How Do You Calculate ROE?

The formula for ROE is:

Return on Equity = Net Profit ÷ Shareholders' Equity

Or for Alten:

17% = €158m ÷ €972m (Based on the trailing twelve months to December 2018.)

Most know that net profit is the total earnings after all expenses, but the concept of shareholders' equity is a little more complicated. 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 measures a company's profitability against the profit it retains, and any outside investments. The 'return' is the amount earned after tax over the last twelve months. The higher the ROE, the more profit the company is making. So, all else equal, investors should like a high ROE. Clearly, then, one can use ROE to compare different companies.

Does Alten 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. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. Pleasingly, Alten has a superior ROE than the average (11%) company in the IT 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?

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. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

Combining Alten's Debt And Its 17% Return On Equity

Although Alten does use debt, its debt to equity ratio of 0.11 is still low. Its very respectable ROE, combined with only modest debt, suggests the business is in good shape. 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.

The Key Takeaway

Return on equity is useful for comparing the quality of different businesses. In my book the highest quality companies have high return on equity, despite low debt. If two companies have around the same level of debt to equity, and one has a higher ROE, I'd generally prefer the one with higher ROE.

But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
