Performance Regulation.

NOTE17 – REGULATORY IMPACT OF THE ACQUISITION OF TMA (“THE ACQUISITION”)

As of the date of these unaudited condensed consolidated financial statements, Telecom Argentina has duly and timely made all required presentations related to the acquisition of TMA and has initiated the necessary proceedings before the CNDC and ENACOM in order to obtain (i) the antitrust approval from the Secretary of Industry and Commerce (or from any succeeding enforcement authority under Law No. 27,442, as applicable) for the economic concentration resulting from the Acquisition, and (ii) the approval of ENACOM to the change of control that occurred in TMA as a consequence of the Acquisition. The filing before the CNDC was made on March 3, 2025, while the filing before ENACOM was made on March 7, 2025, both in accordance with the applicable regulatory framework.

Both administrative procedures are currently underway. On March 21, 2025, the Secretary of Industry and Commerce issued the Resolution No. 63/2025, requiring Telecom Argentina as a provisional measure in accordance with Article 44 of Law No. 27,442, to refrain, for a period of six months or until the Secretary of Industry and Commerce issues a decision pursuant to Article 14 of Law No. 27,442 either approving or subordinating the acquisition to the fulfillment of conditions, or denying authorization of the transaction—whichever occurs first—from carrying out any legal, corporate or commercial act relating directly or indirectly to the integration or consolidation of TMA’s businesses with Telecom Argentina. This included any initiative that entails integrating TMA’s equipment with that of Telecom Argentina, as well as any exchange of competitively sensitive information with TMA, such as prices and pricing strategies, costs and margins, business plans and commercial strategies, information on customers and suppliers, investment plans, among others. Telecom Argentina must also respect the agreements regarding the reciprocal use of infrastructure previously entered into between Telecom Argentina and TMA. The Resolution does not modify the manner in which Telecom Argentina and TMA operate. As of the date of these unaudited condensed consolidated financial statements, TMA operates as an independent business under a separate business segment from “ICT Services provided in Argentina – Personal Network”, and the members of the Board of Directors and the management of Telecom Argentina and TMA are independent of each other.

On April 6, 2025, Telecom Argentina filed an appeal before the Secretary of Industry and Commerce and the CNDC against the Resolution No. 63/2025, as well as against the note from the Secretary of Industry and Commerce dated March 27, 2025 to the CNDC appointing a monitoring agent for the Telecom Argentina and TMA to oversee compliance with the measure. On June 5, 2025, Telecom Argentina was notified of the decision issued by Chamber III of the Federal Civil and Commercial Court of Appeals, which granted the appeal with suspensive effect and ordered the Secretary of Industry and Commerce to refrain from adopting any measure that would contravene the suspensive effect with which the appeal was granted.

**F-29**

TELECOMARGENTINA S.A.

In addition, on June 19, 2025, Telecom Argentina was notified of a resolution by the Secretary of Industry and Commerce that included (i) a statement of objection to the transaction (“Preliminary Objection Report”); (ii) a request for Telecom Argentina to present its arguments against the objections within 15 days, and (iii) a call for a special hearing to consider the measures proposed by Telecom Argentina to overcome these objections.

This resolution does not represent a final resolution or the imposition of penalties, but rather a procedural stage affording the parties the opportunity to exercise their right of defense, submit responses, or propose commitments to mitigate potential anticompetitive effects.

Telecom Argentina believes that the aforementioned Preliminary Objection Report was issued and notified prematurely, at an early stage of the process, without all the necessary information being considered and before all relevant procedures established under the antitrust laws were completed. In this regard, Telecom Argentina does not agree with the preliminary conclusions expressed in the Preliminary Objection Report and has focused on analyzing all CNDC statements therein and submitting all appropriate presentations and technical data in response to the report (including Form F-2 as required by antitrust law, which was submitted by Telecom Argentina on June 29, 2025) to advance the review process and obtain the relevant approvals.

On August 5, 2025, Telecom Argentina duly and timely submitted its response to the Preliminary Objection Report issued by the CNDC. Together with that submission, and without this being construed in any way as an acknowledgment that the transaction raises an antitrust concern, Telecom Argentina expressed its willingness, as a procedural safeguard contemplated under Law No. 27,442, to consider potential commitments to address the provisional concerns outlined in the Preliminary Objection Report, should the authorities deem it necessary. Telecom Argentina believes that any such potential commitments, if required, would be limited, proportionate, and would not have a material adverse effect on Telecom Argentina’s business, financial condition, or ability to meet its financial obligations.

Subsequently, the CNDC held the special hearing provided for in Article 14 of Law No. 27,442. The first hearing took place on September 19, 2025, and the second hearing on October 6, 2025, at which time the CNDC decided to adjourn the proceedings, leaving their continuation subject to the CNDC’s evaluation of the observations and submissions previously made by Telecom Argentina, as well as of the information still pending submission by third parties at the CNDC’s request.

