Latest financial snapshot
Financial summary
AT&T
AT&T's financial story is large revenue, large debt and a slow correction. The company funded the $48.5 billion DirecTV purchase in 2015 and the $85.4 billion Time Warner purchase in 2018 largely with borrowing, and net debt passed $180 billion after Time Warner closed. It then reversed course: WarnerMedia was separated in 2022, the dividend was cut, and the remaining 70% DIRECTV stake went to TPG in July 2025 for a $5.6 billion gain. FY2025 revenue was $125.6 billion, with $23.4 billion of total net income, $46.4 billion of adjusted EBITDA and $16.6 billion of free cash flow against $117.4 billion of net debt. Roughly $22 billion a year of capital investment goes mostly into fiber and 5G.
Cisco
Cisco's revenue fell 5.6% to $53.8 billion in FY2024 as customers worked through excess inventory, then recovered to $56.7 billion in FY2025 and a record $63.3 billion in FY2026 (up 12%). FY2026 GAAP net income was about $13.3 billion, GAAP EPS was $3.33 (up 31%), and non-GAAP EPS was $4.33. Growth accelerated through the year: Q4 FY2026 revenue was $17.3 billion, up 18%, with product revenue up 24% and total product orders up 35%. Cisco said it recognized about $4 billion of AI infrastructure revenue from hyperscalers in FY2026 and expects about $7.5 billion in FY2027, within total FY2027 revenue guidance of $72.2-73.4 billion. The company also pays a quarterly dividend and buys back stock.

Business model and strategy
AT&T
How it makes money
AT&T runs a capital-intensive network business. It buys licensed wireless spectrum, builds and upgrades cell sites, and trenches fiber, then charges consumers and businesses a monthly fee to use that network. Capital investment was $22.0 billion in 2025 against $125.6 billion of revenue.
Growth strategy
With the US smartphone market saturated, AT&T's growth depends on home internet and on keeping the wireless customers it has. It is building fiber, which passed 32.0 million consumer and business locations at the end of 2025 and carried 10.4 million subscribers, and it sells AT&T Internet Air fixed wireless where fiber is not available.
Competitive advantage
AT&T's advantage is the cost of replicating what it already owns. Its fiber network passed 32.0 million consumer and business locations at the end of 2025, and its mid-band 5G service covers more than 310 million people. Keeping that going took $22.0 billion of capital investment in 2025 alone, which is why the national market has three carriers rather than thirty.
Cisco
How it makes money
Cisco makes money in two ways: product sales and services. Products (switches, routers, wireless, Silicon One-based data center and AI networking gear, firewalls, Splunk and other security and observability software, and Webex) made up about $13.5 billion of the $17.3 billion Q4 FY2026 revenue, while services (technical support, advisory, and maintenance contracts) contributed about $3.8 billion.
Growth strategy
Cisco's growth plan rests on three areas. First, AI infrastructure: Silicon One chips, Nexus and Cisco 8000 systems, and optics sold to hyperscalers and, increasingly, to neoclouds, sovereign AI projects, and enterprises building their own AI clusters. Second, campus and branch refresh, as enterprises upgrade switching and Wi-Fi for AI workloads.
Competitive advantage
Cisco's advantage is how deeply its equipment is built into corporate networks. The saying in IT is that 'nobody ever got fired for buying Cisco': large banks and other enterprises choose it for reliability. Replacing an integrated Cisco network with cheaper hardware is a multi-year project with real risk, so most CIOs stay, which gives Cisco a durable installed base.
