Fair value as of: Jul 22, 2026

From 13 valuation models · updated 19 days ago

Fair value updated Jul 22, 2026, revised from 14,414 KRW to 14,316 KRW (−0.7%) since Jul 6, 2026. Share price −4.9% over the past month.

A solid business, but screening 27% overvalued on our models.

What matters now

  • The price sits above even our optimistic bull case (16,187 KRW). The favourable scenario is already priced in.
  • Solid but not exceptional quality (53/100) and above fair value, neither a clear bargain nor a standout compounder.
  • The models converge in a tight band (14,316 KRW to 16,187 KRW), unusually little disagreement for a valuation.

Analysis

IS DongSeo Co (010780) currently trades at 19,590 KRW, while our model-based Fair Value estimate is 14,316 KRW, implying the stock looks roughly 26.9% overvalued today. The Quality Score stands at 53/100 (solid quality), in the Industrials sector. Bear case: priced above our estimate, the market already discounts strong expectations. Bull case: above-average quality can justify a premium, the entry price still matters most (evidence: medium).

Over the trailing twelve months, IS DongSeo Co generated revenue of 1.4T KRW at a net margin of 7.1%. Revenue grew 46.1% year over year. It earns a return on equity of 5.3%. Net debt stands at 1.1T KRW. Fundamentals as of Jul 22, 2026

Our scenario range runs from 14,316 KRW (bear case) to 16,187 KRW (bull case); at 19,590 KRW, the current price sits above that range. Bear and bull are the same models run on conservative and optimistic assumptions (margins, growth, valuation multiples), so a plausible valuation range, not a price target. The share trades about 43% below its 52-week high and 17% above its 52-week low, currently below its 200-day average. For context, the median of 10 Industrials peers we cover trades at -45% fair-value upside, at -27%, 010780 screens cheaper than that median.

Fair Value models

Each model estimates fair value its own way; the Fair Value above is the evidence-weighted blend. Evidence (0–100) measures how completely this model’s inputs are available: well-fed models carry more weight in the blend. The spread across models is intentional, each one stresses a different value driver; dividend models, for instance, come out structurally low when payout is small.

Model Bear Bear = the cautious scenario: the same model computed with conservative anchors (lower growth, margins and valuation multiples). Together with Bull it frames a plausible valuation range, not a price target.BaseBull Bull = the optimistic scenario: the same model computed with favourable anchors (higher growth, margins and valuation multiples). Together with Bear it frames a plausible valuation range, not a price target. Evidence
