What it stands on, and what could break it
What the business leans on
- 1Wireless service depends on government licenses to use radio spectrum; AT&T must maintain and renew those licenses and obtain enough capacity for network traffic.
- 2Network construction and service depend on equipment and other supplies from third-party vendors, including equipment used in wireless networks and customer devices.
- 3Service depends on the continued operation of extensive wireless, fiber, and legacy wired infrastructure, which can be affected by cyberattacks, extreme weather, or other physical damage.
- 4A significant share of employees is represented by labor unions, so contract negotiations and work stoppages can affect operating costs or service work.
What could go wrong
- 1AT&T needs ongoing access to radio spectrum and substantial investment in its wireless and fiber networks to meet customer demand; spectrum availability, license terms, or higher network costs could affect service and operations.
- 2Wireless carriers, cable companies, fixed wireless providers, and other internet services compete for customers on price, coverage, network quality, and devices, while customers continue to move away from older copper-based services.
- 3Cyberattacks, extreme weather, infrastructure damage, or delays in equipment supply can disrupt AT&T's networks or its ability to serve customers.
