Analysis
Woojinntec Inc (457550) currently trades at 15,300 KRW, while our model-based Fair Value estimate is 5,975 KRW, implying the stock looks roughly 61.0% overvalued today. The Quality Score stands at 50/100 (solid quality), in the Utilities 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: high).
Over the trailing twelve months, Woojinntec Inc generated revenue of 47.4B KRW at a net margin of 13.9%. Revenue grew 29.3% year over year. It earns a return on equity of 13.5%. Fundamentals as of Jul 22, 2026
Our scenario range runs from 4,785 KRW (bear case) to 8,484 KRW (bull case); at 15,300 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 63% below its 52-week high, currently below its 200-day average. For context, the median of 10 Utilities peers we cover trades at -27% fair-value upside, at -61%, 457550 screens richer 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 23 models by family
Widest divergence: Multiples (8,486 KRW) versus Growth DCF (2,908 KRW). Highest evidence: Growth DCF (80).
