Access earnings results, analyst expectations, report, slides, earnings call, and transcript.
Overview
The earnings call provides a mixed picture: strong financial metrics and optimistic guidance are offset by delays in government projects and Verizon's restructuring impact. The Q&A session reveals uncertainties, particularly regarding government funding and customer restructuring. While there are positive developments like new bookings and potential growth in India, the lack of clarity on key issues tempers enthusiasm, suggesting a neutral stock price movement.
Key Financial Performance
Revenue for Q4 2025 $227 million, a decrease of 10% from the prior year. The decline was attributed to customer and project delays, including a $10 million reduction in sales to U.S. federal agencies and a challenging comparison to a record quarter with Verizon in Q4 2024.
Full Year 2025 Revenue $845 million, an increase of 1% year-over-year. Excluding sales to Russia in 2024, sales to all other customers increased 4% in 2025. Growth was driven by increased sales to global service providers (up 5%) and enterprise customers (up 2%), while sales to government and defense declined 23%.
Sales in India for Q4 2025 Increased 28% year-over-year due to deployments with Bharti and new rural broadband projects. For the full year, sales in India grew more than 40%, exceeding $100 million.
Adjusted EBITDA for Q4 2025 $40 million, $2 million below guidance due to lower sales, offset by reduced operational expenses, primarily related to lower employee variable compensation.
Full Year 2025 Adjusted EBITDA $107 million, a decrease of $12 million from the prior year, driven by lower gross margin.
Non-GAAP Gross Margin for Q4 2025 55.4%, down 270 basis points year-over-year due to lower software revenue, higher professional services revenue, and geographic mix with strong performance in India.
Full Year 2025 Non-GAAP Gross Margin 52.3%, down 355 basis points from the prior year, driven by higher sales in India and increased services revenue.
Cloud and Edge Segment Revenue for Q4 2025 $142 million, a decrease of 14% year-over-year. The decline was attributed to a record Q4 2024 and lower revenue in the current quarter despite record bookings.
IP Optical Networks Revenue for Q4 2025 $85 million, a 2% decrease year-over-year. The decline was due to project delays in North America and lower sales in EMEA, offset by growth in India.
Net Income for Q4 2025 $106 million, a $78 million improvement year-over-year, driven by a $90 million deferred tax benefit related to the ECI investment.
Full Year 2025 Non-GAAP Net Income $118 million, up $74 million from the prior year, driven by the tax benefit.
Cash Flow from Operations for Q4 2025 $29 million, resulting in a closing cash balance of $98 million.
Full Year 2025 Cash Flow from Operations $51 million, with total CapEx spend of $15 million and an additional $10 million for a new Israeli facility.

Key Q&A
Q:Can you provide more details on the $50 million in new Cloud & Edge bookings? Are these from new customers or existing ones like Verizon?
A:The $50 million in new bookings are non-Verizon and come from about a dozen different customers. These bookings include a mix of reasonably large deals and smaller single-digit million-dollar deals. About 25% of the revenue from these bookings was shipped in Q4, with the rest expected to be realized over the next 15 months.
Q:Are any of the dozen customers in the new bookings large enough to eventually be like Verizon or Brightspeed?
A:Yes, some of the customers have the potential to grow to that scale.
Q:Can you provide more color on the delays you are seeing across government and U.S. service providers?
A:The delays fall into two categories: 1) Deployment delays with existing backlog, such as professional service programs tied to customer restructuring, which immediately impacted revenue. 2) Year-end budget issues, such as delays in BEAD funding approvals, which are awaiting final government contracts. These delays have pushed revenue out of the quarter.
Q:Should we expect sequential growth every quarter this year given the low starting point in Q1?
A:Yes, the company is profiling sequential growth throughout the year, despite a slow start in Q1. Factors include Verizon's restructuring, U.S. federal government spending ramp-up, and cautious projections for India due to fiscal year-end budget finalizations.
Q:How does the $50 million in orders relate to the total opportunity at those customers?
A:The $50 million represents 12- to 15-month horizon programs and does not include long-term commitments like Verizon's three-year rollout. The total addressable market for modernization is large, with approximately 20 million POT lines in the U.S. Verizon's current program covers about one-third of their network, with significant opportunities remaining.
Q:What is the impact of Verizon's restructuring and CapEx cuts on your business?
A:The company is cautious due to uncertainty around Verizon's plans following their merger with Frontier. While there is significant growth potential, the restructuring and macro changes have created near-term uncertainty.
Q:What are your thoughts on BEAD funding delays and its impact?
A:The company is optimistic about BEAD funding as a growth opportunity, expecting significant contributions in the second half of the year. However, delays in approvals have pushed expected revenue from Q4 into later quarters.
Q:What are your updated thoughts on down-market opportunities for voice modernization?
A:Most activity is in Tier 2 operators who are committed to lowering network operating costs. Smaller operators show varied approaches, with some using voice as a lead service to sell more fiber and others maintaining existing networks without significant investment.
Q:What is the typical decline rate for your legacy maintenance business?
A:The decline is steady, with a few million dollars of erosion annually. In some cases, prices have been raised, and the IP and Optical business maintenance revenue is growing.
Q:What are the main use cases for your packet optical platforms in the next 18 months?
A:The focus is on broadband aggregation and backhaul, with differentiation in integrating IP networks with optical networks. Growth in North America and India has been driven by IP/MPLS portfolio expansion.
Q:What is the status of the enterprise SBC market?
A:The enterprise SBC market remains profitable, with innovation focused on cloud-native platforms. The company has seen significant wins, including partnerships with AWS, and SBC sales were a major growth area in Q4.
Q:What is the status of federal segment revenue and delays?
A:Federal segment revenue was down $10 million in Q4 compared to the previous year. Delays were evenly split between Cloud & Edge and IP Optical, with some revenue expected to be realized in Q1 and subsequent quarters.
Q:What is the status of Acumen platform adoption and customer feedback?
A:The company is in the deployment phase with a lead customer and has about a dozen POCs lined up. Customers are evaluating the platform's OpEx savings before making long-term commitments. Revenue from Acumen is expected to grow in the second half of the year.
Q:Review of Unclear Management Responses
A:Management avoided providing specific numbers for the total addressable market for modernization, citing variability in customer approaches. They also did not provide clear timelines for when delayed projects, such as those impacted by BEAD funding or customer budget issues, would be fully realized. Additionally, there was a lack of clarity on the exact impact of Verizon's restructuring and CapEx cuts on future revenue.
