Q&A highlights

How do tightening lead times impact customer requalifications, especially for securing capacity for 2027, and what is the timing for analog product requalifications?

Tightening lead times encourage customers to qualify new products, especially with long-term supply guarantees. Qualification processes for internal factories are progressing well, but full ramp-up will take time, with significant utilization improvement expected in 2027-2028 for newer fabs.

“During the constrained supply market situation, customers are always more willing for qualifications, especially with the guarantee of a long-term supply, right? So definitely, it's beneficial.”

Detailed narrative

AI Infrastructure and 800-Volt Opportunity

Diodes sees AI as a broad ecosystem, not limited to AI servers, with significant opportunities in power supply units, battery backup units, networking, and optical modules. The company is well-positioned for the 800-volt platform with silicon carbide MOSFETs, analog, and discrete devices, as well as isolation, sensors, and power rail protection. Management expressed excitement about pursuing new sockets in this expanding area.

Humanoid Robotics and LEO Satellites

Humanoid robotics is identified as a key interest, with Diodes seeing similarities to automotive in terms of higher voltage requirements. The company anticipates significant opportunities in power-related components, MOSFETs, discrete devices, and power management for joint movements. Diodes is also engaging with customers in the low-earth orbit (LEO) satellite market and expects to share more details in the future.

Demand Recovery and Inventory Management

The company reported strong demand recovery, particularly in Europe, which contributed to Q1 revenue growth above seasonal trends. Management confirmed that the demand is 'real' and not driven by restocking behavior, as evidenced by a decrease in channel inventory (both in dollars and weeks) to the lower end of the normal 11-14 week range. Pricing trends stabilized in Q1, primarily due to product mix changes.

Manufacturing Utilization Outlook

Diodes' existing wafer fabs are operating at 'pretty good loading,' and the back-end facilities are 'almost fully loaded.' The company expects significant improvement in utilization for its Scotland and South Portland wafer fabs in 2027 and 2028, as customer qualifications for products produced from these facilities continue to progress, albeit taking time.

Other Income and Expenses

Total other income for Q1 FY26 was approximately $2.7 million, comprising $5.4 million in interest income, $2.5 million in unrealized gain on investments, and $0.1 million in other income. These gains were partially offset by $3.4 million in foreign currency losses, $1.2 million of impairment loss of equity investment, and $0.7 million in interest expense.
