It is hard to get excited after looking at Lontium Semiconductor's (SHSE:688486) recent performance, when its stock has declined 36% over the past three months. However, stock prices are usually driven by a company's financials over the long term, which in this case look pretty respectable. Particularly, we will be paying attention to Lontium Semiconductor's ROE today.

Return on equity or ROE is an important factor to be considered by a shareholder because it tells them how effectively their capital is being reinvested. In short, ROE shows the profit each dollar generates with respect to its shareholder investments.

How Is ROE Calculated?

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 Lontium Semiconductor is:

6.4% = CN¥90m ÷ CN¥1.4b (Based on the trailing twelve months to September 2023).

The 'return' is the income the business earned over the last year. One way to conceptualize this is that for each CN¥1 of shareholders' capital it has, the company made CN¥0.06 in profit.

What Is The Relationship Between ROE And Earnings Growth?

So far, we've learned that ROE is a measure of a company's profitability. We now need to evaluate how much profit the company reinvests or "retains" for future growth which then gives us an idea about the growth potential of the company. Generally speaking, other things being equal, firms with a high return on equity and profit retention, have a higher growth rate than firms that don't share these attributes.

Lontium Semiconductor's Earnings Growth And 6.4% ROE

When you first look at it, Lontium Semiconductor's ROE doesn't look that attractive. However, given that the company's ROE is similar to the average industry ROE of 6.3%, we may spare it some thought. On the other hand, Lontium Semiconductor reported a moderate 20% net income growth over the past five years. Given the slightly low ROE, it is likely that there could be some other aspects that are driving this growth. For instance, the company has a low payout ratio or is being managed efficiently.

We then compared Lontium Semiconductor's net income growth with the industry and found that the company's growth figure is lower than the average industry growth rate of 27% in the same 5-year period, which is a bit concerning.

Earnings growth is an important metric to consider when valuing a stock. It's important for an investor to know whether the market has priced in the company's expected earnings growth (or decline). This then helps them determine if the stock is placed for a bright or bleak future.

Is Lontium Semiconductor Making Efficient Use Of Its Profits?

Lontium Semiconductor has a three-year median payout ratio of 27%, which implies that it retains the remaining 73% of its profits. This suggests that its dividend is well covered, and given the decent growth seen by the company, it looks like management is reinvesting its earnings efficiently.

While Lontium Semiconductor has been growing its earnings, it only recently started to pay dividends which likely means that the company decided to impress new and existing shareholders with a dividend.

Summary

In total, it does look like Lontium Semiconductor has some positive aspects to its business. Namely, its respectable earnings growth, which it achieved due to it retaining most of its profits. However, given the low ROE, investors may not be benefitting from all that reinvestment after all.
