### How Do You Calculate American Water Works Company’s P/E Ratio?

The formula for price to earnings is:

Price to Earnings Ratio = Share Price ÷ Earnings per Share (EPS)

Or for American Water Works Company:

P/E of 36.73 = \$116.63 ÷ \$3.18 (Based on the trailing twelve months to March 2019.)

### Is A High Price-to-Earnings Ratio Good?

A higher P/E ratio implies that investors pay a higher price for the earning power of the business. That isn’t a good or a bad thing on its own, but a high P/E means that buyers have a higher opinion of the business’s prospects, relative to stocks with a lower P/E.

### How Does American Water Works Company’s P/E Ratio Compare To Its Peers?

We can get an indication of market expectations by looking at the P/E ratio. As you can see below American Water Works Company has a P/E ratio that is fairly close for the average for the water utilities industry, which is 35.3.

Its P/E ratio suggests that American Water Works Company shareholders think that in the future it will perform about the same as other companies in its industry classification.

### How Growth Rates Impact P/E Ratios

P/E ratios primarily reflect market expectations around earnings growth rates. If earnings are growing quickly, then the ‘E’ in the equation will increase faster than it would otherwise. Therefore, even if you pay a high multiple of earnings now, that multiple will become lower in the future. A lower P/E should indicate the stock is cheap relative to others — and that may attract buyers.

American Water Works Company increased earnings per share by a whopping 29% last year. And earnings per share have improved by 8.2% annually, over the last five years. So we’d generally expect it to have a relatively high P/E ratio.

### Remember: P/E Ratios Don’t Consider The Balance Sheet

The ‘Price’ in P/E reflects the market capitalization of the company. Thus, the metric does not reflect cash or debt held by the company. In theory, a company can lower its future P/E ratio by using cash or debt to invest in growth.

Such spending might be good or bad, overall, but the key point here is that you need to look at debt to understand the P/E ratio in context.

### American Water Works Company’s Balance Sheet

Net debt is 42% of American Water Works Company’s market cap. You’d want to be aware of this fact, but it doesn’t bother us.
