### Sunny Smart Autotech(차량광학 자회사 분사) (high)
- note: Pursuing a Hong Kong spin-off and separate listing of vehicle-optics subsidiary Sunny Smart Autotech (application 26 Jan 2026) — carving out the group's highest-margin, fastest-growing unit for a standalone valuation, a capital move to crystallize the vehicle-business value the market has underpriced.

### 광학소재(유리·수지) 공급사(익명) (mid)
- note: Lenses are built from optical glass (spherical/aspherical) and optical resin, so stable sourcing of these materials is the precondition for scaling high-end lens output — with some core materials and high-precision equipment in limited supply, this material-and-tooling bottleneck is where the pace of premiumization is decided (suppliers undisclosed).

### 이미지센서·전자부품 공급사(익명) (mid)
- note: Camera modules are assembled around externally sourced core parts — CMOS image sensors (CIS) and voice-coil motors — so sensor supply and pricing dictate cost and lead times; the filing withholds names, but concentration (largest 16.2%, top-5 33.6%) makes reducing single-supplier dependence central to risk management.
- [confirms] Sunny Optical Technology (EN, filing, published 2026-04-24) https://www.sunnyoptical.com/webfile/temps/202604317462754261.pdf: "Largest supplier 16.2%, top-5 33.6% of purchases."
