TSMC Explores Texas Site as Packaging Expansion Accelerates at Home

TSMC is considering Texas as an additional US manufacturing base alongside its $265 billion Arizona plans, as the board approves fresh capital allocations.

Taiwan Semiconductor Manufacturing Co. is weighing whether to plant a second flag on American soil, with Reuters reporting that the world's largest contract chipmaker is considering Texas as an additional US manufacturing base. The deliberations remain at an early stage, and no finalized blueprint has emerged, according to the report. The Texas option would sit alongside the company's existing commitments in Arizona, which carry a total price tag of $265 billion.

Taiwanese outlets had already floated the possibility a day earlier, pointing to a potential build-out of as many as six cutting-edge fabs in the Lone Star State. TSMC has stayed silent on the speculation. Taiwan's science minister underscored that decisions of this magnitude rest solely with the company's board of directors, which must approve and announce them.

Board Signs Off on Fresh Capital, Insiders Add Shares

Regardless of where the next US site lands, TSMC is pressing ahead with heavy spending on its manufacturing footprint. A mandatory filing with the US Securities and Exchange Commission dated September 24 shows the board of directors has cleared substantial capital allocations. The same disclosure revealed insider buying: vice presidents B.Z. Tien and Lipen Yuan lifted their holdings by 1,000 and 2,350 shares, respectively.

On the technology front, progress continues on memory integration. South Korea's SK Hynix has validated its HBM5 memory on TSMC's CoWoS packaging platform. Ground was also broken on September 21 for the first phase of the Baipu Industrial Park in Kaohsiung, a site intended to host more than 20 companies—TSMC and Foxconn among them—as a development and validation base for advanced packaging materials and equipment.

Five More Packaging Plants Eyed in Chiayi

The Kaohsiung cluster, launched with a joint groundbreaking alongside ASE Technology on September 22, is only part of the story. Reports surfaced Monday that TSMC plans to add five dedicated advanced packaging facilities as part of an expansion of the industrial park in Chiayi. Those plans have yet to be officially confirmed.

What is driving the push is unrelenting demand for computing power tied to artificial intelligence and high-performance computing. Advanced packaging has become critical to producing capable AI processors because it binds multiple memory and logic dies together in tight proximity. Bottlenecks at this stage of production have repeatedly been cited in recent quarters as the limiting factor in shipping cutting-edge accelerator chips to leading tech firms.

International Footprint Widens Beyond Arizona

Domestic expansion runs parallel to a broader global strategy. More than a month ago, Taiwanese authorities approved additional US investments, lifting the total greenlit for American projects since the end of 2020 to $44 billion. The long-term Arizona blueprint alone accounts for $265 billion.

Stock Holds Firm as October Catalysts Approach

The equity has shown relative strength against a choppy backdrop. While rising US Treasury yields and geopolitical tensions weighed on Asian indices, the stock closed yesterday's European session up 1.1% at EUR 403.00, leaving it 4.2% below its 52-week high. In today's trading, the shares are changing hands at EUR 401.00, down 0.5%, putting the gap to that peak at 4.6%.

Attention now shifts to operating data. TSMC is scheduled to release September revenue figures on October 8, a reliable gauge of how the quarter just ended performed. Full third-quarter 2026 results and the accompanying conference call follow on October 15, where management is expected to detail packaging capacity utilization and the status of its construction projects.
