Castec Korea캐스텍코리아

Castec Korea is still loss-making on a trailing basis, with a share price down 26% over the past year and a balance sheet carrying substantial borrowings.

Castec Korea makes automotive turbocharger components and other auto and appliance parts. Its trailing twelve months to H1 2026 show revenue of ₩155.7B, an operating loss of ₩5.3B and a net loss of ₩5.2B, with liabilities at 175.8% of equity and borrowings of ₩86.0B against cash of ₩9.2B. The shares closed at ₩1,232, a market value of about ₩29.9B.

What stands out

• Revenue has been roughly flat to slightly down over 2023 to 2025, at about ₩155B to ₩173B a year, and every year in the data shows an operating loss.
• The 2025 net loss of ₩21.3B was much larger than the operating loss of ₩6.3B, so the year's bottom line was hit by items beyond core operations.
• Free cash flow over the trailing period was negative at about ₩13.5B, and the data shows no dividend yield.
• The price trades at about 0.4 times book value, but no earnings-based valuation is available because earnings are negative.
• Filings in September and October 2026 are mainly amended 5%+ holding reports, and the data shows no news headlines for the period.

What to watch

• The next full-year and quarterly results, to see whether operating losses narrow from the trailing level of about -3.4% margin.
• Debt levels and the ability to fund negative free cash flow, given borrowings well above cash.
• The July 2026 lawsuit filing, whose details are not in the data, and any further holding-report amendments that could signal ownership changes.
