Key Financial Performance
Revenue (Q4 2025) $291.6 million, reflecting a strong year-over-year growth of 20% and sequential growth of over 4%. The growth was driven by higher demand, strong execution, and contributions from all three business categories.
U.S. Revenue (Q4 2025) Increased by 31% year-over-year and 14% sequentially. Growth was led by strong demand in the U.S. market.
Non-U.S. Revenue (Q4 2025) Grew 12% year-over-year but declined 3% sequentially. The decline was attributed to recent ordering patterns among larger European customers.
Optical Networking Solutions Revenue (Q4 2025) Grew 33% year-over-year, driven by strong sales to cloud providers and enterprise customers. This was due to cloud providers expanding data center capacity and enterprises upgrading optical networks.
Access & Aggregation Revenue (Q4 2025) Increased by 9% year-over-year and 6% sequentially. Growth was supported by continued fiber access investment across U.S. and European operators.
Subscriber Solutions Revenue (Q4 2025) Grew 17% year-over-year and 3% sequentially. Growth was driven by demand for residential fiber CPE as customers connected more subscribers.
Non-GAAP Gross Margin (Q4 2025) Increased to 42.5%, up 44 basis points sequentially and 122 basis points year-over-year. The improvement was driven by scale efficiencies, product mix, and cost discipline.
Non-GAAP Operating Profits (Q4 2025) Rose to $18.8 million or 6.4% of revenue, up 103 basis points sequentially and 406 basis points year-over-year. This was due to improved scale and operating efficiency.
Non-GAAP EPS (Q4 2025) $0.16, compared to $0.05 in Q3 2025 and a loss of $0.02 a year ago. The improvement was partly due to the acquisition of shares from minority holders.
Operating Cash Flow (Q4 2025) $42.2 million, contributing to a full-year total of $129.8 million, which was a 25% increase compared to 2024. The increase was driven by improved working capital efficiency.

Revenue (Full Year 2025) $1.084 billion, reflecting a 17.5% year-over-year increase. Growth was driven by double-digit increases across all three revenue categories.
Non-GAAP Gross Margin (Full Year 2025) Expanded by approximately 90 basis points to 42.1%, due to increased scale, higher efficiency, and favorable product mix.
Non-GAAP Operating Margin (Full Year 2025) Increased to 4.8% from negative 0.3% in 2024, reflecting improved operational efficiency and revenue growth.

Key Q&A
Q:Can you talk about the demand picture in the U.S. and Europe, particularly on the optical and fiber-to-the-home sides, and the drivers of revenue growth?
A:The demand environment remains strong, with continued momentum from last year. Fiber-to-the-prem programs are progressing well, with new customers being added. In the fiber segment, inventory issues from last year have cleared, and new customer wins in the U.S. and Europe are driving growth. Drivers include Huawei replacement in Europe, increased bandwidth needs, and AI-driven demand. Enterprise and ICP carriers also showed positive momentum.
Q:Why is the operating margin outlook for the quarter set at a wide range of 4% to 8%?
A:The range is consistent with historical guidance and reflects tightening supply in memory and optics. However, these factors are not significantly impacting the guidance. Operating expenses are expected to remain in the low $100 million range, with gross margins at 42%-43%.
Q:Can you unpack the dynamics within the optical segment, particularly the contributions from hyperscale and AI data center cloud-related activities versus traditional SP and enterprise networking?
A:Both hyperscale/AI data center cloud-related activities and traditional enterprise networking contributed positively. ICPs performed stronger than historically seen, and this momentum is expected to continue.
Q:Are you seeing benefits from hyperscalers contracting with traditional SPs or Tier 2s for MOFN builds?
A:Yes, this activity is contributing positively to the carrier business, separate from the enterprise segment. It is part of an ongoing upgrade cycle adding momentum to the business.
Q:How did the U.S. fiber-to-the-home greenfield builds perform in Q4, and what is the outlook for 2026?
A:Q4 was solid, consistent with the year. BEAD funding is starting to flow, which is positive for planning and capital budgets. Fiber deployment will drive this year's activity, with equipment deployment expected next year.
Q:What is the status of noncore asset sales and building sales/leaseback activities?
A:Leaseback activity for the East Tower is on hold due to financial considerations. The North/South Tower is not under contract but has market activity. Noncore assets are being evaluated for value enhancement, with a reevaluation planned for the second half of the year.
Q:What are the key areas of excitement for 2026, particularly regarding equipment replacement in Europe and optical/geographical strength?
A:Enterprise is performing well, driven by multiple factors. Legislation in the EU to accelerate Huawei replacement is a positive catalyst, representing a near $1 billion annual opportunity. The focus on Huawei replacement is expected to benefit the business.
Q:What is driving the current inflection in Huawei replacement in the EU?
A:While EU directives are recommendations, some countries and carriers have stronger requirements. The ongoing legislative discussions discourage carriers from deploying Huawei in new regions, slowing their market presence. Pulling out Huawei entirely will take years, representing a $10 billion opportunity.
Q:How well positioned is the company to capture the $1 billion annual Huawei replacement opportunity in the EU?
A:The company is targeting products in its sweet spot, such as mid-mile, regional network optical, access, and aggregation. The TAM for these products in EMEA was approximately $850-$860 million in 2024, down from over $1 billion previously.
Q:What is the expected revenue distribution for European Tier 1 telcos in 2026, and how does it compare to last year?
A:Last year, revenue distribution was approximately 60% in the first half and 40% in the second half, primarily in the access and aggregation category. Efforts are being made to smooth out this distribution in 2026.
Q:Where are European telcos in their broadband deployment cycle?
A:Europe as a whole is in the early stages. Some countries, like the U.K., are in the middle stages, while others, like Germany, are in the early stages. Some carriers have not yet started.
Q:Review of Unclear Management Responses
A:Management avoided providing full-year revenue guidance, citing the short book-to-ship period as a reason. Additionally, they did not provide specific details on the expected impact of BEAD funding on equipment deployment or the exact timeline for noncore asset sales and building transactions.
