Comet Holding AG is a leading Swiss technology company specializing in radio frequency (RF) power delivery and X-ray technology. It is a critical subsystem supplier to the global semiconductor equipment industry, with its technology embedded in the plasma etch and deposition tools used to manufacture advanced microchips.

• Embedded Technology: Comet's PCT division is a global leader in plasma control subsystems. Its RF networks and vacuum capacitors are structurally inseparable components inside the chamber tools of major WFE manufacturers.
• Tier-1 Supplier Status: Strategic alignment with Lam Research (48% of group revenue) and Applied Materials.
• Technological Complexity: High barriers to entry in RF power delivery for advanced gate-all-around (GAA) logic and 3D NAND processes.
• Complementary Ecosystem: Functions as part of a "holy trinity" of Swiss subsystem suppliers alongside VAT Group (vacuum valves) and Inficon (sensing), often integrated into the same tool platforms.

• Synertia Platform: Successful launch of the next-generation RF subsystem targeting advanced GAA logic processes, expected to represent 25% of PCT shipments by 2027.
• Advanced Packaging: Increasing demand for the IXS CA20 system, which uses 3D X-ray and AI for automated defect recognition in chiplets and HBM.
• Penang Expansion: Scaling production in Malaysia to provide regional supply chain diversification and long-term cost tailwinds.

• Customer Concentration: Extreme dependence on Lam Research (78% of PCT revenue) makes Comet highly sensitive to Lam's market share and capital spending cycles.
• Memory Cycle Sensitivity: Highly leveraged to memory WFE spending (NAND/DRAM); recovery lags tool orders by 1-2 quarters.
• Execution Risk: Duplicate costs during the Penang facility ramp and the need for high-volume adoption of the CA20 system.
• FX Exposure: Predominantly USD-denominated revenue base creates margin pressure from a strong Swiss Franc (CHF).
