TSMC is doubling CoWoS capacity from $3B to $6B, and Camtek is the only toll collector inspecting the yield.
Thesis: This is an arbitrage on CoWoS yield intensity. The market prices CAMT as a cyclical equipment supplier (15x-20x forward), but the unit economics are structural. As chiplet complexity increases, inspection steps per package rise non-linearly. TSMC doubling capacity forces a linear increase in CAMT's backlog, but the 'lag' in revenue recognition (tools ship > install > revenue) creates a mispricing window. You aren't buying a toolmaker; you're buying a royalty on HBM stack height.
Verdict: LONG — Conviction: HIGH
Catalyst: TSMC's 2H 2025 CoWoS capacity coming online. As those lines activate, CAMT's 'deferred' margin expansion from the Hawk/Eagle ramp hits the P&L in 2026.
Key Risk: China revenue (30%) is a single regulatory pen-stroke away from zero. Management calls it 'stable', but stability in a trade war is a melting ice cube.
The Tell: When pressed on 2H visibility, Ramy Langer said 'It is much too early... lead times are three to six months.' If lead times are six months, they have Q3 visibility right now. Avoiding the question suggests Q3 orders are soft or cancellable.
Friction Level: MODERATE_FRICTION — Street treats CAMT as generic cyclical WFE (5% growth). Data shows they are tethered to Advanced Packaging capacity (50% CAGR).
