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 fourth quarter of 2023.

| • |  | We added 3.9 million wireless subscribers in the quarter, including 2.7 million postpaid clients. Brazil contributed with 1.8 million new contract clients, while 329 thousand came from Austria, 124 thousand from Argentina and 109 thousand from Mexico.

For comparison purposes all the figures below exclude Argentina

| • |  | Fourth quarter revenue was down 2.5% year-on-year to 204.4 billion Mexican pesos, with service revenue nearly flat, -0.1% on account of the appreciation of the Mexican peso vs all other currencies in our region of operations. At constant exchange rates service revenue was up 3.7%.

| • |  | Fourth quarter EBITDA came in at 79.7 billion pesos, a 3.3% reduction in nominal peso terms. At constant exchange rates and adjusting for extraordinary items—more importantly the tower sales in Mexico and Peru in the fourth quarter of 2022—it rose 4.6%.

| • |  | Our operating profit totaled 42.3 billion pesos in the quarter. After comprehensive financing costs of 5.3 billion pesos and 7.3 billion pesos in foreign exchange gains, it resulted in a net profit of 26.4 billion pesos.

| • |  | Our cash flow figures include Argentina: Cash flow plus 21.1 billion pesos in net borrowings enabled us to cover capital expenditures in the amount of 156.3 billion pesos, shareholder distributions totaling 40.4 billion pesos and 11.8 billion pesos in labor obligations.

Note

Upon the establishment of the joint venture with Liberty Latin America in October 2022, Claro Chile became a discontinued operation. The financial statements presented in this report account for those operations as discontinued operations.

The reported figures for Argentina corresponding to the fourth quarter of 2023 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 fourth quarter of 2023 turned out to be an extremely volatile one, with interest rates surging in the first month of the quarter to record highs not seen in over 16 years. This was in continuing with the trend that began early in the third quarter as inflation pressures brought about new increases in reference rates by the Fed. The yield of ten-year Treasury notes, which had stood as low as 3.75% in mid-July, shot up to 5% in exactly three months. But then things turned: new inflation readings appeared to be softer and the Fed put out the message that no new action on reference rates was expected for at least the remainder of the year. A huge rally in interest rates followed, with the ten-year Treasury yield plummeting back to where it had been in mid-July.

With the extreme financial stress over, the dollar, which had been overbought throughout the period of stress, fell against most currencies in our region of operations: 7.4% vs. the Mexican peso, 6.3% vs. the Brazilian real, 12.1% vs. the Colombian peso, and 4.3% vs. the euro. A major exception was the Argentine peso, which had long been in a special situation of its own. As a new administration took over the Argentine government in December, a new economic framework calling for liberalization of economic policy brought about a major devaluation of the currency, with the peso losing nearly 60% of its value vis-á-vis the dollar in December alone.

Argentina has gone through a period of high inflation the last several years. Since 2019 it has been subject to the accounting guidelines applicable to hyper-inflationary countries, with all the accounting variables expressed in real terms at constant Argentine pesos. For consolidation purposes in our financial statements—with no other economy considered hyper inflationary—those Argentine figures expressed in constant Argentine peso terms at the prevailing prices at the end of the period must be converted into Mexican pesos at the exchange rate observed at the end of the period, per IFRS rules. Given the magnitude of the Argentine peso depreciation, the application of the above-mentioned norm generates unusual effects.

We have thus decided to present a version of our financial statements excluding Argentina for greater clarity. Since 2019 we had been excluding Argentina from the analysis of our revenue and EBITDA at constant exchange rates that was presented every quarter, but not from our consolidated financial statements. We will present separately our consolidated results including Argentina after the application of both IFRS 29 and the IFRS 21 norms. In the discussion that follows, all figures cited, whether in nominal terms or at constant exchange rates, will exclude Argentina.

