The Lumen name launched in 2020 when CenturyLink rebranded, an attempt to shed the copper-telephone-company image and reposition around the Level 3 fiber backbone the company had absorbed in 2017.
The heritage runs deep: Century Telephone Enterprises from 1968, the Qwest acquisition of 2011, and the $34 billion Level 3 merger that delivered one of the world's largest internet backbone networks.
The 2020s were defined by divestiture: the 20-state copper sale that created Brightspeed in 2022, Latin American assets, and finally the February 2026 sale of consumer Quantum Fiber to AT&T for $5.75 billion, completing the enterprise pivot.
Under CEO Kate Johnson the brand's identity settled on AI infrastructure: Private Connectivity Fabric custom builds for hyperscalers and AI customers, plus the NaaS on-demand networking layer and the Lumen Connected Ecosystem launched in mid-2026.
What does Lumen own?
Lumen owns a national intercity fiber backbone, enterprise network and edge services, the NaaS platform, and residual copper mass-market operations. It sold its Quantum Fiber consumer business to AT&T in February 2026.
Is Lumen publicly traded?
Yes. It trades on the New York Stock Exchange under ticker LUMN.
What happened to CenturyLink?
CenturyLink renamed itself Lumen Technologies in 2020; the Lumen brand absorbed the company entirely, with CenturyLink and Level 3 retired as customer-facing names.
Did AT&T buy Lumen?
No. AT&T bought only Lumen's mass-market fiber-to-the-home business for $5.75 billion, completed February 2, 2026. Lumen remains an independent company.
Who is the CEO of Lumen?
Kate Johnson, president and CEO since November 2022, formerly a senior Microsoft executive.
How much revenue does Lumen generate?
$12.4 billion in FY2025, with Q4 adjusted EBITDA of $767 million at a 25.2 percent margin.
Where is Lumen headquartered?
Monroe, Louisiana, USA.
Debt restructuring: Years of declining revenue forced a 2024 debt restructuring and bankruptcy speculation, resolved by the AT&T proceeds that cut leverage to 3.8x.
Rural fund giveback: Returning FCC Rural Digital Opportunity Fund support in 2025 drew scrutiny over rural buildout commitments.
