Analysis

Siem Industries S.A (SEMUF) currently trades at $70.00, while our model-based Fair Value estimate is $49.43, implying the stock looks roughly 29.4% overvalued today. The Quality Score stands at 56/100 (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: medium).

Over the trailing twelve months, Siem Industries S.A generated revenue of $225M at a net margin of -1.1%. Revenue declined 48.0% year over year. It earns a return on equity of 4.5%. Net debt stands at $539M. Fundamentals as of Jul 27, 2026

Our scenario range runs from $37.07 (bear case) to $61.79 (bull case); at $70.00, 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 133% above its 52-week low, currently above its 200-day average. For context, the median of 10 Industrials peers we cover trades at 67% fair-value upside, at -29%, SEMUF screens richer 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.

Widest divergence: Economic Profit ($59.02) versus Earnings-Based ($24.79). Highest evidence: Residual Income (76).

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.
