Cycle options

Margin path

Revenue growth

  • -1.3%

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

    Default: the last 3 years' revenue growth (-2.7% a year, annual reports), fading to 3% by year 5.

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

  • 3%

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

Business

  • 7.4%

    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.

  • 3.8%

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

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

  • -1%

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

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

  • 0.6

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

  • 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 ₩7,443 a share)Now 0.44×₩3,0210.41×₩4,1540.56×₩7,2350.97×

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.
