Analysis
Mercury Corporation (100590) currently trades at 3,755 KRW, while our model-based Fair Value estimate is 1,196 KRW, implying the stock looks roughly 68.2% overvalued today. The Quality Score stands at 48/100 (below-average quality), in the Technology 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, Mercury Corporation generated revenue of 128B KRW at a net margin of 0.9%. Revenue grew 20.9% year over year. It earns a return on equity of 1.0%. Net debt stands at 7.2B KRW. Fundamentals as of Jul 22, 2026
Our scenario range runs from 783.03 KRW (bear case) to 1,609 KRW (bull case); at 3,755 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 71% below its 52-week high and 25% above its 52-week low, currently below its 200-day average. For context, the median of 10 Technology peers we cover trades at -61% fair-value upside, at -68%, 100590 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 10 models by family
Widest divergence: Growth DCF (9,216 KRW) versus Multiples (2,576 KRW). Highest evidence: Growth DCF (80).
