Commenting on the results, Gary Yu, President and CEO of Diodes, stated, “Our third quarter revenue reached record levels coupled with an over 500-basis point year-over-year increase in gross margin to 36.1%, driving significant expansion in non-GAAP earnings. Global POS was also a record in the quarter, increasing more than 30% year-over-year. Our sequential revenue growth of more than 19% was primarily driven by record automotive revenue from continued market share gains, stronger demand across broad industrial applications, and sustained momentum in AI ecosystem applications that contributed to record revenue in the

computing market. Underpinning this growth is the benefit of the targeted investments we made in capacity expansion over the past year coming online. The resulting increase in loading at our manufacturing facilities also benefited gross margin along with product mix and pricing improvements.

“Based on our current projections for continued growth in the fourth quarter, we expect full year revenue to increase approximately 30% over 2025 at the mid-point. In addition to being well above our historical CAGR of 10%, we continue to see strong demand momentum resulting from our new product initiatives, market share gains as well as increasing content at customers. This anticipated sequential growth is once again coupled with further non-GAAP gross margin expansion of 80 basis points sequentially to 37.0% at the mid-point and increasing earnings leverage as well as strong cash flow generation.”

GAAP gross profit for the third quarter 2026 was $192.5 million, or 36.1% of revenue, compared to $120.5 million, or 30.7% of revenue in the third quarter 2025 and $147.6 million, or 33.1% of revenue, in the prior quarter. Non-GAAP gross profit was $192.9 million and non-GAAP gross profit margin was 36.2%, which excluded $0.4 million of inventory accounting associated with the acquisition of ElevATE Semiconductor.

Welcome everyone and thank you for joining us on today's conference call. As announced in our press release earlier today, we extend our momentum in the second quarter with revenue again increasing more than 20% year-over-year, driven by growth across all regions. Revenue also increased 10% sequentially, coupled with our record global POS. As the sixth consecutive quarter of double-digit year-over-year growth, this quarter serves as a further confirmation of strengthening demand in overall market, combined with Diodes expanding content across our analog and our power solutions in our key focus areas of automotive, industrial, and AI server related applications.

Automotive revenue reached a record level, up 21% of our product revenue. We continue to drive increased content with an expanding pipeline of new products that's resulting in consistent market share gains across our region's auto manufacturers and suppliers.
