With a price-to-sales (or "P/S") ratio of 0.2x Muscle Maker, Inc. (NASDAQ:GRIL) may be sending bullish signals at the moment, given that almost half of all the Hospitality companies in the United States have P/S ratios greater than 1.7x and even P/S higher than 4x are not unusual. Although, it's not wise to just take the P/S at face value as there may be an explanation why it's limited.

How Has Muscle Maker Performed Recently?

Muscle Maker certainly has been doing a great job lately as it's been growing its revenue at a really rapid pace. One possibility is that the P/S ratio is low because investors think this strong revenue growth might actually underperform the broader industry in the near future. If that doesn't eventuate, then existing shareholders have reason to be quite optimistic about the future direction of the share price.

We don't have analyst forecasts, but you can see how recent trends are setting up the company for the future by checking out our free report on Muscle Maker's earnings, revenue and cash flow.

What Are Revenue Growth Metrics Telling Us About The Low P/S?

There's an inherent assumption that a company should underperform the industry for P/S ratios like Muscle Maker's to be considered reasonable.

Taking a look back first, we see that the company's revenues underwent some rampant growth over the last 12 months. The amazing performance means it was also able to deliver huge revenue growth over the last three years. So we can start by confirming that the company has done a tremendous job of growing revenue over that time.

Comparing that recent medium-term revenue trajectory with the industry's one-year growth forecast of 31% shows it's noticeably more attractive.

With this in mind, we find it intriguing that Muscle Maker's P/S isn't as high compared to that of its industry peers. Apparently some shareholders believe the recent performance has exceeded its limits and have been accepting significantly lower selling prices.

The Bottom Line On Muscle Maker's P/S

It's argued the price-to-sales ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

We're very surprised to see Muscle Maker currently trading on a much lower than expected P/S since its recent three-year growth is higher than the wider industry forecast. When we see strong revenue with faster-than-industry growth, we assume there are some significant underlying risks to the company's ability to make money which is applying downwards pressure on the P/S ratio. At least price risks look to be very low if recent medium-term revenue trends continue, but investors seem to think future revenue could see a lot of volatility.
