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

The formula for P/E is:

Price to Earnings Ratio = Share Price Ã· Earnings per Share (EPS)

Or for Rubis:

P/E of 18.04 = â‚¬52.15 Ã· â‚¬2.89 (Based on the trailing twelve months to June 2019.)

### Is A High P/E 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 Does Rubis's P/E Ratio Compare To Its Peers?

One good way to get a quick read on what market participants expect of a company is to look at its P/E ratio. As you can see below, Rubis has a higher P/E than the average company (16.5) in the gas utilities industry.

That means that the market expects Rubis will outperform other companies in its industry. 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

Probably the most important factor in determining what P/E a company trades on is the earnings growth. If earnings are growing quickly, then the 'E' in the equation will increase faster than it would otherwise. And in that case, the P/E ratio itself will drop rather quickly. And as that P/E ratio drops, the company will look cheap, unless its share price increases.

Rubis's earnings per share grew by -6.7% in the last twelve months. And it has bolstered its earnings per share by 16% per year over the last five years.

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

It's important to note that the P/E ratio considers the market capitalization, not the enterprise value. 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 expenditure might be good or bad, in the long term, but the point here is that the balance sheet is not reflected by this ratio.

### Is Debt Impacting Rubis's P/E?

Rubis has net debt worth 17% of its market capitalization. It would probably deserve a higher P/E ratio if it was net cash, since it would have more options for growth.

### The Bottom Line On Rubis's P/E Ratio

Rubis's P/E is 18.0 which is about average (17.2) in the FR market. When you consider the modest EPS growth last year (along with some debt), it seems the market thinks the growth is sustainable.
