HS Hyosung Advanced Materials Provides KRW 22.67B Guarantee for Affiliate; Total Guarantees Reach 210% of Equity, Highlighting Contingent Liability Risk


  • HS Hyosung Advanced Materials decided to provide a debt guarantee of KRW 22.67 billion (USD 15 million, exchange rate 1USD=1,511.30 KRW) for its affiliate GST Automotive Safety Components International LLC's new loan facility. Guarantee period from June 2, 2026 to June 16, 2027.
  • With this guarantee, total outstanding guarantees of HS Hyosung Advanced Materials increased to KRW 1.7347 trillion, equivalent to 210% of its equity (KRW 826.5 billion, consolidated end-2025), highlighting excessive contingent liability risk.
  • The debtor GST Automotive's 2025 financials show total assets of KRW 130.5 billion, liabilities of KRW 109.2 billion, equity of KRW 21.2 billion, but a net loss of KRW 37.8 billion, indicating weak profitability. In the prior year, equity was negative (-KRW 25.4 billion), and while it turned positive in 2025, it remains fragile.
  • This guarantee was approved by the management committee; attendance of outside directors is not separately disclosed.
  • [AI Summary]The additional debt guarantee pushes HS Hyosung Advanced Materials' total guarantee balance to over twice its equity, raising concerns about financial soundness. If the debtor's poor performance persists, the likelihood of actual guarantee execution increases, warranting investor caution and potentially weighing on the stock price.
