Daewoo E&C Shares Fall as Dukovany Construction Talks Break Down

Daewoo Engineering & Construction shares fell after talks with Korea Hydro & Nuclear Power (KHNP) over construction work at the Czech Dukovany nuclear project broke down. The Daewoo E&C–Doosan Enerbility construction consortium objected to KHNP’s decision to end the negotiations, calling it unilateral and unacceptable.

A dispute over the construction contract

KHNP is the project’s main contractor, while the consortium is seeking a construction role. The consortium’s objection leaves the status of that work in dispute. Daewoo E&C’s disclosure on the Financial Supervisory Service’s DART system was filed as a clarification of an unconfirmed report; it did not establish a final contract outcome.

The company’s filed financial backdrop

Daewoo E&C’s latest regulatory filing shows revenue changed −10.11% from Q2 2025 to Q2 2026, while operating profit changed +182.56% over the same period. Its operating margin was 11.36% in Q2 2026. Those figures cover an earlier reporting period and do not measure the effect of the Dukovany negotiations.
