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 Kyowa Corporation (TSE:6570), by way of a worked example.
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 ROE is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
So, based on the above formula, the ROE for Kyowa is:
19% = JP¥1.0b ÷ JP¥5.3b (Based on the trailing twelve months to September 2025).
The 'return' refers to a company's earnings over the last year. One way to conceptualize this is that for each ¥1 of shareholders' capital it has, the company made ¥0.19 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. As is clear from the image below, Kyowa has a better ROE than the average (12%) in the Hospitality industry.
That is a good sign. With that said, a high ROE doesn't always indicate high profitability. A higher proportion of debt in a company's capital structure may also result in a high ROE, where the high debt levels could be a huge risk .
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 and second cases, the ROE will reflect this use of cash for investment in the business. 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.
Kyowa clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 1.22. There's no doubt its ROE is decent, but the very high debt the company carries is not too exciting to see. Investors should think carefully about how a company might perform if it was unable to borrow so easily, because credit markets do change over time.
Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. Companies that can achieve high returns on equity without too much debt are generally of good quality. 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.
Having said that, while ROE is a useful indicator of business quality, you'll have to look at a whole range of factors to determine the right price to buy a stock. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
