- Too wide to call
Reverse DCF: Today's price implies revenue growth of more than 25%/yr. Above about 25% a year the reverse-DCF stops being informative. It solves for revenue growth alone — holding margins, capital intensity and the forecast horizon fixed — so a price well above our cash-flow model's value has nowhere to go but growth, and the solver returns a rate the model can't reconcile. Read it as "the price implies growth we can't justify", not as a forecast.

Why MTZ gets a range, not one number
At a recent price of $190.91, MasTec, Inc. (MTZ) sits inside a range too wide to call either way: our valuation lenses put the business somewhere between $75.96 and $276.73 per share. They disagree too widely for us to state a single fair value. We publish the range rather than a midpoint because a number that precise would claim more than the methods can support. This is an educational model, not a price target or a recommendation.
Read the full reasoning
The valuation discounts MasTec, Inc.'s projected free cash flows at a weighted-average cost of capital (WACC) of 12.6%, with a long-run terminal growth rate of 2.5%. About 66% of the enterprise value comes from the terminal value — the portion beyond the explicit forecast window — which is typical for a stable, cash-generative business and a reminder that small changes in the discount rate or terminal growth assumption swing the intrinsic value meaningfully.
Running the DCF in reverse — solving for the growth the current price already assumes — MTZ would need sustained revenue growth of more than 25%/yr to justify today's price, against about 13.5% a year compounded in our base case. We don't quote a precise figure here, because past about 25% a year the reverse-DCF stops being informative: it solves for revenue growth alone, holding margins, capital intensity and the forecast horizon fixed, so a price well above our fair value has nowhere to go but growth. The honest reading is that the price implies growth this model can't reconcile — not that we forecast it.
Sensitivity matters more than any single number. Across a reasonable band of discount-rate assumptions, MTZ's modeled DCF value ranges from about $77.52 to $144.71 per share. If that range still sits below today's price, the market is optimistic relative to the model across the whole band; if it brackets the price, the stock is roughly fairly valued on our assumptions. Use the interactive slider to see exactly where your own cost-of-capital view lands.
How to read this page: the DCF fair value is what MasTec, Inc. would be worth if its cash flows grow as modeled and are discounted at the stated WACC. The assumptions table shows every input and its source; the reverse-DCF shows what the market believes; the sensitivity band shows how fragile the answer is. None of this is investment advice — it is a transparent, auditable framework for forming your own view of MTZ's intrinsic value. Figures update as new filings and prices come in.

TickerWorth's fair-value range for MasTec, Inc. (MTZ) is $75.96 – $276.73 against a market price of $190.91. Too wide to call. We publish a range here, not one number, so we do not call it over- or undervalued. This is a model estimate, not investment advice.
MasTec (MTZ) DCF valuation and fair value
Our fair-value range for MasTec, Inc. (MTZ) is $75.96 – $276.73, built on a 12.6% discount rate (WACC) and 2.5% terminal growth. It blends our discounted-cash-flow model with other valuation lenses. Every assumption is listed on this page with its source.
What growth is priced into MasTec stock?
Today's price implies revenue growth of more than 25%/yr. Above about 25% a year the reverse-DCF stops being informative. It solves for revenue growth alone — holding margins, capital intensity and the forecast horizon fixed — so a price well above our cash-flow model's value has nowhere to go but growth, and the solver returns a rate the model can't reconcile. Read it as "the price implies growth we can't justify", not as a forecast. This is a reverse DCF: it holds our cash-flow model's other inputs and solves for the revenue growth that makes the model equal today's price of $190.91. A model estimate, not investment advice.
