# Should You Be Tempted To Sell EnerSys (NYSE:ENS) Because Of Its P/E Ratio?

This article is written for those who want to get better at using price to earnings ratios (P/E ratios). Weâ€™ll show how you can use EnerSysâ€™s (NYSE:ENS) P/E ratio to inform your assessment of the investment opportunity. EnerSys has a P/E ratio of 27.45, based on the last twelve months. In other words, at todayâ€™s prices, investors are paying \$27.45 for every \$1 in prior year profit.

### How Do You Calculate A P/E Ratio?

The formula for price to earnings is:

Price to Earnings Ratio = Share Price Ã· Earnings per Share (EPS)

Or for EnerSys:

P/E of 27.45 = \$79.29 Ã· \$2.89 (Based on the year to September 2018.)

### 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. That isnâ€™t a good or a bad thing on its own, but a high P/E means that buyers have a higher opinion of the businessâ€™s prospects, relative to stocks with a lower P/E.

### How Growth Rates Impact P/E Ratios

If earnings fall then in the future the â€˜Eâ€™ will be lower. That means unless the share price falls, the P/E will increase in a few years. Then, a higher P/E might scare off shareholders, pushing the share price down.

EnerSysâ€™s earnings per share fell by 23% in the last twelve months. And EPS is down 4.2% a year, over the last 5 years. This might lead to muted expectations.

### How Does EnerSysâ€™s P/E Ratio Compare To Its Peers?

The P/E ratio essentially measures market expectations of a company. You can see in the image below that the average P/E (14.7) for companies in the electrical industry is lower than EnerSysâ€™s P/E.

EnerSysâ€™s P/E tells us that market participants think the company will perform better than its industry peers, going forward. Clearly the market expects growth, but it isnâ€™t guaranteed. So investors should always consider the P/E ratio alongside other factors, such as whether company directors have been buying shares.

### Donâ€™t Forget: The P/E Does Not Account For Debt or Bank Deposits

Donâ€™t forget that the P/E ratio considers market capitalization. In other words, it does not consider any debt or cash that the company may have on the balance sheet. Theoretically, a business can improve its earnings (and produce a lower P/E in the future), by taking on debt (or spending its remaining cash).

Spending on growth might be good or bad a few years later, but the point is that the P/E ratio does not account for the option (or lack thereof).

### EnerSysâ€™s Balance Sheet

EnerSysâ€™s net debt is 2.0% of its market cap. So it doesnâ€™t have as many options as it would with net cash, but its debt would not have much of an impact on its P/E ratio.

### The Verdict On EnerSysâ€™s P/E Ratio

EnerSys has a P/E of 27.5. Thatâ€™s higher than the average in the US market, which is 17. With some debt but no EPS growth last year, the market has high expectations of future profits.
