GMB Korea지엠비코리아

GMB Korea is profitable on a trailing basis but thin-margined, and its shares have fallen over the past year despite a low valuation.

GMB Korea makes automotive parts such as transmission, engine and chassis components, mainly for Hyundai Motor, Kia and other automakers. Trailing revenue to H1 2026 was about ₩824B with operating income of ₩26B and net income of ₩21B, while borrowings of ₩209B are large relative to ₩23B of cash. The share price closed at ₩3,560 on 30 October 2026, down 9.5% over one year, with a market capitalisation of about ₩68B.

What stands out

• Revenue grew in each year from 2021 to 2025, reaching ₩787B in 2025, but operating margin has stayed around 3% and net income fell in 2025 to ₩14.5B from ₩15.4B in 2024.
• Liabilities are 127.6% of equity and borrowings are about ₩209B, so debt is a significant feature of the balance sheet.
• Trailing P/E is 3.2 and P/B is 0.2, well below peers such as Hyundai Mobis (P/E 8.3) and HL Mando (P/E 10.3), and the data shows a 7% dividend yield.
• The company's internal discounted cash flow model gives a base value of ₩5,766 per share, but the bear and bull values in the same data (₩0 and ₩65,548) are very far apart, so this estimate is not a reliable guide.
• Foreign ownership fell slightly from 56.5% to 56% over 60 days, and recent filings are mostly routine share-holding reports.

What to watch

• The half-year report for June 2026 was filed on 14 August 2026; the next periodic results and any change in the dividend are not in the data.
• Further filings on largest shareholder holdings and insider shareholding, which have been frequent in 2026.
• Debt levels relative to cash and the thin operating margin; the data names no specific upcoming events or news headlines.
