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

The formula for P/E is:

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

Or for CS Communication & Systemes:

P/E of 24.60 = €3.800 ÷ €0.154 (Based on the year to December 2019.)

(Note: the above calculation results may not be precise due to rounding.)

### 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. All else being equal, it’s better to pay a low price — but as Warren Buffett said, ‘It’s far better to buy a wonderful company at a fair price than a fair company at a wonderful price’.

### Does CS Communication & Systemes 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 (14.2) for companies in the it industry is lower than CS Communication & Systemes’s P/E.

CS Communication & Systemes’s P/E tells us that market participants think the company will perform better than its industry peers, going forward. Clearly the market expects growth, but it isn’t guaranteed. So investors should always consider the P/E ratio alongside other factors, such as whether company directors have been buying shares.

### 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.

CS Communication & Systemes shrunk earnings per share by 49% over the last year. But over the longer term (5 years) earnings per share have increased by 49%.

### 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).

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.

### CS Communication & Systemes’s Balance Sheet

Net debt totals 66% of CS Communication & Systemes’s market cap. This is a reasonably significant level of debt — all else being equal you’d expect a much lower P/E than if it had net cash.

### The Verdict On CS Communication & Systemes’s P/E Ratio

CS Communication & Systemes trades on a P/E ratio of 24.6, which is above its market average of 14.4. With meaningful debt and a lack of recent earnings growth, the market has high expectations that the business will earn more in the future.
