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. By way of learning-by-doing, we'll look at ROE to gain a better understanding of Exponent, Inc. (NASDAQ:EXPO).
Our data shows Exponent has a return on equity of 22% for the last year. That means that for every $1 worth of shareholders' equity, it generated $0.22 in profit.
How Do You Calculate Return On Equity?
The formula for return on equity is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for Exponent:
22% = US$79m ÷ US$357m (Based on the trailing twelve months to September 2019.)
Most know that net profit is the total earnings after all expenses, but the concept of shareholders' equity is a little more complicated. It is all earnings retained by the company, plus any capital paid in by shareholders. You can calculate shareholders' equity by subtracting the company's total liabilities from its 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 yearly profit. 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 Exponent Have A Good Return On Equity?
One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. Pleasingly, Exponent has a superior ROE than the average (14%) company in the Professional Services industry.
That is a good sign. In my book, a high ROE almost always warrants a closer look. For example, I often check if insiders have been buying shares.
The Importance Of Debt To Return On Equity
Virtually all companies need money to invest in the business, to grow profits. That cash can come from retained earnings, issuing new shares (equity), or debt. In the case of the first and second options, the ROE will reflect this use of cash, for growth. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders' equity. That will make the ROE look better than if no debt was used.
Combining Exponent's Debt And Its 22% Return On Equity
Shareholders will be pleased to learn that Exponent has not one iota of net debt! Its ROE already suggests it is a good business, but the fact it has achieved this -- and doesn't borrowings -- makes it worthy of further consideration, in my view. At the end of the day, when a company has zero debt, it is in a better position to take future growth opportunities.
But It's Just One Metric
Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. 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 when a business is high quality, the market often bids it up to a price that reflects this. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
