Cogent Communications Balances Growth Gains With Debt Risks

Cogent Communications ((CCOI)) has held its Q1 earnings call. Read on for the main highlights of the call.

Cogent Communications’ latest earnings call painted a mixed picture for investors. Management highlighted strong progress in high‑growth areas such as wavelength services, on‑net revenue and margins, along with steps toward deleveraging and refinancing. At the same time, the company acknowledged revenue softness, pressured EBITDA, elevated CapEx and a still‑heavy debt load weighing on the balance sheet.

Data Center Monetization Moves Toward Closing

Cogent reported a key milestone in monetizing former Sprint assets, saying it has signed a nonbinding LOI to sell 10 data centers. Due diligence is largely complete and management expects the transaction to close in early summer, with proceeds “substantially more” than $144 million earmarked to Cogent Communications Group, where they will be used to accelerate deleveraging efforts.

Wavelength Revenue and Customer Growth Accelerate

Wavelength services stood out as the breakout growth engine, with quarterly revenue of $13.6 million, up 90.8% year‑over‑year and 12.3% sequentially. Connections rose 71.2% year‑over‑year to 2,263, and Cogent now offers wavelength in 1,107 locations, with services sold into 581 sites to 492 customers and typical provisioning intervals around 30 days.

Rotation Toward Higher‑Margin On‑Net Services

On‑net revenue, including on‑net wavelength, reached $149.2 million, up 9.1% from a year ago and 1.9% sequentially, underscoring the shift in product mix. On‑net revenue increased to 62% of total company revenue versus 47% in Q3 2023 and 83% of Q1 sales were on‑net services, signaling a steady move into more profitable, owned‑network offerings.

Margins Improve on Cost Controls and Mix

Despite modest revenue contraction, profitability improved on a year‑over‑year basis. Adjusted EBITDA rose by $1.4 million and the adjusted EBITDA margin expanded by 150 basis points to 29.3%, while gross margin climbed to 46.1%, up 150 basis points, reflecting cost reductions and a richer mix of higher‑margin services.

IPv4 Leasing Delivers Steady Growth

IP leasing continued to provide a dependable revenue stream, generating $18 million in the quarter, up 4% sequentially and 25% from a year earlier. The average lease rate per IPv4 address was stable at $0.40 and the company controls about 37.8 million addresses, of which roughly 15 million are currently leased, leaving room for further monetization.

Network Traffic Growth and Diversified Customer Base

Core IP network traffic grew 14% year‑over‑year and 4% quarter‑over‑quarter, supporting the underlying demand story for bandwidth. Cogent now sells IP services in 1,929 data centers and connects directly to 7,630 networks, with the top 25 customers contributing only 16% of revenue, which limits concentration risk for investors.

Refinancing Progress Provides Capital Structure Path

Management signaled progress on its refinancing roadmap, announcing a verbal agreement with a majority of holders of the $600 million 2032 secured notes to amend the indenture. The changes would allow more flexibility to add pari‑passu or junior secured debt and use credit enhancements, paving the way to refinance the $750 million 2027 unsecured notes after the make‑whole period ends in mid‑2026.

Cogent Classic Business Shows Solid Organic Growth

While acquired Sprint revenues continue to erode, the legacy Cogent “classic” business is growing. Revenue run rate for this segment has climbed from $155 million at the time of the Sprint wireline close to $198 million this quarter, a 28% increase that reflects underlying organic demand for the company’s traditional IP transit and related services.

Overall Revenue Contraction Masks Internal Strength

Total company revenue slipped slightly to $239.2 million, down $1.3 million sequentially, or 0.6%, as Sprint‑related declines outweighed growth elsewhere. Management stressed that the negative growth in Q1 largely reflects the shrinking Sprint wireline base and that the pace of decline is moderating, positioning the business for cleaner growth comps over time.

EBITDA and SG&A Show Near‑Term Profit Pressure

Adjusted EBITDA fell sequentially by $6.6 million to $70.2 million as higher operating expenses hit results. SG&A increased by $7.1 million, or 11%, driven by seasonal payroll and CPI‑linked raises, payroll taxes, audit expenses and a sales meeting, creating a temporary drag on margins despite the positive structural mix shift.

Heavy Leverage Remains a Key Risk

The balance sheet remains a major investor focus, with gross debt at par, including IRU finance leases, around $2.4 billion and net debt roughly $2.0 billion after cash and amounts due from T‑Mobile. Management’s own metrics put net leverage close to 6.79x and gross leverage around 7.4x adjusted EBITDA, underscoring the importance of asset sales and refinancing.

Steep Decline in Sprint Revenue Base Continues

The inherited Sprint wireline portfolio continues to shrink sharply, reducing headline growth but also freeing capacity for higher‑margin business. The acquired revenue run rate dropped from $118 million at closing to $39 million this quarter, a 67% slide, with Sprint corporate revenue down from $39 million to just $8 million, about an 80% decline.

Wavelength Install Delays and Supply‑Chain Strains

Operationally, Cogent is wrestling with supply‑chain bottlenecks even as demand for wavelengths grows. Many customers delayed acceptance of new circuits due to their own power, optics and GPU constraints, while vendors implemented multiple price increases and extended delivery windows to 9–15 months, forcing Cogent to preorder gear and lifting near‑term capital needs.

CapEx Rises Above Prior Expectations

Capital expenditures reached $46.2 million in Q1 and management warned that capital intensity may exceed prior targets near term. Vendor price hikes and elongated lead times are driving higher spending as the company preorders equipment to secure future availability, complicating its earlier aim of keeping annual CapEx around the $100 million level in 2026.

Pricing Pressure and Sales Productivity Challenges

The company is facing lower unit pricing and sub‑par productivity in its sales force. The average price per megabit in the installed base declined to $0.12 from $0.14 sequentially and $0.20 a year ago, while sales rep productivity held at 4.1%, below the long‑term 4.8% average, though management indicated expectations for gradual improvement as mix and sales tools evolve.

Enterprise Revenue Drag from Sprint Exposure

Enterprise customers remain a small but challenged slice of the portfolio, accounting for 13.5% of total revenue. Enterprise revenue dropped 26% year‑over‑year and 5.7% sequentially, primarily because of declines in acquired Sprint enterprise off‑net revenue, reinforcing the near‑term headwind from the shrinking Sprint book.

Guidance and Long‑Term Targets Emphasize Growth and Deleveraging

Looking ahead, management reiterated multiyear goals of 6%–8% average annual revenue growth and about 200 basis points of EBITDA margin expansion per year, with expectations to surpass that pace in 2026 as mix shifts toward wavelengths and on‑net services. The company plans to complete refinancing of the 2027 notes after mid‑2026, while monetization of Sprint data centers and strong wavelength expansion, including a target to reach 25% of the North American long‑haul market from about 3% today, are central to its deleveraging and growth story.

Cogent’s earnings call underscored a company in transition, balancing bright spots in high‑growth, high‑margin services and network metrics against clear near‑term financial strains. For investors, the key questions are whether management can sustain wavelength and on‑net momentum, navigate supply‑chain and pricing pressures and execute its refinancing and asset monetization plans quickly enough to tame leverage and restore consistent top‑line and EBITDA growth.
