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 Somnigroup International Inc. (NYSE:SGI).
Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors’ money. Simply put, it is used to assess the profitability of a company in relation to its equity capital.
The formula for return on equity is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
So, based on the above formula, the ROE for Somnigroup International is:
11% = US$317m ÷ US$3.0b (Based on the trailing twelve months to September 2025).
The 'return' is the income the business earned over the last year. That means that for every $1 worth of shareholders' equity, the company generated $0.11 in profit.

One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. If you look at the image below, you can see Somnigroup International has a lower ROE than the average (14%) in the Consumer Durables industry classification.
Unfortunately, that's sub-optimal. That being said, a low ROE is not always a bad thing, especially if the company has low leverage as this still leaves room for improvement if the company were to take on more debt. When a company has low ROE but high debt levels, we would be cautious as the risk involved is too high.

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 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. That will make the ROE look better than if no debt was used.
It's worth noting the high use of debt by Somnigroup International, leading to its debt to equity ratio of 1.51. Its ROE is quite low, even with the use of significant debt; that's not a good result, in our opinion. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.
Return on equity is one way we can compare its business quality of different companies. Companies that can achieve high returns on equity without too much debt are generally of good quality. If two companies have the same ROE, then I would generally prefer the one with less debt.
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.
