# Should We Worry About Acuity Brands, Inc.’s (NYSE:AYI) 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 Acuity Brands, Inc.’s (NYSE:AYI) P/E ratio and reflect on what it tells us about the company’s share price. What is Acuity Brands’s P/E ratio? Well, based on the last twelve months it is 17.31. In other words, at today’s prices, investors are paying \$17.31 for every \$1 in prior year profit.

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

The formula for P/E is:

Price to Earnings Ratio = Price per Share ÷ Earnings per Share (EPS)

Or for Acuity Brands:

P/E of 17.31 = \$141.76 ÷ \$8.19 (Based on the year to February 2019.)

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

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

P/E ratios primarily reflect market expectations around earnings growth rates. 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. And as that P/E ratio drops, the company will look cheap, unless its share price increases.

Acuity Brands maintained roughly steady earnings over the last twelve months. But EPS is up 18% over the last 5 years.

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

One good way to get a quick read on what market participants expect of a company is to look at its P/E ratio. You can see in the image below that the average P/E (17.2) for companies in the electrical industry is roughly the same as Acuity Brands’s P/E.

That indicates that the market expects Acuity Brands will perform roughly in line with other companies in its industry. If the company has better than average prospects, then the market might be underestimating it. Further research into factors such asmanagement tenure, could help you form your own view on whether that is likely.

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

Don’t forget that the P/E ratio considers market capitalization. So it won’t reflect the advantage of cash, or disadvantage of debt. Hypothetically, a company could reduce its future P/E ratio by spending its cash (or taking on debt) to achieve higher earnings.

While growth expenditure doesn’t always pay off, the point is that it is a good option to have; but one that the P/E ratio ignores.

### How Does Acuity Brands’s Debt Impact Its P/E Ratio?

Net debt totals just 2.2% of Acuity Brands’s market cap. So it doesn’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 Bottom Line On Acuity Brands’s P/E Ratio

Acuity Brands trades on a P/E ratio of 17.3, which is fairly close to the US market average of 18.2. Given it has some debt, and grew earnings a bit last year, the P/E indicates the market is expecting steady ongoing progress.

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.
