# Is Espey Mfg & Electronics Corp’s (NYSEMKT:ESP) 9.2% ROE Strong Compared To Its Industry?

One of the best investments we can make is in our own knowledge and skill set. With that in mind, this article will work through how we can use Return On Equity (ROE) to better understand a business. We’ll use ROE to examine Espey Mfg & Electronics Corp (NYSEMKT:ESP), by way of a worked example.

Over the last twelve months Espey Mfg. & Electronics has recorded a ROE of 9.2%. Another way to think of that is that for every \$1 worth of equity in the company, it was able to earn \$0.092.

### How Do You Calculate Return On Equity?

The formula for ROE is:

Return on Equity = Net Profit ÷ Shareholders’ Equity

Or for Espey Mfg. & Electronics:

9.2% = US\$3m ÷ US\$33m (Based on the trailing twelve months to June 2018.)

It’s easy to understand the ‘net profit’ part of that equation, but ‘shareholders’ equity’ requires further explanation. It is all earnings retained by the company, plus any capital paid in by shareholders. Shareholders’ equity can be calculated by subtracting the total liabilities of the company from the total assets of the company.

### What Does ROE Signify?

ROE looks at the amount a company earns relative to the money it has kept within the business. The ‘return’ is the yearly profit. The higher the ROE, the more profit the company is making. So, as a general rule, a high ROE is a good thing. Clearly, then, one can use ROE to compare different companies.

### Does Espey Mfg. & Electronics Have A Good ROE?

Arguably the easiest way to assess company’s ROE is to compare it with the average in its industry. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. You can see in the graphic below that Espey Mfg. & Electronics has an ROE that is fairly close to the average for the electrical industry (11%).

That’s neither particularly good, nor bad. ROE can change from year to year, based on decisions that have been made in the past. So it makes sense to check how long the board and CEO have been in place.

### Why You Should Consider Debt When Looking At ROE

Virtually all companies need money to invest in the business, to grow profits. That cash can come from retained earnings, issuing new shares (equity), or debt. In the first and second cases, the ROE will reflect this use of cash for investment in the business. 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.

### Espey Mfg. & Electronics’s Debt And Its 9.2% ROE

One positive for shareholders is that Espey Mfg. & Electronics 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 one way we can compare the business quality of different companies. Companies that can achieve high returns on equity without too much debt are generally of good quality. 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.
