SEC filingRevenue surged 82% YoY to $118.6M in Q3 2025, driven by CATV recovery and data center growth, with gross margin expanding to 28.0%.
For the three months ended September 30, 2025, Applied Optoelectronics reported net revenue of $118.6 million, an 82.1% increase from $65.2 million in the same period last year. The growth was primarily driven by a surge in CATV revenue and steady data center demand. Gross profit climbed 109.0% to $33.3 million, with gross margin expanding 360 basis points to 28.0%, reflecting a favorable product mix and cost reduction initiatives. Operating expenses rose 58.5% to $51.5 million, largely due to increased R&D and sales & marketing investments to support new product development and customer acquisition. However, operating loss improved as a percentage of revenue from -25.4% to -15.3%. Net loss remained nearly flat at $17.9 million, compared to $17.8 million in the prior year quarter.
CATV was the standout segment, with revenue skyrocketing 237.1% to $70.6 million, representing 59.5% of total revenue (up from 32.2% a year ago). The increase was attributed to the beginning of a major network upgrade project by a large North American MSO. Data center revenue grew 7.3% to $43.9 million, accounting for 37.0% of revenue. The company saw increased orders for 100G and 400G products from existing customers and initial orders from a new hyperscale customer, linked to AI-driven capacity expansion. Telecom revenue rose 33.7% to $3.7 million, benefiting from 5G deployments. Other revenue declined 23.9% to $0.4 million. Customer concentration remained high, with the top ten customers representing 98% of revenue in Q3 2025.
Management expects continued momentum in data center products through the end of 2025, supported by a supply agreement with Microsoft and growing demand for AI-enabled processing capacity. The CATV segment is anticipated to benefit further from the ongoing MSO upgrade project. The company is actively monitoring tariff developments and optimizing operations to mitigate potential impacts. With $150.7 million in cash and equivalents and $43.8 million in unused borrowing capacity, liquidity appears sufficient for planned investments. However, operating cash flow remained negative at $144.9 million for the nine-month period due to working capital buildup. No specific numerical guidance was provided, but the outlook suggests continued revenue growth and margin improvement.
Cash and equivalents stood at $136.96M as of September 30, 2025, up from $67.43M at December 31, 2024, reflecting proceeds from common stock offerings and debt activities. Restricted cash was $13.76M. Total debt comprised $27.98M in short-term notes payable and $130.12M in convertible senior notes (2030 Notes net carrying amount), resulting in total debt of $158.10M, a slight decrease from $161.18M at year-end. Shareholders' equity grew to $559.09M from $229.11M, driven by a $342.56M net public offering. Inventory increased substantially to $170.21M from $88.14M, primarily in raw materials and work-in-process.
The notes disclose operating lease commitments of $49.29M in undiscounted payments, with $43.02M present value. A new lease in Sugar Land, Texas for 209,665 sq ft will commence in Q1 2026 with additional $21.9M in lease payments. No other material purchase commitments (e.g., supply agreements) were disclosed. The company has $43.8M in unused borrowing capacity under revolving credit facilities.
No share repurchase programs or dividends were authorized or paid. The company retired the remaining $3.5M principal of the 2026 Notes in July 2025 via stock exchange. Net debt decreased modestly by $3.08M. Capital expenditure details are not in the notes section, but the balance sheet shows property, plant and equipment net of $310.30M versus $219.24M at year-end, indicating significant investment.
The company operates as a single reportable segment, with the CODM focusing on consolidated net loss for resource allocation. However, Note 3 reveals product-line revenue: CATV contributed $70.6M (59.5% of Q3 2025 sales), Data Center $43.9M (37.0%), Telecom $3.7M (3.2%), and Other $0.4M (0.3%). Geographically, manufacturing revenue derived 1.4% from the U.S., 36.9% from Taiwan, and 61.7% from China for Q3 2025. Long-lived assets were split across these regions similarly.
