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. To keep the lesson grounded in practicality, we’ll use ROE to better understand HMS Bergbau AG (ETR:HMU).
Return on equity or ROE is a key measure used to assess how efficiently a company’s management is utilizing the company’s capital. In other words, it is a profitability ratio which measures the rate of return on the capital provided by the company’s shareholders.
The formula for ROE is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders’ Equity
So, based on the above formula, the ROE for HMS Bergbau is:
25% = €13m ÷ €54m (Based on the trailing twelve months to June 2025).
The ‘return’ is the income the business earned over the last year. So, this means that for every €1 of its shareholder’s investments, the company generates a profit of €0.25.

One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. Pleasingly, HMS Bergbau has a superior ROE than the average (9.7%) in the Trade Distributors industry.
That’s what we like to see. Bear in mind, a high ROE doesn’t always mean superior financial performance. Especially when a firm uses high levels of debt to finance its debt which may boost its ROE but the high leverage puts the company at risk.
Most companies need money — from somewhere — to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. In the case of the first and second options, the ROE will reflect this use of cash, for growth. 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.
HMS Bergbau does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.50. There’s no doubt the ROE is impressive, but it’s worth keeping in mind that the metric could have been lower if the company were to reduce its debt. Debt does bring extra risk, so it’s only really worthwhile when a company generates some decent returns from it.
