What matters now
- The price sits above even our optimistic bull case (3.99 TWD). The favourable scenario is already priced in.
- The large gap to fair value rests on thin data (low evidence): fewer applicable models and a shorter history. Read it with extra caution.
- Solid but not exceptional quality (45/100) and above fair value, neither a clear bargain nor a standout compounder.
- The models converge in a tight band (3.89 TWD to 3.99 TWD), unusually little disagreement for a valuation.

Analysis
Sun Brothers Development Co (3489) currently trades at 25.95 TWD, while our model-based Fair Value estimate is 3.95 TWD, implying the stock looks roughly 84.8% overvalued today. The Quality Score stands at 45/100 (below-average quality), in the Real Estate 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, Sun Brothers Development Co generated revenue of 869M TWD at a net margin of -0.8%. Revenue grew 122.5% year over year. It earns a return on equity of -0.6%. Net debt stands at 1.2B TWD. Fundamentals as of Jul 21, 2026
Our scenario range runs from 3.89 TWD (bear case) to 3.99 TWD (bull case); at 25.95 TWD, 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 near its 52-week high and 57% above its 52-week low, currently above its 200-day average. For context, the median of 10 Real Estate peers we cover trades at 32% fair-value upside, at -85%, 3489 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 4 models by family
Widest divergence: Asset-Based (8.93 TWD) versus Multiples (5.47 TWD). Highest evidence: EV/EBITDA (54).
