There wouldn't be many who think MasTec, Inc.'s (NYSE:MTZ) price-to-sales (or "P/S") ratio of 0.8x is worth a mention when the median P/S for the Construction industry in the United States is similar at about 0.9x. While this might not raise any eyebrows, if the P/S ratio is not justified investors could be missing out on a potential opportunity or ignoring looming disappointment.

How MasTec Has Been Performing

With revenue growth that's inferior to most other companies of late, MasTec has been relatively sluggish. It might be that many expect the uninspiring revenue performance to strengthen positively, which has kept the P/S ratio from falling. However, if this isn't the case, investors might get caught out paying too much for the stock.

Is There Some Revenue Growth Forecasted For MasTec?

The only time you'd be comfortable seeing a P/S like MasTec's is when the company's growth is tracking the industry closely.

Taking a look back first, we see that the company managed to grow revenues by a handy 2.6% last year. Pleasingly, revenue has also lifted 55% in aggregate from three years ago, partly thanks to the last 12 months of growth. Therefore, it's fair to say the revenue growth recently has been superb for the company.

Turning to the outlook, the next three years should generate growth of 8.1% per year as estimated by the analysts watching the company. Meanwhile, the rest of the industry is forecast to expand by 8.9% per year, which is not materially different.

With this information, we can see why MasTec is trading at a fairly similar P/S to the industry. It seems most investors are expecting to see average future growth and are only willing to pay a moderate amount for the stock.

The Final Word

While the price-to-sales ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of revenue expectations.

Our look at MasTec's revenue growth estimates show that its P/S is about what we expect, as both metrics follow closely with the industry averages. At this stage investors feel the potential for an improvement or deterioration in revenue isn't great enough to push P/S in a higher or lower direction. Unless these conditions change, they will continue to support the share price at these levels.
