Fullhome Development Co (5345) Fair Value & Analysis
Technology · TW · Market cap 952M TWD
Fair value as of: Jul 23, 2026
From 3 valuation models · updated 18 days ago
Share price −5.6% over the past month.
Below-average quality, and screening another 70% overvalued on our models.
What matters now
- The price sits above even our optimistic bull case (10.20 TWD). The favourable scenario is already priced in.
- The model range is unusually wide (3.45 TWD to 10.20 TWD). The outcome hinges heavily on assumptions, so read the point estimate with caution.
- 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 (46/100) and above fair value, neither a clear bargain nor a standout compounder.

Analysis
Fullhome Development Co (5345) currently trades at 22.70 TWD, while our model-based Fair Value estimate is 6.80 TWD, implying the stock looks roughly 70.0% overvalued today. The Quality Score stands at 46/100 (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, Fullhome Development Co generated revenue of 28.2M TWD at a net margin of -36.3%. Revenue grew 282.4% year over year. It earns a return on equity of -4.7%. Net debt stands at 8.8M TWD. Fundamentals as of Jul 23, 2026
Our scenario range runs from 3.45 TWD (bear case) to 10.20 TWD (bull case); at 22.70 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 about 40% below its 52-week high and 24% above its 52-week low, currently below its 200-day average. For context, the median of 10 Technology peers we cover trades at -73% fair-value upside, at -70%, 5345 screens cheaper 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 3 models by family
Widest divergence: Dividend Discount (5.08 TWD) versus Asset-Based (3.80 TWD). Highest evidence: Gordon GGM (70).
