How Is ROE Calculated?

Return on equity 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 Etherstack is:

2.2% = US$186k ÷ US$8.4m (Based on the trailing twelve months to June 2024).

The 'return' refers to a company's earnings over the last year. Another way to think of that is that for every A$1 worth of equity, the company was able to earn A$0.02 in profit.

What Has ROE Got To Do With Earnings Growth?

Thus far, we have learned that ROE measures how efficiently a company is generating its profits. We now need to evaluate how much profit the company reinvests or "retains" for future growth which then gives us an idea about the growth potential of the company. Assuming everything else remains unchanged, the higher the ROE and profit retention, the higher the growth rate of a company compared to companies that don't necessarily bear these characteristics.

Etherstack's Earnings Growth And 2.2% ROE

It is quite clear that Etherstack's ROE is rather low. Even compared to the average industry ROE of 8.0%, the company's ROE is quite dismal. Despite this, surprisingly, Etherstack saw an exceptional 38% net income growth over the past five years. Therefore, there could be other reasons behind this growth. Such as - high earnings retention or an efficient management in place.

We then compared Etherstack's net income growth with the industry and we're pleased to see that the company's growth figure is higher when compared with the industry which has a growth rate of 21% 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. This then helps them determine if the stock is placed for a bright or bleak future. One good indicator of expected earnings growth is the P/E ratio which determines the price the market is willing to pay for a stock based on its earnings prospects. So, you may want to check if Etherstack is trading on a high P/E or a low P/E, relative to its industry.

Is Etherstack Efficiently Re-investing Its Profits?

Etherstack doesn't pay any regular dividends currently which essentially means that it has been reinvesting all of its profits into the business. This definitely contributes to the high earnings growth number that we discussed above.

Conclusion

Overall, we feel that Etherstack certainly does have some positive factors to consider. With a high rate of reinvestment, albeit at a low ROE, the company has managed to see a considerable growth in its earnings. While we won't completely dismiss the company, what we would do, is try to ascertain how risky the business is to make a more informed decision around the company.
