Insights

Telecom equity analyst

Solid quarter: higher service growth, big FCF, lower leverage.

América Móvil delivered balanced top-line and margin performance. Total revenue reached Mex$232.9B (up 4.2% in pesos; 6.2% constant), while service revenue matched the 6.2% constant rate. EBITDA was Mex$93.8B (up 4.9%) with a 40.3% margin, reflecting stable profitability despite mixed fixed-line trends.

Earnings benefited from financing dynamics: comprehensive financing cost declined, lifting net income to Mex$22.7B (EPS Mex$0.38; ADR US$0.40). Cash generation was strong with nine‑month free cash flow of Mex$53.0B (up 47.0%), after Mex$84.9B capex, supporting balance sheet progress.

Leverage improved to 1.55x Net Debt/LTM EBITDAaL. A new €650M 5‑year bond at a 3% coupon funds euro CP repayment, smoothing maturities. Commercial momentum included 3.1M postpaid net adds and 526k broadband; future segment trends will be seen in subsequent disclosures.

Mexico City - América Móvil, S.A.B. de C.V. (“América Móvil”) [BMV: AMX] [NYSE: AMX, AMOV], announced today its financial and operating results for the third quarter of 2025.

• We added just over three million postpaid clients in the third quarter with Brazil contributing 1.5 million, followed by Colombia with 251 thousand, Peru with 198 thousand; and Mexico with 98 thousand. On the prepaid platform we recorded net disconnections of 31 thousand, resulting from losses in Brazil, Ecuador and Chile, which offset net subscriber additions obtained in several countries including Argentina 253 thousand, Colombia 237 thousand, and Mexico 136 thousand.

• In the fixed-line segment we gained 526 thousand broadband accesses, including 211 thousand in Mexico, 86 thousand in Brazil, 56 thousand in Argentina and 51 thousand in Colombia.

• Third quarter revenues totaled 232.9 billion Mexican pesos. They were up 4.2% in Mexican peso terms and 6.2% at constant exchange rates, with service revenue also expanding at the 6.2% pace.

• Mobile service revenue growth accelerated to a 7.1% pace at constant exchange rates on the back of stronger prepaid revenue growth: 3.9% vs. 3.1% in the second quarter. Postpaid revenue climbed 9.1%.

• On the fixed-line platform service revenue increased 4.7% at constant exchange rates having decelerated on account of a reduction in the rate of growth of corporate networks revenue.

• EBITDA totaled 93.8 billion Mexican pesos and was up 4.9% in Mexican peso terms and 6.8% at constant exchange rates from the year-earlier quarter—adjusting for tower sales a year ago—, with the EBITDA margin remaining practically unchanged at 40.3%.

• Our operating profit came in at 50.1 billion Mexican pesos and was up 5.6% in nominal terms and 6.4% at constant exchange rates. With our comprehensive financing costs roughly cut in half compared to those of the year-earlier quarter, our net income totaled 22.7 billion Mexican pesos.

• In the nine months to September our free cash flow allowed us to cover 28.6 billion pesos of shareholders distributions—including 10.8 billion pesos in share buybacks— increase our equity investments by 1.0 billion pesos; fund 10.0 billion pesos of the labor obligation amount due this year; and reduce our net debt by 15.7 billion pesos.

• At the end of September our net debt (excluding leases) stood at 454 billion pesos and was equivalent to 1.55 times Net Debt/LTM EBITDAaL.

EUR 650M bond with a 3% coupon

After a six year absence we returned to the euro market on September 24th with a 5-year 650 million euro bond with a 3% coupon. The yield on the bond was 68 basis points above the mid-swaps reference point, making it the second tightest spread achieved by a telecom company in the five-year tenor over the last two years. The proceeds will be directed to the payment of short term debt under our Euro commercial paper program.

Access Lines

3.1M postpaid net adds

We added just over three million postpaid clients in the third quarter with Brazil contributing 1.5 million, followed by Colombia with 251 thousand, Peru with 198 thousand, and Mexico with 98 thousand. On the prepaid platform we recorded net disconnections of 31 thousand, resulting from losses in Brazil, Ecuador and Chile, which offset net subscriber additions obtained in several countries including Argentina 253 thousand, Colombia 237 thousand, and Mexico 136 thousand.

526k new broadband accesses

In the fixed-line segment we gained 526 thousand broadband accesses, including 211 thousand in Mexico, 86 thousand in Brazil, 56 thousand in Argentina and 51 thousand in Colombia. Meanwhile, voice lines and PayTV units declined by 82 thousand and 48 thousand, respectively, during the quarter. At the end of September we had 407.6 million accesses of which 140 million were postpaid clients and 79 million fixed-line RGUs. Year-over-year our postpaid base increased 8.1% and broadband accesses 5.1%.

