Lumen Technologies, Inc.

Overview

Lumen Technologies, Inc. is a digital networking and communications services company that connects businesses, people, data, and applications. Its offerings include network connectivity, private connectivity, edge and digital services, and cybersecurity. In its FY2025 reporting, Lumen described two segments: Business, serving domestic and international customers, and Mass Markets, serving domestic customers. The company completed the sale of its fiber-to-the-home business in 11 states to AT&T in February 2026, after the FY2025 reporting period.[1]+2

Lumen describes its mission as “Streamlining your innovation,” with a focus on connecting people, data, and applications quickly, securely, and effortlessly. Its network spans North America and Asia Pacific; at year-end 2025, it reported more than 340,000 route miles of fiber optic cable globally. For FY2025, operating revenue was $12.402 billion, and the company had approximately 24,000 employees worldwide at year-end.[4]+3 [1]+6

Products & services

Lumen’s strategic networking portfolio includes dark fiber and conduit for customers building high-bandwidth private networks; optical wavelength services that provide scalable, end-to-end Ethernet connectivity between sites and cloud environments; global IP access; Ethernet services for point-to-point and multipoint data transmission; and VPNs that carry voice, video and data over private networks. Lumen’s fiber plant spans more than 340,000 route miles, according to its 2025 Form 10-K.[8]+5

Digital and managed services include Network-as-a-Service (NaaS) and Edge Fabric; SD-WAN, offered as managed or co-managed services; Edge Cloud Services for access to public and private cloud and workload movement between cloud environments; and managed security, including DDoS mitigation, firewalls, threat intelligence and security consulting. Lumen also offers VoIP services such as SIP trunking and hosted cloud voice, as well as unified communications and collaboration services.[14]+5 Alkira adds a cloud-native, carrier-agnostic platform for configuring and operating connectivity across hybrid and multicloud environments.[20]

The company groups offerings into strategic and legacy categories rather than disclosing revenue for each named product. In Q2 2026, strategic services accounted for approximately 53% of Business revenue. Its reported product categories also include Fiber Broadband, Other Broadband, and Voice and Other; Fiber Broadband serves residential and small-business customers over Lumen’s fiber network.[21]+2 [8]+15

Geographic presence

Lumen Technologies’ network footprint is concentrated in North America, where it reported more than 340,000 route miles of fiber at year-end 2025. Its terrestrial long-haul fiber also extends across Asia Pacific and connects with metro networks; the company reported approximately 163,000 on-net buildings globally. Its broader connectivity reach includes owned, leased-access, and third-party carrier network segments, so service availability in a country does not necessarily indicate Lumen-owned facilities there.[9]+2

Lumen says it owns or leases administrative offices in major U.S. and international metropolitan areas, without enumerating them in its 2025 filing; its principal executive offices are in Monroe, Louisiana.[25][26] The 2025 filing does not provide revenue by country or region, or a geographic breakdown of employees; its segment reporting is based on customer classification rather than geography.[27] [9]+5

Business segments

In 2026, Lumen Technologies reports one operating and reportable segment: its consolidated business. Management began assessing performance on a consolidated basis and no longer regularly reviews separate financial information for individual business components. For the six months ended June 30, 2026, this segment generated $5.704 billion in revenue, equal to 100% of reported consolidated revenue; the filing does not provide a current revenue split for the former segments.[28]+2

The latest full-year two-segment breakdown is for 2025 and is historical rather than Lumen’s current reporting structure. Business generated $9.895 billion, approximately 79.8% of $12.402 billion in operating revenue, and served enterprise and wholesale customers through Large Enterprise, Mid-Market Enterprise, Public Sector, Wholesale, and International and Other channels. Mass Markets generated $2.507 billion, approximately 20.2%; its reported product categories were Fiber Broadband, Other Broadband, and Voice and Other.[31]+2 [28]+5

Company history

Lumen’s origins trace to 1930, when Clarke and Marie Williams purchased the Oak Ridge Telephone Company in Louisiana; Clarke Williams is identified as the company’s founder. Lumen’s filings state that the company was incorporated in Louisiana in 1968.[34]+2 In 1999, Century Telephone Enterprises changed its name to CenturyTel, Inc.[37]

CenturyTel completed its merger with EMBARQ in 2009 and adopted the CenturyLink identity. It then completed mergers with Qwest in 2011 and Savvis in the same year, followed by its acquisition of Level 3 Communications in 2017.[38]+3 In 2018, Jeff Storey succeeded Glen Post as CEO.[42]

The company rebranded as Lumen Technologies in 2020. In 2022, Kate Johnson became CEO, and Lumen completed the sale of its local incumbent-carrier operations in 20 states to Brightspeed.[43]+2 In 2025, Lumen announced the sale of its consumer fiber-to-the-home business to AT&T; the sale was completed in February 2026.[46][47] [36]+13
