Should We Be Delighted With Soitec S.A.'s (EPA:SOI) ROE Of 32%?
Many investors are still learning about the various metrics that can be useful when analysing a stock. This article is for those who would like to learn about Return On Equity (ROE). To keep the lesson grounded in practicality, we'll use ROE to better understand Soitec S.A. (EPA:SOI).
Our data shows Soitec has a return on equity of 32% for the last year. Another way to think of that is that for every €1 worth of equity in the company, it was able to earn €0.32.

How Do You Calculate ROE?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for Soitec:
32% = €104m ÷ €328m (Based on the trailing twelve months to September 2018.)
It's easy to understand the 'net profit' part of that equation, but 'shareholders' equity' requires further explanation. It is all earnings retained by the company, plus any capital paid in by shareholders. The easiest way to calculate shareholders' equity is to subtract the company's total liabilities from the total assets.
What Does ROE Mean?
ROE measures a company's profitability against the profit it retains, and any outside investments. The 'return' is the amount earned after tax over the last twelve months. A higher profit will lead to a higher ROE. So, all else being equal, a high ROE is better than a low one. That means it can be interesting to compare the ROE of different companies.
Does Soitec Have A Good ROE?
Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. As you can see in the graphic below, Soitec has a higher ROE than the average (3.2%) in the Semiconductor industry.
That's clearly a positive. We think a high ROE, alone, is usually enough to justify further research into a company. One data point to check is if insiders have bought shares recently.
Why You Should Consider Debt When Looking At ROE
Virtually all companies need money to invest in the business, to grow profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. In the first and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders' equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.
Soitec's Debt And Its 32% ROE
Although Soitec does use debt, its debt to equity ratio of 0.57 is still low. The combination of modest debt and a very impressive ROE does suggest that the business is high quality. Judicious use of debt to improve returns can certainly be a good thing, although it does elevate risk slightly and reduce future optionality.
In Summary
Return on equity is one way we can compare the business quality of different companies. In my book the highest quality companies have high return on equity, despite low debt. All else being equal, a higher ROE is better.
But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
