MasTec, Inc. (NYSE:MTZ) shares have had a really impressive month, gaining 31% after a shaky period beforehand. Looking back a bit further, it's encouraging to see the stock is up 85% in the last year.

Although its price has surged higher, you could still be forgiven for feeling indifferent about MasTec's P/S ratio of 0.8x, since the median price-to-sales (or "P/S") ratio for the Construction industry in the United States is also close to 1.2x. Although, it's not wise to simply ignore the P/S without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

How MasTec Has Been Performing

MasTec could be doing better as it's been growing revenue less than most other companies lately. One possibility is that the P/S ratio is moderate because investors think this lacklustre revenue performance will turn around. 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?

MasTec's P/S ratio would be typical for a company that's only expected to deliver moderate growth, and importantly, perform in line with the industry.

If we review the last year of revenue growth, the company posted a worthy increase of 11%. Pleasingly, revenue has also lifted 72% in aggregate from three years ago, partly thanks to the last 12 months of growth. So we can start by confirming that the company has done a great job of growing revenues over that time.

Looking ahead now, revenue is anticipated to climb by 6.6% per annum during the coming three years according to the twelve analysts following the company. That's shaping up to be materially lower than the 11% each year growth forecast for the broader industry.

With this in mind, we find it intriguing that MasTec's P/S is closely matching its industry peers. It seems most investors are ignoring the fairly limited growth expectations and are willing to pay up for exposure to the stock. These shareholders may be setting themselves up for future disappointment if the P/S falls to levels more in line with the growth outlook.

What We Can Learn From MasTec's P/S?

MasTec's stock has a lot of momentum behind it lately, which has brought its P/S level with the rest of the industry. Using the price-to-sales ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

Given that MasTec's revenue growth projections are relatively subdued in comparison to the wider industry, it comes as a surprise to see it trading at its current P/S ratio. At present, we aren't confident in the P/S as the predicted future revenues aren't likely to support a more positive sentiment for long. A positive change is needed in order to justify the current price-to-sales ratio.
