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:
| Low | Typical | High | |
|---|---|---|---|
| Price / book (book value ₩9,680 a share)Now 1.04× | ₩8,7040.90× | ₩11,6351.20× | ₩17,9061.85× |
| Price / earnings (last 12 months: ₩568 a share)Now 17.8× | ₩7,01312.4× | ₩9,69317.1× | ₩23,60141.6× |
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.
