DOHWA ENGINEERING Amends Debt Guarantee Disclosure... Debtor Change and Slight Increase in Guarantee Balance, PF Risk Remains

Reason for amendment: Due to the absorption merger of the existing debtor Dongwoo Energy Material into DY Polymer, the debtor changed and the related debt guarantee conditions were adjusted.
Key changes: The debtor changed from Dongwoo Energy Material to DY Polymer, and the total debt guarantee balance increased slightly from 411,498,790,630 KRW to 411,973,714,630 KRW (approx. 474.9 million KRW increase).
Detailed change: The guarantee balance for subsidiary DOHWA ECO Energy No. 1 increased from 4,624,260,000 KRW to 5,099,184,000 KRW, and the guarantee period was extended from December 30, 2025 to December 30, 2026 (one year extension).
Financial impact: Total guarantee balance (411,973,714,630 KRW) is approximately 160% of equity (256,405,506,072 KRW), indicating high PF risk exposure.
Investment risk: If PF projects turn sour, the company may face significant cash outflows to honor guarantees. However, this amendment is purely administrative due to the merger, with limited change in actual risk profile.
[AI Comprehensive Analysis]This disclosure is a routine amendment, but the excessive total guarantee balance relative to equity warrants caution. In a downturn in the PF market, this could lead to liquidity risks, so investors should monitor closely.
