# Rumo S.A. (BVMF:RAIL3) Delivered A Weaker ROE Than Its Industry

•  Updated

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 Rumo S.A. (BVMF:RAIL3).

Return on equity or ROE is a key measure used to assess how efficiently a company's management is utilizing the company's capital. Put another way, it reveals the company's success at turning shareholder investments into profits.

Check out our latest analysis for Rumo

### How Do You 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 Rumo is:

1.0% = R\$156m ÷ R\$15b (Based on the trailing twelve months to December 2021).

The 'return' is the amount earned after tax over the last twelve months. One way to conceptualize this is that for each R\$1 of shareholders' capital it has, the company made R\$0.01 in profit.

### Does Rumo Have A Good ROE?

By comparing a company's ROE with its industry average, we can get a quick measure of how good it is. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As is clear from the image below, Rumo has a lower ROE than the average (20%) in the Transportation industry.

Unfortunately, that's sub-optimal. Although, we think that a lower ROE could still mean that a company has the opportunity to better its returns with the use of leverage, provided its existing debt levels are low. A high debt company having a low ROE is a different story altogether and a risky investment in our books. To know the 3 risks we have identified for Rumo visit our risks dashboard for free.

### How Does Debt Impact ROE?

Most companies need money -- from somewhere -- to grow their profits. That cash can come from issuing shares, retained earnings, or debt. In the case of the first and second options, the ROE will reflect this use of cash, for growth. In the latter case, the use of debt will improve the returns, but will not change the equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

### Rumo's Debt And Its 1.0% ROE

It's worth noting the high use of debt by Rumo, leading to its debt to equity ratio of 1.45. Its ROE is quite low, even with the use of significant debt; that's not a good result, in our opinion. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.

### Conclusion

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. In our books, the highest quality companies have high return on equity, despite low debt. All else being equal, a higher ROE is better.

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.
