Taiwan Semiconductor (NYSE:TSM) Shows High Growth and Improving Fundamentals - ChartMill

TSMC's fundamental inflection is not a cyclical bounce—it is the margin unlock that follows 3nm/5nm yield curves crossing the break-even threshold. Upstream, ASML's EUV order backlog extends beyond 2026; downstream, fabless clients like NVIDIA and AMD face a structural BOM cost reduction in H2 2025. On compliance, the Arizona fab's depreciation drag is real, but CHIPS Act subsidy amortization timing conveniently offsets the margin pressure. The genuine risk sits in export-control long-arm effects on specialty photoresists and precursors—forcing supply chains from efficiency-optimal to redundancy-optimal, adding 15-20% hidden per-line cost. Competitively, if Samsung's 2nm GAA slips to Q2 2026, TSMC's A16 node secures a 6-9 month exclusivity window. Intel 18A remains opaque on yield; its foundry business likely will not meaningfully divert volume in 2025. TSMC's moat is not a single process node—it is the composite lock-in of process, packaging, and ecosystem. Over the next 12-24 months, CoWoS advanced-packaging capacity for AI accelerators will become scarcer than logic wafers. If TSMC lifts HBM-integrated packaging share from roughly 12% to 25%, it opens a second growth vector—a structural advantage Samsung and Intel cannot replicate within two years.
