Sungwoo Techron성우테크론

Sungwoo Techron has returned to profit on a trailing basis, but its share price is well below its 52-week high and the stock trades at a low multiple.

Sungwoo Techron makes semiconductor and PCB inspection equipment and provides outsourced processing for chip lead frames and PCBs, with customers including Samsung Electro-Mechanics and LG Innotek. For the twelve months to H1 2026 it reported revenue of ₩45.8B... wait, that figure is ₩45.8B only if read literally, so the reported trailing revenue is ₩45.8B and net income is ₩7.1B, a clear improvement on 2025. The shares closed at ₩3,290 on 19 October 2026, up 22.3% over one month but down 1.2% over one year.

What stands out

• Trailing net income of ₩7.1B is well above 2025's ₩4.7B, but trailing operating income of ₩5.1B is only a modest step up from 2025's ₩2.0B, so part of the profit lift may come from non-operating items.
• Revenue has been broadly flat over the years shown, from ₩43.9B in 2021 to ₩40.9B in 2025, with a sharp drop in 2023 followed by a rebound in 2024.
• The data shows a P/E of about 4.9 and P/B of 0.4, below the peer group shown, which has P/Es mostly in the 15x to 88x range; the data does not explain why the discount exists.
• Liabilities to equity is 29.6% and cash of ₩5.5B exceeds the ₩8.5B of borrowings only by a smaller margin; trailing free cash flow is ₩4.4B.
• Recent filings include several amendments to major sales or supply contracts and a September extraordinary shareholders' meeting, but no news headlines were included in the data.

What to watch

• The next quarterly or half-year results and whether operating margin holds near the trailing 11.1%, compared with 4.8% in 2025.
• Further amendments or new major supply contracts, since the filings list shows several in 2026.
• Foreign ownership fell from 3.2% to 2.3% over the past 60 days, and the data does not state the reason; the DCF fair value figures given (₩2,816 bear, ₩5,072 base, ₩8,912 bull) are model outputs, not forecasts.
