Verizon is a toll collector on American connectivity. Every month, roughly 93 million postpaid wireless customers pay between $65 and $90 per line for the privilege of using spectrum that Verizon bought from the federal government. That's the core of the business — not devices, not media, not enterprise consulting. Monthly wireless bills. The Consumer segment generated $106.8 billion in 2025 revenue. Break that apart and you find three layers. First, wireless service revenue: the monthly plan fees from postpaid and prepaid customers. This is the highest-margin, most predictable stream. Postpaid churn runs below 1% monthly, meaning once someone signs up, they tend to stay. Verizon structures its unlimited plans in tiers — Welcome Unlimited at the bottom, Unlimited Ultimate at the top — with each step up adding hotspot data, better streaming quality, international roaming, and device upgrade eligibility. The spread between tiers is $15-20 per line per month, and the entire myPlan architecture exists to nudge customers upward. Second layer: equipment revenue. Verizon sells iPhones and Samsung Galaxies, but this isn't really a retail business. It's a financing operation. Customers pay for $1,000+ devices over 36 monthly installments, which locks them into the network for three years without technically being a 'contract.' Equipment margins are thin — sometimes negative after trade-in credits — but the retention value is enormous. A family of four with three phones on installment plans faces $2,000+ in remaining device payments if they want to switch carriers. Third layer: broadband. Fios fiber serves roughly 7 million internet subscribers in the Northeast and Mid-Atlantic. Fixed wireless access — using 5G and LTE signals to deliver home internet without a cable — has been growing at over a million subscribers per year and now serves several million homes. The January 2026 Frontier acquisition added fiber passing nearly 30 million premises across 31 states, roughly tripling Verizon's fiber addressable market overnight. The Business segment adds another $31+ billion, selling private networking, managed security, SD-WAN, unified communications, and IoT connectivity to enterprises and government agencies. These are multi-year contracts with higher margins than consumer wireless but slower growth. The financial architecture is simple but punishing: Verizon spends $18-20 billion annually on capital expenditure — towers, fiber, spectrum deployment, small cells, equipment upgrades. It carries approximately $150 billion in debt. Operating margins in wireless run 30-35%, which sounds healthy until you realize that interest expense alone consumes roughly $7 billion per year. The company trades at about 1.3x revenue, which is utility pricing. Investors buy Verizon for the 6%+ dividend yield, not for growth. The market capitalization of ~$174 billion reflects a bet that this cash machine keeps running, not that it accelerates.
