Badger Meter, Inc.'s (NYSE:BMI) price-to-earnings (or "P/E") ratio of 53.1x might make it look like a strong sell right now compared to the market in the United States, where around half of the companies have P/E ratios below 16x and even P/E's below 9x are quite common. 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.

Recent times have been advantageous for Badger Meter as its earnings have been rising faster than most other companies. It seems that many are expecting the strong earnings performance to persist, which has raised the P/E. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

What Are Growth Metrics Telling Us About The High P/E?

There's an inherent assumption that a company should far outperform the market for P/E ratios like Badger Meter's to be considered reasonable.

Retrospectively, the last year delivered an exceptional 29% gain to the company's bottom line. Pleasingly, EPS has also lifted 74% in aggregate from three years ago, thanks to the last 12 months of growth. Accordingly, shareholders would have probably welcomed those medium-term rates of earnings growth.

Turning to the outlook, the next three years should generate growth of 11% per year as estimated by the five analysts watching the company. With the market predicted to deliver 13% growth per annum, the company is positioned for a comparable earnings result.

In light of this, it's curious that Badger Meter's P/E sits above the majority of other companies. It seems most investors are ignoring the fairly average growth expectations and are willing to pay up for exposure to the stock. Although, additional gains will be difficult to achieve as this level of earnings growth is likely to weigh down the share price eventually.

The Final Word

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

We've established that Badger Meter currently trades on a higher than expected P/E since its forecast growth is only in line with the wider market. When we see an average earnings outlook with market-like growth, we suspect the share price is at risk of declining, sending the high P/E lower. Unless these conditions improve, it's challenging to accept these prices as being reasonable.
