How Do You Calculate A P/E Ratio?

The formula for price to earnings is:

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

Or for EnerSys:

P/E of 18.06 = $68.35 ÷ $3.79 (Based on the trailing twelve months to March 2019.)

Is A High Price-to-Earnings Ratio Good?

A higher P/E ratio means that investors are paying a higher price for each $1 of company earnings. All else being equal, it's better to pay a low price -- but as Warren Buffett said, 'It's far better to buy a wonderful company at a fair price than a fair company at a wonderful price.'

Does EnerSys Have A Relatively High Or Low P/E For Its Industry?

That indicates that the market expects EnerSys will perform roughly in line with other companies in its industry. If the company has better than average prospects, then the market might be underestimating it. Checking factors such as director buying and selling. could help you form your own view on if that will happen.

How Growth Rates Impact P/E Ratios

Generally speaking the rate of earnings growth has a profound impact on a company's P/E multiple. Earnings growth means that in the future the 'E' will be higher. Therefore, even if you pay a high multiple of earnings now, that multiple will become lower in the future. Then, a lower P/E should attract more buyers, pushing the share price up.

EnerSys increased earnings per share by a whopping 35% last year. And it has bolstered its earnings per share by 3.6% per year over the last five years. So we'd generally expect it to have a relatively high P/E ratio.

Don't Forget: The P/E Does Not Account For Debt or Bank Deposits

One drawback of using a P/E ratio is that it considers market capitalization, but not the balance sheet. Thus, the metric does not reflect cash or debt held by the company. Theoretically, a business can improve its earnings (and produce a lower P/E in the future) by investing in growth. That means taking on debt (or spending its cash).

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.

So What Does EnerSys's Balance Sheet Tell Us?

EnerSys has net debt equal to 25% of its market cap. While it's worth keeping this in mind, it isn't a worry.

The Bottom Line On EnerSys's P/E Ratio

EnerSys's P/E is 18.1 which is about average (18.1) in the US market. Given it has reasonable debt levels, and grew earnings strongly last year, the P/E indicates the market has doubts this growth can be sustained. Since analysts are predicting growth will continue, one might expect to see a higher P/E so it may be worth looking closer.
