Thesis

The data supports a picture of improving profitability: operating margin rose from 7.7% in 2024 to 10.2% in 2025 and 12.1% on a trailing basis to H1 2026. The share price has moved well ahead of that, and the stock trades at 23.4x earnings and 3.3x book value, far above the listed peers shown.

The data does not explain why the shares rose 55.9% in three months. Many recent filings relate to major shareholders and insiders, including 5%+ holding reports, trading plans, and a change in the largest shareholder's holdings. A news headline from Chosun Biz (2026-10-13) reports a provisional seizure of shares tied to Shin Dong-kook and a ₩500B mortgage loan. The data gives no further detail on this. Investor flows, foreign ownership and short balance are not available.
