Is MTZ overvalued in 2026?
MasTec Inc (MTZ) currently trades at $421.37 per share with a market capitalization of $28,681,368,000.00. Based on our multi-factor framework, the stock trades at a fair valuation with a Smart Value Score of 63/100. This score blends growth quality, financial health, and price attractiveness into a single institutional-grade read.
The stock trades at a P/E ratio of 63.7x, below its 5-year median of 66.1x. The PEG ratio of 1.64 points to a price that reasonably reflects expected earnings growth.

A standard DCF model does not produce reliable output for MTZ under current conditions. For unprofitable or near-breakeven companies, revenue-based multiples such as EV/Sales and historical P/S percentile are more informative than intrinsic value calculations.
The Piotroski F-Score of 5/9 puts financial quality in a middling range, neither a standout strength nor an obvious red flag.
Bottom line: MTZ trades at a fair valuation on our framework, with a Smart Value Score of 63/100. The valuation is defensible but offers no obvious bargain. Patience or a better entry price may reward disciplined buyers.
