• Like **AT&T or Verizon**, but largely for businesses, governments, and other internet companies rather than individual consumers.
• **Kinder Morgan** for digital data, owning and operating a vast fiber optic network that serves as a backbone for businesses and the internet.

• Network Connectivity Services: Provides high-speed internet, private networks (e.g., MPLS, SD-WAN), and dedicated fiber connections for businesses and government clients.

Lumen Technologies (symbol: LUMN) primarily sells its services to other companies, rather than directly to individuals. However, due to the broad and diversified nature of its client base and the fact that no single customer accounts for more than 10% of its consolidated revenues, Lumen does not disclose specific individual "major customer companies" by name in its public filings. Therefore, instead of listing specific named companies, we can describe the primary categories of organizations that Lumen serves:

• Enterprise Customers: This segment includes a wide array of large and mid-sized businesses across diverse industries such as financial services, healthcare, retail, manufacturing, technology, and media. These companies rely on Lumen for critical services like network connectivity (fiber, IP VPN), cloud connectivity, managed services, security solutions, and unified communications.
• Wholesale Customers: This category comprises other telecommunications carriers, internet service providers (ISPs), content providers, and data center operators. Lumen provides these companies with network capacity, dark fiber, transport services, and other infrastructure solutions that they then use to serve their own end customers.
• Government Customers: Lumen provides secure network services, voice, data, and IT solutions to various federal, state, and local government agencies. This includes mission-critical communications infrastructure and managed services tailored for public sector needs, supporting essential government operations.

Lumen Technologies relies on several major suppliers for its network infrastructure, equipment, and services. Key suppliers include:

• Cisco Systems (CSCO)
• Nokia (NOK)
• Ciena (CIEN)
• Corning (GLW)

The increasing expansion of hyperscale cloud providers (e.g., AWS, Microsoft Azure, Google Cloud) into global network services and direct enterprise connectivity. These providers are building extensive global fiber networks, points of presence, and edge computing facilities, offering direct connection services (e.g., AWS Direct Connect, Azure ExpressRoute, Google Cloud Interconnect) and integrated network-as-a-service functionalities as part of their cloud ecosystems.

This development threatens Lumen by:

• Disintermediation: As enterprises migrate more applications and data to the cloud, they increasingly procure core networking services and connectivity directly from the hyperscalers, potentially bypassing traditional telecom carriers for crucial segments of their network traffic and management.
• Shifting Control and Value: Hyperscalers are aiming to own a larger share of the enterprise IT and network spend, moving the control point and strategic value away from traditional network providers like Lumen, even for hybrid and multi-cloud environments.
• Competitive Pressure: While Lumen partners with hyperscalers, the cloud providers' growing networking capabilities represent a competitive force for certain enterprise connectivity and managed network services that Lumen traditionally provides.

Lumen Technologies (symbol: LUMN) offers a range of products and services, targeting various addressable markets. The size of these markets, along with their respective regions, is detailed below:

• Network-as-a-Service (NaaS) / Private Connectivity Fabric (PCF): Lumen is positioned in a serviceable addressable market (SAM) for NaaS across Mid-Market and Large Enterprise channels, estimated to grow from $10-15 billion in 2022 to $25-35 billion by 2027. This market is primarily within North America, considering Lumen's focus on its domestic enterprise and global operations. Additionally, Lumen is targeting a new $15 billion Total Addressable Market (TAM) in cloud networking through initiatives like direct fiber access to cloud providers, which is likely a global market opportunity given the nature of cloud services.
• Cloud Voice / Unified Communications and Collaboration (UC&C): The total addressable market (TAM) for cloud voice, where Lumen offers its Cloud Communications Platform (LCC), is estimated at $47 billion. This is a global market.
• Mass Markets Fiber (Quantum Fiber): In 2022, Lumen had approximately 21 million addressable home and small business locations in its 16-state region within the U.S. for its Quantum Fiber service. However, it is important to note that Lumen announced the sale of approximately 95% of its Mass Markets consumer fiber business, including Quantum Fiber, in eleven states to AT&T for $5.75 billion, a deal expected to close in early 2026. Lumen will retain assets serving enterprise and wholesale fiber customers in all geographies, and its existing copper network for consumer customers. Therefore, the addressable market for Lumen in this segment is significantly reduced after the divestiture.
• Dark Fiber Network Operators: Lumen holds an estimated 17.6% market share in the Dark Fiber Network Operators industry within the U.S.. A specific total market size was not identified in the search results.
• Security Services (e.g., DDoS, SASE): A relevant U.S. business Telco market for security was estimated at $135 billion in 2023, with a 15% CAGR. While a specific addressable market for Lumen's distinct security offerings was not provided, they operate within this broader market.
• Edge Cloud & IT Agility and Managed Services: Specific addressable market sizes for these services were not explicitly identified in the provided search results.

Lumen Technologies (symbol: LUMN) anticipates future revenue growth over the next two to three years will be driven by several strategic initiatives focusing on its enterprise business and advanced network capabilities.

1. Expansion of Private Connectivity Fabric (PCF) and AI-Ready Network Infrastructure: Lumen is prioritizing its enterprise sector, driven by the increasing demand for robust network infrastructure to support artificial intelligence (AI) workloads. The company has secured significant deals for its Private Connectivity Fabric (PCF) offering, including $8.5 billion in 2024 with major hyperscalers and an additional $1 billion in new PCF deals recently, bringing the total awarded deal value beyond $10 billion. This expansion is crucial for building the backbone of the AI economy and facilitating hyperscale cloud deployments.

2. Growth of Network-as-a-Service (NaaS) and Digital Services: Lumen is actively pushing for the adoption of its Network-as-a-Service (NaaS) platform and other digital offerings to drive high-value digital revenue growth. The company aims to generate between $500 million and $600 million in incremental digital revenue by the end of 2028, primarily by scaling its digital ecosystem and accelerating NaaS adoption. Lumen is developing NaaS capabilities to provide more agile and on-demand network solutions.

3. Strategic Partnerships and the "Connected Ecosystem" Strategy: Lumen is leveraging strategic partnerships to enhance its network capabilities and expand its market reach. Its "Connected Ecosystem" strategy focuses on forming high-impact partnerships, such as those with Google Cloud (April 2025) for dedicated fiber access, Meta (October 2024) to boost AI network capacity, and Palantir. This strategy aims to embed Lumen's network solutions directly into partner marketplaces, accelerating adoption and giving Lumen's connectivity a better position within other companies' cloud and data offerings. The launch of "Internet On-Demand (IOD) off-net" also significantly expands Lumen's addressable market by enabling it to sell digital services even without owning the last-mile connection.

4. Growth in the "Grow" Product Portfolio (Dark Fiber and IP): Lumen's "Grow" product segment, which includes dark fiber and IP services, is a key driver for its North American enterprise revenue. This segment saw a 10.5% year-over-year increase in revenue in a recent quarter, with "Grow" now comprising 50% of North American enterprise revenue, up from 35.5% three years ago. This shift highlights Lumen's successful pivot away from legacy telecom services towards higher-growth, modern network solutions.
