WONIK QnC

What WONIK QnC does

WONIK QnC (KOSDAQ: 074600) is a global composite material components manufacturer specializing in high-purity quartz ware and functional ceramic parts for the semiconductor, display, and adjacent industries. Founded in 1983 in Gumi, Gyeongsangbuk-do, South Korea, the company operates four business divisions: Quartz (process tubes, boats, pedestals, shower heads, chambers, and etch rings for CVD, oxidation, diffusion, and plasma etching), Ceramic (Electrostatic Chucks, AlN Heaters, Pulse Heaters, and Wafer Tables using Al2O3, Y2O3, YAG, SiC, AlN, Si3N4, ZrO2, and BN chemistries), Cleaning & Coating (precision parts cleaning plus APS, SPS, PVD, and CVD coatings), and Optics (172nm Excimer UV lamps for display, 222nm sterilization lamps, CS Heaters, and Applicators). Manufacturing processes include precision CNC machining, fire polishing, welding, annealing, hot-press sintering, and inspection, with all key processes internalized. The company claims global No. 1 market share in quartz ware.

Revenue is generated primarily through enterprise hardware sales of components and consumables, with a smaller services revenue stream from precision cleaning and coating. The go-to-market is sales-led, with direct enterprise sales teams managing key accounts and equipment OEM qualification processes. The customer base is concentrated among global semiconductor manufacturers (Samsung Electronics, SK Hynix) and semiconductor equipment OEMs (Tokyo Electron, Lam Research, Kokusai, ASM, AVIZA, Intel), plus display manufacturers Samsung Display and LG Display for excimer lamp products. Wonik QnC pursues a global-for-local manufacturing strategy, operating wholly-owned subsidiaries in Taiwan (since 1996), Germany (since 2000, Geesthacht), the USA (Albuquerque since 2005; Austin since 2023 acquisition of Deposition Technology Inc.), and China (Xi'an since 2013), alongside multiple Korean production campuses and a Pangyo R&D site.

FY2025 consolidated revenue was KRW 943,641M (up 5.8% YoY from KRW 891,539M in FY2024), with operating profit of KRW 59,610M (operating margin 6.32%, down from 10.16%) and net profit of KRW 958M. The company had 1,691 employees as of December 2025, total assets of KRW 1,545,872M, and total equity of KRW 570,584M. Ownership is led by Wonik Holdings (21.0%), with the founding Lee family and Chairman Lee Yong-han jointly controlling the company.
