What stands out

• Revenue fell from ₩262B in 2025 to about ₩196B on a trailing basis, and operating margin is around -132%.
• The trailing net loss of about ₩1.58T is far larger than the operating loss, but the filed data here does not explain the gap.
• Liabilities are about 152% of equity and free cash flow is negative at about -₩175B.
• Shares are down 53.4% over one year but up 10.3% over three months; the stock is priced at about 1.0x book value with no dividend.
• Filings in August and September 2026 include a merger decision, a correction to that decision, a shareholders' meeting call and a trading halt, while the news feed returned no headlines.

What to watch

• The merger decision and its correction, which the filing titles name but the data does not detail.
• The next results release, since trailing losses and negative free cash flow are the main pressure points.
• Foreign ownership rose from 3.8% to 6.4% over 60 days while retail investors were net sellers over the last 20 days.
