# Read This Before You Buy Silgan Holdings Inc. (NASDAQ:SLGN) Because Of Its P/E Ratio

The goal of this article is to teach you how to use price to earnings ratios (P/E ratios). We’ll look at Silgan Holdings Inc.’s (NASDAQ:SLGN) P/E ratio and reflect on what it tells us about the company’s share price. Silgan Holdings has a P/E ratio of 14.93, based on the last twelve months. In other words, at today’s prices, investors are paying \$14.93 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 = Price per Share ÷ Earnings per Share (EPS)

Or for Silgan Holdings:

P/E of 14.93 = \$30.24 ÷ \$2.03 (Based on the trailing twelve months to December 2018.)

### Is A High P/E Ratio Good?

The higher the P/E ratio, the higher the price tag of a business, relative to its trailing 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.’

### 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. When earnings grow, the ‘E’ increases, over time. That means unless the share price increases, the P/E will reduce in a few years. So while a stock may look expensive based on past earnings, it could be cheap based on future earnings.

Silgan Holdings saw earnings per share decrease by 17% last year. But EPS is up 7.0% over the last 5 years.

### Does Silgan Holdings Have A Relatively High Or Low P/E For Its Industry?

The P/E ratio essentially measures market expectations of a company. If you look at the image below, you can see Silgan Holdings has a lower P/E than the average (18.4) in the packaging industry classification.

Silgan Holdings’s P/E tells us that market participants think it will not fare as well as its peers in the same industry. While current expectations are low, the stock could be undervalued if the situation is better than the market assumes. You should delve deeper. I like to check if company insiders have been buying or selling.

### A Limitation: P/E Ratios Ignore Debt and Cash In The Bank

Don’t forget that the P/E ratio considers market capitalization. So it won’t reflect the advantage of cash, or disadvantage of debt. In theory, a company can lower its future P/E ratio by using cash or debt to invest in growth.

Such expenditure might be good or bad, in the long term, but the point here is that the balance sheet is not reflected by this ratio.

### Is Debt Impacting Silgan Holdings’s P/E?

Net debt totals 67% of Silgan Holdings’s market cap. This is a reasonably significant level of debt — all else being equal you’d expect a much lower P/E than if it had net cash.

### The Verdict On Silgan Holdings’s P/E Ratio

Silgan Holdings’s P/E is 14.9 which is below average (18.2) in the US market. The P/E reflects market pessimism that probably arises from the lack of recent EPS growth, paired with significant leverage.

Investors should be looking to buy stocks that the market is wrong about. If the reality for a company is not as bad as the P/E ratio indicates, then the share price should increase as the market realizes this.