Our fourth quarter revenue was down 2.5% year-on-year to 204.4 billion Mexican pesos, with service revenue nearly flat, -0.1%, on account of the Mexican peso having increased in value vis-á-vis all other currencies in our region of operations save for the Colombian peso: 12% vs. the dollar; 5.7% vs. the real; 8.8% vs. the Peruvian sol and 1.8% vs. the euro. Under other income we registered a 67.4% reduction mostly having to do with the booking of certain extraordinary items in the fourth quarter of 2022, in particular the sale of towers by Telmex and Claro Peru and the release of certain provisions in Puerto Rico.

At constant exchange rates service revenue was up 3.7% with mobile service revenue growing 4.2% and that from the fixed-line platform expanding 3.0%. Mobile revenue decelerated from the 4.8% pace seen the prior quarter whereas fixed-line revenue accelerated from the 2.2% rhythm of the third quarter. This is the fourth quarter in a row with growth in both the fixed-line and mobile platforms. For the full year 2023 it was the first one in three years with positive growth in both platforms.

Mobile service revenue growth remained stable in Mexico at 4.5% whereas in Brazil it slowed down from the prior quarter to 7.1%. In Central America mobile service revenue growth accelerated to 10.7%.

On the fixed-line platform service revenue expanded at a faster pace in Mexico and Colombia, going from 3.6% to 5.9% in Mexico and from 1.0% to 5.9% in the latter. They maintained their pace in Brazil and decelerated somewhat in Austria and Central America. Revenue from corporate networks led the way on the fixed-line platform, expanding 8.1% from the year-earlier quarter, followed closely by broadband revenue that posted a 6.6% increase. PayTV revenue declined slightly, 1.1%, its smallest decline in over a year.

Corporate networks revenue growth was strongest in Eastern Europe, 30.2%; Colombia, 21.6%; Ecuador, 19.5%; and Mexico and Peru, with slightly more than 14% each. In Central America it accelerated to 6.6%, having posted every quarter over the last year faster growth rates than the preceding one.

Fourth quarter EBITDA came in at 79.7 billion pesos, a 3.3% reduction in nominal peso terms. At constant exchange rates and adjusting for the extraordinary items mentioned above—i) the tower sales in Mexico and Peru, ii) the release of provisions in Puerto Rico and Ecuador that took place in the fourth quarter of 2022 and 2023, iii) the settlement in the price of Oi in the current period, and iv) the reversal of duties booked in Austria—it rose 4.6%. Our operating profit stood at 42.3 billion pesos, a 6.2% decrease from the year-earlier quarter. At constant exchange rates and adjusting for the extraordinary items mentioned before, it was up 4.6%.

Comprehensive financing costs of 5.3 billion pesos were 5.9% higher than those of a year before, with net interest costs increasing 8.2%. We obtained foreign exchange gains of 7.3 billion pesos mostly on account of the Mexican peso strengthening vis-à-vis the dollar.

We booked a 26.4 billion pesos net profit, 67.8% higher than the one obtained a year before. The net profit for the full year came in at 82.8 billion pesos, a 12.8% increase over that obtained in 2022.

When Argentina is included in our consolidated income statement the impact is as follows:

1) total revenue in the fourth quarter is reduced by 3.7 billion pesos, to 200.7 billion pesos, with net service revenue also reduced, by 2.9 billion pesos, as is EBITDA, by 1.4 billion pesos—with EBITDA adjusted down to 78.3 billion pesos. These changes have to do with the requirement under IAS21 to convert flows into the currency of the consolidating entity using the exchange rate at the end of the period, there having been a major devaluation of the Argentine peso towards the end of the fourth quarter, which significantly reduced the Mexican peso value of the Argentine revenue and EBITDA streams relative to what had been recorded prior to this depreciation. A detailed explanation is presented under appendix B.

2) Comprehensive financing costs go up by 10.3 billion pesos with the inclusion of Argentina, mostly reflecting foreign exchange losses of 8.1 billion pesos in the country arising from lease and supplier debt as well as intercompany obligations.

3) Our net profit including Argentina is consequently lower than without Argentina, declining from 26.4 billion pesos in the latter case to 18.1 billion pesos. This figure, our net income, is equivalent to 29 peso cents per share and 33 dollar cents per ADR.

