América Móvil Consolidated Results

The U.S. Government shutdown, in effect through the middle of the fourth quarter, ended up raising uncertainty about the state of economic activity in the U.S. Not only did it have a direct impact on employment but, on account of the shutdown, several economic indicators generated by government agencies failed to be released at all. These indicators included those related to inflation and employment—among the latter, the creation of non-farm jobs and the level of unemployment. The lack of visibility confounded investors and the Fed, as it was not clear whether-or-not interest rates needed to be cut further. On December 10th, less than a month after the shutdown ended and with still incomplete economic data, the Fed reduced the policy rate by 25 basis points in the absence of strong inflation pressures and the appearance of a softening economy. The dollar depreciated vs. practically all the currencies in our region of operations in the quarter except for the Brazilian real and the Argentinean peso, declining 2.3% vs. the Mexican peso; 3.7% vs. the Colombian peso and 5.7% vs. de Chilean peso and remaining practically flat vs. the Euro.

Fourth quarter revenue rose 3.4% in Mexican peso terms from a year ago, to 245 billion Mexican pesos. They were up 6.2% at constant exchange rates, with service revenue expanding 5.3%. The difference between the rate of growth in nominal terms vs. that at constant exchange rates mainly reflects the 9.6% appreciation relative to the year-earlier quarter of the Mexican peso vs. the U.S. dollar.

The apparent decelaration of service revenue growth—which extends to most revenue categories—stems from the incorporation of our Chilean operation from November 2024.

Mobile service revenue growth remained strong at 6.2% supported by postpaid revenue that was up 7.6%. Prepaid revenue growth maintained the pace seen the prior quarter, the fastest in at least five quarters, with that coming from Mexico accelerating from 2.8% to 3.8%.

Fixed-line service revenue was up 3.6% year-over-year. Mexico improved, moving from a 1.4% contraction in the third quarter to 2.2% growth, and Eastern Europe also accelerated. Corporate networks revenue strengthened and reached 6.9%. Mexico, Brazil and Austria drove this improvement, with Mexico reversing the decline of the previous quarter to grow 4.7%. Fixed-broadband revenue increased 6.4%. Mexico performed well, with broadband revenue rising from 2.0% to 3.9%.

EBITDA was up 4.2% in Mexican peso terms to 94.9 billion pesos and 6.9% at constant exchange rates from the year-earlier quarter, with the EBITDA margin improving slightly to 38.8%.

Our operating profit totaled 49.1 billion Mexican pesos, up 5.9% in nominal terms and 8.3% at constant exchange rates, while our comprehensive financing costs were roughly half those of the year-earlier quarter. This resulted in a net profit of 19.1 billion Mexican pesos in the quarter, four times larger than that of a year before. It was equivalent to 32 Mexican pesos cents per share or 35 dollars cents per ADR.

Our operating cash flow for the year 2025 came in at 212.7 billion pesos after deducting from our EBITDAaL (EBITDA after leases) a 16.4 billion pesos increase in working capital and 81.8 billion pesos in interest payments and taxes. After capital expenditures in the amount of 130.8 billion pesos we were left with a free cash flow of 81.9 billion pesos. The latter figure represents a 39.4% year-on-year increase in our free cash flow.

Shareholder distributions reached 45.1 billion pesos—including 11.9 billion pesos in share buybacks— even as we reduced our net debt in cash flow terms by 20.0 billion pesos. At the end of the year our net debt to LTM EBITDAaL ratio stood at 1.52 times.

644k postpaid net adds

We posted net additions of 264 thousand wireless subscribers during the quarter with postpaid net adds coming in at 644 thousand clients. Claro delivered a strong performance in the Pay TV segment, with 42 thousand net additions. In addition, we registered 113 thousand new broadband subscribers. Altogether, fixed-line RGUs reached 21.9 million.

Service revenue +5.1% YoY

Revenue increased 6.3% year-over-year, with service revenue up 5.1%, consistent with the pace observed in the previous quarter. In the wireless segment, service revenue grew 7.6% annually, driven by an 8.5% expansion in postpaid revenue and a 3.7% increase in prepaid revenue. Wireless performance reflects the continued expansion of the postpaid base, rising ARPU levels, and sustained consumer preference as evidenced by positive number portability trends. In the fixed-line division, service revenue growth accelerated from 1.4% in the third quarter to 1.8% in the current period, supported by a 5.8% year-over-year increase in corporate network revenue and a 3.5% rise in broadband revenue.

