SANGBO Corp (027580) Fair Value & Analysis
Technology · KR · Market cap 16.2B KRW
Fair value as of: Aug 17, 2026
From 1 valuation models · updated 3 days ago
Share price +15.5% over the past month.
Below-average quality, and screening another 80% overvalued on our models.
What matters now
- The price sits above even our optimistic bull case (426.00 KRW). The favourable scenario is already priced in.
- Weak quality (41/100) and above fair value at the same time, the margin of safety is missing on both counts.
- The large gap to fair value rests on thin data (low evidence): fewer applicable models and a shorter history. Read it with extra caution.
- A fairly wide model range (224.93 KRW to 426.00 KRW) leaves room in how you read the outcome.

Analysis
SANGBO Corp (027580) currently trades at 1,663 KRW, while our model-based Fair Value estimate is 340.80 KRW, implying the stock looks roughly 79.5% overvalued today. The Quality Score stands at 41/100 (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: low).
Over the trailing twelve months, SANGBO Corp generated revenue of 120B KRW at a net margin of 3.9%. Revenue declined 25.1% year over year. Net debt stands at 28.4B KRW. Fundamentals as of Aug 17, 2026
Our scenario range runs from 224.93 KRW (bear case) to 426.00 KRW (bull case); at 1,663 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 72% below its 52-week high and 7% above its 52-week low, currently below its 200-day average. For context, the median of 10 Technology peers we cover trades at 10% fair-value upside, at -80%, 027580 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.
