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 first quarter of 2025.

| • |  | In the first quarter we added 2.4 million postpaid subs with Brazil leading the way with 987 thousand followed by Colombia with 163 thousand and Mexico with 133 thousand. In the prepaid segment we disconnected 1.0 million subs as Mexico and Brazil reported losses.

| • |  | In the fixed-line segment we connected 446 thousand broadband accesses. Mexico gained 165 thousand clients, followed by Brazil with 98 thousand and Central America with 52 thousand.

| • |  | First quarter revenue was up 14.1% year-on-year in Mexican peso terms to 232 billion pesos, with service revenue expanding 15.8% and adjusted EBITDA 13.3%. At constant exchange rates service revenue increased 6.1% and adjusted EBITDA 4.0%.

| • |  | Mobile service revenue was up 5.7%, on the back of 8.8% postpaid revenue growth. On the fixed-line platform service revenue increased 6.7% at constant exchange rates. Broadband revenue grew 9.8% while PayTV rose 8.7%, the fastest pace seen in many quarters.

| • |  | Operating profit totaled 44.8 billion pesos, up 10.0% year-on-year after depreciation and amortization charges that rose 16.1%, partly reflecting the incorporation of our Chilean operation.

| • |  | Net income was up 38.6% to 18.7 billion pesos reflecting both the increase in our operating profit and a slight decrease in our comprehensive financing costs from the year-earlier quarter.

| • |  | Net financing of 10.9 billion pesos, coupled with our operating cash flow, allowed us to cover 24.7 billion pesos in CapEx, 3.8 billion pesos in share buybacks and 7.0 billion pesos in labor obligations.

| • |  | At the end of March, our net debt—excluding leases—stood at 500 billion pesos, and represented a net debt-to-EBITDAaL ratio of 1.50 times.

The reported figures for Argentina corresponding to the first quarter of 2025 are presented in accordance with IAS29 reflecting the effects of inflationary accounting as the Argentinean economy is deemed to be hyperinflationary. All comparisons at constant exchange rates for América Móvil’s consolidated figures will exclude Argentina to ensure consistency.

América Móvil Consolidated Results

The first quarter of the year began with interest rates surging ahead continuing their trend from early December, as the markets grew increasingly concerned with inflation on signs of a much stronger economy than had been expected. However, as inflation numbers came in within expectations and new payroll figures weakened, U.S. 10-year Treasury yields came down by a remarkable 60 basis points from mid-January to end the quarter at 4.20%. In the period most currencies in our region of operations appreciated vs. the U.S. dollar, but not the Mexican peso, which remained almost flat over the quarter as the uncertainty over potential new tariffs by the U.S. weighed on it. In the quarter, the US dollar lost 7.3% vs the Brazilian real, 4.9% vs the Colombian peso, 4.4% vs the Chilean peso and 4.2% vs the euro.

Our first quarter revenue was up 14.1% year-on-year in Mexican peso terms to 232 billion pesos, with service revenue expanding 15.8% and adjusted EBITDA 13.3%. The latter figures partly reflect the year-over-year appreciation of most currencies vs the Mexican peso, particularly the Colombian and Chilean pesos, up 18.0% and 14.0%, respectively; the dollar at 17.7% and the euro at 14.1%. At constant exchange rates service revenue increased 6.1% and EBITDA 3.7% before one-off adjustments, or 4.0% after the adjustments are made. Most of our operations saw their EBITDA margins increase sequentially.

Wireless service revenue climbed 5.7%, decelerating somewhat from the prior quarter, as prepaid revenue continued to slow down mostly on account of weaker economic activity in Mexico. Postpaid revenue growth remained fairly stable across the board and actually accelerated slightly to 8.8% when our Chilean operation is included.

On the fixed-line platform service revenue growth came in at 6.7% with corporate networks revenue appearing to slow down. This effect had mostly to do with the fact that in the year-earlier quarter that line item had had a very strong showing. Broadband revenue growth maintained its pace at 9.8% while that of PayTV came in at 8.7%, the fastest pace seen in many quarters.

The Central America and the Eastern European blocks were top performers in the period, exhibiting faster service revenue growth in both the fixed and the wireless platforms than they had had the preceding quarter.

