Daewoo E&C: Losses Deepen Even as Shares Rebound Sharply Over One Year

Thesis

The data shows a sharp split between operations and the share price. Revenue has fallen from ₩11.6T in 2023 to ₩8.1T in 2025, and the company moved from a ₩403.1B operating profit in 2024 to losses in 2025 and the trailing twelve months. Despite this, the close of ₩16,090 is well above the 52-week low of ₩3,320, though below the high of ₩40,350. That suggests the market is pricing something other than current earnings, but the data does not say what. Recent filings show new supply contracts, a change of representative director, an extraordinary shareholders' meeting, a share cancellation decision and a debt guarantee for others. News mentions a ₩413B contract and possible M&A. Investor flows, foreign ownership and short balance data are not available, so we cannot see who is driving the moves.
