Unimicron (ISIN TW0003037008) was last at TWD 1,090.00 on the Taiwan Stock Exchange on October 16, 2026, at 1:30 p.m. CST. The latest company-linked development is a partial construction halt at its Yangmei site after a fatal workplace accident, as Finanztrends reported on October 15, 2026.

Partial halt follows one death

The accident occurred during machine maintenance at Yangmei on October 14, 2026, and the worker later died. Taoyuan labor inspectors ordered a partial construction halt on October 15, 2026, while the investigation continues. The reported order concerns part of the site rather than the entire facility.

Unimicron said the measure currently has no material effect on production or operations, according to Finanztrends. Possible penalties remain part of the official review, so the operational assessment and the regulatory outcome are separate issues.

What does the expansion mean?

Unimicron agreed on September 30, 2026, to pay TWD 10.09 billion for land and buildings at Hukou from Bridgestone Taiwan. The site includes 19 plots and 14 factory buildings, and the transaction supports longer-term high-end substrate capacity, according to Zero One Investment Research.

The chronology therefore combines an immediate safety issue with a separate capacity investment. The Hukou purchase is a TWD 10.09 billion commitment, while the Yangmei order covers one part of an existing site. The two developments should not be treated as one project.

Results arrive October 27

Unimicron's next scheduled reporting date is October 27, 2026, when third-quarter results are due, according to Boerse Global. That release will provide the next quantified test of operations after the Yangmei incident and the Hukou investment.

Stock context and company scale

Unimicron had a market capitalization of TWD 1.8 trillion as of October 16, 2026. Its 52-week range was TWD 153.80 to TWD 1,420.00 on the same date, while the Taiwan Stock Exchange listing identifies the company as an information technology business focused on circuit boards and substrates.
