Model estimate based on the assumptions shown. Not a price target and not a buy or sell signal. This is not financial advice.

Why the model and the price differ

The model is 468% away from today's price. A gap this size usually means the market expects something the past figures don't show yet, or the model leaves something out. What we can see:

  • To match today's price of ₩1,903, the model needs an operating margin of 9.3% every year (it uses 21.2%).
  • Margins ranged from 11.8% to 23.0% over the last 5 years, so this is a cyclical business. The model uses the average; the price may be set by where the cycle is now. Try the margin fade option.

Treat the model as a starting point: change the assumptions to the story you believe, and compare with the multiples check below.

Bear: revenue growth 3 points lower every year, EBIT margin 2 points lower, WACC 1 point higher. Bull: the opposite.

Business

  • 21.2%

    Operating profit as a share of revenue.

    Default: through-the-cycle average of the last 12 months and the last 5 annual reports' operating margins.

  • 27.5%

    Share of operating profit paid as corporate tax.

    Default: Korea's top corporate tax rate (25%) plus 10% local income tax.

  • 17.7%

    The non-cash cost of wearing out equipment, added back to cash flow (% of revenue).

    Default: not in the statements, so 80% of capital spending (most spending replaces equipment that wears out).

  • 22.2%

    Default: average of the last 3 annual reports (cash flow statements; equipment and intangibles).

  • 40%

    Stock and unpaid customer bills, less unpaid supplier bills, as a % of revenue. Each year's extra revenue ties up this much more cash.

    Default: working capital (current assets less cash and deposits, minus current liabilities other than borrowings) as a share of revenue, averaged over the last 3 years.

Discount rate

    How fast cash flows keep growing every year after year 5.

    Default: Korea Treasury Bond 10-year yield on 2026-10-30.

  • 0.86

    The extra return investors want for owning shares instead of bonds.

    Default: a typical premium for Korean shares.

  • 5.51%

    The interest rate the company would pay to borrow.

    Default: the 10-year yield plus a 1.5% credit spread.

TTM = trailing 12 months: the last four reported quarters added together. "TTM to H1 2026" is the 12 months up to the latest quarterly or half-year report (H1 = to the end of June). Year 1 grows from there.

Past years and projection

Grey columns are reported results from the annual reports (after-tax EBIT at the model's tax rate), so you can check the growth and margin assumptions against the past. Years 1–5 are the model.

Cross-check: what the market has paid before

For cyclical businesses, analysts check a DCF against the multiples the stock has traded at through past cycles. Price / book is the usual anchor for them: P/E looks highest at the bottom of a cycle, when earnings are smallest, and lowest at the top. The price each band would give today:

LowTypicalHigh
Price / book (book value ₩5,792 a share)Now 0.33×₩2,9010.50×₩4,6340.80×₩7,6371.32×

Low, typical and high are the 10th percentile, middle and 90th percentile of month-end multiples since 2021, each against the latest report out by then, per share at today's share count; loss years and P/E above 100 are left out. Run-rate earnings are one quarter × 4, not a forecast. Model estimate based on the assumptions shown. Not a price target and not a buy or sell signal.
