Taiwan Semiconductor Manufacturing Company said on Friday that it is planning to sell up to 152 million shares in Vanguard International Semiconductor through a block trade to institutional investors.
The company said the divestment is aimed at sharpening focus on its core operations while maintaining strategic cooperation with VIS in areas including interposer production and gallium nitride technology licensing.
The proposed transaction would lower TSMC’s holding in Vanguard International Semiconductor, also known as VIS, to around 19% from approximately 27.1% on a fully diluted basis, according to the company.
TSMC added that it does not intend to sell additional VIS shares in the foreseeable future.
At current market prices, the 152 million VIS shares are valued at roughly 26.8 billion Taiwan dollars, equivalent to nearly $850 million.
TSMC says strategic ties with VIS remain intact
The chipmaker said the planned share sale would not impact its strategic relationship with VIS.
TSMC stated that the partnership between the two companies would continue, including outsourcing interposer production and licensing gallium nitride (GaN) technology to VIS.
The company added that the transaction is part of its broader strategy to focus resources on its core business activities.
“In June 2024, TSMC ceased to have representation on VIS’s board of directors,” the company said.
The announcement comes as TSMC continues to benefit from strong investor interest tied to artificial intelligence-related semiconductor demand.
As of May 15, 2026, TSMC shares were trading around $417 to $418 per share.
The stock recently reached a 52-week high of nearly $422 amid continued optimism surrounding AI infrastructure demand.
TSMC stock posts strong gains over the past year
TSMC has recorded significant gains over the past 12 months, with the stock rising more than 100% during the period.
The company’s 52-week trading range stands between $188.81 and $421.97.
Despite the strong rally, the stock recently saw a modest pullback following cautious guidance related to non-AI business segments.
Analysts have continued to view TSMC as a major beneficiary of the growing demand for AI infrastructure, although geopolitical risks remain a concern for investors monitoring the semiconductor sector.
