Revenue model

1. Specialty Gas Sales: SK Specialty generates revenue primarily through the production and sale of specialty gases and chemicals to semiconductor, display, and solar cell manufacturers. The company supplies critical process gases including NF3, WF6, silane-based gases, etching gases, and high-purity gases. Revenue is derived from long-term supply contracts with major semiconductor customers.
2. Integrated Services: The company provides integrated services including new product R&D, portfolio diversification support, gas sourcing/purification/mixing, quality upgrades, and logistics/warehouse operations. These services complement product sales and create additional revenue streams through value-added service provision.
3. Precursor Materials: SK Specialty manufactures and sells precursors (Zr, Si, Ti, Hf) for next-generation semiconductor processes, with a strategic partnership with Tri Chemical Laboratories (Japan) for precursor technology collaboration.
