Taiwan Semiconductor Manufacturing (TSM) — 2025Q3 FY2025 Earnings Call Analysis

60% Gross Margin With A Capacity Ceiling

Management used the word 'insane' to describe demand, but admitted they won't know their own 2026 capacity numbers until next year.

Thesis: This is the definition of leverage. TSMC owns the bottleneck (CoWoS + N3/N2) and is flexing pricing power (GM 59.5% -> 60% guidance). The 'capacity ceiling' bear argument is noise; when you are sold out and customers are desperate ('insane demand'), you raise prices. Hyperscaler concentration (57% HPC) is the risk, but currently, those customers have nowhere else to go. The profit pool belongs to the fab.

Verdict: LONG — Conviction: HIGH

Catalyst: 2026 CoWoS capacity number update, promised for 'next year'.

Key Risk: Hyperscaler CapEx pause. If the 'insane' demand is just inventory build, the air pocket will be massive.

The Tell: When asked for 2026 CoWoS capacity numbers, C.C. Wei deflected: 'The real number, we probably update you next year.' For a company that plans CapEx years in advance, not sharing the 2026 capacity target suggests they don't know if they can physically meet the 'insane' demand.

Detected Patterns

Friction Level: HIGH_FRICTION — Bull sees a Backlog Fortress with pricing power. Bear sees a Revenue Ceiling because they physically cannot build fabs fast enough to capture the demand.
