What stands out

• Trailing revenue of ₩23.8B is down from ₩37.2B in 2024 and ₩23.6B in 2025 shows a steep fall from the 2024 level.
• Operating margin is about -4.1% and net margin about -4.0% on a trailing basis; 2024 was the only recent year with a net profit, and it was driven by a net income figure well above operating income.

• Price has fallen 50.7% over three months, and foreign ownership rose from 1.6% to 4.1% over about 60 days while the 20-day foreign flow was negative.
• Recent filings include a major sales or supply contract (2026-08-21), a rights offering amendment, and a notice on potential designation as an administrative issue because market capitalization fell below ₩20B.

What to watch

• The exchange notice on potential administrative issue designation, which the data links to market capitalization below ₩20B.
• Next results and the full-year 2026 filing, since the trailing figures only run to H1 2026 and the data includes no forecasts.
• Progress of the rights offering and convertible bond transactions, which bear on share count and funding; the data does not state their terms in detail.
