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 Electro-Sensors is:

3.1% = US$440k ÷ US$14m (Based on the trailing twelve months to September 2024).

The 'return' is the amount earned after tax over the last twelve months. Another way to think of that is that for every $1 worth of equity, the company was able to earn $0.03 in profit.

What Is The Relationship Between ROE And Earnings Growth?

So far, we've learned that ROE is a measure of a company's profitability. 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.

Electro-Sensors' Earnings Growth And 3.1% ROE

It is hard to argue that Electro-Sensors' ROE is much good in and of itself. Not just that, even compared to the industry average of 10%, the company's ROE is entirely unremarkable. However, we we're pleasantly surprised to see that Electro-Sensors grew its net income at a significant rate of 28% in the last five years. We believe that there might 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.

Next, on comparing with the industry net income growth, we found that Electro-Sensors' growth is quite high when compared to the industry average growth of 14% in the same period, which is great to see.

Earnings growth is an important metric to consider when valuing a stock. The investor should try to establish if the expected growth or decline in earnings, whichever the case may be, is priced in. By doing so, they will have an idea if the stock is headed into clear blue waters or if swampy waters await. Is Electro-Sensors fairly valued compared to other companies?

Is Electro-Sensors Making Efficient Use Of Its Profits?

Electro-Sensors 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 Electro-Sensors certainly does have some positive factors to consider. Despite its low rate of return, the fact that the company reinvests a very high portion of its profits into its business, no doubt contributed to its high earnings growth. 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.
