Woori Technology's share price has swung sharply, but its recent half-year results show losses after a profitable 2023 and a loss-making 2024 and 2025 at the operating line.

Woori Technology, a KOSDAQ-listed maker of industrial control systems for Korean nuclear plants with businesses in rail, defense and other areas, reported trailing twelve-month revenue of ₩82.8B and an operating loss of ₩9.7B through H1 2026. The share price closed at ₩9,460 on 2026-10-23, down 27% over one month but up 128% over one year. Its debt is large relative to equity and free cash flow is negative.

What stands out

• Trailing revenue is ₩82.8B, but operating income is -₩9.7B and net income is -₩8.8B, giving an operating margin of -11.7%.
• Borrowings are ₩173.0B against cash of ₩4.5B, and liabilities are 123.9% of equity.
• Free cash flow over the trailing period was -₩47.0B.
• Full-year 2025 revenue grew 22.3% to ₩87.1B, yet operating income was -₩5.5B, although 2025 net income was a small ₩0.8B profit.
• Recent filings are mostly contract amendments and shareholder meeting notices, with a September 2026 decision on early acquisition of its own convertible bonds. No news headlines were included in the data.

What to watch

• The next half-year or annual results, to see whether operating losses narrow or the debt load grows.
• Further amendments to major sales or supply contracts and the outcome of the upcoming shareholders' meeting.
• Foreign ownership, which fell from 7.0% to 5.7% over 60 days, and short-selling balance of 6.9%.
