Many investors are still learning about the various metrics that can be useful when analysing a stock. This article is for those who would like to learn about Return On Equity (ROE). We'll use ROE to examine Northwest Natural Holding Company (NYSE:NWN), by way of a worked example.

Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors’ money. Put another way, it reveals the company's success at turning shareholder investments into profits.

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 Northwest Natural Holding is:

8.0% = US$97m ÷ US$1.2b (Based on the trailing twelve months to December 2023).

The 'return' is the profit over the last twelve months. Another way to think of that is that for every $1 worth of equity, the company was able to earn $0.08 in profit.

Does Northwest Natural Holding Have A Good Return On Equity?

One simple way to determine if a company has a good return on equity is to compare it to the average for 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, Northwest Natural Holding has a lower ROE than the average (12%) in the Gas Utilities industry.

That certainly isn't ideal. 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 company with high debt levels and low ROE is a combination we like to avoid given the risk involved.

How Does Debt Impact Return On Equity?

Companies usually need to invest money to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. In the first and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the debt used for growth will improve returns, but won't affect the total equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

Northwest Natural Holding's Debt And Its 8.0% ROE

Northwest Natural Holding does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.38. Its ROE is quite low, even with the use of significant debt; that's not a good result, in our opinion. 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.
