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 Keyera Corp. (TSE:KEY).
Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors’ money. In simpler terms, it measures the profitability of a company in relation to shareholder's equity.
The formula for ROE is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
So, based on the above formula, the ROE for Keyera is:
15% = CA$431m ÷ CA$2.8b (Based on the trailing twelve months to September 2025).
The 'return' is the income the business earned over the last year. One way to conceptualize this is that for each CA$1 of shareholders' capital it has, the company made CA$0.15 in profit.

By comparing a company's ROE with its industry average, we can get a quick measure of how good it is. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. As you can see in the graphic below, Keyera has a higher ROE than the average (11%) in the Oil and Gas industry.
That's clearly a positive. 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. Our risks dashboardshould have the 2 risks we have identified for Keyera.
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 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.
It's worth noting the high use of debt by Keyera, leading to its debt to equity ratio of 2.31. There's no doubt its ROE is decent, but the very high debt the company carries is not too exciting to see. 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.
Return on equity is useful for comparing the quality of different businesses. In our books, the highest quality companies have high return on equity, despite low debt. If two companies have around the same level of debt to equity, and one has a higher ROE, I'd generally prefer the one with higher ROE.
But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
