Lumen Posts $2.72 Billion Q3 Revenue, Bets $13.5 Billion on AI Fiber

Lumen Technologies reported third-quarter revenue of $2.72 billion, with strategic network services growing 10% year over year to $1.28 billion — not enough to stop a 4.5% decline in total business revenue, which fell to $2.35 billion. The carrier reaffirmed its full-year guidance and said it will tear out copper faster than planned. Whether the arithmetic holds together is a separate question, and the company's own disclosures leave parts of it unanswered.

Strategic revenue now makes up 55% of business revenue, up from 48% a year earlier, Chief Financial Officer Chris Stansbury said. That share shift is real, but it partly reflects the denominator shrinking: legacy decline continues even as the new business scales.

What is driving the growth?

CEO Kate Johnson tied demand to artificial intelligence workloads and customers seeking flexible connections. She offered three data points:

• Strategic sales climbed 30% year over year.
• Strategic wavelength sales rose 22% from the second quarter.
• Lumen signed an additional $700 million in private connectivity fabric (PCF) deals, lifting cumulative PCF business above $13.5 billion.

Johnson described PCF as private network interconnects that hyperscalers use for AI model training. She said Lumen beat its 2026 target of deploying 5 million new fiber miles funded by signed PCF deals by more than two months, and that customers have not slowed their timelines — hyperscalers are pressing the company to move faster. A claim of sustained hyperscaler urgency deserves scrutiny; the PCF backlog is signed, but delivery schedules and renewal terms remain the company's own reporting.

Traffic on Lumen's global public internet backbone grew 20% since the start of the year. AI traffic remains a small slice of that total, yet it has expanded more than 1,000% since April — a figure Johnson read as rising enterprise interest in AI inference. A 1,000% rise on a small base says direction, not scale, and Lumen did not quantify the base.

How large is the digital business really?

Digital revenue increased 86.7% year over year to $56 million, lifted by network-as-a-service offerings and the Alkira acquisition. Excluding Alkira, Stansbury said digital revenue still grew at a "very healthy double-digit" rate — without a precise figure. The omission matters for anyone modeling the organic base.

Lumen has merged dedicated internet access with its on-demand service into Lumen Intelligent Internet, a combined business representing more than $1 billion in revenue, over 100,000 installed ports and more than 25,000 customers. Stansbury said that revenue base moves into the digital reporting category starting in 2027, with a pro forma digital revenue figure to follow. Reporting changes arriving alongside growth claims warrant caution until the restated numbers appear.

The company also reported more than 4,000 network-as-a-service customers, with active customers up 24% quarter over quarter, active ports up 38% and active services up 35%. Lumen plans to stop reporting these adoption metrics and report financial performance instead — a shift that will make trend-tracking harder, not easier, in the near term.

What did the quarter earn?

Third-quarter adjusted EBITDA, excluding special items, came in at $715 million — above the company's own expectation, primarily because operating expenses ran lower than planned. Capital expenditures, excluding special items, totaled $796 million.

Free cash flow, excluding special items, was negative $76 million for the quarter and negative $1 billion year to date. Those figures include cash tax payments of $75 million and $321 million respectively, tied to the Mass Markets Fiber-to-the-Home divestiture and excluded from guidance. The divestiture is doing some work here; the underlying free cash flow picture is less severe than the headline negative suggests, but the taxes are real cash out the door.

Lumen reaffirmed its full-year outlook: adjusted EBITDA of $3.1 billion to $3.3 billion, capital expenditures of $3.2 billion to $3.4 billion, and free cash flow of $1.9 billion to $2.1 billion excluding special items and the divestiture-related tax payments.

What does the copper exit change?

Lumen will accelerate copper decommissioning in Iowa, Florida, Nevada and Utah — four states covering roughly 25% of its copper footprint, on top of modernization already underway elsewhere. At current copper prices, the company expects $1 billion to $1.5 billion in pretax net proceeds from recovered copper across its footprint over five years. That estimate excludes operating expense savings and depends on customer migration, regulatory approvals, recovery costs and market conditions — four dependencies, each capable of moving the number.

Stansbury said Lumen spends roughly $200 million to $300 million annually in capital expenditures just to maintain copper networks. A substantial portion of the impact from the first four states should begin in the latter part of 2027, he said, while acknowledging that revenue losses and cost savings may not arrive at the same time — a timing gap that will pressure interim margins.

Year to date, the strategic portfolio's average direct margin exceeded 80%, versus roughly 65% for legacy services, a difference Stansbury attributed to lower costs to serve and the scalability of digital services. He said Lumen still models a return to total business revenue growth in 2028, even with the faster copper exit, with Alkira largely offsetting the transition's effect in that forecast.

Every promise in this plan — the 2028 growth inflection, the copper proceeds, the digital reclassification — carries a condition the company itself listed. Lumen has the contracts; it now has to deliver on the calendar.
