Telefónica is a telecommunications company operating primarily in Europe and Latin America, with roughly 390 million total accesses. Its core products are mobile and fixed broadband connectivity, sold to residential and enterprise customers under brands including Movistar, O2, and Vivo. Telefónica charges customers a recurring monthly fee for connectivity services, with higher-value contract mobile and fiber subscribers generating the most predictable and profitable revenue. Telefónica also sells handsets and equipment, though this revenue stream is declining. The company operates through five segments: Spain, Germany, Brazil, the UK (via a 50/50 JV with Liberty Global called VMO2), and Hispam (Latin America ex-Brazil). Spain and Brazil are the most profitable markets; Hispam is the most challenged, facing FX pressure, competitive headwinds, and ongoing restructuring, including the sale of Argentina in early 2025 and the insolvency filing of its Peru unit. Telefónica is actively migrating customers from legacy copper and 2G/3G networks to fiber and 5G, which reduces operating costs over time. On the enterprise side, Telefónica Tech sells cloud, cybersecurity, and IoT services to business customers, growing at double digits and targeting €3B in revenue by 2026. Telefónica is also monetizing its infrastructure through joint ventures and partial sell-downs, and management has signaled interest in leading broader European telecom consolidation.