Our first quarter operating profit totaled 44.8 billion pesos, a 10.0% year-on-year increase after depreciation and amortization charges that were up 16.1%, which partly reflects the incorporation of our Chilean operation.

With our comprehensive financing costs decreasing slightly from the year-earlier quarter our net income was up 38.6% to 18.7 billion pesos and was equivalent to 31 pesos cents per share and 30 dollar cents per ADR.

Our net debt stood at 500 billion pesos at the end of March not including capitalized lease obligations. It was equivalent to 1.50 LTM EBITDA. In cash flow terms it increased 10.9 billion pesos in the quarter, helping us fund capital expenditures in the amount of 24.7 billion pesos, share buybacks of 3.8 billion pesos and 7.0 billion pesos in labor obligations.

Mexico

133k postpaid net adds & 165k new broadband accesses

In the first quarter we gained 133 thousand postpaid subscribers and disconnected 821 thousand prepaids, the latter a reflection of the economic slowdown in the country that has been observed over the last several months. Altogether we had 83.9 million wireless subscribers at the end of the quarter. According to figures published by IFT, our market share at the end of December was 54.7%.

Broadband net additions came in strong at 165 thousand. Our fixed-line base reached 22.1 million RGUs. Telmex is set to maintain its prices and remains highly competitive in its commercial offers featuring high-speed internet and attractive content packages. At the end of December, Telmex’s broadband market share was 40%.

Service revenue +1.0% YoY; broadband revenue +6.9% YoY

Revenue totaled 82.1 billion Mexican pesos in the period, a 2.3% decline over the year-earlier quarter brought about by a 14.3% reduction in equipment sales. Service revenue was up 1.0% with mobile revenue increasing 0.8% and fixed-line service revenue rising 1.5%. Broadband revenue expanded 6.9%, its best performance in three quarters. However, the growth rate for fixed-line service revenue is affected by certain corporate networks projects registered in the year-earlier quarter. On the mobile front postpaid revenue growth was stable at 5.5%, while prepaid revenue declined 2.5% over the prior year, very much resulting from the economic deceleration in the country as ARPU declined 2.2%.

EBITDA margin at 41.9%

EBITDA came in at 34.4 billion pesos and was down -2.8% after one-offs. In addition to these adjustments it is important to note that the booking of certain IT projects a year ago mentioned above had an impact on the EBITDA for the period which observed then an 11.0% year-on-year increase. The EBITDA margin, 41.9%, was up sequentially, from 41.3%.

Brazil

987k postpaid net adds & 98k new broadband accesses

We added 987 thousand postpaid subscribers in the first quarter and disconnected 545 thousand prepaid subs, with our wireless subscriber base reaching 87.6 million subscribers at the end of March. On the fixed-line platform RGUs were down 125 thousand in the period on less land-lines and PayTV accesses; broadband acceses were up 98 thousand.

Mobile service revenue +8.8% YoY

Revenue rose 6.2% year-on-year to 12.5 billion reais, with service revenue up 6.0% on the back of 8.8% mobile revenue growth, as postpaid revenue expanded 11.5% and prepaid revenue declined 2.6%. On the fixed-line platform service revenue climbed 2.6% with PayTV revenue down 3.1%—its smallest rate of decline in at least a year—and broadband revenue decelerating to 5.1%. Although it represents only 11.4% of service revenue, corporate networks revenue had an important contribution, as it surged 16.4% from the year-earlier quarter.

EBITDA +8.1% YoY

EBITDA came in at 5.5 billion reais, an 8.1% increase, with the EBITDA margin reaching 44.1% on greater operating leverage and strong cost controls.

Colombia

297k wireless net adds

We added 297 thousand mobile subscribers in the quarter—including 163 thousand postpaids—to reach a total of 41.3 million wireless subs, 3.8% more than a year before. Our fixed-line base reached 9.6 million after gaining new RGUs in all services: 20 thousand landlines, 15 thousand broadband accesses and seven thousand PayTV units.

