How Do You Calculate Return On Equity?

The formula for return on equity is:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for AltaGas is:

5.6% = CA$471m ÷ CA$8.5b (Based on the trailing twelve months to June 2024).

The 'return' refers to a company's earnings over the last year. One way to conceptualize this is that for each CA$1 of shareholders' capital it has, the company made CA$0.06 in profit.

Does AltaGas Have A Good ROE?

Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. As is clear from the image below, AltaGas has a lower ROE than the average (8.4%) in the Gas Utilities industry.

That certainly isn't ideal. That being said, a low ROE is not always a bad thing, especially if the company has low leverage as this still leaves room for improvement if the company were to take on more debt. A high debt company having a low ROE is a different story altogether and a risky investment in our books. Our risks dashboard should have the 4 risks we have identified for AltaGas.

The Importance Of Debt To Return On Equity

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 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 AltaGas' Debt And Its 5.6% Return On Equity

AltaGas does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.09. With a fairly low ROE, and significant use of debt, it's hard to get excited about this business at the moment. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.
