# Allegheny Technologies Incorporated (NYSE:ATI) Delivered A Weaker ROE Than Its Industry

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. We'll use ROE to examine Allegheny Technologies Incorporated (NYSE:ATI), by way of a worked example.

Over the last twelve months Allegheny Technologies has recorded a ROE of 9.1%. One way to conceptualize this, is that for each \$1 of shareholders' equity it has, the company made \$0.09 in profit.

### How Do You Calculate Return On Equity?

The formula for return on equity is:

Return on Equity = Net Profit Ã· Shareholders' Equity

Or for Allegheny Technologies:

9.1% = US\$182m Ã· US\$2.1b (Based on the trailing twelve months to June 2019.)

Most readers would understand what net profit is, but itâ€™s worth explaining the concept of shareholdersâ€™ equity. It is all earnings retained by the company, plus any capital paid in by shareholders. You can calculate shareholders' equity by subtracting the company's total liabilities from its total assets.

### What Does ROE Signify?

ROE looks at the amount a company earns relative to the money it has kept within the business. The 'return' is the amount earned after tax over the last twelve months. That means that the higher the ROE, the more profitable the company is. So, all else equal, investors should like a high ROE. That means it can be interesting to compare the ROE of different companies.

### Does Allegheny Technologies 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. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. If you look at the image below, you can see Allegheny Technologies has a lower ROE than the average (12%) in the Metals and Mining industry classification.

That's not what we like to see. It is better when the ROE is above industry average, but a low one doesn't necessarily mean the business is overpriced. Still, shareholders might want to check if insiders have been selling.

### Why You Should Consider Debt When Looking At ROE

Virtually all companies need money to invest in the business, to grow profits. That cash can come from issuing shares, retained earnings, 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.

### Combining Allegheny Technologies's Debt And Its 9.1% Return On Equity

Although Allegheny Technologies does use debt, its debt to equity ratio of 0.72 is still low. I'm not impressed with its ROE, but the debt levels are not too high, indicating the business has decent prospects. Careful use of debt to boost returns is often very good for shareholders. However, it could reduce the company's ability to take advantage of future opportunities.

### In Summary

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. A company that can achieve a high return on equity without debt could be considered a high quality business. If two companies have the same ROE, then I would generally prefer the one with less debt.

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. So I think it may be worth checking this free report on analyst forecasts for the company.
