Should You Be Worried About ON Semiconductor Corporation's (NASDAQ:ON) 6.4% Return On Equity?

Simply Wall St

One of the best investments we can make is in our own knowledge and skill set. With that in mind, this article will work through how we can use Return On Equity (ROE) to better understand a business. We'll use ROE to examine ON Semiconductor Corporation (NASDAQ:ON), by way of a worked example.

Over the last twelve months ON Semiconductor has recorded a ROE of 6.4%. Another way to think of that is that for every $1 worth of equity in the company, it was able to earn $0.06.

How Do I Calculate ROE?

The formula for return on equity is:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

Or for ON Semiconductor:

6.4% = US$214m ÷ US$3.3b (Based on the trailing twelve months to December 2019.)

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 Signify?

Return on Equity measures a company's profitability against the profit it has kept for the business (plus any capital injections). The 'return' is the profit over the last twelve months. That means that the higher the ROE, the more profitable the company is. So, all else equal, investors should like a high ROE. That means ROE can be used to compare two businesses.

Does ON Semiconductor Have A Good Return On Equity?

By comparing a company's ROE with its industry average, we can get a quick measure of how good it is. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As is clear from the image below, ON Semiconductor has a lower ROE than the average (9.8%) in the Semiconductor industry.

That's not what we like to see. We prefer it when the ROE of a company is above the industry average, but it's not the be-all and end-all if it is lower. Nonetheless, it might be wise to check if insiders have been selling.

Why You Should Consider Debt When Looking At ROE

Most companies need money -- from somewhere -- to grow their profits. That cash can come from issuing shares, retained earnings, or debt. In the first two cases, the ROE will capture this use of capital to grow. In the latter case, the use of debt will improve the returns, but will not change the equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

ON Semiconductor's Debt And Its 6.4% ROE

ON Semiconductor clearly uses a significant amount of debt to boost returns, as it has a debt to equity ratio of 1.05. Its ROE isn't too bad, but it would probably be very disappointing if the company had to stop using debt. Investors should think carefully about how a company might perform if it was unable to borrow so easily, because credit markets do change over time.

In Summary

Return on equity is useful for comparing the quality of different businesses. In my book the highest quality companies have high return on equity, despite low debt. If two companies have the same ROE, then I would generally prefer the one with less debt.

But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
