Export restrictions and slowing China demand directly undercut GigaDevice's core domestic-and-export market; the company risks margin compression as customers scramble for alternative suppliers and order velocity slows.

## What would break the thesis

A clarification that restrictions exclude civilian consumer chips, or a swift pivot to domestic design-ins, would relieve the overhang and allow the stock to recover on secular AI demand.
