Analysis
STP&I Public Company (STPI) currently trades at 6.30 THB, while our model-based Fair Value estimate is 2.40 THB, implying the stock looks roughly 61.9% overvalued today. The Quality Score stands at 54/100 (solid quality), in the Industrials 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: high).
Over the trailing twelve months, STP&I Public Company generated revenue of 3.2B THB at a net margin of 2.9%. Revenue declined 21.9% year over year. It earns a return on equity of 1.4%. Net debt stands at 3.3B THB. Fundamentals as of Jul 16, 2026
Our scenario range runs from 1.68 THB (bear case) to 2.51 THB (bull case); at 6.30 THB, 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 83% above its 52-week low, currently above its 200-day average. For context, the median of 10 Industrials peers we cover trades at -72% fair-value upside, at -62%, STPI 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.