On November 17, 2025, pursuant to Decree No. 810/2025, the Argentine government established the ANC, a decentralized and autonomous entity that replaced the CNDC. The ANC became operational upon the appointment of its authorities in accordance with Law No. 27,442, which designates the ANC as the body responsible for protecting and promoting competition and safeguarding the general economic interest. As a result, the regulatory review of the Acquisition is conducted under the supervision of the ANC.

On December 23, 2025, Chamber III of the National Court of Appeals in Civil and Commercial Matters issued its decision regarding the appeal filed by Telecom Argentina against Resolution No. 63/2025 of the Secretary of Industry and Commerce. The Court held that it had become moot to rule on the appeal, given that at the time the judgment was rendered, the precautionary measure had already expired. In this regard, the Chamber expressly stated that no evidence had been submitted in the case file demonstrating an extension of the precautionary measure and therefore concluded that there was no longer an existing case or controversy that would warrant consideration of the appeal. The Argentine Government filed a Federal Extraordinary Appeal against this resolution, which has been notified to Telecom Argentina on February 23, 2026. Telecom Argentina has duly responded within the established timeframe, requesting that the appeal be dismissed as inadmissible.

Likewise, on that same date, a new hearing was held within the framework of the procedure established in Article 14 of Law No. 27,442 before the ANC, which constituted a continuation of the previously mentioned hearings. With this hearing, the hearing stage was deemed concluded, leaving the case under review by the ANC for the issuance of the corresponding resolution within the framework of the operation’s review process, having concluded the stage of submissions and hearings contemplated in the procedure.

Telecom Argentina will exercise all rights available to it to review or challenge any decisions that it considers to be inconsistent with applicable Argentine law or the actual competitive conditions in each relevant market and jurisdiction.

Although there can be no assurance regarding the outcome of the post-closing review of the Acquisition by regulatory authorities, Telecom Argentina and its legal advisors have arguments to support its position.

NOTE18 – RECENT DEVELOPMENTS CORRESPONDING TO THE THREE-MONTH PERIOD ENDED MARCH 31, 2026

a)	Agreement between Telecom Argentina, MFH and Micro Sistemas with Banco Macro S.A.

On January 22, 2026, Telecom Argentina and its direct and indirect subsidiaries MFH and Micro Sistemas have entered into a framework agreement with Banco Macro S.A. (“Banco Macro”) aimed at fostering the growth and expansion of the business of Micro Sistemas, a payment services provider operating under the “Personal Pay” brand.

This strategic alliance will enable the development of a differentiated and comprehensive value proposition for customers operating on the “Personal Pay” platform, while also expanding the range of financial products and services offered to a broader customer base, supported by Banco Macro’s leading position in the financial sector.

For these purposes, Banco Macro will contribute its expertise in financial products, while Micro Sistemas will contribute its extensive base of active customers and recurring use cases with genuine transaction activity, thereby promoting a more efficient and broader market with customers at its core.

Pursuant to this agreement, Banco Macro made a capital contribution and, therefore, subscribed for shares representing 50% of the share capital and voting rights of Micro Sistemas, for an amount in pesos equivalent to US$75 million.

As a result of this transaction, Telecom no longer holds the majority of the voting rights required to exercise control over Micro Sistemas and, accordingly, when control of a subsidiary is lost, a gain or loss is recognised on the portion of the retained interest in addition to the gain or loss on the portion no longer owned (full gain recognition) of $45,615 million, which is presented under the line item “Earnings from associates and joint ventures, and gains recognised when control of subsidiary is lost” in the unaudited condensed consolidated income statements.

Consequently, as of January 22, 2026, Telecom’s interest in Micro Sistemas amounts to 50%, and given that joint control exists, the investment in this company is measured and presented in these unaudited condensed consolidated financial statements as a joint venture.

The transaction is subject to the corresponding approval by the National Antitrust Authority, in accordance with applicable regulations.

b)	Regulatory Framework – Universal Service Fund (FFSU)

With reference to the information disclosed in Notes 2.d) ii) 1) and 29 to our annual consolidated financial statements as of December 31, 2025, on January 22, 2026 Telecom Argentina and TMA expressed their intention to adhere to the payment plan established by ENACOM, with the purpose of aligning its situation within the framework set forth by Resolution No. 3/2026 with respect to the matters included therein.

On March 30, 2026, Telecom Argentina and TMA received notification of the final amount of the debt, which was assessed in terms of its economic convenience, taking advantage of the opportunity for a significant reduction in the interest applied to the recognized debts contemplated under the regime. Consequently, Telecom Argentina and TMA confirmed their final adherence to the Payment Facilities Plan.

