Senko센코

Senko's trailing earnings are solid on paper, but its share price is down 20.5% over the past year and sits well below its 52-week high.

Senko is a Korean maker of gas sensors, gas safety instruments and environmental measurement devices sold through distributors in 45 countries. On trailing twelve months to H1 2026 it reports revenue of ₩42.3B... of about ₩42.3B, operating income of ₩2.9B and net income of ₩7.3B, with net income well above operating income, which the data does not explain. At ₩1,833 the shares trade at a P/E of 9.6 and P/B of 1.1, while the data's DCF base value is ₩1,146, below the current price.

What stands out

• Revenue has been broadly flat to modestly growing: 2025 revenue was ₩36.7B, up 2.4%, after ₩35.9B in 2024 and a 16.8% fall in 2023.
• Operating margin has eased from 9.6% in 2021 to 6.8% in 2025 and the TTM figure, while net income is far above operating income in the TTM period, so non-operating or one-off items likely matter; the data does not break this down.
• Balance sheet looks conservative: liabilities are 23.4% of equity, cash is ₩12.4B against borrowings of ₩3.2B.
• Foreign ownership rose from 1.8% to 2.5% over about 60 days, while retail investors were net sellers of about ₩62M over the last 20 days.
• Filings in the last few months include a disposal of tangible assets, a management-related major matter with an amendment, and several amended supply contract reports; the news feed is empty, so the data gives no context for these.

What to watch

• Details of the amended management-related major matter and the tangible asset disposal, which the data does not describe.
• Next quarterly and annual results, to see whether the gap between operating and net income persists and whether margins hold near 7%.
• Share price remains well below the 52-week high of ₩2,625 and the DCF bear-to-bull range is wide (₩782 to ₩1,788).
