Most readers would already be aware that ACM Research's (NASDAQ:ACMR) stock increased significantly by 73% over the past three months. Given the company's impressive performance, we decided to study its financial indicators more closely as a company's financial health over the long-term usually dictates market outcomes. Particularly, we will be paying attention to ACM Research's ROE today.

Return on equity or ROE is a key measure used to assess how efficiently a company's management is utilizing the company's capital. In short, ROE shows the profit each dollar generates with respect to its shareholder investments.

How Is ROE Calculated?

Return on equity 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 ACM Research is:

10% = US$97m ÷ US$926m (Based on the trailing twelve months to December 2023).

The 'return' is the income the business earned over the last year. One way to conceptualize this is that for each $1 of shareholders' capital it has, the company made $0.10 in profit.

What Is The Relationship Between ROE And Earnings Growth?

Thus far, we have learned that ROE measures how efficiently a company is generating its profits. 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. Assuming everything else remains unchanged, the higher the ROE and profit retention, the higher the growth rate of a company compared to companies that don't necessarily bear these characteristics.

ACM Research's Earnings Growth And 10% ROE

To start with, ACM Research's ROE looks acceptable. Even so, when compared with the average industry ROE of 14%, we aren't very excited. That being the case, the significant five-year 38% net income growth reported by ACM Research comes as a pleasant surprise. We believe that there might be other aspects that are positively influencing the company's earnings growth. For example, it is possible that the company's management has made some good strategic decisions, or that the company has a low payout ratio. Bear in mind, the company does have a respectable ROE. It is just that the industry ROE is higher. So this also does lend some color to the high earnings growth seen by the company.

Next, on comparing with the industry net income growth, we found that ACM Research's growth is quite high when compared to the industry average growth of 29% in the same period, which is great to see.

Earnings growth is an important metric to consider when valuing a stock. The investor should try to establish if the expected growth or decline in earnings, whichever the case may be, is priced in. This then helps them determine if the stock is placed for a bright or bleak future. One good indicator of expected earnings growth is the P/E ratio which determines the price the market is willing to pay for a stock based on its earnings prospects. So, you may want to check if ACM Research is trading on a high P/E or a low P/E, relative to its industry.

Is ACM Research Using Its Retained Earnings Effectively?

ACM Research doesn't pay any dividend to its shareholders, meaning that the company has been reinvesting all of its profits into the business. This is likely what's driving the high earnings growth number discussed above.

Conclusion

In total, we are pretty happy with ACM Research's performance. Specifically, we like that it has been reinvesting a high portion of its profits at a moderate rate of return, resulting in earnings expansion. Having said that, the company's earnings growth is expected to slow down, as forecasted in the current analyst estimates.
