Revenue and profit have grown strongly since 2022, although free cash flow was negative over the trailing period. The shares closed at ₩9,950 on 2026-10-27, down 24.5% over one month but still up 72.4% over one year.

What stands out

• Trailing operating margin is 26.6% and net margin 25.2%, up from 13.5% operating margin in 2023 and 23.3% in 2025.
• Revenue rose 69.9% in 2024 and 32% in 2025, with 2025 revenue at about ₩43.5B.
• Free cash flow was about -₩1.5B on a trailing basis, and borrowings of ₩13.6B exceed cash of ₩12.2B.
• Foreign ownership fell from 3.3% to 2.6% over about 60 days, and foreign investors were net sellers over the last 20 days.
• Recent filings are dominated by major sales or supply contracts, plus amendments to those filings and the half-year report.

What to watch

• The share price is far below its 52-week high of ₩29,950; the data does not explain the recent decline.
• Whether free cash flow turns positive as revenue grows, given the negative trailing figure and rising debt relative to cash.
• Future filings on contract values and the half-year report amendments; the data contains no news headlines to explain them.
