### Centennial Optical (캐나다) (high)
- note: HOYA Vision Care's June 2025 acquisition of Centennial Optical (a Canadian ophthalmic distributor) is not a one-off deal but the execution of a 'Life Care x M&A' strategy — leveraging ~JPY 187.4bn net cash to grow annuity-like revenue in non-cyclical Life Care, a portfolio design meant to offset the swings in cyclical IT earnings.

### 소재·원재료 (합성석영·저열팽창유리·Mo/Si 타깃) (mid)
- note: Hoya's vertical integration — it melts its own glass — keeps input-cost exposure low; it procures mainly synthetic quartz/special-glass materials and Mo/Si/Ru sputter targets for EUV multilayers, with quarterly raw-material cost just 12.8% of sales (JPY 31.8bn). That low materials dependence is the moat behind the IT segment's 54% margin.
- [mentions] HOYA Corporation (EN, filing, published 2026-04-30) https://ssl4.eir-parts.net/doc/7741/tdnet/2797234/00.pdf: "Raw materials and consumables used JPY 31,829m in the quarter (12.8% of sales)."

### 라이프케어 원가 (렌즈 소재·의료부품·유통) (mid)
- note: Life Care's cost base (revenue JPY 590.7bn, +7.2%) is the opposite of IT's — a regulation- and distribution-heavy business with a higher cost ratio but low cyclicality, so the steady cash it throws off acts as the ballast that funds cyclical IT capacity investment and share buybacks.