In this regard, on April 6, 2026, total payments of $24,739 million and $30,107 million were made, corresponding to Telecom Argentina and TMA, respectively. Of this total, $21,670 million and $28,825 million attributable to Telecom Argentina and TMA, respectively, are related to FFSU and include $8,239 million and $10,246 million in interest, respectively. The remaining payments correspond to balance differences identified during audit processes and to fines arising from sanctions imposed under compliance with regulatory requirements, as well as other costs. This thereby resolves the contingency identified in Notes 2.d) ii) 1) and 29 of the annual consolidated financial statements.

c)	Income tax - Actions for recourse filed with the Tax Authority – Telecom Argentina

In relation to the information disclosed in Note 13 to our annual consolidated financial statements as of December 31, 2025, regarding fiscal year 2009, during the period the principal tax liability plus accrued interest from ARCA was settled.

**F-31**

TELECOMARGENTINA S.A.

Consequently, during the three-month period ended March 31, 2026, Telecom Argentina recognized the credit related to interest of $355 million.

As of the date of these unaudited condensed consolidated financial statements, the outstanding receivable amounts to $453 million ($98 million corresponding to the claimed principal and $355 million to interest).

NOTE19 – SUBSEQUENT EVENTS

a)	Provisions of the Telecom Argentina Ordinary and Extraordinary Shareholders’ meeting

At the Ordinary and Extraordinary Shareholders’ Meeting held on April 29, 2026, the shareholders of Telecom Argentina decided, among other:

(i)   To approve the Board of Directors’ proposal stated in current currency as of March 31, 2026 using the National Consumer Price Index pursuant to CNV Resolution No. 777/18 in connection with the Accumulated retained losses as of December 31, 2025 for $(135,642) million in current currency as of March 31, 2026: (a) absorb the amount of $135,642 million in current currency as of March 31, 2026 to “Voluntary reserve to maintain the Company's level of capital expenditures and its current solvency level”; and (b) to reclassify the amount of $126,397 million in current currency as of March 31, 2026 from “Voluntary reserve to maintain the Company's level of capital expenditures and its current solvency level” and to be charged against the “Contributed Surplus”; and

(ii)  to delegate on the Board of Directors the power to reverse, before December 31, 2026 the “Voluntary reserve to maintain the Company's level of capital expenditures and its current solvency level” in an amount that allows distribution of dividends in cash or in non-cash or any combination of both options, for up to the maximum amount of distribution of US$ 300 million.

b)	Provisions of the Núcleo General Ordinary Shareholders’ meeting

The Núcleo General Ordinary Shareholders’ meeting held on April 23, 2026, among other issues, approved the distribution of dividends of 670,000 million of Guaraníes (equivalent to approximately $145,050 million as of the date of the meeting), corresponding to Unallocated earnings from previous years, of which 452,250 million of Guaraníes (equivalent to approximately $97,909 million) correspond to Telecom Argentina and 217,750 million of Guaraníes (equivalent to approximately $47,141 million) correspond to the non-controlling shareholder. The mentioned dividends will be available to shareholders during the first semester of 2026.

Adjusted<br> EBITDA is a non-GAAP measure, defined as our net income, less income tax, financial results<br> (Financial results from borrowings and other financial results, net), earnings from associates<br> and joint ventures, and gains recognised when control of subsidiary is lost, and depreciation,<br> amortization and impairment of Fixed and intangible assets. For further information on the<br> use of adjusted EBITDA, see “Adjusted EBITDA”.

In 1Q26, net income amounted to P$642,984 million compared to P$123,593 million in 1Q25, representing 27.3% and 6.8% of consolidated revenues in 1Q26 and 1Q25, respectively.

The increase in net income in 1Q26 was mainly due to an increase in financials gains and higher earnings from associates and joint ventures, and gains recognised when control of subsidiary is lost for P$533,885 million and an increase of P$147,374 million in operating income, partially offset by a higher income tax expense of P$161,868 million.

Net income attributable to controlling company amounted to P$636,682 million in 1Q26 compared to P$118,100 million in 1Q25.

It should be noted that the variations are partially explained by the fact that 1Q26 includes the full results for TMA for the quarter, whereas 1Q25 includes only the results from the acquisition date. The results of 1Q26 contain an income of P$82,055 million corresponding to the consolidation of TMA’s results (excluding the effects of intercompany transactions), while in 1Q25 such consolidation generated a loss of P$28,715 million.

During 1Q26 revenues increased 30.5% compared to 1Q25, amounting to P$2,357,686 million compared to P$1,806,103 million in 1Q25. The increase in revenues was mainly due to effect of the consolidation of TMA’s results of P$561,725 million (excluding the effects of intercompany transactions) when comparing 1Q26 for the full period with 1Q25 from the Acquisition date. As a result of the restatement in current currency as of March 31, 2026, revenues included a restatement effect of P$74,849 million and P$480,937 million in 1Q26 and 1Q25, respectively. For further information about revenue see “Explanations by segments” below.

TELECOMARGENTINA S.A.

