América Móvil (AMX) Q3 2026 Earnings Call Transcript

América Móvil reported third-quarter revenue of MXN 251 billion, up 7.6% year over year, and an EBITDA margin of 40.8%, 0.5 percentage points higher; postpaid service revenue grew 7.5% at constant exchange rates. Net debt fell MXN 34 billion in cash-flow terms to MXN 400 billion excluding leases, while net debt to EBITDA after leases declined to 1.21x from 1.51x at end-2025; the company distributed MXN 27 billion through buybacks and dividends in the first nine months. Management expects 2026 and 2027 capex of about $7 billion annually, sees a possible short-term prepaid revenue slowdown in Mexico amid subscriber registration, and expects the BRL 4 billion Desktop acquisition to close after year-end.

Analysis

The constructive signal is mix and operating leverage, not headline subscriber growth: postpaid upgrades and fixed-broadband upselling can lift revenue per customer without requiring proportionate net additions. But Mexico’s prepaid cleanup and registration requirement make reported disconnections a poor near-term read-through to underlying demand; verify prepaid service revenue and churn over the next two quarters before treating postpaid migration as durable net growth.

Near term, FX can blunt the operating progress: reported revenue benefits from currency translation are not equivalent to constant-currency growth, while the quarter’s FX losses show how quickly financing costs can diverge from operating trends. The 1.21x leverage ratio offers room for distributions, but Desktop integration, the pending Peru transaction, and the next dividend compete for that capacity. Brazil’s fiber footprint may create cross-sell upside, but synergies are a management thesis until subscriber conversion, churn, and integration costs are disclosed.

Over 1–3 months, monitor Mexico prepaid service revenue, currency-adjusted EBITDA, and Desktop closing/integration. Over 6–18 months, AI-driven cost savings and fiber/mobile bundling matter only if they show up in cash generation rather than capex or promotional intensity. The contrarian risk: strong postpaid ARPU and margin expansion may already be extrapolated, while promotional competition in Brazil and uncertain Mexican regulation can reverse the mix benefit. Management’s comments on prospective competitors in Mexico and Argentina are not evidence of their eventual pricing or market impact.

Key Decisions for Investors

• Constructive bias on AMX, but avoid chasing the earnings reaction without valuation context. Consider a starter long on weakness; add only if subsequent results sustain constant-currency service-revenue growth and EBITDA outgrowth.
• Use Mexico prepaid service revenue and churn as the key falsification tests. If they deteriorate beyond a temporary registration-related disruption while postpaid growth slows, reduce the thesis rather than assuming automatic migration.
• Track Desktop closing, integration costs, broadband net adds, and cross-sell indicators through the next 1–3 quarters. Treat stated synergies as unproven until they support cash flow without increased promotional intensity.
• Do not underwrite buybacks solely from the leverage ratio: monitor net debt after distributions and M&A, alongside FX-driven financing costs. A renewed leverage increase or weaker free cash flow would challenge the capital-return case.
