Samyoung Electronics삼영전자

Samyoung Electronics shows thin margins and a shrinking top line, with a designation for an unfaithful disclosure weighing on sentiment.

Samyoung Electronics makes capacitors and capacitor materials for home appliances, automotive, 5G, medical and SSD uses, with most sales exported. Trailing twelve-month revenue is about ₩150.8B with a 4.6% operating margin and 2.8% net margin, and the shares closed at ₩11,800 on 23 October 2026, roughly 34% below the 52-week high of ₩17,990. The company was designated as an unfaithful disclosure company in June 2026, and the data does not describe any operational effect of that designation.

What stands out

• Revenue fell 8.1% in 2025 to about ₩149.7B, and operating income dropped from ₩9.2B in 2025 to a trailing figure of about ₩6.9B.
• Net income in 2024 and 2023 was higher than operating income, and 2025 net income of ₩5.1B was below 2025 operating income, so earnings quality varies year to year.
• The balance sheet looks light: liabilities are 8.6% of equity, cash is about ₩22.1B and borrowings are only about ₩0.2B, though ROE is just 0.7%.
• The stock is down 7.2% over one month and 10.6% over three months, but up 9% over one year; the trailing P/E of 55.2 sits well above the 2025 year-end P/E of 41.2 and the P/B is 0.4.
• Foreign ownership eased from 40.6% to 40% over sixty days, while retail investors were net sellers over the last 20 days, and the company's own DCF model gives a base value of ₩20,281 (bear ₩18,531, bull ₩23,514), which is a model output and not a forecast.

What to watch

• The unfaithful disclosure designation and two lawsuits listed in June 2026; the data does not say what they concern or their outcome.
• Full-year 2026 results and the next quarterly filing, since the latest data covers only half-year 2026.
• Whether the margin recovers toward the 6.2% operating margin seen in 2025, given that revenue has declined for several years.
