How Do You Calculate A P/E Ratio?

The formula for price to earnings is:

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

Or for Rosenbauer International:

P/E of 12.74 = €39.5 ÷ €3.1 (Based on the year to June 2019.)

Is A High Price-to-Earnings Ratio Good?

A higher P/E ratio means that investors are paying a higher price for each €1 of company earnings. 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 Rosenbauer International's P/E Ratio Compare To Its Peers?

We can get an indication of market expectations by looking at the P/E ratio. If you look at the image below, you can see Rosenbauer International has a lower P/E than the average (16) in the machinery industry classification.

WBAG:ROS Price Estimation Relative to Market, September 15th 2019

This suggests that market participants think Rosenbauer International will underperform other companies in its industry. While current expectations are low, the stock could be undervalued if the situation is better than the market assumes. It is arguably worth checking if insiders are buying shares, because that might imply they believe the stock is undervalued.

How Growth Rates Impact P/E Ratios

Companies that shrink earnings per share quickly will rapidly decrease the 'E' in the equation. Therefore, even if you pay a low multiple of earnings now, that multiple will become higher in the future. A higher P/E should indicate the stock is expensive relative to others -- and that may encourage shareholders to sell.

Rosenbauer International's earnings made like a rocket, taking off 103% last year. Unfortunately, earnings per share are down 5.7% a year, over 5 years.

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. 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.

Spending on growth might be good or bad a few years later, but the point is that the P/E ratio does not account for the option (or lack thereof).

So What Does Rosenbauer International's Balance Sheet Tell Us?

Rosenbauer International has net debt worth a very significant 139% of its market capitalization. This level of debt justifies a relatively low P/E, so remain cognizant of the debt, if you're comparing it to other stocks.

The Bottom Line On Rosenbauer International's P/E Ratio

Rosenbauer International has a P/E of 12.7. That's below the average in the AT market, which is 14.3. The company has a meaningful amount of debt on the balance sheet, but that should not eclipse the solid earnings growth. The low P/E ratio suggests current market expectations are muted, implying these levels of growth will not continue.