Including Argentina, our net debt excluding leases stood at 385.4 billion pesos in December, with the outstanding net debt having increased by 3.9 billion pesos throughout the year. Cashflow-wise our net debt increased by 21.1 billion pesos throughout the year, helping cover—together with our operating cash flow—capital expenditures in the amount of 156.3 billion pesos, shareholder distributions totaling 40.4 billion pesos—including 14.3 billion in share buybacks—and 11.8 billion pesos in labor obligations.

Mexico

165k broadband net adds and 109k postpaid net gains

We added 417 thousand mobile subscribers in the fourth quarter, 109 thousand were postpaid clients, the highest figure in three years. On the fixed-line platform we gained 172 thousand RGUs, as broadband net adds shot up by 165 thousand, taking the total net adds for the year to 464 thousand.

Service revenue +4.9% YoY

Revenue was up slightly from the year-earlier quarter to 84.4 billion pesos, with service revenue expanding 4.9%, somewhat faster than the 4.3% pace observed the prior quarter. Sequentially service revenue growth remained roughly constant on the mobile platform at 4.5%, but it continued to accelerate on the fixed-line segment, to a 5.9% pace compared to the 3.6% one observed in the third quarter.

Broadband revenue +7.2% YoY

Fixed-line revenue was buoyed by that of corporate networks, up 14.1% year-on-year, with broadband revenue expanding 7.2%. It is of note that corporate network revenue already accounts for 26.8% of our fixed-line revenue. On the mobile platform prepaid revenue was the most dynamic business line, with revenue growing 5.2%. Other revenue was down 63% reflecting the sale of towers by Telmex a year ago.

Our EBITDA was off 2.5% because of the afore-mentioned tower effect. Adjusting for it, EBITDA rose 4.9%.

Brazil

1.8M postpaid net adds and 61k new broadband accesses

Net additions for the quarter came in at 1.9 million of which 1.8 million were postpaid subscribers, this figure includes 710 thousand machine-to-machine devices. Claro’s postpaid growth is the result of significant reduction in churn, acceleration of prepaid customer migrations and clear leadership in mobile number portability. On the fixed-line platform, we connected 61 thousand broadband accesses, but disconnected 105 thousand voice lines and 129 thousand PayTV subscriptions. Our wireless base ended the year just shy of 87 million subscribers, 4.4% more than at the end of 2022, and on the fixed-line segment we had 23.1 million RGUs.

Service revenue +3.8% YoY driven by mobile service +7.1% YoY

Total revenue expanded 5.0% year-on-year to 11.7 billion reais, with service revenue rising 3.8%. On the mobile platform service revenue was up 7.1% while fixed-line service revenue remained practically unchanged from a year before even in the face of 6.3% growth of fixed-line broadband revenue. The latter came about on account of an increased number of broadband accesses, but also of ARPU increases associated with our greater share of the ultrabroadband segment.

Adjusted EBITDA +7.3% YoY

The quarter’s EBITDA reached 5.1 billion reais including 162 million reais related to the settlement with Oi on the price of the mobile business acquired by Claro. Adjusting for this one-off effect, EBITDA would have risen 7.3% taking the EBITDA margin to 41.9%, 80 basis points higher than that of the year-earlier quarter.

Colombia

538k wireless net adds, with 456k prepaid net adds

We added 538 thousand mobile clients in the fourth quarter—83 thousand postpaids and 456 thousand prepaid subs—and finished the year with 39.2 million subs, 4.5% more than at the end of 2022. We also had 9.4 million fixed-line RGUs in Colombia after adding 27 thousand units, approximately half of which were broadband accesses.

Fixed-line service revenue accelerated to 5.9% YoY

Fourth quarter revenue was up 3.8% from a year before to 3.9 trillion Colombian pesos. Service revenue came in 0.9% above last year’s, improving slightly from 0.2% in the prior quarter. The sequential improvement stems from the fixed-line segment posting 5.9% revenue growth—compared to 1.0% in the third quarter—and mobile service revenue declining 2.3% in the face of competitive pressure and price promotions.