Total operating costs without depreciation, amortization and impairment of Fixed and Intangible Assets totaled P$1,538,195 million in 1Q26, representing an increase of P$331,404 million or 27.5% compared to 1Q2025. The increase was mainly due to the effect of the consolidation of TMA’s results of P$408,850 million (excluding the effects of intercompany transactions) when comparing 1Q26 for the full period with 1Q25 from the Acquisition date. As a result of the restatement in current currency as of March 31, 2026, the restatement effect included in operating costs without depreciation, amortization and impairment of Fixed and intangible Assets amounted to P$79,591 million and P$331,639 million in 1Q26 and 1Q25, respectively. For further information regarding operating costs without depreciation, amortization and impairment of Fixed and Intangible Assets see “Explanations by segments” below.

Depreciation,amortization and impairment of Fixed and Intangible Assets

Depreciation, amortization and impairment of Fixed and Intangible Assets amounted to P$523,733 million in 1Q26, representing an increase of P$72,805 million or 16.1% compared to 1Q25.

The increase was mainly due to the effect of the consolidation of TMA’s results of P$84,110 million when comparing 1Q26 for the full period with 1Q25 from the Acquisition date. Excluding this impact, depreciation, amortization and impairment of Fixed and Intangible Assets decreased mainly due to the effect of those assets that ended their useful life after March 31, 2025, partially offset by the depreciation and amortization of registrations after that date, which, in turn, decreased compared to 1Q25.

As a result of the restatement in current currency as of March 31, 2026, the restatement effect included in depreciation, amortization and impairment of Fixed and Intangible Assets amounted to P$304,173 million and P$363,738 million in 1Q26 and 1Q25, respectively.

Operatingincome

Operating income in 1Q26 amounted to P$295,758 million compared to an operating income of P$148,384 million in 1Q25. Operating income represented 12.5% and 8.2% of revenues in 1Q26 and 1Q25, respectively.

The increase was mainly due to the effect of the consolidation of TMA’s results of P$68,765 million when comparing 1Q26 for the full period with 1Q25 from the Acquisition date. Additionally the improvement in the operating margin is mainly attributable to an increase in the Adjusted EBITDA, which reached 34.8% of our consolidated revenues in 1Q26, compared to 33.2% in 1Q25. For further details, see “Explanations by segments” below. In addition, an improvement is observed in the Depreciation, amortization and impairment of Fixed and Intangible Assets margin over revenues, which decreased to 22.2% in 1Q26, compared to 25.0% in 1Q25, as a result of the effects described in section “Depreciation, amortization and impairment of Fixed and Intangible Assets” above.

TELECOMARGENTINA S.A.

Telecom incurred a net financial gain of P$630,864 million in 1Q26, compared to a net financial gain of P$133,876 million in 1Q25.

The variation in financial results, net for 1Q26 was mainly driven by a higher gain from foreign exchange differences, measured in real terms, of P$530,164 million, reflecting the impact of an inflation rate of 32.6% and an appreciation of the U.S. dollar against the Argentine peso of 28.7%, compared to an inflation rate of 55.9% and an appreciation of the U.S. dollar of 25.2% in 1Q25. Additionally, it should be noted that, on a nominal basis, in 1Q26 there was a depreciation of the U.S. dollar against the Argentine peso of 5.0%, whereas in 1Q25 there was an appreciation of the U.S. dollar of 4.1%. Furthermore, the increase in foreign exchange gains was partially attributable to a higher level of U.S. dollar-denominated borrowings in 2026, which resulted in increased exposure to fluctuations in the Argentine peso relative to the U.S. dollar. Furthermore, positive RECPAM increased by P$38,435 million and there was a higher gain from changes in the fair value of financial assets at FVPL of P$20,816 million, resulting from the 32.6% inflation impact on the quoted value of such instruments (compared to 55.9% inflation in 1Q25).

These factors were partially offset by higher interest on borrowings of P$63,512 million, higher losses from financial discounts on assets, debts and others of P$21,849 million, and a lower gain from remeasurement in borrowings of P$7,234 million, since the UVA adjustment exceeded inflation, generating negative results in real terms.

Additionally, the effect of the consolidation of TMA’s results amounted to P$13,701 million when comparing 1Q26 for the full period with 1Q25 from the Acquisition date.

AdjustedEBITDA

An important operational performance measure used by the Company’s Chief Operating Decision Maker (as this term is defined in IFRS Accounting Standards 8) is Adjusted EBITDA. Adjusted EBITDA is defined as our net income, less income tax, financial results, earnings from associates and joint ventures, and gains recognised when control of subsidiary is lost, and depreciation, amortization and impairment of Fixed and Intangible Assets. We believe Adjusted EBITDA facilitates company-to-company operating performance comparisons by backing out potential differences caused by variations such as capital structures, taxation and the useful lives and book depreciation and amortization of PP&E and intangible assets, which may vary for different companies for reasons unrelated to operating performance. Although Adjusted EBITDA is not a measure defined in accordance with IFRS Accounting Standards (a non-GAAP measure), our Management believes that this measure facilitates operating performance comparisons from period to period and provides useful information to investors, financial analysts and the public in their evaluation of our operating performance. Adjusted EBITDA does not have a standardized meaning and, accordingly, our definition of Adjusted EBITDA may not be comparable to Adjusted EBITDA as used by other companies.

