Dong-A St (170900) Fair Value & Analysis

Healthcare · KR · Market cap 336B KRW

Below-average quality, and screening another 71% overvalued on our models.

What matters now

• The price sits above even our optimistic bull case (22,752 KRW). The favourable scenario is already priced in.
• Weak quality (38/100) 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 (10,611 KRW to 22,752 KRW) leaves room in how you read the outcome.

Analysis

Dong-A St (170900) currently trades at 37,050 KRW, while our model-based Fair Value estimate is 10,611 KRW, implying the stock looks roughly 71.4% overvalued today. The Quality Score stands at 38/100 (below-average quality), in the Healthcare 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, Dong-A St generated revenue of 830B KRW at a net margin of -1.4%. Revenue grew 11.8% year over year. It earns a return on equity of -2.5%. Net debt stands at 366B KRW. Fundamentals as of Aug 13, 2026

Our scenario range runs from 10,611 KRW (bear case) to 22,752 KRW (bull case); at 37,050 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 33% below its 52-week high and 5% above its 52-week low, currently below its 200-day average. For context, the median of 10 Healthcare peers we cover trades at -40% fair-value upside, at -71%, 170900 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.

Widest divergence: Asset-Based (44,652 KRW) versus Multiples (34,371 KRW). Highest evidence: EV/EBITDA (54).

How we calculate Fair Value

Each company is valued through a stack of independent intrinsic-value models (DCF variants, residual-income, multiples and more), blended into one family-balanced consensus and weighted by how much trustworthy data backs it. A separate quality layer scores the fundamentals. Every input is real reported data, nothing guessed.
