It is essentially asking what the stream of expected future cash flows is worth in today’s dollars.</p> <p>For MasTec, the model used is a 2 Stage Free Cash Flow to Equity approach based on cash flow projections. The company’s last twelve months Free Cash Flow is about $322.6 million. Analyst estimates and subsequent extrapolations suggest Free Cash Flow in 2030 of about $1.56b, with interim years such as 2026 and 2027 projected at $803.2 million and $970.9 million respectively, all in $ and based on the provided ten year projection set.</p> <p>After discounting these projected cash flows, the model arrives at an estimated intrinsic value of $319.83 per share. Compared with a current share price of around $412, this DCF output implies MasTec is about 28.9% above the model’s estimate of fair value. On this measure, the stock currently screens as overvalued according to the model.</p> <p><strong>Result: OVERVALUED</strong></p> <p>Our Discounted Cash Flow (DCF) analysis suggests MasTec may be overvalued by 28.9%.

In general, higher expected growth and lower perceived risk can justify a higher P/E, while slower growth or higher risk tend to support a lower, more cautious multiple.</p> <p>MasTec currently trades at a P/E of 71.46x. That compares with an average P/E of 48.04x for the wider Construction industry and a peer average of 45.78x. Simply Wall St also calculates a Fair Ratio of 40.96x, which is the P/E level that might be expected after considering factors such as MasTec’s earnings growth profile, margins, industry, market cap and risk characteristics.</p> <p>This Fair Ratio is more tailored than a simple comparison with industry or peer averages because it adjusts for company specific features rather than treating all stocks in the group as identical. Setting the current P/E of 71.46x against the Fair Ratio of 40.96x suggests the stock is trading materially above what this framework would point to as a more typical level.</p> <p><strong>Result: OVERVALUED</strong></p> <figure><img height="476" src="https://imageproxy.pbkrs.com/https://images.simplywall.st/company/84b86dfb-f73a-408f-b417-bb6043fcccb5/chart/pe-multiple-vs-industry/query-ZGF0ZT0yMDI2LTA1LTEw?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" width="746" original-src="https://imageproxy.pbkrs.com/https://images.simplywall.st/company/84b86dfb-f73a-408f-b417-bb6043fcccb5/chart/pe-multiple-vs-industry/query-ZGF0ZT0yMDI2LTA1LTEw"/><figcaption>NYSE:MTZ P/E Ratio as at May 2026</figcaption></figure> <p>P/E ratios tell one story, but what if the real opportunity lies elsewhere?
