Hyundai E&C Business Trends and Guarantee Risk Monitoring — October 10, 2026

Hyundai E&C has kicked off its European nuclear market expansion by signing a Phase 1 Front-End Engineering Design (FEED 1) contract for a new large-scale nuclear power plant in the Netherlands with Westinghouse. On the other hand, its stock price showed volatility, falling about 3.79% from the previous day, and disputes over construction cost settlements with subcontractors persist at major sites like the Shaheen Project.

Major Business Changes and Risk Signals

• Netherlands Nuclear FEED Contract Signed: Hyundai E&C announced on the 8th that it has signed a Phase 1 Front-End Engineering Design (FEED 1) contract for the construction of a new large-scale nuclear power plant in the Netherlands, partnering with the U.S.-based Westinghouse. This contract is for building two AP1000-based nuclear reactors and is expected to serve as a stepping stone for expanding nuclear orders in Europe.
• Stock Market Reaction: As of the morning of the 8th, Hyundai E&C's stock opened at 110,700 won, reached a high of 110,800 won, and hit a low of 106,100 won, marking a 3.79% drop. This is interpreted as a reflection of short-term market sentiment contraction despite the positive news of the nuclear order.
• Hyundai Engineering's New Business Participation: Hyundai Engineering, a subsidiary of Hyundai E&C, is participating in a national research project hosted by the Korea Institute of Energy Technology Evaluation and Planning for the "Demonstration of Hybrid Water Electrolysis Plants Matched to Wind Power Fluctuations." It plans to strengthen its competitiveness in the hydrogen energy sector through technology development combining alkaline and PEM methods.
• Financial and PF Risks: No specific financial risk disclosures, such as a sudden surge in unsold properties or obligations to fulfill PF guarantees by Hyundai E&C, have been confirmed within the last 24 hours. However, the importance of builders' credit ratings and cash flow is being emphasized across the PF securitization market as a whole, warranting continued monitoring.

Guarantee Risks and Partner-Related Issues

• Shaheen Project Subcontractor Disputes: During the construction of S-Oil's Shaheen Project, settlement disputes regarding "over-incurred" construction costs have arisen between Hyundai E&C and certain subcontractors. This highlights the gap in perception between the main contractor and subcontractors regarding cost fluctuations during project execution.

  

• Subcontract Unit Price Increases and Win-Win Agreements: In a meeting of the public-private consultative body consisting of the Fair Trade Commission and 19 large construction companies (including Hyundai E&C), it was revealed that subcontract supply unit prices were additionally raised by about 73.7 billion won following the signing of win-win agreements. While this is a measure to ease the cost burden on partner companies, it could act as a pressure point for rising costs.
• Continued Cost Ratio Burden: Based on past data, Hyundai E&C's cost ratio sits around 97.91%. While relatively favorable compared to its subsidiary Hyundai Engineering (105.35%), it remains high. Although some analyses suggest that rising construction costs could turn into a blessing in disguise, practical cost management is required.

Market Analysis and Practical Insights

• Expansion of Nuclear Portfolio: Unlike Samsung C&T and Doosan Construction, which focus on maintenance and public project orders, Hyundai E&C is strengthening its position in the overseas high-value nuclear market through the Dutch nuclear FEED contract. This could lead to a qualitative improvement in future order backlogs.
• Notes for Practitioners: Since construction cost settlement disputes with subcontractors are occurring at large-scale plant sites like the Shaheen Project, it is essential to thoroughly manage supporting documents for contract modifications and additional construction, and to check for potential violations of the Subcontracting Act. In addition, in accordance with the implementation of the subcontract price linkage system, it is crucial to clearly reflect raw material price fluctuations in contracts.
