What Ecolab Inc.'s (NYSE:ECL) P/E Is Not Telling You

With a price-to-earnings (or "P/E") ratio of 36.2x Ecolab Inc. (NYSE:ECL) 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 11x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/E.

With earnings growth that's superior to most other companies of late, Ecolab has been doing relatively well. 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.

Is There Enough Growth For Ecolab?

Ecolab's P/E ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better than the market.

Retrospectively, the last year delivered an exceptional 36% gain to the company's bottom line. Pleasingly, EPS has also lifted 92% 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 9.3% per year as estimated by the analysts watching the company. That's shaping up to be similar to the 10% per year growth forecast for the broader market.

In light of this, it's curious that Ecolab'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. These shareholders may be setting themselves up for disappointment if the P/E falls to levels more in line with the growth outlook.

The Bottom Line On Ecolab's P/E

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 Ecolab 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.
