AT&T (SOBA.DE) Stock Analysis & Winston Score
AT&T is one of the largest telecommunications companies in the United States. It provides mobile phone service, home internet, and fiber-optic broadband to tens of millions of consumers and businesses across the country. The company also sells wireless plans and devices directly to customers through its retail stores and online. AT&T earns most of its revenue through monthly subscription fees for wireless and internet service, which creates a steady, recurring income stream. It operates primarily in the United States and reported roughly $122 billion in annual revenue in recent years, making it one of the biggest companies in its industry. Its large existing network infrastructure is a significant barrier for competitors, but AT&T carries a heavy debt load — largely from past acquisitions — which limits its financial flexibility and remains a key risk. The main growth driver going forward is continued expansion of its fiber internet network and 5G wireless coverage.
