Yoosung Enterprise유성기업

Yoosung Enterprise remains loss-making on a trailing basis, with its share price down sharply over the past year and no news headlines in the data.

Yoosung Enterprise, a Korean maker of engine components such as piston rings and camshafts, reported trailing twelve-month revenue of ₩281B to H1 2026 but an operating loss of ₩39B and a net loss of ₩30B. Its shares closed at ₩1,594 on 2026-10-23, near the bottom of their 52-week range of ₩1,581 to ₩2,590, and down 21.9% over one year.

What stands out

• Revenue has fallen from ₩325B in 2024 to ₩305B in 2025, and trailing revenue to H1 2026 is ₩281B, while operating margin has been negative since 2024.
• The company reports cash of ₩54B and no borrowings, but trailing free cash flow is negative at about ₩7B.
• Liabilities are 47% of equity, and the book value multiple is about 0.2, well below large peers such as Hyundai Mobis at 0.6.
• The data's DCF fair value model gives a base value of ₩634, below the current price, with a bull case of ₩3,108 and a bear case of ₩0; these are model outputs, not forecasts.
• Foreign ownership rose slightly to 9.6% from 9.1% over 60 days, while 20-day foreign net flows were negative and retail flows were positive.

What to watch

• Next quarterly and full-year results, to see whether operating losses narrow from the trailing H1 2026 level.
• The 5%+ holding and largest shareholder change filings made in August to October 2026, which may signal ownership shifts.
• The data includes no news headlines and no analyst coverage, so the company's outlook beyond the filings is unclear.
