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.

Price vs Fair Value (5 years)

White line = price, green steps = our fair value per fiscal year, dashed = 300-day average. As of Sep 1, 2026.

How to read this chart

60‑month range $47.60 – $437.51 · fair‑value band $39.93 – $132.56 · the $232.28 price screens above the $100.00 fair value. Green steps = our fair value per fiscal year (point-in-time, no hindsight). 3 fiscal years are left out: there the valuation rested on only a fraction of the usual models. Dashed = 300-day average. As of Sep 1, 2026.

Analysis

MasTec Inc (MTZ) currently trades at $232.28, while our model-based Fair Value estimate is $100.00, implying the stock looks roughly 132.3% overvalued today. The Quality Score stands at 56/100 (solid quality), in the Industrials sector. Bull case: the Growth Earnings group reads highest at a median of $115.57 per share, and 0 of the 26 models we run sit above the $232.28 price. Bear case: the Asset-Based group reads lowest at $27.64, and 26 of the 26 models stay below the price. Evidence for this calculation is 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 Sep 1, 2026

Our scenario range runs from $39.93 (bear case) to $132.56 (bull case); at $232.28, 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 47% below its 52-week high and 51% above its 52-week low, currently below its 200-day average. For context, the median of 10 Industrials peers we cover trades at −46% fair-value upside, at −57%, MTZ screens richer than that median.

Fair Value models

This estimate rests on fiscal year 2025 figures, and about 8 months have passed since. In that time the company retained roughly $3.87 per share, which is 3.9 % of the fair value. The fair value deliberately does not add this in: the models value reported figures, not a projection.

Each model estimates fair value its own way; the Fair Value above is the evidence-weighted, family-balanced 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. Every input is real reported data, nothing guessed.

Widest divergence: Growth Earnings ($115.57) versus Dividend Discount ($1.44). Highest evidence: EPV (74).
