Analysis

Transportadora de Gas del Sur S.A (TGS) currently trades at $28.79, while our model-based Fair Value estimate is $24.82, implying the stock looks roughly 13.8% overvalued today. The Quality Score stands at 57/100 (solid quality), in the Energy 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, Transportadora de Gas del Sur S.A generated revenue of $1.8T at a net margin of 24.7%. Revenue grew 13.2% year over year. It earns a return on equity of 14.3%. Net debt stands at $869B. Fundamentals as of Jul 5, 2026

Our scenario range runs from $17.22 (bear case) to $39.74 (bull case); at $28.79, the current price sits within 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 21% below its 52-week high and 46% above its 52-week low, currently below its 200-day average. For context, the median of 10 Energy peers we cover trades at -11% fair-value upside, at -14%, TGS 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.