EBITDA margin at 41.8% of revenue

EBITDA of 1.6 trillion Colombian pesos remained practically flat relative to the year-earlier quarter, with the EBITDA margin at 41.8% of revenue.

Spectrum for 5G deployment

In December we were granted the use of 80MHz of spectrum in the 3.5GHz frequency which will allow Claro to deploy 5G technology in the country. In addition, we were granted the use of an extra 10MHz in the 2.5GHz band that will benefit the quality of our 4.5G service. We are committed to continue to improve customer experience by adopting the latest technologies to develop the fastest and most reliable network.

Peru

73k postpaid net adds

We gained 73 thousand new postpaid subscribers in the fourth quarter and disconnected ten thousand prepaids, with our subscriber base reaching 12.5 million subs at the end of December. On the fixed-line segment, we registered 34 thousand net disconnections of voice accesses with not much change in the other segments, ending the year with 1.9 million fixed-line RGUs.

Service revenue +3.0% YoY with fixed-line services +4.4% YoY

Revenue totaled 1.6 billion soles declining 9.2% year-on-year; the annual comparison is affected by the sale of towers that was booked in the fourth quarter of 2022. Service revenue was up 3.0% as fixed-line service revenue accelerated to a 4.4% pace from 2.7% in the third quarter. Corporate networks revenue increased 14.2% while broadband revenue rose 6.3% annually. In the mobile segment service revenue growth of 2.6% was mostly driven by postpaid revenue, up 3.3%.

Adjusted EBITDA +6.7% YoY

EBITDA for the period, 599 million Peruvian soles, was 6.7% higher—adjusting for the effect of tower sales a year before—than that of the year-earlier quarter. The EBITDA margin jumped 2.8 percentage points to 37.4%.

Ecuador

65k wireless net adds

We added 65 thousand mobile subscribers in the fourth quarter, 15 thousand of which were postpaid, ending the year with 9.4 million subs, 4.4% more than a year before. On the fixed-line platform we connected ten thousand new broadband accesses but disconnected five thousand voice lines, closing December with 560 thousand fixed-line RGUs.

Postpaid revenue growth +2.4% YoY

We faced during the quarter certain economic and security challenges that have had an impact on the quarter’s operating and financial performance. Service revenue came in 0.3% below that of last year mirroring the decline in mobile revenue as postpaid revenue growth of 2.4% failed to compensate a 3.6% decline in prepaid revenue. Additionally, fixed-line service revenue was off 0.7% year-over-year, in spite of the double digit growth of revenue from both corporate networks and PayTV services, which still account for a small share of total service revenue.

Adjusted EBITDA +4.8% YoY

EBITDA came in at 129 million dollars, a 4.8% year-on-year increase, correcting for one-offs booked in the fourth quarter of last year related to the freeing-up of reserves associated with certain payment obligations. Relative to revenue, the margin expanded 180 basis points (2.1 percentage points on an adjusted basis) to 48.5%. The increase in EBITDA is the result of extraordinary efforts to control expenses.

Argentina

For comparison purposes all comments in this section related to annual variations of the presented period for Argentina refer to figures in constant peso terms, that is, adjusted for inflation in accordance to NIC 29. Information for Uruguay and Paraguay is not presented in the table.

402k wireless net adds

We added 402 thousand wireless subscribers in the quarter, 124 thousand were contract clients. Our wireless base ended the period with 24.9 million subs, 4.4% more than a year before. On the fixed segment we continue to see strong momentum for broadband where we connected 51 thousand new accesses in the quarter taking the total adds to 125 thousand RGUs. Our base was up 26.1% over the year to 3.2 million RGUS.

Service revenue -6.0% YoY

Revenue came in 10.7% below last year’s service revenue that fell 6.0% in real terms. Growth on the fixed-line platform of 4.2%—supported by broadband and PayTV revenue—was offset out by the decline in mobile service revenue.

