Energy Recovery, Inc. (NASDAQ:ERII) Delivered A Weaker ROE Than Its Industry

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 Energy Recovery, Inc. (NASDAQ:ERII).

Over the last twelve months Energy Recovery has recorded a ROE of 11%. Another way to think of that is that for every $1 worth of equity in the company, it was able to earn $0.11.

How Do You Calculate ROE?

The formula for return on equity is:

Return on Equity = Net Profit ÷ Shareholders' Equity

Or for Energy Recovery:

11% = US$13m ÷ US$127m (Based on the trailing twelve months to June 2019.)

It's easy to understand the 'net profit' part of that equation, but 'shareholders' equity' requires further explanation. 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 Signify?

ROE looks at the amount a company earns relative to the money it has kept within the business. The 'return' is the profit 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 Energy Recovery Have A Good Return On Equity?

Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. 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, Energy Recovery has a lower ROE than the average (14%) in the Machinery industry.

That's not what we like to see. It is better when the ROE is above industry average, but a low one doesn't necessarily mean the business is overpriced. Nonetheless, it could be useful to double-check if insiders have sold shares recently.

The Importance Of Debt To Return On Equity

Companies usually need to invest money to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. 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.

Energy Recovery's Debt And Its 11% ROE

One positive for shareholders is that Energy Recovery does not have any net debt! Although I don't find its ROE that impressive, it's worth remembering it achieved these returns without debt. At the end of the day, when a company has zero debt, it is in a better position to take future growth opportunities.

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.

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. 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. So I think it may be worth checking this free report on analyst forecasts for the company.
