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. By way of learning-by-doing, we'll look at ROE to gain a better understanding of The Greenbrier Companies, Inc. (NYSE:GBX).
Return on equity or ROE is an important factor to be considered by a shareholder because it tells them how effectively their capital is being reinvested. In other words, it is a profitability ratio which measures the rate of return on the capital provided by the company's shareholders.
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 Greenbrier Companies is:
14% = US$238m ÷ US$1.7b (Based on the trailing twelve months to May 2025).
The 'return' refers to a company's earnings over the last year. That means that for every $1 worth of shareholders' equity, the company generated $0.14 in profit.

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. The image below shows that Greenbrier Companies has an ROE that is roughly in line with the Machinery industry average (13%).
So while the ROE is not exceptional, at least its acceptable. Even if the ROE is respectable when compared to the industry, its worth checking if the firm's ROE is being aided by high debt levels. If true, then it is more an indication of risk than the potential. To know the 3 risks we have identified for Greenbrier Companies visit our risks dashboard for free.
Virtually all companies need money to invest in the business, to grow profits. That cash can come from issuing shares, retained earnings, 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 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.
It's worth noting the high use of debt by Greenbrier Companies, leading to its debt to equity ratio of 1.03. There's no doubt its ROE is decent, but the very high debt the company carries is not too exciting to see. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.
Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. 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.
But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider. So you might want to take a peek at this data-rich interactive graph of forecasts for the company.