América Móvil Consolidated Results

In the third quarter, with the U.S. economy finally appearing to slow down as evidenced by a sharp decline in the number of new jobs created, the Fed went ahead with the much-anticipated reduction in its policy interest rate, which was brought down by 25 basis points in September. Since mid-July long term interest rates had been on a downward trend with ten-year rates falling from nearly 4.5% to 4.1% at the end of the quarter. With lower interest rates and the expectation of further interest rate cuts by the Fed, the U.S. dollar lost ground vs. practically all currencies in our region of operations, declining -2.7% vs. the Mexican peso; -2.5% vs. the Brazilian real and -4.1% vs. the Colombian peso. The dollar remained practically flat vs. the euro with the Argentine peso the only major exception in the period that depreciated vs. the dollar.

Third quarter revenues totaled 232.9 billion Mexican pesos. They were up 4.2% in Mexican peso terms and 6.2% at constant exchange rates, with service revenue also expanding at the 6.2% pace. The difference between the rate of growth in nominal terms vs. that at constant exchange rates mainly reflects the appreciation of the Mexican peso vs. the U.S. dollar, the Chilean peso and the Argentine peso as the former remained practically flat vs. the Brazilian real and the Colombian peso.

On the mobile platform service revenue posted its best rate of growth in over a year, 7.1%, helped along by the continued recovery of prepaid revenue. The latter expanded 3.9%, the fastest pace in two years, while postpaid revenue climbed 9.1%, very similar pace to that of the precedent quarter, which was the quickest one in ten quarters. Mexico, Colombia and Chile were the main operations behind the acceleration of mobile service revenue growth.

As for fixed-line service revenue, it decelerated to 4.7% from 7.9% the prior quarter. This deceleration has to do with the significant slowdown registered in corporate networks revenue, which fell from a 15.0% increase in the second quarter to a 3.5% increase in the third. Corporate networks revenue tends to be more volatile as it is associated with the pipeline of corporate networks contracts and IT projects. We are an increasingly relevant player in this business segment which is an ever more important revenue item for us: its share of fixed-line service revenue has reached 21%.

EBITDA totaled 93.8 billion Mexican pesos and was up 4.9% in Mexican peso terms and 6.8% at constant exchange rates from the year-earlier quarter— adjusting for tower sales a year ago— with the EBITDA margin remaining practically unchanged at 40.3%.

Our operating profit came in at 50.1 billion Mexican pesos and was up 5.6% in nominal terms and 6.4% at constant exchange rates. With our comprehensive financing costs roughly cut in half compared to those of the year-earlier quarter our net income surged to 22.7 billion Mexican pesos. It was equivalent to 38 Mexican pesos cents per share or 40 dollars cents per ADR.

We ended up with 137.9 billion pesos in operating cash flow in the nine months to September after deducting from our EBITDAaL (EBITDA after leases) 33.5 billion in increased working capital and 66.9 billion pesos for interest payments and taxes in the period. Since capital expenditures totaled 84.9 billion pesos over that period, our free cash flow amounted to 53.0 billion pesos, compared to 36.1 billion pesos in the same period of the preceding year, a 47.0% year-on-year increase.

The former amount plus 2.3 billion pesos in dividend income allowed us to distribute 28.6 billion pesos to our shareholders—including 10.8 billion pesos in share buybacks— increase our equity investments by 1.0 billion pesos; pay out 10.0 billion pesos of our labor obligations due this year; and reduce our net debt by 15.7 billion pesos.

At the end of September our net debt stood at 454 billion pesos and was equivalent to 1.55 times Net Debt/LTM EBITDAaL.

98k postpaid gains and 211k new broadband accesses

We added 235 thousand wireless subscribers in the third quarter, including 98 thousand postpaid clients and 136 thousand prepaid subs. Our wireless subscriber base ended September with 84.3 million clients, as the postpaid base expanded 3.1% year-on-year. On the fixed-line platform we gained 218 thousand clients, substantially all of them broadband clients, closing the quarter with 22.5 million RGUs, 3.3% more than a year before.

Mobile service revenue +4.9% YoY

Third quarter revenues were up 2.0% year-on-year to 85.5 billion Mexican pesos with service revenue expanding 2.9%. On the mobile platform service revenue accelerated to 4.9%—its best showing since the first quarter of 2024, whereas on the fixed-line platform service revenue declined 1.4%.

Signs of recovery on the prepaid platform, +2.8% YoY

The acceleration of mobile service revenue growth was driven by the continued improvement in prepaid revenue growth that increased 2.8% compared to 1.2% in the prior quarter—its fastest growth in four quarters. Postpaid revenue growth remained at 7.8% year-on-year, the fastest rate of growth in ten quarters.

Broadband revenue 2.0% YoY

On the fixed-line platform broadband revenue growth slowed to 2.0%, down from 3.6% in the previous quarter, while corporate networks revenue declined 5.8% after a 10.8% increase in the second quarter. Revenue from corporate networks tends to be volatile, as it is often influenced by the timing and scale of special IT projects and enterprise contracts.

Adjusted EBITDA +1.4% YoY

Adjusting for tower sales a year ago, EBITDA was up 1.4% to 35.4 billion pesos, accounting for a 41.4% EBITDA margin.

