TSMC — Semiconductor Capex Cycle

Taiwan Semiconductor Manufacturing Company (TSMC) is the world's largest dedicated chip foundry — manufacturing semiconductors for Apple, Nvidia, AMD, Qualcomm, Broadcom and virtually every major fabless chip designer globally. TSMC's leading-edge process technology (3nm, 2nm) is irreplaceable for the most advanced chips, making it the single most critical node in the global semiconductor supply chain.

AI Chips: The Structural Demand Driver

Nvidia's H100, H200 and B200 AI accelerators — manufactured exclusively at TSMC — represent the single fastest-growing revenue segment in the semiconductor industry. As hyperscalers (Microsoft, Google, Meta, Amazon) invest hundreds of billions in AI infrastructure, TSMC's CoWoS advanced packaging and N3/N2 logic process are running at capacity. AI chip demand has structurally repositioned TSMC's growth trajectory above the traditional smartphone cycle.

Process Leadership: The Irreplaceable Moat

TSMC manufactures chips at 3nm and below — technology that Samsung and Intel have repeatedly failed to match in yield and reliability. This process leadership creates extraordinary customer lock-in: Apple has designed its entire chip architecture around TSMC's roadmap, and Nvidia, AMD and Qualcomm have essentially zero alternative for their leading-edge products. This moat compounds annually as TSMC's R&D advantage maintains its technology lead.

Cyclicality Within the Structural Story

Despite the AI structural tailwind, TSMC experiences significant revenue cyclicality. Consumer electronics (smartphones, PCs) — approximately 30% of revenues — follow 2–3 year inventory and demand cycles. When smartphone production slows and customers work through chip inventory, TSMC's mature process utilisation falls, compressing near-term revenues. Identifying cycle troughs in smartphone demand creates entry opportunities.

Geographic Concentration Risk: The Taiwan Factor

TSMC's dominant Taiwanese manufacturing concentration creates geopolitical risk — a Taiwan Strait military conflict would be catastrophic for global semiconductor supply. TSMC is diversifying to Arizona (US), Kumamoto (Japan) and Dresden (Europe) but Taiwan will remain over 60% of capacity through 2030. This concentration risk creates a persistent discount to intrinsic value — and potentially a discount-narrowing catalyst if Taiwan tensions ease.

Key Risks

Taiwan Strait geopolitical risk is the dominant existential concern. Customer concentration in Apple (approximately 25% of revenues) creates single-customer risk. Leading-edge process development costs are enormous — 2nm requires $20B+ fabs. US export controls restricting TSMC from selling advanced chips to China create revenue headwinds.
