Taiwan's Unimicron attracts up to $1.4 billion amid AI demand for chip substrates

Taiwanese Unimicron Technology plans to raise up to $1.4 billion from the sale of global depository receipts (GDRs), joining a long list of companies capitalizing on investor demand for everything related to artificial intelligence.

How many shares and at what price

Unimicron is selling 50 million shares at prices ranging from $26.96 to $27.76 per share — this represents a discount of approximately 3–6% compared to the company's base share price. At the upper end of the range, the placement could bring the company up to $1.4 billion.

Why investors are interested in substrate manufacturers

Unimicron is one of Taiwan's manufacturers of chip substrates, a critical but less visible link in the supply chain for AI accelerators compared to the GPUs themselves. The growing demand for substrates is directly linked to the boom in building data centers for AI tasks: the more accelerators and server boards the market needs, the higher the burden on substrate and chip packaging suppliers.

• Placement size — up to $1.4 billion
• Number of shares in the placement — 50 million units
• Placement price — $26.96–$27.76 per share
• Discount to base share price — approximately 3–6%

What this means

The Unimicron deal shows how investment frenzy around AI is spreading down the semiconductor supply chain — from accelerator manufacturers to less visible but equally important suppliers of substrates and chip packaging. These companies are increasingly going public to finance capacity expansion to meet growing demand from the AI industry.
