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 AIXTRON:

P/E of 19.7 = €7.5 ÷ €0.38 (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 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 AIXTRON's P/E Ratio Compare To Its Peers?

The P/E ratio indicates whether the market has higher or lower expectations of a company. The image below shows that AIXTRON has a lower P/E than the average (23.2) P/E for companies in the semiconductor industry.

This suggests that market participants think AIXTRON will underperform other companies in its industry.

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. That means even if the current P/E is high, it will reduce over time if the share price stays flat. So while a stock may look expensive based on past earnings, it could be cheap based on future earnings.

AIXTRON increased earnings per share by a whopping 31% last year.

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

Don't forget that the P/E ratio considers market capitalization. So it won't reflect the advantage of cash, or disadvantage of debt. In theory, a company can lower its future P/E ratio by using cash or debt to invest in growth.

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.

So What Does AIXTRON's Balance Sheet Tell Us?

With net cash of €248m, AIXTRON has a very strong balance sheet, which may be important for its business. Having said that, at 29% of its market capitalization the cash hoard would contribute towards a higher P/E ratio.

The Bottom Line On AIXTRON's P/E Ratio

AIXTRON trades on a P/E ratio of 19.7, which is fairly close to the DE market average of 19.7. Its net cash position is the cherry on top of its superb EPS growth. So at a glance we're a bit surprised that AIXTRON does not have a higher P/E ratio.