EBITDA +6.8% YoY

EBITDA for the period rose 6.8% to 5.9 billion reais. The EBITDA margin stood at 44.0%, expanding 20 basis points relative to the year-earlier-quarter.

In December 2025, an agreement was signed formalizing the adaptation of the contracts governing the concession of long-distance switched fixed-telephony services to the authorization regime. Upon completion of this process: (i) the assets used for the provision of the aforementioned services were no longer considered reversible and became free of encumbrances or restrictions; (ii) long-term investment and maintenance commitments were established; and (iii) certain disputes related to the concession were extinguished. Overall, the new framework provides greater regulatory flexibility, reduces legacy obligations, and strengthens Claro’s long-term investment environment.

500k wireless net adds

Wireless net additions came in strong in the fourth quarter at 500 thousand subscribers, of which over half were postpaid subs. We ended December with 42.7 million wireless clients, 4.2% more than at the end of 2024. In the fixed-line segment we connected 49 thousand broadband accesses but disconnected 42 thousand land-lines and PayTV units for a net of seven thousand fixed-line RGUs.

Wireless service revenue +7.6% YoY

Total revenue reached 4.3 trillion Colombian pesos in the quarter with service revenue rising 5.4%. Mobile service revenue was up 7.6% year-on-year with postpaid revenue growth accelerating to 7.8%. In the fixed-line segment we saw service revenue rising 2.2% on the back of 16.1% broadband revenue growth that offset the decline in fixed-voice and PayTV revenue.

EBITDA +4.1% YoY

Great operating leverage and cost discipline drove a solid increase in EBITDA. Reported EBITDA rose 4.1% year-on-year, while organic EBITDA expanded 6.3%, as the comparison was affected by extraordinary items and provisions recognized in both periods. Our EBITDA margin reached 41.0%, an increase of 2.2 percentage points over the last twelve months.

148k postpaid net adds

We added 148 thousand postpaid clients in the fourth quarter but disconnected 194 thousand prepaid users, resulting in a net reduction of 47 thousand subscribers in the period.

Total RGUs reached over two million units, 3.0% more than a year before.

Service revenue +4.0% YoY

Fourth-quarter revenue reached 1.8 billion soles, 7.2% higher than a year before. This increase reflects service-revenue growth of 4.0% and a rebound in equipment revenue of 18.1% year-on-year. In the mobile segment, service revenue rose 4.1%, supported by an acceleration in postpaid revenue, which increased from 4.8% in the third quarter to 5.4% in the current period, driven by robust subscriber additions. Fixed-line service revenue increased 3.4%. Broadband revenue—our main fixed-line revenue stream—was 2.7% higher than a year earlier, consistent with growth in previous quarters; while PayTV accelerated to 6.6% following a 1.4% increase in the preceding quarter.

17k new broadband accesses

We added 15 thousand postpaid subscribers during the quarter but disconnected 41 thousand prepaid subscribers, resulting in a net loss of 25 thousand subscribers. The wireless base ended December with 9.7 million subscribers. In the fixed-line division we recorded net additions of 38 thousand RGUs, including 17 thousand new broadband accesses. Total fixed-line RGUs reached 771 thousand by year end, representing a 29.2% increase compared with the close of 2024.

Fixed-line service revenue +8.5% YoY

Fourth quarter revenue totaling 271 million dollars was down 1.2% year-over-year, reflecting a 1.7% decrease in service revenue. Wireless service revenue fell 3.0% year-over-year driven by a 7.3% contraction in prepaid revenue. The annual comparison is affected by an extraordinary increase in prepaid revenue recorded in the fourth quarter of last year on account of higher usage during nationwide power outages, when customers were temporarily unable to access fixed broadband services. We continued to expand the coverage of our fiber network, allowing fixed-line service revenue growth to accelerate from 7.2% in the third quarter to 8.5% in the current period. Broadband and Pay TV revenue growth came in at 16.8% and 11.2%, respectively.

EBITDA +5.3% YoY

EBITDA increased 5.3% year-over-year to 140 million dollars; it was equivalent to 51.6% of revenue. The EBITDA margin expanded 3.2 percentage points from the year before.

