While some investors are already well versed in financial metrics (hat tip), this article is for those who would like to learn about Return On Equity (ROE) and why it is important. By way of learning-by-doing, we'll look at ROE to gain a better understanding of Imperial Brands PLC (LON:IMB).

ROE or return on equity is a useful tool to assess how effectively a company can generate returns on the investment it received from its shareholders. In other words, it is a profitability ratio which measures the rate of return on the capital provided by the company's shareholders.

How To Calculate Return On Equity?

The formula for ROE is:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for Imperial Brands is:

43% = UK￡2.2b ÷ UK￡5.1b (Based on the trailing twelve months to March 2024).

The 'return' refers to a company's earnings over the last year. That means that for every ￡1 worth of shareholders' equity, the company generated ￡0.43 in profit.

Does Imperial Brands Have A Good ROE?

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. Pleasingly, Imperial Brands has a superior ROE than the average (24%) in the Tobacco industry.

That is a good sign. With that said, a high ROE doesn't always indicate high profitability. Aside from changes in net income, a high ROE can also be the outcome of high debt relative to equity, which indicates risk.

The Importance Of Debt To 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 debt used for growth will improve returns, but won't affect the total equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

Imperial Brands' Debt And Its 43% ROE

It's worth noting the high use of debt by Imperial Brands, leading to its debt to equity ratio of 2.10. While no doubt that its ROE is impressive, we would have been even more impressed had the company achieved this with lower debt. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.
