América Móvil, S.A.B. de C.V.

Revenue comes mainly from recurring subscription and usage fees for wireless and fixed-line service, billed monthly to postpaid customers or collected in advance from prepaid customers, with smaller amounts from pay-television, over-the-top content and equipment sales. The company has been consistently profitable across the years on file, generates free cash flow that is large relative to the assets and equity used to produce it, and in the most recent year on file generated more cash from operations than its reported net income. At the same time, the amount customers owe it has been rising and makes up a large share of its short-term assets.

The company scales primarily by adding capacity onto a network it already owns, funding new spectrum, fiber and site build-out mostly from its own operating cash flow rather than external financing, and by selling more services (voice, broadband, pay-television, over-the-top content) to the same subscriber base over shared infrastructure. It operates in a way of running a network business that only a small number of other companies match: moving traffic through fixed physical capacity that caps how much can pass through it at once.

Its own account names Huawei, Ericsson and Nokia as key suppliers of network equipment and handsets, and separately flags dependence on government-issued spectrum licenses, energy and skilled technical labor needed to build and run its networks. CompanyGraph's supply-chain mapping independently places it with several incoming supplier relationships feeding into this business, consistent with that picture.

Its own account names retail and residential subscribers across prepaid and postpaid wireless and fixed-line service, alongside corporate customers and buyers in the industrial, financial, government and tourism sectors. It also carries traffic for other network operators under roaming and interconnection agreements, and carries content from providers to viewers under its pay-television and over-the-top offerings, so other carriers and content providers route through it as well as end subscribers. CompanyGraph's mapping of its position downstream separately records several outgoing connections, consistent with this picture.

CompanyGraph's mapping of how companies operate places it in an uncommon group: businesses that move traffic or material through fixed capacity with a hard ceiling on throughput, shared by only a small number of other companies on file. This describes how rare that operating position is, not whether competitors could reproduce it. The company's own account separately points to its owned physical network, its combined voice-video-data platform, and its brand, coverage and network quality as the strengths it emphasizes competitively.

Its own account states that most subscribers are prepaid and are not bound by a long-term contract, so the evidence on file does not describe contractual lock-in as the reason customers stay. What it does report is a churn rate described as low and steady from one year to the next, without stating what mechanism produces that stability.

The company's own account names limited spectrum and network capacity, the pace of government authorization for spectrum and new sites, the availability of qualified technical personnel and the timeliness of deliveries from its equipment suppliers as what limits its growth. This aligns with a broader pattern CompanyGraph tests for this kind of business, where fixed physical capacity sets a ceiling on how much traffic can move through the system, though the company frames that ceiling as something it can extend through further spectrum and site approvals rather than as a hard limit.

The company's own filings name intense competition and adverse government or regulatory action as the risks it lists first. They also disclose unresolved regulatory and legal proceedings over interconnection fees and a competition-related fine, reliance on a small number of named suppliers for network equipment and handsets, and exposure to cross-border tariffs, a regional trade-agreement review and sanctions tied to conflict affecting one of its European operations.

Its own filings identify intense competition and adverse government or regulatory action as the risks it names first. It operates under telecommunications, spectrum and competition regulators in each country where it holds licenses, and it separately discloses exposure to cross-border tariff policy, a regional trade-agreement review, sanctions tied to geopolitical conflict touching one of its European operations, and currency movements across the several currencies in which it earns revenue and holds debt.
