### 모멘티브 (쿼츠·세라믹 사업부 인수) (high)
- metric: Amount ₩466.3B · FY2025 US Quartz Base Materials(모멘티브)
- note: In Jan 2020 acquired the quartz/ceramic business of US-based Momentive Performance Materials via MOMQ Holding (50% stake) — upstream vertical integration internalizing fused-quartz base materials. It secured sourcing in a raw-material market oligopolized by US/German/Japanese players, and in FY2025 US Quartz Base Materials revenue of KRW 466.3bn (49.4% of the group) became the largest segment.

### 쿼츠 원재료·설비 (비공개) (mid)
- metric: Amount ₩198.6B · FY2025 원재료 매입
- note: Purchases of fused-quartz raw materials and quartz ware — FY2025 total purchases KRW 198.6bn. Because the raw-material market is oligopolized by US/German/Japanese players, sourcing stability drives profitability; Wonik QnC internalized much of the upstream base materials via its 2020 Momentive acquisition, reducing this dependence.