Revenues forICT Services provided in Argentina – Personal Network are comprised as follows:

MobileServices

Mobile services revenues in 1Q26 amounted to P$640,342 million, representing an increase of P$46,799 million, or 7.9%, as compared to 1Q25, and were the principal contributor to our total services revenues for ICT Services provided in Argentina – Personal Network in 1Q26, accounting for 46% of services revenues in 1Q26 compared to 45% in 1Q25. Mobile internet services revenues represented 94% of the mobile services revenues in 1Q26 and 1Q25.

The effect generated by the restatement in current currency as of March 31, 2026, included in Mobile services revenues amounted to P$19,851 million and P$160,180 million in 1Q26 and 1Q25, respectively.

This increase was mainly due to an 18.7% increase in ARPU, partially offset by an 8.9% decrease in the number of customers.

ARPU amounted to P$10,766.4 in 1Q26 compared to P$9,066.5 in 1Q25. This increase was mainly explained by price increases. The effect generated by the restatement in current currency as of March 31, 2026, included in ARPU amounted to P$351.6 and P$2,445.7 in 1Q26 and 1Q25, respectively.

TELECOM ARGENTINA S.A.

The customer base amounted to 19.4 million and 21.3 million as of March 31, 2026, and 2025, respectively. The decrease is mainly due to: (a) a change implemented in June 2025 for the prepaid customer base in the measurement of line useful life, which was reduced from 360 days to 242 days to consider the definitive disconnection since the last top-up date, resulting in a 12.2% reduction in the prepaid customer base (this methodological change had no material impact on revenues or ARPU comparability, as those prepaid customers contribute less to total revenues than postpaid customers); and (b) higher disconnections in postpaid customers, associated with changes in commercial strategies, with the postpaid customer base declining by 3.7%. As of March 31, 2026, 59% of total mobile customers were prepaid customers and 41% were postpaid customers, compared to 61% and 39%, respectively, as of March 31, 2025. Additionally, the average monthly churn rate amounted to 2.4% in 1Q26 compared to 2.0% in 1Q25.

ARPU of Mobile Services in ICT Services provided in Argentina – Personal Network

A monthly operational measure used in the mobile services is ARPU, which we calculate by dividing adjusted total service revenues—excluding out collect wholesale roaming, cell site rental, reconnection fees revenues and others— by the average number of customers in 1Q26 and then annualizing it. ARPU is not a measure calculated in accordance with IFRS Accounting Standards and our measure of ARPU may not be calculated in the same manner as similarly titled measures used in the TIC business. Certain components of service revenues are excluded from Personal’s ARPU calculations presented. Management believes this measure is helpful in assessing the development of the subscriber base of mobile services. The following table shows the reconciliation of total service revenues to such revenues included in the ARPU calculations:

	1Q26
	(P million)
Total Mobile service revenues	640,342
Components<br> of service revenues not included in the ARPU calculation: out collect wholesale roaming, cell sites rental, reconnection fees revenues<br> and others	(816)

Average<br> number of customers during the period (millions)	19.8
ARPU of Mobile Services – Personal Network	10,766.4

All values are in US Dollars.

InternetServices

Internet services revenues amounted to P$357,709 million in 1Q26 (equivalent to 26% and 27% of total services revenues for ICT Services provided in Argentina – Personal Network in 1Q26 and 1Q25, respectively), decreasing P$7,440 million or 2.0%, as compared to P$365,149 million in 1Q25.

The effect generated by the restatement in current currency as of March 31, 2026, included in internet services revenues amounted to P$11,115 million and P$98,623 million in 1Q26 and 1Q25, respectively.

The decrease in internet services revenues in 1Q26 was mainly due to the decrease in ARPU of 5%, partially offset by a 3.3% increase in the customer base.

ARPU amounted to P$28,389.6 in 1Q26 as compared to P$29,887.6 in 1Q25. This decrease in ARPU is mainly explained by temporary adjustments driven by migration processes from xDSL (copper) to FTTH (fiber), which negatively impacted revenues in 1Q26, and by a net effect associated with the growth of the customer base with discounts granted compared to 1Q25. The effect generated by the restatement in current currency as of March 31, 2026, included in ARPU amounted to P$656.6 and P$8,071.3 in 1Q26 and 1Q25, respectively.

The customer base reached 4.2 million as of March 31, 2026, representing a 3.3% increase compared to March 31, 2025. The monthly Internet services churn rate stood at 1.3% in 1Q26 and 1.2% in 1Q25.

Cable Television Services

Cable television service revenues amounted to P$198,772 million in 1Q26 (equivalent to 14% and 15% of total services revenues for ICT Services provided in Argentina – Personal Network in 1Q26 and 1Q25), increasing P$2,666 million or 1.4%, as compared to P$196,106 million in 1Q25.

