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 65% 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 ₩77,200, the model needs an operating margin of 27.6% every year (it uses 11.4%).
  • Or revenue growth +38.4 points a year higher than assumed in each of the 5 years.
  • Analysts' forecasts for 2026: revenue ₩409B, operating profit ₩69B (16.9% margin) (1 broker). The model starts from the last 12 months reported.
  • Analysts' forecasts for 2027: revenue ₩482B, operating profit ₩88B (18.3% margin) (1 broker). The model starts from the last 12 months reported.
  • Margins ranged from 3.4% to 16.6% 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.
  • 33% of the last 12 months' net profit came from outside operations (stakes in other companies, interest, one-offs). The model adds those stakes at book value but doesn't project that income.
  • In the projection, spending on equipment, software and working capital takes most or all of the after-tax operating profit, so free cash flow is thin. Companies that invest heavily often look like this until spending slows.
  • Today's P/E is 21.0× against a typical 61.6× over the last 10 years.

Cycle options

Start from

Preliminary results are the company's early announcement of a quarter's sales and operating profit, before the full report. Including them swaps that quarter in for the same quarter a year earlier.

Margin path

Every year uses the cycle-average margin (11.4%).

Revenue growth

  • 10%

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

    Default: the last 3 years' revenue growth (10% a year, annual reports), fading to 3% by year 5.

  • 8.2%

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

    Default: the last 3 years' revenue growth (10% a year, annual reports), fading to 3% by year 5.

  • 6.5%

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

    Default: the last 3 years' revenue growth (10% a year, annual reports), fading to 3% by year 5.

  • 4.7%

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

    Default: the last 3 years' revenue growth (10% 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 (10% a year, annual reports), fading to 3% by year 5.

Business

  • 11.4%

    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.

  • 16%

    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).

  • 20%

    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).

  • 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

  • 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 0.16, 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 ₩30,152 a share)Now 2.56×₩98,8383.28×₩144,4054.79×₩191,1976.34×

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.
