América Móvil, S.A.B. de C.V. AMX combines continued postpaid and broadband growth with healthy cash generation, while its shares trade above both sub-industry and five-year median book-value benchmarks.

For investors considering a fresh position, the question is whether recurring revenue growth and disciplined capital allocation can offset the premium valuation and execution risks.

AMX's Valuation Leaves Less Room for Error

AMX trades at 2.85X trailing 12-month book value, well above the 1.35X level for its Zacks sub-industry. The stock also sits above its five-year median of 2.64X.

That premium raises the bar for execution. Continued subscriber gains, cost control and margin improvement become more important when investors are paying above both the peer benchmark and the stock's own historical norm.

America Movil's Cash Generation Supports Flexibility

First-half 2026 cash generation covered Mex$48 billion of capital expenditures, Mex$4.6 billion of share buybacks and Mex$8.4 billion of labor obligations. Net debt declined by Mex$30.9 billion in cash-flow terms.

Net debt excluding capitalized leases ended June at Mex$402 billion, equal to 1.31 times last-12-month EBITDA after leases. That keeps AMX within management's 1.2-1.5 times leverage range while it funds investments and acquisition commitments.

AMX's Subscriber Mix Supports Recurring Revenue

Postpaid users increased 9.1% year over year in the second quarter, while broadband accesses rose 6.1%. AMX added 3.5 million postpaid subscribers and 531,000 broadband accesses during the period.

Prepaid users fell by 3.7 million after customer-base cleanups in Colombia and Argentina. Management expects migration from prepaid to postpaid to continue over the next five years, supporting more recurring service revenues.

America Movil Still Faces Execution Risks

Brazil remains a competitive pressure point, with management citing more aggressive promotions in prepaid and postpaid. TIM S.A. TIMB targets roughly 5% service revenue growth and 6%-8% EBITDA growth in 2026, providing a useful operating benchmark in that market.

Telefônica Brasil S.A. VIV reported 105.1 million mobile lines and 37.8% mobile market share as of the second quarter. AMX also faces Mexico's prepaid registration transition, currency volatility, macroeconomic uncertainty and acquisition commitments.

AMX's Earnings Profile Sends Mixed Signals

Second-quarter net income increased 9.2% year over year to Mex$24.3 billion. EBITDA rose 5.3% at constant exchange rates and would have increased 6.7% excluding a one-off charge in Mexico.