The effect generated by the restatement in current currency as of March 31, 2026, included in cable television services revenues amounted to P$6,132 million and P$52,924 million in 1Q26 and 1Q25, respectively.

The increase in cable television service revenues in 1Q26 was mainly due to a 0.3% increase in ARPU and a 4.7% increase in the customer base.

ARPU amounted to P$20,077.8 in 1Q26, compared to an ARPU of P$20,015.8 in 1Q25. The increase in ARPU reflects the impact of price increases implemented throughout the year, partially offset by discounts granted to new customers. The effect generated by the restatement in current currency as of March 31, 2026 included in ARPU amounts to P$214.1 and P$4,856.9 in 1Q26 and 1Q25, respectively

As of March 31, 2026, the customer base amounted to 3.3 million customers, representing a 4.7% increase compared to March 31, 2025. The increase in the customer base, observed mainly during February 2026, was driven by a commercial environment that favored higher levels of demand and new service subscriptions in 1Q26. Additionally, the average monthly churn rate amounted to 1.6% and 1.5% in 1Q26 and 1Q25, respectively.

ARPU of Cable Television Services of ICT Services provided in Argentina – Personal Network

An important monthly operational measure used in the Cable Television services is ARPU, which we calculate by dividing adjusted total service revenues - excluding connection and administration fees, advertising services and others—(by the average number of customers in 1Q26 and then annualizing it. ARPU is not a measure calculated in accordance with IFRS Accounting Standards and our measure of ARPU may not be calculated in the same manner as similarly titled measures used in the TIC business. Certain components of service revenues are excluded from Cable Television’s ARPU calculations presented. Management believes this measure is helpful in assessing the development of the subscriber base of cable television services. The following table shows the reconciliation of total cable television service revenues to such revenues included in the ARPU calculation:

All values are in US Dollars.

Fixed andData Services

Revenues generated by fixed and data services amounted to P$138,029 million in 1Q26 (representing 10% and 12% of total services revenues for ICT Services provided in Argentina – Personal Network in 1Q26 and 1Q25, respectively) decreasing P$16,791 million, or 10.8%, as compared to P$154,820 million in 1Q25.

The effect generated by the restatement in current currency as of March 31, 2026, included in fixed and data services revenues amounted to P$4,369 million and P$41,901 million in 1Q26 and 1Q25, respectively.

The decrease was primarily attributable to the Company’s inability to adjust prices at a pace consistent with inflation, considering accumulated inflation of 32.6% over the last twelve months, partially offset by an increase of 3.8% in the customer base.

The customer base amounted to 2.8 million (of which 2.4 million are IP fixed telephony service base) in 1Q26, compared to 2.7 million in 1Q25 (of which 1.9 million are IP fixed telephony service base).

Other servicesrevenues

Other services revenues generated by other services amounted to P$45,064 million in 1Q26 (equivalent to 3% and 1% of total services revenues for ICT Services provided in Argentina – Personal Network in 1Q26 and 1Q25, respectively), increasing P$26,511 million as compared to P$18,553 million in 1Q25.

The effect generated by the restatement in current currency as of March 31, 2026, included in other services revenues amounted to $1,333 million and $4,862 million in 1Q26 and 1Q25, respectively.

The increase in 1Q26 compared to 1Q25 is mainly due to interconnection services provided to the ICT Services segment in Argentina – TMA Network provided during 1Q26. These revenues are eliminated at the consolidated level as part of the consolidation process, as they constitute a transaction between subsidiaries.

TELECOM ARGENTINA S.A.

Equipment

Equipment revenues amounted to P$47,694 million in 1Q26 (representing 3.3% of total revenues for ICT Services provided in Argentina – Personal Network), decreasing P$33,231 million, or 41.1%, as compared to P$80,925 million in 1Q25.

The effect generated by the restatement in current currency as of March 31, 2026, included in equipment revenues amounted to P$1,258 million and P$21,884 million in 1Q26 and 1Q25, respectively.

The decrease was mainly due to the fact that the Company was unable to increase its prices to the same extent as the increase in inflation, and a decrease in the number of mobile handsets sold compared to 1Q25.

Operatingcosts (without depreciation, amortization and impairment of Fixed and Intangible Assets) for ICT Services provided in Argentina –Personal Network are comprised as follows:

Operating costs (without depreciation, amortization and impairment of Fixed and Intangible Assets) for ICT Services provided in Argentina – Personal Network totaled P$894,502 million in 1Q26, representing a decrease of P$26,929 million or 2.9% compared to P$921,431 million in 1Q25.

The effect generated by the restatement in current currency as of March 31, 2026, included in Operating costs (without depreciation, amortization and impairment of Fixed and Intangible Assets) amounted to P$36,506 million and P$261,307 million in 1Q26 and 1Q25, respectively.

Employeebenefit expenses and severance payments

Employee benefit expenses and severance payments increased P$5,486 million or 1.8%, amounting to P$318,759 million in 1Q26 as compared to P$313,273 million in 1Q25.

