Analysis
Korea Airport Service Co (005430) currently trades at 92,400 KRW, while our model-based Fair Value estimate is 206,872 KRW, implying the stock looks roughly 123.9% undervalued today. The Quality Score stands at 58/100 (solid quality), in the Industrials sector. Bull case: trading below our estimate, it may offer upside if the fundamentals hold. Bear case: a low price can be a value trap when quality is weak or the data is thin (evidence: high), always confirm before acting.
Over the trailing twelve months, Korea Airport Service Co generated revenue of 684B KRW at a net margin of 6.6%. Revenue grew 13.5% year over year. It earns a return on equity of 11.3%. Fundamentals as of Jul 22, 2026
Our scenario range runs from 121,015 KRW (bear case) to 299,803 KRW (bull case); at 92,400 KRW, the current price sits below 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 1% below its 52-week high and 82% above its 52-week low, currently above its 200-day average. For context, the median of 10 Industrials peers we cover trades at -29% fair-value upside, at 124%, 005430 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.
All 17 models by family
Widest divergence: DCF Models (252,431 KRW) versus Dividend Discount (15,625 KRW). Highest evidence: Residual Income (76).
