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

The formula for P/E is:

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

Or for Ameresco:

P/E of 30.88 = USD22.54 Ã· USD0.73 (Based on the trailing twelve months to September 2019.)

### Is A High Price-to-Earnings Ratio Good?

A higher P/E ratio means that buyers have to pay a higher price for each USD1 the company has earned over the last year. That is not a good or a bad thing per se, but a high P/E does imply buyers are optimistic about the future.

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

We can get an indication of market expectations by looking at the P/E ratio. You can see in the image below that the average P/E (16.0) for companies in the construction industry is lower than Ameresco's P/E.

Ameresco's P/E tells us that market participants think the company will perform better than its industry peers, going forward. The market is optimistic about the future, but that doesn't guarantee future growth. So investors should delve deeper. I like to check if company insiders have been buying or selling.

### 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. Therefore, even if you pay a high multiple of earnings now, that multiple will become lower in the future. A lower P/E should indicate the stock is cheap relative to others -- and that may attract buyers.

Ameresco shrunk earnings per share by 34% over the last year. But EPS is up 59% over the last 5 years.

### 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. In other words, it does not consider any debt or cash that the company may have on the balance sheet. Hypothetically, a company could reduce its future P/E ratio by spending its cash (or taking on debt) to achieve higher earnings.

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.

### Ameresco's Balance Sheet

Ameresco has net debt equal to 39% of its market cap. You'd want to be aware of this fact, but it doesn't bother us.

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

Ameresco trades on a P/E ratio of 30.9, which is above its market average of 16.5. With a bit of debt, but a lack of recent growth, it's safe to say the market is expecting improved profit performance from the company, in the next few years.
