Approach 1: MasTec Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model estimates what a stock could be worth by projecting the company’s future cash flows and then discounting them back to today’s value using a required return. It is essentially asking what those future dollars are worth in today’s terms.

For MasTec, the model used is a 2 Stage Free Cash Flow to Equity approach. The latest twelve month free cash flow stands at about $322.6 million. Analysts have provided detailed free cash flow estimates out to 2028. Beyond that point, Simply Wall St extrapolates cash flows, reaching a projected free cash flow of $1.7 billion in 2030.

When all of these projected cash flows are discounted back, the model arrives at an estimated intrinsic value of $372.80 per share. Compared with the recent share price of about $362.97, the DCF suggests the stock trades at roughly a 2.6% discount, which is a small gap and not a strong signal either way on its own.

Result: ABOUT RIGHT

MasTec is fairly valued according to our Discounted Cash Flow (DCF), but this can change at a moment's notice. Track the value in your watchlist or portfolio and be alerted on when to act.

Approach 2: MasTec Price vs Earnings

For a profitable company like MasTec, the P/E ratio is a useful shortcut because it links what you pay for the stock to the earnings the business is currently generating. It helps you see how many dollars investors are willing to pay for each dollar of earnings.

What counts as a “normal” P/E depends a lot on how quickly earnings are expected to grow and how risky those earnings are. Higher growth and lower perceived risk usually justify a higher multiple, while slower growth or higher risk usually calls for a lower one.

MasTec currently trades on a P/E of 62.9x. That sits above the Construction industry average P/E of 46.6x and the peer average of 47.0x, so on simple comparisons the stock is priced more expensively than many peers.

Simply Wall St’s “Fair Ratio” aims to refine that picture. It is a proprietary estimate of what P/E might be reasonable for MasTec, taking into account factors like its earnings growth profile, industry, profit margins, market cap and company specific risks. Because it incorporates these drivers directly, it can be more informative than a plain comparison with industry and peer averages.

MasTec’s Fair Ratio is 40.4x, which is meaningfully below the current 62.9x P/E, indicating the stock screens as expensive on this measure.

Upgrade Your Decision Making: Choose your MasTec Narrative

Earlier it was mentioned that there is an even better way to understand valuation. Narratives on Simply Wall St let you attach a clear story about MasTec to the numbers by linking your view of its future revenue, earnings and margins to a financial forecast, a Fair Value, and a simple comparison with today’s price that updates automatically when new news or earnings arrive. For example, one investor might side with a more optimistic MasTec Narrative that points to a Fair Value around US$545.0 based on higher growth and a 42.4x future P/E, while another might choose a more cautious Narrative closer to US$325.05 with slower growth and a 39.4x future P/E.