Devaluation of the currency affected dollar denominated costs

The quarter’s EBITDA fell 12.5% following the decline in revenue and exacerbated by the devaluation of the Argentinean peso that affected, in an important manner, our dollar denominated costs. The EBITDA margin for the period stood at 38.5% down from 39.3% in the last quarter of 2022.

In a public auction conducted in October, we were granted the use of 100MHz of spectrum in the 3300-3400MHz frequency to deploy 5G networks in Argentina.

Caribbean

67k wireless net adds, 55k coming from the Dominican Republic

We added 67 thousand new wireless subscribers in the islands, 55 thousand in the Dominican Republic and 12 thousand in Puerto Rico. We ended December with 7.6 million subs altogether, 3.4% more than a year before. On the fixed-line platform we finished the year with 2.8 million RGUs after connecting 18 thousand new RGUs, of which 13 thousand were broadband accesses.

Service revenue +3.8% YoY and EBITDA +3.4% YoY in the Dominican Republic

Total revenue in the Dominican Republic was up 3.5% on the back of service revenue that rose 3.8%; accelerating from 3.4% in the prior quarter. Mobile service revenue increased 4.3% and the one from the fixed-line platform expanded 3.1%, almost twice as rapidly as in the prior quarter. EBITDA increased 1.0% as compared to the same period of 2022. The annual comparison is affected by a restatement of a depreciation charge of certain assets, organic EBITDA growth was 3.4% with an EBITDA margin of 51.1%.

EBITDA margin at 16% of revenue in Puerto Rico

In Puerto Rico we booked revenue of 232 million dollars in the quarter. Service revenue was down 2.3% compared to last year with declines in both platforms. EBITDA—adjusted by extraordinary revenue booked both in the fourth quarter 2023 and in the same period of last year—was up 34.2% with the adjusted margin reaching 16.1% of revenue.

318k wireless net adds

We registered wireless net additions of 318 thousand in Austria most of which originated in the machine-to-machine business. We finished the year with 10.2 million wireless subscribers which is 14.1% more than a year before. On the fixed-line segment we reached 2.8 million fixed-line RGUs having disconnected 24 thousand RGUs, most of them voice lines.

Wireless service revenue +3.3% YoY

Fourth quarter revenue totaled 714 million euros, 0.6% higher than that of a year before, with service revenue rising 1.8% year-on-year. Wireless service revenue rose 3.3% whereas fixed-line service revenue increased 0.6%. PayTV revenue rose 11.6% while revenue from broadband and corporate networks increased 2.4% and 2.0%, respectively.

EBITDA margin of 37.5% of revenue

EBITDA for the quarter was 276 million euros, up 12.9% year-on-year. This figure includes the reversal of a duties booked the prior quarter associated with the tower spin-off. Adjusting for this effect, EBITDA growth was practically flat and the margin would have been equivalent to 37.5% of revenue.

62k postpaid net adds and 25k new broadband accesses

Altogether we gained 62 thousand postpaid subscribers in Eastern Europe but disconnected 266 thousand prepaids bringing our wireless base to just over 15 million mobile subscribers. On the fixed-line platform Bulgaria and Belarus led the way. We connected 25 thousand new broadband accesses and the same number of PayTV units, but disconnected five thousand voice lines. At the end of December we had 3.4 million fixed-line RGUs, 5.1% more than a year before.

Fixed-line service revenue +14.5% YoY

Total revenue reached 661 million euros, 4.3% more than a year before, on the back of fixed-line service revenue that expanded 14.5% as mobile revenue growth was flat. Corporate networks revenue is the most dynamic business line rising 30.2% followed by broadband revenue, up 13.6% annually. The annual comparison in the financials is affected by the 26.1% devaluation of the Belarusian ruble in the fourth quarter: at constant exchange rates service revenue growth was 9.9%.

EBITDA +7.9% YoY

EBITDA was up 7.9% in euros—15.5% at constant exchange rates—as a result of strong top line growth and cost controls. The margin for the period stood at 33.2% of revenue, up 1.1 percentage points.
