TSMC (TSM) has announced plans to sell up to 152 million Vanguard International Semiconductor (VIS) shares through a block trade to financial institutional investors.
Taiwan Semiconductor Manufacturing Company Limited, TSM
The sale is worth roughly 26.8 billion Taiwan dollars, or about $850 million at current prices.
The transaction will reduce TSMC’s stake in VIS from around 27.1% to approximately 19% on a fully diluted basis.
TSMC was up around 4.48% on the day the news broke, while VIS rose around 0.86%.
The company was clear this is not the start of a full exit. TSMC said it has no plans to sell additional VIS shares in the foreseeable future.
Instead, the chipmaker framed this as a targeted portfolio adjustment — a way to free up resources and sharpen its focus on its core contract manufacturing business.
Strategic Ties Stay Intact
Despite the reduced ownership, TSMC stressed that its operational relationship with VIS will not change.
That includes outsourcing interposer production to VIS and continuing to license gallium nitride (GaN) technology to the company. These are niche but important parts of the supply chain.
So while the financial stake shrinks, the two companies remain closely linked in practical terms.
It’s worth noting that TSMC already stepped back from VIS governance. In June 2024, TSMC ceased to have representation on VIS’s board of directors.
This share sale looks like a natural continuation of that gradual separation — financial ties loosening while technical collaboration holds.
Block Trade Structure
The sale will be conducted as a block trade, a method commonly used for large equity transactions. It’s designed to move a big chunk of stock to institutional buyers without rattling the open market.
By targeting institutional investors directly, TSMC avoids the kind of price pressure that a public sell-down on the open market could cause.
This approach signals careful execution on TSMC’s part — not a rushed or reactive move.
VIS, known as Vanguard International Semiconductor, is a Taiwan-listed chipmaker focused on specialty technologies. It’s not TSMC’s core rival — it operates in a different part of the market.
TSMC remains the world’s largest contract chipmaker, and its capital allocation decisions attract close attention across the semiconductor sector.
The block trade to institutional investors is expected to proceed following the announcement.
TSMC said the share sale forms part of its broader plan to concentrate resources on its primary manufacturing activities.
