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 145% 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 ₩1,308, the model needs an operating margin of 3.1% every year (it uses 4.0%).
  • Or revenue growth −12.4 points a year higher than assumed in each of the 5 years.
  • Today's P/E is 6.0× against a typical 6.3× over the last 10 years.

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

Margin path

Every year uses the cycle-average margin (4.0%).

Revenue growth

  • 5.5%

    How much sales grow that year, compared with the year before.

    Default: the last 3 years' revenue growth (5.5% a year, annual reports), fading to 3% by year 5.

  • 4.9%

    How much sales grow that year, compared with the year before.

    Default: the last 3 years' revenue growth (5.5% a year, annual reports), fading to 3% by year 5.

  • 4.3%

    How much sales grow that year, compared with the year before.

    Default: the last 3 years' revenue growth (5.5% a year, annual reports), fading to 3% by year 5.

  • 3.6%

    How much sales grow that year, compared with the year before.

    Default: the last 3 years' revenue growth (5.5% a year, annual reports), fading to 3% by year 5.

  • 3%

    How much sales grow that year, compared with the year before.

    Default: the last 3 years' revenue growth (5.5% a year, annual reports), fading to 3% by year 5.

Business

  • 4%

    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.

  • 4.2%

    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).

  • 5.2%

    Money spent on factories, equipment, software and other long-term assets (% of revenue).

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

  • 19.5%

    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

  • 2%

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

    Default: about Korea's long-run inflation plus real growth.

  • 4.08%

    Yield on Korea's 10-year government bond: the return with almost no risk.

    Default: Korea Treasury Bond 10-year yield on 2026-10-29.

  • 0.6

    How much the share moves when the market moves: 1 means just like the market.

    Default: 105 weeks of weekly returns against KOSPI (official index); raw beta 0.24, adjusted toward 1 and kept between 0.6 and 2.0.

  • 5.5%

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

    Default: a typical premium for Korean shares.

  • 5.58%

    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 ₩4,741 a share)Now 0.28×₩1,7580.37×₩2,6100.55×₩4,3240.91×
Price / earnings (last 12 months: ₩216 a share)Now 6.04×₩9564.42×₩1,3656.31×₩2,98313.8×
P/E on run-rate earnings (Q2 2026 × 4: ₩358 a share)Now 3.66×₩1,5804.42×₩2,2556.31×₩4,92813.8×

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.
