Overview
Taiwan Semiconductor Manufacturing Company (TSMC) is the largest contract chip manufacturer in the world. It produces chips designed by other companies, including most of the leading-edge processors used in smartphones, AI accelerators, and high-performance computing.
What the company does
TSMC manufactures semiconductors for fabless customers (Apple, Nvidia, AMD, Qualcomm and many others) at the most advanced process nodes.
How it makes money
Charging customers to produce chips at its fabrication plants (fabs). Pricing varies by node, leading-edge nodes carry the highest prices and margins.
Moat / competitive advantage
Process-technology leadership, deep customer relationships, massive scale, and a tightly integrated supplier ecosystem.
Business model breakdown
- •Leading-edge nodes (5nm, 3nm, future 2nm) for AI and premium mobile customers — highest pricing and margins.
- •Mature nodes for automotive, industrial, and consumer electronics — steadier but lower margin.
- •Long-term capacity agreements with key customers and large multi-year capex programs to maintain process leadership.
Key financial concepts to understand
- Capex cycle
- TSMC invests very large amounts in new fabs years before revenue materializes; free cash flow swings with this cycle.
- Gross margin by node
- Leading-edge nodes typically carry higher gross margins than mature nodes once yields are stable.
- Customer concentration
- A handful of large customers represent a meaningful share of revenue, amplifying both upside and risk.
Bull case
- •Long-term growth in AI, mobile, and HPC chip demand
- •Leadership at advanced nodes commands pricing power
- •Global fab expansion diversifies geographic risk
Bear case
- •Geopolitical shocks could disrupt operations
- •Capex intensity pressures free cash flow
- •Customer in-housing of some manufacturing
Main risks
- •Geopolitical tension involving Taiwan
- •Customer concentration
- •Cyclical semiconductor demand
- •Enormous capex requirements
Valuation questions to ask
- •How cyclical are revenues across the chip cycle?
- •What is the long-run return on capex at leading nodes?
- •How is geopolitical risk priced in?
What could break the thesis
- •A major geopolitical event disrupting Taiwan-based production.
- •Loss of process leadership to a competing foundry.
- •Sustained capex-driven destruction of free cash flow without matching revenue growth.
What beginners should learn
How a capital-intensive, technology-led business earns durable returns when its scale and process lead are larger than its competition.
Key terms beginners should know
- Foundry
- A company that manufactures chips designed by others.
- Process node
- The generation of chip-making technology, measured in nanometers (e.g. 3nm, 2nm).
- Capex intensity
- Capital expenditure as a share of revenue — very high for leading-edge fabs.
Questions to research next
- •How is revenue split between leading-edge and trailing-edge nodes?
- •What share of revenue comes from AI-related chip demand?
- •How is TSMC diversifying production outside Taiwan?
