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 ATI Inc. (NYSE:ATI).

Return on equity or ROE is a key measure used to assess how efficiently a company's management is utilizing the company's capital. Put another way, it reveals the company's success at turning shareholder investments into profits.

How Is ROE Calculated?

Return on equity 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 ATI is:

23% = US$297m ÷ US$1.3b (Based on the trailing twelve months to June 2023).

The 'return' refers to a company's earnings over the last year. So, this means that for every $1 of its shareholder's investments, the company generates a profit of $0.23.

Does ATI Have A Good ROE?

One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As you can see in the graphic below, ATI has a higher ROE than the average (12%) in the Metals and Mining industry.

That's what we like to see. With that said, a high ROE doesn't always indicate high profitability. A higher proportion of debt in a company's capital structure may also result in a high ROE, where the high debt levels could be a huge risk .

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 two cases, the ROE will capture this use of capital to grow. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders' equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

ATI's Debt And Its 23% ROE

ATI clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 1.30. There's no doubt the ROE is impressive, but it's worth keeping in mind that the metric could have been lower if the company were to reduce its debt. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.

Summary

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. In our books, the highest quality companies have high return on equity, despite low debt. If two companies have the same ROE, then I would generally prefer the one with less debt.

But when a business is high quality, the market often bids it up to a price that reflects this. 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.
