It is hard to get excited after looking at Iofina's (LON:IOF) recent performance, when its stock has declined 31% over the past three months. But if you pay close attention, you might gather that its strong financials could mean that the stock could potentially see an increase in value in the long-term, given how markets usually reward companies with good financial health. In this article, we decided to focus on Iofina's ROE.

How Is ROE Calculated?

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 Iofina is:

15% = US$6.6m ÷ US$45m (Based on the trailing twelve months to December 2023).

The 'return' is the income the business earned over the last year. That means that for every ￡1 worth of shareholders' equity, the company generated ￡0.15 in profit.

What Is The Relationship Between ROE And Earnings Growth?

We have already established that ROE serves as an efficient profit-generating gauge for a company's future earnings. 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. Assuming all else is equal, companies that have both a higher return on equity and higher profit retention are usually the ones that have a higher growth rate when compared to companies that don't have the same features.

Iofina's Earnings Growth And 15% ROE

At first glance, Iofina seems to have a decent ROE. Especially when compared to the industry average of 7.6% the company's ROE looks pretty impressive. Probably as a result of this, Iofina was able to see an impressive net income growth of 50% over the last five years. We believe that there might also be other aspects that are positively influencing the company's earnings growth. For instance, the company has a low payout ratio or is being managed efficiently.

Given that the industry shrunk its earnings at a rate of 2.5% over the last few years, the net income growth of the company is quite impressive.

The basis for attaching value to a company is, to a great extent, tied to its earnings growth. It’s important for an investor to know whether the market has priced in the company's expected earnings growth (or decline). Doing so will help them establish if the stock's future looks promising or ominous. 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 Iofina is trading on a high P/E or a low P/E, relative to its industry.

Is Iofina Efficiently Re-investing Its Profits?

Iofina doesn't pay any regular dividends to its shareholders, meaning that the company has been reinvesting all of its profits into the business. This is likely what's driving the high earnings growth number discussed above.

Conclusion

Overall, we are quite pleased with Iofina's performance. Specifically, we like that the company is reinvesting a huge chunk of its profits at a high rate of return. This of course has caused the company to see substantial growth in its earnings. If the company continues to grow its earnings the way it has, that could have a positive impact on its share price given how earnings per share influence long-term share prices.
