AT&T reported first-quarter revenue of $31.51 billion, a 2.9% increase year-over-year, slightly exceeding consensus estimates of $31.29 billion. Adjusted EPS rose to $0.57, up from $0.51 in the prior-year period, beating expectations of $0.55. Performance was primarily driven by robust growth in the Advanced Connectivity segment, particularly in high-speed fiber and wireless service revenues, alongside initial contributions from the Lumen fiber assets acquired in February. These gains were partially offset by a 25.3% decline in legacy copper-based services as the company continues its network modernization.
Note: AT'T's FY'25 ended on December 31, 2025. Q1 FY'26 ended on March 31, 2026.
On May 4, 2026, AT&T officially launched AT&T Dynamic Defense for small and medium-sized businesses, embedding proactive cybersecurity directly into its fiber network. This strategic pivot aims to monetize the company's fiber infrastructure beyond connectivity by providing hardware-free security solutions. The launch coincides with the 2026 AT&T Small Business Contest and strategic AI collaborations with NVIDIA and Cisco to integrate real-time intelligence at the network edge, signaling a shift toward higher-margin, software-defined connectivity services.
Below are key drivers of AT&T's value that present opportunities for upside or downside to the current Trefis price estimate:

AT&T is a leading provider of telecommunications and technology services, recently restructured into three primary reporting segments: Advanced Connectivity (Wireless and Fiber), Legacy (Copper-based services), and Latin America (Mexico operations). The company is currently executing a multi-year transition to phase out legacy wireline assets while aggressively expanding its 5G and fiber-optic footprint to capture the growing demand for high-bandwidth data and AI-integrated network services.
The Advanced Connectivity segment, encompassing 5G wireless and consumer fiber, remains the cornerstone of the company's valuation due to its massive installed base and recurring service revenue.
AT&T operates the largest fiber network in the U.S., reaching over 37 million locations. This infrastructure acts as a formidable moat, providing a superior cost structure for data delivery compared to cable competitors and enabling high-margin bundled services that improve customer retention.
With a disciplined focus on high-quality postpaid phone additions and 5G spectrum deployment, AT&T maintains strong margins in its Mobility business. The recent $14 billion Open RAN commitment with Ericsson aims to further optimize operating costs, targeting 70% of network traffic on open platforms by late 2026 to enhance vendor flexibility.
The telecom industry is shifting toward AI-native architectures that enable self-healing and autonomous optimization. AT&T is positioning itself at the forefront through collaborations with NVIDIA and AWS, integrating AI directly into the network edge to handle business-grade workloads and reduce operational expenses through predictive maintenance.
AT&T is aggressively accelerating the shutdown of its legacy copper-based network to reduce technical debt and maintenance costs. While this results in short-term revenue declines in the Legacy segment (down 25.3% in Q1), it is a critical strategic pivot to reallocate capital toward higher-growth fiber and 5G infrastructure.
