Topic: Tariff impact and automotive revenue trajectory
Key points:
No big spike or change in demand from tariffs; tariffs have been in place for some time.
Diodes uses flexible manufacturing sites to minimize tariff impact on U.S. revenue; majority of North America revenue imports into Mexico or Canada.
North America business is still a very small percentage of total revenue; overall tariff impact is relatively small.
Automotive revenue was 19% of Q3 2025 revenue; company expects automotive percentage to continue improving in 2026 due to market share gain and content expansion.
Mgmt stance: Neutral on tariffs (impact small, manageable via flexibility); bullish on automotive (expects share gain and content expansion to drive growth in 2026).
Q2 — Tristan Gerra
Topic: Gross margin catalysts from in-sourcing and SP fab qualification
Key points:
Moving wafer production from external subcontractors (e.g., in Korea or Japan) to internal fabs saves the premium paid to subcontractors; internal loading is very cost-effective.
South Portland (SP) fab qualification progress is good; new or requalified products have been qualified at key customers.
Purchase orders from SP fab have been coming in over the previous couple of quarters.
For 2026, loading at SP fab is expected to improve, helping offset OEM customer under-load issues and improving gross margin.
Mgmt stance: Bullish on gross margin improvement (in-sourcing saves subcontractor premium; SP fab loading and customer qualifications progressing well, with PO momentum).
