This article is written for those who want to get better at using price to earnings ratios (P/E ratios). We'll apply a basic P/E ratio analysis to Sanofi's ( EPA:SAN ), to help you decide if the stock is worth further research. Sanofi has a P/E ratio of 21.66 , based on the last twelve months. That means that at current prices, buyers pay €21.66 for every €1 in trailing yearly profits.
How Do You Calculate Sanofi's P/E Ratio?
The formula for P/E is:
Price to Earnings Ratio = Price per Share ÷ Earnings per Share (EPS)
Or for Sanofi:
P/E of 21.66 = €75 ÷ €3.46 (Based on the year to December 2018.)
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 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 Growth Rates Impact P/E Ratios
Generally speaking the rate of earnings growth has a profound impact on a company's P/E multiple. That's because companies that grow earnings per share quickly will rapidly increase the 'E' in the equation. And in that case, the P/E ratio itself will drop rather quickly. So while a stock may look expensive based on past earnings, it could be cheap based on future earnings.
Most would be impressed by Sanofi earnings growth of 15% in the last year. And it has bolstered its earnings per share by 4.7% per year over the last five years. So one might expect an above average P/E ratio.
How Does Sanofi'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. If you look at the image below, you can see Sanofi has a lower P/E than the average (24) in the pharmaceuticals industry classification.
This suggests that market participants think Sanofi will underperform other companies in its industry. Since the market seems unimpressed with Sanofi, it's quite possible it could surprise on the upside. It is arguably worth checking if insiders are buying shares , because that might imply they believe the stock is undervalued.
A Limitation: P/E Ratios Ignore Debt and Cash In The Bank
The 'Price' in P/E reflects the market capitalization of the company. That means it doesn't take debt or cash into account. 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.
Is Debt Impacting Sanofi's P/E?
Sanofi's net debt is 19% of its market cap. 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 Sanofi's P/E Ratio
Sanofi's P/E is 21.7 which is above average (16.1) in the FR market. While the company does use modest debt, its recent earnings growth is very good. Therefore, it's not particularly surprising that it has a above average P/E ratio.
