Executive summary

América Móvil Q3 FY25 — mobile service revenue posts best growth in 2 years as postpaid adds top 3 million

América Móvil's quarter is a mobile reacceleration story: prepaid and postpaid revenue are both running at their fastest in two years, powered by Mexico, Colombia and Chile, while EBITDA is again outpacing revenue and deleveraging continues. The offsets are a volatile corporate-networks slowdown dragging fixed-line and a cautious, reserve-heavy stance in Colombia. Forward posture is opportunistic M&A — an early-stage Chile joint bid with Entel for Telefónica's assets and a Brazilian ISP review.

Highlights

5
  • Added just over 3 million postpaid clients in the quarter (Brazil 1.5M, Colombia 251K, Peru 198K, Mexico 98K); postpaid base up 8.1% YoY to 140 million

  • Mobile service revenue grew 7.1% (best in 2 years) — prepaid +3.9% (fastest in 2 years), postpaid +9.1%; total revenue MXN 233B, +4.2% (+6.2% constant FX)

  • EBITDA MXN 94B, +4.9% nominal / +6.8% constant FX (adjusted for prior-year tower sales), reverting to EBITDA outgrowing revenue

  • Free cash flow MXN 53B for the 9 months, up 47% YoY from MXN 36B; net debt cut by MXN 16B to MXN 454B (1.55x net debt/EBITDA after leases)

  • Fixed broadband gained 526K accesses (Mexico 211K); net income surged to MXN 23B (MXN 0.38/share, $0.40/ADR)

Concerns

4
  • Fixed-line service revenue decelerated to 4.7% from 7.9% prior quarter as corporate networks revenue growth fell from 15% to 3.5%

  • Prepaid platform recorded net disconnections of 31,000 (losses in Brazil, Ecuador and Chile)

  • Colombia EBITDA growth held to ~3% (vs ~5% possible) due to precautionary reserves being set through year-end for legal/fiscal matters

  • Mexican prepaid recovery remains hostage to the macro/economy, which management flagged is only gradually improving

Deals & partnerships

Telefónica (Chile) / Entel acquisition (potential joint bid)

América Móvil is evaluating a potential joint bid with Entel to purchase Telefónica's assets and operations in Chile. Early stage; due diligence and number-checking ongoing; process expected to take time. No binding commitment disclosed.

Desktop (Brazil ISP) acquisition (under evaluation)

América Móvil's Brazilian subsidiary is evaluating 'desktop' (an ISP), but management stated no binding commitment exists to date.

Liberty (Chile) acquisition (completed)

Referenced as already completed — América Móvil bought the Liberty shares/stake in Chile; integration and synergies drove the Chile turnaround (rebranding to Claro, 5G, cable-to-fiber migration).

Risks & headwinds

Corporate networks revenue volatility dragging fixed-line growth Q3 2025; inherently volatile going forward

Corporate networks revenue growth fell from 15% (Q2) to 3.5% (Q3); fixed-line service revenue decelerated to 4.7% from 7.9%

Mitigation:Management notes volatility is structural (tied to corporate contract/IT project pipeline); segment now 21% of fixed-line service revenue and growing

Prepaid net disconnections Q3 2025

31,000 net prepaid disconnections in the quarter (losses in Brazil, Ecuador, Chile)

Mitigation:Offset by prepaid gains in Argentina (253K), Colombia (237K) and Mexico (136K); prepaid revenue still grew 3.9%

Precautionary reserves suppressing Colombia EBITDA Through end of 2025

Colombia EBITDA growth held to ~3% vs ~5% possible; reserves for legal/fiscal ('physical and legal') matters run through year-end

Mitigation:Management characterizes reserves as conservative; underlying operations growing well (service revenue +7.8%)

Macro dependency of Mexican prepaid recovery Q4 2025 into 2026

Not quantified; prepaid recovery explicitly tied to the economy, which is only gradually improving

Mitigation:Management monitoring; expects recovery to continue if economy improves

Competitive intensity and low pricing in Chile Ongoing

Not quantified; prices described as 'very low' with high competition

Mitigation:Network modernization, 5G, Claro rebranding, cost discipline and better subscriber mix; EBITDA more than doubled

Regulatory approval risk on regional consolidation (Colombia) Ongoing

Not quantified; Tigo/Telefónica consolidation awaiting government authorization

Mitigation:América Móvil positioned as #1 in 5G in Colombia; monitoring competitive outcome

Q&A highlights

Is the Mexico prepaid revenue recovery macro-driven and continuing into Q4? Was the strong Chile/Uruguay/Paraguay margin expansion due to accounting/one-offs after the JV ended?

