Mister Car Wash, Inc. (NYSE:MCW) shareholders would be excited to see that the share price has had a great month, posting a 25% gain and recovering from prior weakness. Notwithstanding the latest gain, the annual share price return of 5.8% isn't as impressive.

Since its price has surged higher, Mister Car Wash may be sending very bearish signals at the moment with a price-to-earnings (or "P/E") ratio of 34.6x, since almost half of all companies in the United States have P/E ratios under 19x and even P/E's lower than 11x are not unusual. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

Mister Car Wash hasn't been tracking well recently as its declining earnings compare poorly to other companies, which have seen some growth on average. One possibility is that the P/E is high because investors think this poor earnings performance will turn the corner. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Keen to find out how analysts think Mister Car Wash's future stacks up against the industry? In that case, our free report is a great place to start.

Does Growth Match The High P/E?

In order to justify its P/E ratio, Mister Car Wash would need to produce outstanding growth well in excess of the market.

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 17%. This has erased any of its gains during the last three years, with practically no change in EPS being achieved in total. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.

Turning to the outlook, the next three years should generate growth of 22% each year as estimated by the analysts watching the company. That's shaping up to be materially higher than the 11% per year growth forecast for the broader market.

With this information, we can see why Mister Car Wash is trading at such a high P/E compared to the market. It seems most investors are expecting this strong future growth and are willing to pay more for the stock.
