Samyoung S&C삼영에스앤씨

Samyoung S&C still loses money on an operating basis, though losses have narrowed from their 2023-2024 peak and the share price has risen over the past year.

Samyoung S&C is a small Korean maker of environmental sensors, with trailing twelve-month revenue of about ₩11.2B and an operating loss of about ₩1.3B as of H1 2026. Its balance sheet looks conservative, with cash of about ₩5.8B against borrowings of about ₩0.9B and a liabilities-to-equity ratio of 18.5%. The shares closed at ₩4,050 on 2026-10-23, sitting below the 52-week high of ₩4,230 and above the low of ₩2,260.

What stands out

• Operating losses narrowed from about ₩3.5B in 2023 and ₩3.1B in 2024 to about ₩1.7B in 2025, and the trailing figure is about ₩1.3B.
• Revenue fell 11.4% in 2025 to about ₩11.0B after a 6.4% rise in 2024, so the top line has not grown steadily.
• Trailing free cash flow is negative at about ₩1.8B, even though the company holds more cash than debt.
• Price to book is about 1.2 and price to sales about 2.1; earnings-based multiples are not meaningful because the company is loss-making, and no dividend is paid.
• Foreign ownership fell from 1.1% to 0.9% over about 60 days, while the 20-day investor flow data shows foreign buying and retail selling.

What to watch

• The next periodic results and whether the operating loss keeps narrowing toward break-even.
• Recent filings are mostly insider shareholding reports plus one 5%+ holding report dated 2026-10-16; the filings list does not say what the 5% holder's change means for the company.
• No recent news headlines were available in the data, so the reasons behind the 1-month and 3-month share price gains are not explained here.
