Mistras Group, Inc. (NYSE:MG) shares have had a horrible month, losing 26% after a relatively good period beforehand. Looking at the bigger picture, even after this poor month the stock is up 44% in the last year.

Although its price has dipped substantially, Mistras Group may still be sending bullish signals at the moment with its price-to-sales (or "P/S") ratio of 0.4x, since almost half of all companies in the Professional Services industry in the United States have P/S ratios greater than 1.6x and even P/S higher than 4x are not unusual. However, the P/S might be low for a reason and it requires further investigation to determine if it's justified.

What Does Mistras Group's P/S Mean For Shareholders?

Mistras Group could be doing better as it's been growing revenue less than most other companies lately. It seems that many are expecting the uninspiring revenue performance to persist, which has repressed the growth of the P/S ratio. If this is the case, then existing shareholders will probably struggle to get excited about the future direction of the share price.

How Is Mistras Group's Revenue Growth Trending?

Mistras Group's P/S ratio would be typical for a company that's only expected to deliver limited growth, and importantly, perform worse than the industry.

If we review the last year of revenue growth, the company posted a worthy increase of 6.8%. The latest three year period has also seen a 11% overall rise in revenue, aided somewhat by its short-term performance. Accordingly, shareholders would have probably been satisfied with the medium-term rates of revenue growth.

Turning to the outlook, the next year should generate growth of 1.4% as estimated by the dual analysts watching the company. With the industry predicted to deliver 6.7% growth, the company is positioned for a weaker revenue result.

With this information, we can see why Mistras Group is trading at a P/S lower than the industry. Apparently many shareholders weren't comfortable holding on while the company is potentially eyeing a less prosperous future.

The Final Word

Mistras Group's P/S has taken a dip along with its share price. Typically, we'd caution against reading too much into price-to-sales ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

As we suspected, our examination of Mistras Group's analyst forecasts revealed that its inferior revenue outlook is contributing to its low P/S. Shareholders' pessimism on the revenue prospects for the company seems to be the main contributor to the depressed P/S. The company will need a change of fortune to justify the P/S rising higher in the future.
