Should You Be Excited About AAON, Inc.'s (NASDAQ:AAON) 18% Return On Equity?

Simply Wall St

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 AAON, Inc. (NASDAQ:AAON).

Over the last twelve months AAON has recorded a ROE of 18%. One way to conceptualize this, is that for each $1 of shareholders' equity it has, the company made $0.18 in profit.

How Do You Calculate ROE?

The formula for ROE is:

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

Or for AAON:

18% = US$50m ÷ US$280m (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. The easiest way to calculate shareholders' equity is to subtract the company's total liabilities from the total assets.

What Does ROE Signify?

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. Clearly, then, one can use ROE to compare different companies.

Does AAON 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. 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, AAON has a better ROE than the average (12%) in the Building industry.

That's what I like to see. 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 first and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the use of debt will improve the returns, but will not change the equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

AAON's Debt And Its 18% ROE

Shareholders will be pleased to learn that AAON has not one iota of net debt! Its ROE suggests it is a decent business; and the fact it is not leveraging returns indicates it is well worth watching. 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 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.

Having said that, while ROE is a useful indicator of business quality, you'll have to look at a whole range of factors to determine the right price to buy a stock. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
