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

The formula for price to earnings is:

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

Or for Stantec:

P/E of 20.77 = CA\$32.96 Ã· CA\$1.59 (Based on the year 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 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. 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.

Stantec saw earnings per share decrease by 5.6% last year.

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

The P/E ratio essentially measures market expectations of a company. The image below shows that Stantec has a P/E ratio that is roughly in line with the professional services industry average (20.8).

That indicates that the market expects Stantec will perform roughly in line with other companies in its industry. So if Stantec actually outperforms its peers going forward, that should be a positive for the share price. Checking factors such as the tenure of the board and management could help you form your own view on if that will happen.

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

It's important to note that the P/E ratio considers the market capitalization, not the enterprise value. That means it doesn't take debt or cash into account. 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.

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

Stantec's net debt equates to 45% of its market capitalization. You'd want to be aware of this fact, but it doesn't bother us.

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

Stantec trades on a P/E ratio of 20.8, which is above the CA market average of 14.8. With modest debt but no EPS growth in the last year, it's fair to say the P/E implies some optimism about future earnings, from the market.
