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). By way of learning-by-doing, we'll look at ROE to gain a better understanding of IL Science Co., Ltd. (KOSDAQ:307180).
Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors’ money. In other words, it is a profitability ratio which measures the rate of return on the capital provided by the company's shareholders.
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 IL Science is:
5.1% = ₩899m ÷ ₩18b (Based on the trailing twelve months to December 2024).
The 'return' refers to a company's earnings over the last year. Another way to think of that is that for every ₩1 worth of equity, the company was able to earn ₩0.05 in profit.

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. As shown in the graphic below, IL Science has a lower ROE than the average (8.8%) in the Electrical industry classification.
Unfortunately, that's sub-optimal. Although, we think that a lower ROE could still mean that a company has the opportunity to better its returns with the use of leverage, provided its existing debt levels are low. A company with high debt levels and low ROE is a combination we like to avoid given the risk involved.

Companies usually need to invest money to grow their profits. That cash can come from issuing shares, retained earnings, 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. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
It appears that IL Science makes extensive use of debt to improve its returns, because it has an alarmingly high debt to equity ratio of 4.77. We consider it to be a negative sign when a company has a rather low ROE despite a rather high debt to equity.
Return on equity is useful for comparing the quality of different businesses. In our books, the highest quality companies have high return on equity, despite low debt. 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.
