How Do I Calculate A Price To Earnings Ratio?

The formula for price to earnings is:

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

Or for AAR:

P/E of 18.78 = $44.56 ÷ $2.37 (Based on the year to August 2019.)

Is A High P/E Ratio Good?

A higher P/E ratio means that buyers have to pay a higher price for each $1 the company has earned over the last year. That isn't necessarily good or bad, but a high P/E implies relatively high expectations of what a company can achieve in the future.

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

The P/E ratio essentially measures market expectations of a company. We can see in the image below that the average P/E (21.0) for companies in the aerospace & defense industry is higher than AAR's P/E.

Its relatively low P/E ratio indicates that AAR shareholders think it will struggle to do as well as other companies in its industry classification. While current expectations are low, the stock could be undervalued if the situation is better than the market assumes. If you consider the stock interesting, further research is recommended. For example, I often monitor director buying and selling.

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. A lower P/E should indicate the stock is cheap relative to others -- and that may attract buyers.

AAR's earnings per share were pretty steady over the last year. But it has grown its earnings per share by 8.9% per year over the last five years.

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

Don't forget that the P/E ratio considers market capitalization. Thus, the metric does not reflect cash or debt held by the company. Theoretically, a business can improve its earnings (and produce a lower P/E in the future) by investing in growth. That means taking on debt (or spending its cash).

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.

Is Debt Impacting AAR's P/E?

Net debt totals 11% of AAR's market cap. That's enough debt to impact the P/E ratio a little; so keep it in mind if you're comparing it to companies without debt.

The Verdict On AAR's P/E Ratio

AAR has a P/E of 18.8. That's around the same as the average in the US market, which is 18.0. With modest debt and some recent earnings growth, it seems likely the market expects a steady performance going forward.
