Why CSN Mineração S.A. (BVMF:CMIN3) Looks Like A Quality Company

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. By way of learning-by-doing, we'll look at ROE to gain a better understanding of CSN Mineração S.A. (BVMF:CMIN3).

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.

Trump has pledged to "unleash" American oil and gas and these 15 US stocks have developments that are poised to benefit.

How To Calculate Return On Equity?

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 CSN Mineração is:

24% = R$2.2b ÷ R$9.2b (Based on the trailing twelve months to June 2025).

The 'return' is the income the business earned over the last year. That means that for every R$1 worth of shareholders' equity, the company generated R$0.24 in profit.

Does CSN Mineração Have A Good Return On Equity?

By comparing a company's ROE with its industry average, we can get a quick measure of how good it is. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As is clear from the image below, CSN Mineração has a better ROE than the average (10%) in the Metals and Mining industry.

That is a good sign. Bear in mind, a high ROE doesn't always mean superior financial performance. Aside from changes in net income, a high ROE can also be the outcome of high debt relative to equity, which indicates risk. Our risks dashboardshould have the 3 risks we have identified for CSN Mineração.

Why You Should Consider Debt When Looking At ROE

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 first two cases, the ROE will capture this use of capital to grow. In the latter case, the use of debt will improve the returns, but will not change the equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

Combining CSN Mineração's Debt And Its 24% Return On Equity

CSN Mineração clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 1.00. While its ROE is pretty respectable, the amount of debt the company is carrying currently is not ideal. Investors should think carefully about how a company might perform if it was unable to borrow so easily, because credit markets do change over time.

Conclusion

Return on equity is one way we can compare its business quality of different companies. In our books, the highest quality companies have high return on equity, despite low debt. All else being equal, a higher ROE is better.

But when a business is high quality, the market often bids it up to a price that reflects this. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
