Track an expansion as a chain of dependencies, not as a single investment or capacity figure. Follow construction, equipment delivery, qualification and high-volume production alongside critical materials, supplier readiness, demand, site geography and trade rules. The key distinction is whether a company has announced a plan, is building capacity, or has reported qualified output.
Start by separating announced capacity from usable output
A fab announcement describes an intention, not production that customers can use. New buildings and investment figures do not establish when tools will be installed, processes qualified, yields achieved or output delivered at scale. Track the milestones separately, and label each one as a company-reported result, an expectation or a forward-looking plan.

For each site, record the date and source of the latest update, the milestone reached, the next stated milestone and any stated uncertainty. Useful stages include construction, equipment installation, process qualification and high-volume manufacturing. A target date is a checkpoint to revisit, not a guarantee.

In its 2025 annual report, TSMC said its first Arizona fab entered high-volume production in the fourth quarter of 2024; its second fab was expected to enter high-volume manufacturing in the second half of 2027; and construction of its third fab began in 2025. The first is a reported milestone, while the latter two describe an expectation and a construction update—not equivalent amounts of available production.

Monitor the dependencies that can hold up a ramp
A fab needs more than a completed building. TSMC says expansion relies on equipment and related services from a limited number of suppliers, with long delivery cycles; delays in tools or parts can prevent capacity plans from being executed on time. It also identifies silicon wafers, gases, chemicals and photoresist as required inputs, and describes monitoring supplier capacity and quality, inventory, continuity plans and qualified alternatives.
| Risk area | What to monitor | Why it matters |
|---|---|---|
| Construction and production ramp | Site updates, stated start dates, tool installation, qualification, disclosed yields and high-volume production milestones | A planned site or investment does not establish qualified, usable output. Company disclosures may distinguish completed milestones from targets. |
| Equipment and services | Delivery lead times, service availability, bottleneck tools, supplier concentration and export-license conditions | Limited suppliers and long delivery cycles can constrain the timing of a ramp. |
| Materials and upstream suppliers | Availability and price of wafers, gases, chemicals, photoresist and other critical inputs; supplier capacity and quality; continuity plans and qualified alternatives | Inputs must be available in the right specifications and quantities when production needs them. |
| Inventory and demand | Inventory indicators, forecast revisions, customer commitments and customer concentration | Capacity plans respond to demand forecasts, and concentrated demand can make output plans more sensitive to a small number of customers. |
| Geography and infrastructure | Country and site distribution, disclosed local infrastructure constraints, government support and policy changes | A new location may alter exposure without proving that its tools, inputs or processes are independent of other regions. |
| Trade and regulation | Export-control rules, licenses, tariffs, restrictions on customers or destinations, and countermeasures | Rules can delay or prohibit shipments and can affect equipment availability as well as product sales. |
These indicators are not all public at the same level of detail. TSMC’s public disclosures describe its risk-management practices, but they do not reveal every supplier tier, current inventory position, tool-specific bottleneck or confidential customer commitment. Treat unavailable details as unknown rather than inferring that a risk is absent.
Assess whether new sites actually diversify exposure
Count more than the number of countries or fabs. Compare geography and policy exposure with the process node, advanced-packaging capability, supplier dependencies and time to qualified high-volume production. Wafer capacity at different nodes, packaging stages or sites is not automatically interchangeable; a site count alone does not show that a particular product can be made elsewhere.
TSMC reports facilities across Taiwan, China, the United States and Japan, and says it expands its footprint in response to customer needs and government support. The U.S.-China Economic and Security Review Commission’s 2025 report cites underlying estimates that Taiwan and South Korea held 69% and 31%, respectively, of sub-10-nanometer fabrication capacity as of 2022. Those figures describe that technology scope and year; they are not a measure of all semiconductor production today.
Use company figures as context, not as a substitute for milestones
TSMC reported more than 17 million 12-inch-equivalent wafers of annual manufacturing capacity in 2025 in its 2025 Form 20-F. That company-wide figure gives scale, but does not identify how much capacity at a specific site, node or packaging stage is qualified for a particular customer’s needs.
Investment announcements need the same care. On March 4, 2025, TSMC announced an additional $100 billion in intended U.S. investment, bringing its stated total intended U.S. investment to $165 billion. Samsung Electronics disclosed on December 23, 2024, that at least $37 billion was planned for its Texas semiconductor plant, with operations tentatively set to commence in 2026; Samsung said timing and investment amount could change. These are dated company plans, not evidence in themselves that the announced spending has become production capacity.
Include customer concentration in the risk picture
Expansion is useful only in relation to demand for the output it can make. TSMC’s 2025 annual report says its ten largest customers accounted for approximately 70% of its net revenue in 2023, 76% in 2024 and 78% in 2025. These are TSMC-specific revenue-concentration figures, not industry-wide measurements. When tracking an expansion, pair company demand forecasts with disclosed customer commitments or concentration information where available; do not assume that a capacity announcement guarantees demand.

- Set the scope. Identify the manufacturer, site, process or packaging capability, relevant product and geography. Avoid comparing nominal wafer figures across different nodes or stages as if they were interchangeable.
- Log milestones with evidence and dates. For each site, note whether a statement is a reported event, a current expectation or a longer-term plan. Capture subsequent company filings and updates so that a changed target is visible.
- Track upstream readiness. Record disclosed equipment constraints, delivery timing, material availability, supplier qualification, continuity measures and alternate sources. Note when a key detail is not public.
- Watch demand and policy alongside construction. Follow forecast or customer updates, customer concentration where disclosed, export licenses, trade restrictions and government-support changes that could affect the site or its suppliers.
- Reassess the bottleneck, not just the headline. Ask which dependency now governs usable output: construction, equipment, qualification, inputs, demand or policy. Update the risk assessment only when the evidence changes.
TSMC’s risk-management page describes mapping risks, identifying alternative sources, maintaining strategic inventories, proactive monitoring and scenario planning, alongside global-footprint expansion and government engagement. Those practices point to a useful discipline for readers: treat expansion risk as an evolving network of dependencies rather than a one-time announcement.
