What matters now
- The price sits above even our optimistic bull case (¥10.29). The favourable scenario is already priced in.
- Weak quality (42/100) 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.

60‑month range ¥15.18 – ¥114.70 · fair‑value band ¥6.45 – ¥10.29 · the ¥57.94 price screens above the ¥10.07 fair value. Dashed = 300-day average. As of Aug 20, 2026.
Analysis
Suzhou TA&A Ultra Clean Technology Co Ltd (300390) currently trades at ¥57.94, while our model-based Fair Value estimate is ¥10.07, implying the stock looks roughly 475.4% overvalued today. The Quality Score stands at 42/100 (below-average quality), in the Industrials sector. Bull case: the Growth Earnings group reads highest at a median of ¥21.84 per share, and 0 of the 16 models we run sit above the ¥57.94 price. Bear case: the Economic Profit group reads lowest at ¥5.40, and 16 of the 16 models stay below the price. Evidence for this calculation is low.
Over the trailing twelve months, Suzhou TA&A Ultra Clean Technology Co Ltd generated revenue of 9.1B CNY at a net margin of 14.5%. Revenue grew 89.6% year over year. It earns a return on equity of 9.2%. Net debt stands at 2.0B CNY. Fundamentals as of Aug 20, 2026
Our scenario range runs from ¥6.45 (bear case) to ¥10.29 (bull case); at ¥57.94, 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 51% below its 52-week high and 238% above its 52-week low, currently above its 200-day average. For context, the median of 10 Industrials peers we cover trades at −31% fair-value upside, at −83%, 300390 screens richer than that median.
Fair Value models
This estimate rests on fiscal year 2025 figures, and about 8 months have passed since. In that time the company retained roughly ¥1.07 per share, which is 9.3 % of the fair value. The fair value deliberately does not add this in: the models value reported figures, not a projection.
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted, family-balanced 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. Every input is real reported data, nothing guessed.
All 16 models by family
Widest divergence: Growth Earnings (¥21.84) versus Economic Profit (¥5.40). Highest evidence: EPV (74).

Quality Score breakdown
Of which business quality 39 · Market factors (momentum, volatility) 59
Non-valuation factor families (profitability, growth, cashflow, financial strength, momentum …), each academically grounded. Valuation itself sits in the Fair Value and is deliberately excluded here to avoid double-counting.
All values are scores from 0 to 100 (100 = best against fixed, research-based bands), not percentages. The three market factors (momentum, 52-week proximity, low volatility) are displayed but carry zero weight in the headline number: market sentiment is not a business property.
