With its stock down 39% over the past three months, it is easy to disregard Energy Recovery (NASDAQ:ERII). We, however decided to study the company's financials to determine if they have got anything to do with the price decline. Stock prices are usually driven by a company's financial performance over the long term, and therefore we decided to pay more attention to the company's financial performance. Particularly, we will be paying attention to Energy Recovery's ROE today.

Return on equity or ROE is a key measure used to assess how efficiently a company's management is utilizing the company's capital. In other words, it is a profitability ratio which measures the rate of return on the capital provided by the company's shareholders.

How Do You Calculate Return On Equity?

ROE can be calculated by using the formula:

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

So, based on the above formula, the ROE for Energy Recovery is:

5.8% = US$11m ÷ US$182m (Based on the trailing twelve months to June 2023).

The 'return' is the income the business earned over the last year. Another way to think of that is that for every $1 worth of equity, the company was able to earn $0.06 in profit.

Why Is ROE Important For Earnings Growth?

So far, we've learned that ROE is a measure of a company's profitability. Based on how much of its profits the company chooses to reinvest or "retain", we are then able to evaluate a company's future ability to generate profits. Generally speaking, other things being equal, firms with a high return on equity and profit retention, have a higher growth rate than firms that don't share these attributes.

Energy Recovery's Earnings Growth And 5.8% ROE

At first glance, Energy Recovery's ROE doesn't look very promising. Next, when compared to the average industry ROE of 14%, the company's ROE leaves us feeling even less enthusiastic. Therefore, it might not be wrong to say that the five year net income decline of 13% seen by Energy Recovery was probably the result of it having a lower ROE. However, there could also be other factors causing the earnings to decline. For example, it is possible that the business has allocated capital poorly or that the company has a very high payout ratio.

That being said, we compared Energy Recovery's performance with the industry and were concerned when we found that while the company has shrunk its earnings, the industry has grown its earnings at a rate of 8.2% in the same 5-year period.

The basis for attaching value to a company is, to a great extent, tied to its earnings growth. What investors need to determine next is if the expected earnings growth, or the lack of it, is already built into the share price. Doing so will help them establish if the stock's future looks promising or ominous. Has the market priced in the future outlook for ERII?

Is Energy Recovery Efficiently Re-investing Its Profits?

Energy Recovery doesn't pay any dividend, meaning that the company is keeping all of its profits, which makes us wonder why it is retaining its earnings if it can't use them to grow its business. So there might be other factors at play here which could potentially be hampering growth. For example, the business has faced some headwinds.

Summary

In total, we're a bit ambivalent about Energy Recovery's performance. While the company does have a high rate of profit retention, its low rate of return is probably hampering its earnings growth. With that said, we studied the latest analyst forecasts and found that while the company has shrunk its earnings in the past, analysts expect its earnings to grow in the future.
