Access earnings results, analyst expectations, report, slides, earnings call, and transcript.
Overview
The earnings call indicates negative financial performance, with declining revenues across key segments, a decrease in gross margin, and a negative adjusted EBITDA. Despite optimistic future guidance and growth opportunities in the second half of the year, the current financial health raises concerns. The Q&A section did not provide sufficient positive insights to offset these issues. Thus, the short-term stock price is likely to react negatively.
Key Financial Performance
Revenue $163 million, a decrease of 10% year-over-year, driven by lower sales in both Cloud & Edge (down 8%) and IP Optical Networks (down 14%).
Cloud & Edge Sales to Service Providers Declined approximately 5% year-over-year, primarily in the U.S. region across a number of smaller customers.
IP Optical Networks Sales Down 14% year-over-year, primarily due to lower sales in Asia Pacific and the completion of a long-term support and maintenance contract in Europe.
Enterprise Market Sales Declined approximately 6% year-over-year, with lower Cloud & Edge sales to U.S. government agencies partially offset by increased IP Optical business with international defense agencies.
Consolidated Gross Margin 45.8%, down 280 basis points year-over-year, primarily due to lower professional services revenue and higher service costs.
Adjusted EBITDA Negative $8 million, a $14 million decrease from the prior year, driven by lower revenues and gross margins.
Non-GAAP Operating Expenses $87 million, an increase of $1 million year-over-year, driven by FX headwinds of approximately $4 million, offset by expense savings.
Non-GAAP Net Loss $8 million, $4 million worse year-over-year, resulting in a non-GAAP diluted loss per share of $0.05.
IP Optical Networks Adjusted EBITDA Loss of $16 million, a $1.7 million higher loss than the prior year, driven by lower revenues.
Cloud & Edge Adjusted EBITDA $8 million, down $12 million year-over-year, primarily due to lower revenues and gross margins.

Risk or Challenges
Revenue Decline: First quarter revenue decreased by 10% year-over-year, driven by lower sales in both Cloud & Edge and IP Optical Networks segments. This decline was attributed to reduced sales to service providers in multiple regions, including the U.S. and Asia Pacific.
Gross Margin Pressure: Consolidated non-GAAP gross margin was abnormally low at 45.8%, down 280 basis points year-over-year. This was due to lower professional services revenue and higher service costs in anticipation of a second-half ramp-up.
Customer Timing Dynamics: First-half results were influenced by delays in customer deployment schedules, particularly with U.S. Tier 1 service providers like Verizon, impacting revenue and gross margins.
Geographic Sales Decline: Sales in Europe and Asia Pacific were lower year-over-year due to the completion of long-term contracts and reduced maintenance revenue. This was partially offset by stronger demand in India.
Operational Costs: Non-GAAP operating expenses increased by $1 million year-over-year due to foreign exchange headwinds, particularly from the strong Israeli shekel, which also impacted R&D costs.
Adjusted EBITDA Loss: Adjusted EBITDA for the quarter was negative $8 million, a $14 million decrease from the prior year, driven by lower revenues and gross margins.
Supply Chain and Resource Retention: The company is deliberately retaining key resources and expertise despite lower revenue in the first half, which impacts near-term profitability but is aimed at supporting future growth.
Economic and Market Uncertainty: The company faces challenges from economic uncertainties and market dynamics, including fluctuating demand across regions and sectors, which could impact future performance.

Key Q&A
Q:Can you explain the timing of Verizon's stronger performance in the second half of the year compared to the first half?
A:Bruce McClelland explained that there is no significant increase in revenue expected in the second quarter from Verizon. However, deployment rates are expected to progressively improve throughout the quarter. Growth in the second quarter will come from enterprise customers in North America, EMEA regions, and critical infrastructure deployments. In the second half of the year, growth is expected from Verizon, U.S. federal market, Asia Pacific region, and stronger performance in Europe.
Q:What is the correlation between rural data centers and regional service providers?
A:Bruce McClelland clarified that the correlation is not about regional service providers building data centers but leveraging network infrastructure for fiber-to-the-home and capacity expansions. This infrastructure connects to regional data centers, and funding like BEAD supports middle-mile capacity expansion.
Q:Can you elaborate on the agentic AI opportunity and how the company supports it?
A:Bruce McClelland described two aspects: (1) The launch of the Acumen platform, which uses agentic AI-driven operations to automate network management, leveraging analytics platforms and large language models. The commercial launch is planned with Optimum in the U.S. (2) The use of agentic AI in enterprises, where the company repurposes voice platforms to facilitate voice-driven connections to agentic applications, with initial deployments on AWS.
Q:Do you expect a meaningful difference in growth rates by segments in Q2?
A:Bruce McClelland stated that both segments are expected to grow in Q2, with the IP Optical segment likely growing more than the Cloud & Edge segment. Growth drivers include data center interconnect deployments, critical infrastructure projects, and backlog from bookings.
Q:What contributed to the year-over-year declines in Cloud & Edge and IP Optical in Q1?
A:For Cloud & Edge, the decline was not primarily due to Verizon but smaller projects with various service providers. For IP Optical, the decline was mainly in Europe and North America, with consistent performance in Asia Pacific, particularly India. European declines were attributed to project-based critical infrastructure customers.
Q:What is the materiality of the data center interconnect (DCI) opportunity relative to the IP Optical business?
A:Bruce McClelland explained that DCI was not a focus area 3-4 years ago but has become a growth area with new products like the 2700 series and optical transport platform. While currently small, the company sees strong growth potential and is improving its go-to-market strategy to capture opportunities in the DCI market.
Q:Has visibility into the sustainability of India CapEx improved since last quarter?
A:Bruce McClelland confirmed improved visibility, with the India market remaining strong and contributing positively to Q1 revenue. He also noted robust enterprise market opportunities and better visibility in U.S. federal programs compared to the previous quarter.
Q:Review of Unclear Management Responses
A:No questions were identified where management avoided giving a direct answer or lacked clarity in their responses.
