América Móvil's second quarter arrived with the company doing what it has done for a decade: posting modest top-line growth in nominal terms while the underlying business moves faster, sweeping cash back into the balance sheet, and adding customers at scale. There are two ways to read the headline. The first is sleepy: revenue rose 3.1% to Ps. 241,071 million (about $13.9 billion), a number that looks pedestrian in a quarter when most major emerging-market telecoms are celebrating double-digit local-currency growth. The second reading tells a different story. The Mexican peso appreciated 12.3% against the U.S. dollar year over year, mechanically depressing reported revenue at the consolidated level; at constant exchange rates, service revenue rose 5.1%. Net income climbed 9.2% to Ps. 24,332 million - about $1.4 billion - with earnings per ADR of $0.47 (basic and diluted, 40 peso cents per share). The bigger story is what the company did with the cash: net debt fell by Ps. 31 billion in the first half to 1.31 times LTM EBITDAaL, a leverage ratio that puts América Móvil in the same conversation as the cleanest-rated telecoms in the world. A one-off regulatory fine at Telmex held reported Mexico EBITDA to +0.6%; without it, consolidated EBITDA would have grown 6.7% instead of the reported 3.8%. The headline understates the engine. The engine is the story.
Each of the four largest segments had its own quarter. Mexico - roughly 36% of consolidated revenue - saw service revenue accelerate to 4.4% with mobile service revenue at 6.6%, the strongest postpaid performance in several quarters; the regulatory fine is a one-quarter, one-line issue, not a margin story. Brazil - the second-largest engine - delivered 5.4% revenue growth and 5.1% EBITDA growth in local currency, with postpaid net additions of 1.5 million. Central America and the Caribbean posted double-digit EBITDA growth (+12.5% USD-denominated), and Austria and Eastern Europe - A1 Group, the smallest of the four big engines - added more than a million mobile subscribers (substantially all M2M) and grew EBITDA 4.0% in euros. Argentina delivered the highest segment EBITDA growth (+22.2% in hyperinflation-adjusted pesos) but is, by accounting policy, excluded from the constant-currency comparisons. The portfolio did what a multi-country telecom portfolio is supposed to do: it compounded.
Then there is the part of the quarter that needs no interpretation: what the company did with its money. América Móvil repurchased shares worth Ps. 4.6 billion in the first half, brought net debt down Ps. 31 billion, and announced an agreement to acquire 100% of WOW Peru from Liberty Latin America and Narvik Capital Partners - a fiber broadband operator that strengthens its fixed-line position outside Lima. Management has not framed these moves as a transformation; they are the steady, year-in-year-out discipline of a balance-sheet-first operator. At a reference price of $23.22 (the price shortly after the second-quarter results announcement), América Móvil trades at roughly 15 times trailing earnings with a low double-digit return on equity and a leverage ratio that has more room to fall than to rise. The thesis is not a re-rating. The thesis is a compounder at a multiple that already assumes nothing good happens.
