A Taiwan-listed electronics distributor is near collapse after both its share sale and private placement failed, and the fallout now stretches across Taiwan's hot tech market.

• Giga Rainbow's stock hit the daily limit-down five sessions running, and from October 2 it moves to full-cash settlement trading — a step that often precedes delisting.
• The company had agreed to buy medical-device maker Microlife through a subsidiary, but could not raise the money; its $30 million deposit is now forfeited, which may push its book value below zero.
• Elsewhere in Taiwan tech, passive component and ABF substrate makers surged on AI demand, with shortages reportedly lasting into 2028 and two substrate stocks hitting record highs.
• Micron beat expectations on sales and profit, but JPMorgan warned its stock crashed sharply in the month after its last strong report.
• Taipower has lost money all year and says the Middle East war has driven its gas bill far above pre-war levels, while gold stays well supported by central bank buying despite a stronger dollar.

Outlook: Giga Rainbow's shareholders face likely delisting, while Taiwan's AI supply chain keeps running hot into the fourth quarter.