251k postpaid net adds

During the third quarter, we added 488 thousand mobile subscribers in Colombia, including 251 thousand postpaid subscribers. This segment has shown improving trends for seven consecutive quarters, driven by Claro’s leadership in 5G.

Mobile service revenue +7.8% YoY, fastest pace in five years

Total revenues rose 5.9% year-over-year to 4.1 trillion Colombian pesos, with service revenues increasing 5.6%, supported by strong mobile service revenue growth of 7.8%—the fastest pace in five years. Fixed-line service revenue grew 2.4%.

EBITDA +3.0% YoY

EBITDA increased 3.0% to 1.7 trillion Colombian pesos and the EBITDA margin came in at 41.0% due to additional provisions booked in the third quarter related to litigation processes that initated in the second quarter; adjusting for these, EBITDA would have increased by 5.1% annually and the margin would have been equivalent to 41.9% of revenue.

198k postpaid net adds

Net subscriber additions reached 274 thousand in the third quarter with 198 thousand postpaid additions and 77 thousand prepaid gains, reversing the negative trend of prepaid disconnections observed since the fourth quarter of 2024. Our wireless subscriber base ended September at 13.1 million, up 2.3% year-over-year. On the fixed-line side, we connected 37 thousand new RGUs—23 thousand of which were broadband accesses—bringing the total base to just under two million units.

Mobile service revenue +4.9% YoY

Revenue rose 3.1% year-over-year to 1.7 billion soles. Service revenue increased 4.6%, with mobile service revenue expanding 4.9% and fixed-line service revenue accelerating to a 3.9% pace from 1.3% the previous quarter. Growth was particularly strong in the corporate segment supported by IT solutions.

EBITDA +9.2% YoY

We posted solid EBITDA growth of 9.2% year-over-year, with EBITDA reaching 699 million soles. This represented an EBITDA margin of 40.1%, up from 37.9% in the same period a year before. Third quarter EBITDA reflects a positive one-off effect derived from tower sales of 5.9 million soles.

Additional spectrum for 5G

In September, we were granted the use of 100 MHz of spectrum in the 3.5 GHz band, which will be instrumental for the operation of our 5G network, that today covers 12 major cities. This additional spectrum will allow Claro to increase its coverage, network speed and overall customer experience.

25k new broadband accesses

Our wireless subscriber base ended September with 9.7 million subscribers following net disconnections of 320 thousand in the third quarter, all in the prepaid segment. On the fixed-line side we connected 61 thousand new RGUs—25 thousand of which were broadband accesses— bringing the total to 733 thousand units.

Fixed-line service revenue +7.2% YoY

Revenues totaled 257 million dollars, rising 1.6% year-on-year as did service revenue, which experienced an important acceleration relative to the 0.1% pace observed the previous quarter. The improvement in service revenue growth originated on both platforms: on the mobile one service revenue rebounded from -0.4% in the prior quarter to 0.9% in the current period, driven by postpaid revenue; in the fixed-line segment service revenue growth reached 7.2%, up from 4.1% the previous quarter, on the back of strong broadband revenue growth, 9.2%, doubling the growth rate observed in the prior quarter.

EBITDA +3.8% YoY

EBITDA came in at 129 million dollars, up 3.8% year-over-year, which compares to the 2.0% increment seen the previous quarter. The EBITDA margin stood at 50.1% and was 90 basis points higher than a year before.

Argentina economy recovery

Argentina’s economy continued to recover in the third quarter, with GDP growing 8.5% year-over-year driven by strong private consumption and investment. Inflation eased to 1.9% monthly by August. Following the elections in the province of Buenos Aires the peso traded near the upper end of its managed band, prompting swift action from the Central Bank to preserve stability and investor confidence.

Service revenue +11.9% YoY

Claro’s revenue increased 7.0% year-over-year in after-inflation terms with service revenue rising 11.9%. Mobile service revenue rose 12.0%, led by a strong performance in the prepaid segment. Postpaid revenue growth accelerated from 0.6% in the prior quarter to 3.7% in the current period. Fixed-line service revenue rose 11.8%, supported by solid growth in PayTV and broadband services.

EBITDA +11.7% YoY

EBITDA increased 11.7% to 286 billion pesos, equivalent to 41.2% of revenue. The EBITDA margin improved by 1.7 percentage points compared to the same period last year.

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.

	Millions of Mexican pesos
		Jan-Sep 25	Jan-Sep 24
	Net cash flows from operating activities (IFRS measure)	186,665	158,072
	(-) Payments of lease liabilities	-38,710	-33,422
	(-) Net interest paid	-27,488	-25,150
	(+) Employee benefits	10,025	23,733
	(+) Investing activities (Derivative instruments, other investments) and others	7,370	-441
	Funds from Operations	137,862	122,792
	(-) Capital Expenditures	-84,870	-86,737
	Free Cash Flow (non-IFRS measure)	52,992	36,055

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.