The effect generated by the restatement in current currency as of March 31, 2026, included in Employee benefit expenses and severance payments amounted to P$9,534 million and P$84,719 million in 1Q26 and 1Q25, respectively.

The increase was mainly driven by higher severance charges amounting to P$24,824 million, partially offset by a decrease in salary expenses of P$18,540 million. The decrease in salary expenses is mainly due to a reduction in net headcount (17,503 Telecom Argentina employees as of March 31, 2026, representing an 8.8% decrease compared to March 31, 2025), partially offset by salary increases for both employees covered by collective bargaining agreements (as agreed by the Company with the various labor unions) and those not covered by such agreements.

Fees forservices, maintenance, materials and supplies

Fees for services, maintenance, materials and supplies decreased P$25,733 million or 14.3%, amounting to P$154,180 million in 1Q26 as compared to P$179,913 million in 1Q25.

The effect generated by the restatement in current currency as of March 31, 2026, included in Fees for services, maintenance, materials and supplies amounted to P$7,694 million and P$55,463 million in 1Q26 and 1Q25, respectively.

The decrease is mainly explained by a decrease in services received from call centers. In addition, a 4% improvement in the average cost of service fees was recorded compared to 1Q25.

Furthermore, in 1Q26 there was a recovery of the provision for materials obsolescence, together with lower materials consumption. As a result of these factors, service fees decreased by P$21,793 million and maintenance and materials costs declined by P$4,586 million compared to 1Q25.

TELECOM ARGENTINA S.A.

Taxes andfees with the Regulatory Authority

Taxes and fees with the Regulatory Authority, including turnover tax, municipal taxes and other taxes, increased P$2,898 million or 2.5%, amounting to P$120,544 million in 1Q26 as compared to P$117,646 million in 1Q25. Taxes and fees with the Regulatory Authority represent 8.4% and 8.3% of total revenues from ICT Services provided in Argentina - Personal Network in 1Q26 and 1Q25, respectively.

The effect generated by the restatement in current currency as of March 31, 2026, included in Taxes and fees with the Regulatory Authority amounted to P$3,669 million and P$31,727 million in 1Q26 and 1Q25, respectively.

The increase is mainly driven by the effect of tax charges arising from the higher revenue levels described above.

Commissionsand advertising

Commissions and advertising increased P$1,552 million or 2.8%, amounting to P$57,460 million in 1Q26, as compared to P$55,908 million in 1Q25.

The effect generated by the restatement in current currency as of March 31, 2026, included in Commissions and advertising amounted to P$1,611 million and P$15,027 million in 1Q26 and 1Q25, respectively.

The increase is mainly due to higher advertising costs related to Flow campaigns (such as Flow Music, Flow Content, Flow Sports, among others). In addition, there was an increase in expenditure aimed at strengthening the positioning and visibility of the Personal brand, as a result of the branding change that occurred in December 2025.

Programmingand content costs

Programming and content costs increased by P$4,286 million or 5.4%, amounting to P$83,855 million in 1Q26 as compared to P$79,569 million in 1Q25.

The effect generated by the restatement in current currency as of March 31, 2026, included in Programming and content costs amounted to P$2,599 million and P$21,435 million in 1Q26 and 1Q25, respectively.

The increase corresponds to the rise in linear channel services and in the Football Pack.

Other operatingcosts

Other operating expenses (which include legal claims and contingent liabilities, energy and other public services, insurance, postage and travel expenses, rentals and internet capacity, interconnection and transmission costs, cost of equipment, among others) decreased P$15,418 million or 8.8%, amounting to P$159,704 million in 1Q26 as compared to P$175,122 million in 1Q25.

The effect generated by the restatement in current currency as of March 31, 2026, included in Other operating expenses amounts to P$11,399 million and P$52,936 million in 1Q26 and 1Q25, respectively.

The decrease is mainly explained by: i) lower costs of equipment sold: there was a decrease in the number of devices sold compared to 1Q25, offset by fewer commercial actions by the brands, which limited the reduction in equipment acquisition costs; ii) a reduction in legal proceedings and other contingencies, as well as rental and internet capacity costs. These effects were partially offset by an increase in interconnection costs (higher roaming costs) and bad debt expenses.

All values are in US Dollars.

As “general explanation of segment variation” it should be noted that the variations are mainly explained by the fact that 1Q26 includes the full results for the quarter, while 1Q25 includes only the results from the Acquisition date.

Revenues forICT Services provided in Argentina – TMA Network are comprised as follows:

MobileServices

Mobile services revenues in 1Q26 amounted to P$539,745 million, representing an increase of P$356,184 million as compared to 1Q25, and were the principal contributor to total services revenues for ICT Services provided in Argentina – TMA Network in 1Q26, accounting for 64.4% and 63.7% of services revenues in 1Q26 and 1Q25, respectively.

