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. We’ll use ROE to examine Lonza Group Ltd (VTX:LONN), by way of a worked example.
Over the last twelve months Lonza Group has recorded a ROE of 10%. One way to conceptualize this, is that for each CHF1 of shareholders’ equity it has, the company made CHF0.10 in profit.

How Do You Calculate ROE?
The formula for return on equity is:
Return on Equity = Net Profit ÷ Shareholders’ Equity
Or for Lonza Group:
10% = 655 ÷ CHF6.3b (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 the capital paid in by shareholders, plus any retained earnings. The easiest way to calculate shareholders’ equity is to subtract the company’s total liabilities from the total assets.
What Does ROE Mean?
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 amount earned after tax over the last twelve months. The higher the ROE, the more profit the company is making. So, all else being equal, a high ROE is better than a low one. That means ROE can be used to compare two businesses.
Does Lonza Group Have A Good Return On Equity?
One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. The image below shows that Lonza Group has an ROE that is roughly in line with the Life Sciences industry average (12%).
That’s not overly surprising. ROE doesn’t tell us if the share price is low, but it can inform us to the nature of the business. For those looking for a bargain, other factors may be more important.

How Does Debt Impact Return On Equity?
Most companies need money — from somewhere — to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. 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. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.