Mobile service revenue +6.0% YoY

Revenue topped four trillion Colombian pesos in the first quarter, 5.9% more than a year before, following service revenue growth of 3.4% and equipment revenue growth of 16.1%. These figures point to the continued strengthening of our mobile operation, which showed service revenue growth of 6.0%—the fifth quarter with sequential improvements—and further engagement of clients through handset sales. The acceleration stems mostly from the postpaid segment, as we have been upselling clients to better value plans on the back of our expanded 5G footprint, now covering 20 cities.

In the fixed-line segment service revenue was down 0.3% year-on-year, bogged down by broadband revenue that declined 2.3%. The annual comparison of this business line is affected by extraordinary revenue booked in the first quarter of 2024 related to an adjustment in a government contract to provide internet services in rural areas. Correcting for this, broadband revenue increased by 7.7%, which in turn resulted in 3.1% service revenue growth.

EBITDA +2.4% YoY

EBITDA was up by 2.4% year-over-year to 1.6 billion Colombian pesos, equivalent to a 39.5% EBITDA margin.

Peru

129k postpaid net adds

We finished March with 12.8 million wireless subscribers after 63 thousand net additions—129 thousand postpaid gains and disconnections of 66 thousand prepaid subs. In the fixed-line segment we gained 18 thousand broadband accesses and five thousand PayTV units but reduced by 41 thousand the number of land-lines. Fixed-line RGUs were just shy of two million at the end of the quarter.

Service revenue +4.5% YoY

First-quarter revenue totaled 1.7 billion soles, a 3.0% year-over-year increase, with service revenue up 4.5%. On the mobile platform, service revenue rose 5.8%. Postpaid revenue growth remained strong at 5.0%, while prepaid revenue showed more dynamism, rising 8.3% compared to the year-earlier quarter. In the fixed-line segment service revenue was up 0.6% annually, with corporate networks and broadband revenue growing 4.1% and 3.5%, respectively, compensating for the decline in PayTV and wireline revenue.

EBITDA +8.0% YoY

Operating leverage and cost reduction efforts resulted in EBITDA posting an 8.0% annual increase to 657 million soles, bringing the EBITDA margin to 39.7%, 1.8 percentage points higher than a year before.

Southern Cone

Altogether, our operations in the southern cone added 426 thousand wireless subscribers, including 266 thousand postpaid clients. At the end of March our wireless base stood at 35.5 million subs, 6.8% more than a year before. Fixed-line RGUs net additions came in at 56 thousand accesses bringing the base to 7.1 million, 4.1% higher than a year before.

Argentina

All comments for Argentina related to annual variations of the presented period refer to figures in constant peso terms, that is, adjusted for inflation in accordance to NIC 29.

Service revenue +33% YoY & EBITDA +35% YoY

Overall economic activity in Argentina has picked up from a year before, and consumer spending has shown resilience in the face of declining inflation rates. Favored by this environment, Claro’s revenue growth continued to speed up in Argentina, posting annual revenue expansion of 28.4% in after-inflation terms, up from 20.2% in the prior quarter. Service revenue soared 32.9%, with mobile service revenue rising 31.8% and fixed revenue increasing 37.3%.

On the mobile platform, prepaid service revenue nearly doubled on account of strong net additions and greater spending capacity. On postpaid, revenue growth accelerated from 15.8% to 18.9%. On the fixed-line platform we’ve seen an important acceleration of PayTV revenue that jumped 71.9%, although from a small base, while broadband revenue was up 50.9% as demand for fiber and high-speed connectivity remained strong.

EBITDA for the period surged 35.3%, with the EBITDA margin breaking above the 40% mark, two percentage points higher than that of the year-earlier quarter.

Chile, Paraguay & Uruguay

Mobile service revenue +5.6% YoY

Revenue for the block increased 2.3% year-on-year to 315 billion Chilean pesos equivalent. Service revenue fell 0.7% as the increase in mobile service revenue, 5.6%, failed to compensate for the decline in fixed-line revenue, 5.1%. The former came about from 6.0% postpaid revenue growth and 1.1% growth in the prepaid segment.

The combined EBITDA expanded 46.0% to 60.7 billion Chilean pesos as the margin for the period jumped 5.8 percentage points to 19.3% of revenue.
