# Despite Its High P/E Ratio, Is Soitec S.A. (EPA:SOI) Still Undervalued?

This article is for investors who would like to improve their understanding of price to earnings ratios (P/E ratios). We'll look at Soitec S.A.'s (EPA:SOI) P/E ratio and reflect on what it tells us about the company's share price. Soitec has a P/E ratio of 33.06, based on the last twelve months. In other words, at today's prices, investors are paying â‚¬33.06 for every â‚¬1 in prior year profit.

### 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 Soitec:

P/E of 33.06 = â‚¬94.7 Ã· â‚¬2.86 (Based on the year to March 2019.)

### Is A High P/E Ratio Good?

A higher P/E ratio means that investors are paying a higher price for each â‚¬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 Soitec's P/E Ratio Compare To Its Peers?

The P/E ratio essentially measures market expectations of a company. You can see in the image below that the average P/E (26.3) for companies in the semiconductor industry is lower than Soitec's P/E.

That means that the market expects Soitec will outperform other companies in its industry. Clearly the market expects growth, but it isn't guaranteed. So investors should delve deeper. I like to check if company insiders have been buying or selling.

### How Growth Rates Impact P/E Ratios

Earnings growth rates have a big influence on P/E ratios. That's because companies that grow earnings per share quickly will rapidly increase the 'E' in the equation. That means unless the share price increases, the P/E will reduce in a few years. And as that P/E ratio drops, the company will look cheap, unless its share price increases.

Soitec's earnings per share fell by 3.6% in the last twelve months.

### A Limitation: P/E Ratios Ignore Debt and Cash In The Bank

Don't forget that the P/E ratio considers market capitalization. Thus, the metric does not reflect cash or debt held by the company. In theory, a company can lower its future P/E ratio by using cash or debt to invest in growth.

Such spending might be good or bad, overall, but the key point here is that you need to look at debt to understand the P/E ratio in context.

### So What Does Soitec's Balance Sheet Tell Us?

Soitec's net debt is 0.3% of its market cap. It would probably trade on a higher P/E ratio if it had a lot of cash, but I doubt it is having a big impact.

### The Verdict On Soitec's P/E Ratio

Soitec trades on a P/E ratio of 33.1, which is above its market average of 17.6. With modest debt but no EPS growth in the last year, it's fair to say the P/E implies some optimism about future earnings, from the market.
