Fair value as of: Aug 13, 2026
From 26 valuation models · updated today
Fair value updated Aug 13, 2026, revised from $101.43 to $100.00 (−1.4%) since Jul 19, 2026. Share price −21.6% over the past month.
A solid business, but screening 65% overvalued on our models.
What matters now
- The price sits above even our optimistic bull case ($132.56). The favourable scenario is already priced in.
- The model range is unusually wide ($39.93 to $132.56). The outcome hinges heavily on assumptions, so read the point estimate with caution.
- Solid but not exceptional quality (56/100) and above fair value, neither a clear bargain nor a standout compounder.

Analysis
MasTec, Inc (MTZ) currently trades at $286.11, while our model-based Fair Value estimate is $100.00, implying the stock looks roughly 65.1% 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: high).
Over the trailing twelve months, MasTec, Inc generated revenue of $15.3B at a net margin of 3.0%. Revenue grew 34.5% year over year. It earns a return on equity of 15.0%. Net debt stands at $2.4B. Fundamentals as of Aug 13, 2026
Our scenario range runs from $39.93 (bear case) to $132.56 (bull case); at $286.11, 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 last reported earnings sit well below what analysts expect (earnings in transition, for example after write-downs or an earnings dip); whether the stock is cheap or expensive hinges on the expected recovery actually arriving. Read the fair value with that caveat. The share trades about 35% below its 52-week high and 86% above its 52-week low, currently above its 200-day average. For context, the median of 10 Industrials peers we cover trades at -34% fair-value upside, at -65%, MTZ 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.
All 26 models by family
Widest divergence: Growth Earnings ($115.57) versus Dividend Discount ($1.44). Highest evidence: Growth DCF (80).