Launch of 5G networks

We successfully renewed our concession in Ecuador for a 15-year term. As part of this process, Claro was granted the use of additional spectrum for the deployment of 5G in the 3.5 GHz and 700 MHz bands. Thanks to this, in December we launched 5G services in the main cities across all regions of the country. Today, we operate the first 5G network in Ecuador, enabling our customers to enjoy higher speeds, lower latency, and improved service quality. We will continue expanding the footprint of our 5G infrastructure to support the country’s technological and productive development.

307k wireless net adds & 57k new broadband accesses

We added 307 thousand wireless subscribers during the period, of which 81 thousand were postpaid clients. We ended December with 27.4 million wireless subscribers, representing an annual increase of 5.7%. Fixed-line additions totaled 123 thousand, including 57 thousand broadband accesses. Total fixed-line RGUs reached 4.1 million at the end of 2025, 11.9% higher than a year earlier.

Service revenue +10.1% YoY

Revenue for the quarter totaled 770.7 billion Argentine pesos, up 7.4% year-over-year in after-inflation terms. Service revenue increased 10.1% annually driven by wireless service revenue growth of 10.8%. Postpaid revenue growth accelerated from 3.7% in the third quarter to 8.3% in the current period, while prepaid revenue growth moderated to 18.6%, down from 43.7% in the third quarter. Fixed-line service revenue rose 7.6% year-over-year, compared with 11.8% in the previous quarter, as competition intensified, particularly in broadband services.

EBITDA +15.1% YoY

Inflation continued to decelerate in the fourth quarter, confirming the disinflation trend observed throughout the year. While monthly price increases picked up modestly toward year-end, reflecting seasonal effects and relative price adjustments, full-year inflation closed at 31.5%, the lowest level in eight years. At the same time, strict cost controls supported EBITDA growth of 15.1% year-over-year. EBITDA margin reached 42.7% of revenue, 2.8 percentage points higher than the year-earlier quarter.

Mobile service revenue rose 2.7%, rebounding after a slight decline in the prior period. Fixed-line service revenue increased 2.1%, driven by growth in corporate network and broadband revenue, which rose 17.5% and 7.0%, respectively. EBITDA increased 4.6%, with the EBITDA margin expanding by 89 basis points to 52.7%.

Austria and Eastern Europe

29k mobile net adds in Austria

Our combined wireless subscriber base in Europe reached 30.2 million at the end of December, following net additions of 890 thousand subscribers. These included one million M2M units from A1 Digital, 29 thousand additions in Austria, and net disconnections of 176 thousand subscribers in Eastern Europe, all of which were prepaid. In the fixed-line segment RGUs increased by 48 thousand, ending the year with 6.5 million RGUs.

Service revenue +1.7% YoY

Revenue for the Group totaled 1.5 billion Euros, a 1.1% increase compared with the prior year. Service revenue was up 1.7%, accelerating from 0.7% in the previous quarter. Growth accelerated in both the mobile and fixed-line segments: mobile service revenue growth increased from 1.1% in the third quarter to 2.0% in the current period, while fixed-line service revenue rose 1.5%, up from near zero in the prior quarter. This acceleration was driven primarily by improved trends in Eastern Europe.

EBITDA +7.4% YoY, excluding one-offs

EBITDA declined 2.7% year-over-year to 502 million Euros. It is worth noting that the annual comparison is affected by extraordinary items, which include 17 million euros in legal provisions recorded in the current period and 33 million euros in extraordinary items in the fourth quarter of last year. Excluding these effects, EBITDA increased 7.4% year-over-year. The EBITDA margin for the quarter stood at 33.6% of revenue.

5G spectrum in Serbia

In November 2025, A1 Serbia secured 5G spectrum in several key bands for a total of 100 million euros. Following license issuance in early December, the company immediately began deploying 5G networks.

The following table reconciles net cash flows provided by operating activities (an IFRS measure) to free cash flow (a non-IFRS measure). Our management defines free cash flow as funds from operations less capital expenditures. Funds from operations are calculated by subtracting payments of lease liabilities and net interest paid, and adding employee benefits, investing activities and others to net cash flows from operating activities.

Net cash flows from operating activities (IFRS measure)	272,399	239,341

(-) Capital Expenditures	-130,817	-130,835
Free Cash Flow (non-IFRS measure)	81,884	58,730

Free cash flow is presented as a supplemental non-IFRS measure because management believes that it provides additional perspective and useful insight into the Company’s ability to generate cash after excluding the adjusted items, including necessary capital expenditures. This non-IFRS measure should not be considered superior to, a substitute for or an alternative to, and should be considered in conjunction with the IFRS measure presented herein.
