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). To keep the lesson grounded in practicality, we'll use ROE to better understand NiSource Inc. (NYSE:NI).
Return on equity or ROE is a key measure used to assess how efficiently a company's management is utilizing the company's capital. In other words, it is a profitability ratio which measures the rate of return on the capital provided by the company's shareholders.

How To 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 NiSource is:
9.6% = US$724m ÷ US$7.5b (Based on the trailing twelve months to March 2022).
The 'return' is the amount earned after tax over the last twelve months. So, this means that for every $1 of its shareholder's investments, the company generates a profit of $0.10.
Does NiSource Have A Good Return On Equity?
By comparing a company's ROE with its industry average, we can get a quick measure of how good it is. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. If you look at the image below, you can see NiSource has a similar ROE to the average in the Integrated Utilities industry classification (9.2%).
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 so, this increases its exposure to financial risk. You can see the 3 risks we have identified for NiSource by visiting our risks dashboard for free on our platform here.
The Importance Of Debt To Return On Equity
Virtually all companies need money to invest in the business, to grow 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. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
Combining NiSource's Debt And Its 9.6% Return On Equity
NiSource does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.30. 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.
