Simply Wall St

While some investors are already well versed in financial metrics (hat tip), this article is for those who would like to learn about Return On Equity (ROE) and why it is important. By way of learning-by-doing, we'll look at ROE to gain a better understanding of AeroVironment, Inc. (NASDAQ:AVAV).

Over the last twelve months AeroVironment has recorded a ROE of 9.1%. One way to conceptualize this, is that for each $1 of shareholders' equity it has, the company made $0.091 in profit.

How Do You Calculate Return On Equity?

The formula for ROE is:

Return on Equity = Net Profit ÷ Shareholders' Equity

Or for AeroVironment:

9.1% = US$42m ÷ US$463m (Based on the trailing twelve months to April 2019.)

Most readers would understand what net profit is, but it’s worth explaining the concept of shareholders’ equity. It is all the money paid into the company from shareholders, plus any earnings retained. The easiest way to calculate shareholders' equity is to subtract the company's total liabilities from the total assets.

What Does Return On Equity Mean?

ROE looks at the amount a company earns relative to the money it has kept within the business. The 'return' is the yearly profit. The higher the ROE, the more profit the company is making. So, all else being equal, a high ROE is better than a low one. That means ROE can be used to compare two businesses.

Does AeroVironment Have A Good ROE?

By comparing a company's ROE with its industry average, we can get a quick measure of how good it is. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. As is clear from the image below, AeroVironment has a lower ROE than the average (14%) in the Aerospace & Defense industry.

That's not what we like to see. We'd prefer see an ROE above the industry average, but it might not matter if the company is undervalued. Nonetheless, it could be useful to double-check if insiders have sold shares recently.

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 use of debt will improve the returns, but will not change the equity. That will make the ROE look better than if no debt was used.

Combining AeroVironment's Debt And Its 9.1% Return On Equity

One positive for shareholders is that AeroVironment does not have any net debt! So although its ROE isn't that impressive, we shouldn't judge it harshly on that metric, because it didn't use debt. At the end of the day, when a company has zero debt, it is in a better position to take future growth opportunities.

The Bottom Line On ROE

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. A company that can achieve a high return on equity without debt could be considered a high quality business. All else being equal, a higher ROE is better.

But when a business is high quality, the market often bids it up to a price that reflects this. The rate at which profits are likely to grow, relative to the expectations of profit growth reflected in the current price, must be considered, too.
