Lumen Technologies is one of the largest telecommunications carriers serving global enterprises. The merger with Level 3 in 2017, the 2022 divestiture of much of its local phone business in rural areas, and the 2026 sale of its remaining consumer fiber network to AT&T have shifted the company's operations away from the legacy consumer business and toward enterprise services, which account for about 85%-90% of revenue. Lumen offers businesses a full suite of communications services, providing colocation and data center services, data transportation, phone service, and internet access.
