Valuation model · Discounted cash flow (DCF)

We use a 5-year discounted cash flow: the value of the cash the business is expected to produce, in today's money.

Fair value per share

With these assumptions the model gives no positive value.

Enterprise value: −₩40B
Equity value: −₩19B
WACC: 7.4%

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 gives no positive value at these assumptions. What we can see:

To match today's price of ₩2,370, the model needs an operating margin of 49.6% every year (it uses −20.0%).
Margins ranged from −100.9% to −10.9% 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.
100% 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.

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

Bear / Base / Bull

Bear: —
Base: —
Bull: —

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

Assumptions

Cycle options

Margin path

Every year uses the cycle-average margin (−20.0%).

Revenue growth

Revenue growth, year 1-10%
How much sales grow that year, compared with the year before.
Default: the last 3 years' revenue growth (-23.2% a year, annual reports), fading to 3% by year 5.
Revenue growth, year 2-6.7%
How much sales grow that year, compared with the year before.
Default: the last 3 years' revenue growth (-23.2% a year, annual reports), fading to 3% by year 5.
Revenue growth, year 3-3.5%
How much sales grow that year, compared with the year before.
Default: the last 3 years' revenue growth (-23.2% a year, annual reports), fading to 3% by year 5.
Revenue growth, year 4-0.2%
How much sales grow that year, compared with the year before.
Default: the last 3 years' revenue growth (-23.2% a year, annual reports), fading to 3% by year 5.
Revenue growth, year 53%
How much sales grow that year, compared with the year before.
Default: the last 3 years' revenue growth (-23.2% a year, annual reports), fading to 3% by year 5.

Business

EBIT margin-20%
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.
Tax rate27.5%
Share of operating profit paid as corporate tax.
Default: Korea's top corporate tax rate (25%) plus 10% local income tax.
Depreciation & amortisation2.6%
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).
Capital spending3.3%
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).
Working capital-10%
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

Terminal growth2%
How fast cash flows keep growing every year after year 5.
Default: about Korea's long-run inflation plus real growth.
Risk-free rate4.11%
Yield on Korea's 10-year government bond: the return with almost no risk.
Default: Korea Treasury Bond 10-year yield on 2026-10-28.
Beta0.6
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 -0.21, adjusted toward 1 and kept between 0.6 and 2.0.
Equity risk premium5.5%
The extra return investors want for owning shares instead of bonds.
Default: a typical premium for Korean shares.
Cost of debt (before tax)5.61%
The interest rate the company would pay to borrow.
Default: the 10-year yield plus a 1.5% credit spread.

Starting point

Revenue (TTM to H1 2026): ₩19B
Net debt (borrowings and leases − cash and deposits): −₩20B
Shares: 48,972,158
Share price: ₩2,370
Market cap: ₩116B

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.

Terminal value −₩43B, worth −₩30B today: 75% of enterprise value. It assumes spending settles at 110% of depreciation once growth slows to the terminal rate.

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:

	Low	Typical	High
Price / book (book value ₩851 a share)Now 2.78×	₩1,8712.20×	₩2,4092.83×	₩3,8884.57×

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.

Sensitivity
