Derkwoo Electronics덕우전자

Derkwoo Electronics returned to profit on a trailing basis in H1 2026, but margins are thin and debt is high.

Derkwoo Electronics, a Gumi-based maker of precision components for mobile cameras, secondary batteries and automotive parts, reported trailing revenue of about ₩199B and net income of about ₩25B for the period to H1 2026. Operating income is small at about ₩4.6B, and free cash flow is negative at about -₩12.5B. The shares closed at ₩4,000 on 23 October 2026, up 18.9% over one month but down 6.9% over one year.

What stands out

• Trailing net income of ₩25B is far above trailing operating income of ₩4.6B, so the profit is not explained by core operations in the data given; the reason is not stated.
• Operating margin is 2.3% on a trailing basis, compared with a 0.9% operating margin for full-year 2025 and losses in 2023 and 2024.
• Borrowings of ₩69.6B against cash of ₩11.6B, with liabilities at 100.8% of equity, point to a leveraged balance sheet.
• Valuation metrics look low (P/E 2.5, P/B 0.5), but peer data is sparse and the data does not explain the gap.
• Foreign ownership fell from 2.9% to 2.0% over 60 days, while retail investors were net buyers over the last 20 days.

What to watch

• The next quarterly or annual filings, to see whether operating income and cash flow follow the trailing net income.
• The filed acquisition of convertible bonds (August 2026) and any further filings on financing or debt.
• Whether the company's recent filing on a 30% or more change in revenue or profit structure (February 2026) is followed by further disclosure; no news headlines were available in the data.
