América Móvil Consolidated Results

During the third quarter supply shortages were prevalent in several industries at a global level, helping inflation data continue to surpass estimates in the U.S. and other countries. The market consensus appeared to shift in favor of the Fed and other monetary authorities moving more rapidly than anticipated to ease the expansion of the monetary base and set the base for interest rates to begin to rise. In this context ten-year interest rates on U.S. Government Notes experienced a marked correction just prior to the end of the quarter, helping strengthen the U.S. dollar vs. most currencies, including the euro and several Latin American ones, closing the quarter higher vis-à-vis all of them.

Service revenue +4.5% YoY at constant Fx

Our revenue totaled 253.4 billion pesos in the quarter, a 2.6% decline in nominal peso terms, with service revenue falling 2.1%. At constant exchange rates service revenue actually increased 4.5% year-on-year, slightly less than in the second quarter—it had marked the highest point of the revenue rebound since it was that period of 2020 that was most affected by the pandemic—but much higher than the 1.2% posted in the first quarter.

The difference between the nominal peso figures and those at constant exchange rates reflects the appreciation of the Mexican peso vis-à-vis all other currencies in our region throughout the period of comparison, with the peso gaining 10.2% vs. the dollar, 9.3% vs. the euro, 25.8% vs. the Peruvian sol, 13.6% vs. the Colombian peso and 7.2% vs. the Brazilian real.

Mobile service revenue +5.9% YoY

Mobile service revenue was up 5.9% year-on-year at constant exchange rates with prepaid revenue rising 5.4% and postpaid revenue 6.4%. Mexico and Brazil both increased their mobile service revenue 9% with Peru posting 15.8% and El Salvador 12.8%. Among our European operations Bulgaria, Croatia, Macedonia and Serbia all registered better than 10% revenue increases. At 6.9%, Austria’s revenue growth was buoyed by 5G services and fixed-mobile devices.

Broadband and corporate network revenue up 5.6% and 4.6% YoY, respectively

Fixed-line service revenue increased 1.6% as fixed-broadband and corporate network revenue expanded 5.6% and 4.6%, respectively and PayTV revenue fell 5.2%, with clients in Brazil continuing to revise down the cost of their PayTV plans reflecting a greater share of content coming from streaming services as opposed to the traditional multichannel offerings. On the fixed-line platform revenue growth was noteworthy in Peru, 18.8%, and Colombia, 9.8%, with Bulgaria posting 15.5% growth and Belarus and Serbia expanding their revenue more than 20%.

Costs and expenses were up 1.9% at constant exchange rates with expenses increasing 0.7%. Bad debt provisions were reduced 47%.

EBITDA margin, 34.6%, highest in nine years

EBITDA came in at 87.6 billion pesos, a 1.3% increase over the year-earlier quarter in nominal peso terms and a 7.5% rise at constant exchange rates as service revenue expanded twice as rapidly as costs and expenses. Our EBITDA margin jumped to 34.6% from 33.2% the prior year—it was our highest EBITDA margin in nine years. Mexico, Central America, the Dominican Republic and Peru were behind this margin expansion, having the first three of them registered three percentage-point improvements, and Peru’s 2.5.

Our Brazilian operation picked up 1.1 million postpaid and 307 thousand prepaid subscribers in the third quarter. At the end of September it had nearly 70 million subscribers, with its postpaid base having increased 19.6% from a year before. On the fixed-line platform it lost 20 thousand fixed-broadband accesses and 181 thousand PayTV clients.

Mobile service revenue +9.0% YoY with postpaid revenue +11%

Third quarter revenue was up 0.4% to 9.8 billion reais, as service revenue expanded 1.1% and equipment revenue declined 22.7%. Service revenue increased rapidly on the mobile platform, 9.0%—its second better performance over the last five quarters—falling 5.0% on the fixed-line platform, a pace of decline similar to that seen over the last several quarters.

Mobile revenue were driven by postpaid services, whose revenue was up 10.7%, with prepaid revenue climbing 3.2%. The churn rate improved by 1.7 percentage points, falling to 3.0%.

Fixed-line broadband revenue +4.7% YoY

On the fixed-line platform broadband revenue rose 4.7%, showing a deceleration from the nearly 10% pace observed during the first half of 2020. Corporate network revenue climbed 2.7% while PayTV revenue declined 12.5%, in line with the revenue reductions observed throughout the prior quarters.

EBITDA margin at 40.2%

EBITDA of 4.0 billion reais was slightly up from the year before, 0.2%, partly bogged down by a 6.1% increase in selling and marketing expenses given the strong commercial activity and postpaid net subscriber additions. Our EBITDA margin came in at 40.2%, barely down from the year before, 40.3%.

Depreciation and amortization expenses were up 3.3% year-on-year mostly as a result of the phasing out of parts of the Nextel assets, leading to a 4.6% reduction in operating profits.

253k mobile net adds

Our Eastern European operations gained 253 thousand wireless subscribers and six thousand fixed-line RGUs in the third quarter, all of them broadband accesses. At the end of September they had 15.1 million mobile subscribers and 3.0 million RGUs.

Service revenue +10% YoY

All of our operations in Eastern Europe posted service revenue growth in the third quarter. Altogether they generated service revenue of 424 million euros, 10.4% more than a year before. Most of the countries have benefited from the fast adoption of fixed-mobile offerings, from a rebound of roaming revenue and from 5G services with higher tariff plans, all of which helped bring about a 10.8% increase in mobile service revenue. Fixed-line service revenue also showed a solid performance, growing 9.2% thanks to upselling of broadband plans to higher speeds and bandwidth in every country and to greater PayTV and content offerings in Bulgaria and Croatia. In Belarus, service revenue increased 9.4% due to strong commercial performance in the postpaid segment and to upselling and cross-selling to multi-play offerings in the fixed-line segment.

EBITDA up 11% YoY

EBITDA reached 212 million euros, 11.3% more than in the year earlier quarter. All countries reported strong EBITDA growth—except for Slovenia which had much higher advertising and maintenance costs—as a result of top line growth and cost control. The EBITDA margin was up 40 basis points to 38.8%
