What matters now
- The rarer combination: high quality (72/100) AND below fair value. That earns a closer look rather than a quick verdict.
- The price is below even our cautious bear case (5.62 THB). The market is more pessimistic than our downside scenario.
- The model range is unusually wide (5.62 THB to 16.52 THB). The outcome hinges heavily on assumptions, so read the point estimate with caution.

Analysis
Interroyal Engineering Public Company (IROYAL) currently trades at 4.58 THB, while our model-based Fair Value estimate is 10.03 THB, implying the stock looks roughly 119.0% undervalued today. The Quality Score stands at 72/100 (solid quality), in the Industrials sector. Bull case: trading below our estimate, it may offer upside if the fundamentals hold. Bear case: a low price can be a value trap when quality is weak or the data is thin (evidence: high), always confirm before acting.
Over the trailing twelve months, Interroyal Engineering Public Company generated revenue of 551M THB at a net margin of 28.7%. Revenue grew 151.8% year over year. It earns a return on equity of 27.0%. The stock trades on a trailing P/E of 6.6. Fundamentals as of Jul 16, 2026
Our scenario range runs from 5.62 THB (bear case) to 16.52 THB (bull case); at 4.58 THB, the current price sits below 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 23% below its 52-week high and 56% above its 52-week low, currently below its 200-day average. For context, the median of 10 Industrials peers we cover trades at -48% fair-value upside, at 119%, IROYAL 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 24 models by family
Widest divergence: Growth Earnings (26.95 THB) versus Asset-Based (1.84 THB). Highest evidence: Residual Income (76).
