Can Nomura Micro Science Co., Ltd. (TSE:6254) Maintain Its Strong Returns?
Many investors are still learning about the various metrics that can be useful when analysing a stock. This article is for those who would like to learn about Return On Equity (ROE). We'll use ROE to examine Nomura Micro Science Co., Ltd. (TSE:6254), 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.
How To Calculate Return On Equity?
ROE can be calculated by using the formula:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
So, based on the above formula, the ROE for Nomura Micro Science is:
29% = JP¥10b ÷ JP¥35b (Based on the trailing twelve months to June 2025).
The 'return' refers to a company's earnings over the last year. So, this means that for every ¥1 of its shareholder's investments, the company generates a profit of ¥0.29.

Does Nomura Micro Science Have A Good ROE?
Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As is clear from the image below, Nomura Micro Science has a better ROE than the average (7.6%) in the Machinery industry.
That is a good sign. However, bear in mind that a high ROE doesn’t necessarily indicate efficient profit generation. Aside from changes in net income, a high ROE can also be the outcome of high debt relative to equity, which indicates risk. Our risks dashboardshould have the 2 risks we have identified for Nomura Micro Science.
The Importance Of Debt To Return On Equity
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. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.
Combining Nomura Micro Science's Debt And Its 29% Return On Equity
Nomura Micro Science does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.36. While no doubt that its ROE is impressive, we would have been even more impressed had the company achieved this with lower debt. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.
Summary
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 the same ROE, then I would generally prefer the one with less debt.
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.
