Analysis
Tetra Tech, Inc (TTEK) currently trades at $35.44, while our model-based Fair Value estimate is $20.05, implying the stock looks roughly 43.4% overvalued today. The Quality Score stands at 63/100 (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, Tetra Tech, Inc generated revenue of $4.4B at a net margin of 10.0%. Revenue declined 4.9% year over year. It earns a return on equity of 25.7%. Net debt stands at $820M. Fundamentals as of Jul 16, 2026
Our scenario range runs from $15.03 (bear case) to $25.06 (bull case); at $35.44, 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 about 17% below its 52-week high and 37% above its 52-week low, currently above its 200-day average. For context, the median of 10 Industrials peers we cover trades at -45% fair-value upside, at -43%, TTEK 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 26 models by family
Widest divergence: DCF Models ($30.03) versus Dividend Discount ($3.79). Highest evidence: Growth DCF (80).
