Semyung Electric's trailing profits are high and its share price has fallen about 45% over the past year.

Semyung Electric makes power and rail line hardware and textile loom beams, mainly selling in South Korea. On trailing twelve months to H1 2026 it reported revenue of ₩38.4B, operating income of ₩15.2B and net income of ₩12.0B, with low debt. The share price closed at ₩6,140 on 2026-10-23, well below its 52-week high of ₩17,970.

What stands out

• Trailing operating margin is 39.6%, down from 45.8% in 2025 but far above the 2021-2024 range of 7-21%.
• 2025 revenue rose about 124% to ₩32.3B, but 2024 net income exceeded 2025's operating growth pattern only in part, so profit quality over time is hard to judge from this data alone.
• Liabilities are 16% of equity and borrowings are ₩0.4B against cash of ₩3.8B, so the balance sheet looks light.
• The fair value model gives a base of ₩9,082, below the current price of ₩6,140 and above the bear case of ₩6,418 only in the base scenario; the bull case is ₩13,183.
• Recent filings are mostly amendments to major sales or supply contracts, and the data contains no news headlines to explain the price decline.

What to watch

• The full-year 2026 results and the next quarterly report, to see whether trailing margins hold.
• Further amended major sales or supply contract filings, which may indicate changes in key contracts.
• Whether foreign ownership, currently 5.3% and down from 5.6% over 60 days, continues to decline.
