Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Revenue increased 82.1% in Q3 2025 and 115.6% for the nine months ended September 30, 2025, compared to the prior year periods. This was driven primarily by a 237.1% increase in CATV revenue (due to a major North American MSO network upgrade) and a 7.3% increase in Data Center revenue.
• Margin Expansion: Gross margin improved to 28.0% in Q3 2025 from 24.4% in Q3 2024, attributed to higher sales of high-margin products and cost reduction efforts.
• Operating Expenses: Total operating expenses rose 58.5% in Q3 2025, primarily due to increased personnel costs and R&D project expenditures to meet accelerated customer demand.
• Capital Structure: The company completed three "At-The-Market" (ATM) equity offerings in 2025, raising approximately $343 million in net proceeds. Additionally, the company retired the remaining $3.5 million of its 2026 Convertible Notes in July 2025.
• Inventory Build: Inventory increased significantly to $170.2 million (from $88.1 million at year-end 2024), contributing to a $84.6 million cash outflow in operating activities for the nine-month period.

Guidance, Outlook, and Risks

• Outlook: Management expects continued demand for 100G and 400G data center products through the end of 2025, driven by generative AI applications. Revenue from the Microsoft supply agreement is expected to increase in 2025.
• Liquidity: As of September 30, 2025, the company held $150.7 million in cash and restricted cash, with $43.8 million in unused borrowing capacity. The company maintains a full valuation allowance against deferred tax assets.
• Key Risks:
  • Geopolitical & Trade: Elevated tensions and tariffs between the U.S., China, and Taiwan (including a 20% reciprocal tariff on Taiwan imports) pose risks to supply chains and costs.
  • Customer Concentration: The top ten customers represented 97% of revenue for the nine months ended September 30, 2025.
  • Amazon Warrant: A warrant issued to an Amazon affiliate for up to 7.9 million shares (vesting based on $4 billion in purchases) is accounted for as a reduction of revenue.

Investor Verification Checklist

• Inventory Valuation: Verify the adequacy of inventory reserves given the rapid build-up to $170.2 million and the $5.4 million reserve adjustment recorded in the first nine months.
• Customer Concentration: Assess the stability of revenue given that 97% of sales come from the top ten customers, specifically the major North American MSO driving CATV growth.
• Capital Expenditure ROI: Review the timeline for the new factory in Ningbo, China, and the Sugar Land, Texas expansion to ensure capacity additions align with sustained demand.
• Trade Policy Impact: Monitor the status of U.S.-China and U.S.-Taiwan tariff negotiations and their potential impact on the cost of goods sold and supply chain logistics.
• Equity Dilution: Track the impact of the recent ATM offerings and the Amazon warrant on future earnings per share.
