What it stands on, and what could break it

What the business leans on

1Comcast relies on Verizon's mobile network for U.S. residential wireless service and began using T-Mobile's network for business wireless service in 2026.
2In the United Kingdom and Italy, some broadband and video services rely on networks or satellite capacity owned by other companies.
3Television and streaming services depend on licensed programs and sports rights, including agreements with sports leagues and other rights owners.
4Comcast buys some customer equipment, network equipment, wireless devices and billing services from a limited number of suppliers.

What could go wrong

1Fiber internet, fixed wireless, satellite and other providers compete for broadband customers; streaming services and changing viewing habits also contribute to losses of traditional television customers.
2The company depends on viewers accepting its films and programs and on renewing programming and sports rights agreements; rights costs can rise, and content that draws fewer viewers can reduce advertising and licensing revenue.
3A cyberattack, security breach or technology disruption could interrupt network or media services, expose confidential information and affect customer trust.
