With A Return On Equity Of 11%, Has A2A S.p.A.'s (BIT:A2A) Management Done Well?

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 A2A S.p.A. (BIT:A2A).

A2A has a ROE of 11%, based on the last twelve months. One way to conceptualize this, is that for each €1 of shareholders' equity it has, the company made €0.11 in profit.

How Do I Calculate Return On Equity?

The formula for return on equity is:

Return on Equity = Net Profit ÷ Shareholders' Equity

Or for A2A:

11% = 375 ÷ €3.4b (Based on the trailing twelve months to September 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 the money paid into the company from shareholders, plus any earnings retained. You can calculate shareholders' equity by subtracting the company's total liabilities from its total assets.

What Does ROE Mean?

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. A higher profit will lead to a higher ROE. So, all else equal, investors should like a high ROE. Clearly, then, one can use ROE to compare different companies.

Does A2A Have A Good Return On Equity?

Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. The image below shows that A2A has an ROE that is roughly in line with the Integrated Utilities industry average (13%).

That's not overly surprising. ROE tells us about the quality of the business, but it does not give us much of an idea if the share price is cheap. If you like to buy stocks alongside management, then you might just love this freelist of companies. (Hint: insiders have been buying them).

How Does Debt Impact Return On Equity?

Most companies need money -- from somewhere -- to grow their profits. That cash can come from retained earnings, issuing new shares (equity), 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 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.

A2A's Debt And Its 11% ROE

It's worth noting the significant use of debt by A2A, leading to its debt to equity ratio of 1.18. while its ROE is respectable, it is worth keeping in mind that there is usually a limit to how much debt a company can use. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.

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 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 I think it may be worth checking this freereport on analyst forecasts for the company.

Of course A2A may not be the best stock to buy. So you may wish to see this free collection of other companies that have high ROE and low debt.
