Those holding Pentanet Limited (ASX:5GG) shares would be relieved that the share price has rebounded 38% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 20% over that time.

Although its price has surged higher, it's still not a stretch to say that Pentanet's price-to-sales (or "P/S") ratio of 0.7x right now seems quite "middle-of-the-road" compared to the Telecom industry in Australia, where the median P/S ratio is around 1x. 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.

What Does Pentanet's P/S Mean For Shareholders?

Revenue has risen at a steady rate over the last year for Pentanet, which is generally not a bad outcome. One possibility is that the P/S is moderate because investors think this good revenue growth might only be parallel to the broader industry in the near future. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's not quite in favour.

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

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

Retrospectively, the last year delivered a decent 4.1% gain to the company's revenues. This was backed up an excellent period prior to see revenue up by 55% in total over the last three years. So we can start by confirming that the company has done a great job of growing revenues over that time.

Comparing that recent medium-term revenue trajectory with the industry's one-year growth forecast of 5.2% shows it's noticeably more attractive.

In light of this, it's curious that Pentanet's P/S sits in line with the majority of other companies. It may be that most investors are not convinced the company can maintain its recent growth rates.

The Bottom Line On Pentanet's P/S

Its shares have lifted substantially and now Pentanet's P/S is back within range of the industry median. 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.

We didn't quite envision Pentanet's P/S sitting in line with the wider industry, considering the revenue growth over the last three-year is higher than the current industry outlook. When we see strong revenue with faster-than-industry growth, we can only assume potential risks are what might be placing pressure on the P/S ratio. While recent revenue trends over the past medium-term suggest that the risk of a price decline is low, investors appear to see the likelihood of revenue fluctuations in the future.

You need to take note of risks, for example - Pentanet has 3 warning signs (and 1 which shouldn't be ignored) we think you should know about.

Of course, profitable companies with a history of great earnings growth are generally safer bets. So you may wish to see this free collection of other companies that have reasonable P/E ratios and have grown earnings strongly.
