# Muehlhan AG (ETR:M4N) Delivered A Weaker ROE Than Its Industry

While some investors are already well versed in financial metrics (hat tip), this article is for those who would like to learn about Return On Equity (ROE) and why it is important. To keep the lesson grounded in practicality, we'll use ROE to better understand Muehlhan AG (ETR:M4N).

Our data shows Muehlhan has a return on equity of 8.7% for the last year. One way to conceptualize this, is that for each â‚¬1 of shareholders' equity it has, the company made â‚¬0.09 in profit.

### How Do You Calculate Return On Equity?

The formula for ROE is:

Return on Equity = Net Profit Ã· Shareholders' Equity

Or for Muehlhan:

8.7% = â‚¬5.4m Ã· â‚¬68m (Based on the trailing twelve months to September 2019.)

Most readers would understand what net profit is, but itâ€™s worth explaining the concept of shareholdersâ€™ equity. It is all the money paid into the company from shareholders, plus any earnings retained. The easiest way to calculate shareholders' equity is to subtract the company's total liabilities from the total assets.

### What Does ROE Signify?

ROE measures a company's profitability against the profit it retains, and any outside investments. The 'return' is the yearly profit. That means that the higher the ROE, the more profitable the company is. So, all else being equal, a high ROE is better than a low one. Clearly, then, one can use ROE to compare different companies.

### Does Muehlhan Have A Good ROE?

Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. If you look at the image below, you can see Muehlhan has a lower ROE than the average (13%) in the Construction industry classification.

That's not what we like to see. We prefer it when the ROE of a company is above the industry average, but it's not the be-all and end-all if it is lower. Nonetheless, it might be wise to check if insiders have been selling.

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

Companies usually need to invest money to grow their profits. That cash can come from retained earnings, issuing new shares (equity), or debt. In the first two cases, the ROE will capture this use of capital to grow. In the latter case, the debt used for growth will improve returns, but won't affect the total equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

### Muehlhan's Debt And Its 8.7% ROE

Muehlhan has a debt to equity ratio of 0.61, which is far from excessive. Its very respectable ROE, combined with only modest debt, suggests the business is in good shape. Conservative use of debt to boost returns is usually a good move for shareholders, though it does leave the company more exposed to interest rate rises.

### The Key Takeaway

Return on equity is useful for comparing the quality of different businesses. A company that can achieve a high return on equity without debt could be considered a high quality business. 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. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
