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.

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.

Colombia

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.

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.

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.

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.
