Despite an already strong run, Frontier Group Holdings, Inc. (NASDAQ:ULCC) shares have been powering on, with a gain of 27% in the last thirty days. The last 30 days bring the annual gain to a very sharp 27%.

In spite of the firm bounce in price, it's still not a stretch to say that Frontier Group Holdings' price-to-sales (or "P/S") ratio of 0.4x right now seems quite "middle-of-the-road" compared to the Airlines industry in the United States, where the median P/S ratio is around 0.6x. 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 Frontier Group Holdings' P/S Mean For Shareholders?

Frontier Group Holdings 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. You'd really hope so, otherwise you're paying a relatively elevated price for a company with this sort of growth profile.

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

There's an inherent assumption that a company should be matching the industry for P/S ratios like Frontier Group Holdings' to be considered reasonable.

Retrospectively, the last year delivered virtually the same number to the company's top line as the year before. Still, the latest three year period has seen an excellent 113% overall rise in revenue, in spite of its uninspiring short-term performance. Accordingly, shareholders will be pleased, but also have some questions to ponder about the last 12 months.

Turning to the outlook, the next year should generate growth of 13% as estimated by the ten analysts watching the company. With the industry predicted to deliver 78% growth, the company is positioned for a weaker revenue result.

With this information, we find it interesting that Frontier Group Holdings is trading at a fairly similar P/S compared to the industry. 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.

The Key Takeaway

Its shares have lifted substantially and now Frontier Group Holdings' 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.

Given that Frontier Group Holdings' 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. Circumstances like this present a risk to current and prospective investors who may see share prices fall if the low revenue growth impacts the sentiment.
