### How Do I Calculate A Price To Earnings Ratio?

The formula for P/E is:

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

Or for GMS:

P/E of 15.46 = \$18.21 Ã· \$1.18 (Based on the trailing twelve months to January 2019.)

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

A higher P/E ratio means that investors are paying a higher price for each \$1 of company earnings. 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 Growth Rates Impact P/E Ratios

Probably the most important factor in determining what P/E a company trades on is the earnings growth. If earnings are growing quickly, then the 'E' in the equation will increase faster than it would otherwise. That means even if the current P/E is high, it will reduce over time if the share price stays flat. So while a stock may look expensive based on past earnings, it could be cheap based on future earnings.

GMS shrunk earnings per share by 28% over the last year. But it has grown its earnings per share by 74% per year over the last three years.

### How Does GMS's P/E Ratio Compare To Its Peers?

One good way to get a quick read on what market participants expect of a company is to look at its P/E ratio. As you can see below GMS has a P/E ratio that is fairly close for the average for the trade distributors industry, which is 16.2.

GMS's P/E tells us that market participants think its prospects are roughly in line with its industry. If the company has better than average prospects, then the market might be underestimating it. Checking factors such as the tenure of the board and management could help you form your own view on if that will happen.

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

The 'Price' in P/E reflects the market capitalization of the company. In other words, it does not consider any debt or cash that the company may have on the balance sheet. The exact same company would hypothetically deserve a higher P/E ratio if it had a strong balance sheet, than if it had a weak one with lots of debt, because a cashed up company can spend on 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.

### How Does GMS's Debt Impact Its P/E Ratio?

GMS's net debt is considerable, at 158% of its market cap. If you want to compare its P/E ratio to other companies, you must keep in mind that these debt levels would usually warrant a relatively low P/E.

### The Verdict On GMS's P/E Ratio

GMS has a P/E of 15.5. That's below the average in the US market, which is 17.8. Given meaningful debt, and a lack of recent growth, the market looks to be extrapolating this recent performance; reflecting low expectations for the future.
