What happened
On Oct 22, 2026 the model estimate moved from ₩6,777 to ₩17,640 per share in the base case, a rise of 160%. The bear case is now ₩12,218 and the bull case ₩27,104. The model is still a 5-year discounted cash flow at a 7.8% rate, using trailing data to H1 2026.
No new filings accompany this change, and the data does not explain what drove the revision. The inputs shown (trailing revenue of ₩303.1B, operating income of ₩12.4B, free cash flow of ₩-55.3B) match those in the previous report, so the reason for the change is not available in the data. No smaller recent events are listed.
What it changes for the thesis
The previous report, dated Oct 20, described a sharp price rally alongside weaker fundamentals: operating margin of 4.1% against 8.2% in 2024, and negative free cash flow. Nothing in the data changes those facts. Revenue, margins and the conservative balance sheet (liabilities at 18.5% of equity, borrowings of ₩2.0B against cash of ₩43.8B) are the same.
The thesis that the price implies stronger cash flows than the filed numbers show still holds, but the model revision weakens the size of that gap. The earlier note also said there was no clear earnings driver for the rally, and that remains true. The model change is an assumption or method effect, not new business evidence, as far as the data shows.
What it changes for the valuation
The model estimate, based on the assumptions shown, is now ₩12,218 (bear), ₩17,640 (base) and ₩27,104 (bull) per share. The previous figures were ₩2,752, ₩6,777 and ₩13,912. The share price closed at ₩27,300 on Oct 20, down from ₩30,000 cited in the previous report.
The price is about 55% above the base case, versus roughly 343% before. It is just above the bull case of ₩27,104, whereas earlier it was more than double the bull case. At this price, P/E is 21.9, P/B 1.4 and P/S 1.4, with enterprise value of about ₩352.3B. EV/EBITDA is not available.
The model estimate is not a target and not a signal to act. The size of the revision, 160% with no new filing behind it, shows how sensitive the estimate is to its inputs.
Closing view
The model now places the share price much closer to its estimated range than two days ago, but the data does not show why. The business facts are unchanged: lower margins, negative free cash flow, and a strong balance sheet. A revision of this size without new information suggests treating the model range as wide and assumption-dependent. The gap between price and base case has narrowed, though the price still sits at the top of the range.
