Is Northrop Grumman Corporation’s (NYSE:NOC) ROE Of 27% Impressive?

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. To keep the lesson grounded in practicality, we’ll use ROE to better understand Northrop Grumman Corporation (NYSE:NOC).

Northrop Grumman has a ROE of 27%, based on the last twelve months. One way to conceptualize this, is that for each $1 of shareholders’ equity it has, the company made $0.27 in profit.

How Do You Calculate ROE?

The formula for ROE is:

Return on Equity = Net Profit ÷ Shareholders’ Equity

Or for Northrop Grumman:

27% = US$2.2b ÷ US$8.2b (Based on the trailing twelve months to June 2018.)

It’s easy to understand the ‘net profit’ part of that equation, but ‘shareholders’ equity’ requires further explanation. It is all the money paid into the company from shareholders, plus any earnings retained. The easiest way to calculate shareholders’ equity is to subtract the company’s total liabilities from the total assets.

What Does Return On Equity Signify?

Return on Equity measures a company’s profitability against the profit it has kept for the business (plus any capital injections). The ‘return’ is the yearly profit. That means that the higher the ROE, the more profitable the company is. So, all else being equal, a high ROE is better than a low one. That means it can be interesting to compare the ROE of different companies.

Does Northrop Grumman Have A Good ROE?

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. As you can see in the graphic below, Northrop Grumman has a higher ROE than the average (14%) in the aerospace & defense industry.

That’s what I like to see. I usually take a closer look when a company has a better ROE than industry peers. For example you might check if insiders are buying shares.

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 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 Northrop Grumman’s Debt And Its 27% Return On Equity

It’s worth noting the significant use of debt by Northrop Grumman, leading to its debt to equity ratio of 1.84. I think the ROE is impressive, but it would have been assisted by the use of debt. Debt does bring some extra risk, so it’s only really worthwhile when a company generates some decent returns from it.

In Summary

Return on equity is one way we can compare the business quality of different companies. In my book 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.
