Apple is reportedly about to show its first folding iPhone, and that is good news for the Taiwanese parts makers that build the hinges, circuit boards and cooling systems.

• The new phone, possibly called iPhone Fold or iPhone Ultra, is expected to open like a book, with a large inner screen and a smaller outer one.
• Taiwanese suppliers in circuit boards, heat management, casings and components are seen as the main winners, and their stocks are heating up on the story.
• Rising memory chip costs are the wild card, and buyers are watching to see how high Apple sets the price.
• The launch event, themed "Surprise and Shine," is the first in over a decade not led by Tim Cook — new CEO John Ternus takes over, with Apple past $5 trillion in value but facing EU antitrust pressure, chip shortages and an AI catch-up race.
• Rivals are already moving: Huawei just unveiled a three-way folding phone with a new in-house chip, and Xiaomi launched its first wide-folding model the same day.

Outlook: If Apple does enter the folding market, expect a fresh growth wave for high-end phones and stronger orders for its Taiwanese suppliers in the second half of the year.
