Koh Young Technology고영

Koh Young's trailing profits are well below its 2021 level, while the share price has risen sharply over the past year.

Koh Young makes 3D inspection equipment for electronics and semiconductor makers, and it sells a brain surgery robot to hospitals. Over the twelve months to H1 2026, revenue was about ₩291B and net income about ₩48B, with a 12.4% operating margin. The shares closed at ₩29,850 on 2026-10-22, up 73.7% over one year, and sit well below their 52-week high of ₩45,000.

What stands out

• Trailing revenue of ₩291B is well above 2025's ₩233B, but operating income of ₩36B is still below the ₩41B to ₩44B reported in 2021 and 2022.
• Net income of ₩48B is well above operating income, so non-operating or other items contributed to the bottom line; the data does not explain the source.
• The model's base-case DCF value is ₩6,754 per share, far below the current ₩29,850 price; the bear and bull values are ₩5,141 and ₩9,471. The data does not explain the gap, and this is not a recommendation.
• Foreign ownership rose from 25% to 33% over about 60 days, while retail investors were net sellers of about ₩90B over the past 20 days.
• Balance sheet looks light: liabilities are 26.2% of equity and borrowings are only ₩130M against ₩32B of cash, with free cash flow of ₩30B on a trailing basis.

What to watch

• Upcoming results and whether the operating margin recovers toward the 2021-2022 range of about 16%.
• A treasury share sale decision (filed 2026-09-29, amended 2026-09-30) and the ongoing run of 5%+ holding reports, which may signal ownership changes.
• The news feed is empty in the data, so there are no recent headlines to check the filings against.
