With a price-to-earnings (or “P/E”) ratio of 42.3x Planet Fitness, Inc. (NYSE:PLNT) may be sending very bearish signals at the moment, given that almost half of all companies in the United States have P/E ratios under 18x and even P/E’s lower than 10x are not unusual. Although, it’s not wise to just take the P/E at face value as there may be an explanation why it’s so lofty.

Planet Fitness certainly has been doing a good job lately as its earnings growth has been positive while most other companies have been seeing their earnings go backwards. The P/E is probably high because investors think the company will continue to navigate the broader market headwinds better than most. You’d really hope so, otherwise you’re paying a pretty hefty price for no particular reason.

Is There Enough Growth For Planet Fitness?

The only time you’d be truly comfortable seeing a P/E as steep as Planet Fitness’ is when the company’s growth is on track to outshine the market decidedly.

If we review the last year of earnings growth, the company posted a terrific increase of 24%. The latest three year period has also seen an excellent 507% overall rise in EPS, aided by its short-term performance. Therefore, it’s fair to say the earnings growth recently has been superb for the company.

Shifting to the future, estimates from the analysts covering the company suggest earnings should grow by 15% per year over the next three years. Meanwhile, the rest of the market is forecast to only expand by 10% per year, which is noticeably less attractive.

In light of this, it’s understandable that Planet Fitness’ P/E sits above the majority of other companies. It seems most investors are expecting this strong future growth and are willing to pay more for the stock.

The Final Word

We’d say the price-to-earnings ratio’s power isn’t primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

We’ve established that Planet Fitness maintains its high P/E on the strength of its forecast growth being higher than the wider market, as expected. At this stage investors feel the potential for a deterioration in earnings isn’t great enough to justify a lower P/E ratio. Unless these conditions change, they will continue to provide strong support to the share price.
