### 에코프로에이치엔 (high)  → /ecopro-hn.md
- metric: Amount 1,477,438,000원 · 2026 상반기 · Per Ecopro HN related-party purchases
- note: Shared-service and other income from subsidiary Ecopro HN: KRW 1.48bn in H1 2026 (per Ecopro HN related-party purchases).
- [confirms] FSS DART (KO, filing, published 2026-08-14) https://dart.fss.or.kr/dsaf001/main.do?rcpNo=20260814001912: "Ecopro HN related-party transactions (KRW thousand): purchases from parent Ecopro 1,477,438."

### 그룹 자회사 (배당·브랜드로열티·엔지니어링 용역) (high)
- note: The standalone cash flow of Ecopro as a pure holding company — dividends, brand royalties and funding support from subsidiaries, plus a new engineering/construction-services business added in 2025 to consolidate group capex and utility operations. This income is downstream of subsidiary results, so dividends and service demand recover only as the cathode cycle turns.
- [confirms] DART (Financial Supervisory Service) (KO, filing, published 2026-03-18) https://dart.fss.or.kr/dsaf001/main.do?rcpNo=20260318001612: "Main business is equity investment in and funding support for subsidiaries; in 2025 added group engineering/construction (facilities/utilities) services."

### 이차전지 셀 메이커 (그룹 양극재·전구체) (high)
- note: On a consolidated basis, the source of group revenue KRW 3,413bn (FY2025, +9.1%) is the cell makers buying high-nickel cathodes and precursors (Samsung SDI, SK On, etc.). The EV chasm trimmed battery-materials sales slightly (-KRW 54.8bn), but a European EV recovery and rising ESS demand defended volume, and metal-price stabilization swung operating profit to a KRW 213.8bn profit.
- [confirms] DART (Financial Supervisory Service) (KO, filing, published 2026-03-18) https://dart.fss.or.kr/dsaf001/main.do?rcpNo=20260318001612: "Consolidated revenue KRW 3,413bn (+9.1%), operating profit swung positive to KRW 213.8bn; battery-materials sales slightly down, ESS and European EV recovering."
- [confirms] The Korea Herald (EN, news, published 2026-02-05) https://www.koreaherald.com/article/10670754: "Ecopro swung to a 2025 profit, driven by Indonesia investment gains and a European cathode-sales recovery."
