The Kumamoto facility focuses on mature process technologies—12nm, 16nm, 22nm, and 28nm—primarily serving automotive and industrial chip customers. Demand from those segments helped raise capacity usage enough to push the operation into the black.

TSMC’s plans for the site are also evolving. The company has begun construction of a second Kumamoto fab, and plans for that facility are shifting toward more advanced nodes such as 3nm in response to strong global demand linked to artificial intelligence.

Arizona: AI Demand Drives Record Quarterly Profit

TSMC’s Arizona operation produced the most dramatic financial improvement. The facility generated NT$18.81 billion in profit in Q1 2026, up from NT$11.37 billion in the previous quarter and NT$496 million a year earlier.

That single quarter exceeded the unit’s entire 2025 profit of NT$16.14 billion, underscoring how rapidly the U.S. operation’s economics are improving as production scales.

A major driver has been surging demand for chips used in artificial intelligence systems, particularly from large U.S. technology customers. The Arizona fab is producing 4nm chips, which are far more advanced than the processes used in Kumamoto and are widely used in high‑performance computing and AI workloads.

As demand for these chips continues to rise, higher utilization of the advanced-node production lines is boosting revenue and profitability.

Germany: Still in the Investment Phase

TSMC’s European project, European Semiconductor Manufacturing Co. (ESMC) in Dresden, remains in a different stage of development.

The joint venture—70% owned by TSMC—reported a NT$278 million loss in the quarter, reflecting the fact that the fab is still under construction and has not yet begun commercial production.

Such early losses are typical for semiconductor projects, where massive upfront investment occurs years before meaningful output begins.

Expansion Strategy Behind the Numbers

These results reflect a broader global manufacturing strategy as TSMC diversifies production beyond Taiwan.

In the United States, the company’s Arizona investment has expanded into a massive plan that includes:

• Multiple advanced semiconductor fabs
• Two IC assembly facilities
• A research and development center

The initiative is expected to total about US$165 billion when fully built out.

Japan is also becoming a key part of TSMC’s network. The company holds a 77% stake in the Kumamoto venture, and construction of the second fab indicates the site may gradually move beyond mature-node production toward more advanced chips.

Meanwhile, the Dresden project represents TSMC’s entry into Europe’s semiconductor ecosystem, aimed largely at supporting automotive and industrial chip supply chains.

Subsidies Drop Sharply

Despite the large government support packages associated with many semiconductor projects, TSMC reported receiving NT$505 million in subsidies from the U.S., Japan, and Germany in the quarter, a 98.56% decline from a year earlier.

That sharp drop suggests the latest improvement in overseas profitability was driven more by operational factors—demand and utilization—than by new government funding.

What the Quarter Signals

TSMC’s overseas fabs are moving into different phases of maturity:

• Arizona is benefiting from booming AI‑chip demand and advanced-node production.
• Kumamoto is stabilizing as mature-node capacity fills up.
• Germany remains an early-stage investment that will take years to generate revenue.

Taken together, the results suggest TSMC’s strategy of building a geographically diversified manufacturing network is beginning to produce financial returns—especially as global demand for AI chips accelerates.
