Choil Aluminum조일알미늄

Choil Aluminum's trailing profits have thinned sharply, and the share price is down 27.8% over a year, with the stock trading well below its 52-week high.

Choil Aluminum is a Korean aluminum rolling company that makes sheet and foil for foil stock, battery cathode foil, construction, automotive and packaging uses. On trailing figures to H1 2026 it reported revenue of about ₩537B, a 4.7% operating margin and a 1.5% net margin, with free cash flow of about -₩16B and borrowings of about ₩207B. The shares closed at ₩5,010 on 2026-10-23, a market value of about ₩127B.

What stands out

• Trailing operating income is about ₩25B, up from ₩13.8B in 2025, but net income of about ₩8.1B is well below the ₩17.8B and ₩15.7B earned in 2022 and 2021.
• Debt is high relative to equity, with liabilities at 107.2% of equity and borrowings of about ₩207B against roughly ₩27B of cash.
• Trailing free cash flow is negative at about -₩16B, so the business is currently spending more cash than it generates after investment.
• The data shows the price down 27.8% over one year but up 9.6% over three months, and the close sits far below the 52-week high of about ₩11,175.
• Valuation metrics are P/E 15.7 and P/B 0.6, with no dividend yield. The data includes a DCF fair value of ₩2,306 as base case, far below the current price, but the model's bear value is zero and its bull value is ₩15,577, so the range is very wide.

What to watch

• The next full-year and quarterly results, to see whether the margin improvement holds and whether free cash flow turns positive.
• The corporate value-up plan and the buyback trust contract signed in July 2026, including how and when any buyback is carried out.
• Net foreign ownership fell to 0% from 3% sixty days earlier, and recent 20-day flows were led by retail selling, so shareholder base changes and largest-shareholder holding changes filed in July may be worth tracking.
