Union Semiconductor Equipment's trailing profit has held up on revenue near ₩288B, but cash flow is negative and the share price is well below its 52-week high.

The company makes gas scrubbers and chillers for semiconductor and display plants, and its trailing twelve-month revenue is about ₩287.8B with operating income of about ₩14.5B for the period to H1 2026. Free cash flow was negative at about -₩0.4B, and the shares closed at ₩8,830 on 2026-10-23, roughly 39% below the 52-week high of ₩14,390. The data shows a modest-looking balance sheet with low leverage and no reported borrowings.

What stands out

• Revenue for the trailing period to H1 2026 is about ₩287.8B, above the ₩273.3B reported for 2025, while the 2025 operating margin was 4% and the trailing operating margin is 5%.
• Net income for the trailing period (about ₩20.5B) is well above operating income, and the data does not explain the difference.
• Net income fell from ₩38.2B in 2021 to ₩9.0B in 2025, and ROE fell from 20.8% to 3.8% over the same period.
• Valuation looks low on the data shown: P/E of 13.2, P/B of 1.1 and a DCF base value of ₩10,243 against the ₩8,830 close, with a bear-to-bull range of ₩7,093 to ₩15,337.
• Foreign ownership rose from 16.8% to 17.4% over about 60 days, while 20-day retail flows were net negative at about -₩2.3B. Several 5%+ holding reports were filed between July and October 2026.

What to watch

• The next quarterly or annual filings, to see whether operating margin and cash flow improve from the current levels.
• Further 5%+ holding reports, which may show changes in major shareholders.
• The data includes no news headlines and no analyst coverage, so the company's outlook beyond the filings is not visible here.
