Prosper Engineering Public Company (PROS) Fair Value & Analysis

Industrials · TH · Market cap 96.0M THB

Below-average quality, and screening another 35% overvalued on our models.

What matters now

• The price sits above even our optimistic bull case (0.1600 THB). The favourable scenario is already priced in.
• Weak quality (31/100) 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 (0.0800 THB to 0.1600 THB) leaves room in how you read the outcome.

Analysis

Prosper Engineering Public Company (PROS) currently trades at 0.1700 THB, while our model-based Fair Value estimate is 0.1100 THB, implying the stock looks roughly 35.3% overvalued today. The Quality Score stands at 31/100 (below-average 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: low).

Over the trailing twelve months, Prosper Engineering Public Company generated revenue of 618M THB at a net margin of -25.3%. Revenue declined 65.1% year over year. It earns a return on equity of -99.2%. Net debt stands at 179M THB. Fundamentals as of Jul 11, 2026

Our scenario range runs from 0.0800 THB (bear case) to 0.1600 THB (bull case); at 0.1700 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. For context, the median of 10 Industrials peers we cover trades at -45% fair-value upside, at -35%, PROS 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.

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.
