Management Comments

• "We successfully delivered revenue, gross margin, and non-GAAP EPS in line with our expectations." Dr. Thompson Lin, Founder, President and CEO.
• "We continued to see strong demand in our CATV business, driven by the continued ramp in orders for our 1.8 GHz amplifier products." Dr. Thompson Lin, Founder, President and CEO.
• "We believe that the appeal of our amplifiers and QuantumLinkTM software is broad-based, which was evident by the continued momentum we saw with our largest customer as well as new customers during the quarter, and which led to the highest quarterly CATV revenue in our Companys history."

Industry Context

The strong demand in the CATV business, particularly for 1.8 GHz amplifier products, reflects ongoing investment in broadband infrastructure upgrades. The progress in 800G product qualification and the focus on increasing production capacity for AI-focused datacenter transceivers align with the booming demand for high-speed optical interconnects driven by artificial intelligence and cloud computing expansion. The company's strategic emphasis on U.S. domestic production for these advanced transceivers positions it to potentially benefit from national security and supply chain resilience initiatives.

Stakeholder Impact

• Shareholders: Positive impact from strong revenue growth, improved non-GAAP net loss, record CATV performance, and positive future outlook for 800G products. Potential for increased value as 800G qualifications complete and shipments begin.
• Customers: Benefit from increased production capacity for 800G transceivers and continued strong supply of CATV products. Datacenter customers experienced some shipping delays in Q3.
• Employees: Continued investment in production capacity in the U.S. and Taiwan suggests stable or growing employment opportunities.
• Suppliers: Increased production capacity implies continued or increased demand for components and materials.

Next Steps

• Produce meaningful shipments of 800G products in the fourth quarter of 2025.
• Continue increasing production capacity in U.S. and Taiwan locations.
• Exit 2025 with a production capacity of approximately 100,000 units of 800G transceivers per month.
• Host a conference call and webcast on November 6, 2025, to discuss Q3 2025 results and Q4 2025 outlook.

Key Dates

Recommendation

The company delivered strong revenue growth and record CATV performance, with an improving non-GAAP net loss. The progress on 800G product qualification and the ambitious production capacity targets for AI-focused transceivers present significant future growth potential. However, the datacenter segment slightly missed expectations due to shipping delays, and the company continues to report a GAAP net loss. While the outlook is positive, the execution risk associated with ramping up 800G shipments and the ongoing GAAP losses suggest a 'hold' recommendation. Investors should monitor the successful qualification and ramp of 800G products and the company's ability to achieve profitability.
