Qwest Corporation, an indirect wholly owned subsidiary of Lumen Technologies, provides digital networking services to business and remaining mass‑market customers over a largely fiber-based network. The company focuses on enterprise connectivity, optical and ethernet services, and legacy voice and private line offerings managed for cash flow.
A major strategic shift was the February 2, 2026 completion of the sale of its Mass Markets Fiber-to-the-Home business in 11 states to AT&T for $5.75 billion in gross cash proceeds, subject to adjustments. Qwest also exited the Rural Digital Opportunity Fund program, reversing related revenue of $11 million and recognizing $12 million of fees, followed by a $26 million repayment in January 2026.
As of December 31, 2025, Qwest employed about 9,100 people, with roughly 43% represented by CWA or IBEW unions. The filing highlights extensive business risks, including intense competition, rapid technology change and AI-related uncertainty, high debt across the Lumen group, cybersecurity threats, complex telecom regulation, climate and environmental exposure, divestiture execution challenges, and dependence on key vendors, customers, and government programs.
