HSINCHU, Taiwan, R.O.C., May 15, 2026 – TSMC (TWSE: 2330, NYSE: TSM) plans to execute the sale of up to 152.0 million common shares of Vanguard International Semiconductor Corporation (“VIS”), or approximately 8.1% of VIS’ fully-diluted paid-in-capital through a block trade to financial institutional investors.
The proposed share sale will not affect TSMC’s strategic relations with VIS, including outsourcing of interposer production and licensing of GaN technology to VIS. The proposed share sale is part of TSMC’s plan to focus its resources on core business activities. In June 2024, TSMC ceased to have representation on VIS’ board of directors.
TSMC currently holds approximately 27.1% of VIS shares on a fully diluted basis. Upon the completion of this share sale, TSMC expects to reduce its shareholding in VIS to approximately 19%. TSMC has no plan to sell more VIS shares in the foreseeable future.