The effect generated by the restatement in current currency as of March 31, 2026, included in Mobile services revenues amounted to P$16,553 million and P$45,136 million in 1Q26 and 1Q25, respectively.

Beyond the general explanation of segment variation described above, the variation was affected by a 3.8% decrease in ARPU and a 1.8% increase in the customer base.

ARPU amounted to P$9,122.8 in 1Q26 compared to P$9,480.6 in 1Q25. This decrease is mainly due to comparability effects between periods. Although postpaid prices increased above inflation, total ARPU decreased due to a higher participation of prepaid customers (which have a lower ARPU than postpaid customers). The effect generated by the restatement in constant currency as of March 31, 2026 included in ARPU amounted to P$281.0 and P$2,331.2 in 1Q26 and 1Q25, respectively.

The customer base amounted to 19.2 million and 18.9 million as of March 31, 2026 and 2025, respectively. As of March 31, 2026, 51% of customers were prepaid and 49% were postpaid, remaining at the same proportion as of March 31, 2025. A change in customer behavior was observed, resulting in a 0.8% increase in the prepaid customer base and a 2.9% increase in the postpaid customer base.

This increase was partially offset by a 15.1% reduction in the customer base, mainly due to customer migration to streaming and OTT platforms and increased competitive pressure.

The increase in cable television service revenues in Paraguay of P$1,262 million is attributable to price increases and to the appreciation of the Guaraní against the Argentine peso (36.6% over the last twelve months), compared to an accumulated inflation rate for the fiscal year of 32.6%.

Liquidityand Capital Resources

Sourcesand Uses of Funds

We expect the main sources of Telecom Argentina’s liquidity in the short term to be cash flows from Telecom Argentina’s operations and cash flows from financing from third parties, which may include accessing to domestic and international capital markets and obtaining financing from financial institutions. Telecom Argentina’s principal uses of cash flows are expected to be capital expenditures, operating expenses, dividend payments to its shareholders, payments of borrowings and for general corporate purposes. Telecom Argentina expects working capital, funds generated from operations, dividend payments from its subsidiaries and financing from third parties to be sufficient. Telecom Argentina assumes that it will be able to access the domestic and international capital markets in 2026 to refinance its outstanding debt, if necessary.

ICT Servicesprovided in Argentina – Personal Network

In terms of infrastructure, during 1Q26, we continued to enhance the services we provide through the deployment of the 4G/LTE network, together with the technological reconversion of our 2G / 3G networks to 4G and LTE and the deployment of fiber optics to connect homes with broadband, which also improved our fixed and data networks.

The deployment of 4G/LTE reached a coverage of 97% of the urban population, and we achieved a coverage of 98% of the population in Argentina’s major cities.

Our mobile network customers with access to our 4G network, according to the latest benchmark conducted by Ookla, experience improved service quality, with average speeds of 84 Mbps.

Additionally, approximately 85% of calls are made via VoLTE, a technology that enables voice calls over the 4G network with significant improvements in audio and video quality. In 1Q26, the Company continued the expansion of its 5G network, incorporating 126 new sites.

Furthermore, we continued deploying mobile site connectivity to achieve better quality and capacity, replacing radio links with high-capacity fiber optic connections. Lastly, we continued with the plan to connect remote and low-density areas through satellite backhaul.

ICT Servicesprovided in Argentina – TMA Network

In terms of fixed access infrastructure, during 1Q26 TMA continued strengthening its broadband capabilities through the deployment of new fiber optic networks and the modernization of existing infrastructure.

During this period, TMA advanced the rollout of fiber in new residential areas, buildings, and commercial zones, connecting more than 58,000 new homes across more than 2,000 blocks. In addition, TMA installed 3,600 new distribution cabinets in already deployed areas to facilitate the connection of new customers.

TMA also made progress in modernizing its access network by replacing obsolete platforms, including the renewal of multiple OLTs, incorporating technology compatible with the XGSPON and 50GSPON evolution paths.

During this period, no new homes were connected through partners or allied networks. As a result of these initiatives, by the end of the quarter TMA reached approximately 5.26 million connected homes, of which 4.2 million correspond to its own network and 1.05 million to partner networks.

In terms of infrastructure, TMA continued to enhance the services it provides through the deployment of the 4G/LTE network and fiber-optic networks to connect homes with broadband, which also positively impacted fixed and data networks. This strategy enabled TMA to differentiate itself from competitors and significantly improve customer Net Promoter Score (NPS).

The 4G/LTE rollout reached coverage of 99.4% of the urban population across 2,218 localities and 100% coverage in Argentina’s main cities as of March 31, 2026. Customers who access TMA’s 4G network benefit from improved quality of service, with speeds of up to 66 Mbps, and approximately 60% of calls are carried out using VoLTE, a technology that enables voice calls over the 4G network, resulting in significant improvements in audio and video quality. In addition, TMA continued deploying mobile connectivity to improve quality and capacity, replacing radio links with high-capacity fiber-optic connections. Regarding 5G, TMA reached a total of 848 sites.
