Taiwan Semiconductor Manufacturing Company plans to sell up to 152 million shares in Vanguard International Semiconductor through a block trade to institutional investors. The move will reduce its ownership in VIS while keeping business cooperation between the two chipmakers in place.
The planned sale is valued at about TWD 26.8 billion, or nearly $850 million, based on current market prices. TSMC said the transaction forms part of its plan to focus resources on its core business activities.
TSMC said on Friday that it intends to sell up to 152 million shares in Vanguard International Semiconductor, also known as VIS. The shares will be offered through a block trade to financial institutional investors.
The proposed sale would reduce TSMC’s holding in VIS to about 19% from around 27.1% on a fully diluted basis. The company said it does not plan to sell more VIS shares in the foreseeable future.
The share sale comes after TSMC ended its board representation at VIS in June 2024. However, the company remains a major shareholder after the planned transaction.
TSMC said the sale supports its effort to focus capital and resources on core operations. The company continues to expand its advanced chip manufacturing, packaging, and silicon stacking capabilities amid rising demand from AI and high-performance computing customers.
TSMC said the planned divestment would not change its strategic relationship with VIS. The companies will continue cooperation in areas such as interposer production, outsourcing, and gallium nitride technology licensing.
“The proposed share sale would not affect its strategic relationship with VIS,” TSMC said, adding that business links between the companies would remain active after the transaction.
VIS plays a role in semiconductor manufacturing services and supports selected technology areas connected to TSMC’s broader supply chain. TSMC’s statement shows that the share sale is financial in nature rather than a full separation from the company.
The company also said it has no plan to sell additional VIS shares in the near term. That statement may help reduce market doubt about whether more divestments could follow after the block trade.
The announcement comes as TSMC continues to attract strong investor attention linked to artificial intelligence demand. As of May 15, 2026, TSMC shares traded around $417 to $418 per share on the NYSE.
The stock recently reached a 52-week high near $422. Its 52-week trading range stands between $188.81 and $421.97, showing a strong rally over the past year.
TSMC shares have gained more than 100% over the past 12 months. The rise reflects investor demand for companies tied to AI chips, data centers, and advanced semiconductor production.
However, the stock recently saw a modest pullback after cautious guidance on non-AI business segments. Analysts continue to watch AI demand, global chip supply, and geopolitical risks across the semiconductor sector.
TSMC is the world’s largest contract chipmaker and a key supplier for global technology companies. The Taiwan-based company provides integrated circuit manufacturing services and advanced semiconductor process technologies.
Its services include specialized process solutions, photomask support, silicon stacking, and packaging-related technologies. These capabilities support customers across artificial intelligence, high-performance computing, communications, automotive, industrial equipment, consumer electronics, and smart devices.
The company employs 76,907 people globally. It continues to invest in advanced chip production as demand grows across AI infrastructure and data-heavy applications.
The VIS share sale gives TSMC room to narrow its focus while keeping selected cooperation with Vanguard International Semiconductor. The company said the transaction will not affect existing strategic ties, including interposer production and GaN technology licensing.