CEO said Mexican prepaid recovery is very related to the economy, which troughed late 2024/early 2025 and has been recovering since; sustainability depends on macro. On Chile, he attributed margin gains to genuine operations — synergies after buying the Liberty shares, better/higher-ARPU postpaid subscribers, improved churn and cost discipline — not accounting or one-offs.

“There's nothing different on that. So that's only the operations and the growth that we have been having better churn, good subscribers -- better subscribers because we used to have the lowest segment of subscribers were having better postpaid subscribers, better revenue, better ARPUs, all of this is helping us to grow our EBITDA”

Detailed narrative

Macro backdrop and FX

CFO Garcia Moreno framed the quarter against a slowing U.S. economy, evidenced by a sharp decline in new jobs and a September Fed rate cut of 25 bps. Ten-year U.S. rates fell from nearly 4.5% to 4.1% since mid-July. The weaker dollar lost ground across América Móvil's region: down 2.7% vs the Mexican peso, 2.5% vs the Brazilian real and 4.1% vs the Colombian peso, roughly flat vs the euro, while the Argentine peso depreciated against the dollar.

This peso appreciation explains the gap between nominal (+4.2%) and constant-FX (+6.2%) revenue growth.

Subscriber additions across the footprint

The company added just over 3 million postpaid clients, with Brazil contributing roughly half (1.5M), followed by Colombia (251K), Peru (198K) and Mexico (98K). Prepaid saw net disconnections of 31,000 overall — losses in Brazil, Ecuador and Chile offset by additions in Argentina (253K), Colombia (237K) and Mexico (136K).

Fixed broadband gained 526,000 accesses, led by Mexico (211K), Brazil (86K), Argentina (56K) and Colombia (51K). Total accesses reached 408 million: 140 million postpaid, 79 million fixed-line RGUs.

Mobile revenue reacceleration

Mobile service revenue posted its best growth in two years at 7.1%. Prepaid revenue expanded 3.9% — the fastest pace in two years, driven by macro-linked recovery — while postpaid climbed 9.1%, similar to the prior quarter's fastest-in-10-quarters pace. Mexico, Colombia and Chile were the main operations behind the acceleration.

Management tied the prepaid recovery directly to the economy, noting the trough was late 2024/early 2025.

Fixed-line and corporate networks

Fixed-line service revenue decelerated to 4.7% (from 7.9% the prior quarter), driven by a sharp slowdown in corporate networks revenue, which fell from a 15% increase in Q2 to just 3.5% in Q3. Management noted corporate networks revenue is inherently volatile, tied to the pipeline of corporate contracts and IT projects, and has grown to represent 21% of fixed-line service revenue — an increasingly important segment for the company.

Cash flow, capital returns and balance sheet

Over the nine months to September, operating cash flow was MXN 138 billion (EBITDA after leases less MXN 34B working-capital increase and MXN 67B interest and taxes). Capex totaled MXN 85 billion. Free cash flow of MXN 53 billion (up 47% YoY from MXN 36B), plus MXN 2.3B dividend income, funded MXN 29 billion distributed to shareholders (including MXN 11B in buybacks), a MXN 1B increase in equity investments, MXN 10B in labor obligations, and a MXN 16B net-debt reduction.

Net debt ended at MXN 454 billion, or 1.55x net debt/EBITDA after leases.

Chile turnaround

Management highlighted Chile (grouped with Uruguay and Paraguay) as a strong margin story: after buying the Liberty stake, modernizing the network, deploying 5G, expanding coverage and rebranding to Claro, the operation is winning better-quality postpaid subscribers with better ARPUs and churn.

EBITDA in Chile has more than doubled. Management stressed synergies take time but the operation is in 'a very good moment,' while cautioning that Chilean prices remain very low and competition high.
