StockStory’s Take

Cogent’s first quarter results were met with a significant negative market reaction, as the company’s revenue fell short of Wall Street expectations and declined year over year. Management attributed the underperformance primarily to ongoing declines in the acquired Sprint wireline customer base, particularly among corporate and enterprise segments. CEO Dave Schaeffer acknowledged these pressures, noting that “the decline in revenues from acquired Sprint customers is moderating,” while the core Cogent on-net business showed resilience. The quarter also saw higher seasonal expenses and persistent supply chain cost pressures.

Looking forward, management is focusing on several levers to support future growth, including the monetization of former Sprint data centers, ongoing cost reduction, and a continued emphasis on on-net services and wavelength expansion. Schaeffer highlighted the company’s expectation for long-term annual revenue growth of 6% to 8% and EBITDA margin expansion, but cautioned that equipment price inflation and customer-side delays in wavelength acceptance could present near-term challenges. The team reiterated its commitment to deleveraging and completing key refinancing milestones in the coming quarters.

Key Insights from Management’s Remarks

Management pointed to a shifting revenue mix, cost discipline, and infrastructure monetization as key themes impacting the quarter’s results and future strategy.

• Sprint wireline decline: The ongoing contraction in the acquired Sprint wireline customer base continued to weigh on total revenue, especially in the less profitable off-net and enterprise segments. Management stated that Sprint-related revenues now represent only 16% of total revenues, down from 42% at acquisition, and the majority of the revenue loss was isolated to this customer set.

• On-net and wavelength focus: Cogent’s core on-net business, which refers to network connections directly served by Cogent’s infrastructure, grew both sequentially and year over year. Management emphasized that 83% of sales in the quarter were on-net, and on-net revenues—including wavelength services—now constitute 62% of total revenues. Wavelength revenues, which are high-speed data connections sold to customers, rose nearly 91% year over year, reflecting demand from hyperscalers and AI-driven workloads.

• Cost containment and margin improvement: Despite revenue headwinds, management credited margin gains to ongoing cost reductions and a shift to more profitable products. Gross margin rose 150 basis points year over year, and adjusted EBITDA margin was supported by lower integration and noncore costs, even as seasonal SG&A expenses were higher.

• Data center monetization: The company advanced its plan to monetize former Sprint data center assets, entering a non-binding agreement to sell 10 facilities, with closing targeted for early summer. Schaeffer said proceeds would primarily be used for debt reduction, supporting Cogent’s deleveraging goal.

• Vendor and supply chain pressures: Management discussed unexpected increases in equipment prices driven by supply chain constraints, particularly for optical transport and networking equipment. These cost pressures impacted capital spending and may persist in the near term, though management believes they are not permanent.

Drivers of Future Performance

Cogent’s forward outlook is shaped by data center asset sales, margin expansion from cost initiatives, and efforts to capture long-haul wavelength market share.

• Data center sales and deleveraging: The successful sale of 10 Sprint-acquired data centers is expected to generate significant proceeds for debt paydown. Management believes this will improve balance sheet flexibility and reduce interest costs, with further data center divestitures under consideration for additional deleveraging.

• Wavelength and on-net growth: The company aims to capture 25% of the North American intercity long-haul wavelength market, up from the current 3%. However, management cautions that customer-side delays—such as data center readiness and equipment availability—could affect the timing of installs. Hyperscaler and AI demand remain important long-term drivers, and management expects these trends to accelerate once infrastructure constraints ease.

• Margin expansion and cost control: Cogent continues to target multiyear EBITDA margin expansion of approximately 200 basis points annually, driven by ongoing synergies from the Sprint integration and further migration away from low-margin contracts. Seasonal expense normalization and the eventual roll-off of integration costs are expected to support profit improvement.

Catalysts in Upcoming Quarters

In the coming quarters, our team will watch (1) progress on closing and monetizing additional Sprint-acquired data centers, (2) evidence of sustained on-net and wavelength revenue growth despite ongoing Sprint customer attrition, and (3) normalization of equipment costs and supply chain pressures that have affected capital spending. The pace of deleveraging and refinancing will also serve as important markers of execution.

Cogent currently trades at $16.15, down from $23.16 just before the earnings. In the wake of this quarter, is it a buy or sell? See for yourself in our full research report (it’s free).
