Taiwan's Unimicron seeks to raise up to $1.4 billion as AI demand lifts chip substrate makers

Taiwan's Unimicron Technology plans to raise up to $1.4 billion by selling global depositary receipts (GDS), joining a long list of companies cashing in on investor demand for anything tied to artificial intelligence.

How many shares, and at what price

Unimicron is selling 50 million shares at $26.96 to $27.76 each, a discount of roughly 3–6% to the company's base share price. At the top of the range, the offering could bring in up to $1.4 billion.

Why investors are looking at substrate makers

Unimicron is one of Taiwan's makers of chip substrates, a critical but less visible link in the AI accelerator supply chain compared with the GPUs themselves. Demand for substrates is directly tied to the boom in AI data center construction: the more accelerators and server boards the market needs, the greater the load on suppliers of substrates and chip packaging.

• Offering size: up to $1.4 billion
• Number of shares offered: 50 million
• Offer price: $26.96–$27.76 per share
• Discount to the base share price: about 3–6%

What it means

The Unimicron deal shows how investment enthusiasm for AI is spreading down the semiconductor supply chain, from accelerator makers to less visible but equally important suppliers of substrates and chip packaging. These companies are increasingly turning to public capital markets to fund capacity expansion for growing demand from the AI industry.
